Self-assembly mechanism of nanoparticles of Ni-based Prussian Blue analogues at the air/liquid interface: a synchrotron X-ray reflectivity study.

2015

Prussian Blue analogue (PBA) nanoparticles can be self-assembled at air/liquid interfaces to build novel materials with interesting magnetic features. Herein, we study the influence of the size of PBA Cs0.4 Ni[Cr(CN)6 ]0.9 and K0.25 Ni[Fe(CN)6 ]0.75 nanoparticles on the self-assembly behavior by synchrotron X-ray reflectivity. Both nanoparticles show similar Z-potential values. The phospholipid dipalmitoylphosphatidylcholine and the amino surfactant dimethyldioctadecylammonium have been used as Langmuir monolayers to anchor the PBA nanoparticles and study the interplay of forces directing the self-assembly of the nanoparticles at the surfactant/liquid interface. Whereas Cs0.4 Ni[Cr(CN)6 ]0.…

Vereinheitlichung der Bezeichnungen für Verhaltenssüchte

2021

Zusammenfassung. Fragestellung: Es existiert eine Vielzahl von Begriffen für Verhaltenssüchte, die Mängel in Operationalisierung, Bezug zum Verhalten, Kompatibilität mit internationalen Klassifikationen sowie nicht stigmatisierender Nutzung aufweisen. Daher werden einheitliche Begriffe für Verhaltenssüchte benötigt. Methode: Im Rahmen einer Leitlinie zur Diagnostik und Behandlung Internetbezogener Störungen wurden Lösungen in Form eines Expertenkonsens entwickelt. Ergebnisse: Als Grundlage wurde die Einteilung von Verhaltenssüchten in der 11. Revision der International Classification of Diseases (ICD-11) genutzt. Es wurden die Begriffe Computerspielstörung (CSS) und Glücksspielstörung (GSS)…

Assembly 2

2017

Assembly 2, the home of groups “02.01: acute critical care” and “02.02: noninvasive ventilatory support”, is a growing and active assembly within the European Respiratory Society (ERS). The number of members in Assembly 2 is steadily increasing, reaching a total of 846 in 2016. The members of Assembly 2 are young, with up to 40% of the members of Assembly 2 aged <40 years, and scientifically active, with 120 accepted abstracts at the recent ERS International Congress 2106 in London. The overarching aims of Assembly 2 are to promote respiratory intensive care within ERS through educational activities (in conjunction with HERMES (Harmonised Education in Respiratory Medicine for European Speci…

Synthesis and self-assembly of novel fluorous cationic amphiphiles with a 3,4-dihydro-2(1H)-pyridone spacer

2011

Abstract The synthesis of fluorous (highly fluorinated) 3,4-dihydro-2(1 H )-pyridone-5-carboxylate cationic amphiphiles have been described, where the dihydropyridone serves as a spacer and either a pyridinium bromide or a triphenylphosphonium bromide form the polar cationic head group. The in water self-assembled aggregates have been observed by atomic force microscopy (AFM) and dynamic light scattering (DLS).

A New Monte Carlo Method for the Titration of Molecules and Minerals

2007

The charge state of molecules and solid/liquid interfaces is of paramount importance in the understanding of the reactivity and the physico-chemical properties of many systems. In this work, we porpose a new Monte Carlo method in the grand canonical ensemble using the primitive model, which allows us to simulate the titration behavior of macromolecules or solids at constant pH. The method is applied to the charging process of colloidal silica particles dispersed in a sodium salt solution for various concentrations and calcium silicate hydrate nano-particles in a calcium hydroxide solution. An excellent agreement is found between the experimental and simulated results.

Monte Carlo simulation of block copolymers

2000

Monte Carlo simulations deal with crudely simplified but well-defined models and have the advantage that they treat the statistical thermodynamics of the considered model exactly (apart from statistical errors and problems due to finite size effects). Therefore, these simulations are well suited to test various approximate theories of block copolymer ordering, e.g. the self-consistent field theory. Recent examples of this approach include the study of block copolymer ordering at melt surfaces and confinement effects in thin films, adsorption of block copolymers at interfaces of unmixed homopolymer blends, the phase behavior of ternary mixtures of two homopolymers and their block copolymer, …

Cyclic AMP-induced Chromatin Changes Support the NFATc-mediated Recruitment of GATA-3 to the Interleukin 5 Promoter

2008

Elevated intracellular cyclic AMP levels, which suppress the proliferation of naive T cells and type 1 T helper (Th1) cells are a property of T helper 2 (Th2) cells and regulatory T cells. While cyclic AMP signals interfere with the IL-2 promoter induction, they support the induction of Th2-type genes, in particular of il-5 gene. We show here that cyclic AMP signals support the generation of three inducible DNase I hypersensitive chromatin sites over the il-5 locus, including its promoter region. In addition, cyclic AMP signals enhance histone H3 acetylation at the IL-5 promoter and the concerted binding of GATA-3 and NFATc to the promoter. This is facilitated by direct protein-protein inte…
