We give a process calculus model that formalizes a well known algorithm (introduced by Chandra and Toueg) solving consensus in the presence of a particular class of failure detectors (Diamond S); we use our model to formally prove that the algorithm satisf ...
The concept of non-diamond sp2 impurity states as charge transfer mediators on boron-doped diamond (BDD) surface was suggested as an explanation for the electrochem. behavior of synthetic diamond-based electrodes. To verify this concept, graphite particles ...
We provide a novel model to formalize a well-known algorithm, by Chandra and Toueg, that solves Consensus among asynchronous distributed processes in the presence of a particular class of failure detectors (Diamond S or, equivalently, Omega), under the hyp ...
Diamond/metal composites with diamond contents between 57 and 72 vol% have been produced by gas pressure assisted liquid metal infiltration using Ag-3 wt% Si and Al-2 wt% Cu as matrix. The experimental data cover a range of Young's moduli from 300 to 425 G ...
GaN epilayers are grown on (111) oriented single crystal diamond substrate by ammonia-source molecular beam epitaxy. Each step of the growth is monitored in situ by reflection high energy electron diffraction. It is found that a two-dimensional epitaxial w ...

We study by means of ab initio calculations the ideal tensile and shear strengths of the C-46 clathrate phase. While its bulk modulus and elastic constants are smaller than in diamond, its strength is found to be in all directions larger than the critical ...
A heat sink that is particularly suitable for semiconductor components is made from a diamond-containing composite material. In addition to a diamond fraction amounting to 40-90% by volume, the composite material also contains 7 to 59% by volume copper or ...
Mineral inclusions in Sao Luiz diamonds have been characterized using angle dispersive X-ray diffraction and Raman spectroscopy. We identified two different garnet phases coexisting with an omphacitic pyroxene. They represent disintegration products of a f ...
Reflected-light microscopy and fine-scale lasts microRaman spectroscopy of shocked garnet-cordierite-sillimanite gneisses in suevites of the Ries meteorite impact crater, Germany, led to the discovery of impact diamonds in their pristine graphite-diamond a ...
