The main aim of the study was to determine chemical, optical and physical characteristics of aerosol particles responsible for visibility degradation in Yosemite National Park. The park, located in the central Sierra Nevada range in eastern California, was impacted by smoke from wildfire activity in the western United States. Determining the contribution made by smoke to visibility degradation ...

UV patternable high refractive index inorganic–organic hybrid materials prepared by sol–gel process can be nanoimprinted in order to get photonic crystal nanopatterns. Non-hydrolytic sol–gel process can make a UV curable and relatively high refractive index hybrid material, which can be cured without a significant shrinkage for nanoimprinting. Sol–gel process of heterogeneously functionalized s...

Because the refractive index of hemoglobin in the visible range is sensitive to the hemoglobin concentration, optical investigations of hemoglobin are important for medical diagnostics and treatment. Direct measurements of the refractive index are, however, challenging; few such measurements have previously been reported, especially in a wide wavelength range. We directly measured the refractiv...
