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.....»»
Researchers create stable hybrid laser by 3D printing micro-optics onto fibers
For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive, compact, and stable laser sources that would be useful in a vari.....»»
New salmon habitat created by melting glaciers could be threatened by mining claims, study finds
Thousands of salmon on the West Coast of North America are finding their way into new streams left behind as glaciers retreat. But a new study suggests mining companies are too keen on the newly exposed mineral deposits beneath the shrinking glaciers.....»»
Video: Permafrost thaw: A silent menace
Ice is without doubt one of the first casualties of climate change, but the effects of our warming world are not only limited to ice melting on Earth's surface. Ground that has been frozen for thousands of years, called permafrost, is thawing—addin.....»»
Research progress in pump-probe experiments at high-intensity laser facilities
The reaction kinetics of energetic materials is a key factor in determining the detonation characteristics and safety. The complexity of the reaction process and the lack of experimental means remain a notable challenge in experimental research and f.....»»
The hidden impacts of climate change on a freshwater ecosystem
From melting glaciers to rising sea levels, from raging wildfires to devastating floods, society has grown increasingly aware of the increasingly frequent climate crises. But what about its subterranean flow? A research group led by Li Dongfeng at th.....»»
Melting fire-ice: Study finds climate change can cause methane to be released from the deep ocean
New research has shown that fire-ice—frozen methane which is trapped as a solid under our oceans—is vulnerable to melting due to climate change and could be released into the sea......»»

An anomalous relativistic emission arising from the intense interaction of lasers with plasma mirrors
Interactions between intense laser pulses and plasma mirrors have been the focus of several recent physics studies due to the interesting effects they produce. Experiments have revealed that these interactions can generate a non-linear physical proce.....»»
Laser-induced hydrothermal growth for electrocatalytic applications
In the new study published in the journal International Journal of Extreme Manufacturing on 1 November 2023, researchers from the UK and China reported a novel technique based on a laser-induced hydrothermal reaction (LIHR) mechanism for the growth o.....»»
Big cities foster socioeconomic segregation: Here"s how we can fix that
We tend to think of large cities as melting pots—places where people from all sorts of backgrounds can mingle and interact. But according to new research, people in big cities tend to primarily interact with other individuals in the same socioecono.....»»
The secret life of an electromagnon: Research takes a step toward ultrafast control of magnetism with light
Scientists have revealed how lattice vibrations and spins talk to each other in a hybrid excitation known as an electromagnon. To achieve this, they used a unique combination of experiments at the X-ray free electron laser SwissFEL. Understanding thi.....»»
Scientists develop new approach for single-shot characterization of ultrashort free-electron laser pulses
Scientists at the Shanghai Advanced Research Institute (SARI) of the Chinese Academy of Sciences have proposed and validated a novel approach for single-shot characterization of ultrashort free-electron laser pulses based on self-referenced spectral.....»»

If you're thinking about buying a laser, inkjet or photo printer, you shouldn't miss the huge discounts that are available from this year's Cyber Monday deals......»»
Dynamic z-scanning for ultrafast auto-focusing in laser processing
In laser-based manufacturing, accommodating non-flat, or changing surfaces has traditionally been labor-intensive, involving complex focus mapping procedures and or ex-situ characterization. This often results in repositioning errors and extended pro.....»»
Meet the new instruments that will take advantage of SLAC"s upgraded X-ray laser
Teams at the U.S. Department of Energy's SLAC National Accelerator Laboratory recently celebrated the completion of a major upgrade to the world's first hard X-ray free-electron laser (XFEL), the Linac Coherent Light Source (LCLS) at the US Departmen.....»»
Creating vortices in a superfluid made of light
By using a special combination of laser beams as a very fast stirrer, RIKEN physicists have created multiple vortices in a quantum photonic system and tracked their evolution. This system could be used to explore exotic new physics related to the eme.....»»
Q&A: To save the planet"s glaciers, human actions still matter, says scientist
Climate change is melting glaciers around the world. Vanishing ice means less water for the millions of people relying on it and threatens the habitats of species—from bacteria to plants and fish—that live in glacier-fed ecosystems......»»
