Summary: This study investigates the modification of natural zeolite to enhance its ability to remove drugs and pesticides from water. The hydrothermal treatment with surfactant (CTAB) results in a structural rearrangement of the zeolite, making it more hydrophobic with a smaller specific area and a higher porosity. The modified zeolite exhibits significantly increased removal of the evaluated contaminants. The study concludes that hydrothermal modification with CTAB is a promising technique for using natural zeolites in the removal of emerging contaminants.

Summary: Metal chalcogenides face challenges in their application as visible-light-responsive photocatalysts due to fast recombination of charges and photo-corrosion. This study presents a rational design strategy to overcome these challenges by constructing S-scheme 1D/0D MCS/W heterojunction cauliflower-shaped assemblies. The resulting heterojunction showed enhanced visible light absorption, improved charge separation efficiency, and higher redox ability and long-term durability. The photocatalytic H-2 generation rate of the heterojunction assemblies was 25 times higher than that of the pristine MCS. This work provides deep insights into the rational construction of heterojunction assemblies for improved photocatalytic performance.

Summary: In this study, a photocurable resin based on bioactive glass (BAG) was prepared for additive manufacturing of BAG scaffolds. The influence of BAG on the physical properties of the resin and resulting 3D structures was investigated. The rheology and photocuring behavior of the resin, as well as the tomography of the resulting structures, were studied by varying the concentration of monomers, reactive diluent, light absorber, photoinitiator, non-reactive diluent, and BAG fillers. The optimal resin composition was found to be 55-60% BAG, 10% PEG-200, 1% PI, and 0.015% dye. The resulting green bodies exhibited dense glass scaffolds with good interlayer connection and surface finishing, indicating promising mechanical behavior. This study provides valuable insights for the preparation and optimization of high density glass/ceramic slurries for printing applications.

Summary: This review article discusses the progress and applications of various minerals in photocatalysis. Natural minerals, such as silicate and non-silicate minerals, offer cost-efficiency and can be hybridized with photocatalysts to produce synergistic effects. Silicate minerals, due to their unique structures and properties, can enhance adsorption capacity and photocatalytic activity. Non-silicate minerals can serve as catalyst supports and photocatalysts after modification. Dye-sensitized minerals have been proven to be superior photocatalysts. This work provides an overview of mineral-supported photocatalysts and explores the synergistic effects between different mineral substrates and photocatalysts, as well as the potential applications of natural minerals in photocatalysis.

Summary: Additively manufactured hollow-strut bioceramic scaffolds offer a promising strategy for patient-tailored bone tissue engineering, providing pathways for nutrient and cell transport and promoting osseointegration and vascularization. This study presents a slurry based additive manufacturing approach for modified diopside bioceramics, producing hollow-strut scaffolds with diverse cross-sectional forms. Mechanical characterization showed that square outer cross-sections for hollow struts in woodpile scaffolds result in higher compressive strength compared to solid cylindrical strut scaffolds, despite lower density. Hollow struts in bioceramic scaffolds significantly enhance cell attachment and proliferation and have potential for new bone tissue formation. This work provides a controlled method for extrusion-based 3D printing of hollow strut scaffolds, enhancing functional and mechanical performance in bone tissue engineering scaffolds.

Summary: To investigate the synergistic action of differently prepared Ni-ZrO2 phase boundaries in methane dry reforming, three catalyst systems including an inverse near-surface intermetallic NiZr catalyst precursor, bulk-intermetallic NixZry material, and a supported Ni-ZrO2 catalyst were compared. All three catalysts exhibit stable and highly efficient methane dry reforming activity with improved resistance to coke deposition due to the presence of extended Ni-ZrO2 phase boundaries formed by in situ activation. Methane is decomposed to carbon at metallic Ni-0 surface sites, while CO2 is converted to CO at reduced Zr centers at the phase boundaries. The surface-ZrO2 modified bulk Ni-0 catalyst shows the best decoking and carbon conversion conditions, attributed to the dispersed ZrO2 islands and short diffusion pathways for carbon.

Summary: Ambient pressure drying (APD) has the potential to reduce the cost of aerogel fabrication. This study investigates the effect of different silylation agents on the re-expansion of SiO2 aerogels after drying. The results show that while some physical properties were significantly affected by re-expansion, silylation did not always result in full re-expansion. The impact of silylation in tailoring the re-expansion behavior is crucial for APD of monolithic aerogels.

Summary: Three compositions of high-entropy carbides were synthesized using a modified Pechini process and citric acid as a cation chelating agent and carbon source. Single phase high-entropy carbides were formed through pyrolysis and spark plasma sintering at a relatively low temperature of 1800 degrees C. The dispersion of cations in the polymer precursor resulted in improved compositional homogeneity and a finer microstructure in the polymer-derived materials, leading to enhanced fracture toughness with a K-IC value of 4.29 MPa.m(1/2) achieved for (TiHfVNbTa)C.
