  • Titanium - Corrosion by Water
    Article - 5 Feb 2002
    Titanium is highly resistant to corrosion by water, steam and seawater, except at elevated temperatures. Other corrosion mechanisms such as stress corrosion cracking, corrosion fatigue, biofouling,...
  • A Summary of Aluminum Titanate
    Article - 4 Feb 2002
    At temperatures greater than 1350 °C, the solid-state reaction of titania and alumina leads to the synthesis of aluminum titanate. Depending on its reactivity, the synthesized powder can be sintered...
  • Tungsten Carbide - An Overview
    Article - 21 Jan 2002
    Scheele discovered “Tungsten” in 1781; however, it took 150 years more before the efforts of Scheele and his successors led to the use of tungsten carbide in the industry.
  • Stainless Steel - Design Considerations
    Article - 2 Jan 2002
    Properties such as high thermal expansion, low thermal conductivity and low machinability compared to other metals need to be taken into account when designing with stainless steels. Many of these...
  • Stainless Steel - Surface Contamination in Fabrication
    Article - 2 Jan 2002

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.
