Summary: Incorporating plasmonic metal nanomaterials into semiconductor photocatalysts enhances their visible light response through localized surface plasmon resonance (LSPR) mechanisms. However, the presence of surfactants on the surfaces of plasmonic metal nanomaterials hinders their cocatalyst functionalities for photocatalytic hydrogen evolution. This study demonstrates a surfactant-free method to assemble Au nanoparticles (NPs) into Au colloidosomes (AuCSs), which can act as efficient cocatalysts when coupled with CdS to form Au-CdS composite photocatalysts.

Summary: By combining the localized surface plasmon resonance (LSPR) of metallic Ag and the chemically reactive Pt co-catalyst, a Ag-Pt bimetallic composite was coated on exfoliated defective graphitic carbon nitride nanosheets (C3N.NS) for plasmon hot electron-mediated photocatalytic H2 evolution. The (1:2) Ag-Pt/C3N.NS sample showed the highest activity (1.25 mmol g-1 h-1) under visible light irradiation, which was 35.7 and 1.7 times higher than that of Ag/C3NX NS and Pt/C3NX NS, respectively. The apparent quantum efficiency (AQE) of (1:2) Ag-Pt/C3NX NS reached 3.3% at 420 nm. The boosted photocatalytic capacity was attributed to the advantages of the LSPR effect of Ag particles and the Schottky barrier between Pt and C3NX NS, resulting in more electrons participating in the reduction reaction to enhance the photocatalytic H2 evolution performance.

Summary: The coupling of piezoelectric and plasmonic effects has been proven to enhance the photocatalytic performances. In this study, a new piezoelectric composite composed of Na0.5Bi0.5TiO3 nanoplates coated with Ag particles was prepared, showing excellent piezo-photocatalytic performances. The plasmonic effect of Ag nanoparticles widened the catalysts' spectral absorption range, and the electric field from the deformation of Na0.5Bi0.5TiO3 piezoelectric nanoplates greatly enhanced the separation and migration efficiencies of photo-generated charge carriers in Ag@ Na0.5Bi0.5TiO3 composites. With simultaneous full-spectrum lights and ultrasonic excitation, the piezo-photocatalytic activity of Ag@ Na0.5Bi0.5TiO3 achieved a significant degradation rate of 98.8% RhB in just 30 minutes.

Summary: The photocatalytic cumulative effect of a semiconductor is important for its activity. This study demonstrates that by synthesizing a well-designed Au@Pt/CdS/C3N4 heterostructure, the photocatalytic cumulative effect can be enhanced. The coating of CdS nanoparticle-clusters and Pt nanoparticles onto the Au nanocubes increases the charge separation and charge migration processes. The two-dimensional Au/CdS/C3N4 interface and the quasi-2D porous structure of CdS nanoparticles enhance the light harvesting and charge utilization processes, respectively.

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: 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.

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.

It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
