🗞 TECHNOLOGY NEWS💻🔧🖥:
RESEARCHERS IDENTIFY A STRATEGY TO ACHIEVE LARGE TRANSPORT GAP MODULATION IN GRAPHENE
Over the past decade or so, the semimetal graphene has attracted substantial interest among electronics engineers due to its many advantageous qualities and characteristics. In fact, its high electron mobility, flexibility and stability make it particularly desirable for the development of next-generation electronics.
BIOROBOTICS LAB BUILDS SUBMERSIBLE ROBOT SNAKE
Carnegie Mellon University’s acclaimed snake-like robot can now slither its way underwater, allowing the modular robotics platform to inspect ships, submarines and infrastructure for damage.
MEMBRANE DESIGN PREVENTS CROSSOVER IN POLYSULFIDE REDOX FLOW BATTERIES
Two researchers at the Chinese University of Hong Kong have developed a new membrane design that prevents crossover in polysulfide redox flow batteries. In their paper published in the journal Nature Energy, Zhejun Li and Yi-Chun Lu describe their work with the new membrane design. Wei Wang with Northwest National Laboratory has published a News & Views piece in the same journal issue describing problems with polysulfide redox flow batteries and the work by Li and Lu to overcome them.
🗞 PHYSICS NEWS⚙♨:
WATER AND QUANTUM MAGNETS SHARE CRITICAL PHYSICS
In physics, things exist in phases, such as solid, liquid and gas states. When something crosses from one phase to another, we talk about a phase transition—like water boiling into steam, turning from liquid to gas.
FAST-SPINNING BLACK HOLES NARROW THE SEARCH FOR DARK MATTER PARTICLES
Ultralight bosons are hypothetical particles whose mass is predicted to be less than a billionth the mass of an electron. They interact relatively little with their surroundings and have thus far eluded searches to confirm their existence. If they exist, ultralight bosons such as axions would likely be a form of dark matter, the mysterious, invisible stuff that makes up 85 percent of the matter in the universe.
LITTLE SWIRLING MYSTERIES: NEW RESEARCH UNCOVERS DYNAMICS OF ULTRASMALL, ULTRAFAST GROUPS OF ATOMS
Our high-speed, high-bandwidth world constantly requires new ways to process and store information. Semiconductors and magnetic materials have made up the bulk of data storage devices for decades. In recent years, however, researchers and engineers have turned to ferroelectric materials, a type of crystal that can be manipulated with electricity.
🗞 EARTH NEWS🌏:
INDIGENOUS LAND-USE REDUCED CATASTROPHIC WILDFIRES ON THE FISH LAKE PLATEAU
If you were to visit the Great Basin and Colorado Plateau a thousand years ago, you’d find conditions remarkably familiar to the present. The climate was warm, but drier than today. There were large populations of Indigenous people known as the Fremont, a who hunted and grew crops in the area. With similar climate and moderate human activity, you might expect to see the types of wildfires that are now common to the American West: infrequent, gigantic and devastating. But you’d be wrong.
TO IMPROVE CLIMATE MODELS, AN INTERNATIONAL TEAM TURNS TO ARCHAEOLOGICAL DATA
Climate modeling is future facing, its general intent to hypothesize what our planet might look like at some later date. Because the Earth’s vegetation influences climate, climate models frequently include vegetation reconstructions and are often validated by comparisons to the past. Yet such models tend to get oversimplified, glossing over or omitting how people affected the land and its cover.
CLIMATE CHANGE MAKES INDIAN MONSOON STRONGER, MORE ERRATIC: STUDY
Climate change is making India’s monsoon stronger and more chaotic, scientists said Wednesday, warning of potential severe consequences for food, farming and the economy affecting nearly a fifth of the world’s population.
🗞 ASTRONOMY & SPACE NEWS🌪🎇:
TELESCOPES UNITE IN UNPRECEDENTED OBSERVATIONS OF FAMOUS BLACK HOLE
In April 2019, scientists released the first image of a black hole in galaxy M87 using the Event Horizon Telescope (EHT). However, that remarkable achievement was just the beginning of the science story to be told.
MOCK CREW STRAPS INTO SPACE CAPSULE, EXITS BEFORE LIFTOFF
Jeff Bezos’ Blue Origin company strapped two employees into a fueled rocketship for practice, but pulled them out shortly before sending the capsule to the edge of space Wednesday with only a test dummy.
POPPING PILLS IN SPACE: HELPING ASTRONAUTS MANAGE PAIN OR SICKNESS ON CREWED MISSIONS
And you think you’ve had a bad head cold.
🗞 NANOTECHNOLOGY NEWS⛄☃:
FINALLY, 3D-PRINTED GRAPHENE AEROGELS FOR WATER TREATMENT
Graphene excels at removing contaminants from water, but it’s not yet a commercially viable use of the wonder material.
LONG-ACTING INJECTABLE MEDICINE AS POTENTIAL ROUTE TO COVID-19 THERAPY
Researchers from the University of Liverpool have shown the potential of repurposing an existing and cheap drug into a long-acting injectable therapy that could be used to treat COVID-19.
INTERLAYER EXCITON FORMATION, RELAXATION, AND TRANSPORT IN TMDS VAN DER WAALS HETEROSTRUCTURES
Interlayer excitons in transition metal dichalcogenides (TMDs) van der Waals (vdW) heterostructures exhibit fascinating physics and hold great promise for developing excitonic devices. Scientists in China present a systematical and comprehensive overview of the interlayer exciton formation, relaxation, transport, and potential applications of TMDs vdW heterostructures, in order to provide valuable guidance for new researchers in this field as well as to present the most important issues present in the field for future deep studies.
