Researchers from Ekaterinburg, Russia, have developed and tested a new solid oxide electrolysis cell. They observed increased performance of the cell when the reducing atmosphere was enriched with carbon dioxide.
Osaka University researchers developed the first device that can detect single-electron events in a self-assembled quantum dot in real time. The device detects the single-electron tunneling events of one quantum dot as changes in the current produced by a second quantum dot in close proximity. This device allows single-electron events in quantum dots to be investigated, which is beneficial for the development of photonic devices and quantum computing.
A team including researchers from Nagoya University finds evidence of collisionless energy transfer occurring in the plasma of Earth's magnetosphere.
Osaka University-led team provides insights into the distribution of pesticides within insects using a newly developed method of insect sample preparation.
The spatial and temporal dynamics of proteins or organelles plays a crucial role in controlling various cellular processes and in development of diseases. Yet, acute control of activity at distinct locations within a cell cannot be achieved. In the journal Angewandte Chemie, scientists from Umeå University (Sweden) and the Max Planck Institute of Molecular Physiology (Germany) present a new chemo-optogenetic method that enables tunable, reversible, and rapid control of activity at multiple subcellular compartments within a living cell.
Serratia marcescens Chitinase A (SmChiA) is a molecular motor efficiently hydrolyzing recalcitrant crystalline chitin by moving on the surface processively. By using gold-nanoparticle probe, researchers revealed 1-nm stepping motion of SmChiA rectified forward by fast catalysis. X-ray crystallography and molecular dynamics simulation also revealed that motion of SmChiA is driven by the Brownian motion. The results show SmChiA is 'burnt-bridge' Brownian ratchet monorail, and give an insight to design engineered and artificial molecular motors.
Physicists from the Institute for Solid State Physics at the University of Tokyo have generated the strongest controllable magnetic field ever produced. The field was sustained for longer than any previous field of a similar strength. This research could lead to powerful investigative tools for material scientists and may have applications in fusion power generation.
Smartphones and laptops seem ubiquitous at US universities, but there is still a 'digital divide,' with some students less likely than others to have consistent access to reliable technology, according to a study co-authored by an Indiana University sociologist.
Young-Shin Jun, professor of energy, environmental & chemical engineering in the School of Engineering & Applied Science, and Quingun Li, a former doctoral student in her lab, are the first to measure the activation energy and kinetic factors of calcium carbonate's nucleation.
Since 2010, pistachio farmers from Sicily have been reporting a disease on the trees, characterised by cankers and declines, sometimes leading to the collapse of entire plants. Having surveyed 15 pistachio orchards from three provinces, as well as potted plants, an international team of researchers identified a new disease caused by a previously unknown fungus. The aetiology of the disease and the new pathogenic species are described in the open access journal MycoKeys.
