Materials management deals with the research, development, manufacturing and processing of raw and industrial materials. Key aspects here are biological and medical issues, which play an increasingly important role in this field.
innovations-report offers in-depth articles related to the development and application of materials and the structure and properties of new materials.
More durable helmets, vests, ski-sticks and various other fibre-glass plastic products are close to becoming a reality. Provided, of course, the manufacturers apply new technology – the one developed by the Chernogolovka scientists supported by the Russian Foundation for Basic Research and the Foundation for Assistance to Small Innovative Enterprises (FASIE).
When fibre-glass plastic products were first introduced to the market, the applicability of the material seemed truly unlimited. Late
By threading a magnetic field through a carbon nanotube, scientists have switched the molecule between metallic and semiconducting states, a phenomenon predicted by physicists some years ago, but never before clearly seen in individual molecules. In the May 21 issue of the journal Science, researchers from the University of Illinois at Urbana-Champaign present experimental evidence that a nanotubes electronic structure can be altered in response to a magnetic field. The research team c
Research documents first instance of band-gap shrinkage in a semiconductor
A new study, published in todays issue of the journal Science, finds that the basic electrical properties of semiconducting carbon nanotubes change when they are placed inside a magnetic field. The phenomenon is unique among known materials, and it could cause semiconducting nanotubes to transform into metals in even stronger magnetic fields.
Scientists found that the “band gap” of semiconductin

Researchers at the Public University of Navarre and the Navarre Industry Association research centre have managed to increase by 30 to 500 % the superficial hardness and resistance to wear of metals and V5Ti alloys by means of applying nitrogen. These results could be of great use for different industrial applications in which these types of materials are employed such as in the aeronautic and biomedical sectors.

Wooley technique ’linchpin’ to success
Using a technique pioneered by Washington University in St. Louis chemist Karen Wooley, Ph.D., scientists have developed a novel way to make discrete carbon nanoparticles for electrical components used in industry and research.
The method uses polyacrylonitrile (PAN) as a nanoparticle precursor and is relatively low cost, simple and potentially scalable to commercial production levels. It provides significant advantages over existing
