Think about your favorite t-shirt, the one you've worn a hundred times, and all the abuse you've put it through. You've washed it more times than you can remember, spilled on it, stretched it, crumbled it up, maybe even singed it leaning over the stove once.
We put our clothes through a lot and if the smart textiles of the future are going to survive all that we throw at them, their components are going to need to be resilient.
As many Americans struggle to pay their bills, keeping up with mortgage payments can be daunting with the risk of losing one's home. The challenges to retain a home are stratified along racial differences. Black homeowners are twice as likely to lose their homes and transition back to renting than white homeowners, according to a recent Dartmouth-led study published in Demography .
Arizona State University's Scott Sayres and his team have recently published an ultrafast laser study on uncharged iron oxide clusters, which could ultimately lead to the development of new and less-expensive industrial catalysts. It might also contribute to a better understanding of the universe since iron oxides are observed in the emission spectra of stars.
Sayres is an assistant professor in ASU's School of Molecular Sciences and a faculty member in the Biodesign Institute's Center for Applied Structural Discovery.
COLUMBUS, Ohio - Service requests to city non-emergency telephone lines can help identify "hotspots" for opioid use and overdoses, a study in Columbus found.
Researchers found that calls to the 311 line - used in many cities across the United States to report non-emergency issues - tracked closely to places and times in Columbus in which opioid overdose events were on the rise.
Findings showed that calls about code violations, public health and street lighting were the best indicators of opioid use in Columbus communities.
Climate change is causing hurricanes that make landfall to take more time to weaken, reports a study published 11th November 2020 in leading journal, Nature.
The researchers showed that hurricanes that develop over warmer oceans carry more moisture and therefore stay stronger for longer after hitting land. This means that in the future, as the world continues to warm, hurricanes are more likely to reach communities farther inland and be more destructive.
Camels have evolved a seemingly counterintuitive approach to keeping cool while conserving water in a scorching desert environment: They have a thick coat of insulating fur. Applying essentially the same approach, researchers at MIT have now developed a system that could help keep things like pharmaceuticals or fresh produce cool in hot environments, without the need for a power supply.
COLUMBUS, Ohio - A new study by led by researchers at The Ohio State University Wexner Medical Center and The Ohio State University College of Medicine finds that exercising your brain with "neurobics" before surgery can help prevent post-surgery delirium.
An international team of researchers with an effort called the Zoonomia Project has analyzed and compared the whole genomes of more than 80 percent of all mammalian families, spanning almost 110 million years of evolution. The genomic dataset, published today in Nature, includes genomes from more than 120 species that were not previously sequenced, and captures mammalian diversity at an unprecedented scale.
Six days after a prone and restrained George Floyd died under the knee of a Minneapolis police officer, National Security Advisor Robert O'Brien dismissed charges that racism is rampant among police by arguing that "a few bad apples" are giving police "a terrible name."
Developing new materials takes a lot of time, money and effort. Recently, a POSTECH research team has taken a step closer to creating new materials by applying AI to develop high-entropy alloys (HEAs) which are coined as "alloy of alloys."
With the aging of the world's population, there is a growing interest in elucidating the factors that support wellbeing in old age. Longitudinal life course epidemiological research is required to provide a continuous view from birth to old age and clarify what factors in the early life stages (e.g., adolescence) enhance wellbeing in old age.
In jargon, they are called "bad metals", but they are not really so bad. As a matter of fact, they are the best superconductors because they are able to conduct current with the highest efficiency and without resistance up to high temperatures. This has been seen experimentally. Yet their behaviour remains a mystery.
Oxygen evolution reaction (OER) is a key process for many energy devices such as electrolyzers and rechargeable metal-air batteries. Tremendous studies have been devoted to obtaining cost-effective, efficient and durable OER catalysts. Among them, nickel-based materials are considered to be promising candidates for OER in alkaline media. However, their performances are still below the expectation and the active sites are often controversial.
The Japanese research team elucidated the microscopic mechanism in which amorphous silica(1) becomes negatively charged as a vibrational energy harvester(2), which is anticipated to achieve self-power generation without charging, as it is needed for IoT that is garnering attention in recent years with its "trillion sensors" that create a large-scale network of sensors. Unlike wind power and solar power generation, vibrational power generation, which utilizes natural vibration for power generation, is not affected by weather.
The water electrolysis is an electrochemical way for production of hydrogen, which is considered as one of the future energy carrier molecules. Therefore, looking at numerous advantages of proton exchange membrane electrolysis compared to the classical alkaline variant, it's efficiency and applicability on the large scale is of huge importance nowadays. However, the slow kinetics of the anode oxygen evolution reaction (OER) limits the overall electrolysis process and requires an active and stable electrocatalyst.
