The increasing level of carbon dioxide (CO2) in the atmosphere is a big threat to the environment and plays a key role towards global warming and climate change. In this context to combat such issues, polymeric ionic liquids (PILs) serve as potential substitutes that offer an extremely versatile and tunable platform to fabricate a wide variety of sorbents for CO2 capture, in particular, for flu...

Macromolecular or polymeric liquids consist of polymer solutions, polymer melts, particle suspension fluids, and many biological fluids. Polymer solutions are made of polymers dissolved in solutions or solvent; polymer melts are molten polymers; particle suspension fluids consist of solid particles suspended in a matrix fluid which may be a viscous or viscoelastic fluid, blood flows consist of ...

The subject of polymeric drugs has recently achieved wide attention and is discussed anlong scientists interested in macrbmolecular science and in biological and pharmaceutical disciplines1). The general concept is also penetrating into regulatory authorities responsible for administering the areas of food and drng related subjects'. W e are limiting our discussion on polymeric drugs to materia...

This review accounts the various polymeric membranes available for use in fuel cells, advantages of sulphonation of polymers, various sulphonation methods and the characterization techniques. Presently, SPEEK finds extensive application as polymeric membrane in fuel cells. The adva...

Nanofilled polymeric matrices have demonstrated remarkable mechanical, electrical, and thermal properties. In this article we review the processing of carbon nanotube, graphene, and clay montmorillonite platelet as potential nanofillers to form nanocomposites. The various functionalization techniques of modifying the nanofillers to enable interaction with polymers are summarized. The importance...

canister desorption is a widely used technique to measure the gas content of coal. the gas content data, when normalized to volume/weight and multiplied by coal seam mass, is used to estimate the gas in place in an area around the cored hole. however, the gas content and the percentage of each constituent are likely to be influenced by trapped air in the canister at the time of the coal enclosu...

The formation of polymeric micelles by the self-association of diblock copolymers consisting of hydrophilic and hydrophobic segments in aqueous medium is currently a topic of great interest. This interest is motivated by the attractive applications of polymeric micelles to various research areas such as drug delivery carrier technology and nanotechnology. In the biomedical materials field, poly...

Many studies suggest that mutagenic/carcinogenic chemicals in the diet, like 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), may play a role in human cancer initiation. We have developed a method to quantify PhIP metabolites in human urine and have applied it to samples from female volunteers who had eaten a meal of cooked chicken. For this analysis, urine samples (5 ml) were spiked wit...

seven caspian miniature horses, aged above two years, were used for this study. the skeleton of these horses were cleaned and prepared using appropriate techniques. the vertebral column was studied and photographed. the vertebral column in one of these horses showed variations in thoracic, lumbar and sacral region. the vertebral formola was c7, t19,l5,s6 and a pair of 19th rib was fused with th...
