Abstract (sommario):

Biodegradable polymers are an exceptional class of polymers that can be decomposed by bacteria. They have received significant interest from researchers in several fields. Besides this, biodegradable polymers can also be incorporated with fillers to fabricate biodegradable polymer composites. Recently, a variety of ionic liquids have also been applied in the fabrication of the polymer composites. In this brief review, two types of fillers that are utilized for the fabrication of biodegradable polymer composites, specifically organic fillers and inorganic fillers, are described. Three types of

Abstract (sommario):

The paper investigates the theory of electrical breakdown channel formation in polymeric dielectrics. The process of operating electrical networks is quite complex, since dielectric materials lose their insulating properties under the influence of electric field intensity, which causes the destruction of molecular bonds. This phenomenon is called dielectric breakdown, or a violation of its electrical strength and loss of dielectric properties, followed by the formation of a breakdown channel with high electrical conductivity. Additional factors, such as insulation cooling conditions, external

Sludge surfaces were examined using transmission electron microscopy. The presence of CF indicates an anionic site not attached to polymers. For increasing polymer molecular weight, comparison of micrographs of samples conditioned with similar polymer doses showed an increase in CF attachment. Therefore

Abstract (sommario):

Polymers are a class of materials widely used in different fields of applications. With imminent applications of polymers, the study of radiation induced changes in polymers has become an obvious scientific demand. The bombardment by ion beam radiations has become one of the most promising techniques in present day polymer research. When the polymers are irradiated, a variety of physical and chemical changes takes place due to energy deposition of the radiation in the polymer matrix. Scissoring, cross-linking, recombination, radical decomposition, etc. are some of the interesting changes that

Abstract (sommario):

To obtain high ambient ionic conductivity of solid polymer electrolyte (SPE), we introduce polymer-in-salt system with ion hopping mechanism contrary to traditional salt-in-polymer system with segmental motion mechanism. In polymer-in-salt system, the interaction between polymer and salt is important because polymer-in-salt electrolyte contains a large amount of salt. Thus, we try to solve the origin of interaction between polymer and salt by using hard/soft acid base (HSAB) principle. The SPEs are made up of two types of polymers (poly(ethylene oxide) (PEO, hard base) and poly(ethylene imine)

Abstract (sommario):

In this study, the fundamental and spalling properties of high-strength concrete were examined, especially when various types and varying content of polymer resin were added. Two types of polymers were used in this study: ethylene vinyl acetate copolymer (EVA-P) and polyvinyl acetate copolymer (PVA-P) as powders and polyvinyl acetate copolymer (PVA-F) and polypropylene copolymer (PP-F) as fibers. Test results showed that the addition of EVA-P and PVA-F to concrete slightly decreased flowability, whereas the addition of PP-F and PVA-P enhanced the viscosity, leading to a remarkable reduction in

Chemical crosslinker polymer gels were synthesized in situ polymerization of monomers in solvents with crosslinkers. Results showed that the solvent content of the polymer gels depended on the types of solvents and polymers as well as the crosslinkers. The adsorption ability to aromatic organic molecules of the polymer gels was measured by treating tryptophan solution containing phenol and pyrene aqueous solution. The aromatic compounds can be removed completely and no further pollution to the original solutions.

Their physicochemical and X-ray attenuation properties were characterized. All polymer-coated Pt-NPs had an average particle diameter (davg) of 2.0 nm. Polymers grafted onto Pt-NP surfaces exhibited excellent colloidal stability (i.e., no precipitation after synthesis for >1.5 years) and low cellular toxicity. The X-ray attenuatio

Abstract (sommario):

A total of nine polymers were first tested. Correlations between molecular weight and sludge settling rate were identified for three types of polymers with a general trend of higher molecular weight giving a faster settling rate. Among the non-ionic polymers, the medium molecular weight polymer produced the best results (1831.88 ppm). Among the cationic flocculants, the lowest molecular weight polymer resulted in more REEs distribution (2478.81 ppm). It was concluded that the super high molecular weight of anionic flocculants works best for treating phosphoric acid sludge which resulted in REE
