Researchers Find New Phase of Carbon, Make Diamond at Room Temperature


Researchers from North Carolina State University have discovered a new phase of solid carbon, called Q-carbon, which is distinct from the known phases of graphite and diamond. They have also developed a technique for using Q-carbon to make diamond-related structures at room temperature and at ambient atmospheric pressure in air.

Phases are distinct forms of the same material. Graphite is one of the solid phases of carbon; diamond is another.

“We’ve now created a third solid phase of carbon,” says Jay Narayan, the John C. Fan Distinguished Chair Professor of Materials Science and Engineering at NC State and lead author of three papers describing the work. “The only place it may be found in the natural world would be possibly in the core of some planets.”

Gold beads may boost cancer treatment

Scientists are investigating whether microscopic gold beads could make chemotherapy more effective, and reduce side effects for patients.

The above image, which is from laboratory research conducted by Dr Andrew Thorley, from the National Heart and Lung Institute at Imperial College London, shows gold nanoparticles (in red) being absorbed into human cancer cells (the centre – or nucleus – of each cell is in blue, and the endosome - part of the cell’s internal transport system - is green).

Researchers coat the gold nanoparticles in chemotherapy drugs, and target them to the tumour, explains Dr Thorley, whose team presented their latest work at a recent meeting of the British Thoracic Society...

Colombia possibly discovers world's largest sunken treasure

sunken treasure

CARTAGENA, Colombia – President Juan Manual Santos on Saturday hailed the discovery of a Spanish galleon that went down off the South American nation's coast more than 300 years ago with what may be the world's largest sunken treasure.

At a news conference in this colonial port city, Santos said the exact location of the galleon San Jose, and how it was discovered with the help of an international team of experts, was a state secret that he'd personally safeguard. The ship sank somewhere in the wide area off Colombia's Baru peninsula, south of Cartagena...

Rapaport reports polished diamond prices rise in November

Scarcities, holidays and Chinese demand supporting prices with 0.30ct. RAPI +3%

(NEW YORK) - Polished diamond prices firmed in November supported by shortages of select categories and seasonal holiday demand. Trading improved with dealers focused on filling U.S. holiday orders, but old challenges remain: Manufacturing is unprofitable at current rough price levels and the diamond distribution chain is overstocked, despite some scarcities. The RapNet Diamond Index (RAPI™) for 1-carat, GIA-graded diamonds rose 0.7 percent in November, its first increase in six months. RAPI for 0.30-carat diamonds advanced 3.3 percent and RAPI for 0.50-carat diamonds grew 1.1 percent. RAPI for 3-carat diamonds fell 0.6 percent. RAPI for 1-carat diamonds remains down 7.1 percent since the beginning of the year.

Savani said he first stepped in to play the role of the father in 2008, when one of his employees died a few days before the weddings of his two daughters...
