determination of trace elements in food is of great importance, as some of them have nutritional significance, whilst others are toxic. long-term exposure to low levels of toxic metals could be important, especially in relation to children. differential pulse anodic stripping voltammetry (dpasv) is applied to simultaneous determination of lead, cadmium, copper and zinc in dry ash infant formula...

Electrochemistry along with advanced surface analyzes (X-ray photoelectron spectroscopy and time-of-flight secondary ion mass spectrometry) were implemented to investigate copper corrosion inhibition by 2-mercaptobenzothiazole (2-MBT) in hydrochloric aqueous solution the effects of electrochemical control on formation inhibiting interface. It is shown that reducing native oxide cathodic reducti...

The anodising process parameters (voltage, temperature, and electrolyte) control the morphology chemical composition of resulting anodic oxide film by altering balance between growth dissolution reactions. porosity is reduced addition tartaric acid to a sulfuric electrolyte, while at elevated temperatures enhances dissolution, leading wider pores rougher surfaces. No significant changes in as f...

Lithium–sulfur batteries (LSBs) are called to complement current state-of-the-art lithium-ion devices. However, despite the optimization of cathode and electrolyte, usage metallic lithium as anodic material is linked several problems that give place constant degradation anode. These processes become main bottleneck for LSBs their real application; therefore, solving these challenges related met...

Four types of titanium (Ti)-based electrodes were tested in the same microbial fuel cell (MFC) anodic compartment. Their electrochemical performances and the dominant microbial communities of the electrode biofilms were compared. The electrodes were identical in shape, macroscopic surface area, and core material but differed in either surface coating (Pt- or Ta-coated metal composites) or surfa...
