Abiogenesis

In evolutionary biology, abiogenesis, or informally the origin of life (OoL), [3] [4] [5] [a] is the natural process by which life has arisen from non-living matter, such as simple organic compounds.[6] [4] [7] [8] While the details of this process are still unknown, the prevailing scientific hypothesis is that the transition from non-living to living entities was not a single event, but an

Crystals

Two-dimensional (2D) electron back scattered diffraction (EBSD) is a powerful tool for microstructural characterization of crystalline materials. EBSD enables visualization and quantification of the effect of synthesis methods on the microstructure of individual grains, thus correlating the microstructure to mechanical and electrical efficiency. Therefore, this work was designed to investigate

MMO Anodes (Mixed Metal Oxide) for Cathodic

The catalytic life is significantly reduced when the primary reaction is the evolution of oxygen (fresh water, soil, coke backfill and concrete environments). Iridium Oxide (IrO 2 ) Most CP manufacturers use Iridium Oxide based mixed metal oxide for their cathodic protection anodes because it is suitable for both chlorinating and oxygenating environments.

Benchmarking of oxygen evolution catalysts on porous

The oxygen evolution reaction (OER) is the main anode reaction for electrochemical CO2 reduction and solar fuel production. We report a benchmarking study of some of the most active OER catalysts deposited on nickel foam and characterized by using a standardized protocol. The importance of the porosity of the support was highlighted as an important feature and led us to design a new dendritic

Frontiers

CO 2 can be valorized with three main routes. The "No transformation" route will not be described in this review as it is out of the scope of this article. With a "Chemical CO 2 conversion" route, it is technically possible to use CO 2 as a carbon source for the synthesis of commodity products, from simple CO to liquid fuels and high-molecular-weight polymers (Hu et al., 2013).

The oxygen electrocatalysis, i.e. the oxygen reduction and evolution reactions, is traditionally executed using noble metal and metal oxide-based nanostructures. However, they are associated with many disadvantages such as high cost, lower durability/selectivity and detrimental environmental effects; this motivates researchers to develop new electroactive materials.

Quantitative analysis by in situ measurement of oxygen gas evolved from an anode was employed to monitor the progress of electrolytic reduction of simulated oxide fuel in a molten Li 2 O–LiCl salt. The electrolytic reduction of 0.6 kg of simulated oxide fuel was performed in 5 kg of 1.5 wt.% Li 2 O–LiCl molten salt at 650C.

Anodic Materials for Electrocatalytic Ozone Generation

Tin dioxide as anode, due to its high oxygen evolution potential, may inhibit the thermal dynamic favorable reaction for oxygen evolution.

Solid oxide fuel cell

Introduction Solid oxide fuel cells are a class of fuel cells characterized by the use of a solid oxide material as the electrolyte.SOFCs use a solid oxide electrolyte to conduct negative oxygen ions from the cathode to the anode. The electrochemical oxidation of the hydrogen, carbon monoxide or other organic intermediates by oxygen ions thus occurs on the anode side.
