Microwave assisted preparation and characterization of
It means that a high molecular weight polymer material can be grafted onto an active site, such as polyacrylamide (PAM), to enhance its flocculation performance [14,15]. It is well known that the sludge colloid has a negative charge. The cationic polyacrylamide (CPAM) flocculant is positively charged and is suitable for charge neutralization.

Hydrogel: Preparation, characterization, and applications: A
Bulk polymerization is the simplest technique which involves only monomer and monomer-soluble initiators. High rate of polymerization and degree of polymerization occur because of the high concentration of monomer. However, the viscosity of reaction increases markedly with the conversion which generates the heat during polymerization.

Green modification of surface characteristics of cellulosic
Abstract. Many current and potential uses of cellulosic materials depend critically on the character of their surfaces. This review of the scientific literature considers both well-established and emerging strategies to change the outermost surfaces of cellulosic fibers or films not only in terms of chemical composition, but also in terms of outcomes such as wettability, friction, and adhesion.

responsible for price increase. This could be a limitation for large-scale development of Li-ion batteries, which explains the recent interest for Na-ion and K-ion batteries. Graphite is the most widely used anode material for Li-ion batteries, but its specific capacity (372 mAh g-1) could be a limitation for high energy density batteries.

Treatment of the oil sands tailings using pure anionic polyacrylamide showed relatively high initial settling rate (ISR) of ~10.3m/h but with poor supernatant clarity (>1000NTU); while the treatment using pure cationic polymer resulted in clear supernatant (turbidity as low as 22NTU) but relatively low ISR of >2m/h.

The materials have high light transmittance (>95%) in the visible light region, high thermal stability and tunable refractive index (1.6533–1.8145) at 486 nm. Our study provides a new ideal for preparing high refractive index UV-cured titanium hybrid optical materials for potential optical applications. (Source: Materials Letters)
