Low-level jets create winds of change for turbines

Global wind power capacity has increased more than fivefold over the past decade, leading to larger turbines, but low-level jets are one cause for concern. The effects of these strong, energetic wind flows depend on how high the wind flows are in relation to the turbines. In the ....

WASHINGTON, February 23, 2021 One of the most performed medical diagnostic tests to ascertain the health of patients is a complete blood count, which typically includes an estimate of the hemoglobin concentration. The hemoglobin level in the blood is an important biochemical parameter that can indicate a host of medical conditions including anemia, polycythemia, and pulmonary fibrosis.
In
AIP Advances, by AIP Publishing, researchers from SigTuple Technologies and the Indian Institute of Science describe a new AI-powered imaging-based tool to estimate hemoglobin levels. The setup was developed in conjunction with a microfluidic chip and an AI-powered automated microscope that was designed for deriving the total as well as differential coun ....

Helsinki, Finland Technology helps humans maintain connections, get work done, and relax after a long day. How it can best improve the lives of animals, particularly those in captivity, however, has remained an open question.
Scientists from Aalto University, in collaboration with Korkeasaari Zoo, have designed and built an on-demand video device for white-faced saki monkeys to activate as and when they like. While enrichment systems for zoo animals have been around for some time, very few offer animals the ability to choose when and how they use the device, even though choice and control are known to promote animal welfare. ....

New material is next step toward stable high-voltage long-life solid-state batteries

Credit: University of California
A team of researchers designed and manufactured a new sodium-ion conductor for solid-state sodium-ion batteries that is stable when incorporated into higher-voltage oxide cathodes. This new solid electrolyte could dramatically improve the efficiency and lifespan of this class of batteries. A proof of concept battery built with the new material lasted over 1000 cycles while retaining 89.3% of its capacity a performance unmatched by other solid-state sodium batteries to date.
Researchers detail their findings in the Feb. 23, 2021 issue of
Nature Communications.
Solid state batteries hold the promise of safer, cheaper, and longer lasting batteries. Sodium-ion chemistries are particularly promising because sodium is low-cost and abundant, as opposed to the lithium required for lithium-ion batteries, which is mined at a high environmental cost. The goal is to build batteries that can be used in large-scale grid energy storage applicat ....

Spintronics: New production method makes crystalline microstructures universally usable

Credit: AIP Applied Physics Letters
New storage and information technology requires new higher performance materials. One of these materials is yttrium iron garnet, which has special magnetic properties. Thanks to a new process, it can now be transferred to any material. Developed by physicists at Martin Luther University Halle-Wittenberg (MLU), the method could advance the production of smaller, faster and more energy-efficient components for data storage and information processing. The physicists have published their results in the journal
Applied Physics Letters .
Magnetic materials play a major role in the development of new storage and information technologies. Magnonics is an emerging field of research that studies spin waves in crystalline layers. Spin is a type of intrinsic angular momentum of a particle that generates a magnetic moment. The deflection of the spin can propagate waves in a solid body. In magnonic components, electrons would not have to move t ....
