In this paper, we performed solid-state nuclear magnetic resonance (NMR) measurements, including T1H and T1ρ, of silk fibroin (SF)/polyurethane (PU) composites to examine their possible use as a material for artificial vascular grafts. In the develo

Benzyldimethyltetradecylammonium (BA14(+)) salts with anionic ligands (X(-)), such as bis(2-ethylhexyl)sulfosuccinate, bis(2-ethylhexyl)phosphate (BEHP(-)), and benzotriazole (BTA(-)) anions, were prepared. These salts were soluble in various organic

Benzyldimethyltetradecylammonium (BA14+) salt with bis(2-ethylhexyl) sulfonatosuccinate (BEHS−) anion maintains its liquid state even at room temperature, so it can be regarded as a halogen-free lo...

It has been shown that polyammonium cations comprising quaternary ammonium and hydrophilic groups such as amide and hydroxyl groups stabilize a redox enzyme bilirubin oxidase (BOD). The BOD catalyzes the reaction: 4[Fe(CN)6]4- + 4H+ + O2 --4[Fe(CN)6]

Cyclic voltammograms of the aqueous solution containing polyammonium cations and the [Fe(CN)6]4-. anion at a plastic-formed carbon or platinum electrode were recorded. Polyammonium salts comprising quaternary ammonium in the main chain or sub chain a

At about 50 wt% Ni content, Ni-plated polytetrafluoroethylene (Ni-PTFE) particles show conductivity of 300 S m−1 when plated on 25 μm PTFE particles. For this study, Ni-PTFE particles were formed into the Ni-PTFE plate using heat treatment at 350

A Ni electroless plating process was used with polytetrafluoroethylene (PTFE) fine particles (25–500 μm). Using nonionic hydrocarbon surfactant, PTFE particles were dispersed in the plating bath. The PTFE hydrophobicity was sufficiently high that

The microstructure of poly(vinyl alcohol- co -vinyl levulinate) (VOH–VLA copolymer) was studied by 1 H NMR and 13 C NMR techniques. The sequence distributions could be obtained from the six methine triads observed in the 500-MHz 1 H NMR spectra of
