China) Abstract: The microencapsulated display device is the main choice for electrophoretic display. The application of environment friendly dispersion medium is very critical for the commercialization of this technology. The electrophoretic microcapsules using Isopar L, which is non-toxic, low aromatic concentration and volatility, as dispersion medium were prepared by complex coacervation be...

Thermoelectric materials convert a temperature difference into electricity and vice versa. Such materials utilize the Seebeck effect for power generation and the Peltier effect for cooling. In the Seebeck effect, a temperature difference across a material causes the diffusion of charged carriers across that gradient, thus creating a voltage difference between the hot and cold ends of the materi...

Single crystal copper oxide nanoplatelets with a high percentage of {001} facets were synthesized by a facile hydrothermal approach. The as-prepared materials were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, field emission scanning electron microscopy, and high resolution transmission microscopy. Via density functional theory calculations, it was found that the ...

A chitosan from biologically obtained chitin was successfully grafted with d,l-lactic acid (LA) in aqueous media using p-toluenesulfonic acid as catalyst to obtain a non-toxic, biodegradable packaging material that was characterized using scanning electron microscopy, water vapor permeability, and relative humidity (RH) losses. Additionally, the grafting in chitosan with LA produced films with ...

A Novel approach to remove metals from aqueous solutions has been developed. The method is based on a resin free, solid, non-toxic, microcrystalline bisphosphonate material, which has very low solubility in water (59 mg/l to ion free Milli-Q water and 13 mg/l to 3.5% NaCl solution). The material has been produced almost quantitatively on a 1 kg scale (it has been prepared also on a pilot scale,...

Quest for newer material are never ending especially in the field of dental science. Various materials have been formulated, tested, and standardised to obtain maximum benefits for good clinical performance .One such new material which was introduced is Biodentine which has numerous clinical applications. An ideal orthograde or retrograde filling material should seal the pathways of communicati...

Introduction: Nowadays, advancements in industries, technology and human welfare level have lead to accumulation of solid wastes and have endangered environmental health. Incorrect waste management intensifies this problem. Recycling and composting (transformation of organic waste to humus) are the most important ways in waste management. Health and safety of the compost is an important issue b...

the synthesis of nano- structured cobalt through a controlled chemical process followed by heat treating at various temperatures is studied. the product is characterized by icp, xrd, fesem , and tem, indicating that the as- synthesized particles have an amorphous structure with 1.76 for co/b ratio, an average size of 50 nm. the transformation of intermediate phases into single phase nano- cryst...
