Dotierungsphänomene: Die Dotierung mit Natriumionen führt zur Bildung monodisperser extrem dünner La2O2S-Nanoplättchen mit einstellbaren selbstorganisierten Überstrukturen (siehe Bild) und robuster Fluoreszenz in Tensidlösungen. Durch die Dotierung entstehen Sauerstoff-Fehlstellen im Wirtgitter während der Sulfurierun…
A miniaturized electron probe X-ray microanalyzer (EPMA) with a small chamber including the electron source and the sample stage was realized using a pyroelectric crystal as an electron source. The EPMA we propose is the smallest reported so far. Performance of the EPMA was evaluated by investigating energy of obtaine…
This work addresses the conception of purely organic magnetic materials by properly bridging high-spin polycyclic hydrocarbons A and B, through covalent ligands L. The strategy varies two degrees of freedom that govern the magnetic character of the A-L--B sequence, namely, the bridge response to spin polarization and…
We have synthesized polycrystalline samples of Eu(1-x)K(x)Fe2As2 (x = 0-1) and carried out systematic characterization using x-ray diffraction, ac and dc magnetic susceptibility, and electrical resistivity measurements. A clear signature of the coexistence of a superconducting transition (T(c) = 5.5 K) with spin densi…
Abstract The physical properties of microcapsules are largely influenced by the synthesis conditions such as weight ratio of core/shell material, agitation rate, reaction time, and different emulsifier. Different synthesis condition would lead to different property. It is an important issue for application in composit…
The commonly used sessile drop method for measuring contact angles and surface tension suffers from errors on superhydrophobic surfaces. This occurs from unavoidable experimental error in determining the vertical location of the liquid-solid-vapor interface due to a camera's finite pixel resolution, thereby necessitat…
Abstract Smart organic–inorganic hybrids are prepared using non‐covalent interactions between water‐soluble silsesquioxane nanoparticles and two amino acid‐based block copolymers prepared by reversible addition–fragmentation chain transfer (RAFT) polymerization. A block copolymer displaying lower critical solution tem…
The ditopic ligand PyPzOAPz (N-[(Z)-amino(pyrazin-2-yl)methylidene]-5-methyl-1-(pyridin-2-yl)-1H-pyrazole-3-carbohydrazonic acid) was synthesized by in situ condensation of methyl imino pyrazine-2-carboxylate with 5-methyl-1-(2-pyridyl) pyrazole-3-carbohydrazide. In this work we have also used two of our earlier ligan…
Elucidation of membrane protein structures have been greatly hampered by difficulties in producing adequately large quantities of the functional protein and stabilizing them. A6D and A6K are promising solutions to the problem and have recently been used for the rapid production of membrane-bound G protein-coupled rece…
Abstract This study aims to provide insights into the ability of amphiphilic cations to influence the assembly of hybrid organic‐inorganic crystal lattices using hydrophobic interactions. To investigate the hypothesis, a prototype amphiphilic cation, tert ‐butyldiethanolammonium, was employed together with molybdenum…
Symmetrical triphenylene dimers connected by a bis-triazole moiety have been synthesized and characterized. The bis-triazole part is formed as final step utilizing a straightforward double click reaction (CuAAC) allowing further structural variations of the linker. The 1,3-bis(triazol-1-yl)propyltriphenylene-based dim…
Abstract Polyoxymethylene (POM) has been widely utilized in industry due to its light weight properties in engineering plastics. At present, POM applications are expanding into the car industry, especially in fuel tanks. Hindered alkyl phenol derivatives have been used as antioxidants for POM; however, these compounds…
The confined self-assembly of asymmetric diblock copolymer polystyrene- block -poly(methyl methacrylate) (PS- b -PMMA) within an array of silica nanobowls prepared using a colloidal spheres templating technique is investigated. By manipulation of the nanobowl size, block copolymer (BCP) thickness, and interfacial inte…
Dense AlN–SiC solid solution ceramics with 25–75 mol% AlN were fabricated by spark plasma sintering using hexagonal SiC and AlN powders without additives. The bending strength reaches 800 MPa at room temperature with a fracture toughness of about 5 MPa·m 1/2 . The high bending strength can be retained at high temperat…
Anisotropic etching of silicon in KOH solutions saturated with tertiary-butyl alcohol (tert-butanol) was studied in this paper. The influence of KOH concentration of the solution with tert-butanol on Si(1 0 0) surface roughness and convex corners undercut were examined. It was shown that the largest reduction of conve…
A new, versatile substrate design for surface-enhanced Raman spectroscopy (SERS) is introduced that provides better illumination and collection efficiency than other solid substrates. It uses sheets of 5 nm diameter gold nanoparticles that are draped by drying-mediated self-assembly onto 100 nm thick silicon nitride m…
Abstract Poly(methyl methacrylate) (PMMA)/layered double hydroxides (LDH) nanocomposites were synthesized by in situ bulk polymerization. The LDHs were synthesized by coprecipitation method. Eight LDHs having different compositions were produced, varying the divalent/trivalent cations (Zn/Al, Mg/Fe), the ratio between…
Abstract Nano‐CaCO 3 was used as nano‐scale filler and poly(1,2‐propylene glycol adipate) (PPA) was used as polymeric plasticizer in flexible poly(vinyl chloride) (PVC) sheets for the partial replacement of di(2‐ethyl hexyl) phthalate (DOP) in this paper. The effect of PPA and nano‐CaCO 3 on restraining DOP migration…
Functionalization of single wall carbon nanotubes (SWCNTs) is desirable to enhance their ability to be incorporated into polymers and enhance their bonding with the matrix. One approach to carbon nanotube functionalization is by oxidation via a strong oxidizing agent or refluxing in strong acids. However, this approac…
Nanocomposite materials were prepared via glycerol plasticized soy protein as the matrix and in situ fabricated silica as thereinforcing phase. The silica nanoparticles were synthesized in the protein environment by sodium silicate as a precursor. The resulting composites were characterized by Fourier transform infrar…
