Laser melting: Fewer unknowns in the laser nanosynthesis of composites
Composite particles with submicron sizes can be produced by irradiating a suspension of nanoparticles with a laser beam. Violent physical and chemical processes take place during irradiation, many of which have been poorly understood to date. Recentl.....»»
Gullies on Mars could have been formed by recent periods of liquid meltwater, study suggests
A study led by Brown University researchers offers new insights into how water from melting ice could have played a recent role in the formation of ravine-like channels that cut down the sides of impact craters on Mars......»»

In a new study published in Light: Science & Applications , a team of scientists led by Asst. Prof. Abdullah Demir from UNAM-Institute of Materials Science and Nanotechnology, Bilkent University, has successfully developed a novel electrically pumped.....»»
Researchers report on a new technique for cooling membranes with lasers
Using a new technique, researchers at the University of Basel have succeeded in cooling a small membrane down to temperatures close to absolute zero using only laser light. Such extremely cooled membranes could, for instance, find applications in hig.....»»
AlixPartners outlook warns of Chinese EV competition, "ICE melting"
Pent-up demand may temporarily buoy demand, but the ICE age is ending, AlixPartners predicts. EVs are in, and Chinese brands are ready to compete for market share......»»
A new mathematical "blueprint" is accelerating fusion device development
Developing commercial fusion energy requires scientists to understand sustained processes that have never before existed on Earth. But with so many unknowns, how do we make sure we're designing a device that can successfully harness fusion power?.....»»

Team lays groundwork for future ultra-precise timing links to geosynchronous satellites
Last year, scientists drove up Mauna Loa volcano on Hawai'i, aimed a laser at a reflector positioned on Haleakala peak on Maui, and beamed rapid pulses of laser light through 150 kilometers of turbulent air. While the pulses were exceedingly faint, t.....»»
Himalayan glaciers could lose 80% of their volume if global warming isn"t controlled, study finds
Glaciers are melting at unprecedented rates across the Hindu Kush Himalayan mountain ranges and could lose up to 80% of their volume this century if greenhouse gas emissions aren't sharply reduced, according to a report......»»
Trillionths of a second: Photon pairs compress an electron beam into short pulses
Physicists at the University of Konstanz have generated one of the shortest signals ever produced by humans: Using paired laser pulses, they succeeded in compressing a series of electron pulses to a numerically analyzed duration of only 0.00000000000.....»»
Swiss vote on net-zero climate law
The Swiss, feeling the impact of global warming on their rapidly melting glaciers, were voting on Sunday on a new climate bill aimed at steering the country towards carbon neutrality by 2050......»»
Amid melting glaciers, Swiss vote on new climate law
The Swiss, feeling the impact of global warming on their rapidly melting glaciers, were voting on Sunday on a new climate bill aimed at steering the country towards carbon neutrality......»»
Slowing deep Southern Ocean current may be linked to natural climate cycle—but melting Antarctic ice is still a concern
Our new research in the Antarctic suggests that the vital layer of cold water on the sea bed, which circulates the globe and influences the ocean's ability to continue absorbing much of the rise in atmospheric heat and greenhouse gas emissions, is he.....»»
Overcoming the trade-off between sub-nanometer size and high metal loading in meta cluster catalysts
Recognizing the ultrafast laser-to-thermal conversion capacity and the impermeable, flexible features of graphene Dr. Ye-Chuang Han and Prof. Zhong-Qun Tian conceived the idea of using the material as the diffusion-constrained nanoreactor for high-te.....»»

Amid melting glaciers, Swiss to vote on new climate law
The Swiss, feeling the impact of global warming on their rapidly melting glaciers, are expected Sunday to approve a new climate bill aimed at swiftly steering the country towards carbon neutrality......»»
Sonodynamic immunotherapy proves effective in pancreatic cancer treatment
Ultrasound is a promising technique for treating cancer. Unlike laser light, used in photodynamic cancer therapy, ultrasound waves can reach deep into tissue—up to 12 cm—to treat deep tumors without damaging healthy cells. A team of researchers r.....»»
NASA laser communications terminal delivered for Artemis II moon mission
The laser communications system for NASA's Artemis II mission arrived at NASA's Kennedy Space Center in Florida for integration with the Orion spacecraft, which will carry astronauts around the Moon for the first time since the Apollo missions......»»
Using high-tech laser gear, UN-backed team scans Ukraine historical sites to preserve them amid war
Under the plaintive painted eyes of the holy, a volunteer team of two United Nations-backed engineers watched as a whirling laser took a million measurements a second inside Kyiv's All Saints Church......»»
Study describes the melting of gold nanoparticles in gold-bearing fluids in the Earth"s crust
