The heterogeneous reaction of ozone (O3) with 200 nm squalene nanoparticles is studied using near-edge X-ray absorption fine structure (NEXAFS) and ultraviolet (UPS) and X-ray photoelectron spectroscopy (XPS). Photoelectrons are detected from free nanoparticle beams using a velocity map imaging (VMI) spectrometer capable of detecting photoelectrons with up to 40 eV of kinetic energy. Heterogene...
In this paper, ZnIn(2)S(4) perpendicular nanosheet films have been directly deposited on FTO substrates by a facile hydrothermal method and investigated as the electrode materials for solar cells. The crystal structure, morphology, and optical properties of the obtained ZnIn(2)S(4) films were characterized by measurements such as X-ray diffraction (XRD), scanning electron microscopy (SEM), tran...
ion of H2 + by O occurs with 55% yield to produce the desired CCl2 ; however, CHCl2 produced by proton abstraction, with m/z only 1 amu greater than the desired product, is a significant minor ionic reaction product. Since theWien filter has a mass resolution of at bestm/DmE 40, we can only partially separate ions within 1 amu of each other at m/z E 80, specifically CCl2 and CHCl2 . It was init...
This paper gives an account of our progress towards performing femtosecond time-resolved photoelectron diffraction on gas-phase molecules in a pump-probe setup combining optical lasers and an X-ray free-electron laser. We present results of two experiments aimed at measuring photoelectron angular distributions of laser-aligned 1-ethynyl-4-fluorobenzene (C(8)H(5)F) and dissociating, laser-aligne...
Sol-gel technique was used to coat multiwall carbon nanotubes (MWCNTs) with anatase titania to increasing the surface area and improve the photocatalytic activity of TiO2. Room temperature ballistic conduct of MWCNT combined with semiconducting behavior of anatase brought about a photocatalytic improvement of ~37 % with respect to the highest methyl orange decolorization flair. For characteriza...
The novel orange to red color Bi 24 Al 2- x Cr O 39 (0≤ ≤ 0.5) compounds were successfully synthesized by the solid state method. With increase of content, colors are tuned from dark red. X-ray diffraction patterns all samples indexed with cubic 2 structure space group I 23. oxidation in oxide is confirmed be +4 valence photoelectron spectroscopy (XPS) and electron paramagnetic resonance (EPR)....
Abstract In this article, we report single crystal growth of superconducting binary compound Pb 2 Pd. The is well characterized through x-ray diffraction, selected area electron transmission microscopy, field emission scanning microscopy and photoelectron spectroscopy. bulk nature the synthesized determined AC susceptibility magneto-heat capacity measurements. specific heat jump at transition s...
X-ray reflectometry (XRR) and photoelectron spectroscopy (XPS) measurements (core levels valence bands) were made of Cu thin films that prepared coated by capping Ta layers with different thicknesses (5, 10, 15, 20, 30 Å), are presented. The XRR XPS 4f-spectra revealed a complete oxidation the protective layer up to thickness 10 Å. From 15 Å, pure Ta-metal line appeared in 4f-spectrum, contribu...
The Photo-Emission and Atomic Resolution Laboratory (PEARL) is a new soft X-ray beamline and surface science laboratory at the Swiss Light Source. PEARL is dedicated to the structural characterization of local bonding geometry at surfaces and interfaces of novel materials, in particular of molecular adsorbates, nanostructured surfaces, and surfaces of complex materials. The main experimental te...
