A simple, highly efficient, inexpensive, and environmentally friendly process could provide a viable pathway for the sustainable recycling of depleted lithium-ion batteries (LIBs): No chemicals beyond citric acid need to be added to leach out and separate over 99% of the lithium, nickel, cobalt, and manganese metals contained in NCM batteries. The resulting recycled material […]
Vehicles fueled by diesel lead to substantial carbon emissions that are challenging to decarbonize. In 2022, diesel fuel use made up about one-fourth of total U.S. transportation carbon dioxide emissions and about one-tenth of total energy-related carbon dioxide emissions, according to the U.S. Energy Information Administration. Joshua Yuan, the Lucy & Stanley Lopata Professor and […]
Batteries are fueling drone warfare. Reconnaissance quadcopters with a half-hour of flying time require a constant supply of freshly recharged batteries to keep going. Bomber drones eat up similar numbers. FPV drones are shipped with batteries that weigh more than the drones themselves. Most drone batteries are made in China, which is why the Chinese […]
As the demand for electricity rises in the age of artificial intelligence (AI), global tech companies are focusing on small nuclear reactors as a sustainable energy solution. A new remote monitoring technology using advanced AI is capable of detecting potential hazards in these reactors within just two seconds. This innovative system enables real-time monitoring of […]
The deluge of goodbye messages from people leaving X began shortly after Donald Trump’s election victory last week. In explaining their decision, many in the exodus cited the same thing: The huge support Elon Musk, the social media service’s owner, gave the Republican candidate during the campaign and the increasing nastiness on his site. Jody […]
A team of Rice University researchers has developed an innovative electrochemical reactor to extract lithium from natural brine solutions, offering a promising approach to address the growing demand for lithium used in rechargeable batteries. This breakthrough, published in the Proceedings of the National Academy of Sciences , holds significant potential for renewable energy storage and […]
The password manager NordPass has once again released its annual list of the world’s most popular passwords — and the lack of creativity is just a little disheartening. For the second year in a row, “123456” has been crowned the most common password. The same numbers topped the chart five out of the six times NordPass has […]
Suspected Russian hackers were caught exploiting a recently patched Windows vulnerability as a zero-day in ongoing attacks targeting Ukrainian entities. The security flaw (CVE-2024-43451) is an NTLM Hash Disclosure spoofing vulnerability reported by ClearSky security researchers, which can be exploited to steal the logged-in user’s NTLMv2 hash by forcing connections to a remote attacker-controlled server. […]
Citigroup Inc. cut its short-term outlook for copper prices by 11% as likely hikes in US trade tariffs under a Trump presidency and weaker-than-expected China stimulus would weigh on demand. “Former President Donald Trump’s election for a second term marks a clear turning point in global trade tariff policy,” analysts at Citigroup wrote in a […]
Barely nine months after the last cut, NASA’s Jet Propulsion Laboratory will again reduce its workforce. On Wednesday, the lab will lay 325 employees off, representing about 5 percent of the workforce at the California-based laboratory that leads the development of robotic space probes for NASA. “This is a message I had hoped not to […]
In iOS 18, Apple has introduced a clever new way to identify if your iPhone charging setup is running at less than optimal speeds. The new feature appears directly in Settings, making it easy to spot when you’re not getting the fastest possible charge. The Battery section displays a Slow Charger message when your iPhone detects a […]
UC Santa Barbara materials faculty members Raphaële Clément and Ram Seshadri will work with colleagues across the U.S. in one of two U.S. Department of Energy (DOE) Energy Innovation Hub teams funded by a five-year, $125 million grant, “to seed and accelerate next-generation technologies beyond today’s generation of lithium (Li)-ion batteries,” the DOE stated. The multi-institution teams, one led by Argonne […]
