Identifying site-dependent reactivity in oxidation reactions on single Pt particlesCatalytic nanoparticles are heterogeneous in their nature and even within the simplest particle various surface sites exist and
The location of the absorption edge for ZnNC reveals that the oxidation state of the Zn atom is between 0 and + 2. The Fourier-transformed (FT) k3-weighted EXAFS spectrum of ZnNC exhibits a main peak at around 1.47 Å, corresponding to Zn-N coordination. The possibility of Zn...
(SPM; Pepelnik et al., 2004), hypoxia (BFG, 2008), increased current or changes in oxidation/reduction potential and pH-conditions (Calmano et al., 1993)) it is obvious that the reactions will differ significantly from those of biota exposed under standardized laboratory conditions (Mesa, ...
(Supplementary Fig.6). As Ru in the dimer structure can adsorb and desorb O more easily through an oxidation–reduction process than Pt, the CV curve in Supplementary Fig.6bexhibited a weak O adsorption/desorption peak. Figure4ashows the HER curves of the catalysts, which were measured by ...

and the second one located at ~2.45 Å could be ascribed to neighboring cobalt metals (that is, Co–Co) surrounding the absorbing Co ions. The shorter Co-O and Co-Co paths over those of Co(OH)2agree well with the full oxidation of Co(OH)2. The absence of the Co-Co path ...
value obtained from a random group of subjects, a value lower than the control may be indicative of responsiveness to therapy. Where the method is intended to monitor patients during therapy to establish whether they are responding to therapy, a reduction in marker protein expression during therapy...
With reference to Table 2, there was a thunderstorm on 19 July that likely explains the sudden reduction in PM2.5 concentration due to aerosol "wash-out" on this day com- pared to the preceding and following days. Figure 6 shows a fugitive dust event on 23 August, which is characterised ...
Once initial fragmentation occurs, enzymes involved in demethylation and ring cleavage, oxidation of aromatic and aliphatic moieties, and subsequent fermentation and methanogenesis pathways become involved. It is believed that microorganisms present in hydrocarbon-bearing formations, including methanogens, are ...
