چکیده

Hydrogen is the source of energy that unites the metabolisms and fuels the innovative potentials of all living organisms. Autotrophs use hydrogen emitted into hydrothermal vents, where symbiotic communities that share hydrogen thrive. On the surface, life developed using photons to cleave water, releasing hydrogen carried into a reverse Krebs cycle to produce carbohydrates, from which hydrogen and its constituent electron and proton are extracted. Fluctuant electrogenic power is harnessed by extensive exchanges and symbiotic sharing schemes of hydrogen sources and carriers. These communicate with electrostatic nuclear centres, forming a positive feedback loop. If the proton-motive circuitry fails from loss of Redox potential, premature ageing and all-category disease can result.

In 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...

Application of Pd-Substituted Ni-Al Layered Double Hydroxides for the Hydrogen Evolution Reaction

Clean production of hydrogen from electrochemical water splitting has been known as a green method of fuel production. In this work, electrocatalytic hydrogen evolution reaction (HER) was investigated at new prepared layered double hydroxides (LDH) in acidic solution. NiAl/carbon black (CB) LDH was monitored using x-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scannin...

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...

Marine Chemosynthetic Symbioses

Bacteria and marine eukaryotes often coexist in symbioses that significantly influence the ecology, physiology and evolution of both partners. De Bary (1879) defined symbiosis as “the living together of differently named organisms,” implying that the term encompasses both positive (e.g., mutualism) and negative (e.g., parasitism) associations. Many researchers now view symbiotic interactions as...
