Nature Materials
The
smallest piece of ice reveals its true nature
Collaborative
research between scientists in the UK and Germany (published in this
week's Nature Materials) has led to a breakthrough in the understanding of
the formation of ice. Dr. Angelos Michaelides of the London Center for
Nanotechnology (formerly of the Fritz-Haber Institut der Max-Planck
Gesellschaft in Berlin) and Professor Karina Morgenstern of the Leibniz
University Hannover have combined experimental observations with
theoretical modelling to reveal with unprecedented resolution the
structures of the smallest pieces of ice that form on hydrophobic metal
surfaces.

A
review of microcantilevers for sensing
applications
Microelectromechanical Systems (MEMS) have come
into existence only in the last decade. Microcantilevers are the most
simplified MEMS based devices. They are of significant interest as they
have potential applications in every field of science ranging from
physical and chemical sensing to biological disease diagnosis.

adhesive sticks better than a gecko's foot
Mimicking the
agile gecko, with its uncanny ability to run up walls and across ceilings,
has long been a goal of materials scientists. Researchers at Rensselaer
Polytechnic Institute and the University of Akron have taken one sticky
step in the right direction, creating synthetic "gecko tape" with four
times the sticking power of the real thing.

professor's discovery leads to $1.2 million hydrogen grant
A
unique discovery being published today by University of Tennessee
Knoxville scientists has led to a $1.2 million grant to help overcome
roadblocks facing the wide-scale use of hydrogen as a national energy
source. Researchers found that by adding small amounts of bismuth to an
extremely thin film of lead atoms, they could fine-tune the physical
properties of the newly made "quantum alloy." The approach can be also
applied to hydrogen fuel cell storage research.

flickering reveals single-molecule rendezvous
In this week's
issue of Science, French and US researchers describe a new technique that
allowed them to zoom in and observe quantum quasiparticles called excitons
on individual carbon nanotubes. The team, which was led by Rice University
chemist Bruce Weisman and University of Bordeaux physicist Laurent Cognet,
found that each exciton travels about 90 nanometers and visits around
10,000 carbon atoms during its 100-trillionth-of-a-second
lifespan.
