The electrochemical properties of a composite solid polymer electrolyte, consisting of poly(ethylene oxide) (PEO)-lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) and tetraethylene glycol dimethyl ether (TEGDME) was examined as a protective layer between lithium metal and a water-stable lithium ion-conducting glass ceramic of Li1+x+y(Ti,Ge)2-xAlxP3-ySiyO12 (LTAP). The lithium ion conductivit...

We present a method for characterizing the adsorption of solutes in microfluidic devices that is sensitive to both long-lived and transient adsorption and can be applied to a variety of realistic device materials, designs, fabrication methods, and operational parameters. We have characterized the adsorption of two highly adsorbing molecules (FITC-labeled bovine serum albumin (BSA) and rhodamine...

The straightforward molecular modelling of an aqueous surfactant system at concentrations below the critical micelle concentration (pre-cmc) conditions is unviable in terms of the presently available computational power. Considering a typical nonionic surfactant, a fully atomistic simulation that includes several micelles will require in excess of O(10) atom sites and several nanoseconds of rea...

An all-organic symmetric redox-flow battery (RFB) that employs nitronyl nitroxide (NN) units as a bipolar redox-active chargestorage material was designed and investigated. An organic molecule possessing two bipolar redox-active NN units connected via a tetraethylene glycol chain was synthesized for this purpose. Owing to the ethylene glycol chain, this molecule demonstrates good solubility in ...

The human population is widely exposed to polyethylene glycol (PEG) and its chemical derivatives, which are widely used as vehicles or co-solvents in many pharmaceutical and cosmetic preparations. However, PEG polymers of low molecular weight differ significantly from polymers of higher molecular weight in their physico-chemical properties, biological effects on cell permeability and their abso...

Vanadium oxides are highly valued as electrochromic materials because of their multicolor capabilities. However, practical applications have been limited due to challenges such the dissolution vanadate into aqueous electrolytes, leading poor long-term stability. Herein, a solution is proposed issue by utilizing hybrid electrolyte consisting tetraethylene glycol dimethyl ether (TEGDME) and water...

Lithium–O2 batteries represent one of the most appealing candidates for battery electric vehicles because their remarkable theoretical high energy density, similar to fossil fuels. Solid polymer electrolytes a plausible solution tackle some challenges associated with conventional liquid-based Li–O2 batteries, including safety concerns. Herein, cross-linked robust gel (GPEs) based on poly(ethyle...
