Arginine (Arg) is a commonly used additive to prevent protein aggregation and inactivation in denaturing solutions. This paper presents new findings on the synergistic effect on the prevention of heat-induced aggregation of lysozyme using Arg in combination with polyethylene glycol (PEG). The synergistic enhancement was observed in the presence of Arg with amphiphilic polymers, such as PEG6000,...

Poly(vinyl alcohol) and polyethylene polymer systems were built in order to study their transport properties (diffusion). First a verification of the AMBER force field was conducted for a poly(vinyl alcohol) system built from a chain with 145 repeating units. NPT-molecular dynamics simulations at temperatures between 400 and 527 K were performed. The results of the simulations were compared wit...

In the current study, we report new flexible, free standing and high performance electrodes for electrochemical supercapacitors developed througha scalable but simple and efficient approach. Highly porous structures based on carbon fiber and poly (vinyl alcohol) (PVA) were used as a pattern. The electrochemical performances of Carbon fiber/GO-MnO2/CNT supercapacitors were characteriz...

Most gas barrier films produce cracks that lead to a significant loss of integrity when strain is applied. In order fabricate stretchable with low water permeability and high endurance after stretching, we used polydiallydimethylammonium (PDDA) mixed graphene oxide (GO) poly (vinyl alcohol) (PVA) montmorillonite (MMT). These were manufactured by layer-by-layer assembly on an Ecoflex/polydimethy...
