  • Ageing of Composites
    Article - 27 Aug 2001
    Designers are sometimes reluctant to use fibre reinforced plastic composites as the long term effects of factors such as loading and environmental effects. This article looks at these effects and how...
  • Gobel X-Ray Mirrors
    Article - 23 Aug 2001
    Gobel mirrors are special mirrors designed for the reflection of x-rays. Produced using pulsed laser deposition they have advantages such as increased primary intensity, more forgiving in the area of...
  • Self Propogating High Temperature Synthesis of Magnetic Materials
    Article - 31 Jul 2001
    SHS is a process where materials react during a rapid solid state spontaneous reaction at very high temperatures. The rapid heating and cooling and elevated temperatures allow the production of novel...
  • Low Cost Iron-Based Alloy for Valve Inserts
    Article - 20 Jun 2001
    A new iron-based alloy (W77T6) has been developed for valve seat inserts. It evolved as an economical alternative to cobalt-based alloys which gained favour when new fuels were introduced that burned...
  • Rheology Testing for Ceramics
    Article - 12 Jun 2001
    Rheology testing of ceramic materials can now be performed and applied to production situations such as extrusion processes. This device has been designed for applications from earthenware to advanced...
  • Superplastic Forming of Dental Implants
    Article - 8 Jun 2001
    Superplastic forming is an alternative and novel method for producing dental implants. It is capable of producing complex prostheses that are lighter, more comfortable and stronger than similar...
  • Hydroforming Techniques
    Article - 8 Jun 2001
    Hydroforming is a forming process that uses fluid pressure in place of punches and dies. It can form complex parts that would otherwise require several punched and welded pieces. It is a process of...
  • Hydrogenated Nitrile Rubber
    Article - 7 Jun 2001
    Hydrogenated nitrile rubber (HNBR) is a viable alternative to polychloroprene for many automotive applications such as timing belts, seals and hoses. It has excellent mechanical, thermo-oxidative and...
  • Polyurethane Linked to Windscreen Fogging
    Article - 6 Jun 2001
    Fogging of car windscreens has been linked to polyurethanes by analysing the chemicals present on the windscreen. Amines associated with PUs lead to this conclusion, while no evidence was found to...
  • Porous Silicon as a Biomaterial
    Article - 5 Jun 2001
    Porous silicon has semiconducting properties as well as displaying bioactivity. This makes it potentially a useful material for electronic implant devices. Properties and production are described.

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.
