Biodegradable smart materials with self-healing and shape memory function for wound healing.

Notwithstanding the rapid development of suture elastomers to meet the needs of practical surgery, utilizing the elastomers' self-healing function as a surgical suture to facilitate the healing of wounds has not been addressed. Here, a biodegradable aliphatic polycarbonate smart elastomer, mPEG--PMBC , was synthesized from aliphatic polycarbonate monomer with methoxy polyethylene glycol (mPEG, 5.0 kDa) as initiator, which exhibited excellent mechanical properties, highly efficient self-repairing, and remarkable shape memory behavior.

Highly effective removal of Hg(ii) solution using corn bract@MoS as a new biomass adsorbent.

As known, mercury contamination is one of the current environmental issues due to the high toxicity of mercury. Corn bract (CB) is an agricultural by-product, and its final treatment is generally incineration that causes air pollution. In this study, a new type of high-efficiency biomass adsorbent (CB@MoS) for adsorption of Hg(ii) was obtained, and its morphology and structure were characterized with FT-IR, XRD, SEM and TEM.
