Chemists unravel reaction mechanism for clean energy catalyst
Hydrogen, the simplest element on Earth, is a clean fuel that could revolutionize the energy industry. Accessing hydrogen, however, is not a simple or clean process at all. Pure hydrogen is extremely rare in nature, and practical methods to produce i.....»»
Silicon Catalyst announces "Silicon Startups Contest" in partnership with Arm
On May 10, 2023, Silicon Catalyst, the world's only incubator focused exclusively on accelerating semiconductor solutions, announced a "Silicon Startups Contest" in partnership with Arm. The contest is organized and administered by Silicon Catalyst a.....»»
Modeling electron dynamics in real time
Making the dynamics of an excited molecule visible is only possible using computationally intensive simulations. Recently, a research team led by Sandra Luber from the University of Zurich has developed a method that speeds up these complex simulatio.....»»
Modeling study shows plastic can drift far away from its starting point as it sinks into the sea
Discarded or drifting in the ocean, plastic debris can accumulate on the water's surface, forming floating islands of garbage. Although it's harder to spot, researchers suspect a significant amount also sinks. In a new study in Environmental Science.....»»
CACI collaborates with Torchlight to provide secure access to dark web for SOF customers
CACI announced a strategic partnership to provide the DarkPursuit capability within the Torchlight Catalyst platform. This partnership will provide Torchlight customers, mainly Special Operations Forces (SOF), with safe and secure access to browse th.....»»
Study of Uranus" large moons shows four may hold water
Re-analysis of data from NASA's Voyager spacecraft, along with new computer modeling, has led NASA scientists to conclude that four of Uranus' largest moons likely contain an ocean layer between their cores and icy crusts. Their study is the first to.....»»
New catalyst transforms carbon dioxide into sustainable byproduct
The need to capture CO2 and transport it for permanent storage or conversion into valued end uses is a national priority recently identified in the Bipartisan Infrastructure Law to move toward net-zero greenhouse gas emissions by 2050......»»
Study suggests catalyst for human brain evolution
More than a million years ago, large chunks of the human genome were rearranged—a chance event during egg or sperm formation that led to the deletion, duplication, or reversal of sections of DNA. Those structural variants, researchers have now disc.....»»
Record ammonia production achieved with inexpensive cobalt catalyst at low temperatures
Ammonia (NH3) is one of the most widely produced chemicals in the world, with production at more than 187 million tons in 2020. About 85% of it is used to produce nitrogenous fertilizers, while the rest is used for refining petroleum, manufacturing a.....»»
New stable isotope map of Angola helps archaeologists trace individual life histories across the African Diaspora
Archaeologists at UC Santa Cruz used predictive modeling to map strontium isotope ratios across all of modern-day Angola, a region in Southwest Africa that was once a major hub for the transatlantic slave trade. Researchers compared the resulting map.....»»
Paper highlights critical need for collaborative approach to green chemistry research
