Abstract Conjugated polymers were grafted onto cellulose substrates in an effort to create a general method for the synthesis of conjugated polymer/cellulose hybrid materials. In this report, we describe the grafting of poly(fluorene), poly(fluorenevinylene), and a poly(fluorene‐ethynylene‐phenylene) onto modified cel…
In this study, a carbon nanotube (CNT)-based Al/CNT/Al pressure sensor was designed, fabricated and investigated. The sensor was fabricated by depositing CNTs on an adhesive elastic polymer tape and placing this in an elastic casing. The diameter of multiwalled nanotubes varied between 10 and 30 nm. The nominal thickn…
Honeycomb-patterned polymer films with tunable pore size and regularity of ordered two- or three-dimensional hexagonal arrays have met with widespread interest in recent years in different areas, for instance as separation and superhydrophobic materials. Herein, 2D honeycomb-patterned films of amphiphilic ferrocenyl-b…
Efficient intermolecular energy transfer from carbostyril 124-sensitized Tb(3+) to Eu(3+) in aqueous aggregates is reported. This energy transfer was also recapitulated on the cell surface of a human kidney cell line (HEK-293T) and imaged by fluorescence microscopy as an example for the applicability of this energy tr…
In this study, the mixed self-assembled monolayers (SAMs) containing the mixture of long-chain alkanethiol, SH(CH(2))(11)NH(2) and SH(CH(2))(10)SO(3)H, was prepared as a model surface to examine the interaction between the biological environment and artificial surface. The 10% (v/v) NH(4)OH ethanolic solution and DMSO…
Kreisverkehr: Die Kupfer(I)-vermittelte Anellierung eines doppelt 1,3-Butadiin-verbrückten Carbazoldimers mit Aminen oder Na2S liefert Isophlorine mit Carbazol- bzw. Thiophen-Carbazol-Einheiten. Das thiophenhaltige Isophlorin kann zu einem Porphyrin oxidiert werden, das deutlich aromatischen Charakter hat und verstärk…
The hybrid nanocomposite coatings were processed in solution using acid-catalyzed hydrolysis and condensation of precursors 3-Glycidoxypropyl trimethoxysilane (GPTMS) and Tetraethoxysilane (TEOS) forming self assembled nanoscale composite. Coating were applied by dipping 5083 aluminium alloy in sol-gel solutions at se…
A crystalline (Na 0.5 K 0.5 )NbO 3 (NKN) phase was formed for a film grown at 600°C, but a K 5.75 Nb 10.85 O 30 (KN) second phase was also observed in this film. Formation of the KN phase was due to the evaporation of Na 2 O. A homogeneous NKN phase was developed in the film grown at 300°C and annealed at 800°C under…
A (TiNb) 3 (SiAl)C 2 solid solution was designed and synthesized to improve the high‐temperature oxidation resistance of Ti 3 (SiAl)C 2 . After doping with Nb, the oxidation resistance of Ti 3 (SiAl)C 2 is improved. Its oxidation kinetics follows parabolic behavior up to 1300°C. The oxide scale formed on (TiNb) 3 (SiA…
In situ polarized micro-Raman Spectroscopy has been utilized to determine the liquid crystal configuration inside a periodic liquid crystalline composite structure made of polymer slices alternated to films of liquid crystal. Liquid crystal, Norland Optical Adhesive (NOA-61) monomer and its polymerized form have been…
The effects of 1,2-diaminoethane (DE), 1,6-diaminohexane (DH), 1,8-diaminooctane (DO), and hydrazine (H) on the electrochemical behavior of copper in 0.1 M H 2 SO 4 were investigated using the potentiodynamic polarization and electrochemical impedance spectroscopy methods at 298 K. A significant decrease in the corros…
A variety of activated carbons (ACs) with different burnoff degrees (0–60%) and polystyrene cross-linked with divinylbenzene (PSDVB) were studied using small-angle X-ray scattering (SAXS) and nitrogen adsorption methods. The ACs demonstrate increased deviation of the pore shape from the model of slit-shaped pores with…
Abstract MWs are explored as the driving force for an SMP based on chemically crosslinked moist PVA networks. The samples show rapid shape recovery under MW irradiation, whereas dry samples experience no shape changes when irradiated. This effect is attributed to the heat created by vibrating water molecules inside th…
The pattern center of an electron backscatter diffraction (EBSD) image indicates the relative position of the image with reference to the interaction volume of the sample. As interest grows in high-resolution EBSD techniques, accurate knowledge of this position is essential for precise interpretation of the EBSD featu…
BACKGROUND: The drug/metabolite transporter superfamily comprises a diversity of protein domain families with multiple functions including transport of nucleotide sugars. Drug/metabolite transporter domains are contained in both solute carrier families 30, 35 and 39 proteins as well as in acyl-malonyl condensing enzym…
An analytical expression of the diffuse scattering (DS) intensity due to short-range order derived in a recent paper [A. Yamamoto, Acta Crystallogr. Sect. A 66, 372 (2010)] is applied to analyze DS intensities of the S1 phase at 1120 K and the quenched basic Ni rich (b-Ni) phase in decagonal Al${}_{70}$Ni${}_{22}$Co${…
Compliance with EU regulations for environmental protection sets new performance criteria to fuel injection technology in modern combustion engines for passenger and commercial vehicles. According to EURO-5 norm regulation the quality of the air/fuel mixture combustion depends mainly on an adequate spraying of the fue…
Supramolecular nanogelators that possess triple-helices on their surfaces quickly form transparent hydrogels upon mixing with collagen solutions by hydrogen bonding. The exceptional selectivity of the gelation properties for fibrous collagens is observed, whereas other biomolecules exhibit no change. This material is…
The two-dimensional (2D) Co oxide monolayer phase with (9 × 2) structure on Pd(100) has been investigated experimentally by scanning tunneling microscopy (STM) and theoretically by density functional theory (DFT). The high-resolution STM images reveal a complex pattern which on the basis of DFT calculations is interpr…
Picture this! A photoimage written in a reactive polymer with UV light is transferred into CaCO3 crystal morphologies (see picture). The CaCO3 crystal films with microscopic regular relief structures and flat surfaces are self-organized on the nonirradiated and UV-irradiated areas of the polymer matrix, respectively.
