Phenothiazine-Functionalized Triazine-Based Covalent Organic Frameworks for Efficient Photocatalytic Organic Synthesis

Abstract In this work, we present a donor–acceptor molecular engineering strategy in which three electron-donating moieties including benzene, triphenylamine, and phenothiazine are condensed with electron-deficient triazine monomers via Schiff-base reaction to furnish three cryst...

A Hollow Spherical Hydrotalcite-Based Catalyst for One-Step Ethoxylation of Butyl Acetate to Oligo-Ethylene Glycol Butyl Ether Acetates

Abstract A novel hollow spherical hydrotalcite-based catalyst was developed for the direct ethoxylation of butyl acetate (BAC) to synthesize oligo-ethylene glycol butyl ether acetates (oligo-EBACs). This catalyst, which retains the intrinsic structural characteristics of hydrotal...

The association between education level, widowhood, and depression among elderly Chinese after controlling for demographic, health, and behavioral variables

With the rapid advancement of China’s aging population, the mental health problems of the elderly, especially depression, have become an important concern in the field of public health. However, research on the combined effect of education level and widowhood on depression is sti...

Influence of Fe2O3 addition on the phase equilibrium for CaO-SiO2-TiO2 system at 1300 °C in air

Optimizing the Selective Crystallization and Phase Separation (SCPS) process is essential for improving the resource utilization of titanium-bearing blast furnace slag. However, the influence of Fe 2 O 3 addition on the phase equilibria of the CaO-SiO 2 -TiO 2 system remains insu...

RGB-D Image Encryption Using a Hyperchaotic System and Quaternion Gyrator Transform

An RGB-D image encryption scheme is presented by combining a newly constructed 4D-ICTM hyperchaotic system with a reformulated quaternion gyrator transform (QGT). The proposed 4D-ICTM dynamics arise from the nonlinear combination of the ICMIC and Chebyshev maps with the tanh func...

A Comparative Study of Lexical Inferencing During Text Reading: Evidence from Chinese–English–Japanese Trilinguals

Lexical inferencing (LIF) draws on multiple knowledge sources (KSs), but little is known about how the same multilingual readers report using these sources across different reading tasks. This exploratory study examined 31 Chinese–English–Japanese trilinguals who completed think-...

Prioritizing environmental anxieties and mitigation strategies across eco-anxiety, climate, health, economic, and social domains

This study assesses environmental anxieties and prioritizes strategies to address them using an integrated expert-based multi-criteria framework. The Analytic Hierarchy Process (AHP) and Fuzzy TOPSIS are combined to identify, weight, and rank sub-anxieties across five domains: ec...

cIGW-SC: an intelligent chaotic hybrid grey wolf and sine cosine optimizer for complex engineering design problems

For intelligent systems designed to solve complex engineering design problems, premature convergence and the imbalance between exploration and exploitation remain key challenges for high-dimensional, multimodal, and composite problems. Existing approaches, including the Grey Wolf...

All electrical sub-nanosecond field-free switching of perpendicular magnetization with high magnetic field immunity

Spin-orbit torque magnetic random-access memory is a promising next-generation non-volatile memory technology featuring low power consumption, rapid operation, and high endurance. Conventional spin-orbit torque-induced deterministic perpendicular magnetization switching, however,...

Design of a deep learning-driven multidimensional evaluation model for youth training system performance assessment

In this paper, a deep learning driven multidimensional evaluation framework is proposed to evaluate the performance of Youth Training System (YTS). In order to reduce the subjectivity of manual scoring and static weight, the framework organizes resources organization, training ex...
