A Tianjin University team led by Professor Hu Wenbin reported a “transient assembly” strategy using millisecond-scale periodic thermal pulses to synthesize and precisely control core–shell platinum-group metal catalysts, enabling atom-level precision and ultra-fast production. The authors say the method opens a new technical pathway for platinum-group catalyst manufacturing. Results were published online in Science on July 10 (Beijing time). Platinum-group catalysts are core materials for modern

Samsung Electronics’ System LSI division is developing a generative-AI accelerator for PCs codenamed GAIA and has supplied prototype samples to major OEMs including Lenovo and HP for performance validation, industry sources said. GAIA is built on a 4nm process and positioned as a storage‑centric AI accelerator that places compute close to memory; Samsung is also advancing integration with next‑generation DRAM processor-in-memory (PIM) technology that can execute operations on stored data. Unlike GPU-based accelerators used mainly for training and inference, GAIA is optimized for NPU architectures and targeted at generative AI tasks on the PC; mass production could begin as early as next year, the sources added.
