From texting on a smart phone to ordering train tickets at a kiosk, touch screens are ubiquitous and, in most cases, relatively reliable. But for people who are blind or visually impaired and use electronic braille devices, the technology can be vulnerable to the elements, easily broken or clogged by dirt, and difficult to repair.

Researchers from the Institute of Solid State Physics at the Hefei Institutes of Physical Science, Chinese Academy of Sciences, together with the Shenzhen International Graduate School of Tsinghua University and Suzhou University of Technology, have successfully developed a natural electron donor–assisted healing and targeted surface reconstruction strategy that enables the direct regeneration of degraded lithium iron phosphate (LiFePO ) cathode materials from retired power batteries.

1 week ago Direct grid connection technology provides fast charging solution for electric vehicles

With the surging popularity for electric vehicles (EVs), rapid charging is a challenge as it requires power delivery exceeding 1 MW (which can power about 1,000 homes). Conventional charging stations rely on bulky line frequency transformers (LFTs), which are expensive due to extensive use of copper and iron. These stations also have multiple conversion stages involving stepping up or down current, or converting AC to DC and vice versa. This can greatly increase cost and reduce efficiency.
