Summary: Renewable energy from sources like solar and wind is crucial for achieving a sustainable and CO2-free society in a short time. Green hydrogen is considered the most viable fuel for the next generation of fuel-cell electric vehicles and associated technologies. Solar water splitting, using visible-light-active photocatalysts like iron titanate (Fe2TiO5), shows promise for green hydrogen production, offering potential cost reductions in electrolysis-based H2 production. This review provides an overview of recent advances in using Fe2TiO5 as a semiconductor material for solar water splitting applications, including single photocatalytic systems and heterostructures such as Fe2TiO5/TiO2, Fe2TiO5/BiVO4, and Fe2TiO5/Fe2O3. Strategies for developing effective Fe2TiO5-based water-oxidation materials are also discussed.

Summary: This study introduces a surface modification technique using a laser printer to increase the effective contact area of a triboelectric nanogenerator (TENG) and improve its performance. By modifying the hydrothermal method, zinc sulfide (ZnS) nanostructures are directly introduced on an aluminum electrode as a positive layer, and different line patterns are printed on transparent sheets as a negative layer. This leads to significant improvements in the output voltage and current density of the TENG, as well as an ultrahigh instantaneous power density and energy conversion efficiency.

Summary: Hematite, a low-cost, nontoxic, and earth-abundant semiconductor, is still a promising photoanode material for PEC water splitting, but its PEC performance is hindered by fast charge carrier recombination rates and short diffusion lengths. Nanostructure implementation has been proposed to overcome this limitation and improve photon harvesting efficiency, but unmodified nanostructures may actually decrease the performance of PEC electrodes due to lack of internal electrical splitting fields.

Summary: In this work, BiVO4/Fe2TiO5/Co3O4 photoelectrodes were fabricated through simple chemical routes. The structures, morphologies, and optical properties of the photoelectrodes were characterized. Introducing Fe2TiO5 as a shell and loading Co3O4 catalyst enhanced the separation and injection efficiency of BiVO4 photoanodes. The formation of heterojunction and the presence of oxygen vacancies contributed to the improved performance of the photoanodes. The proposed BiVO4/Fe2TiO5 core-shell heterojunction loaded with Co3O4 catalyst exhibited a staggered type-II configuration.

Summary: The application of rapid and accurate diagnostic methods can significantly improve the survival rates of colorectal cancer. In this study, a non-targeted metabolomic approach based on iEESI-MS was used to identify metabolite ions associated with the progression of colorectal cancer. A support vector machine model was built using 10 differential metabolite ions to distinguish early-stage colorectal cancer from normal tissues, with a high prediction accuracy of 92.6%. The biomarker panel, specifically lysophosphatidylcholine (LPC) (18:0), showed good diagnostic potential in differentiating early-stage colorectal cancer from advanced-stage colorectal cancer.

Summary: We introduced an in-situ one-step hydrothermal method to prepare spinel films with nanostructures on low-cost Fe-Cr alloy substrates. The synthesized spinel film showed excellent low reflectance in the range of 0.3-2.5 µm and 2.5-13 µm, with values of 4.34% and 4.99% respectively, due to its uniform nano-micron structure on the surface. The spinel film can be an ideal candidate for ultra-wideband low-reflectance materials to improve the high precision of optical instruments.

Summary: The filling states of Ni-Oh and Fe-Oh in the NiFe2O4-based spinel are controllably regulated by introducing catalytically inactive MoSx, resulting in a salutary transition from high to medium e(g) occupancy state. The Mo-S hanging on the apical of octahedral sites plays a key role in the migration of electrons in the e(g) orbit of M-Oh, as confirmed by X-ray absorption spectroscopy and X-ray photoelectron spectroscopy. The modified surface with abundant unsaturated S atoms in amorphous MoSx shows superior water oxidation performance.
