Osmium activation in cancer cells

Cancer is a complex disease, and as such, there is no single way to tackle it. While cancer treatments are evolving toward personalized procedures, in most cases, standard chemotherapy treatments are still required. In chemotherapy, ...

Extreme pressure causes osmium to change state of matter

Using metallic osmium (Os) in experimentation, an international group of researchers have demonstrated that ultra-high pressures cause core electrons to interplay, which results in experimentally observed anomalies in the ...

Record high pressure squeezes secrets out of osmium

An international team of scientists led by the University of Bayreuth and with participation of DESY has created the highest static pressure ever achieved in a lab: Using a special high pressure device, the researchers investigated ...

Diamonds grow like trees, but over millions of years

Diamonds consist of highly compressed carbon atoms and develop deep underground at relatively high pressures and temperatures of over 1000 degrees Celsius. Earth scientists from VU University Amsterdam show that diamonds ...

Osmium

Osmium ( /ˈɒzmiəm/ oz-mee-əm) is a chemical element with the symbol Os and atomic number 76. Osmium is a hard, brittle, blue-gray or blue-black transition metal in the platinum family, and is the densest natural element. Osmium is twice as dense as lead. The density of osmium is 22.59 g/cm3, slightly greater than that of iridium, the second densest element. Osmium is found in nature as an alloy, mostly in platinum ores. Osmium is also used in alloys, with platinum, iridium and other platinum group metals. Those alloys are employed in fountain pen tips, electrical contacts and in other applications where extreme durability and hardness are needed.
