A theoretical study on the ICT mechanism of zinc ion fluorescent probe based on triphenylamine.

The development of fluorescent probes for zinc ion (Zn) detection has significant importance in biological, environmental, and materials sciences. This study investigates the fluorescence enhancement mechanism of a novel triphenylamine-based probe (SHK) upon Zn coordination using density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations. The PBE0/TZVP method revealed that free SHK exhibits weak fluorescence due to intramolecular charge transfer (ICT) between the triphenylamine hydroxybenzaldehyde and 2-hydrazinyl benzothiazole moieties, characterized by a large spatial electron-hole separation (D = 6.

Interactive symbolic regression with co-design mechanism through offline reinforcement learning.

Symbolic Regression holds great potential for uncovering underlying mathematical and physical relationships from observed data. However, the vast combinatorial space of possible expressions poses significant challenges for previous online search methods and pre-trained transformer models, which mostly do not consider the integration of domain experts' prior knowledge. To address these challenges, we propose the Symbolic Q-network, an advanced interactive framework for large-scale symbolic regression.

Exogenous 24-Epibrassinolide Improves Low-Temperature Tolerance of Maize Seedlings by Influencing Sugar Signaling and Metabolism.

Low-temperature (LT) stress seriously affects the distribution, seedling survival, and grain yield of maize.

Machine learning-aided understanding of the structure-activity relationship: a case study of MoS supported metal-nonmetal pairs for the hydrogen evolution reaction.

Understanding the structure-performance relationship is crucial for designing highly active electrocatalysts, yet this remains a challenge.
