  • High Thermal Conductivity Graphite Foam for Protective Clothing
    Article - 26 Jun 2002
    Researchers have developed a high thermal conductivity graphite foam designed for use in protective clothing such as flight suits and race car overalls. The material can potentially remove heat from...
  • Pyrophyllite
    Article - 6 Jun 2002
    Pyrophyllite is soft ceramic material. Its softness allows it to be machines using conventional machining techniques and tools. Applications include machined ceramics for insulators and in tile and...
  • Niobium - An Introduction
    Article - 7 May 2002
    Niobium was first discovered by Hatchett in 1801, but this metal was produced only in 1864, when Blomstrand reduced niobium chloride.
  • Silica - Fused Silica (Silicon Dioxide)
    Article - 2 May 2002
    Fused silica is an amorphous grade of silica known for its low thermal expansion and thermal shock resistance. It is made by melting high purity silica sands and has uses in refractories, investment...
  • Silica - Colloidal Silica (Silicon Dioxide)
    Article - 2 May 2002
    Colloidal silica consists of a stable suspension of tiny silica particles. It has many applications such as refractories, investment casting, abrasives, surfactants, high temperature binders etc
  • Superalloys for Coal Fired Power Generation
    Article - 11 Mar 2002
    Superalloys are emerging as a viable alternative to ceramic filters for clean burning coal power generators. The possibility of creating thin filters with high surface area and limited susceptibility...
  • Tantalum - An Overview
    Article - 23 Jan 2002
    Tantalum is a rare metal with a grey-blue appearance. It is found in about 15% of the world’s pegmatites. Tantalum has several properties that currently make it a valuable commodity.
  • Mullite - An Introduction
    Article - 15 Oct 2001
    Mullites main uses are in refractories and ceramic bodies where it contributes properties such as thermal shock resistance, volume stability and hot strength. It is an aluminosilicate material rarely...
  • Kyanite
    Article - 15 Oct 2001
    Kyanite is an aluminosilicate used predmoninantly for refractories and ceramic bodies. It consists nominally of 60% Al2O3 and 40% SiO2. Al larger irreversible volume expansion makes it useful in...
  • Mullite - An Introduction
    Article - 3 Oct 2001
    Mullite is the mineralogical name for the only chemically stable intermediate phase in the SiO2–Al2O3 system. The mineral rarely occurs in its natural form, and can be found on the Isle of Mull off...

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.
