Single-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....
Publikationen | 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....
Publikationen | 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...
Publikationen | 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...
Publikationen | 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...
Publikationen | 11.01.2023Experimental Realization of a 12,000-Finesse Laser Cavity based on a Low-Noise Microstructured Mirror
The most precise measurement tools of humankind are equipped with ultra-stable lasers. State-of-the-art laser stabilization techniques are based on external cavities, that are limited by noise originated...
Publikationen | 24.01.2023Label-Free Characterization of Macrophage Polarization Using Raman Spectroscopy †
Macrophages are important cells of the innate immune system that play many different roles in host defense, a fact that is reflected by their polarization into many distinct subtypes. Depending on their...
Publikationen | 10.01.2023Histone demethylase KDM4C prevents cellular senescence in JAK2-mutated neoplasms
Background: JAK2 V617F mutations are associated with myeloproliferative neoplasms (MPN). Current therapeutic options are ineffective to eradicate JAK2-mutated clones. Hence, MPN patients are at risk of...
Publikationen | 10.01.2023Histologic cell shape descriptors for the retinal pigment epithelium in age-related macular degeneration
Purpose : Phenotypic alterations of retinal pigment epithelium (RPE) cells are central in age-related macular degeneration (AMD). Shape descriptors for individual RPE cells based on RPEs cytoskeleton may...
Publikationen | 10.01.2023Spectral Analysis of Human Retinal Pigment Epithelium Cells in Healthy and AMD Affected Eyes
Purpose : Individual retinal pigment epithelium (RPE) cells host hundreds of granules with AF properties (PMID: 32433758). Here, we characterized RPE cells in healthy and age-related macular degeneration...
