A research team led by professor YU Shuhong at the University of Science and Technology of China (USTC) has reported a new class of heteronanostructures they term axial superlattice nanowires (ASLNWs), which allow large lattice-mismatch tolerance and thus vast material combinations. The research article entitled "One-Dimensional Superlattice Heterostructure Library" was published in Journal of the American Chemical Society on May 12th.
Researchers from Tokyo Medical and Dental University (TMDU) have demonstrated that delivering oxygen via the rectum as a gas or in an oxygen-rich liquid can support oxygen provision to organs and tissues during respiratory failure. Such "enteral ventilation" increased oxygenation, improved behavior and prolonged survival in experimental mouse and pig models of respiratory failure. Further research may allow its clinical application in human patients as a less invasive alternative to ventilators and artificial lungs.
The international scientific community agrees that the latest findings of an FAU research team will revolutionise the entire chemistry of magnesium. The research team have discovered magnesium, which usually has a double positive charge in chemical compounds, in the elemental zero-oxidation state. They have published their ground-breaking findings in the journal Nature.
Low-dimensional materials, such as 1D monoatomic chains, exhibit exotic properties that could find interesting applications. However, single-atom bonds and their mechanical characteristics are difficult to study. In a recent study, scientists from JAIST, Japan, showcase a novel method to simultaneously image monoatomic platinum chains with a transmission electron microscope while measuring their bond strength and conductance during mechanical stretching. This technique will help answer many questions in the fields of nanomechanics and surface science.
High-temperature and high-pressure experiments involving a diamond anvil and chemicals to simulate the core of the young Earth demonstrate for the first time that hydrogen can bond strongly with iron in extreme conditions. This explains the presence of significant amounts of hydrogen in the Earth's core that arrived as water from bombardments billions of years ago.
An international research team analyzed a database of more than 1000 supernova explosions and found that models for the expansion of the Universe best match the data when a new time dependent variation is introduced. If proven correct with future, higher-quality data from the Subaru Telescope and other observatories, these results could indicate still unknown physics working on the cosmic scale.
Kakshine is an entirely new DNA fluorescent imaging probe with a wide range of capabilities that make it ideal for a range of imaging applications, including cutting edge two-photon excitement imaging and super high-resolution STED imaging. Its ability to use low phototoxicity visible light makes it ideal for in vitro and in vivo applications, and it is expected to find use in a variety of medical and life science contexts.
Some nonpathogenic microorganisms can stimulate plant immune responses without damaging the plants, which allows them to act like plant vaccines, but screening microorganisms for such properties has traditionally been time-consuming and expensive. Now, a team of scientists from Tokyo University of Science has developed a screening method based on cultured plant cells that makes such testing easier. This may lead to microorganism-based crop protection methods that reduce the need for chemical pesticides.
Osaka University researchers employed machine learning to remove the noise from experimental data without the need for "clean" examples. As a result, the team was better able to monitor the motion of spheres through tiny nanopores. This work may lead to advances in the fast detection of even very small concentrations of pathogens in patient samples.
What The Study Did: Researchers analyzed changes in filled prescriptions for naloxone (medication to reverse opioid overdoses) during the COVID-19 pandemic in the United States and compared them with changes in opioid prescriptions and overall prescriptions.
