Nuclear Reactions Are Smoldering Again At Chernobyl
An anonymous reader quotes a report from Science Magazine: Thirty-five years after the Chernobyl Nuclear Power Plant in Ukraine exploded in the world's worst nuclear accident, fission reactions are smoldering again in uranium fuel masses buried deep.....»»
Researchers reveal atomic-scale details of catalysts" active sites
The chemical and energy industries depend upon catalysts to drive the reactions used to create their products. Many important reactions use heterogeneous catalysts—meaning that the catalysts are in a different phase of matter than the substances th.....»»
Researchers dig deeper into stability challenges of nuclear fusion—with mayonnaise
Mayonnaise continues to help researchers better understand the physics behind nuclear fusion......»»
Engineers develop general, high-speed technology to model, understand catalytic reactions
Researchers have been studying the industrial production of ammonia for a century. But they've struggled to find ways to improve the low-yield, low-efficiency process......»»
Researchers develop a concept for efficiency-enhanced noble-metal catalysts
The production of more than 90% of all chemical products we use in our everyday lives relies on catalysts. Catalysts speed up chemical reactions, can reduce the energy required for these processes, and in some cases, reactions would not be possible a.....»»
A study examined reactions of Jewish Israelis to human rights criticism; then Oct. 7 happened
A UC Merced professor and his co-researchers set out to measure how Jewish Israelis react to different sources of criticism about Israel's treatment of Palestinians. Does disapproval from internal voices move public opinion? Voices from abroad? What.....»»
A modified model designed to simulate nuclear fission sheds light on how rumors start, spread, and end
It has never been easier to spread false or misleading information online. The anonymous, impersonal nature of the internet, combined with advanced tools like artificial intelligence, makes it trivial for bad actors to manipulate the truth and challe.....»»
Physicists introduce method for mechanical detection of individual nuclear decays
In recent years, physicists and engineers have developed increasingly sophisticated instruments to study particles and the interactions between them with high precision. These instruments, which include particle detectors, sensors and accelerometers,.....»»
Liquid metals offer potential for greener chemical processes, researchers say
University of Sydney researchers are proposing a new way to curb industrial emissions, by tapping into the "atomic intelligence" of liquid metals to deliver greener and more sustainable chemical reactions......»»
We’re building nuclear spaceships again—this time for real
The military and NASA seem serious about building demonstration hardware. Enlarge / Artist concept of the Demonstration for Rocket to Agile Cislunar Operations (DRACO) spacecraft. (credit: DARPA) Phoebus 2A, the most pow.....»»
Results suggests titanium-48"s nuclear structure changes when observed at varying distances
The world around us is made up of particles invisible to the naked eye, but physicists continue to gain insights into this mysterious realm. Findings published in Physical Review C by Osaka Metropolitan University researchers show that the nuclear st.....»»
Forest monitoring reveals self-cleansing effect of radiocesium in ecosystem after Fukushima Daiichi plant accident
A forest monitoring survey conducted more than 13 years after the Fukushima Daiichi Nuclear Power Plant accident has revealed that the natural downward migration of radiocesium in soil exhibits a decontamination effect that reduces the air dose rate.....»»
3D visualization brings nuclear fusion to life
When it comes to promising forms of energy, nuclear fusion checks all the boxes: it's clean, abundant, continuous and safe. It's produced when the lightweight nuclei of two atoms fuse together to form a heavier nucleus, releasing large amounts of ene.....»»
CERN physicist explains how team uses subatomic splashes to restart experiments after annual upgrades
When you push "start" on your microwave or computer, the device flips right on—but major physics experiments like the Large Hadron Collider at the European Organization for Nuclear Research, known as CERN, don't work that way. Instead, engineers an.....»»
First observation of the nuclear two-photon decay in bare atomic nuclei
For the first time, an international research team has succeeded in observing a two-photon decay on a so-called bare atomic nucleus from which the entire electron shell has been removed......»»
Physicists pool skills to better describe the unstable sigma meson particle
While nuclear physicists know the strong interaction is what holds together the particles at the heart of matter, we still have a lot to learn about this fundamental force. Results published earlier this year in Physical Review D by three researchers.....»»
Observatory gears up to detect thousands of elusive brown dwarfs, unlocking Milky Way mysteries
One could argue that brown dwarfs don't get the love they deserve. Sometimes referred to as "failed stars," they don't have enough mass to sustain nuclear fusion, which powers all stars, including our sun. But they are also too big to be considered p.....»»
Zero-field NMR spectroscopy measures quadrupolar nuclei for the first time
Researchers at Mainz University and the University of California, Berkeley, have achieved a breakthrough in zero-field nuclear magnetic resonance spectroscopy, paving the way towards benchmarking quantum chemistry calculations......»»
RCS update standardizes message replies, editing, reactions, more for Android & iPhone
The GSMA Association (GSMA) is responsible for maintaining Rich Communication Services (RCS) and the latest update to the standard adds “Extended Messaging” that should improve Android and iPhone interoperability. more….....»»
Tensor-force effects on nuclear matter in relativistic ab initio theory
Tensor force is a crucial ingredient of the nucleon-nucleon (NN) interaction, and has an important impact on the structural and dynamical properties of the nuclear many-body system. Many efforts have been devoted to studying the influence of the tens.....»»
Researchers predict new phase in neutron stars that favors "nuclear pasta"
Neutron stars are extreme and mysterious objects that astrophysicists cannot see inside. With a radius of around 12 kilometers, they can have more than twice the mass of the sun. The matter in them is packed up to five times as densely as in an atomi.....»»
