Bioglass from Concept to Clinic: A 40-year Retrospective

By / June 24, 2009

This ACerS video is a lecture by Larry Hench given at the PACRIM8 Conference in June 2009 in Vancouver. Hench has been at the forefront of the revolution that has occurred in the past four decades in the field of bioactive glass. First discovered in 1969, these materials provided the first alternative to bioinert materials.…

The world’s first controllable molecular gear

By / June 19, 2009

Researchers in Singapore have advanced the science of nanotechnology by becoming the first in the world to invent a molecular gear of only 1.2 nm in size whose rotation can be deliberately controlled. This achievement was published on June 14 in Nature Materials. The gear is made of carbon compounds and can freely rotate around…

There could be a virus in your battery

By RussJordan / June 7, 2009

But don’t worry. It is a common bacteriophage. It can infect bacteria but is harmless to humans. You might find this virus someday in the battery of your plug-in hybrid car. What has happened is that MIT researchers now can genetically engineer viruses to build the anodes and cathodes of a lithium-ion battery. These batteries…

ACerS launches new glass research journal

By / May 31, 2009

After nearly a year of behind-the-scenes planning, the American Ceramic Society just announced that it is launching a new journal on advanced glass research. This new peer-reviewed quarterly will be called the International Journal of Applied Glass Science. The journal’s debut is timely as new generations of glass and glass-related materials are increasingly being called…

DOE lights up Biofuels with $800 million in new funding

By / May 5, 2009

DOE Secretary Steven Chu is keeping the jobs/energy ball rolling with an announcement today that the agency has allocated $786.5 million from the American Recovery and Reinvestment Act to accelerate advanced biofuels R&D and commercial-scale biorefinery demonstration projects. There are many materials research and engineering angles to this, but the $110 million for “fundamental research”…

Video of the week – Putting a wrapper on nanotubes increases luminescence

By / April 8, 2009

A team from UConn’s Nanomaterials Optoelectronics Lab at the Institute of Materials Science has discovered a nifty way to increase the photoluminescence of single-walled carbon nanotubes by wrapping the tubes with a sleeve made from a Vitamin B2 analog. The wrapping prevents defects caused by oxygen and renders them much more useful for nanotech applications.…

Nanotube aerogel sheets – better than real muscle?

By / March 20, 2009

Aerogels are incredibly lightweight (nearly lighter than air) and strong materials, and one of this blog’s most popular posts is a video demonstrating some amazing aerogel properties. Although it’s not a new material, I’ve felt that only recently have R&D techniques been able to mature enough to match aerogel’s capabilities. Indeed, now there is news…
