...carbon equivalent value. Group B. Heat-treatable alloys with mechanical properties affected by the welding process: e.g. plain carbon steel, alloy steel and precipitation-hardening Al-alloys. Group C. Materials which form brittle alloys or intermetallic compounds at the weld interface. This intermediate layer can usually be controlled to a few micrometers: e.g.:...

...carbon and oxygen. [deep sky image of the constellation Orion] The constellation Orion A good example of stars at different stages of their lives may be seen in the constellation of Orion, the hunter. Comprising seven bright stars, Orion is a familiar shape in the night sky – two stars mark his shoulders, and two stars mark his knees, with a belt of three stars across...

...carbon fibre reinforced plastic (CFRP) or glass fibre reinforced plastic. Sandwiches of CFRP are also used in many modern aircraft. Many of these materials are simply called laminates as they are indeed laminated together as each layer in built up and then cured with heat to precisely secure it into place.

...footprint. While not all bioplastics are biodegradable, they represent a more sustainable choice compared to traditional plastics, particularly in their use of renewable materials (Abe et al., 2021). The key to bioplastics’ potential lies in their ability to replace traditional plastics across a range of applications without compromising functionality. Whether it’s a...

...carbon fibre composite materials. It is powered by a Rolls-Royce Spey 205 jet engine, which is a development of the Spey 202 engine, and the project will research how to use sustainable waste-based fuel. The boat uses novel technologies, including super-cavitating hydrofoils (described in our online boat interactive linked below) and active stability and control systems....

...carbon dioxide. [Part of Nirgal Vallis, a valley on Mars first seen on this image by Mariner 9 in 1972. This image is 120km from side to side] Part of Nirgal Vallis, a valley on Mars first seen on this image by Mariner 9 in 1972. This image is 120km from side to side. In the 1970s attention turned to the much juicier topic of liquid water on Mars, with the discovery by...
