Title: Portable chamber for the study of UHV prepared electrochemical interfaces by hard x-ray diffraction

Abstract

We report on a new electrochemical cell setup, combined with a portable UHV chamber, for in situ x-ray diffraction using synchrotron radiation. In contrast to more traditional electrochemical sample preparation schemes, atomically clean and well-ordered surfaces are routinely prepared by UHV methods, even in the case of reactive elements or alloys. Samples can be transferred from larger UHV systems into the portable chamber without exposure to ambient air. They can then be studied successively in UHV, in controlled gas atmospheres, and in contact with electrolyte solutions under applied electrochemical potential. The electrochemical setup employs a droplet geometry, which guarantees good electrochemical conditions during in situ x-ray measurements combined with voltammetry. We present first experimental results of Cu deposition on GaAs(001) and on freshly produced nanometric Pd(001) islands on Cu{sub 0.83}Pd{sub 0.17}(001), respectively.

  • We present the development of a novel UHV compact reflectometer designed and developed for the investigation of magnetic properties of thin films at the ID12-E.S.R.F. beamline. This new instrument is dedicated to x-ray resonant magnetic reflectivity experiment from thin film or multilayered sample. We present the principles of this versatile and simple instrument. We report also the results of resonant magnetic reflectivity experiments carried out for the Fe/Ir multilayers. This will demonstrate the capability to record either angle or energy dependent measurements at the L edges of Ir simultaneously to the XMCD spectra.
  • Microstructure of a-WO{sub 3} films prepared by electron beam vacuum evaporation was examined based on XRD. The peak positions in the observed PDFs corresponded with those in the PDFs calculated from the crystal structure of hexagonal WO{sub 3} and WO{sub 3}{center dot}1/3H{sub 2}O, and the framework structure of the films was therefore thought to consist of the basic structure of these crystals, three-, four-, and six-membered rings formed by WO{sub 6} octahedra. Microcluster models in which the atomic arrangement was similar to that of hexagonal WO{sub 3} were assumed and investigated in detail. The pair distribution functions calculated from thesemore » models showed good agreement with the observed values, and the structure of a-WO{sub 3} films was consequently suggested to consist of clusters in which the octahedra were arranged in the same manner as those in hexagonal WO{sub 3}.« less
  • Iron-aluminium alloys of composition Fe{sub 50}Al{sub 50} and Fe{sub 75}Al{sub 25} were produced by mechanical alloying (MA) of the pure elemental powders. A structural refinement of X-ray powder data on the mechanically alloyed products according to the Rietveld method has detailed the progressive dissolution of aluminium into the lattice of {alpha}-iron as a function of MA time. With respect to pure iron, a volume expansion of {approx}3% is measured in both compositions mechanically alloyed for 32 h. In the iron and aluminium phases, the Debye-Waller static disorder increases as a function of MA time and the intrinsic shape of themore » peak profiles becomes predominantly Cauchy. These changes are accompanied by an increase in the average microstrain and by a reduction in the average crystallite size (which includes also the effect of dislocations). The Moessbauer spectra show that in the equiatomic case the initial sharp magnetic sextet of {alpha}-iron is progressively reduced and is replaced by a doublet, while for the Fe{sub 75}Al{sub 25} composition a broad magnetic sextet is eventually obtained. Thermal scans at 600 C of the specimens mechanically alloyed for 2, 4 and 8 h precipitate essentially the Al{sub 5}Fe{sub 2} phase. In the case of the Fe{sub 50}Al{sub 50} specimens, annealing of the powders mechanically alloyed for 16 and 32 h precipitates mainly the partially ordered FeAl intermetallic compound, while no ordering is obtained in the Fe{sub 75}Al{sub 25} case.« less
  • Hydrothermal synthesis has proven to be a cost-effective, energy-efficient approach for the manufacture of lithium iron phosphate (LiFePO{sub 4}) and its related materials. However, hydrothermally prepared LiFePO{sub 4} typically suffers from antisite defects, where some of the iron resides on lithium sites and restricts lithium-ion mobility. A post-heat-treatment temperature of around 700 C is generally used to eliminate cation disorder, but little is known about these antisite defects or their concentration as a function of the post-heat-treatment temperature. In this study, time-resolved, synchrotron X-ray diffraction reveals that antisite defects are completely eliminated above 500 C, suggesting that the electrochemical performancemore » may be significantly enhanced by a milder postsynthesis heat treatment. The preliminary electrochemical results show a significant enhancement in the electrochemical capacity with the defect-free material, with the specific capacity increasing by approximately 60% at a C/20 rate.« less
  • A functional gradient material with eleven layers composed of a dental ceramics and titanium was successfully consolidated using field assisted sintering technique in a two-step sintering process. High energy X-ray diffraction studies on the gradient were performed at High Energy Material Science beamline at Desy in Hamburg. Phase composition, crystal unit edges and lattice mismatch along the gradient were determined applying Rietveld refinement procedure. Phase analysis revealed that the main crystalline phase present in the gradient is α-Ti. Crystallinity increases stepwisely along the gradient with a decreasing increment between every next layer, following rather the weight fraction of titanium. Themore » crystal unit edge a of titanium remains approximately constant with a value of 2.9686(1) Å, while c is reduced with increasing amount of titanium. In the layer with pure titanium the crystal unit edge c is constant with a value of 4.7174(2) Å. The lattice mismatch leading to an internal stress was calculated over the whole gradient. It was found that the maximal internal stress in titanium embedded in the studied gradient is significantly smaller than its yield strength, which implies that the structure of titanium along the whole gradient is mechanically stable. - Highlights: • High energy XRD studies of dental ceramics–Ti gradient material consolidated by FAST. • Phase composition, crystallinity and lattice parameters are determined. • Crystallinity increases stepwisely along the gradient following weight fraction of Ti. • Lattice mismatch leading to internal stress is calculated over the whole gradient. • Internal stress in α-Ti embedded in the gradient is smaller than its yield strength.« less
