Hydrogen-Bonding-Driven Design of Organic-Inorganic Hybrid Ferroelastics with Reversible Photoisomerization.
Inorg Chem

Department of Chemistry & CICECO-Aveiro Institute of Materials, University of Aveiro, 3810-193 Aveiro, Portugal.
The development of photoresponsive ferroelastics, which couple light-induced macroscopic mechanical and microscopic domain properties, represents a frontier in materials science with profound implications for advanced functional applications. In this study, we report the rational design and synthesis of two new organic-inorganic hybrid ferroelastic crystals, (MA)(MeN)[Fe(CN)(NO)] (MA = methylammonium) () and (MA)(MeNOH)[Fe(CN)(NO)] (), using a dual-organic molecular design strategy that exploits hydrogen-bonding interactions for tailoring ferroelastic properties. Specifically, exhibits a two-step phase transition at 138 and 242 K, while the introduction of a hydroxyl group in stabilizes its ferroelastic phase to a significantly higher temperature, achieving a phase transition at 328 K, 86 K above that of .

Background: Individuals with mental health disorders face major barriers in accessing smoking cessation care, often due to the stigmas associated with mental disorders and addiction. Consequently, accessible population-based smoking cessation interventions are needed for this vulnerable group.
Objective: This secondary analysis utilized data from a 12-month randomized trial to examine whether an acceptance and commitment therapy-based app (iCanQuit) demonstrated greater efficacy, engagement, and satisfaction compared to a United States (US) Clinical Practice Guidelines-based app (QuitGuide) in helping adults with mental health disorders quit smoking.
RL-QPSO net: deep reinforcement learning-enhanced QPSO for efficient mobile robot path planning.

Introduction: Path planning in complex and dynamic environments poses a significant challenge in the field of mobile robotics. Traditional path planning methods such as genetic algorithms, Dijkstra's algorithm, and Floyd's algorithm typically rely on deterministic search strategies, which can lead to local optima and lack global search capabilities in dynamic settings. These methods have high computational costs and are not efficient for real-time applications.

Bamboo Industry Institute, Zhejiang A&F University, Hangzhou 311300, China. Electronic address:
Chitosan (CS) based sponge shows important potential applications in adsorption, filtration, sensing, etc., which often requires good deformation-recovery ability that is usually achieved under the help of silane elastomers. Herein, a simple but innovative strategy was proposed that only bamboo activated carbon (BAC) was employed as the reinforcer to construct highly elastic phosphorylated chitosan (P-CS) sponge with through-hole structure like layer-support by freeze drying.

Calcium phosphate (CaP)-based bioscaffolds are used for bone tissue regeneration because of their physical and chemical resemblance to human bone. Calcium, phosphate, sodium, potassium, magnesium, and silicon are important components of human bone. The successful biomimicking of human bone characteristics involves incorporating all the human bone elements into the scaffold material.
