Aluminum zinc alloys constitute an important class of wrought alloys, the so-called 7000 series, and are also widely used as anti-corrosion coatings of steel sheets. They are also interesting from a more fundamental point of view because zinc, a hexagonal ...
The microstructure of a Co38Ni33Al29 ferromagnetic shape memory alloy was determined by conventional transmission electron microscopy (TEM), electron diffraction studies together with advanced microscopy techniques and in situ Lorentz microscopy. Rod-like ...
In order to obtain a sensor with force resolution better than 100 pN for biomolecular detection, U-shaped piezoresistive cantilevers made of crystalline silicon have been fabricated. The resistors have been defined by ionic implantation of As+, yielding a ...
Standard theta-2 theta and pole figure X-ray diffraction techniques were used to study structural properties and preferred orientation of nanostructured TiAIN thin films prepared using cathodic are deposition. Systematic collection of reflections from latt ...
The hydroxylated surface structures of seven morphologically important crystallographic surfaces of hematite were calculated allowing the determination of the surface energies and, consequently,the hematite equilibrium morphology. The docking of two organi ...
We describe a highly effective method of reducing thermal sensitivity in piezoresistive sensors, in particular silicon cantilevers, by taking advantage of the dependence of the piezoresistive coefficient of silicon on crystallographic orientation. Two simi ...
The transition metal tellurium oxychloride, Ni-5(TeO3)(4)Cl-2, has been investigated by high-field electron-spin resonance for frequencies up to 3 THz, at temperatures well below the magnetic ordering at 23 K. At zero external field several resonance modes ...
Electron crystallography determines the structure of membrane proteins and other periodic samples by recording either images or diffraction patterns. Computer processing of recorded images requires the determination of the reciprocal lattice parameters in ...
Objective. Mechanism of calcification of cardiac valves was investigated through a comparative characterization of structure, morphology, and size of hydroxyapatite (HAP) crystals formed in mineral deposit on cardiac valves, bone tissue, and crystals synth ...
Maximum likelihood (ML) processing of transmission electron microscopy images of protein particles can produce reconstructions of superior resolution due to a reduced reference bias. We have investigated a ML processing approach to images centered on the u ...
