Monitoring Liquid Concentration Changes in Nanofluidic Channels Using Cross-Grating Wavefront Microscopy

Abstract Optical microscopy that employs intensity measurements of scattered, transmitted, or emitted light is critical to study micro- and nanofluidic systems widely used in, e.g., biology, chemistry, and materials science. Since such fluidic systems often are transparent, simpl...

Deciphering coccolith formation: advanced microscopy insights from the biomineralization of Gephyrocapsa huxleyi

Abstract Coccolithophores are unicellular marine phytoplankton that produce complex and intricately shaped mineralized scales called coccoliths. Coccoliths are produced in an intracellular vesicle where crystal nucleation occurs, from which several individual calcite units develo...

JuRa: The Juventas Radar on Hera Mission to Probe Internal Structure of Didymos and Dimorphos Asteroids

Abstract JuRa, the Juventas Radar, is the sounding radar of the Hera/ESA mission on cruise to the asteroid Didymos and its moon, Dimorphos. In 2027, it will, for the first time, do direct observation of the internal structure of an asteroid for the benefit of both science and pla...
