The resurgence of the lithium metal battery requires innovations in technology, including use non-conventional liquid electrolytes. inherent electrochemical potential (-3.04 V vs. SHE) inevitably limits its many solvents, such as acetonitrile, which could provide electrolytes with increased conductivity. aim this work is to produce an artificial passivation layer at metal/electrolyte interface that electrochemically stable acetonitrile-based To a interface, was immersed fluoroethylene...
We demonstrate an electrochromic device with self-bleaching ability that uses ethyl viologen- ([EV]2+) and ferrocene-based redox ionic liquids ([FcNTf]-) as the electroactive species. These compounds are insensitive to atmospheric O2 H2O in both their oxidized reduced states once dissolved a typical liquid electrolyte ([BMIm][NTf2]), allowing for be assembled outside glovebox without any encapsulation. This could generate deep blue color by application of 2.0 V potential between two...
The participation of biological agents in pulp bleaching systems has received a lot attention from research teams around the world, driven by environmental benefits that biobleaching could bring. Nature showed us ability some its agents, such as wood-decaying fungi, to delignify and bleach wood pulp. What we need do is enhance efficiency make them cope with fast pace our modern mills. To so, profound understanding system required. Our efforts discover new efficient mediators for...
Gel polymer electrolytes (GPEs) based on polyacrylonitrile elastomer (HNBR) are investigated for lithium-ion batteries application. This study examines the acrylonitrile content, as well solvent used to make GPE, understand their impact lithium solvation. To do so, we propose a three-component system comprising HNBR:solvent:LiTFSI pinpoint correct ratio provide GPE with competitive conductivity. Infrared spectroscopy is shed light interactions between nitriles and ions. Spin–lattice...
Several new protic ionic liquids (PILs) were prepared by mixing trifluoroacetic acid (TFA) with various heterocyclic amines using different base:acid ratios (1:1 and 1:2). Their specific conductivities have been measured electrochemical impedance spectroscopy found ranging from 0.71 to 9.07 mS·cm−1 at 27.0 °C. In all cases, the conductivity of a given liquid increased higher proportion (1:2 ratio) which is explained mainly smaller viscosity obtained in these conditions. Indeed, most PILs,...
Electrolytic solutions of lithium-ion batteries can be modified with additives to improve their stability and safety. Electroactive molecules used as such act an electron (redox) shuttle between the two electrodes prevent overcharging. The electroactive ionic liquid, 1-ferrocenylmethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide (TFSI), was synthesised its electrochemical properties were investigated when diluted ethylene carbonate–diethyl carbonate solvent at various...
Electrolyte-gated (EG) transistors, based on electrolyte gating media, are powerful device structures to modulate the charge carrier density of materials by orders magnitude, at relatively low operating voltages (sub-2 V). Tungsten trioxide (WO3) is a metal oxide semiconductor well investigated for applications in electrochromism, sensing, photocatalysis, and photoelectrochemistry. In this work, we report EG transistors making use mesoporous nanostructured WO3 thin films easily permeated as...
In this paper, we will describe in detail the setting up of a Design Experiments (DoE) applied to formulation electrodes for Li-ion batteries. We show that, with software guidance, Designs are simple yet extremely useful statistical tools set and embrace. An Optimal Combined was used identify influential factors pinpoint optimal formulation, according projected use. Our methodology follows an eight-step workflow adapted from literature. Once study objectives clearly identified, it is...
We describe methodologies for the generation and screening of combinatorial libraries electrocatalyst materials fuel cell applications, generated by cosputtering three elements onto a Si substrate coated with Ta adhesion underlayer. Screening was carried out via fluorescence assay as well scanning electrochemical microscopy. Whereas former provided rapid qualitative limited spatial resolution, latter high resolution. The method tested on Pt, PtBi, PtPb, PtRu nanoparticles, while both methods...
Poly(ethyleneimine) (PEI) microcapsules containing laccase from Trametes hirsuta (ThL) and versicolor (TvL) were printed onto paper substrate by three different methods: screen printing, rod coating, flexo printing. Microcapsules fabricated via interfacial polycondensation of PEI with the cross-linker sebacoyl chloride, incorporated into an ink, or coated on substrate. The same ink components used for printing methods, it was found that compatible ink. Enzymatic activity microencapsulated...
Today, energy conversion devices typically rely on composite electrodes made of several materials interacting with one another. Understanding their individual and combined impacts performance is essential in the pursuit optimized systems. Unfortunately, this investigation often disregarded favor quick publishable results. Here, designs experiments are shown as capable meeting both ends. Less than 100 different electrode formulations defined two active (LiFePO4 Li4Ti5O12), carbonaceous...
