Intel says there will be one trillion transistors on chips by 2030

Year 2022 😗😁

During the IEEE International Electron Devices Meeting (or IEDM), Intel claimed that by 2030, there would be circuits with transistor counts of a trillion, roughly ten times the number of transistors currently available on modern CPUs.

At the meeting, Intel’s Components Research Group laid down its prediction for the future of circuits manufacturing (via sweclockers) and how new packaging technologies and materials will allow chipmakers to build chips with 10x the transistor density, keeping in Moore’s Law.

Zambia site shows humans made wood structures 500k years ago

Professor Geoff Duller from Aberystwyth University explained that, given the considerable age of these artifacts, assigning precise dates to them presented a significant challenge. To address this issue, luminescence dating techniques were employed. These innovative dating methods have broad-ranging implications, enabling the dating of much older materials and facilitating the reconstruction of sites that offer insights into human evolution—in the case of Kalambo Falls, an excavation conducted in the 1960s yielded comparable wooden fragments. Still, their dating had remained elusive, leaving the true importance of the site uncertain until now.

Kalambo Falls is located on the Kalambo River above a 772-foot (235-meter) waterfall on the border of Zambia and Tanzania near Lake Tanganyika. The area is on a ‘tentative ‘list from UNESCO for becoming a World Heritage site because of its archaeological significance.

MIT Engineers Harness Kirigami for Ultrastrong and Lightweight Structures

Produced with techniques borrowed from Japanese paper-cutting, the strong metal lattices are lighter than cork and have customizable mechanical properties.

Cellular solids are materials composed of many cells that have been packed together, such as a honeycomb. The shape of those cells largely determines the material’s mechanical properties, including its stiffness or strength. Bones, for instance, are filled with a natural material that enables them to be lightweight, but stiff and strong.

Inspired by bones and other cellular solids found in nature, humans have used the same concept to develop architected materials. By changing the geometry of the unit cells that make up these materials, researchers can customize the material’s mechanical, thermal, or acoustic properties. Architected materials are used in many applications, from shock-absorbing packing foam to heat-regulating radiators.

Intel’s glass substrate promises 1T transistors by 2030

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.

Intel says its new glass substrate will help the company create more powerful processors with better production yields.

Extract Rare Earth Magnets from Retired Wind Turbines

“In particular, the wind turbine sector uses very large quantities of a rare earth magnet that’s 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 turbines”.

Extracting the rare earth magnets from end-of-life wind turbines and enabling their use in new wind turbines, both onshore and offshore

Named Re-Rewind, the partnership, partly funded by Innovate UK, aims to establish the UK’s first circular supply chain for the rare earth magnets used in wind turbines.

“From 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 scarcity”, the newly created partnership states.
