Abstract:

The electrochemical reduction of iron (III) ions into zero-valent iron from a solution of ethylene glycol was accomplished. The kinetics and mechanism of the electroreduction process were investigated by cyclic and linear polarization techniques. The influence of temperature, potential sweep rate, and concentration of iron (III) ions on the electroreduction process was also studied. The observed values of effective activation energy revealed that the investigated electroreduction process is accompanied by mixed kinetics control. Moreover, the results of SEM and X-ray diffraction analysis confi

Abstract:

The electroreduction of Zn2+ was studied in propylene carbonate (PC), acetonitrile (ACN), and hexamethylphosphoramide (HMPA) on mercury at various concentrations of tetraethylammonium perchlorate as a supporting electrolyte using dc polarography, cyclic voltammetry, chronoamperometry, and ac polarography. It was found that in PC and ACN the electroreduction process proceeds in one step. In HMPA, however, the electroreduction proceeds through a CEE mechanism in which a chemical reaction is followed by a charge transfer in two steps.

Abstract:

The pathological aggregation of the microtubule-associated protein tau is a hallmark of various neurodegenerative disorders, including Alzheimer’s disease (AD), Pick’s disease and frontotemporal dementia. Tau protein’s reversible assembly and binding to microtubules in brain neurons are regulated by charge-neutralizing phosphorylation. Hyperphosphorylation, on the other hand, leads to irreversible formation of cytotoxic filaments. Under physiological conditions, tau remains remarkably stable, exhibiting intrinsically disordered behavior and reversible assembly. Irreversible aggregation require

Abstract:

According to numerous studies the electroreduction of Ti(IV) fluoride complexes to the metal in chloride-fluoride melts occurs in two subsequent stages: Ti(IV) + e- ↔ Ti(III) (1) Ti(III) + 3e- → Ti. (2) The redox reaction (1) in chloride-fluoride melts of different composition was thoroughly investigated in our previous works [1,2]. The aim of the present investigation was the determination of reaction (2) kinetic parameters such as: coefficients of transfer, diffusion coefficients of Ti(III) and standard rate constants of charge transfer, in the (NaCl-KCl)equimol.-NaF(10 wt.%)-K2TiF6 melt.

Abstract:

Electrocatalytic reduction of CO2 to fuels and chemicals is one of the most attractive routes for CO2 utilization. However, low efficiency and poor stability restrict the practical application of most conventional electrocatalysts. Here, a silver hollow fiber electrode is presented as a novel self-supported gas diffusion electrode for efficient and stable CO2 electroreduction to CO. A CO faradaic efficiency of over 92% at current densities of above 150 mA∙cm−2 is achieved in 0.5 M KHCO3 for over 100 h, which is comparable to the most outstanding Ag-based electrocatalysts. The electrochemical r

Abstract:

The increase of renewables on the electricity grid and diversification of chemical feedstocks offers opportunities for electrochemical reactions to be performed. Biomass-derived feedstocks can be upgraded electrochemically at the biorefinery before use or transportation for further valorization. Furanics are commonly found biomass-derived chemicals as a result of biomass upgrading from pyrolysis and other conversion methods and are considered key platform chemicals. Additionally, furfural is produced commercially, making it an existing feedstock stream that can be upgraded directly. 5-Hydroxym

Abstract Cu-Sn-Bi layer coated on Ti substrate was prepared using electrodeposition method and applied as cathode material for electrochemical reduction of nitrate in this research. Linear sweep voltammetry (LSV), chronoamperometry (CA), scanning electron microscope (SEM), energy dispersive spectrometry (EDS), X-ray diffraction (XRD) were used to scrutinize the electrochemical performance and the cathode materials. LSV results illustrated that Cu-Sn-Bi cathode possessed the ability for nitrate reduction. Preparation conditions including deposition time, current density, temperature and the con

Abstract:

The catalytic conversion of CO2 into higher-value industrial chemicals represents a key strategy for mitigating greenhouse gas emissions. However, conventional CO2 conversion processes are severely limited by catalytic activity and thermodynamic equilibrium at low temperatures, leading to low energy efficiency and restricted applicability. Electrochemical CO2 conversion emerges as a promising avenue for both reducing carbon emissions and generating valuable chemicals simultaneously. Proton ceramic electrochemical cells (PCECs) provide a unique platform for CO2 electroreduction and hydrogenatio
