Size-dependent magnetic properties of iron oxide nanoparticles
Uniform iron oxide nanoparticles in the size range from 10 to 24 nm and polydisperse 14 nm iron oxide particles were prepared by thermal decomposition of Fe(III) carboxylates in the presence of oleic acid...
PublicationsThe effect of 3-amino benzoic acid linker and the reversal of donor-acceptor pairs on the electrochemical performance and stability of covalently bonded poly(pyrrole) nanotubes
The multiwall carbon nanotubes-polypyrrole (MWCNTs-PPy) composite is a well-known hybrid material suitable for energy storage applications such as capacitors. Since the electrochemical activity, and longterm...
PublicationsSurface Mobility and Ordered Rearrangement of Immobilized DNA Origami
The immobilization of DNA nanostructures on a surface is a key step for the integration of DNA-based material in nanotechnology for electronic or sensorial applications. Thereby the arrangement and distribution...
PublicationsStudying different illumination patterns for resolution improvement in fluorescence microscopy
Various types of non-uniform illumination can be used for resolution improvement in fluorescence microscopy. Here we study the differences between several types of incoherent illumination patterns, such...
PublicationsUltrafast transient absorption microscopy: Study of excited state dynamics in PtOEP crystals
We report a novel transient absorption microscope based on a tailor-made femtosecond fiber laser system operating at 250 kHz. The setup is applied to study PtOEP crystals embedded in a PBMA polymer matrix...
PublicationsEnhanced pump absorption efficiency in coiled and twisted double-clad thulium-doped fibers
Results of the first experimental demonstration of the recently proposed technique for improvement of the pump absorption in double-clad fibers by their simultaneous coiling and twisting are reported....
PublicationsSingle-Mode Multicore Fibers with Integrated Bragg Filters
Fiber Bragg gratings in single-mode fibers, used as narrowband filters, have reached a high maturity level, especially for applications in telecommunications and sensing. In spectroscopic applications,...
PublicationsDirect absorption measurements using laser induced deflection
High sensitivity and straightforward absolute calibration are combined using IPHT’s laser induced deflection (LID) technique for direct absorption measurements. The new “LID-sandwich-concept” allows...
PublicationsAmorphous silicon thin-film solar cells on glass fiber textiles
In this contribution, amorphous silicon thin-film solar cells on textile glass fiber fabrics for smart textiles are prepared and the photovoltaic performance is characterized. These solar cells on fabrics...
PublicationsFiber Bragg Grating Inscription in Optical Multicore Fibers
Fiber Bragg gratings as key components in telecommunication, fiber lasers, and sensing systems usually rely on the Bragg condition for single mode fibers. In special applications, such as in biophotonics...
