How to Determine Which Element Is in an Oxidation Reaction
An easy mnemonic to help you remember redox is OIL RIG, or "Oxidation is loss, Reduction is gain." A species that is oxidized in a reaction loses electrons, which means it has a higher, or more positive, oxidation number; a species that is reduced gains electrons, meaning it has a lower, or more neg
Styles of Extruded Aluminum Rails
Extruded aluminum rail is used to build rip fences, and create window frames and car parts. Extruded aluminum rails can be hollow or solid. Extruded aluminum rails are used due to their light weight and low cost. Extruded aluminum's mechanical properties are defined by the American Society for Testi
DIY Optical Encoder
An optical encoder is a sensor used to measure the rotation of a shaft via a computer or microcontroller.
