Breaking the diffraction limit of light-sheet fluorescence microscopy by RESOLFT [PDF]

Proceedings of the National Academy of Sciences, 2016
Significance Light-sheet fluorescence microscopy (LSFM) is an imaging modality in which a sample is illuminated from the side by a beam engineered into a wide and relatively thin “sheet.” This allows highly parallelized planewise scanning of volumes with inherent optical sectioning, offering a good balance between spatial and temporal

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

A versatile oblique plane microscope for large-scale and high-resolution imaging of subcellular dynamics

eLife, 2020
We present an oblique plane microscope (OPM) that uses a bespoke glass-tipped tertiary objective to improve the resolution, field of view, and usability over previous variants. Owing to its high numerical aperture optics, this microscope achieves lateral

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

Advanced Materials, EarlyView.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems
