Intel is trying to keep up with the exploding demand for new computing horsepower.
In what is being seen as a shift from silicon, Intel announced Monday their progress in commercializing glass substrates toward the end of the decade. The company said that glass substrates are an improvement in design, allowing more transistors to be connected in a package and will help overcome the limitations of organic materials.
As the world advances to incorporate developments in data-intensive workloads in artificial intelligence, glass substrates, in comparison to organic substrates,⊠More.

Intel says its new glass substrate will help the company create more powerful processors with better production yields.
This is a room temperature superconductor it is called graphene đ.
A large violation of the Pauli limit and re-entrant superconductivity in a magnetic field is reported for magic-angle twisted trilayer graphene, suggesting that the spin configuration of the superconducting state of this material is unlikely to consist of spin singlets.

A team of researchers led by Seung-Cheol Lee, director of the Indo-Korea Science and Technology Center(IKST) at the Korea Institute of Science and Technology (KIST), developed a method to predict the distribution of molecules on the surface using the magnetoresistance property of MXene, according to a statement by the scientists.
âIn particular, the wind turbine sector uses very large quantities of a rare earth magnet thatâs an alloy of neodymium, iron and boron (NdFeB). These NdFeB magnets are critical components used in PMSGs (Permanent Magnet Synchronous Generator) in larger onshore and offshore wind turbinesâ.

Named Re-Rewind, the partnership, partly funded by Innovate UK, aims to establish the UKâs first circular supply chain for the rare earth magnets used in wind turbines.
âFrom high-quality construction steel, copper and other metals to a range of rare earth elements (such as praseodymium and dysprosium), modern wind turbines contain a wealth of materials which, if they cannot be sourced from recycled channels, must be mined, leading to increased environmental impacts and resource scarcityâ, the newly created partnership states.
This device can generate deep-UV light with a very narrow wavelength range that is safe for humans but lethal for germs.
A new device that can generate deep-ultraviolet (UV) light to kill germs without harming humans has been developed by a team of researchers from Osaka University, Japan. The device uses a novel method of combining two visible photons into one deep-UV photon inside a thin waveguide made of aluminum nitride, a material that has nonlinear optical properties.
The research, named â229 nm far-ultraviolet second harmonic generation in a vertical polarity inverted AlN bilayer channel waveguide,â has been published in the journal Applied Physics Express.
Scientists and engineers keep developing ever faster and more powerful technological devices. But there is a need for even faster and more efficient electronics. A promising route is to take advantage of terahertz waves, a less-explored part of the electromagnetic spectrum nestled between the infrared and microwave regions. Terahertz waves are uniquely sensitive to charge carriers in conducting systems, proving a powerful probe to understand the magnetic properties of new materials.
The quest for ultrafast electronics and coherent terahertz sources can be significantly aided by the precise and ultrafast control of light-induced charge currents at nanoscale interfaces.
Existing methods, including inverse spin-Hall effect (ISHE), inverse RashbaâEdelstein effect, and inverse spin-orbit-torque effect, convert longitudinally injected spin-polarized currents from magnetic materials to transverse charge currents, thus generating terahertz waves. However, these relativistic mechanisms rely on external magnetic fields and suffer from low spin-polarization rates and relativistic spin-to-charge conversion efficiencies characterized by spin-Hall angle.
