AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The present study reports on the synthesis of nanocrystalline (K-x,Na1-x)NbO3 powders prepared via microemulsion mediated hydrolytic decomposition of mixed alkoxide solutions. Compositions with different K/Na ratios ranging between the two end members KNbO ...
The reaction of [ReBr3(CO)(3)]NEt4 with 3-hydroxy-1,2,3-benzotriazine-4 (3 H) -one in the presence of base gave the ionic rhenium complex [ReBr(C7H4N3O2)(CO)(3)][NEt4] (2) which was crystallographically characterized. A neutral metallamacrocycle 3 was ...
A series of tridentate benz- ACHTUNGTRENUNGimidazole-substituted pyridine-2-carboxylic acids have been prepared with a halogen, methyl or alkoxy group in the 6-position of the benzimidazole ring, which additionally contains a solubilising N-alkyl chain. Th ...
The preparation of single crystals suitable for X-ray analysis is frequently the most difficult step in structural studies of proteins.With the aid of two examples, it is shown that de novo solution of the crystallographic phase problem can be achieved at l ...
The transformation of pyroxene to its high-pressure polymorph akimotoite (MgSiO3 ilmenite type structure) is documented in the shock-induced melt veins of the L6 Tenham chondrite. Four textural relationships between pyroxene and akimotoite are observed in ...
A protein crystallography experiment at the xenon K-edge (lambda = 0.358 Angstrom) has been successfully carried out at the materials science beamline (BL2/ID11) of the ESRF. The samples used in this methodological study were crystals of porcine pancreatic ...
X-ray induced anisotropic variations of cell parameters in porcine pancreatic elastase (PPE) were used in a multi-Pawley refinement in order to improve the deconvolution of overlapping peaks occurring in the high-angle region of the powder pattern. The ben ...
The hollandite high-pressure polymorph of plagioclase has been identified in shock-induced melt veins of the Sixiangkou 16 chondrite. It is intimately intergrown with feldspathic glass within grains previously thought to be "maskelynite." The crystallograp ...
We investigate the presence of secondary phases in La-doped Bi-2201 thin films grown by laser ablation. The cation ratios in the target material, the oxygen pressure, and the substrate temperature during the deposition are the main parameters determining t ...
We have studied deposition by in-situ reactive sputtering of ferroelectric Pb(ZrxTi1-x)O3 (PZT) thin films on Pt and RuO2 electrodes, using temperatures in the 490-620°C range. Nucleation on the electrode was found to be of prime importance for the formati ...
