Summary: Porous Bi2O3-Bi2S3 composite sheets were synthesized through a combination of chemical bath deposition and hydrothermal reaction, and the Na2S precursor concentration was varied to investigate the impact on the structure and vulcanization degree of the composites. The use of suitable sulfide precursor concentration during the hydrothermal reaction enabled the control of the etching rate of the Bi2O3 template and the regrowth rate of Bi2S3 crystallites, resulting in the formation of porous Bi2O3-Bi2S3 sheets. The presence of Bi2S3 crystallites and the porous structure in the composites contributed to improved visible-light absorption and separation efficiency of photogenerated charge carriers, making them highly promising for photoactive device applications.

Summary: A modified sol-gel process using Pluronic F-127 as the surfactant successfully synthesized bismuth oxide (Bi2O3). By incorporating mesoporous Bi2S3 nanoparticles onto the surface of Bi2O3, heterojunctions that enhance charge transfer and visible light absorption were formed. The content of Bi2S3 determined the effectiveness of the heterojunctions, with 3.0 wt% achieving the best photocatalytic activity for tetracycline degradation. The nanocomposite showed notable reusability and a boosted photocatalytic efficiency through a Z-scheme mechanism.

Summary: Graphitic carbon-doped alpha-Bi2O3/beta-Bi2O3/Bi5O7I ternary heterojunction photocatalysts were successfully synthesized via a simple and low-cost method using urea, malonic acid, and BiOIO3. The photocatalytic activity of the catalysts was evaluated by the degradation of Bisphenol A (BPA) under simulated sunlight irradiation. The graphitic carbon-doped alpha-Bi2O3/beta-Bi2O3/Bi5O7I photocatalysts exhibited significantly higher reaction rate constants compared to other catalysts, thanks to the synergistic effect of the heterojunction between different components and the efficient electron transfer efficiency of graphitic carbon. A dual S -scheme heterojunction mechanism was proposed to explain the excellent redox properties of the composites.

Summary: Mesoporous Bi2S3/ZrO2 nanocomposites were synthesized using Pluronic (F-68) as a surfactant by sol-gel process and applied for thiophene oxidation under visible illumination. Bi2S3 NPs were distributed on mesoporous ZrO2 and exhibited a greater separation rate of charge carriers and extended light response compared to pure ZrO2. The optimized 15% Bi2S3/ZrO2 showed the highest photocatalytic efficiency (100%) within 105 min of visible light illumination. The photocatalytic efficiency of Bi2S3/ZrO2 nanocomposites was significantly higher than that of pure ZrO2 NPs, and the rate constant of the 15% Bi2S3/ZrO2 photocatalyst was improved 5.25 times larger than that of pure ZrO2 NPs. The improved photocatalytic ability of Bi2S3/ZrO2 nanocomposites was attributed to the formation of heterojunction Bi2S3/ZrO2, incorporation of Bi2S3 into ZrO2 and utilization of visible light in wide wavelengths.

Summary: This study presents a visible-light-driven organic-inorganic S-scheme heterostructure photocatalyst with excellent performance in removing antibiotics from wastewater. By anchoring TCPP on the surface of Bi12O17Cl2, the S-scheme junction between TCPP and Bi12O17Cl2 was created, enhancing the visible-light response and accelerating the disintegration and conservation of photo-carriers. The resulting TCPP/Bi12O17Cl2 showed significantly improved photocatalytic activity and stability compared to Bi12O17Cl2. Through scavenging tests, LC-MS analysis, and toxicity calculation, the reactive radicals, degradation pathway, and eco-toxicity were elucidated. This research demonstrates the potential practicality of porphyrin-based S-scheme heterojunction photocatalysts for efficient antibiotic removal.

Summary: The spikelet number per spike (SNS) and spike length (SL) are important traits for increasing wheat yields. Photoperiod-1 (Ppd-1) plays a crucial role in regulating inflorescence structure and paired spikelet development. Through genetic marker analysis, eight PPD1 combination homoeologs were identified in 170 recombinant inbred lines (RILs) derived from a cross between synthetic hexaploid wheat (SHW-L1) and a commercial cultivar (Chuanmai 32). The results showed significant positive correlations between days to heading (DTH) and both SNS and SL, and also between SL and SNS. The photoperiod-sensitive ppd-D1b alleles had the largest effect on delaying heading, indicating their potential to increase wheat yields.

Summary: Solar-driven elimination of refractory contaminants is an ideal approach for environmental remediation. However, the photocatalytic performance of photocatalysts is limited by insufficient reactive sites and fast recombination of electrons and holes. In this study, a novel metal-organic framework-based heterostructure of MIL-101(Fe)/Bi2WO6 was synthesized, which exhibited significantly enhanced photoactivity for Cr(VI) reduction and tetracycline hydrochloride oxidation compared to individual Bi2WO6 and MIL-101(Fe). The improved catalytic performance can be attributed to the enlarged surface area and pollutant adsorption facilitated by MIL-101(Fe), as well as the efficient photo-carrier transport mechanism supported by oxygen vacancies.

Summary: The interaction between PD-L1 and PD-1 plays a critical role in limiting the function of effector T cells against cancer cells. Therapies that block this pathway have been approved for multiple tumor indications. This report presents the pharmacology of an orally-available small molecule PD-L1 inhibitor, CCX559, for cancer immunotherapy. CCX559 effectively inhibits PD-L1 binding to PD-1 and CD80, and enhances activation of primary human T cells. Preclinical studies in murine tumor models demonstrate anti-tumor activity comparable to an anti-human PD-L1 antibody. These findings support the clinical development of CCX559 for solid tumors.

Summary: A novel Ag/MIL-68(In)-NH2/Bi4O7 plasmonic heterojunction was successfully prepared and showed the most efficient photocatalytic performance in the degradation of amoxicillin, with 3.7 and 3.2 times higher activity than Bi4O7 and MIL-68(In)-NH2, respectively. The superior performance was attributed to the large surface area and localized surface plasmon resonance (LSPR) effect, which provided more active sites and enhanced visible light absorption. The degradation pathway of amoxicillin was also investigated using Gaussian software calculation and liquid chromatography-mass spectrometry (LC-MS) analysis. Lastly, characterizations and simulations were conducted to explain the S-scheme photocatalytic mechanism.

Summary: Using crustacean shell wastes to produce chitin/chitosan-based biosorbents has attracted attention due to its potential for waste recycling and environmental remediation. A novel EDTA-grafted chitin (ECH) was prepared using an environmentally-friendly one-step procedure with Portunus trituberculata shells. The ECH showed excellent adsorption efficiency and reusability for Cu(II) adsorption, with a maximum removal rate of 99.4% and an adsorption capacity of 223.70 mg g(-1). The adsorption mechanisms were attributed to the formation of EDTA-chitin-Cu complex. These findings contribute to the development of more facile and green chitin-based biosorbents from crustacean shell wastes and their application in environmental restoration.

Summary: In this study, a visible-light-driven one-dimensional nanostick silver/silver sulfide (Ag/Ag2S) photocatalyst was prepared by combining it with a two-dimensional nanosheet reduced graphene oxide (RGO) intersected by hollow structure (h-RGO) at room temperature. The density of Ag on the surface of Ag2S was controlled by the concentration of sodium borohydride, and silicon dioxide nanospheres were used as templates in the preparation of h-RGO. The ternary plasmonic Ag/Ag2S/h-RGO photocatalysts showed superior photocatalytic performance for the degradation of naphthalene and 1-naphthol under visible light. The enhancement was attributed to the localized surface plasmon resonance of Ag, the heterojunction formed between Ag/Ag2S and RGO, and the unique characteristics of h-RGO. The study also examined the degradation mechanisms, potential pathways, and toxicity of the generated intermediates for photodegradation. In addition to expanding effective plasmonic photocatalysts with novel structures, this research is beneficial for alleviating environmental crises to a certain extent.

The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
