Silicon (Si) is a metalloid, element number 14 on the periodic table. Like carbon, silicon has four bonding sites, but silicon is more than twice as heavy as carbon. The high melting point of ...

Silicon is, after oxygen, the most abundant element of the Earth's crust. But although about 75% of the Earth is made from silica — or silicon dioxide (SiO 2), the main constituent of silicate ...

IT is unusual to write a whole volume about a single oxide of one of the elements; but if any oxide deserves this place of honour, it is certainly silica, since no other compound possesses such an ...

Researchers in India have demonstrated a wet chemical process to recover silicon with high purity from end-of-life solar panels, which they used to make functionalized silica nanoparticles.

One of the themes I remember from these stories was the idea that alien life forms, often based around the element silicon, abounded elsewhere in the universe. Why silicon? Well, it is often said that ...

Oxides contain at least one oxygen atom, and silicon oxide may refer to silicon dioxide (SiO 2) or silicon monoxide (SiO). Silicon dioxide is a hard, glassy mineral found in materials such as rock ...

Scientists in the US built the first silicon transistor in 1947. Before that, the mechanics of computing had been performed by vacuum tubes, which were slow and bulky. Silicon changed everything.
