Botswana diamond slump hits miners living on the edge of survival
Botswana diamond slump hits miners living on the edge of survival Botswana’s diamond-driven economy is under mounting strain as global demand weakens and production falls. Orapa, Botswana – It is a year since Motshwegwa Rakhudu lost his job after 14 years working as an installer at Debswana diamond mining operations in northern Botswana. He says he had been on rolling three-year renewable contracts with Enabler Hires (Pty) Ltd, and expected the arrangement would continue through to 2027.
New buried-growth process enables 2D arrays of position- and orientation-controlled diamond qubits
New buried-growth process enables 2D arrays of position- and orientation-controlled diamond qubits Sadie Harley Scientific Editor Robert Egan Associate Editor Researchers at Kanazawa University, in collaboration with Diamond and Carbon Applications (Germany), have developed a buried-growth process for nitrogen–vacancy (NV) centers in diamond using microwave plasma chemical vapor deposition (MPCVD). By employing nitrogen-radical selective etching, which simultaneously enhances metal-mask...
High-Purity Diamond Integration on $\beta$-Ga$_2$O$_3$ via Microwave Plasma CVD for Enhanced Thermal Management
arXiv:2511.08758v2 Announce Type: replace Abstract: The integration of diamond with $\beta$-Ga$_2$O$_3$ presents a promising pathway to enhance thermal management in high-power electronic devices, where the inherently low thermal conductivity of $\beta$-Ga$_2$O$_3$ can lead to localized self-heating and elevated junction temperatures. In this work, we demonstrate a scalable, low-damage approach for integrating polycrystalline diamond films on (010) $\beta$-Ga$_2$O$_3$ substrates via...
New route to tailor-made diamond nanoparticles holds promise for quantum applications
New route to tailor-made diamond nanoparticles holds promise for quantum applications Stephanie Baum Scientific Editor Robert Egan Associate Editor Nanodiamonds are tiny diamond particles only a few nanometers in size. Because they are chemically highly stable and can host so-called color centers, optically active defects in the crystal lattice, they are considered promising materials for quantum technologies, sensing and biomedical research. Until now, however, it has been difficult to...
Photorefractive tuning seeded by third-harmonic light in a diamond photonic crystal cavity
Announce Type: replace Abstract: Single-crystal diamond nanocavities have tremendous potential for use in quantum and nonlinear optical technologies. The ability to precisely control their resonant frequencies is essential for many applications, and $\textit{in situ}$ tuning is particularly desirable. In this work, we demonstrate deterministic resonance tuning of a diamond nanocavity.
Duplantis suffers shock defeat at Stockholm Diamond League
Duplantis suffers shock defeat at Stockholm Diamond League STOCKHOLM, June 7 : Olympic champion Armand Duplantis fell short of his bid for a world record at the Stockholm Diamond League on Sunday, suffering a surprise defeat as Australia’s Kurtis Marschall clinched victory with a clearance of 5.90 metres on his third attempt. The defeat ended a run of 40 straight victories for the 26-year-old, who admitted he had one eye on his upcoming wedding. "It was time to lose, it was a very long time...
Fresh blow to TMC as 9 councillors quit, Diamond Harbour board dissolved
In yet another setback for the Trinamool Congress ( TMC) following its rout in the recent Bengal assembly elections, the board of Diamond Harbour municipality was dissolved on Sunday. This came after nine of the party's councillors resigned, leading to the municipality going under administrative control. Diamond Harbour sub-divisional officer (SDO) Ayan Dattagupta has taken over as administrator of the civic body.

Lyles storms to victory, Alfred beats Jefferson-Wooden at Rome Diamond League
Lyles storms to victory, Alfred beats Jefferson-Wooden at Rome Diamond League ROME, June 4 : American Olympic champion Noah Lyles made a winning start to his Diamond League campaign in the men's 100 metres at the Rome meeting on Thursday, and Julien Alfred beat world champion Melissa Jefferson-Wooden in the women's 200 metres. Lyles was his usual confident self, soaking up the Stadio Olimpico crowd's applause before the final race of the night, and was typically bullish at the end. "I had a...
Intel Diamond Rapids to boost core counts to 192, but RIP Hyperthreading
Intel’s upcoming Diamond Rapids Xeon will boost core counts to 192, a 50 percent increase over last generation, the x86 giant revealed at Computex in Taipei this week. But while core counts continue to rise, in doing so Intel has managed to cut thread counts by a quarter. Yep, Hyperthreading – Intel's marketing for simultaneous multithreading – is officially dead.
