On the structure of grain/interphase boundaries and interfaces
Beilstein J. Nanotechnol. 2014, 5, 1603–1615, doi:10.3762/bjnano.5.172
- difficult, slightly defective material boundaries are often modeled by treating the entire boundary as planar and by using the concepts of crystallography. For highly disordered boundaries, a description in terms of a representative volume, made up of a non-crystalline basic unit or a combination of such
- symmetry of atomic arrangements. There are also properties that critically depend on defects and their distribution in materials. For explaining at least some of the latter class of properties, ideas based on geometry/crystallography are only of limited use [1]. At the other extreme is the notion of
- to be planar and understanding the responses of the boundaries to external stimuli by using notions based in crystallography. This covers all kinds of crystalline grain boundaries, excluding random high-angle grain boundaries. Here two alternative approaches are found: (i) a purely geometrical
Spin relaxation in antiferromagnetic Fe–Fe dimers slowed down by anisotropic DyIII ions
Beilstein J. Nanotechnol. 2013, 4, 807–814, doi:10.3762/bjnano.4.92
- be varied between 3.0 and 300 K. X-Ray crystallography: Data were measured on Stoe IPDS II (1) or IPDS I (2) image plate diffractometers using graphite-monochromated Mo Kα radiation, and were corrected for polarisation and absorption. Structure solution (direct methods) and full-matrix least-squares
Grain boundaries and coincidence site lattices in the corneal nanonipple structure of the Mourning Cloak butterfly
Beilstein J. Nanotechnol. 2013, 4, 292–299, doi:10.3762/bjnano.4.32
- detail and from a crystallography/defect-structure point of view. The results of this investigation will be published shortly [10]. Briefly, this study has shown that the highly ordered hexagonal structure is made up of nipples with average diameters on the order of 150 nm and a unit cell lattice
Imaging ultra thin layers with helium ion microscopy: Utilizing the channeling contrast mechanism
Beilstein J. Nanotechnol. 2012, 3, 507–512, doi:10.3762/bjnano.3.58
- , light adlayers on heavy substrates can be imaged. We emphasize that this contrast mechanism is purely based on changes in the crystallography of the sample. Apart from the detection of ultrathin adlayers, this mechanism therefore also has the potential to reveal crystal defects, such as dislocations or
Channeling in helium ion microscopy: Mapping of crystal orientation

- images. Secondary electron images can be used to extract crystallographic information from bulk samples as well as from thin surface layers, in a straightforward manner. Keywords: channeling; crystallography; helium ion microscopy; ion scattering; Introduction The superior resolution of the helium ion
- contain information on the bulk crystallography. The achievable information depth will depend on acceleration voltage and elemental composition of the specimen. However, for gold at 20 keV it is of the order of a few tens of nanometers, and consequently higher than the SE information depth of 2 nm to 3 nm
Self-organizing bioinspired oligothiophene–oligopeptide hybrids
Beilstein J. Nanotechnol. 2011, 2, 525–544, doi:10.3762/bjnano.2.57
- progress in our understanding of the principles of fibril formation has been made owing to numerous experimental and theoretical studies and, importantly, the resolution of peptide arrangements at the atomistic level by means of X-ray crystallography and solid-state NMR [4][5][6]. The outstanding ability
Characterization of protein adsorption onto FePt nanoparticles using dual-focus fluorescence correlation spectroscopy

- observed, strongly suggesting the formation of protein monolayers that enclose the nanoparticles. Consistent with this interpretation, the absolute increase in hydrodynamic radius can be correlated with the molecular shapes of the proteins known from X-ray crystallography and solution experiments
- -density lipoprotein (HDL) and plays an essential role in lipid transport and metabolism. This protein has a molecular mass of 28 kDa. X-ray crystallography revealed a two-domain structure, with a N-terminal domain forming a four-helix bundle and a structurally less well organized C-terminal domain (Figure
