Scientists develop an energy-efficient strategy to reversibly change ‘spin orientation’ or magnetization direction in magnetite at room temperature — ScienceDaily

Over the last few decades, conventional electronics has been rapidly reaching its technical limits in computing and information technology, calling for innovative devices that go beyond the mere manipulation of electron current. In this regard, spintronics, the study of devices that exploit the “spin” of electrons to perform functions, is one of the hottest areas in applied physics. But, measuring, altering, and, in general, working with this fundamental quantum property is no mean feat.

Current spintronic devices — for example, magnetic tunnel junctions — suffer from limitations such as high-power consumption, low operating temperatures, and severe constraints in material selection. To this end, a team of scientists at Tokyo University of Science and the National Institute for Materials Science (NIMS), Japan, has recently published a study in ACS Nano, in which they present a surprisingly simple yet efficient strategy to manipulate the magnetization angle in magnetite (Fe3O

Luminar and Intel’s Mobileye team up to develop a fleet of robo-taxis

Lidar startup Luminar today announced a partnership with Intel’s Mobileye to collaborate on self-driving car development. As part of the agreement, Luminar says it will work with Mobileye to use the former’s lidar for its robo-taxi pilot and first-generation driverless fleet in regions around the world, including Tel Aviv, Dubai, Paris, and Daegu City.

Some experts predict the pandemic will hasten adoption of autonomous transportation technologies. Despite needing disinfection, driverless cars can potentially minimize the risk of spreading disease. In partnership with Moovit, the mobility-as-a-service startup Mobileye acquired in May for $900 million, Mobileye aims to build full end-to-end ride-hailing experiences with its Luminar lidar-equipped vehicles using Moovit’s mobility platform and apps.

Mobileye, which Intel acquired for $15.3 billion in March 2017, is building two independent self-driving systems. One is based entirely on cameras, while the second incorporates radar, lidar sensors, modems, GPS, and other components. It’s this second system

Texas A&M System helps develop new COVID-19 breathalyzer kiosk

Researchers are currently working to obtain FDA emergency use authorization before beginning mass production early next year.

HOUSTON — At Texas A&M University, researchers are working on a way to get us all back to normal. 

“Most Americans don’t have COVID-19, but we’re treating ourselves like we do,” said Rob Gorham, executive director of the Secure America Institute at Texas A&M University. “The end objective is to rapidly detect and help determine folks don’t have COVID.”

Worlds Inc., the U.S. Air Force and Texas A&M teamed up to develop these breathalyzer kiosks.

“You literally breathe into the device,” said Gorham. 

You can use something as simple as a straw. There’s no contact required. The device uses artificial intelligence to analyze that breath for signs of the virus. A result is sent to your phone within seconds. The copper inlet heats itself between each use to clean and sanitize the device.

Volvo Cars “ultimate driving simulator” uses latest gaming technology to develop safer cars

Volvo Cars engineers call it “the ultimate driving simulator”, but it is not just an excuse for them to indulge their inner basement gamer. Instead, the Swedish company’s ground-breaking mixed-reality simulator is used to make new strides in safety and autonomous driving technology.

A setup with a moving driving seat, a steering wheel with haptic feedback and a crystal-clear virtual reality headset would make any serious gamer jealous, but Volvo Cars’ simulator takes this concept to the next level, making it hard to tell reality from simulation. Which is exactly the point.

Using cutting-edge technology from the leading real-time 3D development platform Unity and Finnish virtual and mixed reality experts Varjo, the simulator involves driving a real car on real roads. It combines life-like, high definition 3D graphics, an augmented reality headset, and a full-body Teslasuit that provides haptic feedback from a virtual world, while also monitoring bodily reactions.

Machine learning innovation to develop chemical library — ScienceDaily

Machine learning has been used widely in the chemical sciences for drug design and other processes.

The models that are prospectively tested for new reaction outcomes and used to enhance human understanding to interpret chemical reactivity decisions made by such models are extremely limited.

Purdue University innovators have introduced chemical reactivity flowcharts to help chemists interpret reaction outcomes using statistically robust machine learning models trained on a small number of reactions. The work is published in Organic Letters.

“Developing new and fast reactions is essential for chemical library design in drug discovery,” said Gaurav Chopra, an assistant professor of analytical and physical chemistry in Purdue’s College of Science. “We have developed a new, fast and one-pot multicomponent reaction (MCR) of N-sulfonylimines that was used as a representative case for generating training data for machine learning models, predicting reaction outcomes and testing new reactions in a blind prospective manner.

Researchers from Jena and Cambridge develop glass materials with novel combinations of properties — ScienceDaily

Linkages between organic and inorganic materials are a common phenomenon in nature, e.g., in the construction of bones and skeletal structures. They often enable combinations of properties that could not be achieved with just one type of material. In technological material development, however, these so-called hybrid materials still represent a major challenge today.

A new class of hybrid glass materials

Researchers from the Universities of Jena (Germany) and Cambridge (GB) have now succeeded in creating a new class of hybrid glass materials that combine organic and inorganic components. To do this, the scientists use special material combinations in which chemical bonds between organometallic and inorganic glasses can be generated. They included materials composed of organometallic networks — so-called metal-organic frameworks (MOFs) — which have recently been experiencing rapidly increasing research interest. This is primarily because their framework structures can be created in a targeted manner, from the length scale of

Researchers develop scalable method to help address PPE supply chain issues, help hospitals with limited resources — ScienceDaily

As the weather turns cooler and people move activities indoors, the number of new coronavirus (COVID-19) cases being reported in the United States is rising. This mirrors COVID-19 activity already seen in Europe and elsewhere across the globe.

Meanwhile, supply-chain problems are likely to cause limited supplies of filtering facepiece respirators, such as N95 masks. Yet strategies to decontaminate personal protective equipment, or PPE, remain unresolved in many hospitals with limited resources, both in the United States and abroad.

University of Delaware researchers, led by biomedical engineer Jason Gleghorn, have devised a system for decontaminating N95 masks using off-the-shelf materials available at any hardware store combined with ultraviolet type C (UV-C) lights found in shuttered research laboratories.

The UD-developed method offers comparable decontamination to more expensive methods at an affordable cost of about $50 in materials.

“We focused on frugal science — how do you decontaminate PPE in a very

Mice develop diabetes after exposure through mothers — ScienceDaily

A new UC Riverside study shows flame retardants found in nearly every American home cause mice to give birth to offspring that become diabetic.

These flame retardants, called PBDEs, have been associated with diabetes in adult humans. This study demonstrates that PBDEs cause diabetes in mice only exposed to the chemical through their mothers.

“The mice received PBDEs from their mothers while they were in the womb and as young babies through mother’s milk,” said Elena Kozlova, lead study author and UC Riverside neuroscience doctoral student. “Remarkably, in adulthood, long after the exposure to the chemicals, the female offspring developed diabetes.”

Results of the study have been published in the journal Scientific Reports.

PBDEs are common household chemicals added to furniture, upholstery, and electronics to prevent fires. They get released into the air people breathe at home, in their cars, and in airplanes because their chemical bond to surfaces
