Novel mechanically strong and lightweight cellulose aerogels were successfully prepared by the procedures in four steps: (1) dissolving bamboo fiber in a mild NaOH/PEG solution; (2) freeze-thaw treatment; (3) regeneration; (4) freeze drying. The aerogels with dense interconnected and hierarchical...
A novel solid-solid phase change materials with polyethylene glycol (PEG) worked as phase change substance and polyacrylamide (PAM) as solid skeleton was s... XM Zhou - 《Journal of Applied Polymer Science》 被引量: 7发表: 2010年 Solution Drying and Phase Separation Morphology of Polyacrylamide...
The purpose of this work was to improve the stability of liposome by coating PEG.The vitamin C-containing liposome,which had been prepared by film dispersion-ultrasonic emulsify method,was coated with PEG by simply mixing the liposomal suspension with the PEG solution.The structure determined by el...
Preparation and Controlled Drug Release Characteristics of Thermoresponsive PEG/Poly (NIPAM-co-AMPS) Hydrogels Thermosensitive hydrogels were prepared by free radical polymerization of N-isopropylacrylamide (NIPAM) and 2-acrylamido-2-methylpropanesulphonic acid (AMP...

A Prospective Comparison of Sulfate Free Polyethylene Glycol versus Sodium Phosphate Solution for Precolonoscopic Bowel Preparation Background/Aims: Polyethylene glycol (PEG) solution is commonly used for precolonoscopic preparation because of its safety and effectiveness. Sulfate free PEG (SF-PEG) solution...
MATERIALS AND METHODS: The PGN dispersions were manufactured using three selected excipients: polyethylene glycol (PEG) 400/4000 (50:50), Gelucire 44/14 and D-±-tocopheryl PEG 1000 succinate (TPGS). Semisolid dispersions of PGN prepared by PGSS method were compared to the conventional methods;...
Background and study aims:Polyethylene glycol-based electrolyte solutions (PEG-ELS) and the combination of sodium picosulfate/magnesium citrate (SPMC) are commonly used bowel preparation agents. The aim of the present study was to compare the two agents with regard to cleansing efficacy and tolerance...
A casting solution was comprised of PVA, nano-SiO_2, water as solvent and polyethylene glycol (PEG) as additive. A coagulation bath was a solution of Na_2SO_4-KOH-H_2O. The resulting membranes possess good flexibility and mechanical strength. The pore diameter of the membranes is ...
