    High speed patterning of hydrogels

    Materials World magazine
    Direct laser interference lithography can speed up micropatterning of hydrogels for biomedical applications with improved resolution, says Dr Andrés Lasagni in Germany.
  • Surfaces on the London Underground may be an application area for the anti-pathogenic nanomaterial

    Anti-pathogenic refractory material

    Materials World magazine
    A multifunctional nanomaterial to combat viruses, bacteria and fungi is under investigation by scientists at Intrinsiq Materials, headquartered in Dublin, Ireland. They are exploring its application within and on the surface of products such as disposable medical devices, filtration media, facemasks and hygienic surfaces.
  • IOM3 2009 Award and Prize winners announced

    The recipients of the 2009 Institute Awards and Prizes have been decided. The premier award winners will receive their awards at a ceremony on 7 July.
  • Special issue on developments in superalloys

    Materials Science & Technology Division
    The February 2009 issue of Materials Science and Technology contains the proceedings of the symposium on Developments in superallys held in memory of the late Professor Malcolm McLean.
  • A cylinder coated with Hardide

    Coating titanium

    Materials World magazine
    A process for imparting wear, abrasion and chemical resistance to titanium components has been developed, say researchers at Hardide Coatings, based in Bicester, UK. The Hardide-T coating, made from nanostructured tungsten carbide, is applied using low temperature chemical vapour deposition (CVD).

    Smart detection of corrosion

    Materials World magazine
    Researchers in the USA are developing a smart coating to enable early detection of rust or corrosion in metals.
  • Chemical vapour deposition at speed

    Materials World magazine
    Synthesis and screening of thin film samples on glass may become faster using modified atmospheric pressure chemical vapour deposition equipment developed at University College London (UCL), UK. This is combined with rapid automated analysis of each cell to identify new and suitable phases.

    Surface solution for writing nanodata

    Materials World magazine
    A carbon nanotube (CNT) probe tip, with silicon oxide outer layer for wear resistance, could enable ultrahigh density data storage. The ‘nanopencil’ can write bit sizes as small as 6.8nm onto ferroelectric films, while the silicon oxide makes it less prone to bending or buckling.
  • Light emitting diode emission as a current passes through the carbon-nanotube coated cotton

    Smart cotton for biomonitoring

    Materials World magazine
    A conductive cotton yarn woven into soft fabrics could have health monitoring capabilities by acting as an intergrated sensor. The thread is coated in carbon nanotubes and is said to produce smart textiles with better flexibility, durability and mobile comfort than metal and optical fibres.
