Summary: In this study, a visible light-responsive Sn2+ and N co-doped TiO2 photocatalyst was prepared using a facile one-pot hydrothermal method. The co-doped catalyst showed extended absorption edge to visible light region and higher hydrogen production performance compared to singly doped TiO2. The synergistic effect of O 2p-N 2p and O 2p-Sn 5s hybridization is the main reason for the improved catalytic activity.

Summary: This article details the development of a photochemical reaction involving cyclopropylimines and substituted alkenes, which undergo a [3+2] cycloaddition to form aminocyclopentane derivatives. The use of a Schiff base enables a masked N-centered radical approach, which is activated upon excitation with visible light. The cycloaddition products can be directly converted to N-functionalized aminocyclopentanes through solvolysis and N-acylation. The photochemical component of this reaction has been demonstrated to be feasible in continuous flow.

Summary: β-Bi2O3/Bi2O2CO3 composites synthesized through solvothermal method exhibited high photocatalytic activity for the degradation of bisphenol A (BPA). Both solvothermal and calcination temperatures significantly affected the photocatalytic performance of the composites, with optimal activity achieved at a solvothermal temperature of 180 degrees C and a calcination temperature of 300 degrees C. The composites had a rose-like structure and wide absorption range, and the photocatalytic activity was attributed to factors such as specific surface area and band gap. The phase transition from Bi2O2CO3 to β-Bi2O3 was also found to contribute to the high photocatalytic activity.

Summary: Exposure to pollutants can cause damage to the eyes of aquatic organisms. Zebrafish is a commonly used model to study ocular toxicity and has shown morphological changes, retinal damage, and abnormalities in visual signal processes. The underlying mechanisms involve thyroid hormone signaling, retinoic acid signaling, and retinal glucose metabolism. This review discusses the phenotypes and signaling pathways associated with ocular toxicity from contaminants, detection methods, and a predictive model for potential ocular toxicity.

Summary: During the 2015-2016 Chinese Antarctic Research Expedition, a study was conducted on Particulate-bound mercury (PBM) in the boundary layer. The study found a significant latitudinal gradient in PBM, with higher levels over the Northern Hemisphere influenced by both continental and oceanic sources. Over the Southern Ocean, PBM levels were extremely low, while elevated PBM was observed across the Antarctic Ice Sheet, particularly at Dome A. The study also revealed the role of inland Antarctic snow in influencing atmospheric PBM concentrations over the Antarctic coastal seas.

Summary: This study demonstrates the significant role of cationic configuration in nonlinear optical (NLO) properties, achieving a remarkable enhancement in second-harmonic generation (SHG) by continuously tuning the Cu displacement under pressure. The in situ high-pressure structural characterization shows that Cu cations move from the van der Waals edge to the cages of S6 octahedra and form highly distorted [CuS6] octahedra. The contributions of cationic displacement on octahedral distortion and interband dipole moments are quantitatively demonstrated, which dominate optical nonlinearity and determine the enhanced SHG.

Summary: Succinate, an intermediate of the TCA cycle, is crucial in mitochondrial metabolism, energy production, and is also considered a signaling molecule in metabolism and hepatic diseases. Its downstream signaling pathway through GPR91 leads to various intracellular responses, including succinylation, ROS production, HIF-1 alpha stabilization, and significant impact in cellular metabolism due to its role in the TCA cycle. Understanding the signaling mechanisms of succinate in hepatic fibrosis, metabolic reprogramming, inflammatory or immune responses, and carcinogenesis is of great interest. This review aims to provide the current understanding of succinate in mediating metabolism, inflammatory and immune responses in liver diseases, with the aim of establishing a molecular basis for therapeutic strategies.

Summary: We investigate the behavior of solutions to a scalar Delay Differential Equation (DDE) with periodic switching between two constant values. This equation naturally arises in structured vector populations involved in the spread of various vector-borne diseases in a periodically changing environment. We examine the influence of two different time lags and the switching time on the existence and patterns of periodic solutions, with a specific focus on multi-cycles within the prime period.
