Numerische Simulationen zur Einfach- und Doppelionisation von H2 in kurzen intensiven Laserpulsen
… compared by their dependence on the molecular alignment with respect to the polarization axis. Two additional mechanisms, which are also related to rescattering, could be identified as well.

Electro-mechanically interfacing with biology using piezoelectric polymer nanostructures
… highly crystalline (up to 45 %) with a degree of molecular alignment, and that the nanowires displayed shear piezoelectricity with an estimated piezoelectric coefficient $d_{14} = 8$ pC/N. This was the first observation and quantification of shear piezoelectricity in PLLA at the nanoscale. FEA was …

Polarization characterization of nonlinear laser propagation
… due to the delayed rotational response (molecular alignment) is present which has been shown to have an effect on propagation and properties of the filament. Instabilities of the polarization of the filament lead to observation of an anomalous spectral broadening phenomenon due to …

Dipyrrin complexes and their uses as self assembling materials
… relationship between fluorescence and degree of molecular ordering (e.g. nematic phase fluorescence compared to isotropic liquid fluorescence) and several of the compounds were dissolved in a commercial nematic liquid crystal and incorporated into a twisted nematic cell in order to observe the …

Electric field-assisted immobilization and alignment of biomolecules
… and applied to achieve immobilization and alignment of biomolecules on metal electrodes in a simple one-step experiment. Neither modifications of the biomolecule nor of the electrodes were needed. The two major electrokinetic effects that lead to molecule motion in the chosen electrode …

Shear controlled orientation effects with injection mouldings produced by the SCORIM process
… shears which reflects an increase in molecular alignment and consequent improved mechanical properties. The intensity of the y-phase increased with the volume of material sheared. Strong evidence was also obtained of a linear relationship between the logarithm of the time lapse between …

The influence of heat transfer limitations on the properties of PET yarn produced by melt spinning
… is dictated by the degree of crystallinity and molecular alignment of the polymer macro-molecules parallel to the fibre axis. These properties are strongly influenced by online tensile stress and local temperature which are, in turn, affected by heat transfer effects between the quench air and …

Investigation of Electronic Molecular Materials with Magneto-Optical and Magnetic Properties
… of solid-state samples can be achieved via molecular alignment through the liquid crystalline phase. In Chapter 6, we investigate the Faraday rotation in thin films of chiral π-conjugated polymers. We discuss the impact of chirality, structural order, and film thickness on the magnetooptical …

Enhancing the Effectiveness and Availability of Orthoses by Additive Manufacturing
… LCP wavy fibres, given the high degree of molecular alignment achieved along the printing direction. Such that this design allows the brace to remain flexible during normal ankle inversion movements but stiffen rapidly under large strains to protect against ankle sprain injuries. Its …

The effect of nanostructuring and crystallinity on triboelectric energy harvesting devices for biomedical applications
… materials which experience the added effect of molecular alignment during nanostructuring, improving their piezoelectric properties and surface polarisation from additional dipole alignment. Different crystallinities of PLLA nanostructures and films were tested against nanostructures and films …

Electrospun nanofibers with tunable electrical conductivity
… and are usually available only in relatively low molecular weight forms, so that the elasticity of their solutions is insufficient for it to be electrospun directly into fibers. Considerable amount of recent work has been reported trying to make electrospun polymeric nanofibers with intrinsically …

Development and Characterization of Advanced Polymer Electrolyte for Energy Storage and Conversion Devices
… from the double helical conformation of PBDT molecular chains. We primarily develop an ionic liquid-based polymer gel electrolyte that possesses the following exceptional combination of properties: transport anisotropy up to 3.5×, high ionic conductivity (up to 8 mS cm⁻¹), widely tunable …
