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.

Latex means environmentally friendly packaging

For several years, Caisa Andersson has been trying to create a better barrier against moisture and oxygen in our food packaging. On December 20, she will submit her doctoral dissertation at Karlstad University in Sweden.

Latex has long been used for various types of surface treatment of paper. In recent years, interest has been focused on the polymer’s characteristic of forming a protective coating on the surface of paper.

Nanoparticles could aid biohazard detection, computer industry

Nanotechnology could make life easier for computer manufacturers and tougher for terrorists, reports a Purdue University research team.

A group led by Jillian Buriak has found a rapid and cost-effective method of forming tiny particles of high-purity metals on the surface of advanced semiconductor materials such as gallium arsenide. While the economic benefits alone of such a discovery would be good news to chip manufacturers, who face the problem of connecting increasingly tiny com

Komfortable Kinderschuhe dank Fußdummy und Messsocke

nnovationen aus der industriellen Gemeinschaftsforschung

Pro Jahr gehen in Deutschland etwa 22 Mio. Paar Kinderschuhe über die Ladentheke. Rund 30 Prozent davon stellen deutsche Firmen her. Neben seinem modischen Aussehen und seiner richtigen Passform ist die Fähigkeit zur Wärme- und Feuchtigkeitsregulation maßgeblich für den Komfort eines Schuhs. Die Füße sollen warm und trocken bleiben und vor äußeren Einwirkungen geschützt werden. Der Abtransport des Fußschweißes durch Socke und S

Planes leading edges in a single piece

The basque company SK10, which works in the integration of aeronautical structures, has given a significant step forward in its innovation range within compound materials of carbon fibre.

Recently, SK10 has signed with the company EADS-CASA a contract for the development, industrialisation and subsequent mass production of the leading edges of the horizontal stabiliser for the new aircraft Falcon F7X, of the French company DASSAULT.

Molecular Film on Liquid Mercury Reveals New Properties

A team of scientists from the U.S. Department of Energy’s Brookhaven National Laboratory, Harvard University, and Bar-Ilan University in Israel have grown ultrathin films made of organic molecules on the surface of liquid mercury. The results, reported in the November 15, 2002, issue of Science, reveal a series of new molecular structures that could lead to novel applications in nanotechnology, which involves manipulating materials at the atomic scale.

Engineering researchers demystify fatigue failure in polysilicon used in MEMS devices

The success of many advanced technologies that use devices such as sensors and actuators, including gyroscopes and optical devices, depends on microscopic components called microelectromechanical systems (MEMS) devices made of polycrystalline silicon (polysilicon). Researchers at Case Western Reserve University report in the November 8 issue of Science that miniature micron-sized polysilicon laboratory specimens subjected to cyclic tension/compression loading undergo fatigue, and could ultimately fa

Researchers produce strong copper that retains ductility

Extreme cold and high heat help optimize the metal’s microstructure

Combining old-fashioned metal-working techniques with modern nanotechnology, engineers at The Johns Hopkins University have produced a form of pure copper metal that is six times stronger than normal, with no significant loss of ductility.

The achievement, reported in the Oct. 31 issue of the journal “Nature,” is important because earlier attempts to strengthen a pure metal such as copper have almost always

New nanoparticle coating mimics dolphin skin Prevents ’biofouling’ of ship hulls

Dolphins, long considered the second-smartest species on the planet, recognize one another by name, possess a distinct concept of “self’ and, it turns out, have some surprisingly good ideas about techniques for keeping the hulls of maritime ships clean.

Karen L. Wooley, Ph.D., professor of chemistry at Washington University in St. Louis, has noted the shape and texture of dolphin skin and how it naturally prevents marine creatures from clinging to dolphin skin. The observation fits into h

Bloodworm’s way with copper likely provides paradigm for new materials

Researchers report in the Oct. 11 “Science” the first detection of a living organism that makes a copper-containing mineral structure as part of its skeleton. The finding is remarkable because the amount of copper detected in the jaw tip of the marine bloodworm would normally be toxic to an organism.

The researchers determined that copper also occurs in non-mineral form in the bloodworm jaw where it may act as a structural element in cross-linking long chains of fibrous proteins. According

Better metal forming: magnetic pulses “bump” metal into shape

A process developed at Ohio State University for shaping metal parts using magnetism has reached a new milestone — one that may cut manufacturing costs and help preserve the environment.

The process could also expand manufacturers’ choice of available metals, and enable the use of aluminum parts in lighter, fuel-efficient automobiles.

Glenn S. Daehn, professor of materials science and engineering, and his colleagues pioneered hybrid electromagnetic metal forming in 1999, while col
