Diamondiferous garnet harzburgites from the Finsch kimberlite, Northern Cape, South Africa Two xenoliths of garnet harzburgite from the Finsch kimberlite, South Africa, have been found to contain diamond. One of the xenoliths has mineral composit... KS Viljoen,PM Swash,ML Otter,... - 《Cont...
Their presence in the kimberlite should be diagnostic of the presence of diamond, but it is not known if there is any quantitative relationship. The garnets are considered to have a deeper provenance than the magnesian garnets commonly found as xenocrysts in kimberlite and in garnet peridotite ...
The Cullinan mine, located on a diamond-bearing kimberlite pipe in the Gauteng province of South Africa, is the world’s richest source of rare blue diamonds and has produced more than a quarter of the world’s diamonds that are greater than 400 carats. The massive mine is also a scientifi...
His many adventures — from diamond mining in South Africa to riding the rails in India — ended up bringing one of his last works of travel writing, Following the Equator, into existence. Though Twain was considerably older and sadder by this time, this book bears witness to the fact that...

A part of the sample was excavated with a FIB system, JEOL JEM-9320FIB, and the extracted slice was placed on a culet of single diamond. The excavated samples on the diamond were scanned at the BL10XU beam line (SPring-8). A monochromatic incident X-ray beam with a wavelength of ...
New research led by Professor Somnath Bhattacharyya in the Nano-Scale Transport Physics Laboratory (NSTPL) in the School of Physics at the University of the Witwatersrand in Johannesburg, South Africa, details the phenomenon of what is called “triplet superconductivity” in diamond. Tr...
The radio-emitting neutron star population encompasses objects with spin periods ranging from milliseconds to tens of seconds. As they age and spin more slowly, their radio emission is expected to cease. We present the discovery of an ultra-long-period r
and irradiated products. The Environment and Energy segment includes copper wire rods, electric power cables, magnet wires, power systems, and supervisory telecontrol equipment. The Industrial Materials and Others segment consists of special steel wires, cutting tools, diamond and cubic boron nitride too...
of artificial intelligence systems in disease diagnostics and treatment design is growing, and this is expected to witness robust growth in the coming years. For instance, in March 2020, Existencia, an AI-based drug discovery company, entered a collaborative agreement with Diamond Light Source and ...
