Danger Fallouts of Accidental Ingestion of Limescale Removers

Neutralisation capacity of limescale remover solutions is relatively low; it is comparable with vinegar (9% acetic acid) in 3 fold dilution with water. Furthermore NC slightly decreases in time, as part of remover is consumed by the reaction with lim...

Participation of electrochemistry in the studies of human metabolism

The contribution deals with explanation of metabolism of long term supplemented creatine in human organism. This process differs from metabolism of natural endogenous creatine, which is excreted in form of creatinine. Exogenous creatine induces incre...

Electrolytic processes in various degrees of dispersion

While following voltammetric behavior of ultrafine metallic powders, we realized that the results obtained with six metals (Al, Fe, Ni, Cu, Mo, and W) were providing us with material for treating the connection between electroactivity and the state o...
