Biodegradable cross-linked poly(L-lactide-co-ε-caprolactone) networks for ureteral stent formed by gamma irradiation under vacuum

Sulfonated phenylamine ionic liquids as efficient phase-separation catalysts for the synthesis of trimethylolpropane triacrylate

“…Trimethylolpropane triacrylate (TMPTA) with three unsaturated double bonds is an important organic chemistry intermediate, which has been widely applied in plasticizers, cosmetics, electronics, textiles, printing, medicine and other related fields. [1][2][3][4][5][6][7][8][9] TMPTA is usually obtained by the direct esterification of acrylic acid and trimethylolpropane (TMP) or transesterification of methyl acrylate and TMP using acid catalysts, such as sulfuric acid, HF, methylsulfonic acid, phosphoric acid, etc. [10][11][12] Although these mineral liquid acids are efficient catalysts, homogeneous catalysis often caused difficult catalyst separation, equipment corrosion and environmental pollution.…”

A novel biodegradable ureteral stent with antibacterial ability to inhibit biofilm formation

“…As for ureteral stents, the material not only needs to have good biocompatibility, but also needs to be relatively flexible 4,15 . Now our group has made a lot of progress in the field of biodegradable ureteral stents [16][17][18] . PLACL is a relatively successful material for the next generation of ureteral stents that can synthesize into amorphous elastomer with good toughness and biodegradability.…”
