Ni(CN) 2 -CN-] n with trans-positioned bridging cyanide ligands in both cation and anion. The water molecules of crystallization are located between the chains and link them by hydrogen bonds. In the crystal structure of 4 the chains are built up of [Ni(cyclam)] 2+ cations linked by cyanide anions solely; as a consequ…
The purpose of the present work is to reveal around Kikuchi lines the temperature diffuse scattering maximums which, to our knowledge, have not been observed before. As specimen for investigations were single crystalline silicon films prepared by chemical etching of bulk crystals. The transmission electron diffraction…

Although Complex Metallic Alloy phases (CMAs) are known since the beginning of the last century, they have long been considered as rare and special cases of intermetallic compounds.Recent phase diagram studies using state of the art techniques have shown that CMAs occur frequently not only in multinary but also in bin…
Raman microscopy is having increasing applications into molecular biology. Primary structure features can be analyzed, such as Se-Met labeled protein crystals to be used for MAD crystallography Secondary structure modification can be clearly identified according to relationships between amide band frequencies and Rama…
A fluocerite (Ce,La)F3 single crystal intergrown with bastnaesite (Ce,La)[CO3]F from the Pikes Peak area in Colorado, USA was prepared for the investigation of the crystallographic orientation relationship between the two mineral phases via transmission electron microscopy.The epitactical overgrowth of bastnaesite on…
It is well known that metal dusting is an undesirable corrosion phenomenon that can be observed in a wide range of chemically and petrochemically working industries.Due to strongly carburizing atmospheres, it leads to a decomposition of materials into metal particles and carbon.The aim of this work is to clarify open…
It is convenient to consider a change in the structure of crystalline material as a reason for remarkable modifications in its physical properties: a structural phase transition often results in the anomalous behaviour of macroscopic parameters in condensed matter. However, is it always true that a detected change in…
Odorants are low-boiling compounds such as esters, ketones or ethers [1].Their structures in the gas phase may be studied by microwave spectroscopy [2].Odorants are active in condensed phase, and hence their solid-state structures are of interest, too.In addition to in situ crystallization [3], one can imagine two alt…
TiO 2 (rutile modification), space group (136) P4 2 /mnm, carried out in the vicinity of the Ti-K absorption edge. The influence of oxygen vacancies on the anomalous scattering signal (see e.g. [2]) has been studied on a series of 10 x 10 x 1 mm 3 single crystal wafers of different vacancy concentrations obtained by a…

preferred orientation of the ferroelectric domains accompanied by a macroscopic polarization. In PZT highest piezoelectric response is found at the morphotropic phase boundary (MPB), separating a rhombohedral structure, in which the polarization is along the [111] c direction, from a tetragonal structure, in which the…

For many years computer processors have been getting faster, which has meant that by upgrading hardware, software would run faster without any modifications. This is now beginning to change. Processor speeds are reaching a plateau, so manufacturers have instead begun to increase the computation power available by addi…
M 4 X 4 molecular cages where M is a metal and X is an element of group 15, 16 or 17 are quite common All these cages have the cube geometry as found in the well known Fe 4 S 4 ferredoxins Here we report on the synthesis and the crystal structure of [AlZn( 4 -O)(O 2 CCF 3 ) 3 ] 4 (1). This exceptional compound was dis…
Multifunctional ferromagnetic shape memory Heusler Ni-Mn-Ga alloys are frequently characterized by structural modulation in martensitic phases.In particular, modulated martensitic phases, showing the higher magnetic field induced strain performance, are the most promising candidates for technological applications.Depe…
Page s131 on protein size, secondary structure and overall conformation will be presented. The characterization of the solution structure and oligomerization state of the Arabidopsis gamma subunit is novel and important contribution to studies on Gproteins providing insights also for the mammalian proteins [1]
Page s214 s214follows that the width of the diffraction maximum in reciprocal space is proportional to the square root of the dislocation density, however the shape of the maximum strongly depends on the correlation of dislocation positions.The results were compared with dislocation curves obtained from the standard a…
residual ash is enriched in silica and applied as a good adsorbent material for heavy metals The capture of carbon dioxide and other smoke gases from the biomass burning can be vitally achieved through hot manganese oxide at 200-250 o C. The gases change the mineralogical composition of the applied manganese oxides or…
Dual Polarization Interferometry (DPI) is a waveguide based interferometer technique, which is well established for the characterisation of surface layers. This method allows the correlation of changes in refractive index to the thickness and density of surface layers immediately above a waveguide surface. It has ther…
