'Frozen' copper behaves as noble metal in catalysis: study
As a non-noble metal, copper oxidizes more easily to a positive valence (Cu+ or Cu2+) than same-family elements Au or Ag. In general, this chemical property is mainly determined by electron structure. Can we change the chemical ...
Measuring individual argon atoms helps in understanding ocean ventilation
The age of the water in the world's oceans is critical for understanding ocean circulation, especially for the transport of gases from the atmosphere into the deep ocean. Researchers from Heidelberg University recently used ...
'Fudge factors' in physics?
Science is poised to take a "quantum leap" as more mysteries of how atoms behave and interact with each other are unlocked.
Taking the temperature of protoDUNE
When crane operators at CERN lowered a custom 7.5-metre thermometer into one of the prototypes for the planned Deep Underground Neutrino Experiment (DUNE) earlier this month, it looked like a silver straw sliding into a giant ...
ICARUS neutrino detector installed in new Fermilab home
For four years, three laboratories on two continents have prepared the ICARUS particle detector to capture the interactions of mysterious particles called neutrinos at the U.S. Department of Energy's Fermi National Accelerator ...
Scientists investigating mysterious dark matter
University of Houston scientists are helping to develop a technology that could hold the key to unraveling one of the great mysteries of science: what constitutes dark matter? Scientists believe dark matter makes up 85 percent ...
Physicists contribute to dark matter detector success
In researchers' quest for evidence of dark matter, physicist Andrea Pocar of the University of Massachusetts Amherst and his students have played an important role in designing and building a key part of the argon-based DarkSide-50 ...
How to produce the purest argon ever
CERN is taking part in a project, called ARIA, for the construction of a 350-metre-tall distillation tower that will be used to purify liquid argon (LAr) for scientific and, in a second phase, medical use.
We're building a 1,300km-long underground science experiment to study the world's most elusive particles
In an abandoned gold mine close to Deadwood, South Dakota, construction has started on what is arguably the world's largest science experiment. I'm part of an international team of around 1,000 scientists assembled to design ...
