Two-dimensional Raman correlation spectroscopy reveals molecular structural changes during temperature-induced self-healing in polymers based on the Diels–Alder reaction
The thermally healable polymer P(LMA-co-FMA-co-MIMA) has been studied by temperature-dependent FT-Raman spectroscopy, two-dimensional Raman correlation analysis and density functional theory (DFT) calculations....
PublikationenHigh-power passively mode-locked dissipative soliton fiber laser featuring cladding-pumped non-CVD thulium-doped fiber
Owing to considerable recent progress in different fields of science and technology, high-power ultrafast laser sources that emit at a wavelength of around 2 μm have been attracting increased attention....
PublikationenBreakdown of the escape dynamics in Josephson junctions
We have identified anomalous behavior of the escape rate out of the zero-voltage state in Josephson junctions with a high critical current density Jc. For this study we have employed YBa2Cu3O7-x grain...
PublikationenSegmented cladding fiber fabricated in silica-based glass
We report fabrication of a segmented cladding fiber (SCF) in silica-based glass. An SCF with a uniform core of pure silica and cladding of periodically arranged pure silica and fluorine-doped silica in...
PublikationenDetermination of effective axial temperature profile in tube furnaces via the Viscous Stretching Method
We present an efficient approach to determine the axial temperature profile in tube furnaces by analyzing the diameter profile after stretching from a silica glass rod. Given the temporal load for stretching,...
PublikationenTransient absorption microscopy: Advances in chemical imaging of photoinduced dynamics
This article reviews the state of the art of ultrafast transient absorption microscopy, discusses current experimental concepts and highlights future challenges. The advantages of transient absorption...
PublikationenIntermolecular exciton-exciton annihilation in phospholipid vesicles doped with [Ru(bpy)2dppz]2+
The ultrafast photophysics of [Ru(bpy)2dppz]2+(dppz = dipyrido[3,2-a:2_,3_-c]-phenazine) embedded into the walls of phospholipid vesicles has been studied by femtosecond time-resolved pump–probe spectroscopy....
PublikationenA Planar Thin-Film Peltier Cooler for the Thermal Management of a Dew-Point Sensor System
The development of new application fields of MEMS devices often implies a higher degree of complexity and the integration of several functionalities within these devices. In this context thermoelectric...
