  • An Insight to Magnesium (Mg)
    Article - 29 Jul 2001
    Black was the first person to recognize magnesium (Mg) as an element in 1755. Later, in 1808, Davy isolated this element by evaporating mercury from a magnesium amalgam.
  • Lead - An Introduction
    Article - 28 Jul 2001
    Although lead occurs as such in nature, it is rare. Lead is chiefly obtained from galena (PbS) through the process of roasting.
  • Uranium
    Article - 23 Jul 2001
    Uranium is a heavy, silver-white metal resembling nickel. It is malleable, ductile, slightly paramagnetic and pyrophoric when finely divided. Its main uses are as a nuclear fuel, radioactive isotope...
  • Platinum - Properties and Applications
    Article - 23 Jul 2001
    Platinum (Pt) was discovered by Ulloa in 1735 and Wood in 1741. Platinum occurs as such naturally, together with negligible amounts of palladium, iridium, rhodium, osmium, and ruthenium.
  • A Background to Silicon and its Applications
    Article - 20 Jul 2001
    Silicon is synthesized commercially by heating carbon and silica in an electric furnace, using carbon electrodes.
  • Gold - Properties and Applications of Gold
    Article - 20 Jul 2001
    Gold is most widely known as a precious metal due to its high lustre and chemical inertness. It is also used for coinage, ornaments, jewellery, gilding, textile industry, radiation control,...
  • Cerium - Cerium (Ce) Properties and Applications
    Article - 20 Jul 2001
    Cerium is the most abundant of the rare earth metals. It is malleable and oxidises readily at room temperature. It is used in pyrophoric alloys for cigarette lighters and in the making of some...
  • An Insight to Beryllium
    Article - 20 Jul 2001
    Beryllium is a high melting point metal with low density. It is commonly alloyed with copper, aluminium and nickel. Other applications include aerospace, gyroscopes, radiation detectors and other...

The Current State of the Global Semiconductor Market

The global semiconductor market has entered an exciting period. Demand for chip technology is both driving the industry as well as hindering it, with current chip shortages predicted to last for some time. Current trends will likely shape the future of the industry, which is set to continue to show

How are Graphene Batteries Made?

How are Graphene Batteries Made?

The primary distinction between graphene-based batteries and solid-state batteries lies in the composition of either electrode. Although the cathode is commonly changed, carbon allotropes can also be employed in fabricating anodes.
