Traditional Li batteries utilizing graphite as an anode material face significant challenges when operating in cold temperatures, particularly below freezing. Graphite’s storage capacity decreases, and the formation of dendrites on the anode surface during charging can pose safety risks, including thermal runaway and potential explosions. These drawbacks have paved the way for the development of

The emergence of self-driving vehicle networks that collaborate and communicate with each other or with infrastructure to make decisions has brought forth a new set of challenges. According to a recent study led by the University of Michigan, these networks are vulnerable to data fabrication attacks. This study, presented at the 33rd USENIX Security Symposium
AMD’s recent announcement of the acquisition of server maker ZT Systems in a $4.9 billion cash-and-stock deal has caught the attention of the tech industry. This move is part of AMD’s strategic plan to enhance its artificial intelligence capabilities to compete with industry giant Nvidia. However, this acquisition is not without its challenges and potential
A recent ruling by a US judge has labeled Google as a monopoly, signaling that the tech giant has been using its dominant position in the market to solidify its status further. This decision aligns with the European Commission’s approach towards regulating tech giants like Google, Meta, and Amazon. The acknowledgment that companies like Google
The recent shift in Donald Trump’s stance on cryptocurrency, demonstrated at the Bitcoin 2024 conference in Nashville, is a significant departure from his previous skepticism. Once a vocal critic, Trump now presents himself as a champion of digital assets, aligning with the emerging trend of “PolitiFi,” where politics and crypto intersect. President Joe Biden’s administration,
Boeing’s new CEO, Kelly Ortberg, has expressed a desire to “reset” the company’s relationship with a key union representing thousands of its workers as they navigate negotiations for a new labor contract. This move comes after Ortberg took office just a week ago and seeks to address concerns surrounding the expiration of the current 16-year-old
The issue of safety surrounding e-scooters has been a significant topic of debate, particularly in cities like Melbourne. Recently, the City Council voted to break contracts with operators of shared e-scooter schemes due to safety concerns. However, when looking at the bigger picture, it becomes apparent that knee-jerk reactions to safety issues may be overshadowing
Epic Games, the mastermind behind the global phenomenon Fortnite, has taken a bold step by launching its very own app store. This move allows users to bypass the established stores of tech giants Apple and Google, marking a significant shift in the mobile gaming industry. After years of legal battles and advocacy efforts, Epic Games
Lithium-metal batteries have long been hailed as the next big advancement in battery technology, with the potential to significantly surpass the energy densities of current lithium-ion batteries. However, despite their promise, lithium-metal batteries have been plagued by issues such as short lifespans and the formation of lithium dendrites. These limitations have prevented the widespread adoption
Over the past few years, roboticists have been working tirelessly to create robotic grippers that can effectively pick up and manipulate various objects. While many grippers are inspired by the versatility of the human hand, they often come with complex mechanisms and advanced programming tools that make them impractical for wide-scale deployment. However, researchers from
