Standardized Electric-Field-Resolved Molecular Fingerprinting
Field-resolved infrared spectroscopy (FRS) of impulsively excited molecular vibrations can surpass the sensitivity of conventional time-integrating spectroscopies, owing to a temporal separation of the...
PublikationenYb-doped tapered double-clad fibers with polarization maintenance for half-kW power amplifiers
Amplifying short pulses directly within a single fiber laser system has proven to be a challenging task, primarily due to thermally induced transverse mode instabilities and detrimental nonlinear effects....
PublikationenSpatially Controlled Phase Modulation – Selective Higher-Order Mode Excitation in 3D Nanoprinted on-Chip Hollow-Core Waveguides
Higher-order modes and hollow-core waveguides are highly relevant research directions in photonics, while most studies are solely focused on fundamental modes. This work introduces a novel approach to...
PublikationenInterfacial Electrochemistry of Catalyst-Coordinated Graphene Nanoribbons
The immobilization of molecular electrocatalysts on conductive electrodes is an appealing strategy for enhancing their overall activity relative to those of analogous molecular compounds. In this study,...
PublikationenMemristive True Random Number Generator for Security Applications
This study explores memristor-based true random number generators (TRNGs) through their evolution and optimization, stemming from the concept of memristors first introduced by Leon Chua in 1971 and realized...
PublikationenVacancy-Engineered 1D Nanorods with Spatially Segregated Dual Redox Sites for Visible-Light-Driven Cooperative CO2 Reduction
Cooperative CO2 photoreduction with tailored organic synthesis offers a potent avenue for harnessing concurrently generated electrons and holes, facilitating the creation of both solar fuels and specialized...
PublikationenOverview of Nanocosmetics with Emphasis on those Incorporating Natural Extracts
The cosmetic industry is rapidly rising worldwide. To overcome certain deficiencies of conventional cosmetics, nanomaterials have been introduced to formulations of nails, lips, hair, and skin for treating/alleviating...
PublikationenEnhanced oxidoreductase acitivity of diatom frustule supported Fe3O4 for sensitive colorimetric detection of Cr(VI)
Given Cr(VI) is a ubiquitous water pollutant posing significant public health risks, there is a need for an inexpensive and easy-to-use detection tool. Herein, a diatom frustule-supported Fe3O4 (DF-Fe3O4)...
PublikationenNanoparticle doping and molten-core methods towards highly thulium-doped silica fibers for 0.79 µm-pumped 2 µm fiber lasers – A fluorescence lifetime study
We study the fluorescence lifetime of Thulium-doped silica fibers for efficient laser operation in the 2 μm “eye-safe” wavelength range pumped by 0.79 μm radiation. A large set of optical fibers...
PublikationenStructured illumination microscopy with extreme ultraviolet pulses
The relentless pursuit of understanding matter at ever-finer scales has pushed optical microscopy to surpass the diffraction limit and realize super-resolution microscopy, which enables visualizing structures...
