Electron transfer in two and three dimensions
No full textA number of osmium bipyndyl complexes have been synthesised and characterised using spectroscopic, chromatographic and electrochemical techniques. The complexes formed are [Os(bpy)2 4-tet C1]C104, [Os(bpy)2 4-bpt C1]PF6 and [Os(bpy)2 Cl 4-bpt Os(bpy) 2 C1](PF6)2, where bpy is 2 ,2 ’-bipyridyl, 4-tet is 3,6-bis(4-pyndyl)-l,2,455-tetrazine and 4- bpt is 3,5-bis(pyridin-4-yl)-l,2,4-tnazole Monolayers of [Os(bpy) 2 4-tet C1]C1 0 4 have been formed by spontaneous adsorption onto clean gold microelectrodes. The tetrazine bridge between the [Os(bpy)2Cl]+ head group and the metal electrode surface undergoes a reversible protonation/deprotonation reaction depending on the pH of the contacting electrolyte solution High speed cyclic voltammetry reveals that the redox switching mechanism is best described as a non-adiabatic, through-bond tunnelling mechanism Significantly, while protonating the bridging ligand does not influence the free energy of activation, 10 3±1 1 kJ mol *, k° decreases by 1 order of magnitude from 1 1 x 104 s 1 to 1 2 x 103 s 1 upon going from a deprotonated to a protonated bridge. These observations are interpreted in terms of a through-bond tunnelling mechanism m which protonation decreases the electron density on the bridge and reduces the strength of electronic coupling between the redox centre and the electrode.
Solid deposits of the dimeric complex [Os(bpy) 2 Cl 4-bpt Os(bpy)2 C1](PF6)2 have been deposited on platinum microelectrodes by mechanical attachment. The electrochemical response exhibited by these deposits is unusually ideal over a wide range of electrolyte compositions and pH values Dct, the charge transport diffusion coefficient, is independent of the electrolyte concentration, indicating that electron self-exchange between adjacent redox centres limits the overall rate of charge transport through the solid In 1 0 M L1CIO4 and 1 0 M HCIO4, Dct values are 2 0±0 lxlO10 and 1 7±0 4x10 10 cm2 s corresponding to second order electron transfer rate constants of 18 x l07 and 3xl07 M 1 s 1. The standard rate of heterogeneous electron transfer across the electrode/deposit interface is 1 08+0 05x10 cm s. This value is approximately one order of magnitude lower than that found for a similar monomeric complex in which the bridging ligand is attached directly to the electrode surface, indicating that the 4-bpt ligand does not promote strong electronic communication between the [Os(bpy)2CI]+ head group and the electrode surface.
Monolayers of [Os(bpy)2 4-bptCl]PF6 have been formed by spontaneous adsorption onto platinum microelectrodes. These monolayers are extremely stable under a wide range of electrolyte compositions and pH values Significantly, the 4-bpt ligand is capable of undergoing a protonation/deprotonation reaction depending on the pH of the contacting electrolyte solution. High speed chronoamperometry reveals that protonation of the 4-bpt bridging ligand causes the standard rate of heterogeneous electron transfer to decrease by at least an order of magnitude from 2 67 x 106 to 4 5 x 104 s' 1 for the oxidation process and from 1 60 x 106 to 1 9 x 105 for the reduction process Consistent with a superexchange mechanism, these observation are interpreted in terms of a hole superexchange process, the rate of which decreases with increasing energy gap between the osmium metal dn orbitals and the highest occupied molecular orbital of the bridge

The Fantasies of E. M. Forster to Explore the Inner Self in His Short Stories
No full textForster has used fantasy as a technique with his characteristic ironic prose style combining poetry and symbolism. So it is necessary to define fantasy and examine its use as a fictional technique in general and E. M. Forster in particular because as Forster claims, most of his short stories are fantasies in form. With his characteristic ironical personal style, Forster has been able to explore his inner experiences, his self, through these fantasies, by using symbols and poetry in them, and by giving allegorical dimension to them. He also shows how this inner self confronts with the society of the world
Strategic Interaction in Pharmaceutical Price Regulation: With or Without U?
No full textWe study strategic interaction among countries in pharmaceutical price regulation resulting from innovation-related spillovers. In our theoretical model, regulators’ pricing decisions affect welfare both directly and indirectly, via firms’ R&D policies. We characterise two types of equilibrium, depending on whether countries price at, or above, the minimum level the industry is willing to accept to serve the market. The combination of these two equilibria may imply a U-shape relationship between countries’ pharmaceutical prices and relative market size. We find support for this hypothesis, using data for 83 cancer drugs in 23 OECD countries. Our results contribute to the academic debate about the relationship between prices and market size, as well as the policy debate about using supranational procurement policies to lower prices. In particular, we show that joint procurement can lower or raise prices according to the sizes of the domestic markets which join to create a single purchasing authority
A Dynamic Subfilter-scale Stress Model for Large Eddy Simulations Based on Physical Flow Scales
No full textWe propose a new definition of the length scale in an eddy-viscosity model for large-eddy simulations (LES). This formulation extends and generalizes a previous proposal [Piomelli, Rouhi and Geurts, Proc. ETMM10, 2014], in which the LES length scale was expressed in terms of the integral length-scale of turbulence determined by the flow characteristics and explicitly decoupled from the simulation grid; this approach was named Integral Length-Scale Approximation (ILSA). As in the original ILSA, the model coefficient was determined by the user, and required to maintain a desired contribution of the unresolved, subfilter scales (SFS) to the global transport. We propose a local formulation (local ILSA) in which the model coefficient is local in space, allowing a precise control over SFS activity as a function of location. This new formulation preserves the properties of the global model; application to channel flow and backward-facing step verifies its features and accuracy
