Graphene: It is all about the toppings

Researchers at Vienna University of Technology and University of Vienna observed for the first time the individual steps of growing indium oxide on graphene using an electron microscope at atomic resolution. The combination of indium oxide with graphene is important, for example, for displays and sensors.

Porous graphene ribbons doped with nitrogen for electronics and quantum computing

Researchers led by University of Basel and University of Bern succeeded in producing the first graphene ribbons whose crystal lattice contains both periodic pores and a regular pattern of nitrogen atoms. These ribbons have semiconducting properties that make them attractive for applications in electronics and quantum computing.

For next-generation semiconductors, 2D tops 3D

Pohang University of Science & Technology researchers developed a memory device using a halide perovskite material with a 2D layered structure. The memory device maintained its memory characteristics over 140°C and could be operated at voltages lower than 1V.


Microscopic structures could improve perovskite solar cells

An international team led by the Max Planck Institute for Polymer Research found microscopic structures in perovskite crystals called ferroelastic twin domains can guide the charge transport in the solar cell. Clever alignment of these domains could make perovskite solar cells even more powerful.

Newer solar power equipment ages better than older units

Researchers assessed the performance of 411 utility-scale photovoltaic projects built within the U.S. from 2007 through 2016 and found that newer projects have degraded at a slower rate than older ones, suggesting PV technology has improved over time.

Research points to strategies for recycling of solar panels

Researchers at the National Renewable Energy Laboratory conducted the first global assessment into the most promising approaches to end-of-life management for solar photovoltaic modules. They recommend research and development to reduce recycling costs and environmental impacts while maximizing material recovery.


Machine learning reveals vulnerabilities in 3D-printed carbon-fiber composites

New York University researchers showed machine learning tools applied to a CT scan of microstructures in complex composite materials can reverse engineer the 3D-printing toolpaths that CAD file instructions use to print the piece—essentially opening a way to steal valuable trade secrets from manufacturers.


Online summer school: Electric & magnetic field-assisted processing of inorganic materials

Forschungszentrum Jülich is holding a free online summer school on electric and magnetic field-assisted processing of inorganic materials from Sept. 14–16, 2020. Register by September 1 via email to

New breakthrough in ‘spintronics’ could boost high speed data technology

Researchers led by University of Exeter experimentally demonstrated that high frequency alternating spin currents can be transmitted by, and sometimes amplified within, thin layers of antiferromagnetic NiO, a discovery which may lead to more efficient future wireless communication technology.

Ways to keep buildings cool with improved super white paints

University of California, Los Angeles researchers demonstrated ways to make super white paint that reflects as much as 98% of incoming heat from the sun by replacing titanium oxide with inexpensive and readily available ingredients such as powdered polytetrafluoroethylene (Teflon) and barite.

Scientists analyze composition of Rome’s clear glass

Scientists from the Danish National Research Foundation, Aarhus University, and the University of Münster developed a technique to distinguish between clear glass manufactured in Egypt and in the Levant during the Roman period. The technique measures hafnium isotopes in the glass, which can then be matched to sands used to make the glass.
