Recent advances in the use of plasmonic metamaterials to improve absorption of light in thin-film solar photovoltaic devices has created a demand for a scalable method of patterning large areas with metal nanostructures deposited in an ordered array. This article describes two methods of fabricating ordered 2D nanosphere colloidal films: spin coating and interface coating. The two methods are c...

In this study, Damar Batu (DB) − a novel biomaterial− is evaluated for its potential application in pharmaceutical coating. DB is a whitish to yellowish resin, characterized initially in terms of solubility, acid value, molecular weight (Mw), polydispersity index (Mw/Mn) and glass transition temperature (Tg). Neat plasticized films of DB are investigated for mechanical, water vapor transmission...

Specific members of the intestinal microbiota dramatically affect inflammatory bowel disease (IBD) in mice. In humans, however, identifying bacteria that preferentially affect disease susceptibility and severity remains a major challenge. Here, we used flow-cytometry-based bacterial cell sorting and 16S sequencing to characterize taxa-specific coating of the intestinal microbiota with immunoglo...

We developed a paper coating for the potential application in food packaging based on polylactide and montmorillonite. It is applied to the paper in the form of a stable, water-based latex with a solid content of 25–28 wt %. The latex is prepared from a commercially available polylactide, surfactants, montmorillonite, a plasticizer, chloroform (to be removed later) and water by an emulsion/solv...

Objective: In the present work, strontium (Sr) was incorporated into TiO2 (Sr-TiO2) coatings on titanium by Micro-arc oxidation (MAO) technique in the Ca, P, Sicontaining electrolyte to obtain the implant with good bioactivity. Methods: The surface topography, phase and element composition were characterized by scanning electron microscopy, X-ray diffraction and energy dispersive spectrometer, ...

Large area, fullerene-free organic solar cells with improved stability and efficiency of up to 1% are fabricated by the roll-coating process on indium tin oxide free and flexible substrates, under ambient conditions.

A new window coating system has been developed to coat a newly designed window for the Storage Ring RF System in the Advanced Light Source(ALS). A bell jar large enough to accommodate the 15cm (OD) x 50cm (L) tubular ceramic window is used for a vacuum chamber. Methodical procedures are employed to ensure the chamber is free of contaminants before any coating is carried out. A single filament i...

In hot dip galvanizing, several parameters such as chemical composition of coating bath, immersion time and surface roughness of specimens could affect microstructure and properties of coating. In this article, the effect of aluminum content, immersion time and surface roughness on structure and properties of alloy layers have been investigated. Specimens of low carbon silicon-free steel with d...

In order to avoid undesired effects from vortices in many industrial processes, it is important to know the set of operating parameters at which the flow does not have recirculation. The map of these conditions in the parameter space is called vortex-free operating window. Here, we propose an efficient way to construct such window automatically without expensively checking every possible flow s...
