Building a Simplistic Automatic Extruder: Instrument Development Opportunities for the Laboratory
Stefanie Klisch, Dylan Gilbert, Emma Breaux +4
A well-rounded introduction to work in a STEM laboratory is vital to scientific education. Besides the ability to use available instrumentation for sample characterization, student…
Ion-Mediated Structural Discontinuities in Phospholipid Vesicles
Judith U. De Mel, Sudipta Gupta, Gerald J. Schneider
Despite intense research, methods for controlling soft matter's spontaneous self-assembly in-to well-defined layers remain a significant challenge. We observed ion-induced structur…
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…
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…
A New Ultrasonic Transducer Sample Cell for In Situ Scattering Experiments
Sudipta Gupta, Markus Bleuel, Gerald J. Schneider
Ultrasound irradiation is a commonly used technique for non-destructive diagnostics or targeted destruction. We report on a new versatile sonication device that fits in a variety o…
Validity of Stokes-Einstein Relation in Soft Colloids up to the Glass Transition
Sudipta Gupta, Jörg Stellbrink, Emanuela Zaccarelli +6
We investigate the dynamics of kinetically frozen block copolymer micelles of different softness across a wide range of particle concentrations, from the fluid to the onset of glas…
Excess wing in glass-forming glycerol and LiCl-glycerol mixtures detected by neutron scattering
S. Gupta, N. Arend, P. Lunkenheimer +5
The relaxational dynamics in glass-forming glycerol and glycerol mixed with LiCl is in-vestigated using different neutron scattering techniques. The performed neutron spin-echo exp…
