Super-resolution microscopy and studies of peroxisomes
Fluorescence microscopy is an important tool for studying cellular structures such as organelles. Unfortunately, many details in the corresponding images are hidden due to the resolution limit of conventional...
Publications | 08.02.2023Lateral Charge Migration in 1D Semiconductor-Metal Hybrid Photocatalytic Systems
Colloidal nanorods based on CdS or CdSe functionalized with metal particles have proven to be efficient catalysts for light driven hydrogen evolution. Seeded CdSe@CdS nanorods have shown increasing performance...
Publications | 01.02.2023Calculating Point Spread Functions: Methods, Pitfalls and Solutions
We discuss advantages and disadvantages of various ways of calculating an optical Point Spread Function (PSF) and present novel Fourier-based techniques for computing vector PSF. The knowledge of the exact...
Publications | 01.02.2023Spectromicroscopy Studies of Silicon Nanowires Array Covered by Tin Oxide Layers
The composition and atomic and electronic structure of a silicon nanowire (SiNW) array coated with tin oxide are studied at the spectromicroscopic level. SiNWs are covered from top to down with a wide...
Publications | 25.01.2023Characterization of PVL-Positive MRSA Isolates in Northern Bavaria, Germany over an Eight-Year Period
Purpose: Community-acquired methicillin-resistant Staphylococcus aureus strains (CAMRSA) are spread worldwide and often cause recurring and persistent infections in humans. CAMRSA strains frequently carry...
Publications | 23.01.2023Single-step post-production treatment of lead acetateprecursor-based perovskite using alkylamine salts forreduced grain-boundary related film defect
Powered by the worldwide efforts of research groups experienced in dye-sensitized, and thin-film solar cells, perovskite solar cells (PSCs) reached apower conversion efficiency of 25.7% within 10 years....
Publications | 16.01.2023Nanostructured Silicon Matrix for Materials Engineering
Tin-containing layers with different degrees of oxidation are uniformly distributed along the length of silicon nanowires formed by a top-down method by applying metalorganic chemical vapor deposition....
Publications | 06.02.20233D-nanoprinted on-chip antiresonant waveguide with hollow core and microgaps for integrated optofluidic spectroscopy
Here, we unlock the properties of the recently introduced on-chip hollow-core microgap waveguide in the context of optofluidics which allows for intense light-water interaction over long lengths with fast...
Publications | 17.01.2023Temperature-Sensitive Dual Dispersive Wave Generation ofHigher-Order Modes in Liquid-Core Fibers
The emission of resonant radiation from temporal solitary waves—also known as dispersive wave generation—allows efficient energy transfer to far-distant spectral domains. This coherent radiation can...
Publications | 11.01.2023Advanced fiber in-coupling through nanoprinted axially symmetric structures
Here, we introduce and demonstrate nanoprinted all-dielectric nanostructures located on fiber end faces as a novel concept for the efficient coupling of light into optical fibers, especially at multiple...
