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.

Plants Provide Model for New Shape-changing Materials

Over the next 17 months, Virginia Tech will lead a team of researchers exploring the development of a new class of materials that will use plant protein structures in an attempt to mimic biological systems. The Defense Science Office of the Defense Advanced Research Project Agency (DARPA) is funding the $2.1 million project.

DARPA is specifically interested in a group of hard polymers called nastic materials. In biology, nastic refers to the natural movement of plants in response to

Space-tech at the Paralympics

At the 2004 Paralympics this week, Wojtek Czyz, the world record holder for long jump, will be trusting in space technology and expertise to help him win his first Olympic medal. For the competition, parts of the prosthesis he will be using are made from material designed for space to make it both stronger and lighter.

Czyz lost part of his left leg in a sports accident three years ago and in order to continue his passion for “everything that has to do with sport”, this meant that h

Rice refining production of pure nanotube fibers

Pioneering fiber production methods similar to those of Kevlar(R), Zylon(R)

Rice University scientists are refining pioneering chemical production methods used to make pure carbon nanotube fibers. Research appearing in tomorrow’s issue of the journal Science describes the scalable production techniques, which yield highly aligned, continuous macroscopic fibers composed solely of single-walled carbon nanotubes (SWNTs), the type of carbon nanotubes with the best mechanical and trans

Radiation after lumpectomy may be unnecessary for many older women

Tamoxifen alone may adequately control breast cancer, avoiding side effects

Older women treated with tamoxifen after removal of early-stage breast cancer by lumpectomy may safely be able to avoid radiation therapy and its unpleasant side effects. In the Sept. 2 New England Journal of Medicine, investigators from several major cancer research groups report that adding radiation to post-surgical tamoxifen treatment of women age 70 or older does not improve survival, has minimal impact o

Supercool! Model unscrambles complex crystallization puzzle

To the wonderment—and the befuddlement—of scientists, the patterns that form as plastics, metals and many other materials crystallize can vary incredibly, ranging from sea-urchin-like spheres to elaborate tree-like branches.

Now, Hungarian and National Institute of Standards and Technology scientists report in the September issue of Nature Materials* that they have developed a way to predict the polycrystalline microstructures that will form as complex liquid mixtures cool and

Groundbreaking innovations usher an exciting phase in the plastics materials industry

Technical Insights plastics materials – Emerging technology and trends analysis

Economical, performance-focused plastics materials application development is dependent not only on leveraging traditional, well-defined ‘cost-performance’ parameters, but also on understanding the strategic nuances essential for sustaining long-term growth.

“Adherence to regulatory legislation – particularly in the areas of continuous improvement in size and weight reduction – is one of th
