This article explores a CO 2 utilization option by investigating sustainable and economic catalytic conversion of -based oxalic acid to glycolic monomer. Ideal catalyst design principles reaction conditions were established for this novel process.

Poly (lactic-co-glycolic acid) (PLGA) is a kind of medical polymer material with good biodegradability and histocompatibility, which widely used in postoperative anti-adhesion materials. In this paper, PLGA microfiber membrane was successfully prepared poly(lactic-co-glycolic as the main by electrospinning technology. The surface morphology, wettability, dimensional stability mechanical propert...

Hydrogen sulphide (H2S) is an endogenous gaseous signalling molecule observing cardioprotective qualities in various experimental models. However, its therapeutic application limited due to rapid release vivo and potential toxicity. Controlled-release nanoparticles (NPs), such as polylactic-co-glycolic acid (PLGA) NPs entrapping H2S compounds may address these issues. PLGA NPs’ encapsulating so...

Pure and aqueous methanol were used for radiation induced incorporation of CO at elevated pressure (up to 15 bar). The initial yields (G,) of the main products in pure methanol under 15 bar CO and 1 bar N 20 were found to be: G, (formaldehyde) = 3.80 and G;(glycolic aldehyde) = 2.0. For aqueous (10“ 2 mol • dm -3 ) methanol under 15 bar CO (dose: 0.557 kGy, pH — 2): the yields were G (formaldeh...

BACKGROUND Glycolic acid is a C2 hydroxy acid that is a widely used chemical compound. It can be polymerised to produce biodegradable polymers with excellent gas barrier properties. Currently, glycolic acid is produced in a chemical process using fossil resources and toxic chemicals. Biotechnological production of glycolic acid using renewable resources is a desirable alternative. RESULTS The...
