Synthetic solvent systems for the fine-tuned preparation of CdS nanocrystallites, active in visible-light photocatalytic hydrogen production, were studied. To control crystallite size and spectral properties, the CdS crystals were synthesised by using different solvent systems, containing a series of tetrabutylammoniu…
Fang mich doch! Multifunktionelle polymerbasierte Nanopartikel wurden synthetisiert, die Zielproteine reversibel und temperaturgesteuert einfangen und wieder freisetzen, ohne sie zu denaturieren. Eine optimierte Kombination funktioneller Monomere führt zur selektiven Bindung des Zielproteins in Gegenwart anderer Prote…
The synthesis and characterization of cadmium(II) and calcium(II) complexes with N , O -bidentate ligands derived from pyrazinecarboxylic acid (3-hydroxy-2-quinoxalinecarboxylic acid HL 1 , pyrazine-2-carboxylic acid HL 2 ) are reported. Obtained compounds [Cd(L 1 ) 2 (H 2 O) 2 ](H 2 O) 2 ( 1 ), [Cd(L 2 ) 2 ] n ( 2 )…
This work reports for the first time a simple and effective approach to trigger a spheres-to- vesicles morphological transition from amphiphilic block copolymer/polyelectrolyte complexes in aqueous solution. Vesicles and large compound vesicles (LCVs) were prepared via complexation of polystyrene-block-poly(ethylene o…
New measurements of ion energies and currents in type I and mitigated ELMs have been carried out in the ASDEX Upgrade far scrape-off layer using a retarding field analyser (RFA). The ion temperature averaged over an ELM, T i ELM measured 35–60 mm outside the separatrix (i.e. 15–25 mm in front of the outboard limiter)…
The gradient on block copolymer concentration through film thickness as well as the effects of casting solvents used on the nanostructuring of a thermosetting epoxy coating modified with an epoxidized poly(styrene- b -butadiene- b -styrene) (SBS) triblock copolymer was studied by means of atomic force microscopy and a…
Hydrothermal reactions of Mn(II), Co(II), Cu(II), and Cd(II) salts with 2-((1 H -1,2,4-triazol-1-yl)methyl)-1 H -imidazole-4,5-dicarboxylic acid (H 3 tmidc) lead to four novel coordination polymers, namely, [Mn 3 (tmidc) 2 (H 2 O) 4 ]·(H 2 O) 6 ( 1 ), [Co 3 (tmidc) 2 (H 2 O) 4 ]·(H 2 O) 4 ( 2 ), [Cu 3 (tmidc) 2 (H 2 O…
We report herein the synthesis and physicochemical characterization of seven new indium–pyrazine-2,5-dicarboxylato (pzdc) and pyridazine-3,6-dicarboxylato (pddc) compounds: (dma) 6 [In 6 (μ-pzdc) 12 ]· x H 2 O ( 1 ), (dea) 6 [In 6 (μ-pzdc) 12 ]· x H 2 O ( 2 ), {(tma)[In(μ-pzdc) 2 ]·2H 2 O} n ( 3 ), {(dea)[In(μ-pzdc) 2…
In this work, IrO(2)-based powders are screened by cyclic voltammetry for the determination of the electrochemical active sites and for the qualitative evaluation of the iridium atoms speciation. All results are obtained using a cavity-microelectrode as powder holder, thus exploiting the features of this innovative to…
Collagen is the major component of skin, tendons, ligaments, teeth, and bones, it provides the framework that holds most multicellular animals together, and collagen type I constitutes the major fibrillar collagen of bone. Because of the complexity of collagen's structure, the study of post-translational modifications…
Two noninterpenetrated MOFs with strikingly different structures, NU-108-Cu and NU-108-Zn, were prepared from a single hexa-carboxylated ligand. NU-108-Cu contains paddlewheel-coordinated copper ions as nodes and is based on a 3,24 network associated with an inherently noncatenating rht -topology. Modifications introd…
Feed for farmed aquatic organisms should guarantee reasonable degree of stability in aquatic medium, long enough for organisms to consume it. Indeed, there is a general complaint about the loss of nutritional and attractive properties upon exposure of a diet to water. Natural substances able to generate firm pellet fe…
This review summarizes the work conducted in the last decade on the fabrication of mesostructured patterns, which have lateral dimensions within the nano- and microscales, over a wafer-scaled size by means of dynamic self-assembly using Langmuir-Blodgett (LB) transfer or dip-coating. First, strategies to form mesostru…
FTU plasma discharges with an extremely high amount of Li injection have been performed using a poloidal liquid lithium limiter acting as the principal Li source in the shadow of the main TZN toroidal limiter. Very peculiar of these discharges is the formation of a ‘virtual’ toroidal lithium limiter that redistributes…
Cruciform oligo(phenylene ethynylene)s (OPEs) with an extended tetrathiafulvalene (TTF) donor moiety (OPE5-TTF and OPE3-TTF) and their simple analogues (OPE5-S and OPE3) without conjugated substituents were used to form high-quality self-assembled monolayers (SAMs) on ultraflat gold substrates. Molecular junctions bas…
Reconstruction of critical sized bone injuries is a major problem that continues to inspire the design of new materials and grafts. Natural ceramics (hydroxyapatite (HA) coralline HA, or synthetic HA) and β-tricalcium phosphate (β-TCP) are being explored for use as scaffolds in bone tissue engineering, among several o…
Trifluoromethyltrimethylsilane, (CH 3 ) 3 SiCF 3, in the presence of CsF serves as an excellent CF 3 group-transfer reagent, and reaction with Cp 2 TiF 2 in THF gives the titanocene trifluoromethyl fluoride complex Cp 2 Ti(CF 3 )(F) ( 1; Cp = C 5 H 5 ) in 60% isolated yield. Reaction of complex 1 with the trimethylsil…
A series of new phospholium acenes, quaternized with benzyl groups, was synthesized. Both different π-conjugated backbones and electron-donating/-withdrawing benzyl groups were systematically studied to reveal details on the nature of their structural dynamics. Extensive NMR studies (including variable concentration/t…
We simulate liquid water between hydrophobic walls, separated by 0.5 nm, to study how the diffusion constant D(∥) parallel to the walls depends on the microscopic structure of water. At low temperature T, water diffusion can be associated with the number of defects in the hydrogen bond network. However, the number of…
Atomistic molecular simulation methods are now able to explore complex protein or protein-ligand dynamical space in a tractable way with methods such as meta-dynamics or adaptive biasing force. However, many of these methods either require a careful selection of reaction coordinates or the knowledge of an initial path…
