Clingy copper ions contribute to catalyst slowdown
Heavy-duty diesel trucks on the road today are equipped with aftertreatment systems that include selective catalytic reduction (SCR) technology using urea solution as a reducing agent to curtail harmful nitrogen oxide (NOx) emissions from engine exha.....»»
New research computes first step toward predicting lifespan of electric space propulsion systems
Electric space propulsion systems use energized atoms to generate thrust. The high-speed beams of ions bump against the graphite surfaces of the thruster, eroding them a little more with each hit, and are the systems' primary lifetime-limiting factor.....»»
New study highlights the impact of two new marine gases on climate models" accuracy
In addition to oxygen, nitrogen or carbon dioxide, the air we breathe contains small amounts of organic gases, such as benzene and toluene. These oxidize into small particles or aerosols that contribute to the condensation of water in the droplets th.....»»
Kuo: Apple halts work on its custom Wi-Fi chip to prioritize 3nm Apple Silicon engineering
Apple is halting the development of its own custom Wi-Fi chip in an effort to direct more attention to Apple Silicon processors. According to Ming-Chi Kuo, the “slowdown of processor upgrades” is a concern for Apple. Therefore, it wants to devot.....»»

Volcano-like rupture could have caused magnetar slowdown
On Oct. 5, 2020, the rapidly rotating corpse of a long-dead star about 30,000 light years from Earth changed speeds. In a cosmic instant, its spinning slowed. And a few days later, it abruptly started emitting radio waves......»»
Restoring land for livelihoods can have ecological benefits, study suggests
Small-scale restoration efforts that aim to help meet livelihood needs have the potential to contribute to ecological goals in the central Indian landscape, according to a new study published in Restoration Ecology......»»

WhatsApp is working on a new Mac app that uses Apple's Mac Catalyst development framework and this will let it use system resources more efficiently.WhatsApp is offering a better Mac appWhatsApp — owned by Meta — currently offers a web-based Elec.....»»
Organic chemists develop new catalyst to selectively activate carbon-hydrogen bonds
Substituted aromatics are among the most important building blocks for organic compounds such as drugs, crop-protecting agents, and many materials. The function of the molecules is determined by the spatial arrangement of the different building block.....»»
Advancing our mastery of stereoselective photoredox reactions to produce mirror-image molecules
Researchers of the Max-Planck-Institut für Kohlenforschung have expanded the molecular toolbox for efficient, targeted syntheses: To do so, they use a very special catalyst—and the energy of light. The result of their work has now been published i.....»»
"Rubble pile" asteroids nearly impossible to destroy, study suggests
Curtin University-led research into the durability and age of an ancient asteroid made of rocky rubble and dust, revealed significant findings that could contribute to potentially saving the planet if one ever hurtled toward Earth......»»
Scientists map 3D structure and electronic properties of important biological catalyst
Making atoms and electrons behave according to researchers' intentions is no small task, but scientists often get a little help from nature......»»
New method can determine how much a predatory fish eats, which can contribute to more sustainable fishing
Imagine that in the future, we know exactly how many fish we can catch without negatively impacting either the stock of predatory fish or their prey—and that we can actually regulate the amount of fish if an excess of, say, cod suddenly occurs in a.....»»
Simulations and experiments reveal unprecedented detail about water"s motion in salt water
In salt water solutions, water molecules rapidly move around salt ions at a scale of more than a trillion times a second, according to both experiments and simulations led by scientists at New York University and the Sorbonne......»»
Our bad fashion habits—and how we might change them—in numbers
The fashion industry is estimated to contribute upwards of two percent of global greenhouse gas emissions, and is on track to get even worse if there isn't major change......»»
Study: Features of prison subcultures in Canada mitigate radicalized and extremist messaging
Prison subcultures have been described as antisocial, with ties to violence and gang membership. In extreme cases, research has also suggested that prison subcultures contribute to incarcerated people joining radical groups or embracing violent extre.....»»
ABF substrates facing short-term market headwinds in 2023
A slowdown in demand for ABF substrates starting in the second half of 2022 is expected to continue in 2023, likely to turn the supply crunch seen in the past few years into a market equilibrium this year. However, ABF substrate's long-term market pr.....»»
The mechanism of cosmic magnetic fields explored in the laboratory
Plasma is matter that is so hot that the electrons are separated from atoms. The electrons float freely and the atoms become ions. This creates an ionized gas—plasma—that makes up nearly all of the visible universe. Recent research shows that mag.....»»
PCB materials suppliers expect demand recovery after 2Q23
Suppliers of copper-clad laminates (CCL), flexible CCL, and other PCB materials expect customer demand to rebound after the second quarter of 2023, according to industry sources......»»
Significant reductions in global greenhouse gas emissions still possible
About a quarter of the world's electricity currently comes from power plants fired by natural gas. These contribute significantly to global greenhouse gas emissions (amounting to 10% of energy-related emissions according to the most recent figures fr.....»»
Hack The Box raises $55 million to expand its business
