It is shown that the kinetics of vacancy coagulation to macroscopic erosion voids indilute crystalline metallic alloys depends strongly on the chemical nature of the soluteelement. In numerous published and the author's own electromigration data, it was foundthat the formation of erosion voids is ...
Copper is an essential element although excess copper is toxic.General Information Copper is a good conductor of heat and electricity - hence its use in the electrical industry.It is resistant to air and water but slowly weathers to the green patina of the carbonate often seen on roofs and ...
Copper (Cu) is a transition element, belonging to Group 11 (formerly Group IA) of the Periodic Table. It is an important non-ferrous metal and a micronutrient with two distinct functions - to serve as a plant nutrient by being an activator or by being a part of certain enzymes like tyro...
Enhancement factors are determined by the electrostatic potential of the thiophene molecular surface and the electronic configuration of the doping metal. The more negative the electrostatic potential, the stronger is the interaction. The influence of the d-block transition metal element (Sc) is larger...

(EDX) mapping and spectroscopy results proved the Cu element is evenly distributed on the GDE (Supplementary Figs.14,16and Supplementary Table4). STEM/EDX and TEM images taken pre- and post-electrolysis also support the claim that Cu nanoclusters (~2–5 nm) were formed during the reaction...
Single-atom catalysts (SACs) with adjustable and isolated active sites have been applied to electrochemical catalysis32,33,34, showing potential in expelling C-C coupling in CO2RR. Particularly, the unique 3dtransition-metal-four nitrogen (M-N4) configuration consisting of an isolated single metal ...
