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.

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.

Engineers
at Stanford University have found a novel method for “decorating”
nanowires with chains of tiny particles to increase their electrical and
catalytic performance. The new technique is simpler, faster and
provides greater control than earlier methods and could lead to better
batteries, solar cells and catalysts.

Cornell
materials scientists have developed an inexpensive, environmentally
friendly way of synthesizing oxide crystal sheets, just nanometers
thick, which have useful properties for electronics and alternative
energy applications. Unlike typical oxides, these sheets are conducting,
and could be ideal for use in thermoelectric devices to convert waste
heat into power.

Cog
wheels, threads, machine parts, cranks. and bicycle chains wear out
quickly unless greases and oils help out. But lubricants containing fat
agglutinate or resinify, necessitating cleaning and regreasing. A new
composite material that can be applied as a coating offers a greaseless
solution and also protects against corrosion.

Researchers
in the U.K. grew monolayer graphene sheets on copper foil using
chemical vapor deposition (CVD), then attached them to high-Q silicon
nanomechanical oscillators, which allowed them to measure, for the first
time, the stress and strain shear modulus and the internal friction of
the sheets. The result suggest a new application for CVD-grown graphene.

Delicate
and translucent as a puff of air, yet mechanically stable, flexible,
and possessing very low thermal conductivity—these are the properties of
a new aerogel invented in China. Made from cellulose and silica gel,
the material is 99.98% air-filled pores.

Researchers at Aalto
University in Finland have
developed a new and significantly cheaper method of manufacturing fuel
cells. A
noble metal nanoparticle catalyst for fuel cells is prepared using
atomic layer
deposition (ALD). This ALD method for manufacturing fuel cells requires
60%
less of the costly catalyst than current methods.

Researchers have used candle soot to produce a transparent superamphiphobic coating made of glass. Oil and water both roll off the new coating, leaving nothing behind. It works even when the layer was damaged with sandblasting.

NASA
engineers have produced a material that absorbs on average more than
99% of the ultraviolet, visible, infrared, and far-infrared light that
hits it. The thin layer of multi-walled carbon nanotubes can absorb
light 10 to 100 times better than alternate materials at a given
wavelength, and will be useful for applications like stray-light
suppression.
