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.

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.

White-light
quantum dots made from cadmium selenide can convert blue light produced
by a light-emitting diode into a warm white light similar to that
generated by an incandescent bulb. But their performance has been poor
until recent development breakthroughs have improved efficiency from
just 3% originally to as high as 45%.

Researchers
in Switzerland have created a new nanocomposite that combines the best
features of graphene and protein fibrils, the two main ingredients of a
specialized type of paper. The material is created in much the same way
as normal cellulose paper, but the properties are far different. Shape
memory, electrical conductivity, and hydrophobia all offer interesting
application possibilities.

One
exhale and a new device from researchers at Stony Brook University in
New York could screen for anything from diabetes to lung cancer. Based
on a sensor chip built from electrospun nanowires that can detect minute
amounts of chemical compounds, the device has yet to reach clinical
trials. But its inventors anticipate the device to someday cost only
$20.

Development
of new therapies for a range of medical conditions, including sports
injuries and heart attacks, could depend on a new production-scale
microthread extruder developed by a team of graduate students and
biomedical engineering faculty at Worcester Polytechnic Institute. The
microthreads would support tissue regeneration, wound healing, and cell
therapy.

A
team of chemical engineers at the University of Massachusetts Amherst
has found an inexpensive way to achieve a 75% yield from biomass for the
formation of the chemical p-xylene, a key ingredient used to make
plastic bottles. This chemical is normally made using petroleum.
