‘Wrapping’ anodes in 3D carbon nanosheets: The next big thing in li-ion battery technology

Study finds that anchoring manganese selenide nanoparticles, an anode material, in 3D carbon nanosheets prevents their expansion in lithium-ion batteries

Global approach is needed on battery regulation

New European Union regulations on batteries could offer a huge boost to the global decarbonisation mission – but only if it leverages its political and economic weight to ensure a fairer global marketplace. According to a team of scientists and…

Solar cells: Layer of three crystals produces a thousand times more power

The photovoltaic effect of ferroelectric crystals can be increased by a factor of 1,000 if three different materials are arranged periodically in a lattice. This has been revealed in a study by researchers at Martin Luther University Halle-Wittenberg (MLU). They…

An automated flight control system for drone swarms has been developed

“The project’s main objective is to integrate a certain degree of automation, so that an operator can control a small fleet of up to 10 drones from a single ground station,” says Luis E. Moreno, LABYRINTH’s coordinator and researcher at…

Bonding’s next top model — Projecting bond properties with machine learning

Tokyo, Japan – Designing materials that have the necessary properties to fulfill specific functions is a challenge faced by researchers working in areas from catalysis to solar cells. To speed up development processes, modeling approaches can be used to predict…

NASA returns Hubble Space Telescope to science operations

NASA has returned the science instruments on the Hubble Space Telescope to operational status, and the collection of science data will now resume. This will be the first science data collected since the payload computer experienced a problem on June…

Introduction to 6G vision and technology

The book starts with a general vision of 6G technology, which includes the motivation that drives 6G research, the international organizations working on 6G standardization and recent progress in 6G research. It also provides details about the millimetre wave and…

Solar radio signals could be used to monitor melting ice sheets

The sun provides a daunting source of electromagnetic disarray – chaotic, random energy emitted by the massive ball of gas arrives to Earth in a wide spectrum of radio frequencies. But in that randomness, Stanford researchers have discovered the makings…

Unlocking radiation-free quantum technology with graphene

“Heavy fermions” are an appealing theoretical way to produce quantum entangled phenomena, but until recently have been observed mostly in dangerously radioactive compounds. A new paper shows it is possible to make them in subtly modified graphene

DGIST launched ‘Institute of Next-generation Semiconductor convergence Technology (INST)’

DGIST opened INST to support the creation and further commercialization of next-generation semiconductor convergence technologies. President Young Kuk, DGIST, as well as other prominent administrators and academic members, attended the opening ceremony. Since 2011, DGIST has established the “Seven Core…

Beyond 5G: Wireless communications may get a boost from ultra-short collimating metalens

Screens may be larger on smartphones now, but nearly every other component is designed to be thinner, flatter and tinier than ever before. The engineering requires a shift from shapely, and bulky lenses to the development of miniaturized, two-dimensional metalenses.…

Plant patch enables continuous monitoring for crop diseases

Researchers from North Carolina State University have developed a patch that plants can “wear” to monitor continuously for plant diseases or other stresses, such as crop damage or extreme heat. “We’ve created a wearable sensor that monitors plant stress and…

Wildfire detection takes flight

Networks of ground-based sensors paired with airborne drones could give firefighters a critical edge when battling wildfires, KAUST researchers have found. The sensor/unmanned aerial vehicle (UAV) network could significantly shorten the time taken to detect a wildfire, giving firefighters a…

Engineer’s graphene additive manufacturing research makes journal’s cover story

MANHATTAN, KANSAS — Research led by Kansas State University’s Suprem Das, assistant professor of industrial and manufacturing systems engineering, in collaboration with Christopher Sorensen, university distinguished professor of physics, shows potential ways to manufacture graphene-based nano-inks for additive manufacturing of…

Cold weather cost New England electric customers nearly $1.8 billion in one month; A new study suggests ways to mitigate fuel shortages

In New England, constraints in the supply of natural gas have led to nearly a quarter of all unscheduled power plant outages. In a new study, researchers used data from power plant failures in the 2010s to develop a supply…

Machine learning for solar energy is supercomputer kryptonite

Scientists have found a way to predict the band gap of photovoltaics materials in milliseconds with a conventional PC, potentially leaving the world’s most powerful and expensive processing machines gathering dust

AI system-on-chip runs on solar power

AI is used in an array of extremely useful applications, such as predicting a machine’s lifetime through its vibrations, monitoring the cardiac activity of patients and incorporating facial recognition capabilities into video surveillance systems. The downside is that AI-based technology…
