AI Summary (NQ-processed)
Space Seed Holdings Co., Ltd. and a research group led by Professor Yoshihisa Mori of Okayama University of Science have jointly developed a new type of spark plasma sintering (SPS) device capable of stably generating ultra-high pressures exceeding 10 GPa. This device overcomes the conventional challenges of extremely small sample sizes and non-uniform pressure/temperature distributions, demonstrating the ability to sinter millimeter-scale samples under uniform pressure.
