The functionalization of textile fibers with intrinsically conductive polymers has become a prominent research area throughout the world. A number of coating techniques have already been utilized and optimized to get the uniform layers of conductive polymers on the surface of different substrates. In our previous stud…
We describe the modes of a Fabry–Perot cavity made of two-dimensional photonic crystal guided-mode resonance mirrors (Si3N4/air), and compare it with an ideal Fabry–Perot cavity and a cavity made of Bragg mirrors. As the evolution of modes is analyzed, a lower tuning efficiency and a larger tuning range are obtained c…
Although peptide amphiphiles have been explored as nanomaterials for different applications, nanostructures formed by hierarchical molecular assembly of sequence-specific peptidomimetics are much less developed. Such protein-like nanomaterials could enhance the current application of peptide-based amphiphiles by enric…
Abstract Heparin was covalently bonded on chemically inert PET substrate using a surface modification technique–surface interpenetrating network with the purpose of fabricating long‐lasting biocompatible materials as vascular grafts. FTIR and XPS spectra confirmed the successful heparinization of PET (PET‐Hep). The de…
Novel sandwich-type phthalocyanines containing a rare earth metal core (Pr, Nd, Eu-Lu) and macrocycles peripherally substituted by pentadecylphenoxy groups were synthesized using a cardanol-based phthalonitrile precursor and the respective lanthanide acetate. Additionally, the metal free-base analog compound was studi…
Microcrystalline and submicrometer powders of Zn(1-x)Cu(x)WO(4) (0 ≤ x ≤ 1) have been prepared by a solid-state synthesis from stoichiometric quantities of the constituent d-block metal oxide and tungsten oxide as well as from a Pechini sol-gel synthesis starting from the d-block metal nitrate and ammonium metatungsta…
Photoinduced charge transfer in a double-linked zinc porphyrin-fullerene dyad is studied. When the dyad is excited at the absorption band of the charge-transfer complex (780 nm), an intramolecular exciplex is formed, followed by the complete charge separated (CCS) state. By analyzing the results obtained from time-res…
Abstract We report the fabrication of vertically aligned single‐walled carbon nanotube (VA‐SWCNT) electrodes for a symmetric electrochemical capacitor using a simple, low‐cost ethanol‐based SWCNT growth system. From the CNT direct growth technique, the electrode was easily prepared and consequently assembled with an e…
We present electron spin resonance (ESR) measurements in single-crystalline samples of EuIn${}_{2}$As${}_{2}$ grown using the In-flux method. This compound crystallizes in a hexagonal P6(3)/$mmc$ structure and presents antiferromagnetic (AFM) ordering below ${T}_{N}=16$ K. In the paramagnetic state, a single Eu${}^{2+…
Hexagonale Magnesium-Nanokristallplättchen (MgNCs) wurden in einem porösen Metall-organischen Gerüst (MOF, siehe Bild) erzeugt. Das MgNC@MOF-Komposit speichert Wasserstoff durch Physi- und Chemisorption; dabei setzt es die isostere Wärme der H2-Physisorption sowie die H2-Chemisorptions-/Desorptions-Temperaturen deutli…
We report that poly(L-lysine)-graft-poly(ethylene glycol) (PLL-g-PEG) copolymers that bear multiple thiol groups on the polymer backbone are exceptional ligands for gold nanoparticles (AuNPs). In general, these graft copolymer ligands stabilize AuNPs against environments that would ordinarily lead to particle aggregat…
The decarbonization process for silicone resin particles in a hydrogen gas flow and the properties of resulting Si – O – C (– H ) ceramics were investigated in terms of mass loss, specific surface areas, and photoluminescence ( PL ) spectra. In particular, PL spectra of Si–O–C(–H) ceramics decarbonized in a hydrogen g…
This study analyzed the properties of poly(3,4-ethylenedioxythiophene):poly(styrene sulfonic acid) (PEDOT:PSS) thin-films prepared by spin-coating solutions made with the polar solvents methanol, acetone, or N,N-dimethylformamide (DMF). A characteristic analysis was carried out for poly(3-hexylthiophene) (P3HT) and [6…
Addition of orthophosphate has been commonly employed to suppress lead levels in drinking water. Its detailed mechanism and time required for it to become effective, however, have not been fully elucidated. In this study, we investigated the mechanistic role of orthophosphate as a corrosion inhibitor in controlling le…
The aim of this paper is to measure the induction period for gypsum nucleation when 2-phosphonobutane-1,2,4- tricarboxylic acid (also PBTC, commercial name Bayhibit) is added to a solution as an additive. A well-assessed laser light scattering technique previously devised for the measurement of induction times has bee…
We present a straightforward method to prepare amphiphilic graft copolymers consisting of hydrophobic poly(3-hydroxyalkanoates) (PHAs) backbone and hydrophilic α-amino-ω-methoxy poly(oxyethylene-co-oxypropylene) (Jeffamine®) units. Poly(3-hydroxyoctanoate)-co-(3-hydroxyundecenoate) (PHOU) was first methanolyzed to obt…
It has been shown by electrospray ionization-ion-trap mass spectrometry that B(12)I(12)(2-) converts to an intact B(12) cluster as a result of successive stripping of single iodine radicals or ions. Herein, the structure and stability of all intermediate B(12)I(n)(-) species (n=11 to 1) determined by means of first-pr…
Abstract The discovery of unusual nanorod precipitates in bismuth ferrite doped with Nd and Ti is reported. The atomic structure and chemistry of the nanorods are determined using a combination of high angle annular dark field imaging, electron energy loss spectroscopy, and density functional calculations. It is found…
The design of stimuli-responsive polymer assemblies for the controlled release of bioactive molecules has raised considerable interest these two last decades. Herein, we report the design of mechanically responsive drug-releasing films made of polyelectrolyte multilayers. A layer-by-layer (LbL) reservoir containing bi…
Abstract Li3SbS3 was synthesized by solid‐state reaction of stoichiometric amounts of Li2S and Sb2S3 in the ratio 3:1. The product is air and moisture sensitive. The crystal structure was determined from single crystals at room temperature. Pale grey Li3SbS3 crystallizes in the orthorhombic space group Pna21 (no. 33)…
