The mesoglea buffers the physico-chemical microenvironment of photosymbionts in the upside-down jellyfish Cassiopea sp.
Anders Meibom, Niclas Heidelberg Lyndby, Michael Kühl
IntroductionThe jellyfish Cassiopea has a conspicuous lifestyle, positioning itself upside-down on sediments in shallow waters thereby exposing its photosynthetic endosymbionts (Symbiodiniaceae) to light. Several studies have shown how the photosymbionts b ...
FRONTIERS MEDIA SA2023Towards a Framework for Light-Dosimetry Studies: Methodological Considerations
Marilyne Andersen, Steffen Lutz Hartmeyer, Forrest Simon Webler
For field research of non-visual effects of light, accurate measurement of personal light exposure is required. A consensus framework for light-dosimetry could improve non-visual field research and ensure comparability between studies. Here we present a re ...
Commission Internationale de L'Eclairage (CIE)2021All-Dielectric Programmable Huygens' Metasurfaces
Hatice Altug, Andreas Tittl, Aleksandrs Leitis
Low-loss nanostructured dielectric metasurfaces have emerged as a breakthrough platform for ultrathin optics and cutting-edge photonic applications, including beam shaping, focusing, and holography. However, the static nature of their constituent materials ...
WILEY-V C H VERLAG GMBH2020Exciton, Biexciton, and Hot Exciton Dynamics in CsPbBr3 Colloidal Nanoplatelets
Jacques-Edouard Moser, Etienne Christophe Socie, Andrés Burgos Caminal, Brener Rodrigo De Carvalho Vale
Lead halide perovskites have emerged as promising materials for light-emitting devices. Here, we report the preparation of colloidal CsPbBr3 nanoplatelets (3 × 4 × 23 nm3) experiencing a strong quasi-one-dimensional quantum confine- ment. Ultrafast transie ...
2020Elucidating the role of the InGaN UL in the efficiency of InGaN based light-emitting diodes
Blue III-nitride light-emitting diodes (LEDs) are widely used nowadays in solid-state lighting, as white light can be produced by combining yellow phosphors and blue LEDs. This technology has the advantage to have a higher luminous efficiency than incandes ...
