Two-dimensional (2D) nanoporous heterostructured composites formed by uniformly coating individual monolayers with porous layers introduce unparalleled opportunities to improve and optimize the electrochemical performances of 2D materials. Here, an all-porous carbon heterostructure composed microporous nanoflakes decorated nanodots has been developed. Interestingly, resol-F127 micelles self-assemble on surface zeolitic imidazolate framework (ZIF) in form a nanodot array, yielding...
Novel CuO nanoparticle-capped ZnO nanorods have been produced using a pulsed laser deposition (PLD) method. These are shown to grow by CuO-nanoparticle-assisted vapor-solid-solid (V-S-S) mechanism. The photoluminescence (PL) accompanying ultraviolet illumination of these capped nanorod samples shows large variations upon exposure trace quantities H2S gas. present data suggest that both the Cu-doped stem and capping nanoparticle contribute optical sensing with CuO-ZnO nanorods. This study...
α-Phase formamidinium lead iodide (FAPbI3) perovskite solar cells (PSCs) have garnered significant attention, owing to their remarkable efficiency. Methylammonium chloride (MACl), a common additive, is used control the crystallization of FAPbI3, thereby facilitating formation photoactive α-phase. However, MACl's high volatility raises concerns regarding its stability and potential impact on device. In this study, we partially substituted MACl with n-propylammonium (PACl), which has long...
Tin halide perovskites are promising candidates for lead-free perovskite solar cells due to their ideal bandgap and high charge-carrier mobility. However, poor crystal quality rapid degradation in ambient conditions severely limit stability practical applications. This study demonstrates that incorporating UiO-66, a zirconium-based MOF, significantly enhances the performance of tin (TPSCs). The unique porous structure abundant carboxylate groups UiO-66 improve crystallinity film FASnI₃,...
Owing to the variation in metal activity, aluminum-steel structure of wing wall panels is particularly susceptible galvanic corrosion. Because concealed nature defects and significant disparity physical properties materials, detecting thinning structures proves highly challenging. To tackle these issues, this study introduces a pulsed eddy current detection technique capable accurately identifying various types within structures. First, finite element simulation software employed establish...
Tin halide perovskite solar cells (PSCs) have attracted great attention in very recent years due to their low toxicity, suitable band gap, and high light absorption coefficient. However, the power conversion efficiency (PCE) stability of Sn-based PSCs are still much lower than that lead-based counterparts. The main reason comes from Sn2+ ions spontaneously oxidizing into Sn4+ under ambient air conditions. resulting self-p-type doping layer becomes unsuitable leads poor photovoltaic...
Vertically aligned CdTe–ZnO composite nanorods are constructed on the indium tin oxide substrates by layer-by-layer deposition of CdTe quantum dots ZnO nanorod arrays. The shell forms an intact interface with wurtzite nanorod, and its thickness can be accurately tuned changing cycles. Photoluminescent measurements further disclose band alignment between core, which makes exhibiting good photoelectron-chemical properties being a prospective material for removal phenol from wastewater under...

ZnO nanorods (NRs) are known for ultra-sensitive biomolecule detection through fluorescence enhancement. In this work, we demonstrate that NR arrays grown on Ag layers can significantly improve the enhancement up to 86 times compared bare Si and be modified in a controlled manner by varying thickness. The much improved waveguide properties attributed high reflectance of their tuning effect diameters NRs. Our results provide deep insight into mechanism NRs-based platform.
The photoluminescence-based O<sub>2</sub> sensing properties of PLD ZnO nanorods at elevated temperatures depend sensitively on their (incident fluence determined) morphology and defect density.

ZnO nanorods produced hydrothermally, using different precursor concentrations, show strikingly morphologies and photoluminescence properties after encapsulation in silica. These differences are traced to the nanorod growth chemistry.
