Nitrogen and argon plasma boosts performance of carbon-based supercapacitor electrodes

Scientists from Skoltech, the Institute of Nanotechnology of Microelectronics, RAS, and other research centers have refined the understanding of how plasma treatment of carbon-based electrodes affects the key characteristics of supercapacitors. These are energy storage devices that complement batteries in electric cars, trains, port cranes, and elsewhere. As scientists investigate the effects of various electrode modifications on capacitance, the toolkit for enhancing supercapacitor performance will expand and these devices will store more energy and find more applications. The findings are reported in Electrochimica Acta. "Our team is investigating ways to improve the performance of devices known as supercapacitors by tinkering with the carbon-based material used in their electrodes," the principal investigator of the study, Assistant Professor Stanislav Evlashin of Skoltech Materials, commented.

Large-scale plasma etching technology for mass production of next-generation 2D semiconductors

A large-scale (4-inch), highly uniform, and defect-free plasma etching technology, which will likely become the foundation of the industrial supply of molybdenum disulfide (MoS2), a next-generation two-dimensional (2D) semiconductor, has been developed. The joint research team led by Hyeong-U Kim, Senior Researcher of the Department of Plasma Engineering at the Korea Institute of Machinery and Materials (KIMM) and Professor Taesung Kim of Sungkyunkwan University, announced that the team has succeeded in developing the "large-scale (4-inch) atomic layer etching technology for MoS2, a next-generation semiconductor, using plasma-based reactive ion etcher (RIE) equipment." This research, in which senior researcher Muyoung Kim and post-doctoral researcher Changmin Kim of KIMM participated as co-first authors, has been published as the cover article of the February 2023 edition of Chemistry of Materials. As the line width of conventional silicon-based semiconductors decreases gradually, it is necessary to control the manufacturing process on an atomic level.

Tracking thermodynamic fundamentals

Physicists determine the barely-measurable property entropy for the first time in complex plasmas

Since the end of the 19th century, physicists have known that the transfer of energy from one body to another is associated with entropy. It quickly became clear that this quantity is of fundamental importance, and so began its triumphant rise as a useful theoretical quantity in physics, chemistry and engineering. However, it is often very difficult to measure. Professor Dietmar Block and Frank Wieben of Kiel University (CAU) have now succeeded in measuring entropy in complex plasmas, as they reported recently in the scientific journal Physical Review Letters. In a system of charged microparticles within this ionized gas, the researchers were able to measure all positions and velocities of the particles simultaneously. In this way, they were able to determine the entropy, as it was already described theoretically by the physicist Ludwig Boltzmann around 1880.

Surprising thermodynamic equilibrium in plasma

"With our experiments, we were able to prove that in the important model system of complex plasma, the thermodynamic fundamentals are fullfilled. What is surprising is that this applies to microparticles in a plasma, which is far away from thermodynamic equilibrium," explains PhD student Frank Wieben. In his experiments, he is able to adjust the thermal motion of the microparticles by means of a laser beam. Using video microscopy, he can observe the dynamic behaviour of the particles in real time, and determine the entropy from the information collected.

Plasmas – New Debut E.P. Released

PLASMAS – have released their radiant debut EP ‘A Summer’s Day Can Break Your Heart’. Produced by Guy Galactic, ‘A Summer’s Day Can Break Your Heart’ plays out like a scrapbook of postcards or polaroid pictures from a handful of languorous and lucid summer days — the feelings, the friends, the love and the loss all captured with a gleaming sense of realism. As frontman Ross…
