Earlier we reported the fabrication of a model superoleophobic surface comprising ~3-micron diameter pillar arrays on Silicon. Results showed that both surface fluorination and the re-entrant geometry are crucial in achieving the superoleophobicity with hexadecane [...]
Low-temperature processing that can lead to the development of highly-functional, strain-tolerant ceramic films will offer innovative solutions for the use of ceramic thin films and coatings. Current developments in organic and flexible electronics make the [...]
Self healing is a desirable property of a coating on metallic substrate to help arrest the development of micro-cracks and the propagation of corrosive species to the interfacial layer and eventually to the substrate. While [...]
A colorant which is able to reflect a major portion of the near infrared radiation is today known as cool colorant. These colorants when coated on roof tops, automobiles, leather etc. reduce the demand for [...]
Nano-cluster formation of Platinum (Pt) on a modified K-OMS-2 manganese oxide inorganic paper by reactive spray deposition technology (RSDT) is presented. RSDT was employed to produce a film on the inorganic K-OMS-2 paper material. The [...]
We report on the synthesis of AlN hollow nanofibers by plasma-enhanced atomic layer deposition (PEALD) using electrospun polymeric nanofibers as templates. Three templates with different average fiber diameters were obtained by electrospinning of polymeric solutions [...]
We tested and characterized molecular coating of Aluminium and Nickel prototype molds and mold inserts for polymer replication via injection molding (IM). X-Ray photoelectron spectroscopy (XPS) data, sessile drop contact angles with multiple fluids, surface [...]
This work focuses on understanding the effects that nanotopology has on protein adsorption. Functionalized block copolymers were synthesized and processed to produced highly ordered, nanopattered films. Experiments utilizing a quart crystal microbalance were completed to [...]
We report on the fabrication of organic-inorganic core-shell nanofibers by using two-step approach; electrospinning and atomic layer deposition (ALD). In the first step, nylon (polymeric organic core) nanofibers having different average fiber diameters were electrospun [...]
Recently, we used the broadband dielectric spectroscopy (BDS), from low (a few Hz) to microwave (a few GHz) frequencies. This technique is very sensitive to the different scales of the electrode architecture involved in the [...]
Layer by layer assembly is a powerful nanotechnology thin film deposition process that enables the creation of highly uniform multilayer optical films. Svaya is using this technology to create highly reflective UV, Visible and IR [...]
The goals of this work were to decrease the synthesis temperature of CCTO thin films using the pressure method, and to improve the homogeneity and density of the CCTO films in order to obtain better [...]
Transparent electrodes are critical components of optoelectronic devices such as solar cells, organic light-emitting diodes, and displays. Most high-performance transparent conducting films at present are composed of sputtered metal oxides, which have limited flexibility because [...]

A new clay polymer composite film was prepared by mixing specially processed non-swelling clay and polyimide at an optimal ratio. The newly developed film (80 µm thick) was heat-resistant at 450°C and showed very little [...]
Both surface topographical and chemical composition of nanoparticle coated paperboard was characterized to explain observed differences in surface wettability. TiO2 particles induce superhydrophobicity with water contact angle (CA) of 161° whereas SiO2 particles result in [...]
Recently, researchers introduced a new technique to fabricate superhydrophobic coatings by spray-casting polymer-nanoparticle suspensions using an air-atomizing nozzle. Upon thermosetting, the deposited polymer networks crosslink to form a durable, superhydrophobic nanocomposite coating. However, while the [...]
The following abstract investigates superhydrophobic nanocomposite surfaces that are continuously submerged in water. Unfortunately, the surfaces lose superhydrophobic functionality under constant contact with water. Until recently, there has been little analysis on this performance behavior. [...]
The Lotus effect is used as inspiration for the fabrication of injection molded (IM) hierarchical polymer surfaces with self-cleaning properties. IM is a widespread method for the fabrication of plastic items. Surface functionalization is traditionally [...]
One of the recurring problems with hearing aids is the frequent exposure to moisture, wax and other foreign materials that can degrade and eventually hinder their performance. This issue may be exacerbated as the demographics [...]
The objective of this study was to test the mechanical durability of a polyurethane/organoclay nanocomposite modified with perfluoroalkyl methacrylic copolymer in conditions that replicate extended rain impact. Samples were impacted with 1.4 mm droplets at [...]
