The interplay of screw dislocations with carbon atoms is investigated in tungsten at high temperature using situ straining experiments a transmission electron microscope (TEM) and through ab initio calculations. When the enough to activate diffusion, above 1373 K, segregates core modifies their mobility, even for concentration as low 1 appm. TEM observations reveal reappearance Peierls mechanis...

The title compound, C(30)H(25)NOP(2), is a bulky phosphazene derivative. Its previous crystal structure [Cameron et al. (1979 ▶). Acta Cryst. B35, 1373-1377] is confirmed and its H atoms have been located in the present study. The formal P=N double bond is about 0.05 Å shorter than the P-N single bond and the large P=N-P bond angle reflects the steric strain in the mol-ecule. An intra-molecular...

High-throughput measurement using the numerical inverse method combined with the diffusion multiple technique was employed to determine the composition-dependent interdiffusion coefficients in fcc Al–Co–Cr–Fe–Ni high-entropy alloys at 1273, 1323, and 1373 K. The reliability of the obtained interdiffusion coefficients was confirmed by comparing the model-predicted composition/interdiffusion flux...

This article reports the molecular diagnosis findings regarding chronic myeloproliferative neoplasms made in a Molecular Biology Laboratory over a seven years’ experience (between 2009 and 2015). Ritus Biotec ltd is an ELN (European Leukemia Net) certified diagnostic laboratory for quantification of BCR-ABL. 1373 patients were subjected to Jak2 V617F testing in this time frame. The patients wer...

Stein’s method provides a way of bounding the distance of a probability distribution to a target distribution μ. Here we develop Stein’s method for the class of discrete Gibbs measures with a density e , where V is the energy function. Using size bias couplings, we treat an example of Gibbs convergence for strongly correlated random variables due to Chayes and Klein [Helv. Phys. Acta 67 (1994) ...

Mixed holmium cobaltite-chromite HoCo0.5Cr0.5O3 with orthorhombic perovskite structure (structure type GdFeO3, space group Pbnm) was obtained by solid state reaction of corresponding oxides in air at 1373 K. Room- and high-temperature structural parameters were derived from high-resolution X-ray synchrotron powder diffraction data collected in situ in the temperature range of 300-1140 K. Analys...

Tracer diffusion of the substitutional components in interstitial (CoCrFeNiMn)1-xCx high-entropy alloys with nominally x = 0.002, 0.005 and 0.008 (in at. fractions) is measured at elevated temperatures from 1173 to 1373 K. Two different characteristic effects carbon addition on these FCC are distinguished. At highest temperature K, alloying by C relatively low concentrations (x 0.002) retards e...
