The induced aggregation of the xanthenedye rho-damineB (RhB) on metal oxide centers belonging to the highly symmetric surfaces of precise nanoscale templates with Keplerate (Mo 132 )o rtoroidal (Mo 138 )s tructures has been studied. With the joint use of the Langmuir isotherma nd full Stern-Volmer models, the thermodynamic reasons for dye adsorption on the nanocluster surface, such as amixture of monomer,H -aggregate (H-dimer), and J-aggregate forms (which can coexist or switch one into another under the exact conditions), were established:t his was shown through UV/Vis and fluorescence spectroscopies. By using the frame-work of the excitonm odel, it is shownt hat the angle( a)b etweent he transition dipole moments of RhB is very sensitive to surface strain inside the dye sub-monolayer.A saresult, it is possible to switch from H-to J-aggregates by the postfunctionalization of polyoxometalate (POM)-RhB associates by the surfactant bilayer shell, which allows the surface strain to grow.R ecommendations are provided for managing the appearance of H-or J-aggregates on metal oxide (or polyelectrolyte) surfacesd uring photovoltaico rb ioimaging applications.[a] V.

A three-objective multipass matrix system has been theoretically analyzed with respect to the aberrations of the third order. An expression has been derived in the three-dimensional coordinate system relating the position of a point in the output slit to that of a point in the input slit, depending on the construction peculiarities of the system given and the parameters of the matrix of intermediate images. Conditions of image focusing upon the input slit and astigmatism compensation have been derived. Relationships to determine the field curvature and distortion have been derived.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
