Abstract Hydrogel is a 3D framework of hydrophilic polymeric material that quickly absorbs and retains huge amount water (or other fluid) offers versatile functionality. A series unique carboxymethyl cellulose/Xanthan gum/polyvinyl alcohol (CXP) blended hydrogels, containing both the natural synthetic polymers, were prepared by following blending casting approach. The polymers incorporated thro...

The application of biodegradable chitosan fiber for healthy and hygienic textiles is limited due to its poor acid resistance in wet processing and poor antioxidant activity. In order to prepare chitosan fiber with good acid resistance and high antioxidant activity, chitosan fiber was first crosslinked by a water-soluble aziridine crosslinker, and then dyed with natural lac dye consisting of pol...

A chrome gel system with 13 million molecular weight and 19 polymer DQ-8 cross-linking agent is dynamically gelled under different conditions of 50-mesh 100-mesh screens shear rates. Concentration limit. The experiment shows that the critical concentration gelation 500-700mg/L, new in 80mg/L-90mg/L. cross-linker cut by steel mesh. post-gelation time prolonged. Between 6h-10h, after 12 days test...

Poly(N-isopropylacrylamide) microgel particles are synthesized using a semi-batch surfactant-free emulsion polymerization method. Particle diameter can be precisely adjusted by controlling the initial conditions, the electrolyte concentration, and the monomer feeding rate and duration. Larger particles are obtained in the presence of small amounts of co-monomer with cationic amino groups that c...

Gas chromatography (GC) is considered the least common application of both polymer and silica-based monolithic columns. This study describes the fabrication of alkyl methacrylate monolithic materials for use as stationary phases in capillary gas chromatography. Following the deactivation of the capillary surface with 3-(trimethoxysilyl)propyl methacrylate (TMSM), the monoliths were formed by th...

Molecular chaperones, suchas the small heat shockproteins (sHsps), maintain normal cellular function by controlling protein homeostasis in stress conditions. However, sHsps are not only activated in response to environmental insults, but also exert developmental and tissuespecific functions that aremuch less known.Here,weshow that during normal development the Drosophila sHsp CryAB [L(2)efl] is...
