Materials science and engineering is grounded in an understanding of why materials behave the way they do. Researchers study ways to make materials - how they can be made light yet very strong, such as high-strength aluminum alloys for jet aircraft, for instance. Mechanical strength, electrical, optical, and magnetic properties, to name a few, are the bases of many new potential products. Research is conducted on ceramics, polymers, and semiconductors, as well as old standbys, metals and glasses. Areas that benefit from advances in materials research are biomedical engineering, computing, the auto and aircraft industries, and biotechnology.

Modern research in chemistry, physics, materials science, and biology is increasingly focused on nanoscale systems and nanotechnology. Basically, this is the study of systems, materials and phenomena where the important length scale is conveniently measured in nanometers (nm). Much of modern chemistry is performed on the nanoscale and nearly all of molecular biology and biochemistry, as well as a lot of materials science.

In the mix Research aims to produce energy on the farm (http://news-info.wustl.edu/tips/page/normal/11547.html) April 15, 2008 -- David Kilper/WUSTL Photo Muthanna Al-Dahhan (left) and graduate student Rajneesh Varma are researching effective ways to take agricultural waste and make biofuel out of it. Engineers at Washington University in St. Louis, using an impressive array of imaging and tracking technologies, have determined the importance of mixing in anaerobic digesters for bioenergy production and animal and farm wastes treatment. They are studying ways to take "the smell of money," as farmers long have termed manure's odor, and produce biogas from it.

Chemists make first boron nanowhiskers; 'Little shavers' could prove key in nanoelectronics (http://news-info.wustl.edu/tips/2002/science-tech/otten.html)
June 2002 - They're cute little shavers, and they could play a key role in the "small" revolution about us. Chemistry graduate student Heng Yu and William E. Buhro, Ph.D., professor of chemistry in Arts & Sciences, examine nanowire specimens in an inert-atmosphere glove box, which stores moisture- and oxygen-sensitive chemicals. The glove box allows manipulation of sensitive reagents and nanostructured materials in a continuously scrubbed nitrogen atmosphere.They're boron nanowhiskers, the world's first such crystalline nanowires, made by chemists at Washington University in St. Louis.

Advances in nanotechnology by William E. Buhro, Ph.D., impact realms from sports to electronics (http://record.wustl.edu/archive/2001/11-09-01/people.html)
Nov. 9, 2001 - William E. Buhro, Ph.D., professor of chemistry in Arts & Sciences, sweats the small stuff. In his world, it's all small stuff. That's because Buhro and his group are immersed in the Lilliputian world of nanoparticles and nanowires, which are invisible to the naked eye and hold promise in making stronger and tougher materials for a wide range of products and applications, and for enabling advances in nanoelectronics.
