MSE Colloquium: Jaroslaw Majewski, Neutron Scattering Studies of Polymer- and Bio-Interfaces

Prof. (Adjunct) U. California, Davis, LANL Staff, LANSCE-LC, Lujan Neutron Scattering Center LANL, Los Alamos, NM

Abstract

The non-perturbative nature of neutron scattering coupled with its isotopic sensitivity and penetrability makes it an ideal tool to study variety of organic interfaces at different environments. In this presentation I will discuss methods to create and characterize polymeric and the bio-interfaces. I will demonstrate that neutron scattering methods can help to characterize the structure, composition, and organization of these thin films and their response to external stimuli like pH, confinement, temperature and flow shear.

Bio

Jaroslaw (Jarek) Majewski is a Staff Member at the Lujan Center, at Los Alamos Neutron Scattering Center (LANSCE), at Los Alamos National Laboratory, Los Alamos, New Mexico, USA and the adjunct professor at UC Davis. He studied at the University of Warsaw in Poland (M. Sc.) and the Weizmann Institute of Science in Israel, where he received his Ph. D. He has been working in the field of x-ray and neutron scattering physics for more than 20 years and has published 170+ peer-reviewed publications related to x-ray or neutron scattering. He is a Fellow of the American Physical Society and the recipient of the Los Alamos Individual Distinguished Performance Award. The main focus of his research are biomimetic films and interfaces: ultra-thin interfacial organic films and biological systems that have novel technological applications. For example, Jarek Majewski is involved in research for developing new types of soft structured (bio)materials (Langmuir films, model lipid bi-layer membranes), protective coatings, biosensors, and nano-structured materials.
