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 electrochem. oxidns. of some org. compds. have shown that only reactions involving simple electron transfer are active on diamond electrodes in the potential region of water stability. For more complex reactions, diamond electrodes show no electrocatal ...
Aerolysin is secreted as an inactive dimeric precursor by the bacterium Aeromonas hydrophila. Proteolytic cleavage within a mobile loop near the C terminus of the protoxin is required for oligomerization and channel formation. This loop contains the sequen ...
A procedure is described whereby the performance of NMR pulse expts. which use fixed free precession periods with durations that should be matched to the reciprocal of a scalar, dipolar, or quadrupolar coupling const. or a resonance offset can be made less ...
We present the first X-ray secondary (photoelectron) emission microscopy (XSEM) pictures and video microimages of an uncoated and unstained neuron specimen. This novel kind of synchrotron radiation microscopy is suitable for local chemical analysis with a ...
The results are given of an extensive structural study of Na13, Mg13, Al13, and Si13 carried out with the Car-Parrinello method. Several and mostly unforeseen noncryst. structures are discovered to characterize the low portion of the potential energy surfa ...
The analytical modeling and simulation of conservative electrostatic, electromagnetic and electrodynamic transducers found in microsystems using a non-linear lumped-parameter approach is presented in this paper. A comparison is made between this approach a ...
The microscopic description of the interface of colloidal particles in solution is essential to understand and predict the stability of these systems, as well as their chemical and electrochemical reactivity. However, this description often relies on the u ...
