The effect of the preparation method of Co/TiO2 catalysts on the performance in the liquid phase hydrogenation of cinnamaldehyde and crotonaldehyde has been studied. The Co/TiO2 catalysts were prepared by impregnation on titania (TiO2, P-25), sol-gel, and precipitation procedures. Different reduction-oxidation-reduction cycles were carried out in order to detect possible changes in the nature o...

20 The global analysis of the cellular lipid and protein content upon exposure to metal and metal oxide 21 nanoparticles (NPs) can provide an overview of the possible impact of exposure. Proteomic analysis has 22 been applied to understand the nanoimpact however the relevance of the alteration on the lipidic profile 23 JOURNAL OF INTEGRATED OMICS A METHODOLOGICAL JOURNAL HTTP://WWW.JIOMICS.COM ...

High-throughput manufacturing of nanomaterial-based products demands robust online characterization and quality control tools capable of continuously probing the in-suspension state. But existing analytical techniques are challenging to deploy in production settings because they are primarily geared toward small-batch ex-situ operation in research laboratory environments. Here we introduce an a...

High-quality Ti-doped ZnO films were grown on Si, thermally grown SiO2, and quartz substrates by atomic layer deposition (ALD) at 200°C with various Ti doping concentrations. Titanium isopropoxide, diethyl zinc, and deionized water were sources for Ti, Zn, and O, respectively. The Ti doping was then achieved by growing ZnO and TiO2 alternately. A hampered growth mode of ZnO on TiO2 layer was co...

ZnO nanoparticles have been prepared by a simple method in a short period of time. In this synthetic method, the sample was obtained using Zn(CH3COO)2·2H2O and a new template of hexamine salt. Their crystalline structure and morphology were studied by XRD and SEM. The optical properties of the sample were studied by UV–visible spectroscopy. The absorption spectr...

ZnO/TiO2 nanolaminates were grown on Si (100) and quartz substrates by atomic layer deposition at 200°C using diethylzinc, titanium isopropoxide, and deionized water as precursors. All prepared multilayers are nominally 50 nm thick with a varying number of alternating TiO2 and ZnO layers. Sample thickness and ellipsometric spectra were measured using a spectroscopic ellipsometer, and the parame...

There is a pressing need for information on the mobility of nanoparticles in the complex aqueous matrices found in realistic environmental conditions. We dispersed three different metal oxide nanoparticles (TiO2, ZnO and CeO2) in samples taken from eight different aqueous media associated with seawater, lagoon,river,andgroundwater,andmeasuredtheirelectrophoretic mobility, state of aggregation, ...

Recently, the rapid emergence of antibiotic-resistant pathogens has caused a serious health problem. Scientists respond to the threat by developing new antimicrobial materials to prevent or control infections caused by these pathogens. Polymer-based nanocomposite hydrogels are versatile materials as an alternative to conventional antimicrobial agents. Cross-linking of polymeric materials by met...

This paper presents an investigation on titanium dioxide (TiO2) and zinc oxide (ZnO) bilayer film, which is used as sensing membrane for extended-gate field effect transistor (EGFET) for pH sensing application. TiO2/ZnO thin films were deposited using sol-gel spin coating method on indium tin oxide (ITO) substrates. After the deposition, the bilayer films were annealed at constant temperatures ...

In this study adsorption of arsenic (As) onto TiO2 nanoparticles and the facilitated transport of As into carp (Cyprinus carpio) by TiO2 nanoparticles was examined. Adsorption kinetics and adsorption isotherm were conducted by adding As(V) to TiO2 suspensions. Facilitated transport of As by TiO2 nanoparticles was assessed by accumulation tests exposing carp to As(V) contaminated water in the pr...
