An
important chemical species, molecular oxygen is linear, has an
anisotropic shape, and spins from two unpaired electrons. However, until
now, we didn’t know how these properties influenced important oxidation
reactions. Researchers in Japan have now reported development of the
world's first molecular oxygen beam that can designate the alignment of
the molecular axis and spin direction.

U.S. factories produce
about 75% of what the country consumes, but the right decisions by both
business and political leaders could push that to 95%, say University of
Michigan researchers.

A Georgia Institute of Technology research team has developed a novel
technology that could change how industry designs and casts complex,
costly
metal parts. This new casting method makes possible faster prototype
development times, as well as more efficient and cost-effective
manufacturing
procedures after a part moves to mass production.

University
at Buffalo researchers are making significant progress on rust-proofing
steel using a graphene-based composite that could serve as a nontoxic
alternative to coatings that contain hexavalent chromium, a probable
carcinogen.

Joshua
Zide has spent nearly a decade engineering nanomaterials using
molecular beam epitaxy. His particular area of expertise are
metalllic-semiconductor nanocomposite for use in electronics, and he is
now working on a variation of epitaxy that he hopes will bring the
materials deposition technique to the production line for the first
time.

The
U.S. Army Research Laboratory-led Army ManTech program has achieved a
breakthrough in the ability to process thermoplastic-based composites for
use in the helmets of soldiers. The new material grades have produced
several types of head protection, each of which saves at least
one-quarter the weight and up to 35% higher tolerance from fragmenting
munitions.

Wet
chemical processes or vacuum plasma processes are typically used for
coating applications in industry. Both have drawbacks: vacuum units are
expensive and time-consuming, and wet chemistry is energy-intensive and
environmentally challenging. Researchers have recently developed a new
kind of plasma coating process that works at ambient pressure.

Camera
maker Canon Inc. is moving toward fully automating digital camera
production in an effort to cut costs—a key change being played out
across Japan, a world leader in robotics. According to the company
spokesman, counting on machines can help preserve the country's
technological power.

Two
recent studies that tested two ways to protect autoworkers from injury
found letting autoworkers sit while they reach into a car's interior to
perform assembly could help prevent shoulder and back strain. But a
possibly better overall solution the researchers suggested might be to
tilt the entire car so that workers can stand up.

Gallium
nitride, a semiconductor material found in bright lights since the
1990s, is used in wireless applications because of its high efficiency
and high voltage operation. However, it’s difficult to remove heat from
GaN electronics, which limits applications and markets. Researchers at
the University of California, Riverside, have made a material from
graphene that does the job, and it looks a lot like a patterned quilt.
