• Polystyrene nanosphere dyes

    Polystyrene nanospheres replace toxic dyes to produce structural colours

    Materials World magazine
    With increasing concerns about the use of traditional dyes on the environment, materials that use polysytene nanospheres rather than toxic dyes to produce colour have been the subject of research by scientists at the University of Southampton, UK. The sphere size controls the wavelength which light is reflected and scattered from the film, offering new possibilities for structural colours. The materials have already attracted the interest of Unilever, Kodak, Merck and Degussa for applications ranging from packaging to automotives.
  • Biometric laser scanner

    Biometric fingerprints for anti-counterfeiting

    Packaging Professional magazine
    ProteXXion, launched by Bayer Technology Services in Germany, is a security and tracking device that uses the biometric fingerprints of individual surfaces to counter fraud in items ranging from packaging to passports. ProteXXion encompasses project management, installation and servicing of the laser surface authentication (LSA) technology invented at Imperial College London, UK. Laser surface authentification combined with RFID tracking device tags could provide an all-encompassing anti-fraud solution. Trials have been conducted on pharmaceutical and tobacco packaging using static scannes on production lines that move up to four metres per second.
  • Flames

    Flame-retardant polymer

    Materials World magazine
    Scientists from the University of Massachusetts Amherst, USA, have created a flame-retardant synthetic polymer that does not require conventional and potentially harmful halogen additives. The team aims to apply the material in the interior of aircraft and ships.
  • Supraspheres

    Mouldable metals' created using nanocrystals

    Materials World magazine
    A method of assembling metal nanoparticles into a clay-like structure that can be moulded and fired has been developed by researchers at Northwestern University, Chicago, USA. Paternal applications include flexible electronics.
  • Plasma-coated stent

    3D plasma coating technique prevents stents from clogging

    Materials World magazine
    Researchers at the University of Ulster, UK, have developed a 3D plasma coating technique to prevent stents from developing neointima, where thick muscle tissue grows over the surface, leading to the blood vessel narrowing again. Thin films of carbon, ceramics and platinum are coated using the new method to prevent clogging.
  • Air gaps microprocessor

    Air-gap insulation method increases chip speed

    Materials World magazine
    Air gap insulation between copper wires in microprossesors can increase chip speed making them more efficient, say researchers at IBM.
  • Carbon nanotube array

    Creating longer nanotubes

    Materials World magazine
    Attempts to grow carbon nanotubes have had limited success. However researchers from the Universiy of Cincinnati in the USA, claim to have used a novel composite catalyst made of alternating layers of metal and ceramics, to grow the world's longest array of aligned carbon nanotubes carbon nanotubes that have high mechanical, electrical and optical properties.
  • Starpack 2007 – A star-studded evening for packaging technologists

    IOM3
    Packaging designers and technologists came together for the 2007 Starpack Awards Ceremony, held at the National Motorcycle Museum in Birmingham.
  • Copper alloy moulds

    Copper increases efficiency in injection moulding

    Packaging Professional magazine
    Replacing traditional steel moulds with those made from copper alloys could make injection moulding of plastic packaging more productive, according to research led by UK-based Copperplas International Ltd. Project Aimtech aims to reduce cycle time and improve finish quality to increase competiveness with the rapidly developing Chinese supply chain. Copper alloy moulds are five to six times more thermally conductive than steel for injecting molten plastic at high pressure.
