Summary: In this study, a collaborative strategy is proposed to disperse Pt on zinc-vacancy-riched ZnIn2S4 (Pt/V-Zn-ZIS) for investigating the effect of lignin structure during the photo-reforming process with lignin models. Theoretical calculations and experimental results demonstrate that lignin model substances with more nucleophilic group structures exhibit a stronger tendency for photo-reforming reactions. Additionally, the presence of a Pt-S electronic channel formed by occupying Pt atom onto zinc vacancies in ZnIn2S4 effectively reduces the energy barrier of H-2 evolution and enables the selective oxidation of lignin model from C alpha-OH to C alpha = O under simulated sunlight. Natural lignin is used to further validate this selective oxidation mechanism. This study provides insights into the photo-reforming mechanism of lignin models and the influence of lignin structure during the process.

Summary: In this study, a novel modular photo-thermo-reactor (MPTR) is proposed for efficient and cost-effective hydrogen production from methanol steam reforming. The MPTR utilizes synergistic photo-thermo-catalysis (PTC) with Pt/CuO catalyst and thermo-catalysis (TC) with Cu/ZnO/Al2O3 catalyst in a cascade way using composite catalyst beds. A multiphysics model is established to optimally design the MPTR, covering optical, flow, thermal, and chemical sub-processes. The predicted performance indicates that the MPTR achieves the highest overall solar-to-hydrogen efficiency of 24.1% and annual hydrogen production of 1211 Nm(3)/m(2) in Xi'an, China.

Summary: Efficient and low-cost electrocatalysts for hydrogen evolution reaction (HER) are synthesized by synthesizing two different types of CoS2 under low sulfur and high sulfur concentration conditions. The study shows that CoS impurity phase is easily formed when the sulfur concentration is low, while at high sulfur concentration, the growth of CoS impurity phase is inhibited and leads to phase-pure CoS2. The electrochemical investigation reveals that the CoS2 (HS) electrode has a higher onset potential and a lower required overpotential compared to the CoS2 (LS) electrode.

Summary: Discordant abundances of different immune cell subtypes is regarded to be an essential feature of tumour tissue. Direct studies in Prostate cancer (PC) of intratumoral immune heterogeneity characterized by immune cell subtype, are still lacking. Using the single sample gene set enrichment analysis (ssGSEA) algorithm, the abundance of 28 immune cells infiltration (ICI) were determined for PC. A NMF was performed to determine tumour-sample clustering based on the abundance of ICI and PFS information. Hub genes of clusters were identified via weighted gene co-expression network analysis (WGCNA). The multivariate dimensionality reduction analysis of hub genes expression matrix was carried out via principal component analysis (PCA) to obtain immune score (IS). We analysed the correlation between clustering, IS and clinical phenotype. We divided the 495 patients into clusterA (n = 193) and clusterB (n = 302) on the basis of ICI and PFS via NMF. The progression-free survival (PFS) were better for clusterA than for clusterB (p < 0.001). Each immune cell subtypes was more abundant in clusterA than in clusterB (p < 0.001). The expression levels of CTAL-4 and PD-L1 were lower in clusterB than in clusterA (p < 0.001 and p = 0.006). We obtained 103 hub genes via WGCNA. In the training and validation cohorts, the prognosis of high IS group was worse than that of the low IS group (p < 0.05). IS had good predictive effect on 5-year PFS. The expression of immune checkpoint genes was higher in the low IS group than in the high IS group (p < 0.01). Patients with low IS and receiving hormone therapy had better prognosis than other groups. The combination of IS and clinical characteristics including lymph node metastasis and gleason score can better differentiate patient outcomes than using it alone. IS was a practical algorithm to predict the prognosis of patients. Advanced PC patients with low IS may be more sensitive to hormone therapy. CXCL10, CXCL5, MMP1, CXCL12, CXCL11, CXCL2, STAT1, IL-6 and TLR2 were hub genes, which may drive the homing of immune cells in tumours and promote immune cell differentiation.

Summary: Regulating the energy barrier of *COOH is crucial for the rate determining step in the photocatalytic reduction of CO2 to produce CO gas. In this study, an appropriate Zn vacancy on ZnIn2S4 was synthesized to enhance the photocatalytic CO2 reduction capacity (CO: 5.63 mmol g(-1) h(-1)) and selectivity (CO: 97.9%). Different sulfhydryl groups were used to regulate the formation of Zn vacancies in ZnIn2S4, leading to the generation of unsaturated sulfur coordination state adjacent to the Zn vacancy with fewer electrons compared to ZnIn2S4 without Zn vacancy. Experimental analysis and theoretical calculations demonstrated that the appropriate Zn vacancy shifted the Gibbs free energy of *COOH from endothermic to exothermic during the photoreduction of CO2. This work provides an engineering method to optimize cation vacancies and improve the efficiency of photocatalytic CO2 reduction by adjusting the energy barrier of intermediates.

Summary: This study demonstrates that Ru nanoparticles supported on natural halloysite nanotubes can enhance the photothermal catalytic activity and selectivity of CO2 methanation under continuous flow conditions. The optimized catalyst exhibits a photothermal catalytic performance of 1704 mmolCH(4) g(cat)(-1) h(-1) with 93% CH4 selectivity and 68% CO2 conversion, surpassing other Ru-based catalysts in photothermal CO2 reduction. The excellent catalytic performance is attributed to the unique mesoporous tubular structure, efficient light-to-heat conversion, and interfacial interactions between halloysite nanotubes and Ru. This method of utilizing natural minerals as support provides a convenient approach for the rational design of abundant and low-cost catalysts for efficient photothermal catalytic CO2 reduction.

Summary: A Ru/In2O3 catalyst is reported for efficient and stable photothermal CH3OH production from CO2 hydrogenation under atmospheric pressure. The catalyst demonstrates a remarkable solar CH3OH production, which is more than 50 times higher than that of pure In2O3 and surpasses other reported In2O3-based photothermal catalysts. Detailed characterizations show that the interaction between Ru and In2O3 enhances the activation of CO2 and H-2, and Ru modulates the electronic structure of In2O3, promoting the generation of oxygen vacancies for CH3OH formation. This work provides a rational design approach for efficient catalysts in solar CH3OH production from CO2 hydrogenation under mild conditions.

Summary: In this study, ultraviolet irradiation was used to purify the membrane tanks and control membrane biofouling in biofiltration-facilitated GDM systems. The permeate flux significantly increased after UV irradiation, primarily due to the decreased cake layer resistance. UV irradiation also improved the permeability of the biofouling layer, reduced protein content, and altered the bacterial community structure on the membrane surface. Overall, the in-situ application of UV can be an effective strategy to mitigate membrane biofouling.

Summary: This paper investigates the application of gravity-driven up-flow slow biofilter (GUSB) before gravity-driven membrane (GDM) systems to mitigate membrane fouling and explores the spatial distribution of fouling characteristics. The study finds that GUSB pretreatment reduces the cake layer resistance (Rc) and membrane pore resistance (Rp), resulting in an increase in permeate flux. The ratio of protein to polysaccharide (PN/PS) is highly correlated with nanoparticle size and influences the bacterial community and structure of the biofouling layer.
