Titanatrane, Mononuclear, Ring opening polymerization, Polylactide, PolycaprolactoneThe chemistry of atrane coordinated by the central nitro-gen atom as well as all three arms of deprotonated triethanol-amine ligand, imino-2,2',2''-triethanolate, has been inten-sively studied over the past few decades and its examples…
Abstract The enantioselective adsorption of racemic 1‐phenyl‐1,2‐ethanediol (PED) by carboxymethyl‐β‐cyclodextrin‐intercalated Zn–Al‐ layered double hydroxides (CMCD‐LDHs) has been studied. The adsorption isotherms of enantioselective as well as nonenantioselective adsorption of PED by CMCD‐LDHs have been investigated…
Control over the thickness of a silica coating on single-walled carbon nanotubes (SWNTs) is highly desirable for applications in optics and in biomedicine. Moreover, a silica coating on SWNTs would also aid in avoiding tube−tube contact and bundle formation as well as tube oxidation, a scenario conducive to the use of…
X-ray and NMR experiments were performed with simple chitosan models based on glucosamine monosaccharides and disaccharides to understand the binding properties and structures of the complexes formed between this polysaccharide and platinum(II) metals. Subjection of the glucosamine derivatives with [PdCl2(PhCN)2] prov…
Poly(L-lactic acid) (PLLA) is widely used in tissue-engineering applications because of its degradation characteristics and mechanical properties, but it possesses an inert nature, affecting cell-matrix interactions. It is desirable to modify the surface of PLLA to create biomimetic scaffolds that will enhance tissue…
The merger of a transparent plastic foil substrate with a semiconductor CdS film for a photonic application was realized using pulsed-laser deposition. Although plastic is not considered to be a favoured substrate material for semiconductor thin-film formation, the deposited CdS film possesses good adhesion, with a po…
Moleküle in Rotation: Ein „Bottom-up“-Ansatz führte zu einem supramolekularen Rotor, der an einen mechanischen Drehschalter erinnert. Durch Selbstorganisation bildet ein funktionalisiertes Porphyrin ein poröses Netzwerk mit chiralen Hohlräumen. Gastmoleküle in diesen Hohlräumen können thermisch oder mit der Spitze ein…
Dynamic Monte Carlo simulations are performed for lattice self-avoiding tail-like polymer chains with one end attached to a non-interacting and impenetrable flat surface. The configurational entropy S TL of the tail-like chain is determined by the scanning method. The entropy S TL is smaller than that of the free chai…
The surface plasma treatment of a conducting surface (fluorine-doped tin oxide (FTO)/glass; see Scheme) is discriminating for the dewetting behaviour of [2.2]paracyclophane incorporating a polyarylethynyl linear side chain (PCP 1) inducing the self-organization of the compound in nanometer-sized rodlike structures con…
Abstract Liquid–liquid phase separation is undesirable in crystallization as it leads to slow crystal growth and uncontrollable crystal morphology. Therefore, it is necessary to identify the conditions under which liquid–liquid phase split occurs, so as to avoid crystallization process taking place at such conditions.…
The adsorption and desorption phenomena of water molecules on stainless steel and aluminum surfaces have been studied by means of tritium tracer technique (TTT) with special emphasis on potential differences in the residence times in atmosphere and vacuum. Samples with a geometrical surface area of about 2cm2 have bee…
Polypyrrole (PPy) is a conducting polymer that may be electrochemically generated with the incorporation of any anionic species, including net-negatively charged biological molecules such as proteins and polysaccharides. In this article, dermatan and chloride-loaded PPy films were prepared on gold sputter-coated cover…
Abstract Novel conducting polymer composites of linseed‐oil‐based poly(urethane amide) (LPUA) were synthesized using nanostructured poly(1‐naphthylamine) (PNA). The combination of the electrically conducting PNA with LPUA was accomplished through different weight percent loadings (0.5–2.5 wt%) of the conducting polyme…
Mesoporous thin films comprised of interconnected nanocrystalline (anatase, 20 nm) TiO2 particles were functionalized with [Ru(bpy)2(deebq)](PF6)2, where bpy is 2,2'-bipyridine and deebq is 4,4'-diethylester-2,2'-biquinoline, or iron(III) protoporphyrin IX chloride (hemin). These compounds bind to TiO2 with saturation…
The magnetocaloric effect (MCE) and metamagnetic transition of LaFe11.5Si1.5 compound are studied by the measurement of magnetization, ac susceptibility, and heat capacity. The ferromagnetic order temperature is observed to be 196?K. The field-induced metamagnetic transition that causes a paramagnetic-to-ferromagnetic…
The fluorinated phenoxide OC6F5 forms the stable Eu(II) and Eu(III) derivatives (DME)2Eu(mu-OC6F5)3Eu(mu-OC6F5)3Eu(DME)2 and (DME)2Eu(OC6F5)3, as well as the heterovalent product (DME)2Eu(mu-OC6F5)3Eu(DME)(OC6F5)2, in redox reactions of Eu with HOC6F5 or in proton-transfer reactions of HOC6F5 with Eu(SPh)2. The divale…
Alkyl chain tethered bis-squaraines bind to Ca2+ ions through the participation of the negatively charged oxygen of the central cyclobutene moiety to form folded H-type aggregates. The initially formed Ca2+ complex is preorganized to facilitate cooperative allosteric binding of Ca2+, resulting in the formation of exte…
Intramolecular cyclocarbonylation reactions with palladium-complexed dendrimers on silica gel as catalysts are very effective for the synthesis of twelve- to eighteen-membered ring macrocycles. This process can tolerate a wide variety of functional groups, including halide, ether, ketone, and ester. The heterogeneous…
Suspended single crystal diamond devices, microdisks and beam structures, have been fabricated. Low energy boron ions (180keV) were implanted to create subsurface damage while maintaining an undamaged top surface; homoepitaxial growth was subsequently carried out on the material. The damaged layer was selectively remo…
Heterobimetallic molecular precursors [Ti4(dmae)6(mu-OH)(mu-O)6Cu6(OAc)9.H2O] (1) and [Zn7(OAc)10(mu-OH)6Cu5(dmae)4Cl4] (2) for the deposition of metal oxide thin films of Cu6Ti4O12 (Cu3TiO4, TiO2) and Cu5Zn7O12 (ZnO, CuO) were prepared by the interaction of Ti(dmae)4 with Cu(OAc)2.2H2O for 1 and tetrameric (N,N-dimet…
