A new method enables researchers to analyze magnetic nanostructures with a high resolution. It was developed by researchers at Martin Luther University Halle-Wittenberg (MLU) and the Max Planck Institute of Microstructure Physics in Halle.

The new method achieves a resolution of around 70 nanometers, whereas normal light microscopes have a resolution of just 500 nanometers. This result is important for the development of new, energy-efficient storage technologies based on spin electronics. The team reports on its research in the current issue of the journal ACS Nano.

Normal optical microscopes are limited by the wavelength of light and details below around 500 nanometers cannot be resolved. The new method overcomes this limit by utilizing the anomalous Nernst effect (ANE) and a metallic nano-scale tip. ANE generates an electrical voltage in a magnetic metal that is perpendicular to the magnetization and a temperature gradient.

A team of researchers from Jilin University, NYU Abu Dhabi’s Smart Materials Lab, and the Center for Smart Engineering Materials, led by Professor of Chemistry Pance Naumov, has developed a new crystalline material that can harvest water from fog without any energy input.

The design of the novel type of smart crystals, which the researchers named Janus crystals, is inspired by desert plants and animals, which can survive in arid conditions. Desert beetles and lizards, for example, have evolved to develop surface structures that have both hydrophilic and hydrophobic areas and effectively capture moisture from the air. Water is attracted to the hydrophilic areas and droplets are accumulated and transported through the hydrophobic areas.

The findings are presented in the paper titled “Efficient Aerial Water Harvesting with Self-Sensing Dynamic Janus Crystals,” recently published in the Journal of the American Chemical Society.

The weird thermodynamics found in time crystals could be harnessed to store energy in a quantum battery-like device.

As energy from the sun reaches Earth, some solar radiation is absorbed by the atmosphere, leading to chemical reactions like the formation of ozone and the breakup of gas molecules. A new approach for modeling these reactions, developed by a team led by scientists at Penn State, may improve our understanding of the atmosphere on early Earth and help in the search for habitable conditions on planets beyond our solar system.

The researchers have reported in the journal JGR Atmospheres that using a statistical method called correlated-k can improve existing photochemical models used to understand conditions on early Earth.

The approach can help scientists better understand the atmospheric composition of early Earth and will play an important role as new observatories come online in the coming decades that can provide new data on exoplanet atmospheres, the scientists said.

Revolutionary research tool will dial up gravity to mimic natural events and help to tap future energy reserves, solve engineering puzzles.

WASHINGTON — Impulse Space has purchased three Falcon 9 launches for its Helios transfer vehicle for missions starting in 2026, including one for the Space Force.

Impulse Space announced Nov. 14 that it signed a contract with SpaceX for the Falcon 9 launches. Each launch will carry the company’s Helios transfer vehicle, a high-energy kick stage the company introduced in January to transport payloads quickly between orbits.

The first launch, planned for mid-2026, will be the first flight of Helios. The transfer vehicle will transport the company’s smaller Mira vehicle, carrying a commercial optical payload, from low Earth orbit to geostationary transfer orbit on the Victus Surgo mission for the Space Force and Defense Innovation Unit. Impulse Space received a $34.5 million contract for Victus Surgo and another mission, Victus Salo, Oct. 3. Impulse Space said the schedule and payloads for the other two Helios launches will be determined later.

China’s latest weapon, unveiled during an air show in Zhuhai, could be a game-changer during possible future conflicts with rival powers.

China is making advancements in its multiple military-related technologies that will give it an edge over its adversaries during a possible conflict in the future. During a recent giant air show in Zhuhai, Beijing unveiled multiple game-changer military technologies, including a mobile air defense weapons system.

Called FK-4000, the mobile air defense weapons system is reportedly capable of intercepting the smallest, lightest drones using its high-power microwaves (HPM).
