This study presents an innovative approach to integrated energy systems by combining solar energy harvesting and electrochemical charge storage in a single modular platform. By strategically incorporating a MoS/NaTaO heterostructure material, we have developed a photo-rechargeable zinc-ion capacitor (PR-ZIC) that utilises the synergistic benefits of this unique configuration. The photoactive MoS/NaTaO cathode effectively absorbs light and charges the capacitor, enabling continuous light-driven operation.

Unlike the conventional matrix-assisted laser desorption/ionization, there is no interference in the SALDI with matrices for the low mass analyte peaks (/ < 700). The focus of this work is to develop substrates based on nanomaterials to obtain higher sensitivity, better reproducibility, and easier preparation.

A potential, clean, renewable alternative fuel, which may be produced from solar energy, stored and safely transported, is hydrogen. In this work, bare CrTiO2 NTs were fabricated using an in situ anodizing process.

Nickel-platinum was then deposited on the surface of these Fe-TNTs samples by an electroless process during different time periods. SEM, XRD and UV-vis absorption spectroscopy was used to study the surface morphologies, composition and optical properties of the synthetic samples.

Field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD) were used to study the morphology and elemental composition of the synthetic samples. UV-Vis diffuse reflection spectroscopy (UV-Vis DRS) was sued to investigate the optical features of the samples.
View Article and Find Full Text PDFThe chemical bath deposition (CBD) method was successfully applied to prepare WTiO nanotube arrays co-deposited with chromium, iron and chromium-iron nanoparticles. Various methods have been used in the characterization of synthetic co-deposited nanostructures. WTiO nanotubes can keep the nanotubular structures at low iron concentration in the CBD solution, as indicated by our FESEM results.
