In Situ Constructing Ultrathin, Robust-Flexible Polymeric Electrolytes with Rapid Interfacial Ion Transport in Lithium Metal Batteries.

Safety of lithium metal batteries (LMBs) has been improved by using the solid-state polymer electrolytes, but the performance of LMBs is still troubled by the poor interface of solid electrolytes/electrodes, leading to insufficient interfacial Li transport. Here, a novel ultrathin, robust-flexible polymeric electrolyte is achieved by in situ polymerization of 1,3-dioxolane in soft nanofibrous skeleton at room temperature without any extra initiator or plasticizer, leading to the electrolyte with rapid interfacial ion transport. This facilitated Li transportation is demonstrated by molecular dynamics simulation.

EHDA Spraying: A Multi-Material Nano-Engineering Route.

Electrohydrodynamic atomization (EHDA) enabling platform technologies have gathered significant momentum over the last two decades. Utilisation of the underpinning jetting process in tandem with desired materials (including polymers, ceramics, metals and even naturally occurring compounds such as peptides, DNA and cells) provides the basis for novel engineered therapies. Through EHDA processes, the generation of a variety of nano-meter and micro-meter scaled structures with control on surface and encapsulation features is attainable in a single step.

Safety evaluation on low-molecular-weight hydroxyethyl starch for volume expansion therapy in pediatric patients: a meta-analysis of randomized controlled trials.

Introduction: Hydroxyethyl starch (HES) has been widely used for volume expansion, but its safety in adult patients has been questioned recently. The aim of this meta-analysis is to see whether or not HES has any adverse effect in pediatric patients.

Methods: Randomized controlled trials (RCTs) involving pediatric patients who received 6% low-molecular-weight HES, published before January 2014, were searched for in Pubmed, Embase database and Cochrane Library.

Strategies to decrease bile duct injuries during laparoscopic cholecystectomy.

Background: Laparoscopic cholecystectomy (LC) has been performed clinically for more than 20 years. However, the incidence of bile duct injury (BDI) remains high despite attempts to prevent and reduce it. The aim of this study was to use an intraoperative unfavorable factors ratings system to identify unfavorable intraoperative factors and evaluate the effectiveness of application of the system in reducing BDI during LC.
