Surface-Induced Dissociation Kinetics
ثبت نشده
چکیده
The research is designed to improve measurement of fast fragmentation kinetics of surface activated ions, to improve our understanding of how ions fragment and how energy transfers in collisions of ions with surfaces. A new technique, silicon nano-particle assisted laser desorption/ionization (SPALDI), was developed recently and allowed investigation of the kinetics of surfaceinduced dissociation (SID) of small molecules. A Bruker Proflex MALDI TOF and peak shape analysis model are used to investigate fast fragmentation of ions.

The implementation of surface-induced dissociation (SID) to study the fast dissociation kinetics (sub-microsecond dissociation) of peptides in a MALDI TOF instrument has been reported previously. Silicon nanoparticle assisted laser desorption/ionization (SPALDI) now allows the study of small molecule dissociation kinetics for ions formed with low initial source internal energy and without MALDI...
متن کاملThe formate and redox mechanisms of water-gas shift reaction on the surface of Ag: A nanocluster model based on DFT study
Two different possible mechanisms of water gas shift reaction including formate and redox mechanisms on the Ag5 cluster were investigated using DFT computations. All the elementary steps involved in both mechanisms were considered. It was observed that dissociation of H2Oads and OHads, as well as formation of CO2(ads), required activation e...
متن کاملDynamic surface site activation: a rate limiting process in electron beam induced etching.
We report a new mechanism that limits the rate of electron beam induced etching (EBIE). Typically, the etch rate is assumed to scale directly with the precursor adsorbate dissociation rate. Here, we show that this is a special case, and that the rate can instead be limited by the concentration of active sites at the surface. Novel etch kinetics are expected if surface sites are activated during...
متن کاملA Rough Energy Landscape to Describe Surface-Linked Antibody and Antigen Bond Formation
Antibodies and B cell receptors often bind their antigen at cell-cell interface while both molecular species are surface-bound, which impacts bond kinetics and function. Despite the description of complex energy landscapes for dissociation kinetics which may also result in significantly different association kinetics, surface-bound molecule (2D) association kinetics usually remain described by ...
متن کاملKinetics and mechanism of dissociation of cooperatively bound T4 gene 32 protein-single-stranded nucleic acid complexes. 1. Irreversible dissociation induced by sodium chloride concentration jumps.
The dissociation kinetics of cooperatively bound bacteriophage T4 gene 32 protein from a variety of single-stranded homopolynucleotides has been investigated by stopped-flow techniques. Irreversible dissociation of the complexes was induced by rapidly increasing the salt concentration and monitoring the increase in tryptophan fluorescence upon dissociation of the gene 32 protein. The dependence...
