Summary: By using Bi2MoO6 hollow spheres as precursors, NaOH as etchant, and atmospheric CO2 as carbon source, a granular-polyhedral Ag2O-Ag2CO3/lamellar Bi2O2CO3-Bi2MoO6 spherical heterojunction material with full-spectrum photocatalytic properties was obtained through a one-step in-situ precipitation approach. The material exhibited enhanced photocatalytic activities for the degradation of methylene blue and antibiotics under visible light, attributed to increased light utilization, surface active sites, and effective heterojunction formation.

Summary: Tetracycline is one of the most widely used antibiotics in human therapy, veterinary applications, and agricultural activities. Its consumption is expected to increase by over 30% by 2030. This review focuses on the recent advancements in photocatalytic degradation of tetracycline using graphitic carbon nitride-based photocatalysts, which offer higher visible light activity, low cost, and non-toxicity. The properties, worldwide consumption, occurrence, and environmental impacts of tetracycline are comprehensively discussed. The occurrence of tetracycline in various water matrices has been confirmed, with a maximum concentration of 54 μg/L. Among different graphitic carbon nitride-based materials, heterojunctions have shown the highest photocatalytic degradation efficiency of 100% with reusability for up to 5 cycles. Photocatalytic membranes are found to be feasible due to ease of recovery and better reusability. The limitations and efficient solutions for graphitic carbon nitride-based wastewater treatment technology are also emphasized in detail.

Summary: In this study, nitrogen carbide quantum dots doped nitrogen carbide nanosheet composite photocatalysts were successfully developed using a simple and effective method, which simultaneously produced hydrogen and degraded organic pollutants under visible light irradiation. The presence of acridine orange and aniline enhanced the hydrogen evolution efficiency, while methyl orange and phenol inhibited it. The synchronous mechanism of photocatalytic hydrogen evolution and organic pollutant degradation was proposed based on proton chain and energy band analyses.

Summary: A 3D microspherical Ag2CO3/BiOI/BiOCl heterojunction photocatalyst was successfully prepared by one-pot coprecipitation method. The composite photocatalysts were characterized by XRD, FTIR, SEM, TEM, UV-Vis DRS, N2 adsorption-desorption, XPS, ESR, and PL. The optimized 3% Ag2CO3-BiOI/BiOCl system showed more than 98% removal efficiency of Hg0 from simulated flue gas within 60 min. The photocatalyst had good acid, alkali, and NO resistance, but was significantly inhibited by SO2. The specific surface area of the Ag2CO3/BiOI/BiOCl photocatalyst was much higher than that of a single component, and the Hg0 removal efficiency remained around 94% even after six cycles.

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: This paper investigates the behavior and effects of fire in hermetic pressurized buildings. Unlike common buildings, the internal pressure in these buildings is maintained at standard atmospheric pressure, which is higher than the outside environment pressure in high altitude regions. Mechanical vents are used to supply the oxygen required for combustion in the sealed building during the early stage of a fire. A case study of a sealed pressurized hotel building in Tibet is conducted using Fire Dynamics Simulator (FDS) to study fire behavior under different design fire scenarios. The study provides information on evacuation time and suggests a fire protection design scheme based on analysis of oxygen concentration, gas content, temperature, visibility, and other indicators.

Summary: Ta3N5/CdS core-shell S-scheme heterojunction nanofibers were prepared by growing CdS nanodots on Ta3N5 nanofibers via a wet-chemical method. These nanofibers exhibit excellent photocatalytic degradation and mineralization performance for tetracycline, as well as efficient photocatalytic reduction performance for Cr(VI). The formation of a favorable core-shell fiber-shaped S-scheme heterostructure with tightly contacted interface and maximum interface contact area ensures effective photo-carrier disintegration and optimal photo-redox capacity, leading to superior photo-redox ability. Furthermore, critical environmental factors and the degradation products of tetracycline were evaluated, and the decrease in eco-toxicity of TC intermediates was confirmed.
