A mini review: Shape memory polymers for biomedical applications

Kaojin Wang, Satu Strandman, X. X. Zhu

Frontiers of Chemical Science and Engineering 2017, Volume 11, Issue 2,   Pages 143-153 doi: 10.1007/s11705-017-1632-4

Abstract: Shape memory polymers (SMPs) are smart materials that can change their shape in a pre-defined manner under a stimulus. The shape memory functionality has gained considerable interest for biomedical applications, which require materials that are biocompatible and sometimes biodegradable. There is a need for SMPs that are prepared from renewable sources to be used as substitutes for conventional SMPs. In this paper, advances in SMPs based on synthetic monomers and bio-compounds are discussed. Materials designed for biomedical applications are highlighted.

Bile duct injury repair — earlier is not better

Vinay K. Kapoor

Frontiers of Medicine 2015, Volume 9, Issue 4,   Pages 508-511 doi: 10.1007/s11684-015-0418-7

Abstract:

Bile duct injury is a common complication of cholecystectomy.The timing of bile duct injury repair remains controversial.Most patients with bile duct injury present with bile leak and sepsis; thus, early repair is not recommendedPercutaneous drainage of bile and endoscopic stenting are the mainstays of treatment of bile leak becausethey convert acute bile duct injury into a controlled external biliary fistula.

Optimization of pretreatment of Jatropha oil with high free fatty acids for biodiesel production

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 2,   Pages 210-215 doi: 10.1007/s11705-012-1282-5

Abstract: A central composite rotatable design and response surface methodology were used in order to investigate the individual and combined effects of the ethanol-to-oil ratio, H SO concentration, temperature and time of reaction on the reduction of free fatty acid (FFA) in jatropha oil. A quadratic polynomial model relating the reaction variables with FFA reduction was developed, presenting a good coefficient of determination ( = 0.893). For reducing FFA to less than 1%, the optimal combination was found to be 0.62 v·v ethanol-to-oil ratio (14.9 v·v ethanol-to-FFA ratio), 1.7% v·v H SO concentration, and 79 min reaction time at a reaction temperature of 54°C. These results are of great relevance to maximize methyl esters formation by transesterification using an alkaline catalyst.
