The catalytic combustion of methane has gained much attention as a sustainable technology, due to concerns about the environmental impact unburnt emissions from natural gas vehicles. Researchers have explored alternatives precious metal catalysts for combustion, with focus on perovskite oxides known their excellent activity and sintering-resistance capacity. In this study, LaFeO3 material was synthesized subsequently subjected nitric acid etching treatment modify its surface. It found that...
Resistive switching (RS) for nonvolatile data storage is a highly relevant field of research. Up to now, RS devices are fabricated via semiconductor processing technologies. This poses the question whether integration chemically tailored nanoparticles, either consisting valence change or phase materials, can be integrated in nanoelectrode configurations order explore their functionality applications. review discusses properties such nanoparticles by means selected examples both nanoparticle...
The wet-chemical synthesis of 3D confined antimony nanoparticles (Sb-NP) at low and high temperatures is described. Using reaction conditions that are mild in temperature strong reducing power allows the amorphous Sb-NP stabilized with organic ligands. Exchanging ligand 1-octanethiol by iodide enabled to investigate unusual stability this metastable material through simultaneous thermal analysis combining differential scanning calorimetry thermogravimetric analysis. Additionally, situ powder...
Microgels are versatile materials with applications across biomedicine, science, and beyond. Their controllable size composition enables tailoring specific properties, yet characterizing their internal structures on the nanoscale remains challenging. Super-resolution fluorescence microscopy (SRFM) effectively analyzes sub-μm structures, including microgels, offering a tool for investigating more complex systems such as core-shell microgels. Understanding structure, in particular...
Vanadium(IV) chalcogenide materials are of increasing interest for use in catalysis and energy conversion-related applications. Since no ternary compounds yet known the V–Se–Te system, we studied VwSeyTe2–y (w = 1.10, 1.13; y 0.42, 0.72) phases crystallizing space group P3m1 (no. 164). Two single-crystal specimens with differing compositions a solid solution were obtained using ceramic method. All products characterized by either or powder X-ray diffraction. The lattice parameters increase...
