An interdisciplinary team of experts in green chemistry, engineering and physics at Flinders University in Australia has developed a safer and more sustainable approach to extract and recover gold from ore and electronic waste.

Explained in the leading journal Nature Sustainability, the gold-extraction technique promises to reduce levels of toxic waste from mining and shows that high purity gold can be recovered from recycling valuable components in printed circuit boards in discarded computers.

In summary, this review provides a comprehensive picture of how low-dimensional perovskite materials could revolutionize memory devices and computing, which is expected to inspire new ideas and discussions in the near future.

Seoul National University College of Engineering announced that Professor Jong-Ho Lee's research team from the Department of Electrical and Computer Engineering has developed a groundbreaking new hardware security technology based on commercially available 3D NAND flash memory (V-NAND flash memory).

Named "Concealable Physical Unclonable Function (Concealable PUF)," this technology maintains the core advantages of conventional PUFs—unclonability and randomness—while adding a novel feature: the ability to hide the security key and reveal it only when needed. This marks the world's first implementation of such functionality on V-NAND flash memory.

The study was published online on June 3 in Nature Communications, one of the most prestigious scientific journals.
