In this work, we investigated the response of the metal-organic framework MIL-125-NH to ball-milling. Both localised and bulk analyses revealed prolongued ball-milling results in a complete loss of long-range structural order. Investigation of this disorder revealed partial retention of the local bonding of the secondary building unit, suggesting structure collapse progressed primarily through metal-linker bond breakage. We explored the photocatalytic performance of the materials, and examined the materials' band gap using UV-Vis reflectance spectroscopy.

Importance: Epidemiological studies suggest that lifestyle factors are associated with risk of dementia. However, few studies have examined the association of diet and waist to hip ratio (WHR) with hippocampus connectivity and cognitive health.
Objective: To ascertain how longitudinal changes in diet quality and WHR during midlife are associated with hippocampal connectivity and cognitive function in later life.

In situ high-pressure single-crystal X-ray diffraction and Raman spectroscopy analyses were performed on a natural bismutotantalite with an α-BiTaO structure. The results indicate that α-BiTaO transforms into an orthorhombic phase (HP γ-BiTaO), likely through an intermediate orthorhombic phase (HP β-BiTaO). The transition pressures are 11.

A key challenge for sodium-ion batteries (SIBs) lies in identifying suitable host materials capable of accommodating large Na ions while addressing sluggish chemical kinetics. The unique interfacial effects of heterogeneous structures have emerged as a critical factor in accelerating charge transfer and enhancing reaction kinetics. Herein, MoSe/BiSe composites integrated with N-doped carbon nanosheets are synthesized, which spontaneously self-assemble into flower-like microspheres (MoSe/BiSe@N-C).

Co-crystal engineering is of interest for many applications in pharmaceutical, chemistry and material fields, but rational design of co-crystals is still challenging. Although artificial intelligence has brought major changes in the decision-making process for materials design, yet limitations in generalization and mechanistic understanding remain. Herein, we sought to improve prediction of co-crystal by combining mechanistic thermodynamic modeling with machine learning.

Salvia miltiorrhiza (Danshen in Chinese) is a traditional medicinal plant with an extensive range of cardiocerebrovascular protective effects widely used in China and other Asian countries. Danshensu (DSS) is the most important water-soluble component of Danshen and has significant antioxidant, anti-inflammatory, antiplatelet aggregation, antitumor, and other pharmacological activities. However, DSS has poor fat solubility and is unstable due to its o-phenol hydroxyl and α-hydroxy carboxylic acids.
