Soybean oleosomes behavior at the air-water interface.
TL;DR: This study is one of the first steps toward the comparison of natural emulsification concepts based on different physical structures: e.g., the animals' low density lipoproteins, where apolipoproteins with phospholipids are located only at the interface and plant oleosomes with its Oleosins, which are embedded in aospholipid monolayer and reach deep inside the oil phase.

Analysis of biosurfaces by neutron reflectometry: From simple to complex interfaces
Ann Junghans,Erik B. Watkins,Robert Barker,Saurabh Singh,Mary Jo Waltman,Hillary L. Smith,Luka Pocivavsek,Jaroslaw Majewski +7 more
TL;DR: Some of the recent accomplishments in utilizing neutron reflectometry to study highly complex systems, including in-situ experiments will result in a much better understanding of complex biological problems, have significant medical impact by suggesting innovative treatment, and advance the development of highly functionalized biomimetic materials.
Soy milk oleosome behaviour at the air–water interface
TL;DR: Surface pressure investigations and Brewster angle microscopy of oleosomes purified from raw soy milk were executed to reveal their diffusion to the air-water interface, rupture, adsorption and structural modification over time at different subphase conditions, necessary for a better understanding of the principal function ofOleosins and their interactions with phospholipids.

Neutron reflectometry studies of aluminum–saline water interface under hydrostatic pressure
Ann Junghans,Raja Chellappa,Peng Wang,J. Majewski,Giorgio Luciano,Romolo Marcelli,Emanuela Proietti +6 more
TL;DR: In this paper, the structural stability of thin aluminum layers in contact with 3.5% NaCl water solution was investigated at a temperature of 25°C and hydrostatic pressures from 1 to 600 ǫ using neutron reflectometry.

Neutron reflectometry characterization of PEI–PSS polyelectrolyte multilayers for cell culture
TL;DR: In this paper, the thickness of polyelectrolyte multilayer (PEM) films made by layer-by-layer (LbL) deposition of a strong polycation (polyethylene imine [PEI]) and a polyanion (polystyrene sulfonate [PSS]) have been characterized.
