Abstract Hybrid glasses derived from meltable metal‐organic frameworks (MOFs) have emerged as a new class of amorphous materials. Combining the porosity MOFs with processing ability glasses, they are thought to enable wholly range functional compounds. By way example, it is demonstrated here how intrinsic obtained zeolitic imidazolates (ZIFs) can be used overcome selectivity‐sensitivity trade‐off in electroactive gas sensing. For this, composites fabricated which metallophthalocyanines...
The chemical routes of metal oxidation in presence hydrogen peroxide solutions are tailor-made for the synthesis biocompatible oxide surfaces with clean intermediate and end products, such as oxides, hydroxides, water. hydrolysis titanium is particularly interesting medical applications, forming micro- nanoscale titania surfaces. In this paper, content solution revised, allowing fabrication gas sensor devices based on nanoporous titania. Nanopore microcrack formations were discussed detail...

Unlike the conventional one-dimensional (1D) core-shell nanowires (NWs) composed of p-type shells and n-type cores, in this work, an inverse design is proposed by depositing ZnO (shell) layers on surface CuO (core) NWs, to have a comprehensive understanding their conductometric gas-sensing kinetics. The morphologies bare NWs were investigated field emission scanning electron microscope (FE-SEM). shell layer was presented overlay images taken dispersive X-ray spectroscopy (EDX)...
