Title: Mesoporous Metal Sulfide and Metal Selenide Thin films


Phd Researcher Assistant at Sabancı University Nanotechnology Research & Application Center. Parma, Emilia-Romagna, Italy 



Synthesis of the mesoporous CdS and CdSe by using of liquid crystalline templating (LCT) approach has been investigated. The thermal and structural behavior of the [Cd(H2O)4](NO3)2/surfactant (P85 = ((PEO)26(PPO)40(PEO)26)) binary lyotropic liquid crystalline (LLC) systems have been investigated towards synthesis of the mesoporous cadmium sulfide, CdS, or cadmium selenide (CdSe) directly from the mesostructured CdS (or CdSe) thin films. However, the mesostructured CdS/P85 films (at low salt concentrations), which were obtained by reacting [Cd(H2O)4](NO3)2/P85 LLC thin films under H2S atmosphere, are not stable to calcination process and always produced bulk CdO and CdS domains over the thin films. More metal ion containing [Cd(H2O)4](NO3)2-C12EO10-CTAB mesostructured films produced vast amount of HNO3 under the H2S atmosphere and caused decomposition of CdS back to their nitrates.

To overcome above problems, a polymerizing agent, such as titania or silica precursors have been added to salt/surfactant LLC mesophase. Both titania and silica overcame collapse of the mesophase by rigidifying the structure into mesostructured solid and also by providing stability for a thermal removal of nitrates from the media. For this investigation, both [Cd(H2O)4](NO3)2 and [Zn(H2O)6](NO3)2 salts and P123 ((PEO)20(PPO)70(PEO)20) and C12EO10-CTAB couple have been used. Well-ordered mesostructured Cd(II) titania films have been obtained up to 15.0 Cd(II)/P123 mole ratio for a 60 mole ratio of Ti(IV)/P123 by spin or dip coating of a mixture of 1-butanol-[Cd(H2O)4](NO3)2-P123-HNO3-Ti(OC4H9)4. Exposing the mesostructured Cd(II)-TiO2 films to H2Se under a N2 atmosphere gave stable CdSe nanoparticles in the channels of the mesostructured rigid titania walls up to 25 mole % Cd(II)/Ti(IV). To further increase the metal ion (Cd(II) and Zn(II)) content in the structure of the C12EO10-CTAB-salt mesophase have been employed. The two surfactant-salt systems, in the presence of a titania precursor, produced sponge like mesoporous CdTiO3 and Zn2TiO4 films up to a mole percent of 57 and 86, respectively, upon calcination. Exposing the mesoporous CdTiO3 to H2S or H2Se atmosphere at RT produced homogeneously distributed CdS or CdSe nanocrystallites on the nanocrystalline TiO2 pore walls, respectively. The reaction of mesoporous Zn2TiO4 with H2Se produced stable ZnSe nanocrystallites on the nanocrystalline TiO2 pore walls. The conversion of titania from CdTiO3 to an anatase and brookite phase under H2S and H2Se atmosphere, respectively, and from Zn2TiO4 to a rutile phase under H2Se were observed for the first time. Adding a silica precursor to the two surfactants (C12EO10-CTAB)-salt mesophase produced mesostructured salted-silica, and its calcination produced sponge-like mesoporous silica-metal oxide (dumped meso-SiO2-CdO and meso-SiO2-ZnO) thin films. Up to ~100 % and ~50 % surface coverage could be achieved by CdO and ZnO as nano-islands over the SiO2 pore walls. Exposing the mesoporous SiO2-CdO and SiO2-ZnO thin film precursors to H2S and H2Se at RT enabled the synthesis of mesoporous SiO2-CdS, SiO2-CdSe, SiO2-ZnS, and SiO2- ZnSe thin films. The MS or MSe nanoflakes could homogenously cover the pore walls of mesoporous silica by retaining the pore morphology of the MO precursors. Finally, the SiO2 walls were removed from the meso-SiO2-CdS and meso-SiO2-CdSe films through etching in a dilute HF solution to produce mesoporous CdS (meso-CdS) and mesoporous CdSe (meso-CdSe). Surface of the meso-CdS has been modified using PEI (polyethyleneimine) and photoluminescent meso-CdS were obtained.

It's no secret that the last five years have been good for the cannabis industry. Although legalization has yet to spread around the world, the stigma surrounding cannabis use has begun to shift towards a more widespread acceptance of the benefits of the plant. In Canada alone, the legal market is worth $ 5 billion by 2021, which is a conservative estimate, as Canada has one of the highest rates of cannabis use.Along with the myriad businesses riding this wave, so are the scientists. An innovation racehas been launched to explore the various applications of cannabis in health and wellness.While nanotechnology has been used in the food and medical industries for some time, its potential with cannabis is only just beginning to be explored.According to the Pot Network, cannabis, and other products in general, appears to work most effectively when broken down into tiny particles. When they break down, chronic pain patients, for example, may feel the first signs of relief within 15 minutes of absorption. This is due to the fact that the nanoparticles are directly absorbed into the bloodstream.This technology should continue to gain momentum in North America, with a population of more than 70 million postwar births that is aging. From cancer treatment to extended-release sleep aids, scientists are only scratching the surface of the potential of nanotechnology.Nanocann Group is one of those companies that is driving the cannabis market through the use of nanotechnology. Based in Mexico City, he's ready to take full advantage of the upcoming Mexican cannabis law.The company conducts research and manufactures nanotech encapsulates focused on the development of health-based CBD hemp consumer products in the nutraceutical, cosmetics, food and beverage sectors, as well as in the pet sectors around the world.

Title: Driving Molecular Transport across Biological Membranes from Magnetic Nanoparticle/Pulsed Magnetic Field



Our research aim is to investigate how magnetic nanoparticles and magnetic field combinations can be used to open up pores on various membranes to facilitate transport of various sized molecules. The research will address the underlying fundamental challenges that limit the efficient use of various types of magnetic fields for creating a biological response such as cell death, change in function. In this research, cell, bacterial and liposomal model systems will be investigated when nanoparticles are integrated into their structure and exposed to various types of magnetic fields such as short homogeneous and inhomogeneous magnetic pulses, linearly and circularly polarized magnetic fields, or small amplitude AC magnetic fields. The transport properties will be evaluated using fluorescence techniques based on permeability essays, electrochemical essays detecting small trace molecules and based on exploring the biological response of the system such as cell viability. Addition characterization techniques will be necessary to accurately survey the structure of these systems prior and post exposure to the magnetic fields. In this research, we will implement spectroscopic and microscopic techniques to explore spatial and dynamical aspects of the magnetic fields on proposed systems. Integration of fluorescence microscopy with electromagnet will allow studying the systems under the I influence of the magnetic fields. Spectroscopic method based on magnetic field transient Faraday rotation of the magnetic particles and dynamical measurements of ultrasonic intensities will explore the transfer of the magnetic field’s energy into mechanical movement in the medium.

Strategies to encapsulate actives,such as drugs or catalysts, and to fabricate hollow capsules have received considerable attention in research. Furthermore, the delivery,or release, of the trapped active is a key area of our research. We have developed a new hybrid capsuleproduction technique, where a multi-functional branched copolymer is exploitedas both emulsifier and cross-linker[1,2]. The strategy has the key advantages of: (i) being single component, (ii) producing stablecapsules and (iii) providing additional capsule surface chemistries by design.The capsule formation process both exploits and relies on polymer architecture and composition. The chosen architectureprovides stabilityand efficient surfactant properties[3]. Thecopolymercomposition provides extra stabilization and capsule-formation function. Thisstrategy provides a generic and translatable method for encapsulating hydrophobic materials and producing hollow capsules,which may have applications in catalysis, delivery and sensing devices.Product development has been conducted with tier 1 and 2 customers on the entrapment and release of drugs, dyes, fragrances, catalysts, and pesticides.In principle, the diversity of compositions accessed using thepolymer synthetic route providesa wealth of opportunity in terms of functionalizing the capsule surfaces. It is possible to hand-pick moieties and pre-determine the surface chemistry for tailored applications. This has been shown by tailoring the polymer to create stimuli-responsive capsulesand ‘burst-release’ breakable capsules, respectively. We also demonstrate how control over copolymer composition can direct theassembly of capsules into shapes or permanent porous scaffolds. Given this potential scope, we anticipate various applications of these materials inbroad research areasthatrequire encapsulation of actives for extended periods and functionalized capsule surfaces. There is massive commercial interest because of the use as a repository into which other materials can be put and protected. The applicability of design-led functional responsive polymers is key for many commercially relevant applications.

The cost of the production of carbon nanotubes (CNTs) is one of the great challenges. The pyrolysis is a simple and economic technique for synthesizing CNTs at low temperatures. Fabrication and characterization of CNTs using pyrolysis process and from environmentally green source (olive oil). The precursors, the catalyst, and the carrier gas affect the cost of production. The production of olive oil in Egypt, Middle East and gulf region dedicated them as a great production area for CNTs. olive oil is used as precursors and compared with nickel chloride (5 wt. %) as a catalyst and argon as a carrier gas. Si wafer has been used as a substrate and operated at 900 °C. The CNTs were characterized by FESEM (Field emission scanning electron microscope), HR-TEM (High Resolution Transmission Electron Microscopy), X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy. The results reveal that as-grown nanotubes are well graphitized with olive. CNTs were prepared by catalytic decomposition of the oil over the metal particles dispersed and supported on the substrate by pyrolysis method. The results illustrated that the different densities of the oils and ratios of saturated hydrocarbons in olive oil caused the production of different carbon products.

Supercritical fluids (SCFs) are the transient states of matter produced through operating the fluids above their critical point. SCF are inexpensive, non toxic, non flammable media with pressure tunable density, viscosity, diffusivity and surface tension. Density, viscosity and diffusivity are the common physical characteristics of SCFs that they share with liquids (Fig.1). High penetrating power of SCFs is due to their 102 to 103 times greater densities over liquids, 10 to 102 times reduced viscosities over gases and high rate of diffusion @ 10-3 to 10-4 cm2/s times over liquids. Such unique combinations of physical behavior SCFs are effused across solids leading to swelling or solubilzation 1. Among SCF, the most investigated are supercritical carbon dioxide (SCC) and supercritical water (SCW) [2-4]. Judicious variations in temperature and pressure equalizes the densities of liquid and gas phases, restricting phase transitions in SCFs regardless to applied pressure .Applications of SCFs as an alternative media in food processing , chromatography, energy production and drug development was recognized till beginning of 19th century, has now well accepted in processing of materials 6-13.SCFs offers a series of unique methods  of particle sizing,  development of polymer composites, blends, dispersion of layered silicate, inorganic4, graphitic and magnetic fillers  into solvents, monomers and their infusion into polymer matrix at ambient temperatures. Polymer functionalized nanostructurd polyelectrolytes for photovoltaic and energy storage applications are successfully synthesized under supercritically controlled conditions. Highly sensitive functional nanomaterials for antibacterial applications sensor and target delivery of drugs are conveniently synthesized in SCC7-13.The present talk, shall deliver the salient features of SCFs and their applications in particle fabrication, polymerization, preparation of nanocomposites, nanohybrids, nanomaterials for wood preservation, nanocomposites for development of durable composite structures, electroactive nanomaterials for sensing, energy storage, target delivery systems and nanoparticle mediated microbial degradation of commodity plastic materials. Concluding remarks will be presented on simplicity, diversity, and commercial viability of SCFs processing of polymer nanomaterials.

Title: Design, synthesis, and characterization of carbon-based nanocomposites with conducting polymers /metal oxides and their application


Dr. Amjad Mumtaz Khan joined Department of Chemistry, Aligarh Muslim University, India in 2011 on permanent position as Assistant Professor at a young age. His area of specialization is Analytical chemistry and research interest includes chromatography, development of new nano materials in environmental pollution control and drug delivery systems. He has published 23 research articles in high impact journals of international repute and also published 5 book chapters in international publications such as CRC Press and Apple Academic Press.



Currently the knowledge of low dimensional nanomaterial’s attains global consideration, due to their outstanding applications in various fields such as sustainable energy, electrocatalysis, sensors, waste water management, environmental and bio-medical fields to have pollution free environment. Thus, it becomes necessary to examine the potential of low cost and ecofriendly two-dimensional (2D) nanomaterials. These 2D nanomaterials include carbon nanotubes, graphene oxide, layered metal hydroxides (LMHs) [layered single metal hydroxides (LSHs) and layered double hydroxides (LDHs)], graphitic carbon nitride (g- C3N4), metal carbides, nitrides (MXenes) and single- or few-layered transition metal dichalcogenides (TMDs). Organic-inorganic hybrid materials combine the advantages of synergistic interactions from organic and inorganic precursors and possess promising application prospect. Layered double hydroxides (LDH’s) incorporated with carbon-based materials and other conducting polymers have been investigated due to their versatile and unique features.Carbon nanotubes (CNTs) provide a new model system for basic scientific study of material science. Substantive efforts have also been made to explore their applications. For example, CNTs have been used as nanofillers for preparing composite materials with enhanced mechanical and/or electrical properties, such as scanning probe tips, field emitters, diodes, quantum wires, support  for catalysts, electrodes and so on. The utilization of carbon nanotubes was based on their unique structure and excellent physical properties, such as their good mechanical properties, electrical properties, one dimensional nanostructure, even at times many of or all these properties as a whole. Modification of CNTs with functional materials will greatly broaden and enhance their applications. The preparation of hybrid materials, based on the combination of metal oxides/conducting polymers and CNTs possessing
the properties of each component, or even with a synergistic effect, would be useful in field emission displays, polymer or ceramic reinforcement, super capacitors, chemical sensors and drug delivery, biosensors, photocatalysts and electronic or photoelectrical devices. Furthermore, the use of biopolymers, polymers, metal oxides and carbon materials has been proposed for the preparation of innovative drug delivery devices. One of the most promising materials in this field are the carbon nanotube composites and hybrid materials coupling the advantages of polymers (biocompatibility and biodegradability) with those of carbon nanotubes (cellular uptake, stability, electromagnetic, and magnetic behavior). The CNT network has found to facilitate dispersion of the oxide nanoparticles because of their large surface and the ability to provide continuous conducting pathways for the transportation of electrons. These characteristics are beneficial for the applications of the hybrid materials of CNTs and metal oxides/conducting polymers.There have been some investigations concerning the attachment of various inorganic oxides onto single-walled carbon nanotubes (SWCNTs) and multiwalled carbon nanotubes (MWCNTs). For example, oxide nanoparticles such as SiO2, SnO2, ZnO, TiO2 in the presence of conducting polymers (polypyrrole, polyaniline, poly-o-Anisidine) have been coated onto CNTs by impregnation, sol–gel, hydrothermal synthesis, thermal evaporation-deposition and so on. In order to get strong combination and homogeneous distribution of oxide nanoparticles on functionalized CNT. Carbon supported nanomaterials possess high surface area, high conductivity, enhanced adsorption efficiency and thermal stability which makes the hybrid nanomaterials best candidates in catalysis, adsorption, drug delivery, photocatalysis, along with several other miscellaneous applications. Carbon based nanomaterials represent one of the most technologically promising areas. However, still, there are many challenges that must be sorted out to explore the potential of these nanomaterials in other fields. The first challenge related to graphene-based nanomaterials is the method of preparation to get uniform size distribution so that all the surface atoms are fully exposed to utilize the maximum surface area. The second challenge in graphene oxide nanomaterials is to improve the overall electrochemical performance due to synergistic effects. The electrochemical applications of graphene oxide can be enhanced by varying various factors such as changing the metal ions, varying bivalent to trivalent or tetravalent metal ion ratios, doping, use of other various conducting materials (CNTs, CNFs, Carbon dots). Another major challenge in this rapidly growing field is to improve the functionalities of carbon supported nanomaterials. In addition, we are also looking for future developments in the use of graphene- CNT based nanocomposites in catalysis.Currently we are working on synthesis, characterization and application of graphene, rGO, MWCNT, SWCNT, supported rare earth doped nanocomposites. These nanomaterials are evaluated in various applications like adsorption of heavy toxic metals from real water samples, photodegradation of toxic organic compounds and dyes present in waste water, Nano carriers for drug molecules, sensors for gases and liquids, supercapacitors.Adsorption of toxic heavy metals from waste water is our prime motive. But regeneration or recyclability of the adsorbent is still pending issue. From the literature the efficiency of the adsorbent is almost reduced to its half as compared to initial efficiency after ten or twenty cycles.
Leakage of dangerous gases either from industries or labs is very harmful to mankind, hence, there detection is of prime importance. Recently we synthesized novel nanomaterials which have shown excellent sensing properties for both gases as well as liquids.Using non-enzymatic biosensors which are economic instead of enzyme supported sensors is an emerging field of science and currently we are focusing in this area.Due to the conductive nature of conducting polymers and high specific area, we are designing our materials for supercapacitors which is also another blooming area.

Title: : Lignocellulose Application as Sustainable High-value materials


Innovator/entrepreneur in Catalysis, Renewables, New energy, CO2 reduction and Bio-materials space. Speaker and/or consultant on Innovation and R&D.


The challenge in biomass conversion is that the products produced are of low quality and therefore of low value and only utilizable in commodity areas like energy (i.e. replacing coal) and/or at best in transportation fuels (i.e. ethanol). In this paper a new low-cost technology is presented which is capable to fractionate the valuable constituents of biomass, being polymeric Cellulose and polyaromatic Lignin, without destroying or damaging these components. This is very unique and up to now has only been possible making use of enzymes or of high cost organic ionic liquid technology. The Nano cellulose and Lignin produced are suitable candidates and/or precursors to produce high performance fibers like super nanocellulosic fibers and Carbon-fibers. Materials and Methods Based on the unique ionic-liquid like” properties of ZnCl2 solvents a novel cost-effective technology has been developed to convert cellulosic wastes into high quality materials such as tailored micro and Nano cellulosic materials. The original intention of this technology was to convert cellulosic wastes into sugars which could serve as base materials for the production of renewable fuels. During the development of such a route it was found that the cellulose produced from raw materials was quite unique and exhibited special properties and based on this insight the technology was adapted with the aim of producing valuable bio-based materials. The advantages of this technology versus alternative routes as for instance the conversion of cellulose by enzymes, acids, organic ionic liquids and/or in combination with high energy mechanical milling are discussed. Biomass conversion with acids is fast but produces a lot of degraded side products. The use of ionic liquids and/or enzymes is expensive and slow (10-40 hours). With this improved ZnCl2 hydrate technology the opportunity arises to economically produce various high value products such as: • Micro and Nano-Cellulose applied as bio-coatings & materials. • Cellulose oligomers in food applications (non-digestible fibers). • Lignin and Nano-Cellulose as construction materials (High Tech Wood) • Lignin for Bio-Aromatics (precursors for Surfactants and Carbon Fibers) • Lignin as bio-component in polymeric materials. The Nano cellulose and Lignin produced are suitable candidates and/or precursors to produce high performance fibers like super nano-cellulosic fibers and Carbon-fibers. The economic value of these materials is at least 5-10 x higher than the commodities produced with other biomass conversion technologies.Based on these characteristics it is possible to establish a very attractive business case for the utilization of biomass and biomass waste components as high value materials.

Title: Tissue engineering and three-dimensional printing in periodontal regeneration: a literature review


Simon Raveau currently works in a dental pratice in Saint Molf (44350) in France. Simon works in Aesthetic Dentistry, Periodontology and Dental Surgery. His current project is '3D printing in periodontology'.


The three-dimensional printing of scaffolds is an interesting alternative to the traditional techniques of periodontal regeneration. This technique uses computer assisted design and manufacturing after CT scan. After 3D modelling, individualized scaffolds are printed by extrusion, selective laser sintering, stereolithography, or powder bed inkjet printing. These scaffolds can be made of one or several materials such as natural polymers, synthetic polymers, or bioceramics. They can be monophasic or multiphasic and tend to recreate the architectural structure of the periodontal tissue. In order to enhance the bioactivity and have a higher regeneration, the scaffolds can be embedded with stem cells and/or growth factors. This new technique could enhance a complete periodontal regeneration. This review summarizes the application of 3D printed scaffolds in periodontal regeneration. The process, the materials and designs, the key advantages and prospects of 3D bioprinting are highlighted, providing new ideas for tissue regeneration.

Title:  Modified Activation Process for Supercapacitor Electrode Materials from African Maize Cob






bstractIn this work, African maize cobs (AMC) were used as a rich biomass precursor to synthesize carbon materialthrough a chemical activation process for application in electrochemical energy storage devices. The carbonization and activation were carried out with concentrated Sulphuric acid at three different temperatures of 600, 700 and 800 °C, respectively. The activated carbon exhibited excellent microporous and mesoporous structure with a specific surface area that ranges between 30 and 254 m2·g1as measured by BET analysis. The morphology and structure of the produced materials are analyzed through Field Emission Scanning Electron Microscopy (FESEM), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Boehm titration, X-ray Photoelectron Spectroscopy (XPS) and Raman Spectroscopy. X-ray photoelectron spectroscopy indicates that a considerable amount of oxygen is present in the materials. The functional groups in the activated carbon enhanced the electrochemical performance and improved the material’s double-layer capacitance. The carbonized composite activated at 700 °C exhibited excellent capacitance of 456 F g1at a specific current of 0.25 A g1in 6 M KOH electrolyte and showed excellent stability after 10,000 cycles. Besides being a low cost, the produced materials offer good stability and electrochemical properties, making them suitablefor supercapacitor applications.

His current research focus is centered around developing modular organ-on-a-chip and body-on-a-chip systems for drug discovery and disease modeling.




Organ-on-a-chip (OOC) is an ambitious emerging technology with a great potential to enable in-depth studies of disease pathogenesis and therapy, hence opening new avenues for drug discovery, toxicology, and personalized medicine and offer a reliable alternative to animal models. In vivo, the organ(s) function is orchestrated by complex cellular structure and physiochemical factors within the Extracellular Matrix and secreted by various cells. Microfabrication and microfluidics technologies provide tools to create advanced cell culture systems, which can be employed to create in vivo-like cellular microenvironments and recapitulate specific tissue structure and physiological parameters. Here we will describe a compartmentalized microfluidic system for OOC that enables co-culturing of several cell types in close proximity with enhanced cell-cell interaction. We will then discuss three immune-competent micro-physiological models, namely the human gastrointestinal tract, the human epidermis, and the adipose tissue, the interaction of immune cells with these tissues, and their role in inflammation. We will emphasize the interaction between the adipocytes and immune cells to highlight the role of immune cell infiltration in the adipose tissue in the pathogenesis of diabetes type 2.

Andrea Paris is a student at Cardiff University on her final year of a Chemistry with Integrated Masters degree. Currently working in Cardiff Catalysis Institute, she has also undertaken placements in KU Leuven (2018), Yonsei University (2019) and Nanyang Technological University (2019-2020).



Understanding the interactions between polymers and surfaces is very important for the development of new, more effective materials such as glues and coating agents. The aim of this paper is to study the adsorption of polystyrene on model silicon surfaces and determine the extent to which the surface functionalisation influences the styrene adsorption. Different surface-modified silicon wafers were spin coated with layers of polystyrene. The functionalised surfaces studied included samples with terminating amine, methyl, thiol and hydroxyl groups with a hydrogen terminated silicon surface on which no hydrogen bonding could occur used as a control sample.


X-ray photoelectron spectroscopy (XPS) of the C1s shake-up satellites, which arise from π-π* transition of the aromatic ring of the polymer, was used to provide information on the nature of the interactions between the polymer and the functionalised silicon surfaces, with DFT modelling performed to establish a realistic model of the electronic structure of the adsorbed polystyrene’s MO energies.

Title: Molecular Dynamics Simulation Insight into Water Condensation as a Function of Surface Hydrophobicity


Dineli T. S. Ranthunga is a young scientist with a PhD in computational chemistry from the University of Texas at Dallas, USA. Her doctoral work mainly explores the applications of molecular modeling techniques to understand the molecular behavior of mechanically and biologically important surfaces.During her PhD, she published more than 8 articles and has beenserving asa peer reviewer in reputed journals. Before obtaining her PhD, she received a BSc in Chemistry (2014) from the University of Peradeniya, Sri Lanka and a Bachelor of Information Technology (2105) from the University of Colombo, Sri Lanka.From 2014 to 2016 she worked as a quality assurance analyst / tiger brewer at Heineken, Sri Lanka.


Water condensation plays a major role in a wide range of industrial applications. Over the past few years, many studies haveshown interest in designing surfaces with enhanced water condensation and removal properties; lotus leaf-like super-hydrophobic surfaces (SHS) and hydrophilic directional slippery rough surfaces (SRS) are some of the examples. To advance these designs a molecular scale understanding of the water behavior as a function of surface hydrophobicity is strongly needed. Since the approaches to quantify wetting at the macroscale do not always translate to the nanoscale, there is a need for new methods to characterize hydrophobicity at small scale. Using molecular dynamics computer simulations of well-characterized alkanethiol self-assembled monolayers with different head group chemistries, here we quantify the role of surface hydrophobicity on water condensation. We measured the water condensation rates on different surfaces and linked that behavior to well established surface characteristics to give a more complete picture of the role of surface hydrophobicity on the behavior of water. We showed that using our techniques, even small changes in the surface hydrophobicity are readily apparent. We also observed a remarkable correlation between our results and the role of surface hydrophobicity on the water compressibility, interfacial thermal conductance and contact angle when we compare data across different studies. Examining the total interaction energy between water and the surface, density fluctuations near the surface, the formation, growth mechanism and stability of water clusters, and the wetting process on thesurface we are able to provide insight into the water condensation process on different surfaces as a function of surface hydrophobicity.
