Graph Chatbot
Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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.
Current proteomic strategies depend strongly on the development of analytical methodologies and instrumentation. In parallel to the development of mass spectrometry (MS) - based proteomic workflows, microfluidic devices emerged in this field as a flexible ...
This paper presents the fabrication and operation of an integrated nano-electrospray thruster consisting of an array of microfabricated silicon capillary emitters and microfabricated silicon extractor electrodes. Based on previous work in which we showed o ...
Metal ions are essential elements in all living systems. Their detections and identifications in biological processes require different methodologies. Mass spectrometry is one of the commonly used techniques in bioinorganic analyses to fulfill these requir ...
The present work shows that the electrochemical properties of electrospray ionization (ESI) can be used to add functions to the process. As example, we show how the choice of the electrode material can be used to study interactions between metal ions and b ...
Cysteine-containing peptide oxidation was studied both by using an inert platinum electrode and a sacrificial electrode (copper or zinc) generating metallic ions in electrospray ionization mass spectrometry (ESI-MS). Using peptides containing one, two and ...
Nanoelectrosprays, well known for their use in sample injection for the mass spectrometry of large biomolecules, can also be used in other applications such as spacecraft propulsion. The thrust generated by a single electrospray emitter is well below 1 μN, ...
Electrospray ionisation (ESI) is a soft technique used in mass spectrometry (MS) analysis able to introduce a wide variety of analytes in the gas phase. Briefly, it consists in the application of a high- voltage to a solution to spray it through a small or ...
Ionic liquids pose challenges and provide solutions for electrospray ionisation mass spectrometry (ESI-MS). Being inherently charged, they are themselves easy to characterise in both positive- and negative-ion mode by ESI-MS, but the challenge arises when ...

In order to fully characterize the performance of the colloid thruster system the electrospray (ES) beam must itself be fully characterized. This may be achieved by measuring various properties such as flow rate, current, droplet/ion charge to mass ratio a ...
Electrospray ionisation mass spectrometry was used to analyze the reactions of metal compds. with mixts. of selected proteins. Three representative medicinally relevant compds., cisplatin, transplatin and the organometallic ruthenium compd. RAPTA-C, were r ...
