Summary: Hybrid exciton-polaritons are demonstrated in a structure comprising semimagnetic and nonmagnetic quantum wells coupled via the microcavity optical mode, with the emerging states acquiring magnetic properties due to the susceptibility of excitons in the magnetic quantum well. External magnetic fields enable control over the degree of hybridization, tuning of the ratio of excitonic to photonic components, and alteration of energy transfer between excitonic states in magnetic and nonmagnetic quantum wells. The possibility of hybridizing a semimagnetic exciton with an exciton in a material lacking meaningful magnetic effects holds promise for systems with strong magnetooptical properties.

Summary: Asymmetric catalysis is a powerful tool for synthesizing enantioenriched molecules. Deracemization, the direct conversion of a racemic compound to one enantiomer, is an attractive approach with high-atom efficiency. Visible-light-driven photocatalysis has recently emerged as a promising platform for deracemization, overcoming kinetic and thermodynamic challenges in chemical transformations without the need for additional stoichiometric reagents. This review systematically summarizes and discusses the advances in this area, categorizing examples based on energy transfer and single-electron transfer in photocatalysis.

Summary: Researchers have fabricated organic semiconductor microcavities containing J-aggregates of a cyanine dye with an extended optical path-length, and studied the structures using optical-reflectivity, finding a transition from normal strong coupling to decoupled photon-modes by changing the effective oscillator strength within the cavity. Both coupled and decoupled structures were compared in terms of the distribution of the confined optical field using an eight-level modified Hamiltonian.

Summary: In recent years, peroxymonosulfate (PMS)-based advanced oxidation process has gained much attention due to its efficient degradation of antibiotics. However, the challenge lies in the low efficiency of PMS activation for practical applications. A promising approach is the design of catalysts that can activate PMS through hybrid radical and non-radical pathways. In this study, a CoP@Co2P heterostructure catalyst was synthesized and showed excellent performance in tetracycline degradation.

Summary: Researchers directly observed the nuclear dynamics accompanying singlet exciton fission (SEF) in single crystal pentacene using femtosecond electron diffraction. The data revealed coherent atomic motions at 1 THz, incoherent motions, and an anisotropic lattice distortion representing the polaronic character of the triplet excitons.Long-range motions were found to play a decisive part in the electronic decoupling of the electronically correlated triplet pairs, shedding light on the ultrafast occurrence of SEF.

Summary: Layered perovskite quantum wells show potential for optoelectronic devices, with gradients in quantum well concentrations promoting funneling of electronic excitations and charge carriers. However, experiments suggest that charge carrier funneling processes do not facilitate long-range transport due to trapping, with bulklike phases of films transporting carriers without involvement of the smallest quantum wells.

Summary: In this study, it was discovered that trace Mn(II) can effectively catalyze the oxidation of organic contaminants by periodate (PI), outperforming the representative TRSs-dominated AOPs. The formation of colloidal MnO2 was found to be responsible for the enhanced treatment performance, serving as both oxidant and catalyst. The study elucidated the roles of Mn(II) and colloidal MnO2 in PI-mediated contaminant degradation, highlighting the superiority of trace catalyst-assisted process without TRSs involvement in maximizing oxidation efficiency and avoiding undesired side reactions.

Summary: In this study, an electrocatalytic ozonation (ECO) system called ECO-Fe-cathode was developed, which achieved higher degradation efficiency of pollutants compared to the ECO-Fe-anode system. The primary reactive oxygen species (ROS) in the ECO-Fe-cathode system was found to be singlet oxygen (O-1(2)), while hydroxyl radicals ((OH)-O-center dot) were the primary ROS in the ECO-Fe-anode system. This research provides a fundamental breakthrough in designing efficient and harmless ECO systems for wastewater treatment.

Summary: A Co3O4-activated chlorite (Co3O4/chlorite) process was developed for efficient oxidation of organic contaminants. Proton-coupled electron transfer and oxygen atom transfer were involved in Co(IV) formation and ClO2 generation in the process. The contribution of Co(IV) and ClO2 to contaminant degradation varied with pH changes, and ClO2 was transformed into non-toxic Cl- after the reaction, reducing environmental risks.

Summary: Tungsten oxide nanowires (WO3_x) with rich oxygen vacancies (OVs) were prepared through a hydrothermal method, demonstrating high adsorption capacity and photocatalytic activity. The WO3_x successfully removed 95.1% of U(VI) at pH 5, with 79.9% being transformed to U(IV) for reductive immobilization. Compared to conventional WO3, WO3_x exhibited narrower band gap energy, higher charge carrier separation, and faster transfer rates, attributed to its construction of oxygen vacancies.

Summary: Electrochemical disinfection (ED) effectively removes antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in wastewater treatment. This study investigated the disinfection mechanism at a microcosmic level using different strains of Escherichia coli (E. coli) with varying antibiotic resistant phenotypes. Findings showed that bacteria with multiple antibiotic resistance had higher viability during disinfection compared to those with fewer resistance. Notably, antibiotic-resistant phenotypes remained largely unchanged during disinfection, while genotypes closely responded to E. coli's resistance. β-lactamase resistance genes played a significant role in cross-resistance between antibiotics and electrochemical oxidation by strengthening the cell wall and membrane. This study provides important insights into and control of antibiotic resistance with advanced oxidation processes.

Summary: Interfacial modulation of catalysts can enhance catalytic activity, and this study focuses on revealing the mechanism of reactive species production at different interfaces. Zr-S-4 active sites were successfully constructed on ZnIn2S4 nanosheets, effectively modulating the reaction interface and band structure, which significantly boosted the photocatalytic activity. The modified catalyst exhibited a 3-fold increase in the kinetic rate constant for photocatalytic degradation compared with the pristine ZnIn2S4, and the degradation pathway of TC was altered due to the regulation of reactive species.

Summary: Rationally regulating reaction mechanisms in Fenton-like reactions by tuning the properties of catalysts is challenging but significant. Various catalysts with different active center sizes were synthesized to realize the switching of reaction mechanisms and pollutant degradation routes in peroxymonosulfate (PMS) activation systems. The transformation of reaction mechanism from radical oxidation to nonradical oxidation was observed with the decrease of active center size. The toxicity tests indicated that the conversion from non-selective to selective oxidation resulted in lower toxicity of effluent after reaction, reducing environmental risks.

Summary: The continuous presence of organic pollutants in industrial wastewater poses a significant threat to human health, necessitating urgent and effective treatment. Photocatalytic degradation technology, specifically the use of TiO2 photocatalysts, provides a viable solution for the removal of organic pollutants. However, the limited absorption of visible light by TiO2 hinders its full utilization. To address this issue, the study developed an environmentally friendly synthesis of Ag-coated on micro-wrinkled TiO2-based catalysts, enabling extended absorption of visible light. The synthesized C/F-Ag-TiO2 composite exhibited a significantly lower band gap energy and achieved a remarkable degradation rate under visible light, making it a promising candidate for highly efficient environmental remediation.
