Total internal reflection microscopy is a light microscopy ... of the distance between the coverslip and a microscopic sphere. SPARXS couples single-molecule fluorescence microscopy with next ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

In a fluorescent OLED, only singlets decay radiatively through fluorescence with an ~ns exciton lifetime, which sets the theoretical limit of the internal ... Its reflection is fairly specular ...

Ray Optics: Reflection of light, spherical mirrors, mirror formula, refraction of light, total internal reflection and optical fibers, refraction at spherical surfaces, lenses, thin lens formula ...

In this work, we introduce an approach where these states are monitored in a total internal reflection (TIR) fluorescence microscope, via the characteristic variations of the time-averaged ...

Our group previously reported a sensitive and specific detection assay of miRNAs in single molecule level with the aid of total internal reflection fluorescence microscopy. In this work, we advanced ...

The OceanGate Disaster,” thrusts the ill-fated Titan submersible and its catastrophic end back into the global spotlight. The ...

Gelatin can be used for much more than a sweet treat. It can also act as a smoked lens—which allows you to view total internal reflection—or as a color filter. Prepare the red, blue, and clear gelatin ...

This phenomenon is called total internal reflection, because very nearly 100 percent of the beam is reflected, which is better than the very best mirror surfaces. The critical angle for water is ...

The internal quantum efficiency of OLED has been achieved near ... In results, optical energy of propagation wave is restricted only a half of the total emission energy. It is clear that the light out ...

Abstract: We report a novel sensor for label-free biomolecular assay using a one-dimensional photonic crystal in a total-internal-reflection geometry. This configuration creates a unique open ...
