Strained Diamond Electronics

Researchers at City University of Hong Kong (CityU) have demonstrated large, uniform tensile elastic straining of microfabricated diamond arrays through the nanomechanical approach. This has the potential of strained diamonds as prime candidates for advanced functional devices in microelectronics, photonics, and quantum information technologies. Above – CAPTION Stretching of microfabricated diamonds pave ways for applications …

Carbon Nanostructure Stronger than Diamond By Strength to Density

Researchers have architecturally designed plate-nanolattices – nanometer-sized carbon structures – that are stronger than diamonds as a ratio of strength to density. The team’s design has been shown to improve on the average performance of cylindrical beam-based architectures by up to 639 percent in strength and 522 percent in rigidity. They designed and fabricating the …

Nanostructured Diamond Metalens For Compact Quantum Technologies

The key to harnessing the potential power of quantum systems is being able to create or find structures that allow electron spin to be reliably manipulated and measured, a difficult task considering the fragility of quantum states. Bassett’s lab at the University of Pennsylvania approaches this challenge from a number of directions. Recently, the lab …

Demo of two-qubit fault-tolerant universal holonomic quantum gates could enable faster quantum computers

Japases researchers have demonstrated holonomic quantum gates under zero-magnetic field at room temperature, which will enable the realization of fast and fault-tolerant universal quantum computers. A quantum computer is a powerful machine with the potential to solve complex problems much faster than today’s conventional computer can. Researchers are currently working on the next step in …

Six inch wide diamond disks guide megawatt of microwave heating for nuclear fusion

Researchers of Karlsruhe Institute of Technology (KIT) and the company Diamond Materials have developed 6 inch wide diamond disks for window units to heat the plasma in fusion reactors. Gyrotrons are microwave oscillators generating a temperature of up to 150 million degrees Celsius in the reactor, similar to a very big microwave. This high temperature …

Synthetic diamond will enable quantum networks

Princeton University researchers are using synthetic diamonds to help create a quantum communication network. Quantum information networks could be extremely secure and could also allow new quantum computers to work together to solve currently unsolvable problems. The main problem has been to preserve fragile quantum information over long distances. Researcher were able to store and …

Synthetic diamonds are in jewelry stores for about 40% lower cost

Ada Diamonds offers only laboratory-grown diamonds in our fine jewelry. Ada’s sustainably cultured diamonds have the exact same crystal structure, chemical composition, optical properties, and physical properties as mined diamond. Ada’s gemstones are graded on the exact same criteria as mined diamonds (the Four Cs), by the same independent gemological laboratories that grade Earth-extracted diamonds. …

Two-Layer Graphene becomes a Diamond-Hard Material on Impact which could make super armor

Scientists at the Advanced Science Research Center (ASRC) at the Graduate Center, CUNY, worked to theorize and test how two layers of graphene — each one-atom thick — could be made to transform into a diamond-like material upon impact at room temperature. The team also found the moment of conversion resulted in a sudden reduction …

Stanford lab makes nanodiamond rain but on Uranus and Neptune diamonds would be millions of carats

Stanford Linear Accelerator Lab (SLAC) scientists were able to observe “diamond rain” for the first time as it formed in high-pressure conditions. Extremely high pressure squeezes hydrogen and carbon found in the interior of these planets to form solid diamonds that sink slowly down further into the interior. The glittering precipitation has long been hypothesized …
