New Ba5(V2O7)2Cl2 was isolated by a high-temp. (850°) reaction employing a CsCl/RbCl flux. The structure was detd. by single crystal x-ray diffraction methods. This compd. crystallizes in an orthorhombic crystal system, space group Pmmn, with a 11.558(2), ...
Intercalates and exfoliates formed from layered materials and dendritic polymers are disclosed, together with the uses of these materials, e.g. in producing composite materials. The dispersion of layered materials in a dendritic polymer matrix (hyperbranch ...
Insight into the conformations and aggregation of alginic acid was gained by measuring its diffusion coefficient at very dilute concentrations using fluorescence correlation spectroscopy. Both the pH and ionic strength (I) had an important influence on the ...
The prototypal hexacoordinate C (phC) mol., CB62- (D6h), can be annulated by inserting arenes, olefins, or other one or two atom bridging groups into a perimeter B-B bond. Two single-atom units also can bridge opposite CB6 edges. These strategies allow the ...
The investigation of H-1-H-1 spin-diffusion build-up curves using a rate matrix analysis approach shows that high-resolution magic angle spinning NMR of protons, applied to powdered organic compounds, provides a method to probe crystalline arrangements. Th ...
The present study explores the potential use of asymmetrical flow field flow fractionation (aFlFFF) with a multidetection system for the study of metal–alginate interactions. aFlFFF, coupled on-line to a differential refractive index and seven angle laser ...
Here, the crystallization and initial phasing of the C-terminal domain of human KIN17, a 45 kDa protein mainly expressed in response to ionizing radiation and overexpressed in certain tumour cell lines, are reported. Crystals diffracting to 1.4 Å resolutio ...
In this work, the microstructure transition from amorphous to microcrystalline silicon is defined in terms of the silane concentration in the plasma as opposed to the silane concentration in the input gas flow. In situ Fourier transform infrared absorption ...
We show that no deterministic algorithm can solve consensus in the presence of t+1 process crash failures, in a system of n processes that communicate in a reliable way and synchronize their activities using any number of t-resilient services. These base s ...
ELMy H-modes in helium-4 plasmas provide valuable information on ELMy H-mode physics as well as a possible early low activation operational phase for next-step tokamaks, such as ITER. With this in mind, a series of helium-4 H-mode experiments were performe ...
