said Dr. Wen H. Shen, the study lead investigator and an assistant professor of cell biology in radiation oncology at Weill Cornell. ased on our research,
According to Syracuse physicist Sheldon Stone, graduate student Nathan Jurik was studying the decay of a different particle
The group found the pentaquarks by examining the decay of a particular kind of baryon known as Lambda b. hile existence of pentaquarks was speculated on since the beginning of the quark model in 1964,
#Metal foam provides lightweight radiation shielding Nuclear, space exploration and medical applications abound for low-density, nontoxic structural shielding materials Lightweight composite metal foams can absorb energy from impacts
and block X-rays, gamma rays and neutron radiation, according to a study from North carolina State university. The discovery means the materials could be useful in spacecraft, the nuclear industry and in medicine.
whether they could provide structural support while also shielding from radiation. Her research involved comparing foamsshielding properties against pure lead and the A356 grade of aluminium, metals that are used currently for shielding purposes.
because tungsten and vanadium both have good radiation shielding properties. The tungsten-containing foam was modified
The researchers found that the high-Z foam was as good as the bulk materials at blocking high-energy gamma rays,
such as the radiation from barium an americium. It outperformed bulk materials at blocking neutron radiation, and was bettered only by lead at blocking X-rays. owever,
in protecting equipment onboard exploratory spacecraft from the high radiation fluxes sometimes found in space without adding significantly to their weight,
and in protecting patients from radiation doses in CT SCANNERS. The team discusses its work in a paper in the journal Radiation Physics and Chemistry a
#Tiny'wrist'to assist needle surgery A tiny flexible wrist component for needle-sized surgical equipment could enable surgeons to perform operations in tiny spaces
