Improved polarizing neutron optics with increased reflectivity, enhanced polarization, less diffuse scattering and eliminated magnetic coercivity

by Anton Zubayer Neutron optics are essential parts of neutron scattering facilities, where they guide, collimate, focus, and polarize the neutron beam tailored to each beamlines experiments. The most common neutron optics are multilayer neutron optics which are characterized by alternating layers of materials. For polarizing neutron optics, one of the layers must be magnetic […]

Student’s Spotlight – Ratchawit (Leo) Janewithayapun

Leo is a PhD student at Chalmers University working on the characterization and synthesis of melt-processable materials derived from wheat bran. Polysaccharides, such as cellulose or xylan are not melt-processable in their native state. However, with chemical modification, these abundant natural polymers can be transformed into materials exhibiting plastic-like processability and mechanical properties. In his […]

Student’s Spotlight – Karthika Kariattukarakaran Thilakan

Karthika is a PhD student from Uppsala University, working on the structure-property relationship in magnetic materials. Her primary focus involves working with metallic alloys, specifically magnetic quasicrystal approximants. Her research project consists of two main parts: the first delves into complex magnetic structures, with a focus on understanding non-trivial magnetic ground states and identifying universal […]

The Onset of Molecule-Spanning Dynamics in Heat Shock Protein Hsp90

by Felix Roosen-Runge Proteins are the biomacromolecular motors of life. While earlier accounts stressed the lock-key concept of protein function, a more complete understanding needs to take into account motions and molecular flexibility as ingredients how specific functions can be performed. In particular, larger conformational changes are known to reflect allosteric changes from active to […]

Student’s Spotlight – Juanita Francis

Juanita is a third-year PhD student from Lund University, focused on understanding the formation of silk model systems—specifically, recombinant Cylindriform silk and reconstituted silkworm silk. Her project will help in developing new design rules for mediating protein self-assembly by examining the aqueous polymer processing exhibited by cylindriform silk proteins. The transfer of this technology could […]

Interaction of a Histidine-Rich Antimicrobial Saliva Peptide with Model Cell Membranes: The Role of Histidines

by Amanda Eriksson Skog, Yuri Gerelli and Marie Skepö Here we present a continuation study of our previous paper, Spontaneous Formation of Cushioned Model Membranes Promoted by an Intrinsically Disordered Protein, in which we found that upon the interaction of Histatin 5 (Hst5) with a model lipid bilayer, a peptide cushion spontaneously forms underneath the […]
