Effect of temperature on kinetics of the hydrogen evolution reaction on Ni-P-C cathodes in alkaline solution
The kinetics of hydrogen evolution reaction (HER) was studied in 1M NaOH at various temperatures (298 to 358 K) on Ni-P-C (composite electrodes. The electrochemical efficiency of the electrodes has been evaluated on the basis of electrochemical data obtained from the steady-state polarization Tafel curves, electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) in 1M NaOH solut...
متن کاملIn situ activation of a Ni catalyst with Mo ion for hydrogen evolution reaction in alkaline solution
In this study Ni catalyst have been activated during hydrogen evolution reaction (HER) by adding Mo ions into the alkaline electrolyte. After dissolving different amounts of ammonium molybdate in the 1M NaOH as electrolyte, Ni catalyst was used as cathode for HER. Afterwards a comparison between hydrogen overpotential measured in Ni catalyst with and without in situ activation has been made; th...

متن کاملIn vitro reaction of barbiturates with formaldehyde.
Barbiturates are widely used as sedatives, hypnotics, and antiepileptics, and, when coupled with their narrow therapeutic index, the probability that their use will result in accidental or intentional death is significant. When barbiturates are implicated in a murder or suicide, analysis for their presence is often required. Under certain conditions, barbiturates are quite stable, but condition...
متن کاملFormaldehyde as a probe of DNA structure. r. Mechanism of the initial reaction of Formaldehyde with DNA.
Formaldehyde is used as a probe of the dynamic behavior of native DNA. We first show experimentally how initial denaturation rates vary with temperature, formaldehyde concentration, DNA melting temperature, and DNA molecular weight. Electron microscopy of DNA from the initial phases of the reaction verifies that denaturation initiates a t AT-rich regions in the interior of the DNA molecule. The...
