Materials Sciences
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.
Strong Magnetic Field Converts Nanotube From Metal To Semiconductor And Back
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 nanotube’s electronic structure can be altered in response to a magnetic field. The research team c
Magnetic forces may turn some nanotubes into metals
Research documents first instance of band-gap shrinkage in a semiconductor
A new study, published in today’s 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

Increasing superficial hardening in materials used in aeronautics or biomedicine
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.

Chemist’s technique enables creation of novel carbon nanoparticles
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
New high-tech concrete is lighter, stronger & green
Australian scientists have developed a breakthrough low-cost, lightweight, concrete technology that is set to lower costs and speed up construction projects from residential homes to high-rise buildings.
HySSIL (High-Strength, Structural, Insulative, Lightweight) panels are manufactured using a new low energy, process developed by CSIRO Novel Materials & Processes. Dr Swee Liang Mak, who leads the HySSIL development team at CSIRO says, ’HySSIL is a revolutionary aerated cementitious (cement
