3D printing achieves a higher degree of accuracy with an electrospray technique that uses nanoparticles and solvents. The development at the State University of New York at Binghamton essentially builds on 2D print-to-print films, electrically controlling where each nanoparticle goes in a given layer.
Shrinking graphene to a 10-nanometer scale greatly enhanced electrical, thermal conductivity and thermoelectric properties of the 2D carbon material, scientists in South Korea report. "We hope that nano-patterned 2D materials can be expected to contribute to obtaining highly efficient and flexible thermoelectric materials for the self-powered devices of wearable electronics," said Son Jeong-gon, the research team leader.

A trio of transmission grid operators in Europe have signed an agreement to jointly develop a transmission hub that could provide up to 100 million Europeans with access to renewable energy by 2050, according to TenneT B.V., Energinet and TenneT GmbH. The consortium said it would explore building one or more "Power Link Islands," a man-made land mass that could provide connections for up to 100 gigawatts of installed offshore wind capacity.
US students have partnered with peers from Ghana to collaborate and solve a real-world problem as part of a science competition run by a global nonprofit. Students from McKinley Technology High School in Washington, D.C., have worked with their teammates from Winneba Senior High School in Ghana to address water issues that affect the world.
The Netherlands Aerospace Center is supporting a plan to consider circular airplane runways at different airports. Circular runways could reduce the amount of fuel planes burn on takeoff or landings, since they would not have to fight against cross winds, according to Dutch scientist Henk Hesselink, who conceived the idea.
Companies are under pressure to deliver products to market faster. Viewers will learn about a new paradigm in rapid prototyping and 3D printing that doesn’t compromise the needs of designers and engineers while enabling more accurate, detailed and repeatable prototypes at a lower cost.
MIT Nuclear Reactor Laboratory scientists say the existing facility could be used to test a one-megawatt molten salt demonstration reactor without the need to build a complete prototype. If approved by the Nuclear Regulatory Commission, this plan could cut prototype construction time in half and reduce costs by hundreds of millions of dollars.
A flexible glass has been developed by Brigham Young University researchers to allow lab-on-a-chip medical devices to trap and analyze samples for diagnostic purposes at a nanoscale level. The team, which reported its findings in the journal Applied Physical Letters, said the glass will cut the time to run diagnostic tests and make sample modification unnecessary for analysis, allowing test results to be delivered "on the spot."
Organizational learning at scale can be tackled strategically in several ways, starting with the idea of thinking about desired outcomes, writes Elizabeth Doty. Feedback is critical, whether in its timeliness or how it is sent to the people who need to be acting on it.
