This is the tale of two biological substances-cells from mammals and bacteria. It's a story about the havoc these microscopic entities can wreak on all manner of surfaces, from mighty ships to teeth and medical devic...
If you're of a certain age, you'll remember Buckminster Fuller's distinctive
"geodesic domes" - soccer-ball-shaped structures that the late futurist
envisioned as ideal human domiciles. Tel
Aviv University chemists remember them too - and are now putting them to
use in the treatment of multiple sclerosis.
Even small devices need power, and much of that juice comes from fuel cells.
As these devices become even smaller, the rush is on to find more efficient
ways to power them.
The primary application of geopolymer technology is in the development of
reduced CO2 construction materials. Recognised as an alternative to traditional
materials such as Portland based cements geopolymers represent a movement towards
more environmentally friendly engineering.

Europe has announced the availability of the Symyx Screening Pressure Reactor
(SPR), a high-throughput research system that enables up to a 100-fold increase
in the speed of screening and optimising catalysts and catalytic processes.
In comparison to other battery types, lithium-ion batteries have some major
advantages. For one, they are the most efficient battery on the market right
now. In order to make a decisive improvement on today's technology, BASF,
together with other companies, is investing in further research and development
of lithium-ion batteries.
Photodetectors -- devices found in cell phones, digital cameras and other consumer gadgets that utilize photoconducting materials -- are a green technology in performance (converting light into electricity), but the manu...
Angela M. Belcher, Ph.D., a noted scientist from Massachusetts Institute of
Technology (MIT), will deliver the Keynote Address in Nanoscience here today
at the American
Chemical Society's 237th National Meeting.
Single oxygen atoms dancing on a metal oxide slab, glowing brighter here and
dimmer there, have helped chemists better understand how water splits into oxygen
and hydrogen. In the process, the scientists have visualized a chemical reaction
that had previously only been talked about. The new work improves our understanding
of the chemistry needed to generate hydrogen fuel from water.
A team of researchers from Brookhaven, Yeshiva University, and the University of Delaware has demonstrated a new, highly efficient way to synthesize the nanocatalysts based on palladium and gold.
