Metallic
Glass Yields Secrets Under Pressure
NEW
Mar. 16,
2010
Metallic
glasses are emerging as potentially useful materials at the
frontier of materials science research. They combine the
advantages and avoid many of the problems of normal metals and
glasses, two classes of materials with a very wide range of
applications. For example, metallic glasses are less brittle than
ordinary glasses and more resilient than conventional metals.
Metallic glasses also have unique electronic behavior that
scientists are just beginning to understand.

The
Smell of Salt Air, a Mile High and 900 Miles Inland
NEW
Mar. 10,
2010
The smell of
sea salt in the air is a romanticized feature of life along a
seacoast. Wind and waves kick up spray, and bits of sodium
chloride – common table salt – can permeate the air.
It is believed that as much as 10 billion metric tons of chloride
enters the air mass through this process each year, but just a
tiny fraction – perhaps one-third of 1 percent – does
anything but fall back to the surface.

First
Temperate Exoplanet Sized Up
NEW
Mar.
18, 2010
Combining
observations from the CoRoT satellite and the ESO HARPS
instrument, astronomers have discovered the first “normal”
exoplanet that can be studied in great detail. Designated
Corot-9b, the planet regularly passes in front of a star similar
to the Sun located 1500 light-years away from Earth towards the
constellation of Serpens (the Snake).

Absorbing
Hydrogen Fluoride Gas to Enhance Crystal Growth
Dec. 10,
2009
Two
scientists at the U.S. Department of Energy’s (DOE)
Brookhaven National Laboratory have developed a method to control
the buildup of hydrogen fluoride gas during the growth of
precision crystals needed for applications such as
superconductors, optical devices, and microelectronics. The
invention — by Vyacheslav Solovyov and Harold Wiesmann and
recently awarded U.S. Patent number 7,622,426 — could lead
to more efficient production and improved performance of these
materials.

Lockheed
Martin C-5M Super Galaxy Is 'Effective, Suitable And Mission
Capable' For USAF Operations
NEW
Mar. 10,
2010
The Air
Force Operational Test and Evaluation (OT&E) Center has rated
the Lockheed Martin [NYSE: LMT] C-5M as "effective, suitable
and mission capable" based on results from OT&E testing
completed in January 2010. The OT&E phase spanned four
months, evaluating various performance aspects to validate the
capability and reliability of the C-5M. These positive test
results enable the Super Galaxy to continue to support critical
missions flown in support of world-wide operational
contingencies.
