Modulating the Near Infrared Reflective Properties of Metal Oxides for Surface Coating Applications

Nidhin M., Sangeetha S., Radhika S., Sreeram K.J., Nair B.U., Central Leather Research Institute (CSIR), IN

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 [...]

Self Healing Hybrid Coating for Aggressive Environment

Vashisth C., Potrekar R., Roy Choudhury N., Dutta N.K., University of South Australia, AU

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 [...]

Solution Growth of Nanostructured Ceramic Films

Cho J., State Univ of New York (SUNY) at Binghamton, US

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 [...]

Design Parameters for “Robust” Superoleophobicity Surfaces

Law K-Y, Zhao H., Park K.C., Xerox Corporation, US

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 [...]

Growth of ZnO Nanorods in Clay Matrix to Ensure Uniform Dispersion in Drilling Fluids

Abdo J., Haneef D., Sultan Qaboos University, OM

The rheology of drilling fluids plays an important role in controlling drilling operations. The use of modern equipment and most updated technology is wasted if it is not complimented by a compatible drilling fluid. Severe [...]

Optical Trapping of Gold-Coated Liposomes

Leung S.J., Romanowski M., University of Arizona, US

We recently introduced a nanocomposite material, plasmon resonant gold-coated liposomes, to address unmet needs in area of controlled delivery. Plasmon resonant nanocapsules are created via the deposition of gold onto the surface of 100 nm [...]

Stimuli-responsive nanogels by e-beam irradiation of dilute aqueous micellar solutions: Nanogels with pH controlled LCST

Picos-Corrales L.A., Licea-Claveríe A., Arndt K.-F., Instituto Tecnologico de Tijuana, MX

Nanogels have attracted growing interest owing to their potential for applications in drug delivery systems. In this work, responsive nanogels based on amphiphilic block copolymers crosslinked in the micellar state were prepared by electron beam [...]

Synthesis, characterization and viscoelastic properties of Nanocrystalline Cellulose grafted with Poly(N-isopropylacrylamide)

Hemraz U.D., Danumah C., Lu A., Boluk Y., National Institute for Nanotechnology, University of Alberta, CA

Nanocrystalline cellulose (NCC) is a renewable, nontoxic and biodegradable nanomaterial that can be obtained by acid hydrolysis of the amorphous regions of the widely available cellulose. The relative low density, low cost, high aspect ratios, [...]

Polymer Nanomanufacturing Strategies for Multifunctional Nanomaterials

Mead J., Barry C., Wei M., Busnaina A.A., University of Massachusetts-Lowell, US

Polymeric materials offer tremendous potential for preparing functional materials using nanoscale fillers and features. For example, the use of nanolayered materials in barrier or optical applications, nanofeatured materials for hydrophobic surfaces, and patterned polymer blends [...]

Electrosynthesis of Intrinsically Conducting Polymers/Silicon Nanocomposites: Formation Mechanism and Optical Properties

Harraz F.A., Salem A.M., Central Metallurgical R&D Institute (CMRDI), EG

When a silicon wafer is subjected to electrochemical etching in fluoride-based solution, silicon surface develops pores, often called porous silicon (PSi). A variety of pore sizes ranging from a few nanometers up to a few [...]
