Chemistry Nobel Prize awarded to trio in field of metal organic frameworks
The Royal Swedish Academy of Sciences has awarded the 2025 Nobel Prize in chemistry to Susumu Kitagawa, Richard Robson and Omar M Yaghi for their work in the development of metal organic frameworks (MOF). The three scientists, who won the award on Wednesday, come from the universities of Kyoto in Japan, Melbourne in Australia and Berkeley in the United States, respectively. Such constructions can be used to harvest water from desert air, capture carbon dioxide, store toxic gases or break down traces of pharmaceuticals in the environment. "Metal organic frameworks have enormous potential, bringing previously unforeseen opportunities for custom-made materials with new functions," said Heiner Linke, chair of the Nobel Committee for Chemistry. According to Olof Ramstrom, a member of the Nobel Committee for Chemistry, the new form of molecular architecture can be compared with the handbag of the fictional Harry Potter character Hermione Granger: small on the outside but very large on the inside.
Supplementary Material for PTQD: Accurate Post-Training Quantization for Diffusion Models Y efei He
ZIP Lab, Monash University, Australia We organize our supplementary material as follows: In section A, we provide a comprehensive explanation of extending PTQD to DDIM [10]. In section B, we show the statistical analysis of quantization noise. In section D, we provide additional visualization results on ImageNet and LSUN dataset. We first perform statistical tests to verify if the residual quantization noise adheres to a Gaussian distribution. This test is based on D'Agostino and Pearson's In Figure B, we present the variance of the residual uncorrelated quantization noise.
