This significant development could put an end to PC overheating concerns for good

A little-known compound could dethrone silicon in the near future

Silicon may be the de facto standard for computers today, but new research from MIT, the University of Houston, and other schools suggests that it may be time for a shift.

Cubic boron arsenide, a compound molecule created by combining boron and arsenic, may be a better semiconductor, circumventing some of silicon's shortcomings in terms of heat sensitivity.

Cubic boron arsenide, in fact, has the "third-best thermal conductivity of any material — next to diamond and isotopically enriched cubic boron nitride," according to study published in Science.

Is this what the future holds?

More research is needed to determine whether cubic boron arsenide can be "produced in a viable, inexpensive form, much less replace the omnipresent silicon," according to the study.

However, the researchers believe that the material could find "certain usage where its unique features would make a substantial impact" in the near future.

Having said that, the study showed the compound's enormous potential.

Cubic boron arsenide appears to be far more tolerant of "holes," electrons' positively charged counterparts.

Cubic boron's reduced heat sensitivity could possibly make a significant difference.

"Heat is now a serious constraint for many devices," said co-author and MIT postdoc Jungwoo Shin. "Silicon carbide is replacing silicon for power electronics in major EV sectors such as Tesla because it has three times the heat conductivity of silicon despite having lower electrical mobilities." 

"Consider what boron arsenides can accomplish, with 10 times the heat conductivity and mobility of silicon. It has the potential to be a game changer."

Not only is cubic boron arsenide threatening to supplant silicon one day.

University of Illinois researchers created 4-bit and 8-bit processors entirely out of plastic, with an 81 percent success rate, at least for the 4-bit ones

It's worth noting that silicon never truly had a monopoly in the area of semiconductors.

Gallium arsenide, a compound composed of gallium and arsenic, is a popular alternative to silicon in lasers.

Bliv. Club and WIOM work with Shikhar Dhawan to introduce the first metaverse sports metropolis

Shikhar Dhawan, a cricket player, has announced his collaboration with Web3 companies Bliv. Club, a finance company, and WIOM, a Web3 Metaverse company, to introduce the first sports city in the Metaverse. Serial businessmen Vikas Singh, Abhishek Kumar Gupta, and Mohammed Sirajuddin established Bliv.Club in 2021. World in One Metaverse (WIOM), a Web3 Metaverse firm, was founded by award-winning digital entrepreneur and IIT Delhi graduate Abhinav Tandon. Credit: IMDB The global sports market is projected to rise from $354.96 billion in 2021 to $501.43 billion in 2022, at a compound annual growth rate (CAGR) of 41.3 percent. At a CAGR of 9%, the sports market is anticipated to reach $707.84 billion in 2026. From 2022 to 2030, the global metaverse market is anticipated to expand at a compound yearly growth rate of more than 45.8%, reaching a market size of more than $1,803 billion. Shikhar Dhawan was inspired by this to establish a sports metropolis in the Metaverse. The Da-One group of b

NFT Rollout in 100 Countries Confirmed by Meta Amid Coinbase Integration

NFT integration is currently active on Instagram in 100 countries after several testing phases The world's largest social networking company, Meta (META), has integrated with Coinbase (COIN) Wallet and Dapper and is now distributing non-fungible tokens (NFT) across 100 nations. Mark Zuckerberg, the creator and CEO of Meta, announced the rollout in a Facebook post. After a successful testing period in May, Instagram users in several countries can now display their NFTs. According to a tweet from Meta, the social media network will also include support for Flow Blockchain. The goal of the testing was to enable cross-platform posting utilising NFTs, according to Meta product manager Navdeep Singh, who stated last month that testing was also going on on Facebook.
