While alum contains aluminum as a component, the term "alum" encompasses a broader range of compounds and should not be confused with the elemental form, aluminium. The use and applications of alum and aluminium diverge significantly; alum is often found in specific industrial and cosmetic applicat...
I see they make some great looking touring bikes, but only in Aluminium.…I asked them why they dont do Steel and their reply was that the Steel / Belt Drive combination is not good, ie to flexible and that the belt will wear just as fast as a regular chain, therefore, they go with...
Aluminum nitride is often found in crystalline form, grown in a lab. The thin sheets of the chemical have piezoelectric properties, meaning it generates some electricity when placed under physical, mechanical stress. This makes the substance perfect in electronics and transducers....
When it comes to processing (dismantling and extraction of components), both sides engage in fierce competition over end-of-life (EOL) devices and the valuable fractions such as gold, silver, copper, and aluminium that are contained within them [16]. Many of China's main informal recycling ...
They started off with an aluminium frame, then binned it and decided to go with a carbon fibre tub. It was going to be a V8 hybrid, then a 5.0-litre V10, but emerged with a 4.8-litre V10, to pay homage to Toyota’s dire form in Formula One, which had already ditched V10 engin...
The ubiquitous use of chromium and its derivatives as corrosion preventative compounds accelerated rapidly after the second industrial revolution, with such compounds now integral to modern society. However, the detrimental impact of chromium compounds o
Why does polythene charge with rubbing but not copper? What makes copper good conductor but not polythene? Explain why copper wire is a good conductor of electricity. Why can't all materials become superconductors? Explain why argon does not form ionic bonds. ...
