Redox properties of H(2)TFcP [TFcP(2-) = 5,10,15,20-tetraferrocenylporphyrin(2-)] were investigated using cyclic voltammetry, differential pulse and square-wave voltammetry methods in a large variety solvents electrolytes. When DMF, THF, MeCN used with TBAP as the supporting electrolyte, first oxidation wave was assigned to single four-electron process reflecting simultaneous all iron(II) centers into iron(III) H(2)TFcP. an o-DCB (1,2-dichlorobenzene)/TBAP combination electrochemical...
Nanoporous NiO thin film electrodes were obtained via plasma-assisted microwave sintering and characterized by means of a combination electrochemical techniques X-ray photoelectron spectroscopy (XPS). The aim this study is the elucidation nature surface changes introduced redox processes nanostructured material. undergoes two distinct oxidation in aqueous electrolyte with progress anodic polarization. These findings are consistent sequential formation oxyhydroxide species at surface,...
The application of deep eutectic solvents (DESs) to dissolve metal oxides in lithium-ion batteries (LIBs) recycling represents a green technological alternative the mineral acids employed hydrometallurgical processes. However, DESs are much more expensive than and must be reused ensure economic feasibility LIB recycling. To evaluate DES reusability, role choline chloride-ethylene glycol decomposition products on dissolution was investigated. temperatures generally applied carry this leaching...
Lithium recovery from end-of-life Li-ion batteries (LIBs) through pyro- and hydrometallurgical recycling processes involves several refining stages, with high consumption of reagents energy. A competitive technological alternative is the electrochemical oxidation cathode materials, whereby lithium can be deintercalated transferred to an electrolyte solution without aid chemical extracting compounds. This article investigates potential selectively recover Li LIB materials by direct extraction...
The pressing need for multifunctional materials in medical settings encompasses a wide array of scenarios, necessitating specific tissue functionalities. A critical challenge is the occurrence biofouling, particularly by contamination surgical environments, common cause scaffolds impairment. Beyond imperative to avoid infections, it also essential integrate with living cells allow regeneration, mediated cell attachment. Here, we focus on development versatile material applications, driven...
The molecular layer that adsorbs on the biomaterial surface upon contacting body tissues and fluids, termed conditioning (CL), influences cell behavior regulating scaffold integration resilience in a patient-specific fashion.
A novel ecofriendly electrochemical sensor for in-situ detection of testosterone based on gold nanoparticles (AuNPs) and a semi-amorphous metal organic framework (MOF) has been developed clinical diagnosis doping control.
