Researchers have discovered mechanisms critical to interactions between hot plasma and surfaces facing the plasma inside a thermonuclear fusion reactor, part of work aimed at developing coatings capable of withstanding the grueling conditions inside the reactors. Fusion powers the stars and could lead to a limitless supply of clean energy. A fusion power plant would produce 10 times more energy than a conventional nuclear fission reactor, and because the deuterium fuel is contained in...

By swapping out one specific hydrogen atom for an isotope twice as heavy, researchers have increased the shelf life and detection ability of fluorescent probes that are essential to studying a variety of inflammatory diseases, including cancer and atherosclerosis. The probes detect and measure reactive oxygen species, which play an important role in disease processes. "By replacing a hydrogen atom with a deuterium atom during the synthesis of several fluorescent probes, we increased the...

A new process for storing and generating hydrogen to run fuel cells in cars has been invented by chemical engineers at Purdue University. The process, given the name hydrothermolysis, uses a powdered chemical called ammonia borane, which has one of the highest hydrogen contents of all solid materials, said Arvind Varma, R. Games Slayter Distinguished Professor of Chemical Engineering and head of the School of Chemical Engineering. "This is the first process to provide exceptionally high...

The scalding-hot sea that supposedly covered the early Earth may in fact never have existed, according to a new study by Stanford University researchers who analyzed isotope ratios in 3.4 billion-year-old ocean floor rocks. Their findings suggest that the early ocean was much more temperate and that, as a result, life likely diversified and spread across the globe much sooner in Earth's history than has been generally theorized. It also means that the chemical composition of the ancient ocean...

The U.S. construction of the National Ignition Facility (NIF) is complete and researchers are preparing to start the first experiments aimed at recreating conditions at the heart of our Sun, BBC News reported. Scientists hope the experiments will demonstrate the feasibility of nuclear fusion, a process that could offer abundant clean energy. They will begin by focusing 192 giant laser beams on a tiny pellet of hydrogen fuel, in hopes they can show that more energy can be extracted from the...

New evidence for existence of controversial energy source Researchers are reporting compelling new scientific evidence for the existence of low-energy nuclear reactions (LENR), the process once called "cold fusion" that may promise a new source of energy. One group of scientists, for instance, describes what it terms the first clear visual evidence that LENR devices can produce neutrons, subatomic particles that scientists view as tell-tale signs that nuclear reactions are occurring....

Deuterated pyridine adopts a different crystalline form: a useful effect for pharmaceuticals?The nuclei of ordinary hydrogen atoms contain only a single proton. If a neutron is added, the hydrogen becomes deuterium. In principle, molecules that contain deuterium in place of hydrogen atoms are chemically identical. However, there can be significant differences. Thus "heavy water", water with molecules that contain deuterium in place of hydrogen, is toxic because it disrupts highly sensitive...

Concert Pharmaceuticals, Inc. today announced findings from a preclinical study suggesting that C-20081, a novel, deuterium-containing oxazolidinone antibiotic, may be suitable for once-daily oral and intravenous dosing. In the preclinical study, C-20081 had a 43% increase in plasma half-life compared to linezolid, which might allow for lower overall drug exposure and improved tolerability with a once-daily dose. These findings were presented in a poster presentation at the 48th Annual...

Concert Pharmaceuticals, Inc. announced today that it has initiated a Phase I study in healthy volunteers to evaluate the safety, tolerability and pharmacokinetics of CTP-347, a novel deuterium-containing serotonin modulator created by Concert researchers. Concert intends to evaluate CTP-347 as a non-hormonal treatment for vasomotor symptoms (VMS or hot flashes) in patients with increased risk of adverse effects due to, or contraindicated to using, hormone therapy, as well as in the larger...

By Castelvecchi, Davide Bond lengths are different in heavy, light water molecules Heavy water is not just heavier. Swapping each H in H2O with a D- hydrogen's isotope deuterium - changes water's properties. The deuterium version is mildly poisonous, and its freezing point is 4[degrees] Celsius, instead of 0[degrees]C Such differences reveal that quantum effects, which aren't usually manifest to the naked eye, rule in ordinary water, researchers suggest. Alan Soper of the Rutherford...

cacodemon
  • An evil spirit; a devil.
  • A nightmare.
  • In astrology, the twelfth house of a scheme or figure of the heavens: so called from its signifying dreadful things, such as secret enemies, great losses, imprisonment, etc.
