Mechanochemical Synthesis of Type III Porous Liquids from Solid Precursors for the Removal and Conversion of Waste CO from CH.

Porous liquids (PLs) have emerged as a promising class of flow porous materials, offering distinctive benefits for sustainable separation processes coupled with catalytic transformations in the chemical industry. Despite their potential, challenges remain in the realms of synthesis complexity, stability, and the strategic engineering of separation and catalytic sites. In this study, a scalable mechanochemical synthetic approach is reported to fabricate Type III PLs from solid precursors with high stability.

Forward‒ and Retro‒Vapofluorochromism of Sponge‒Like Macrocycle Crystals.

Achieving dynamic multicolor emission through solid-state molecular motion is of significant importance for advancing applications in organic solid-state luminescent materials. Herein, we report macrocycle crystals with unique forward‒ and retro‒vapofluorochromic behavior, which is realized by reversible amine vapor uptake and amine‒"squeeze" induced guest release. The forward‒vapofluorochromism occurs when aliphatic amines penetrate guest-free macrocycle crystals to form host‒guest complex crystals.

Machine-learning based prediction of appendicitis for patients presenting with acute abdominal pain at the emergency department.

Background: Acute abdominal pain (AAP) constitutes 5-10% of all emergency department (ED) visits, with appendicitis being a prevalent AAP etiology often necessitating surgical intervention. The variability in AAP symptoms and causes, combined with the challenge of identifying appendicitis, complicate timely intervention. To estimate the risk of appendicitis, scoring systems such as the Alvarado score have been developed.

Molecular-Squeeze Triggers Guest Desorption from Sponge-Like Macrocycle Crystals.

Desorption in conventional porous sorbents often employ external forces including inert gas blowing, heating, vacuum treatment to trigger guest release. We here report an unprecedented molecular-squeeze triggered guest release behavior from sponge-like macrocycle crystals. The crystals function as typical sponge to include guest molecules within their microscopic voids that are adaptively formed, thus acting as adsorbents for toluene/pyridine separations.

Astragaloside IV plays a neuroprotective role by promoting PPARγ in cerebral ischemia-reperfusion rats.

Background: Cerebral ischemia-reperfusion injury (CIRI) usually occurs during the treatment phase of ischemic disease, which is closely related to high morbidity and mortality. Promoting neurogenesis and synaptic plasticity are effective neural recovery strategies for CIRI. Astragaloside IV (AS-IV) has been shown to play a neuroprotective role in some neurological diseases.
