Recently, there has been significant interest in the synthesis and potential applications of semiconductor nanotubes (NTs). In this context, many efforts have been invested in developing new routes to control and engineer their surface chemistry. We report herein on a simple route to differentially and selectively fun…
New push-pull dyes featuring π-extended tetrathiafulvalene (exTTF) as the donor group and tricyanofuran (TCF) as the acceptor group were synthesized and characterized. Their broad absorption covers the entire visible spectral range and enters the near-infrared region. Electrochemistry and theoretical calculations prov…
The synthesis of ligand L(P)H(8), based on a 2,6-bispyrazolyl-pyridine scaffold functionalized by iminobismethylenephosphonate functions, is described and its pK values were determined by a combination of pH-spectrophotometric titrations and potentiometry. The interaction of L(P) with Tb(3+) was investigated in water…
Three novel inorganic−organic hybrid arsenomolybdates constructed from monocapped trivacant [As III As V Mo 9 O 34 ] 6− fragments with [Cu(en) 2 ] 2+ or [Cu(dap) 2 ] 2+ linkers, [Cu(en) 2 H 2 O] 2 {[Cu(en) 2 ][Cu(en) 2 As III As V Mo 9 O 34 ]} 2 ·4H 2 O ( 1 ), (H 2 en) 1.5 [Cu(en)(Hen)][As III As V Mo 9 O 34 ]·2H 2 O…
We report, for the first time, quadrupole mass spectrometry of neutral and positive ionic hydrocarbon species measured at the rf-biased substrate electrode of an inductively coupled plasma for acetylene rich C 2 H 2 : Ar mixtures under various bias, frequency and pressure conditions. It has been observed that, irrespe…
We explore the effects of nanoscale morphology of supporting solid substrates on alignment, defects, and director structures exhibited by thin films of triphenylamine-based discotic liquid crystals. Fluorescence confocal polarizing microscopy and intrinsic polarized fluorescence properties of studied molecules are use…
Fluorescent hydrogels: Peptide hybrids composed of an oligo(p-phenylenevinylene)-based ω-amino acid and a β-sheet-forming sequence reversibly self-assemble into fluorescent hydrogels upon a change in pH (see graphic). This study highlights how the combination of peptides and π-conjugated oligomers could be a fruitful…

Graphene is a unique 2D system of confined electrons with an unusual electronic structure of two inverted Dirac cones touching at a single point, with high electron mobility and promising microelectronics applications. The clean system has been studied extensively, but metal adsorption studies in controlled experiment…
The authors report the growth of nanowires by heating the GaN/sapphire template. It was found that density, average length, and average diameter of the nanowires all increased as we increased the grown temperature. It was also found that β-Ga2O3nanowires with good crystal quality could be achieved only at high tempera…
Ein aktiver Beitrag: Die spezifische Kapazität kohlenstoffbasierter Superkondensatoren lässt sich durch Zugabe einer elektrochemisch aktiven Verbindung (Hydrochinon) zum Leitsalz deutlich erhöhen (siehe Bild; Molekülstrukturen: grau C, weiß H, rot O). Der starke Beitrag des redoxaktiven Elektrolyten zur Pseudokapazitä…
The heterolytic dissociation of water with the previously unknown four-coordinated syn-linear (μ-oxo)divanadium core to form the five-coordinated bis(μ-hydroxo)divanadium core was confirmed by a crystal-to-crystal transformation.
Polyhedral oligomeric silsesquioxane (POSS)-polyimide (PI) hybrid nanocomposites were prepared from ether linked cyclohexyl diamine (ELCD)-modified polyamic acid with POSS derivative of octaaminophenylsilsesquioxane (OAPS). Polyamic acid (PAA) was prepared by reacting ELCD with pryomelletic dianhydride (PMDA) in 1-met…
This work is devoted to the fundamental understanding of the interaction between acoustic vibrations and surface plasmons in metallic nano-objects. The acoustoplasmonic properties of coupled spherical gold nanoparticles and nanodisk trimers are investigated experimentally by optical transmission measurements and reson…
Conductive diamond whiskers were fabricated by maskless oxygen plasma etching on highly boron-doped diamond substrates. The effects of the etching conditions and the boron concentration in diamond on the whisker morphology and overall substrate coverage were investigated. High boron-doping levels (greater than 8.4 × 1…
The orientation of cylinder-forming poly(styrene-block-methyl methacrylate) [P(S-b-MMA)] was investigated on two sets of polymeric surface treatments: 10 para-substituted polystyrene derivatives with <10 mol % poly(4-vinylbenzyl azide) and a series of poly(styrene-random-4-vinylbenzyl azide) [P(S-r-VBzAz)] copolymers…
The classical pathway of complement is an essential component of the human innate immune system involved in the defense against pathogens as well as in the clearance of altered self-components. Activation of this pathway is triggered by C1, a multimolecular complex comprising a recognition protein C1q associated with…
Electrospinning is a widely established polymer-processing technology that allows generation of fibers (in nanometer to micrometer size) that can be collected to form nonwoven structures. By choosing suitable process parameters and appropriate solvent systems, fiber size can be controlled. Since the technology allows…
Mineralized biological materials such as shells, skeleton, and teeth experience biomineralization. Biomimetic materials exploit the biomineralization process to form functional organic-inorganic hybrid nanostructures. In this work, we mimicked the biomineralization process by the de novo design of an amyloid-like pept…
