  • Hafnium (Hf) - Properties and Applications
    Article - 19 Dec 2001
    Hafnium has a bright silver luster and is naturally ductile. The metal has a tightly-packed hexagonal crystal structure. It also has excellent resistance to corrosion.
  • An Overview of Gallium
    Article - 18 Dec 2001
    Gallium is present as a trace element in germanite, sphalerite, diaspore, coal, and bauxite. Although this metal occurs naturally in approximately the same amount as lead, it is extensively dissipated...
  • An Overview of Gadolinium
    Article - 18 Dec 2001
    Marignac first isolated gadolinia, an oxide of gadolinium (Gd), in 1880. Then, in 1886, Lecoq de Boisbaudran successfully separated the element from Mosander’s “yttria.”
  • Francium (Fr) - Properties and Applications of Francium
    Article - 18 Dec 2001
    Francium is an alkali metal that occurs naturally as a radioactive decay product of actinium. While 29 isotopes have been identified, knowledge and properties are scarce, owing to its instability.
  • Fermium
    Article - 18 Dec 2001
    Fermium is an actinide element whose properties have been extremely difficult to measure due to short half lives of the isotopes. It has no known commercial value.
  • Europium - Properties and Applications
    Article - 18 Dec 2001
    Europium (Eu) is part of the lanthanide series of elements. Demarcay discovered this element in 1901, and succeeded in isolating it in a fairly pure form from the earth.
  • An Introduction to Erbium
    Article - 18 Dec 2001
    Part of the lanthanide series, erbium (Er) is a rare-earth element found in a wide range of minerals like blomstrandine, polycrase, fergusonite, euxenite, xenotime, and gadolinite.
  • Einsteinium
    Article - 18 Dec 2001
    Einsteinium is a member of the actinide series of elements. While several isotopes have been identified, it has no known commercial value.
  • An Introduction to Dysprosium
    Article - 18 Dec 2001
    Dysprosium (Dy) is a chemical element belonging to the actinide series. In 1950, Spedding and colleagues isolated the element using techniques like metallographic reduction and ion-exchange...
  • Curium
    Article - 18 Dec 2001
    Curium is a radioactive actinide element. It is toxic to humans and has few commercial applications but has been proposed as an isotope power source.

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.
