A Design Study of a Compact Small-Angle Neutron Scattering Instrument
Markus Bleuel, Miriam Siebenbürger, Peter Böni +1
Nanoscale structure determination belongs to one of the crucial tasks in materials science. Small-angle neutron scattering (SANS) is a highly valuable tool to investigate nanostruc…
Acetaminophen Interactions with Phospholipid Vesicles Induced Changes in Morphology and Lipid Dynamics
Judith U. De Mel, Sudipta Gupta, Sydney Harmon +5
Acetaminophen (APAP) or Paracetamol, despite its wide and common use for pain and fever symptoms, shows a variety of side effects, toxic effects, and overdose effects. The most com…
On the Determination of the Transition to Pure Reptation by Dielectric Spectroscopy
Mengchun Wu, Karin J. Bichler, Bruno Jakobi +1
Polymer melts show a characteristic molecular weight dependent relaxation time that can be related to the unentangled and entangled regime. At high molecular weights, influence of…
Structure and dynamics of DOPC vesicles: A transformation from unilamellar to multilamellar vesicles by n-alkyl-PEO polymer
Judith U. De Mel, Sudipta Gupta, Lutz Wilner +4
We investigate the influence of a non-ionic surfactant like polymer on phospholipid vesicles. Our results from cryogenic transmission electron microscopy (cryo-TEM), dynamic light…
Influence of salt on membrane rigidity of neu-tral DOPC vesicles
Judith U. De Mel, Sudipta Gupta, Rasangi M. Perera +5
Salt is a very common molecule in aqueous environments but the question of whether the interactions of monovalent ions Na^+ and Cl^- ,with the neutral heads of phospholipids are im…
Modeling of Transient Trapping of Fatty Acid Tails in Phospholipids
Sudipta Gupta, Gerald J. Schneider
We present the derivation of a new model to describe neutron spin echo spectroscopy and quasi-elastic neutron scattering data on liposomes. We compare the new model with existing a…
Impact of Local Stiffness on Entropy Driven Microscopic Dynamics of Polythiophene
Sudipta Gupta, Sourav Chatterjee, Piotr Zolnierczuk +2
We exploited the high temporal and spatial resolution of neutron spin echo spectroscopy to investigate the large-scale dynamics of semiflexible conjugated polymer chains in solutio…
SPHERES, Jülich's High-Flux Neutron Backscattering Spectrometer at FRM II
Joachim Wuttke, Alfred Budwig, Matthias Drochner +10
SPHERES (SPectrometer with High Energy RESolution) is a third-generation neutron backscattering spectrometer, located at the 20 MW German neutron source FRM II and operated by the…
