Study of PQ/PMMA photopolymer. Part 2: experimental results
In Part 1 of this paper an extended 1D nonlocal photo-polymerization driven diffusion (NPDD) model was developed, giving the temporal and spatial variations of each chemical component concentration within...
PublicationsSelection of thermo-optical parameter of nanoparticles for achievement of their maximal thermal energy under optical irradiation
Investigations and use of nanoparticles (NPs) as photothermal (PT) agents in nanoenergy and nanotechnology are fast growing areas of research and applications. Efficiency of light-to- thermal energy conversion...
PublicationsStudy of PQ/PMMA photopolymer. Part 1: theoretical modeling
Phenanthrenequinone (PQ) doped poly(methyl methacrylate) (PMMA) photopolymer material has received much attention in the literature. However, further development requires that a more physical material...
PublicationsImaging cross-correlation FROG: measuring ultrashort, complex, spatiotemporal fields
We present imaging cross-correlation frequency-resolved optical gating (ImXFROG), a new method for the spatiotemporal phase retrieval of ultrashort pulses. It is demonstrated that ImXFROG can measure phase...
PublicationsMaking a big thing of a small cell – recent advances in single cell analysis
Single cell analysis is an emerging field requiring a high level interdisciplinary collaboration to provide detailed insights into the complex organisation, function and heterogeneity of life. This review...
PublicationsTrapped in Imidazole – How to Accumulate Multiple Photoelectrons on a Black Absorbing Ruthenium Complex
The design of light-driven multi-electron photocatalysts, e.g., for hydrogen generation requires (i) the development of efficient two electron redox pathways, which meet the energetic and kinetic requirements...
PublicationsResonance-Raman spectro-electrochemistry of intermediates in molecular artificial photosynthesis of bimetallic complexes
The sequential order of photoinduced charge transfer processes and accompanying structure changes were analyzed by UV-vis and resonance-Raman spectroscopy of intermediates of a Ru(II) based photocatalytic...
PublicationsOptical Sapphire Fiber Bragg Gratings as High Temperature Sensors
Fiber Bragg gratings (FBG) were inscribed in single crystalline sapphire fibers by fs-laser irradiation. Due to the used multi-mode air clad fiber a sapphire-FBG spectra showa a wide asymmetric peak with...
PublicationsDiffusion in binary TiO2- SiO2 glasss
The diffusion of titanium in TiO2-SiO2 glasses with up to 7 mol% TiO2 was investigated by annealing doped layers on the inner surface of quartz glass tubes between 1700 and 2000°C and measuring radial...
PublicationsA highly efficient Yb-doped silica laser fiber prepared by gas phase doping technology
In this paper we report on an alternative technique for the preparation of ytterbium (Yb)doped silica fibers and their characteristics compared to the conventional modified chemical vapor deposition (MCVD)...
