Covalent Functionalization of CdSe Quantum Dot Films with Molecular [FeFe] Hydrogenase Mimics for Light-Driven Hydrogen Evolution
CdSe quantum dots (QDs) combined with [FeFe] hydrogenase mimics as molecular catalytic reaction centers based on earth-abundant elements have demonstrated promising activity for photocatalytic hydrogen...
Publikationen | 18.04.2023110 μmthin endo-microscope for deep-brain in vivo observations of neuronal connectivity, activity and blood flow dynamics
Light-based in-vivo brain imaging relies on light transport over large distances of highly scattering tissues. Scattering gradually reduces imaging contrast and resolution, making it difficult to reach...
Publikationen | 18.04.2023Raman Spectroscopic Imaging of Human Bladder Resectates towards Intraoperative Cancer Assessment
Raman spectroscopy offers label-free assessment of bladder tissue for in vivo and ex vivo intraoperative applications. In a retrospective study, control and cancer specimens were prepared from ten human...
Publikationen | 17.04.2023Microfluidic Filling and Spectroscopy of Colloidal CdSe/CdS Nanoplatelets in Liquid Core Fibers
Colloidal 2D semiconductor nanoplatelets are highly efficient light emitters, which exhibit large absorption and emission cross sections, and constitute promising laser gain media. However, if dispersed...
Publikationen | 17.04.2023Gas transport mechanisms through molecular thin carbon nanomembranes
Molecular thin carbon nanomembranes (CNMs) synthesized by electron irradiation induced cross-linking of aromatic self-assembled monolayers (SAMs) are promising 2D materials for the next generation of filtration...
Publikationen | 18.04.2023Simultaneous Infrared Spectroscopy, Raman Spectroscopy, and Luminescence Sensing: A Multispectroscopic Analytical Platform
Scientific questions in fields such as catalysis, monitoring of biological processes, or environmental chemistry demand analytical technologies combining orthogonal spectroscopies. Combined spectroscopic...
Publikationen | 07.03.2023Diiodo-BODIPY sensitizing of [Mo3S13]2- cluster for noble metal-free visible light-driven hydrogen evolution within a polyampholytic matrix
We report on a photocatalytic setup that utilizes the organic photosensitizer (PS) diiodo-BODIPY and the non-precious-metal-based hydrogen evolution reaction (HER) catalyst (NH4)2[Mo3S13] together with...
Publikationen | 18.04.2023Cavity-enhanced field-resolved spectroscopy
Femtosecond enhancement cavities1 are key to applications including high-sensitivity linear2–4 and nonlinear5,6 gas spectroscopy, as well as efficient nonlinear optical frequency conversion7–10. Yet,...
Publikationen | 06.09.2022High-throughput Raman spectroscopy allows ex vivo characterization of murine small intestinal intra-epithelial lymphocytes (IEL)†
T cells are considered to be critical drivers of intestinal inflammation in mice and people. The so called intra-epithelial lymphocyte (IEL) compartment largely consist of T cells. Interestingly, the specific...
Publikationen | 03.04.2023Do lipids tune B cell signaling?
The role of lipid membrane domains in the activation of immune cells remains elusive. New microscopy data on B cell signalling support a mechanism in which lipid membrane domains consolidate upon B cell...
