Article Abstract
A pyrene-substituted acylhydrazone (PyAc) crystal undergoes a water-driven transition from elasticity to thermoplastic bending. The hydrated crystal remains two-dimensional (2D) elastic until heating, after which it becomes brittle and bent upon dehydration. While the hydrated crystal is non-photoresponsive, the anhydrous form exhibits photomechanical bending due to favorable - photoisomerization. These distinct properties, governed by solvent channels, molecular packing, and non-covalent interactions, demonstrate PyAc's potential for smart actuators and photoswitchable devices.

In recent years, amino acids have garnered extensive attention as environmentally friendly, small-dose additives for modulating hydrate formation and aggregation behavior. Amino acids, due to their amphiphilic nature, can adsorb at the gas-liquid interface and on hydrate crystal surfaces, thereby modifying interfacial properties and influencing crystal growth patterns. In our measurements, the amino acids displayed a concentration-dependent "double effect".

Solid-state electrolytes (SSEs) are being extensively researched as replacements for liquid electrolytes in future batteries. Despite significant advancements, there are still challenges in using SSEs, particularly in extreme conditions. This study presents a hydrated metal-organic ionic cocrystal (HMIC) solid-state ion conductor with a solvent-assisted ion transport mechanism suitable for extreme operating conditions.

We report the hydrothermal syntheses and structural and spectroscopic characterization of two new uranium oxide hydrate frameworks (UOHFs) with either Pr or Nd ions, Pr(HO)[(UO)UO(OH)] () or Nd(HO)[(UO)UO(OH)] (). Both UOHFs crystallize in the orthorhombic 222 space group and display needle crystal morphologies. Their crystal structures are composed of β-UO-type layers connected by double uranium polyhedra to form the frameworks, with disordered Pr/Nd ions within the framework channels, as revealed by synchrotron single-crystal XRD.

Hydrated magnesium sulfates (MgSO·HO) are known to form multiple hydration states ( = 0-11) and are essential in planetary science and thermochemical energy storage. Despite their significance in detecting extraterrestrial water reservoirs or in mineral (de)hydration cycles, it is still necessary to understand how the structure-property relationships of these materials evolve at different hydration levels when pressure is applied. Through a systematic first-principles computational investigation, we elucidate the key structural factors governing the densification mechanism under hydrostatic pressure of MgSO·HO crystals.

In order to promote the development and application of low-carbon cement varieties and the recycling of industrial solid waste, this study used iron tailings and fluorogypsum to prepare iron-rich belite-sulfoaluminate cement (I-BCSA). The suitable conditions for the preparation of I-BCSA in this system were with an excessive addition of 6 wt% of SO in the raw meal, at a calcination temperature of 1250 °C for 1.5 h, and an added-gypsum content of 15 wt%.
