Cathodic electrodeposition of SnS thin films from aqueous solution [PDF]

open access: yes, 1996
SnS thin films were prepared by cathodic electrodeposition on ITO/glass and Ti substrates from a solution containing SnCl2 and thiosulphate ions. Cyclic voltammetry experiments were performed to elucidate the electrodic processes occurred when potentials

Preferred orientation of n-hexane crystallized in silicon nanochannels: A combined x-ray diffraction and sorption isotherm study

open access: yes, 2009
We present an x-ray diffraction study on n-hexane in tubular silicon channels of approximately 10 nm diameter both as a function of the filling fraction f of the channels and as a function of temperature. Upon cooling, confined n-hexane crystallizes in a

Mössbauer diffractometry on polycrystalline (57)Fe3Al [PDF]

open access: yes, 2002
A Mossbauer powder diffractometer was used to measure diffraction patterns from polycrystalline foils of (Fe3Al)-Fe-57. The intensities of Bragg diffractions were measured as a function of the energy of the incident photon.

Films of Ni–7 at% V, Pd, Pt and Ta–Si–N as diffusion barriers for copper on Bi2Te3 [PDF]

open access: yes, 1998
Films of Ni–7 at% V, Pt, Pd, and Ta40Si14N46, each approximately 100 nm thick, were magnetron-deposited and interposed between about 250 nm thick copper overlayers and Bi2Te3 single-crystalline substrates.

Morphological, mineralogical and geochemical characterization of Ngaoundal soils (Adamawa-Cameroon): Implications for weathering mechanisms and trajectories in tropical zones

open access: yesGeosystems and Geoenvironment
Ngaoundal, located in the Adamaoua region of Cameroon, has a tropical climate and is known for its characteristic soils. The aim of the present study was to evaluate the action of weathering on Ngaoundal's lateritic soils.

X-ray Fresnel diffractometry for ultralow emittance diagnostics of next generation synchrotron light sources

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2015
A novel technique using single-slit x-ray Fresnel diffraction has been developed to resolve μm-order electron beam sizes at the insertion devices (IDs) of photon beam lines. The new technique is promising for diagnostics of next-generation light sources,

Validation of ultrasonic velocity estimates of wood properties in discs of radiata pine

open access: yesNew Zealand Journal of Forestry Science, 2017
Background Measurement of microfibril angle (MFA) in the S2 layer of the cell walls of wood using speed of sound in wood has become a common way to estimate wood stiffness and stability. Measurements across the radius of a disc can be critical, but sonic
