Metal oxide nanoparticles are essential in various applications, and the synthesis through gas-phase generation methods offers a rapid reliable pathway for nanoparticle production. Yet achieving precise control over their formation remains challenging due to complex nature of oxidation processes. While bulk states can be assessed via off-line measurements, dynamic surface is more difficult monitor optimize real time. Here, we investigate state unsupported tin using an aerosol sample-delivery...
Nickel (Ni)-promoted Molybdenum (Mo)-based catalysts are used for hydrotreatment processes in the chemical industry where exposed to high-pressure H2 at elevated temperature. In this environment, catalyst transforms into active phase, which involves reduction of oxide. Here, we report on first situ study alumina supported Ni- and Mo-based 1 mbar using ambient-pressure X-ray photoelectron spectroscopy (APXPS). The confirms that mixing Ni Mo lowers temperature both Mo-oxide as compared...
Here we report on an experimental and theoretical investigation of the long-wavelength infrared (LWIR) photoresponse photodetectors based arrays three million InP nanowires with axially embedded InAsP quantum discs. An ultra-thin top indium tin oxide contact combined a novel photogating mechanism facilitates improved LWIR normal incidence sensitivity in contrast to traditional planar well photodetectors. The electronic structure discs, including strain defect-induced effects, optical...
In the strive towards a circular economy, metal waste recycling is growing industry. During process, particulate matter containing toxic and allergenic metals will be emitted to air causing unintentional exposure humans environment.In this study detailed characterization of particle emissions workplace exposures were performed, covering full size range from 10 nm µm, during three different material flows: Waste electrical electronic equipment (WEEE), scrap, cables.Both direct-reading...
Hygroscopic materials which possess high moisture adsorption capacity were successfully upgraded by the functionalization of sodium chloride (NaCl) using two nuances oxides. A procedure was developed to first prepare submicron-sized NaCl crystals; thereafter, these crystals coated choice either titanium dioxide (TiO 2 ) or silica (SiO enhance hygroscopic properties and prevent its premature deliquescence. After coating, several analytical techniques employed evaluate obtained composite...
Spark ablation is an advantageous method for the generation of metallic nanoparticles with defined particle sizes and compositions. The reaction metal particles carrier gas during synthesis and, therefore, incorporation those light elements into structural voids or even compound formation was confirmed hydrides oxides but has only been suspected to occur nitrides. In this study, dispersed Mo3Ni2N Mo Janus morphology, were obtained by spark discharge as a result ionization characterized using...
Palladium nanoparticles were produced by a chemical reagent-free and versatile method called spark ablation with control over particle size density. These used as catalytic seed particles for gallium phosphide nanowire growth metalorganic vapour-phase epitaxy. Controlled of GaP nanowires using significantly small Pd between 10 40 nm diameter was achieved varying several parameters. Low V/III ratios below 2.0 promote higher Ga incorporation into the nanoparticles. Moderate temperatures under...
Abstract Waste of electrical and electronic equipment (WEEE) is one the fastest-growing waste streams in EU. The airborne occupational environmental exposures generated by this handling are poorly quantified, growing use nanomaterials electronics adds to uncertainty risk assessment. Emission personal exposure measurements were carried out during industrial recycling for three different metal flows: WEEE, scrap cables. Size distributions number-, mass- lung deposited surface area...
