A novel composite hydrogel was prepared via UV irradiation copolymerization of acrylic acid and maize bran (MB) in the presence initiator (2,2-dimethoxy-2-phenylacetophenone ammonium persulfate) cross-linker (N,N′-methylenebis(acrylamide)). Under optimized conditions, bran–poly(acrylic acid) obtained (2507 g g–1 distilled water 658 0.9 wt % NaCl solution). Effects granularity, salt concentration, various cations anions on absorbency were investigated. It found that swelling extremely...

In this paper, anhydrous pyrolysis experiments were performed on Huadian oil shale kerogen with and without different minerals (calcite, kaolinite, gypsum, montmorillonite) using a Fischer assay retorting system. The effect of mineral matrixes the formation was investigated, their catalytic activities obtained through experiments. Because strong activity, montmorillonite gypsum promoted products minimized residue products. Kerogen or kaolinite tends to direct generated hydrocarbons from into...

Abstract The photo‐assisted strategy is regarded as a crucial approach to enhance the conversion kinetics of polysulfides in lithium–sulfur (Li–S) batteries. However, development Li–S batteries still faces important challenges, such rapid recombination photogenerated electron−holes on cathode and more severe shuttle effect. Herein, breakthrough overcoming challenges has been made by constructing promising Li−S battery based semiconducted metal−organic frameworks. During discharging progress,...

Background Small cell carcinoma of the esophagus (SCCE) is a rare form esophageal cancer, which also belongs to category neuroendocrine malignant tumors, with low incidence but high aggressiveness, and very poor prognosis for patients. Currently, there lack unique staging treatment guidelines SCCE. Therefore, deeper understanding therapeutic targets mechanisms underlying its occurrence development great importance early diagnosis, identification potential agents improvement Methods Firstly,...

Abstract A simple procedure is reported for the fabrication of TiO 2 nanofibers via electrospinning technique using polylactic acid (PLA), tetrabutyl titanate, and hexafluoroisopropanol as a spinning solution. (600–700 nm in diameter), with bundled nanofibrils align fiber direction, are obtained from calcination as‐spun /PLA composite at 550°C. The structure physicochemical property generated elucidated by Fourier transform‐Infrared radiation spectrometer, X‐ray diffraction, scanning...

ABSTRACT A novel superabsorbent polymer composite was successfully synthesized from waste material cultured Auricularia auricula (WMCAA) and poly (acrylic acid ‐co‐ acrylamide) (P(AA AM)) using microwave irradiation. Optimal synthesis conditions were determined by investigating the water absorbency of composite. The effects associated with weight ratios WMCAA, acrylamide (AM) monomers, initiators, acrylic (AA) crosslinkers, as well degree neutralization AA examined. maximum absorbencies...
