Materials in Focus
Two new methods reported for growing MoS2 on a large scale
|
|
Two new methods can produce the two-dimensional semiconductor molybdenum disulfide over an area a few centimeters wide. Large-scale syntheses of uniform MoS2 films could make it easier to build electronic and energy storage devices using the material.

3D printed supercapacitor electrodes use graphene aerogel ink
|
|
A new printable composite ink, based on graphene oxide and graphene nanoplatelets, has been developed for the fabrication of 3D-printed graphene aerogel electrodes with designed macro-architectures. A supercapacitor produced using these electrodes demonstrated outstanding energy and power density. The flexibility of the technique will allow for printing of electrodes in a wide range of geometries and architectures, opening new horizons for portable and wearable electronics and microelectronics.

Heteroepitaxial nickel-alloy thin films grown on diamond
|
|
A team of researchers in Moscow have taken a significant step toward diamond-based electronics—which are useful for high-temperature, high-power microwave electronics—by “flipping” the task of growing diamond on metal to heteroepitaxial layers of metals on a diamond.

Thermoelectric power of texture revealed in SnSe
|
|
Since 2014 the thermoelectric community has turned its attention to tin selenide (SnSe) for thermoelectricity. Doping and texturing have been exploited to improve the performance of polycrystalline SnSe, but the early results suffer from some uncertainty and a ZT > 1 has not been reported so far. Now a research team reports further success with hot-pressed SnSe ingots.

Bio Focus: Soft microrobots propelled by structured light
|
|
Miniature robots or microbots now have a new way to move—using only light. A group of researchers, led by Peer Fischer from the Max Planck Institute for Intelligent Systems in Germany, explains how a soft microbot can be made to swim in a viscous medium just using patterned light.

Single chip integrates transistors and photonic components
|
|
Each new year brings with it new cell phones and computers that out perform their predecessors. The regular and continuing improvement in computing power is one of the great successes of modern engineering; however, as consumers become more dependent on their devices, they increasingly demand better battery life. Now scientists may have created one possible solution to this problem by incorporating next-generation photonic materials into traditional circuits, promising computers that are capable of running more calculations on less energy.

Research Highlights: Perovskite-based solar cells
|
|
Many scientists believe that metal-halide perovskite solar cells will first see the light of day commercially in tandem form, stacked above silicon cells. This promises to boost commercial silicon module efficiency from about 20% to over 30%. But the necessary energy bandgap to realize such high-efficiency tandem cells has only been found in unstable perovskites.

People in Focus
Industry Focus
Airplanes are getting lighter thanks to 3D-printed parts
Metal 3D printing, which has been around for nearly two decades, is finally coming into its own as a genuine mass manufacturing technology: sales of machines that print metal objects have risen rapidly as manufacturers, especially in the aerospace industry, gear up for commercial production of additively made parts they’ve been developing for years.
Wacker opens polysilicon plant
Wacker Chemie is starting up a $2.5 billion plant in Charleston, Tenn., that will make polysilicon for the solar panel industry. The German firm is opening the facility in a market that has bottomed out but is still struggling to turn a profit.
Solar energy becomes mainstream as capacity grows 10-fold within seven years
“By the end of 2020, the amount of installed solar capacity will be 300 percent higher than today,” Dan Whitten, vice president of communications at the Solar Energy Industries Association, said. The greatest problem that the solar industry has faced has been the cost of producing energy from solar panels.
The search for a better battery
Despite the appearance of rapid technological advances, the specter of stagnation looms over the world’s innovators. Low-hanging fruit is nowhere to be seen in fields as crucial as digital electronics, biomedical devices, or space technology. Nothing illustrates the looming problem of stagnation more dramatically than the quest for a superbattery.
Policy Focus
NATO’s science program funds materials research
When materials scientists seek research funding, NATO does not immediately come to mind. Yet NATO has an annual budget of €12.5 million for civil science through its Science for Peace and Security Program. Through this program, it has funded several materials-focused projects that fall under the auspices of its strategic goals and key priorities.
Same bottom line hides sharp disagreement in US Congress over energy research
Legislators in both houses of Congress agree that science at the Department of Energy (DOE) should get a slight boost—0.9%—next year. But how they get to that number is quite another story.

OF INTEREST TO THE MATERIALS COMMUNITY
New documentary inspires collaborative action for peace in Congo
The documentary Merci Congo explores the stories of individual activists, including Carolyn Duran, Intel’s Director for Global Supply Management who visited 91 smelters in 21 countries to ensure the company's processors are made from conflict-free minerals throughout the supply chain.
Finalists’ superheroes from the Generation Nano: Small Science, Superhero competition
Contestants from high school provided written entries explaining the superhero and nanotechnology-driven gear, with particular emphasis on the research behind the nanotechnology, and a one page comic strip introducing the superhero. The challenge is sponsored by the US National Science Foundation with the National Nanotechnology Initiative.

The formation and growth of twins result in substantial evolution of microstructures and properties in a variety of metallic materials. The articles in this issue of MRS Bulletin overview the synthesis and mechanical behavior of nanotwinned metallic materials as well as plasticity dominated by mechanical twinning. The cover shows a transmission electron microscope micrograph of sputter-deposited epitaxial nanotwinned Ag in a cross-sectional view examined from the [01] zone axis. The image reveals high-density nanoscale growth twins with coherent twin boundaries normal to the growth direction. The average twin spacing is ~9 nm, and the average columnar domain size is ~120 nm.
