Teraaza- and hexaazacyclophanes have been synthesized via a one-step palladium catalyzed amination reaction. The chemical oxidation of cyclophanes leads to the formation of radical cations, the presence of which was manifested by the appearance of new bands in UV-Vis-NIR and IR spectra. Spins of radical cations can be…
A series of terarylenes based on 4,5-bisbenzothienylthiazole have been synthesized, and their photochromic properties are studied both in solution and in the crystalline state. The substitution effect of the central aromatic ring on the photochromic reactivity were also studied. The introduction and expansion of the π…
Short surfactant-like peptides bearing the molecular architecture of hydrophilic and hydrophobic moieties are attractive for a wide range of biological and technological applications. However, to realize the benefits offered by them we need to understand the basic physiochemical properties arising from their interfaci…
Phase-field simulation is performed to examine the effect of elastic inhomogeneity between the γ and γ′ phases on microstructure evolution of the γ′ phase in Ni-based superalloys. For solving the elastic equilibrium equation numerically in the elastically inhomogeneous system, an iterative approach is used. In this si…
This work is focused on a multidisciplinary study of a completely condensed octaisobutyl-silsesquioxane (IBUPOSS) as a model of the alkyl POSS family. IBUPOSS is characterized by the presence of eight isobutyl groups bonded to the corners of the siliceous framework. Differential scanning calorimetric measurements and…
The cationic sensitizer 5,10,15,20-tetrakis(N-methylpyridinium-4-yl)porphyrin (TMPyP) forms supramolecular complexes with native, per-methylated, sulfonated and dimethyl-sulfonated cyclodextrins (CDs). Binding interactions were proved by NMR, mass spectra, capillary zone electrophoresis, UV-Vis and fluorescence spectr…
The activity of synthetic pores, ion channels, transporters and carriers is usually determined with fluorescent probes in vesicles or by conductance measurements in planar lipid bilayers. Elaborating on more colorful alternatives, we here introduce 5(6)-carboxynaphthofluorescein (CNF) as an intravesicular pH probe for…
Immobilized Candida antarctica lipase B (CALB) was successfully employed as a catalyst to synthesize silicone aromatic polyesters by the transesterification of dimethyl terephthalate with alpha,omega-bis(hydroxyalkyl)-terminated poly(dimethylsiloxane) in toluene under mild reaction conditions.
Continuous nanofibers consisting of a thermosetic polymer are described. The fibers were obtained using a two-fluid coaxial electrospinning technique. The type of coaxial electrospinning developed in this research is unique, in that the core structure is fabricated from a 100% volume fraction oligomer liquid encapsula…
An ab initio derived force-field, previously (Cacelli et al., J. Phys. Chem. B, 2007, 111, 2130) tested and validated on the structural and dynamic properties of isotropic and nematic phases of the 4-alkyl-4′-cyanobiphenyl (nCB; n = 5–8) series, is employed here in molecular dynamics simulations to verify the model’s…
The corrosion behavior of AZ31 Mg alloy in the nondeaerated and deaerated dilute NaCl solutions was investigated by electrochemical measurements. The cathodic reaction of AZ31 Mg alloy depends on the hydrogen evolution and the oxygen reduction in nondeaerated media, while that is dominanted by the hydrogen evolution i…
A unique concept of making nanocomposites from carbon nanofiber paper was explored in this study. The essential element of this method was to design and manufacture carbon nanofiber paper with well‐controlled and optimized network structure of carbon nanofibers. In this study, carbon nanofiber paper was prepared under…
Two orthogonal non-covalent binding sites, namely metal-ligand complexation of Ru and bipyridine and intermolecular hydrogen bonding, facilitate the self-assembly of a new type of supramolecular dendrimers.
We have used classical molecular dynamics based on the Brenner potential to calculate the thermal conductivity of rectangular graphene nanoribbons up to 30 nm long. We have employed the Debye model to make the quantum correction of the classical molecular dynamics temperature. The calculated thermal conductivity is on…
Silk sericin is a family of water-soluble proteins extracted from the silkworm cocoon. Studies have been attempted to recycle the sericin waste from mulberry Bombyx mori sericulture to develop value-added products in the biomedical, pharmaceutical, cosmetic, and food industries. Accordingly, a wild species of the non-…

This paper reports the superior properties of a Cu interconnect cosputtered with a minor on barrierless Si. After heating at for , there is no observable interaction between and Si. The film remains stable after five cycles of heating at for a total of . The film resistivity is high in the as-deposited condition, and…
We prepared a responsive polyelectrolyte (ferrocene-terminated poly[1-ethyl 3-(2-methacryloyloxyethyl)imidazolium chloride], PEMEImCl) brush on an Au surface through a three-step procedure consisting of surface-initiated atom transfer radical polymerization, followed by treatment with NaN3 and by a reaction with ethyn…
A photoluminescent II-VI group semiconductor nanocrystal (NC)-based signaling platform composed of thioglycolic acid capped CdS NCs and acetylcholinesterase-acetylthiocholine enzyme catalytic reaction system was developed that was shown to be highly sensitive to nerve agents and toxic organophosphate pesticides with d…
The photostabilization of poly(vinyl chloride) (PVC) films by 2-thioacetic acid-5-phenyl-1,3,4-oxadiazole with Sn(II), Ba(II), Ni(II), Zn(II), Cu(II), and Ca(II) complexes was investigated. PVC films containing different concentrations of complexes ranging from 0.1% to 0.5% by weight were produced by the same casting…
