An international team of scientists led by researchers from the Laboratory of Nanomaterials at the Skoltech Center for Photonics and Quantum Materials (CPQM) have rationally designed a novel p-type flexible transparent conductor using single-walled carbon nanotubes. This opens new avenues for its applications in next generation opto-electronics and energy technologies. The results of the study were published in the prestigious international journal Nano Energy.

Rice University engineers print 3D blocks based on theoretical tubulanes and find they're nearly as hard as diamond.

To seamlessly integrate electronics with the natural world, materials are needed that are both stretchable and degradable -- for example, flexible medical devices that conform to the surfaces of internal organs, but that dissolve and disappear when no longer needed. However, introducing these properties to electronics has been challenging. Now, researchers reporting in ACS Central Science have developed stretchable, degradable semiconductors that could someday find applications in health and environmental monitoring.

Physicists from the German research center Helmholtz-Zentrum Dresden-Rossendorf (HZDR) are working to produce engineered magnetic nanostructures and to tailor material properties at the nanoscale. The scientists use a special microscope at the HZDR Ion Beam Center to achieve this goal. This microscope's ultrathin ion beam is capable of producing stable, periodically arranged nanomagnets in a sample material. The device can also be used to optimize the magnetic properties of carbon nanotubes.

An international research collaboration from Poland, the UK and Russia has created a two-dimensional system -- a thin optical cavity filled with liquid crystal -- in which they trapped photons. As the properties of the cavity were modified by an external voltage, the photons behaved like massive quasiparticles endowed with a magnetic moment, called 'spin', under the influence of an artificial magnetic field. The research has been published in Science on Friday, Nov. 8, 2019.

An Australian study revealing new spin textures in pyrite could unlock these materials' potential in future spintronics devices. The study of pyrite-type materials provides new insights and opportunities for selective spin control in topological spintronics devices.

Researchers at Linköping University and RISE, Campus Norrköping, have shown for the first time that it is possible to print complete integrated circuits with more than 100 organic electrochemical transistors. The result has been published in Nature Communications.

Researchers at Kanazawa University controlled the magnetic properties of a metal layer through the electrical polarization of a neighboring metal oxide layer. Computational simulations and experimental measurements revealed that the magnetism of a cobalt-platinum alloying layer strongly depended on the polarization direction of an overlying magnesium zinc oxide layer. The concept of magnetic property control using electrical polarization shows potential to advance the development of nonvolatile magnetic memory.
