Layered double hydroxide supported Prussian blue nanocomposites (denoted as LDH-PB) were successfully prepared via chemical method and characterized by Fourier transform IR, X-ray diffraction, transmission electron microscope (TEM) and cyclic voltammetry. With polyaniline, polystyrene sulfonate and LDH-PB the composit…
We introduce a model of diffusion of nanoparticles in solutions of flexible, polydisperse polymers. The model takes into account the effect of depletion layer with soft boundaries. The presence of depletion layer leads to nonlinear dependence of the mean square displacement (MSD) on time. Our model may be an alternati…
This paper describes the creation of and tests petformed on knit structures of three types (left-right stitch (I), double-layer (II), and double-layer with additional fillings (III)), which contain ferromagnetic materials and electroconductive materials and are designed for individual protection against occupational h…
Two novel unsymmetrical phenanthroline-fused phthalocyanine derivatives, namely metal free 2,3,9,10,16,17-hexakis(n-butyloxy)-22,25-diaza(1,10-phenanthrolino)[5,6-c1]phthalocyanine H2[Pc(OC4H9)6(dicqn)] (1) and its zinc complex Zn[Pc(OC4H9)6(dicqn)] (2), were designed, synthesized, and characterized by a series of spe…
INTRODUCTION: Polyamidoamine (PAMAM) dendrimers are a unique family of dendritic polymers with numerous pharmaceutical and biomedical applications. One major problem with these polymers is their cytotoxicity. The purpose of this study was to synthesize novel dendrimers with aldehyde terminal groups and compare their c…
Up-conversion nanoparticles (UCNPs) that emit high-energy photons upon excitation by low-energy near-infrared (NIR) radiation are emerging as new optical nanoprobes useful in biomedicine. Herein, the one pot facile synthesis of mesoporous silica-coated NaYF4:Yb/Er nanoparticles has been achieved successfully. The as-p…
Mesoporous silica films with large spherical mesopores are synthesized using new laboratory-made polystyrene-block-polybutadiene-block-polystyrene based triblock copolymers in which the polystyrene block is functionalized with hydrophilic sulfonic groups. When the relative weight of the copolymer to silica source is i…
The trans-[Cu(2)L(2)Cl(2)] (1), and cis-[Cu(2)L(2)Cl(2)]·H(2)O (2) isomers of a diphenoxido bridged Cu(2)O(2) core have been synthesized using a tridentate reduced Schiff base ligand 2-[(2-dimethylamino-ethylamino)-methyl]-phenol. The geometry around Cu(II) is intermediate between square pyramid and trigonal bipyramid…
The present work demonstrates a novel strategy to synthesize orthogonally bio-engineered magnetonanohybrids (MNPs) through the design of versatile, biocompatible linkers whose structure includes: (i) a robust anchor to bind with metal-oxide surfaces; (ii) tailored surface groups to act as spacers and (iii) a general m…
Previously reported experimental findings on Si-intercalated graphene on SiC(0001) seem to indicate the possibility of an intercalation process based on the migration of the intercalant through atomic defects in the graphene sheet. We employ density functional theory to show that such a process is in fact feasible and…
The molecular dynamics of the discotic liquid crystal pyrene-1,3,6,8-tetracarboxylic tetra(2-ethylhexyl)ester is studied by dielectric relaxation and specific heat spectroscopy. Dielectric spectroscopy shows 3 processes: a β-relaxation at low temperatures and an α-relaxation in the temperature range of the mesophases…
Layered double hydroxides (LDHs) have been studied to a great extent as environmental-friendly complex materials that can be used as photocatalysts or photocatalyst supports. ZnAl layered double hydroxides and their derived mixed oxides were chosen for the investigation of photocatalytic performances in correlation wi…
Abstract—We successfully synthesized hollow AuAg alloyed trian-gular nanoboxes (TNBs) with localized surface plasmon resonances (LSPR) spectra position from visible to NIR region. We then study the surface plasmon properties of AuAg alloyed TNBs and explore their application in surface enhanced Raman scattering (SERS)…
A tandem combinatorial reaction of four acyclic, colorless compounds (two α-aminoketones and two diones; one polar and one nonpolar for each) in aqueous solution (30 mM each, 60 °C, pH 7, 24 h) containing lipid vesicles and with or without quinones and solar illumination affords a distribution of up to 538 porphyrins…
The crystal growth behavior of dendrite-like Cu2O crystals during galvanostatic electrodeposition was investigated. The deposited Cu2O particles are single-phase cuprites and their morphologies change from octahedral in a static electrolyte to dendrites in a stirred electrolyte. The morphology evolution is attributed…
Six 5,5′-azotetrazolate based supramolecular complexes of {[Co(en)3]2(AT)3·3H2O} (1), {[M(en)2(trans-AT)2](trans-H2en)·2H2O} (M = Ni, 2; Cu, 3), {[Ni(en)2(trans-AT)](trans-AT)(trans-H2en)·2H2O} (4), {[Cu(en)2(trans-AT)]·2H2O} (5) and {[Cu(en)2(trans-AT)0.5](trans-AT)0.5} (6) (en = ethylenediamine) have been synthesize…
As a nucleating agent, 1, 3-2, 4-di (p-hydroxyl) benzylidene sorbitol (DHDBS) at mass percents (0.1 wt%, 0.2 wt%, 0.3 wt%, 0.4 wt% and 0.5 wt%) was added into isotactic polypropylene (IPP) matrix by solution/precipitation method and compression-molded method. The crystallization morphology, spherulite dimensions, and…
The crystal structures of an inorganic butane analogue, NH(3)BH(2)NH(2)BH(3) (DDAB), were determined using single crystal X-ray diffraction, revealing both anti and gauche conformations. The anti conformation is stabilized by intermolecular dihydrogen bonds in the crystal whereas two gauche conformations of DDAB obser…
The buckling characteristics of nonideal single‐ and double‐walled carbon nanotubes were studied in this work via molecular dynamics simulation method. An imperfectly straight nonideal single‐walled carbon nanotube (SWCNT) with a bent along the tube axis was used to form an array which is subjected to compression. The…
Novel near infrared-absorbing iron oxide-gold core-shell nanoparticles in pin shapes were synthesized. The nanopins are superparamagnetic, with 35-fold better surface enhanced Raman scattering activities than the conventional core-shell nanospheres and 50-fold greater photothermal properties than solid gold nanorods.…
