Collective orientational order and phase behavior of a discotic liquid crystal under nanoscale confinement

Yildirim, Arda; Sentker, Kathrin; Smales, Glen Jacob; Pauw, Brian Richard; Huber, Patrick; Schönhals, Andreas

The phase behavior and molecular ordering of hexakishexyloxy triphenylene (HAT6) DLCs under cylindrical nanoconfinement are studied utilizing differential scanning calorimetry (DSC) and dielectric spectroscopy (DS), where cylindrical nanoconfinement is established through embedding HAT6 into the nanopores of anodic aluminum oxide (AAO) membranes, and a silica membrane with pore diameters ranging…

Nucleation and Growth Kinetics of ZnO Nanoparticles Studied by in Situ Microfluidic SAXS/WAXS/UV–Vis Experiments

Herbst, Maria; Hofmann, Eddie; Förster, Stephan

The synthesis of ZnO nanoparticles proceeds through a complex sequence of precursor reactions, nucleation, and growth processes. For further advancement and control of nanoparticle synthesis, a detailed understanding of the mechanisms and kinetics is essential. With the recent advancement in X-ray scattering and spectroscopy methods, in situ experiments during nanoparticle…

Two Growth Mechanisms of Thiol-Capped Gold Nanoparticles Controlled by Ligand Chemistry

Chen, Xuelian; Wei, Meng; Jiang, Shaohua; Förster, Stephan

Thiols play an important role in the synthesis of well-defined nanoparticles (NPs) with tailored properties, but their effects on the formation kinetics of NPs are still under investigation. Here, we used in situ small-angle X-ray scattering (SAXS)/UV–vis spectroscopy and time-dependent transmission electron microscopy (TEM) to elucidate the role of thiols…

Probing the Nanostructure and Arrangement of Bacterial Magnetosomes by Small-Angle X-Ray Scattering

Rosenfeldt, Sabine; Riese, Cornelius N.; Mickoleit, Frank; Schüler, Dirk; Schenk, Anna S.

Magnetosomes are membrane-enveloped single-domain ferromagnetic nanoparticles enabling the navigation of magnetotactic bacteria along magnetic field lines. Strict control over each step of biomineralization generates particles of high crystallinity, strong magnetization, and remarkable uniformity in size and shape, which is particularly interesting for many biomedical and biotechnological…

Tandem catalysis in multicomponent solvent-free biofluids

Atkins, Dylan Luke; Berrocal, José Augusto; Mason, Alexander Francesco; Voets, Ilja Karina

Enzymes are widely employed to reduce the environmental impact of chemical industries as biocatalysts improve productivity and offer high selectively under mild reaction conditions in a diverse range of chemical transformations. The poor stability of biomacromolecules under reaction conditions is often a critical bottleneck to their application. Protein engineering or…
