The target of the project was to develop new magnetic sensors to help measure process variables in steel production, such as velocity or elongation.
Uniovi developed high sensitive magnetic sensors for a harsh environment.
A non-contact speed-measuring device based on the developed sensor was installed in the continuous annealing line of Aceralia. The system used a magnetic marker and two sensors separated more than 2 cm from the strip, working on a differential principle to impr
A new type of liquid crystal – recently discovered by a research team that includes a Kent State University professor – holds the promise of faster liquid crystal displays at a lower price.
A new liquid crystal phase – the biaxial nematic liquid crystal – which is likely to revolutionize the liquid crystal display technology, has been discovered by three researchers, Dr. Satyendra Kumar, professor of physics at Kent State; Dr. Bharat R. Acharya, of Platytus Technologies, Madison, WI; and Dr
Last July the Mancomunidad de AGUAS DEL AÑARBE (Association of Municipal Councils supplied with water from the Añarbe reservoir) contracted the CIDETEC Research Centre to carry out a study of the corrosive capacity of the water supply treated at the AÑARBE reservoir purification plant and supplied to households in pipes made of various materials. The Mancomunidad de Aguas del Añarbe is made up of Donostia-San Sebastian City Council and the following Town Councils; Rentería, Pasaia, Hernani, Lasarte,
Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory, in collaboration with researchers at the Rutherford Appleton Laboratory in the United Kingdom and Tohoku University in Japan, have discovered evidence supporting a possible mechanism for high-temperature superconductivity that had previously appeared incompatible with certain experimental observations. The finding, which hinges paradoxically on what the scientists observed in a particular material that loses its superconduc
A breakthrough in polymer development means that soon there may be a radical new treatment for people with broken bones – a special kind of material that can ’glue’ the bone back together and support it while it heals.
The material is designed to break down as the bone regrows leaving only natural tissue.
Scientists at CSIRO Molecular Science have developed a biodegradable polymer that can be used in the human body. Not only is it biodegradable and biocompatible, it can be
As if getting to Mars wasn’t hard enough, astronauts also have to worry about what to wear when they arrive. Their concerns are not fashion pundits but exposure to micrometeor sandstorms, radiation, and a hyper-cold climate.
However, three undergraduate students at the University of Alberta – Jennifer Marcy, Ann Shalanski, and Matthew Yarmuch – addressed the problem in Dr. Barry Patchett’s Materials Design 443 class and have published their findings in the Journal of Materials Eng
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 nanotube’s 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 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

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
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
For the last few years scientists at the Nanometer Consortium at Lund University have been able to make nanowires, tiny wires just a few millionths of a millimeter “thick” and made of semiconducting material of great potential in the electronics industry. Now they have managed to produce “nanotrees,” in fact tiny forests on the same scale.
This is described in an article (“Synthesis of branched ‘nanotrees’ by controlled seeding of multiple branching events”) in the journal Nature Materials,

In a development that brings the promise of mass production to nanoscale devices, Lawrence Berkeley National Laboratory scientists have transformed carbon nanotubes into conveyor belts capable of ferrying atom-sized particles to microscopic worksites.
By applying a small electrical current to a carbon nanotube, they moved indium particles along the tube like auto parts on an assembly line. Their research, described in the April 29 issue of Nature, lays the groundwork for the high-throughput
