"Clicking" functionality onto electrode surfaces

Feb 01, 2004 · Ferrocene immobilization correlates with azide disappearance. Cyclic voltammograms of mixed monolayers were taken after 0, 1, and 3 h of reaction (Figure 4).Electrochemically determined ferrocene coverages were 3.46 × 10 13 molecules/cm 2 after 1 h and 7.78 × 10 13 molecules/cm 2 after 3 h. 22 There was negligible change in the current peak after 3 h, providing further evidence that the

Furthermore, the closed system combined with small hold-up volumes offer an intrinsically safe environment for chemicals prone to explosive decomposition.Organic azides constitute such a compound class with potentially explosive properties. Christopher Chidsey's Profile Stanford ProfilesIn the presence of copper(I) catalysts, these azide-modified surfaces are shown to react rapidly and quantitatively with terminal acetylenes forming 1,2,3-triazoles, via "click" chemistry. The initial azide substituents can be identified and monitored using both grazing-angle infrared (IR) and X-ray photoelectron spectrosopies.

Evan Reed's Profile Stanford Profiles

Here we perform the first atomistic simulation of an azide energetic material, HN3, from the beginning to the end of the chemical evolution and find that the time scale for complete decomposition is a mere 10 ps, orders of magnitude shorter than that of secondary explosives and approaching the fundamental limiting time scale for chemistry; i.e Inhibiting platelet-stimulated blood coagulation by Feb 14, 2012 · Platelets are important mediators of blood coagulation that lack nuclei, but contain mitochondria. Although the presence of mitochondria in platelets has long been recognized, platelet mitochondrial function remains largely unaddressed. On the basis of a small amount of literature that suggests platelet mitochondria are functional, we hypothesized that the inhibition of platelet

Integrated structural biology and molecular ecology of N

Jul 05, 2017 · Abstract. In this paper, knowledge of the molecular ecology and environmental determinants of ammonia-oxidizing organisms is critical to understanding and predicting the global nitrogen (N) and carbon cycles, but an incomplete biochemical picture hinders in vitro studies of N-cycling enzymes. Although an integrative structural and dynamic characterization at the atomic scale would Model Studies of Azide Binding to Functional Analogues of N3 binding to a functional model of CcO is investigated in its Fe3+, Fe3+Cu+, and Fe3+Cu2+ forms. A combination of EPR and FTIR indicates that N3 binds in a bridging mode in the bimetallic sites and signature N3 bands are identified for several forms of N3 binding to the site. The presence of the distal metal increases the binding affinity of N3.
