Lipid membrane characterization with second harmonic scattering

Cornelis Ulrich Lütgebaucks

Membranes, composed of a variety of lipids and other biomolecules, mediate signaling processes between cells and their aqueous environment. To fulfill this function, membranes can vary their composition leaflet-specific and thus alter their surface propert ...

Characterization of the interface of binary mixed DOPC:DOPS liposomes in water: The impact of charge condensation

Sylvie Roke, Carlos Alberto Macias Romero, Cornelis Ulrich Lütgebaucks

Solutions of liposomes composed of binary mixtures of anionic dioleoylphosphatidylserine (DOPS) and zwitterionic dioleoylphosphatidylcholine (DOPC) are investigated with label-free angle-resolved (AR) second harmonic scattering (SHS) and electrophoretic mo ...

A 3D printed beam splitter for polar neutral molecules

Andreas Osterwalder, Sean Dennis Steven Gordon

We describe a beam splitter for polar neutral molecules. An electrostatic hexapole initially confines and guides a supersonic expansion of ammonia, and it then smoothly transforms into two bent quadrupole guides, thus splitting the molecular beam in two co ...

Rational Design of a Low-Cost, High-Performance Metal-Organic Framework for Hydrogen Storage and Carbon Capture

Berend Smit, Kyriakos Stylianou, Andrzej Gladysiak, Matthew David Witman

We present the in silico design of a MOF-74 analogue, hereon known as M-2(DHFUMA) [M = Mg, Fe, Co, Ni, Zn], with enhanced small-molecule adsorption properties over the original M-2(DOBDC) series. Constructed from 2,3-dihydroxyfumarate (DHFUMA), an aliphati ...

Polarisation pulling in Brillouin optical time-domain analysers

Luc Thévenaz, Marcelo Alfonso Soto Hernandez

The impact of Brillouin scattering on the polarisation of pump and probe in a Brillouin optical-time domain analyser is investigated. Experimental results indicate that the Brillouin interaction integrated along the entire sensing fibre produces a polarisa ...
