Hindered urea bonds are introduced as self-healing units in a polymer electrolyte for Li-metal batteries. Differently from standard commercial separators, the poly(urea-urethane) system works hundreds of cycles after several damage/healing steps.

We synthesized the novel methacrylate monomer bearing an oxazolidone structure (M1) and performed radical polymerization of M1 by traditional procedures. The glass transition temperature (Tg) obtained polymer (P1) was a significantly high value compared to that poly(methyl methacrylate) typical poly(urethane methacrylate)s. copolymers monofunctional urethane derived from 2-hydroxyethyl phenyl i...

H ADDOW and Sexton’ noted a coincidental depression of the leukocyte count during the course of observations on the effect of various forms of urethane On the growth of experimentally produced tumors in the rat. As a result, the various forms of urethane, principally ethyl carbamate, were subsequently utilized in the treatment of leukemias and other types of malignant disease by Paterson, Thoma...

corrosion makes huge economic and ecologic damage all over the world. biologic corrosion of sewer pipes is considered as a serious limitation in economic perspectives. to prevent biologic corrosive damage, lining techniques can be applied by materials and aggregate resistant to attack bacterially in sewer pipes. the role of bacteria is that they convert sulfur compounds into sulfuric acid which...

conclusions despite the fact that anesthesia in chronic liver disease is a scary and pretty challenging condition for every anesthesiologist, this hazard could be diminished by meticulous attention on optimizing the patient’s condition preoperatively and choosing appropriate anesthetic regimen and drugs in this setting. although there are paucity of statistics and investigations in this specifi...

We have used a series of in vitro and in vivo tests to assess the suitability of two new degradable polymers for application as coatings for drug-eluting stents. The first is a family of urethane-linked multi-block copolymers (MBCP) that comprise blocks of lactide, glycolide, epsilon-caprolactone and/or poly(ethylene glycol) chain-extended with 1,4-butanediisocyanate (SynBiosys polymers). The s...

A vanillin derivative containing ?-hydroxy-amine functionalities was introduced into vitrimer materials using vinylogous urethane chemistry. These new have a high bio-based content and show fast reprocessability.

The transcription factor CCAAT/enhancer-binding protein α (C/EBPα) is a basic leucine zipper transcription factor and is expressed in alveolar type II cells, alveolar macrophages and Clara cells in the lung. Although decrease or absence of C/EBPα expression in human non-small cell lung cancer suggests a possible role of C/EBPα as a lung tumor suppressor, there is no direct proof for this hypoth...
