Structural properties of mixed conductor Ba1−xGd1−yLax+yCo2O6−δ
PublicationBa1−xGd1−yLax+yCo2O6−δ (BGLC) compositions with large compositional ranges of Ba, Gd, and La have been characterised with respect to phase compositions, structure, and thermal and chemical expansion. The results show a system with large compositional flexibility, enabling tuning of functional properties and thermal and chemical expansion. We show anisotropic chemical expansion and detailed refinements of emerging phases as La is...

High Q-factor Microwave Fabry-Perot Resonator With Distributed Bragg Reflectors
PublicationZrealizowany został rezonator Fabry-Perot pracujący na częstotliwości 39 GHz i wykorzystujący dwie pary ćwierćfalowych kwarcowych reflektorów Bragga. Dla fali o długości 98.26 mm otrzymano dobroć ok. 560,000, co oznacza 4.3-krotny wzrost w porównaniu z identycznym rezonatorem bez reflektorów Bragga. Analizę problemu wykonano przy pomocy metody różnic skończonych w dziedzinie częstotliwości (FDFD) i porównano z uproszczonym rozwiązaniem...

Quantification of Radiation-Induced Single-Strand Breaks in Plasmid DNA using a TUNEL/ELISA-Based Assay
PublicationWprowadzono nową metodę służącą do oznaczania in vitro pojedynczych pęknięć nici DNA powstałych pod wpływem naświetlań. Porównano wyniki otrzymane z nowej metody z modelem teoretycznym. Porównano wyniki z szeroko używaną metodą elektroforezy żelowej. Pokazano, że poziom pojedynczych pęknięć powstających w niciach DNA pod wpływem promieniowania VUV jest wyższy niż zakładany na podstawie wyników otrzymywanych metodami standardowymi.

Synthesis and polymerisation techniques of molecularly imprinted polymers
PublicationMolecularly Imprinted Polymers (MIPs) are materials that has been processed using the molecular imprinting technique which permit to obtain well-defined three-dimensional cavities, with affinity to a template molecule, in the polymer matrix. Technology involves three strategies, i.e., covalent, non-covalent and semi-covalent approach, but the most popular is non-covalent approach. The most important components for the synthesis...

Engineering Au nanoparticle arrays on SiO2 glass by pulsed UV laser irradiation
PublicationWe study semi-regular arrays of Au nanoparticles (NP) obtained via UV laser irradiation of thin Au films on glass substrate. The NP structures are prepared from films of a thickness up to 60 nm produced by discharge sputtering or pulsed laser deposition, and annealed by nanosecond laser pulses at 266 or 308 nm, respectively, at fluencies in the range of 60-410 mJ/cm2. For the rare- and close-packed NP structures, consistent description...

VUV irradiation studies of plasmid DNA in aqueous solution
PublicationInteractions of VUV light and DNA samples in aqueous solutions are reported. The damage induced by such radiation is quantified by monitoring both loss of supercoiled DNA and formation of single and double strand breaks using agarose gel electrophoresis. Irradiations were performed using synchrotron VUV photons of 130, 150, 170 and 190 nm. VUV irradiation experiments revealed enhanced damage upon irradiation with 170 nm photons...

Enhanced photocatalytic, electrochemical and photoelectrochemical properties of TiO2 nanotubes arrays modified with Cu, AgCu and Bi nanoparticles obtained via radiolytic reduction
PublicationTiO2 nanotubes arrays (NTs), obtained via electrochemical anodization of Ti foil, were modified with monometallic (Cu, Bi) and bimetallic (AgCu) nanoparticles. Different amounts of metals’ precursors were deposited on the surface of NTs by the spin-coating technique, and the reduction of metals was performed via gamma radiolysis. Surface modification of titania was studied by EDS and XPS analysis. The results show that AgCu nanoparticles...
