Big Steps Toward Controlled Structure of Nanomaterial Production
From
Princeton Plasma Physics Laboratory, March 8, 2018, by John Greenwald:
"Scientists
from U.S. Department of Energy's (DOE) Princeton Plasma Physics
Laboratory (PPPL) have developed the diagnostic tools that are being
used to advance an improved and integrated understanding of plasma-based
synthesis - a widely used but poorly understood tool for creating
nanostructures. PPPL scientists and collaborators outline, in several
published papers, recent research that could help to develop
controllable and selective fabrication of nanomaterials with prescribed
structures. Researchers report unique observations of the synthesis in
carbon plasma generated by an electric arc in situ, or as the process unfolds. Three papers break new ground in unraveling the poorly understood arc synthesis process."

Additive Manufacturing: Scientific and Technological Challenges, Market Uptake and Opportunities
From Materials Today, Vol. 21, Issue 1, January-February 2018, by Syed A.M. Tofail et al.:
Additive
manufacturing (AM) uses a 'layer-by-layer' approach to
manufacturing. AM materials include metals, ceramics and polymers
as well as composites, hybrids, and functionally graded materials
(FGMs). The continuing challenge is making functional objects from these
materials. Additive manufacturing is strongly supported to become
one of the main production engineering processes in industry. This
study reviews the state of the art in AM.

Superalloy Surface Treatment for Improved Performance of Power Turbines
From
Tech Briefs, February 1, 2018, by National Energy Technology Laboratory:
"To produce power more efficiently and
cleanly, the next generation of power turbines will have to operate at
extreme temperatures and pressures. While the use of protective thermal
barrier and bond coatings on turbine blades has resulted in significant
improvements in superalloy performance including thermal, oxidative, and
mechanical protection, these coatings still allow for oxygen diffusion
and subsequent reaction with the underlying substrate. A surface
treatment process was developed in which reactive metal elements are
applied directly to the alloy substrate prior to bond-coating, resulting
in reduced oxidation. Further, the process significantly increases
corrosive resistance of nickel-based superalloys."

Researchers Discover New Lead-Free Perovskite Material for Solar Cells
From
Brown University, February 13, 2018:
"
Researchers at Brown University and
University of Nebraska - Lincoln have come up with a new titanium-based
material for making lead-free, inorganic perovskite solar cells. They
show that the material can be a good candidate, especially for making
tandem solar cells - arrangements in which perovskite cells are placed
on top of silicon or another established material to boost the overall
efficiency. Researchers used a high-temperature evaporation method to
prepare the films, but the team is investigating alternative methods.

Researchers Create First-Ever Light-Emitting Nanoantennas
From
ITMO University (Russia), February 12, 2018
:
"
Young scientists from
ITMO University have developed a new type of
nanoscale light source based on halide perovskites. The nanosources are
subwavelength nanoparticles which serve both as emitters and
nanoantennas capable of amplifying light emission inherently without
need for additional devices. Moreover, perovskites enable tuning of
emission spectrum throughout a visible range by varying the composition
of the material. This makes the new nanoparticles a promising platform
for creating compact optoelectronic devices such as optical chips,
light-emitting diodes, or sensors.
They
synthesized perovskite films and then transferred material particles from the film surface to another substrate
using
pulsed laser ablation

Flat-packed Optical Components
From
A*STAR Research (Singapore), February 22, 2018:
"
Surfaces that efficiently redirect the
propagation of light have been developed by A*STAR researchers.
Reseachers at A*STAR Data Storage Institute and Nanyang Technological
University have invented compact and light-weight optical components
that could be integrated into portable optoelectronic devices. The team
achieves efficient optical channeling at any desired angle using a
metasurface comprising an array of asymmetric nanoantennas. Researchers
demonstrated this concept experimentally by etching their nanoantenna
array design into a thin film of titanium dioxide on a glass substrate.
With this novel approach they were able to bend more than 50 per cent of
the energy of an incoming beam of green light at an angle of up to 73
degrees.

Monocrystalline Silicon Thin Film for Cost-cutting Solar Cells have 10X Faster Growth Rate
From Tokyo Institute of Technology (Japan), March 19, 2018:
"A research team from Tokyo Tech and
Waseda University have successfully produced high-quality thin film
monocrystalline silicon with a reduced crystal defect density down to
the silicon wafer level at a growth rate that is more than 10 times
higher than before. The grown film can easily be peeled off using the
double-layer porous Si layer, and the substrate can be reused or used as
an evaporation source for thin film growth, which greatly reduces
material loss.

Remembering Really Fast
From U.S. Department of Energy, Office of Science, February 16, 2018:
"
Using terahertz pulses, s
cientists at the Center for
Integrated Nanotechnologies (Los Alamos National Laboratory) and the
United Kingdom have discovered colossal changes in electricity's flow at
the desired frequencies and temperature. Researchers found a colossal
magnetoresistance at terahertz frequencies at room temperature in
high-quality functional nanocomposites. The terahertz conductivity of
nanocomposites can be controlled by both an applied magnetic field and
temperature. These findings demonstrated a new approach of utilizing
optic pulses at terahertz frequencies to probe magnetoresistance, which
can revolutionize the design of future memory devices.

Copper Evaporation During Low Pressure Carburizing
From HTPro
, February/March 2018, by Trevor Jones et al. (Solar Atmospheres, Inc.)
:
"
Low pressure carburizing (LPC) in a vacuum
furnace is increasingly the preferred method for case hardening
aerospace gears, with some alloys like Ferrium C61 and C64 designed
specifically for LPC. Stringent pressure control and gas species type
both play an important role in minimizing the evaporation rate of not
only copper, but other elements susceptible to evaporation in vacuum
systems. Nitrogen at 2.5 Torr is the most economic and effective gas for
minimizing copper evaporation.

Toyota Develops New Magnet for Electric Motors Aiming to Reduce Use of Critical Rare-Earth Element
From
Toyota (Japan), February 20, 2018:
"
Toyota Motor Corporation (Toyota) announces
that it has developed the world's first neodymium-reduced,
heat-resistant magnet. Neodymium magnets are used in various types of
motors such as the high-output motors found in electrified vehicles, use
of which is expected to increase rapidly in the future. The new magnet
uses significantly less neodymium, a rare-earth element ("rare earth"),
and can be used in high-temperature conditions. The newly developed
magnet uses no terbium (Tb) or dysprosium (Dy), which are rare earths
that are also categorized as critical materials necessary for highly
heat-resistant neodymium magnets. A portion of the neodymium has been
replaced with lanthanum (La) and cerium (Ce), which are low-cost rare
earths, reducing the amount of neodymium used in the magnet.
