Researchers unlock 'silicate magic' for safer, cheaper, and more efficient batteries. Xiaowei Teng, the James H. Manning Professor in Chemical Engineering at WPI, is leading a team to explore new battery technologies for grid energy storage. The team's recent results, published in ChemSusChem, suggest that iron, when treated with the electrolyte additive silicate, could create a high-performance alkaline battery anode. The second most abundant metal in the Earth's crust after aluminum, iron is far more sustainable than nickel and cobalt. The United States alone recycles approximately over 40 million metric tons of iron and steel from scrap each year - https://lnkd.in/g9WDjbTP #batteries #batterytechnology #renewables #gridstorage

Magnetic octupoles overcome problems with antiferromagnets. Physicists at RIKEN have demonstrated how ultrafast, low-power-consumption memory devices could be realized by replacing conventional magnetic materials with novel ones - https://lnkd.in/g3x9WBB2

Light-responsive material shows promise for energy-efficient supercomputing. Researchers have revealed an adaptive response with a ferroelectric device, which responds to light pulses in a way that resembles the plasticity of neural networks. This behavior could find application in energy-efficient microelectronics. Ferroelectric material adapts to light stimuli by reorganizing atomic connectivity on the nanoscale - https://lnkd.in/gUTtUDHp

Western Digital launches 32TB hard drive in SATA and SAS flavors — Ultrastar DC HC690 delivers sequential performance up to 257 MiB/s. Thanks to ePMR, which WD has used since 2020 to improve HDD capacity, and the storage company’s much newer UltraSMR technology, WD introduced an 11-disk design for the 32TB Ultrastar DC HC690. WD’s previous champion, the Ultrastar DC HC680, had 28TB of storage thanks to a 10-disk design and was the company’s first drive to use UltraSMR tech - https://lnkd.in/gkPE-ktP

9,380x Faster Than 5G: Scientists Set New Wireless Transmission Speed Record. UCL researchers set a new wireless transmission record, achieving speeds of 938 Gb/s over a frequency range of 5-150 GHz, which is up to 9,380 times faster than average UK 5G speeds. This breakthrough, combining radio and optical technologies, promises faster and more reliable wireless communication within the next few years - https://lnkd.in/guBDcWaq

Next-gen EV battery promises 186 miles with a 5-minute charge. Battery tech firm ProLogium has taken the wraps off its 100% silicon composite anode battery. Highlighting its potential for use in EVs at the ongoing Paris Motor Show, the Taiwanese company claimed a major leap in energy density and charging efficiency, promising 186 miles (300 km) of range from a five-minute charge - https://lnkd.in/g6ZUs9TC #batteries #batterytechnology

Engineers set new record on how fast data can be sent wirelessly. The team successfully sent data over the air at a speed of 938 Gigabits per second (Gb/s) over a record frequency range of 5–150 Gigahertz (GHz). To address the current limitations of wireless technology, researchers from UCL developed a novel approach that combines advanced electronics, which performs well in the 5–50 GHz range, and a technology called photonics that uses light to generate radio information, which performs well in the 50–150GHz range. The team generated high-quality signals by combining electronic digital-to-analog signal generators with light-based radio signal generators, allowing data to be transmitted across a wide range of frequencies from 5–150 GHz - https://lnkd.in/g2K2GdmK #6G
