Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed an AI semiconductor device that adjusts its response characteristics to match how quickly data changes. KAIST said the team developed a programmable dynamic memtransistor and an integrated array by combining a charge storage layer and an electron trapping layer in one transistor. Experiments showed recovery time could be tuned about fivefold and frequency characteristics by more than 10-fold, cutting prediction errors by up to 40-fold in tests.

LG Energy Solution said it developed a high-capacity battery using sulfur as a cathode material by applying all-solid-state battery technology. The company said the approach blocks polysulfide dissolution seen in liquid electrolytes, securing about 1,500 mAh/g capacity and stable cycle life. It said the performance was demonstrated in both coin cells and pouch-type cells. The work was conducted with a University of Chicago research team and published in Nature Communications.
