Wide-Bandgap Double Perovskites with Multiple Longitudinal-Optical Phonon Scattering
Alloyed lead-free double perovskites display intense photoluminescence, are environmentally friendly, and their devices show long-term operation. Thanks to these properties, which make them excellent warm...
Publikationen | 18.03.2022High-Resolution Kinoform X-Ray Optics Printed via 405 nm 3D Laser Lithography
Efficient focusing of X-rays is essential for high-resolution X-ray microscopy. Diffractive X-ray optics called kinoforms offer the highest focusing efficiencies in theory. However, they have long remained...
Publikationen | 18.03.2022Influence of non-Hermitian mode topology on refractive index sensing with plasmonic waveguides
We evaluate the sensing properties of plasmonic waveguide sensors by calculating their resonant transmission spectra in different regions of the non-Hermitian eigenmode space. We elucidate the pitfalls...
Publikationen | 18.03.2022Multispectral imaging flow cytometry for process monitoring in microalgae biotechnology
In the course of efficient development and optimization of biotechnological processes, the need for methods to track morphological and compositional changes of single cells is increasing. So far, the material...
Publikationen | 17.03.2022Super-resolution microscopy: a brief history and new avenues
Super-resolution microscopy (SRM) is a fastdeveloping field that encompasses fluorescence imaging techniques with the capability to resolve objects below the classical diffraction limit of optical resolution....
Publikationen | 15.03.2022Not that innocent – ammonium ions boost homogeneous light-driven hydrogen evolution
We report that the homogeneous light-driven hydrogen evolution reaction (HER) can be significantly enhanced by the presence of seemingly innocent ammonium (NH4 +) cations. Experimental studies with different...
Publikationen | 22.03.2022Evaluation of microbiome enrichment and host DNA depletion in human vaginal samples using Oxford Nanopore’s adaptive sequencing
Metagenomic sequencing is promising for clinical applications to study microbial composition concerning disease or patient outcomes. Alterations of the vaginal microbiome are associated with adverse pregnancy...
Publikationen | 10.03.2022Analysis of Low-Temperature Magnetotransport Properties of NbN Thin Films Grown by Atomic Layer Deposition
Superconducting niobium nitride (NbN) films with nominal thicknesses of 4 nm, 5 nm, 7 nm, and 9nm were grown on sapphire substrates using atomic layer deposition (ALD).We observed probed Hall resistance...
Publikationen | 10.03.2022A Combined Spectroscopic and Theoretical Study on a Ruthenium Complex Featuring a p-Extended dppz Ligand for Light-Driven Accumulation of Multiple Reducing Equivalents
The design of photoactive systems capable of storing and relaying multiple electrons is highly demanded in the field of artificial photosynthesis, where transformations of interest rely on multielectronic...
Publikationen | 11.03.2022Plasma Enhanced Atomic Layer Deposition of HfO2 with Substrate Biasing: Thin Films for High Reflective Mirrors
Tuning ion energies in plasma-enhanced atomic layer deposition (PEALD) processes enables fine control over the material properties of functional coatings. The growth, structural, mechanical, and optical...
