This work aimed to prepare nanostructures of ZnO with various lasers, testing them as photocatalysts, and comparing their morphology activity in the degradation organic pollutants aqueous media. nanospheres (ns-ZnO) nanorods (ms-ZnO) were prepared via laser ablation a Zn metal plate water using nanosecond- millisecond-pulsed respectively. The obtained materials characterized set optical, structural, surface-science techniques, such UV-vis spectroscopy, X-ray diffraction (XRD), transmission...
In the present study, a mesoporous photocatalyst based on Au–Pd nanoparticles incorporated into g-C3N4 was prepared by coassembly method using melamine as carbon and nitrogen source, polyvinyl pyrrolidone dispersing agent, pulse laser ablation in liquid technique for preparing gold subsequent decoration with Pd nanoparticles. At final stage, Au–Pd/g-C3N4 nano-photocatalyst obtained via low-ramping pyrolysis an argon atmosphere. The activity of catalyst related to its structure, which...
A homogeneous dispersion of nano iron oxide ( IO ) crystallites inside the hydroxyapatite HA particles was achieved by a co‐precipitation method. This highly stable colloidal magnetic composite HAIO made without use any surfactants. The in situ generated powders showed submicron with ~5 nm inside. phase analysis results presence and no tertiary phase. enhancement relative peak intensities increased percentage X‐ray diffraction suggests formation together affecting purity latter, which is...
Metal-metal-, ceramic-metal-composites (MMC, CMC) and related functional materials are steadily gaining interest for practical applications. This invited overview paper is divided into three parts. First, the importance of interfaces in material science emphasized, then basics computer modeling on atomic scale outlined, followed by description some interface examples their Atomistic requires specific determination orientation relationship between both crystal lattices facing heterogeneous...
Abstract An den beiden taktischen Formen des Polymethylmethacrylats werden Viskositätsmessungen und Lichtstreuungsmessungen gemacht, um Knäueldimensionen Unterschiede im thermodynamischen Verhalten zu ermitteln. Die isotaktische Form hat in allen Lösungsmitteln die größere Persistenzlänge. Thetapunkte beider sind verschieden, Wobei es vom Lösungsmittel Abhängt, welche höheren Thetapunkt hat. Der 2. osmotische Virialkoeffizient Butylchlorid verhält sich für beide “normal”. Im...
Article Die Bestimmung des Trägheitsradius und zweiten osmotischen Virialkoeffizienten von Polymeren in Lösung aus Röntgenkleinwinkelmessungen was published on March 1, 1968 the journal Zeitschrift für Physikalische Chemie (volume 58, issue 1_4).
Despite the success in use of superparamagnetic iron oxide nanoparticles (SPION) for various scientific applications, its potential biomedical fields has not been exploited to full potential. In this context, an situ substitution Mn(2+) was performed SPION and a series ferrite particles, MnxFe1-xFe2O4 with varying molar ratio : Fe(2+) where 'x' varies from 0-0.75. The particles obtained were further studied MRI contrast applications showed appreciable enhancement their properties. Manganese...
In this paper, we report a new, simple method for the synthesis of CdS and ZnS nanoparticles (NPs) prepared in basic aqueous medium using metal xanthate as sulfur source. The structure, morphology, size distribution, optical band gap, photocatalytic properties newly obtained nanomaterials were investigated by UV-Vis spectroscopy, X-ray diffraction, transmission electron microscopy. results show that both crystallized cubic phase formed NPs with average sizes 7.0 4.2 nm ZnS, respectively. A...
Abstract Die Form der Streukurven von gelösten Polymethylmethacrylaten (PMMA) ist eine Funktion Taktizität. In Streukurve des syndiotaktischen PMMA läßt sich Einfluß einer Periodizität erkennen. Eine quantitative Deutung gelingt durch Überlagerung Helixstreukurve mit Knäuelstreukurve. Dabei muß gesetzt werden H = 21 Å, R 4 Å und a 13 ( sind die Identitätsperiode bzw. Radius Helix, Persistenzlänge Knäuels.) isotaktischen zeigt nahezu den Verlauf, für Fadenknäuel nach Kratky et al. [2–5] zu...
Titanium dioxide has been extensively studied in recent decades for its important photocatalytic application environmental purification. The search a method to narrow the optical band gap of TiO 2 plays key role enhancing application. epitaxial rutile and anatase thin films deposited by helicon magnetron sputtering on sapphire SrTiO 3 substrates was correlated lattice constants. 3.03 eV bulk-rutile increased 3.37 sapphire. 3.20 bulk-anatase increases 3.51 . In order interpret this expansion,...
