Research Highlights

A novel AlOOH-based cement exhibits robust mechanical stability under supercritical geothermal conditions by uncovering the mechanistic role of alkali-driven dehydroxylation. Published as a cover article in ACS Materials Letters: https://pubs.acs.org/doi/full/10.1021/acsmaterialslett.4c02678

A detailed operando study on Ni-rich layered cathodes uncovers how crystallographic orientation-dependent phase separation drives capacity fade under fast charging and extended cycling. https://pubs.acs.org/doi/full/10.1021/acs.chemmater.3c00924

A synchrotron single-crystal diffraction study combined with DFT calculations reveals how metastability emerges from mechanically induced structural transitions in CsPbBr3, limiting its photovoltaic performance under real-world conditions. https://pubs.acs.org/doi/full/10.1021/acsaem.5c00303
