Recent Advances in Investigation and Application of Photocatalytic Processes based on Semiconductor Materials
Recently, semiconductor photocatalysis due to its versatile use in various fields has attracted increasing attention of researchers. Here below, we present a review on recent advances in research and application...
PublicationsRecycling of silicon: from industrial waste to biocompatible nanoparticles for nanomedicine
The formation of photoluminescent porous silicon (PSi) nanoparticles (NPs) is usually based on an expensive semiconductor grade wafers technology. Here, we report a low-cost method of PSi NPs synthesis...
PublicationsMicrometer to 15 nm Printing of Metallic Inks with Fountain Pen Nanolithography
The field of printed electronics is continually trying to reduce the dimensions of the electrical components. Here, a method of printing metallic lines with widths as small as 15 nm and up to a few µm...
PublicationsEfficient laser-driven proton acceleration from cylindrical and planar cryogenic hydrogen jets
We report on recent experimental results deploying a continuous cryogenic hydrogen jet as a debris-free, renewable laser-driven source of pure proton beams generated at the 150 TW ultrashort pulse laser...
PublicationsFrom Magnetic SQUID Prospection to Excavation – Investigations at Fossa Carolina, Germany
In 2013 large scale magnetic prospection was carried out in Franconia, Germany, to reveal remains of a canal construction and corresponding infrastructure built by order of Charlemagne in the Early Middle...
Publications140 µm single-polarization passive fully aperiodic-large pitch fibers operating near 2 µm
In this paper the authors demonstrate a single-polarization feature out of passive very large mode area fully-aperiodic large pitch fibers. It has been previously shown theoretically that one of the two...
PublicationsThree-dimensional holographic optical manipulation through a high-numerical-aperture soft-glass multimode fibre
Holographic optical tweezers (HOT) holds great promise for many applications in modern biophotonics, allowing the creation and measurement of minuscule forces on biomolecules, molecular motors and cells....
PublicationsNon-invasive characterization of optical fibers
Capillary optical fibers with hole diameters of several micrometers are important for novel plasmonic applications and medical diagnosis. In order to ensure the optical functionality of these fibers, the...
PublicationsIndependently tunable dual-wavelength fiber oscillator with synchronized pulsed emission based on a theta ring cavity and a fiber Bragg grating array
We present a fiber-integrated laser enabling independent tuning of two emission wavelengths with synchronized pulsed emission. The discrete tuning concept comprises a theta cavity fiber laser (TCFL), a...
PublicationsMonolithic optofluidic mode coupler for broadband thermo- and piezo-optical characterization of liquids
We present a monolithic fiber device that enables investigation of the thermo- and piezo-optical properties of liquids using straightforward broadband transmission measurements. The device is a directional...
