Sapphire is a high-purity and high-density, single-crystalline form of aluminum oxide that may contain chromia, titania, yttria, or other dopants. Sapphire is usually transparent or translucent.

In the lab Researchers at TU Wien employed noncontact atomic force microscopy and computational modelling to determine the structure of the aluminium oxide surface. (Courtesy: TU Wien) Determining the ...

As haulage companies and drivers adapt to the electrification era, understanding the key terminology is crucial. Here’s a ...

It didn't matter if it was a coupé or a pickup truck, that strong metal was always the way to go. That was until the 1970s ...

[Rini Anita] is exactly that rare breed, creating this aluminum RC truck from scratch. The truck itself is a cab-over — short for Cab Over Engine (COE), a style seen making local deliveries ...

Joe walks us through how he restores a rusty 1960s Structo airport truck, from removing the rust to powder-coating the parts.

Raw aluminium readily forms a tough oxide layer when exposed to air, which protects the metal from further corrosion or reactions with many chemicals. This oxide layer can form incredibly quickly ...

happens when a metal continues to oxidise. The metal becomes weaker over time, and eventually all of it may become metal oxide.

Researchers led by Saudi Arabia’s King Khalid University have developed a 3D-printed anti-reflective coversheet for PV modules. The cover sheet is based on cyclic-olefin copolymers (COC), to ...

A compact truck is a vehicle with a pickup bed that retains the general shape, utility, and attitude of a pickup truck, except in a smaller size. Are small trucks safe? Like any passenger vehicle ...
