The cichlid fish radiations of the African Great Lakes are an important model for evolutionary biology. Cichlids have diverse colour vision systems and predominately express three cone visual pigments. However, rare populations of spectrally distinct cones have been found in a number of species, but it is not known whether they contribute to spectral sensitivity. Adult Nile tilapia, Oreochromis...

A wavelength-switchable microlaser can be easily fabricated using environment-sensitive aggregation-induced emission luminogens (AIEgens) as the optical gain material.

Abstract We performed a time-resolved spectroscopic study of the VUV/UV scintillation gaseous argon as function pressure and electric field, by means wavelength sensitive detector operated with different radioactive sources. Our work conveys new evidence distinctive features light which are in contrast general assumption that, for particle detection purposes, can be considered to largely monoch...

To our knowledge, we have developed a novel temperature-jump optical tweezers setup that changes the temperature locally and rapidly. It uses a heating laser with a wavelength that is highly absorbed by water so it can cover a broad range of temperatures. This instrument can record several force-distance curves for one individual molecule at various temperatures with good thermal and mechanical...
