40 μm core diameter ytterbium-doped VLMA fiber for high-peak-power nanosecond pulse amplification
In the context of microelectronic processing applications, the development of nanosecond infrared pulsed laser sources with high peak and average power is essential to support the ongoing effort to improve...
PublikationenFewer photons, more hydrogen: effects of dynamic irradiation on light-driven hydrogen evolution by thiomolybdate catalysts
Molecular molybdenum sulfide clusters such as [Mo3S13]2− ({Mo3}) are promising earth-abundant catalysts for the light-driven hydrogen evolution reaction (HER). Their catalytic performance strongly depends...
PublikationenMultiexciton absorption cross sections of CdSe@CdS nanorods studied using pump–repump–probe spectroscopy
While the multiexciton dynamics in semiconductor nanocrystals is widely explored, to determine the absorption cross sections for multiexcitons of varying order is still a challenge. In this study, we performed...
PublikationenUV emission quenching in silicon-coupled upconverting nanocomposites
This study reports significant quenching of ultraviolet (UV) emission from NaYF4:Yb3+,Tm3+ upconversion nanoparticles (UCNPs) by silicon nanoparticles (SiNPs). SiNP-UCNP nanocomposite was fabricated using...
PublikationenAdvanced characterization of block copolymer nanostructures: integrating tip-enhanced Raman scattering and atomic force microscopy for nanoscale chemical, structural, and mechanical insights
Biocompatible and degradable block copolymers offer a versatile alternative to lipids for designing advanced drug delivery systems. However, their self-assembly into hierarchical nanostructures and their...
PublikationenEffect of Organic Binders on the Film Morphology of Hydrogen-Terminated Nanodiamonds Used for Electron Extraction in Organic Solar Cells
Like other carbon nanoparticles, diamond nanoparticles, also known as nanodiamonds (NDs), tend to aggregate when they are dispersed in solution or when they are cast on a substrate. This is mainly due...
PublikationenEfficient delivery of magnolol via polymer and hybrid lipid-polymer particles to human macrophages
Inflammation is a complex host response to combat infections and eliminate pathogens. While essential for tissue repair and homeostasis, prolonged inflammation can lead to chronic disorders. Specialized...
PublikationenPhage–antibiotic synergy restores β-lactam efficacy in MDR Klebsiella quasipneumoniae biofilms and suppresses resistance
Background: Biofilms formed by multidrug-resistant (MDR) Klebsiella spp. present a significant clinical challenge due to elevated antibiotic tolerance. Bacteriophages (phages) represent a promising alternative,...
PublikationenSiamese networks in Raman spectroscopy: Towards a better performance against replicate variability
The power of Raman spectroscopy is largely enhanced by machine learning and chemometrics, which extract and translate the spectral features into high-level biological or clinical knowledge by constructing...
PublikationenIdentification of Natural and Artificial Modifications in DNA at the Nanometer Level
The modification of nucleobases in nucleic acids is a naturally occurring process that can affect various positions of the heteroaromatic ring systems. In addition, by the targeted introduction of an artificial...
