Pinning and trapped field in MgB2- and MT-YBaCuO bulk superconductors manufactured under pressure
The relevant pinning centers of Abrikosov vortices in MgB2–based materials are oxygen-enriched Mg-B-O inclusions or nanolayers and inclusions of MgBx (x>4) phases. The high critical current densities,...
PublicationsLandau-Zener-Stückelberg-Majorana lasing in circuit quantum electrodynamics
We demonstrate amplification (and attenuation) of a probe signal by a driven two-level quantum system in the Landau-Zener regime. In the experiment, a superconducting qubit was strongly coupled to a microwave...
PublicationsThermally triggered optical tuning of π-conjugated graft copolymers based on reversible Diels-Alder reaction
In order to design a π-conjugated polymer film with tunable optical properties by thermally triggered activation of energy transfer after processing, two monodisperse phenylene ethynylene based oligomers...
PublicationsSpatially resolved spectroscopic differentiation of hydrophilic and hydrophobic domains on individual insulin amyloid fibrils
The formation of insoluble β-sheet-rich protein structures known as amyloid fibrils is associated with numerous neurodegenerative diseases, such as Alzheimer’s and Parkinson’s disease. A detailed...
PublicationsEngineering an achromatic Bessel beam using a phase-only spatial light modulator and an iterative Fourier transformation algorithm
Highlights •A novel way of generating a Bessel Beam Profile is proposed.•Beam generation is based on an iterative Fourier transform Algorithm (IFTA) and a spatial light modulator(SLM).•The SLM is...
PublicationsThe Effect of Size of the SiC Inclusions in the AlN–SiC Composite Structure on Its Electrophysical Properties
AlN–SiC–Y3Al5O12 composite materials with a high absorption of microwave frequency (27–65 dB/cm) produced by pressureless sintering of mixtures consisting of AlN(2H), Y2O3, and SiC (6H) in 46, 4,...
PublicationsMesoscopically Bi-continuous Ag–Au Hybrid Nanosponges with Tunable Plasmon Resonances as Bottom-Up Substrates for Surface-Enhanced Raman Spectroscopy
Ag-Au hybrid nanosponges (NSs) with controlled porosity and composition ratio were fabricated through a cyclic electroless deposition of Ag into the porous Au NSs. In the Ag-Au hybrid NSs, both Au and...
PublicationsFibre Optic Sensing System for Monitoring of Current Collectors and Catenary of Railways
Fibre optic sensors are excellent tools to use for monitoring of high voltage current collectors. Because of their small cross section and electrical neutrality, they are easily integrated into the current...
PublicationsSensing with ultra-short Fabry-Perot cavities written into optical micro-fibers
The small dimensions of optical fiber sensors are of particular interest to biological applications, given the ability to penetrate relatively inaccessible regions. However, conventional optical fibers...
PublicationsFundamental SERS Investigation of Pyridine and its Derivates as a Function of Functional Groups, their Substitution Position and their Interaction with Silver Nanoparticles
The Raman and SERS spectra of pyridine, 2-, 3-, and 4-pyridinemethanol and 2-, 3-, and 4-picolylamine were comprehensively studied using two different types of silver nanoparticles as SERS substrates,...
