Advanced electroanalytical chemistry at nanoelectrodes
Nanoelectrodes, with dimensions below 100 nm, have the advantages of high sensitivity and high spatial resolution. These electrodes have attracted increasing attention in various fields such as single cell analysis, single-molecule detection, single particle characterization and high-resolution imaging. The rapid growth of novel nanoelectrodes and nanoelectrochemical methods brings enormous new...
متن کاملRandall-Sundrum with AdS(7)
In the same sense that AdS5 warped geometries arise naturally from Type IIB string theory with stacks of D3 branes, AdS7 warped geometries arise naturally from M theory with stacks of M5 branes. We compactify two spatial dimensions of AdS7 to get AdS5 ×Σ 2, where Σ2 is e.g. a torus T 2 or a sphere S2. The metric for Σ inherits the same warp factor as appears in the AdS5. Bulk fields generically...
متن کاملAdult vernier thresholds do not increase with age; vernier bias does.
Vernier acuity and vernier bias were examined in persons aged 20 to 79 years using a method of adjustments. Vernier bias (mean error) showed a sharp increase between 35 and 45. Vernier acuity (standard deviation or precision of alignment) did not vary significantly with age. These different results indicate the importance of separate evaluation of acuity and bias. Vernier acuity is little affec...
متن کاملVernier-Templated Synthesis, Crystal Structure, and Supramolecular Chemistry of a 12-Porphyrin Nanoring
Vernier templating exploits a mismatch between the number of binding sites in a template and a reactant to direct the formation of a product that is large enough to bind several template units. Here, we present a detailed study of the Vernier-templated synthesis of a 12-porphyrin nanoring. NMR and small-angle X-ray scattering (SAXS) analyses show that Vernier complexes are formed as intermediat...
متن کاملVariation in vernier acuity with age
Many visual functions deteriorate with increasing age, vernier acuity apparently being an exception. We used an improved experimental protocol to investigate vernier thresholds in subjects in four age groups. Vernier threshold was found to increase with increasing age, and the difference in this, compared with previous findings is probably due to the smaller inter-pixel angle used. Vernier acui...
