GOHBA: Improved Honey Badger Algorithm for Global Optimization.

Aiming at the problem that the honey badger algorithm easily falls into local convergence, insufficient global search ability, and low convergence speed, this paper proposes a global optimization honey badger algorithm (Global Optimization HBA) (GOHBA), which improves the search ability of the population, with better ability to jump out of the local optimum, faster convergence speed, and better stability. The introduction of Tent chaotic mapping initialization enhances the population diversity and initializes the population quality of the HBA. Replacing the density factor enhances the search range of the algorithm in the entire solution space and avoids premature convergence to a local optimum.

High-Density Donor-Acceptor Pair Mediated Carrier Transport Dynamics for Hydrogen Production Performance Promotion Based on Nonstoichiometric Quantum Dots.

Ternary I-III-VI semiconductors are useful light-capture materials, but the presence of a special donor-acceptor pair complicates the dynamics of carriers in the photocatalytic process, and the combined effect of multiple types of defects makes it difficult to study the single type of defect on carrier dynamics. Here, excess inorganic S ligand is used to passivate the surface defects of the nonstoichiometric ratio Ag-In-Zn-S quantum dots (QDs), which enables the systematic investigation of the effects of high-density donor-acceptor pairs on the carrier separation and transfer path during photocatalysis. The results show that the donor-acceptor pair defects in quantum dots can effectively separate the carriers because the defects generated by the donor or acceptor can effectively "store" the carriers at the fixed energy level and provide an additional path for the transfer of the carriers.

Boosting the oxygen reduction activity on metal surfaces by fine-tuning interfacial water with midinfrared stimulation.

Heterogeneous catalysis at the metal surface generally involves the transport of molecules through the interfacial water layer to access the surface, which is a rate-determining step at the nanoscale. In this study, taking the oxygen reduction reaction on a metal electrode in aqueous solution as an example, using accurate molecular dynamic simulations, we propose a novel long-range regulation strategy in which midinfrared stimulation (MIRS) with a frequency of approximately 1,000 cm is applied to nonthermally induce the structural transition of interfacial water from an ordered to disordered state, facilitating the access of oxygen molecules to metal surfaces at room temperature and increasing the oxygen reduction activity 50-fold. Impressively, the theoretical prediction is confirmed by the experimental observation of a significant discharge voltage increase in zinc-air batteries under MIRS.

Solvent-Regulated Cyclization of Arylidene Isoxazolones with Amidines for Regiodivergent Synthesis of 4- and 5-Acylimidazoles.

-Iodosuccinimide-promoted cascade reactions of arylidene isoxazolones with amidines in -xylene were accomplished, affording 5-acylimidazoles in good to excellent yields.

The study involves the modification of a non-conventional starch isolated from the under-utilized variety of Chinese water chestnut (CWC (Eleocharis tuberosa) and integrating it to fabricate stabilized and curcumin-enriched Pickering emulsions with enhanced bioavailability, thermal stability, and retention of encapsulated curcumin. A time-efficient, semi-dried esterification method was used to prepare modified amphiphilic starches using 3, 6, or 9 % (w/v) octenyl succinic anhydride (OSA) and characterized through degree of substitution (DS), contact angle, particle size, scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and in-vitro digestibility. Moreover, Pickering emulsions were formulated using CWCS-OSA at 3 %, 6 %, or 9 % concentrations to serve as a carrier for curcumin to improve its water solubility and storage stability.

A high-contrast NIR excitation probe for monitoring Cu in the endoplasmic reticulum for synergistic cuproptosis and ferroptosis anticancer therapy.

BHCO-Cu (Cu2BC) can lead to DLAT protein aggregation, triggering cuproptosis.
