The findings suggest that DBIBB shows promise for becoming the first drug capable of treating acute radiation syndrome caused by the high levels of radiation released by nuclear explosions."

"Nuclear explosions can expose humans to high levels of ionizing radiation, which can cause cell death and organ injury due to DNA damage.

#China and India race to fully harness thorium for nuclear power Thorium is an alternative to uranium as a way of doing nuclear fission.

Thorium is an alternative to uranium as a way of doing nuclear fission he told Metro.

who point to its nuclear reaction producing U-232, the decay products of which contain gamma radiation. And many supporters of green energy believe the nuclear equation should be abandoned

That phenomenon known as singlet exciton fission was identified first in the 1960s. However, achieving it in a functioning solar cell has proved difficult

Exciton fission has now been observed in a variety of materials all discovered like the original ones by chance. e can rationally design materials

and devices that take advantage of exciton fission until we understand the fundamental mechanism at work until we know what the electrons are actually doing,

The samples were made of four types of exciton fission molecules decorated with various sorts of pinachbulky side groups of atoms that change the molecular spacing without altering the physics or chemistry.

To detect fission rates which are measured in femtoseconds (10-15 seconds) the MIT team turned to experts including Moungi Bawendi, the Lester Wolfe Professor of Chemistry,

Van Voorhisnew first-principles formula successfully predicts the fission rate in materials with vastly different structures.

They show that molecular packing is important in defining the rate of fission but only to a point.

considers the new findings very important contribution to the singlet fission literature. Via a synergistic combination of modeling, crystal engineering,

and experiment, the authors have provided the first systematic study of parameters influencing fission rates, he says.

Their findings hould strongly influence design criteria of fission materials away from goals involving molecular packing

gigantic particle detectors at four interaction points along the ring record the proton collisions that are generated

That's a lot of collision data, says SMU physicist Robert Kehoe, a member of the ATLAS particle detector experiment with Stroynowski and other SMU physicists.

Data from the ATLAS particle detector's Liquid Argon Calorimeter is transmitted via 1 524 small fiber-optic transmitters.

These quarks are bound together by strong nuclear force.''In particle physics, every force is mediated by a special kind of force particle,

and the force particle of the strong nuclear force is said the gluon Anton Rebhan (TU Wien).

while eight different kinds of gluons play a similar role for the strong nuclear force. However, there is one important difference:

of pure nuclear force, is theoretically possible. Several particles have been found in particle accelerator experiments which are considered to be viable candidates for glueballs.

Russian scientist Natalya Pugach from the Skobeltsyn Institute of Nuclear physics at the Lomonosov Moscow State university discovered this yet to be explained effect with her British colleagues,

which included Natalya Pugach from the Skobeltsyn Institute of Nuclear physics, studied the interactions between superconductivity

Skyrmions were described originally over 50 years ago as a type of hypothetical particle in nuclear physics. Actual magnetic skyrmions were discovered only in 2009,

since it is based on nuclear reactions in ultra-dense heavy hydrogen (deuterium).""This is a considerable advantage compared to other nuclear fusion processes

#Scientists say theye found a particle made entirely of nuclear force After decades of searching, scientists say theye finally identified a glueball-a particle made purely of nuclear force.

Hypothesised to exist as part of the standard model of particle physics, glueballs have eluded scientists since the 1970s because they can only be detected indirectly by measuring their process of decay.

gluons are in charge of exerting a strong nuclear force.""In particle physics, every force is mediated by a special kind of force particle,

and the force particle of the strong nuclear force is the gluon, "explains one of the researchers, Anton Rebhan from the Vienna University of Technology.

gluons can be bound together via their own nuclear force to form glueballs.""The existence of glueball particles brings the idea that,

the researchers demonstrated the material's potential for creating high-performance, low-cost, room-temperature semiconductor radiation detectors. In a paper published this week in the Journal of Applied Physics, from AIP Publishing,

Du's research established a theoretical foundation for the development of thallium sulfide iodide radiation detectors, opening doors for a new generation of room-temperature semiconductor radiation detectors.

The Limits of Conventional Radiation Detectorssemiconductor radiation detectors are devices that measure ionizing radiation by collecting radiation-generated charge carriers in the semiconductor between electrodes under a bias voltage.

In recent years, scientists have been seeking new materials for room-temperature radiation detectors. A semiconductor material called cadmium zinc telluride (Cdznte) has been found to be the best candidate to date,

and can be used to create a thinner, low-cost radiation detector. A good radiation detection material should have efficient charge transport property,

Studying the native defects and their effects on charge transport in a material are hence essential for the performance improvement of a radiation detector.

low melting temperature and so on, suggest that thallium sulfide iodide is a good candidate for fabricating new generation room-temperature radiation detectors with improved performance and lower cost than previous detectors,

Along with gravity the electromagnetic interaction and weak nuclear force strong-interactions are one of four fundamental forces. Lead scientist Professor Tim Gershon from The University of Warwick's Department of physics explains:

Nuclear fusion could produce far more energy far more cleanly than the fission reactions at the heart of today s nuclear power plants.
