Size-exclusion chromatography small-angle X-ray scattering of water soluble proteins on a laboratory instrument

S. Bucciarelli, S. R. Midtgaard, M. Nors Pedersen, S. Skou, L. Arleth and B. Vestergaard

Coupling of size-exclusion chromatography with biological solution small-angle X-ray scattering (SEC-SAXS) on dedicated synchrotron beamlines enables structural analysis of challenging samples such as labile proteins and low-affinity complexes...

Composition and structure of high temperature dairy fouling

Hagsten, Carin; Altskär, Annika; Gustafsson, Stefan; Lorén, Niklas; Hamberg, Lars; Innings, Fredrik; Paulsson, Marie; Nylander, Tommy

The fouling structure and composition is dependent on the product, but also on the heating process applied to it. The structure will have profound effect on the cleaning process and the down time in the production plant. Here, the structure of high temperature (137 °C) milk fouling has been investigated,…

Effect of cholesterol on the molecular structure and transitions in a clinical-grade lung surfactant extract

Andersson, Jenny Marie; Grey, Carl; Larsson, Marcus; Ferreira, Tiago Mendes; Sparr, Emma

The lipid–protein film covering the interface of the lung alveolar in mammals is vital for proper lung function and its deficiency is related to a range of diseases. Here we present a molecular-level characterization of a clinical-grade porcine lung surfactant extract using a multitechnique approach consisting of H1H1

High Stiffness Cellulose Fibers from Low Molecular Weight Microcrystalline Cellulose Solutions Using DMSO as Co-Solvent with Ionic Liquid

Zhu, Chenchen; Koutsomitopoulou, Anastasia F.; Eichhorn, Stephen J.; Duijneveldt, Jeroen S. van; Richardson, Robert M.; Nigmatullin, Rinat; Potter, Kevin D.

There is a need to develop high-performance cellulose fibers as sustainable replacements for glass fibers, and as alternative precursors for carbon filaments. Traditional fiber spinning uses toxic solvents, but in this study, by using dimethyl sulfoxide (DMSO) as a co-solvent with an ionic liquid, a novel high-performance fiber with exceptional…

Clarifying the Origin of Multiple Melting of Segmented Thermoplastic Polyurethanes by Fast Scanning Calorimetry

Balko, J.; Fernández-d’Arlas, B.; Pöselt, E.; Dabbous, R.; Müller, A. J.; Thurn-Albrecht, T.

Segmented thermoplastic polyurethanes (TPU) often show multiple endothermic signals during melting in conventional differential scanning calorimetry (DSC). Repeated reorganization during heating and separate crystal melting and phase mixing have been proposed as the origin of this phenomenon. We used fast scanning calorimetry on a series of TPUs with polyether soft…

A versatile approach to different colored photonic films generated from block copolymers and their conversion into polymer-grafted nanoplatelets

Huang, Yucheng; Zheng, Yang; Pribyl, Julia; Benicewicz, Brian C.

One-dimensional photonic crystals can be formed by the self-assembly of block copolymers. However, such materials are still difficult to make due to the synthetic challenge of making high molecular weight block copolymers and the slow self-assembly characteristics of these block copolymers to form high domain spacings (d > 150 nm).…

Seeded Growth Synthesis of Gold Nanotriangles: Size Control, SAXS Analysis, and SERS Performance

Kuttner, Christian; Mayer, Martin; Dulle, Martin; Moscoso, Ana; López-Romero, Juan Manuel; Förster, Stephan; Fery, Andreas; Pérez-Juste, Jorge; Contreras-Cáceres, Rafael

We studied the controlled growth of triangular prismatic Au nanoparticles with different beveled sides for surface-enhanced Raman spectroscopy (SERS) applications. First, in a seedless synthesis using 3-butenoic acid (3BA) and benzyldimethylammonium chloride (BDAC), gold nanotriangles (AuNTs) were synthesized in a mixture with gold nanooctahedra (AuNOCs) and separated by depletion-induced…

3D printing of CNT- and graphene-based conductive polymer nanocomposites by fused deposition modeling

Gnanasekaran, K.; Heijmans, T.; van Bennekom, S.; Woldhuis, H.; Wijnia, S.; de With, G.; Friedrich, H.

Fused deposition modeling (FDM) is limited by the availability of application specific functional materials. Here we illustrate printing of non-conventional polymer nanocomposites (CNT- and graphene-based polybutylene terephthalate (PBT)) on a commercially available desktop 3D printer leading toward printing of electrically conductive structures. The printability, electrical conductivity and…

Adjuvants Based on Synthetic Mycobacterial Cord Factor Analogues: Biophysical Properties of Neat Glycolipids and Nanoself-Assemblies with DDA

Kallerup, Rie S.; Franzyk, Henrik; Schiøth, Mikkel L.; Justesen, Sarah; Martin-Bertelsen, Birte; Rose, Fabrice; Madsen, Cecilie M.; Christensen, Dennis; Korsholm, Karen S.; Yaghmur, Anan; Foged, Camilla

Synthetic mycobacterial cord factor analogues, e.g., trehalose 6,6′-dibehenate (TDB), are highly promising adjuvants due to their strong immunopotentiating capabilities, but their biophysical properties have remained poorly characterized. Here, we report the synthesis of an array of synthetic TDB analogues varying in acyl chain length, degree of acylation, and headgroup display,…
