Summary: This study investigates the effects of adding Zr4+ and Ni2+ on the performance of hematite photoanode thin films in the photoelectrochemical hydrogen production process. Chemical mapping reveals the preferential segregation of Zr4+ at the interface and grain boundaries, while Ni2+ is mainly present on the hematite-free surfaces. The introduction of Zr4+ improves the back contact, facilitating electron collection and flow through the external circuit. Structural analysis also shows lattice distortions and strain field accumulation at the interface region.

Summary: Pre-deposition of powdered activated carbon (PAC) and alumina (AA) can effectively alleviate membrane fouling in biofiltration-facilitated gravity-driven membrane (GDM) systems. It improves the stable flux of the system and sequentially enhances the removal of dissolved organic carbon, UV254, and protein-like material. AA performs better than PAC in restricting the adhesion of soluble microbial products to the membrane and affects the porosity of the biofouling layer and the protein/polysaccharide ratio in extracellular polymeric substances (EPS).

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: Light-driven primary amine oxidation to imines integrated with H2 production presents a promising means to simultaneous production of high-value-added fine chemicals and clean fuels. A spatial decoupling strategy is proposed to overcome the limitations of poor charge separation and uncontrolled hydrogenation. The CoP@ZnIn2S4 photocatalyst exhibits directional and ultrafast carrier separation, leading to significantly higher production rate and selectivity for the photoconversion of benzylamine to N-benzylbenzaldimine.

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.
