Electrocatalysis (OER)

Background With the rapid increase in global energy demand, the burning of fossil fuels has caused a series of environmental problems. Researchers at home and abroad are committed to exploring clean energy and environmentally friendly and efficient energy storage and conversion devices. With the ...

Metal Corrosion

Metal Corrosion When the metal material is in contact with the surrounding medium, the material is destroyed due to chemical or electrochemical action. Metal corrosion is a thermodynamic spontaneous process, converting a metal of high-energy state into a metal compound of a low-energy state. Among ...

EIS measurements of 4 coating samples

EIS measurements of 4 coating samples Aim: to evaluate the protection of coating(through different treatments) on the low carbon steel based on EIS measurements Four types of samples: #1: coating sample through oiling plate vitrification #2: coating sample through oiling plate phosphating #3: ...

Polarization phenomenon in lithium batteries

Polarization is an important issue in chemical power sources, and opinions vary on the understanding of polarization in lithium batteries. Synthesizing documents and materials, we make the explanation as follows: Voltage plateau reduction during discharge of lithium batteries is mainly resulted from ...

Corrosion inhibitor assessment

For corrosion inhibitor assessment, usually people don’t calculate the corrosion rate, or MPY. Usually we get the inhibiting efficiency, that is a percentage. For example, with blank solution without adding inhibitor, we get a i0. If inhibitor 1 is added, we get i1. If inhibitor #2 is added we get ...

Corrosion resistance of implant materials

Corrosion resistance of implant materials Experiment purpose This experiment aims to measure the corrosion resistance abilities of two metal implants in simulated body fluid. The metal implants are mesh disk woven with wire after surface treatment - black and red. Preparation Reference electrode: ...
