A series of Pb(Yb1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 ternary ferroelectric crystals with different compositions have been grown by the top-seeded solution growth technique in order to investigate systemically this ternary system based on the single crystal form. The compositional segregation and the compositional depe…
Six inorganic-organic hybrid compounds, namely, [Cu(2)(2,4'-tmbpt)(2)(β-Mo(8)O(26))(H(2)O)(2)]·7H(2)O (1), [Cu(2,4'-tmbpt)(γ-Mo(8)O(26))(0.5)(H(2)O)]·H(2)O (2), [Co(2,4'-Htmbpt)(2)(γ-Mo(8)O(26))(H(2)O)(2)] (3), [Zn(2,4'-Htmbpt)(2)(γ-Mo(8)O(26))(H(2)O)(2)] (4), [Ni(2,4'-tmbpt)(α-Mo(8)O(26))(0.5)(H(2)O)]·2.5H(2)O (5) an…
The continuum model and molecular dynamic (MD) simulation are effective in the modeling of mechanic behaviors of nano-materials. This paper presents a brief review of vibrations of single-walled carbon nanotubes (SWCNTs) investigated using the nonlocal beam model and nonlocal rod model and MD simulation. The nonlocal…
The tetragonal Cd0.25Nd0.50□0.25WO4 compound (□ – statistically distributed vacancies in cation sublattice) and its gadolinium diluted Cd0.25Gd0.50□0.25WO4:Nd3+ analogue as well as the monoclinic CdNd2W2O10 phase and its yttrium diluted CdY2W2O10:Nd3+ analogue were synthesized by the high temperature solid-state react…
We study the kinetics and mechanism of intercalation and de-intercalation of small anions during the formation of crystalline α-Co(OH)2 and its transformation to β-Co(OH)2 within a reaction–diffusion framework. We therein use fluorescence spectroscopy with Rhodamine 6G (Rh6G) as a probe as well as other spectroscopic…
The demand for nonlinear optical (NLO) materials with exceptional NLO properties is very large, and hence the search for such materials should be continued not only to enhance their functions in current applications but also to help expedite the materialization of photonics in which photons instead of electrons are us…
Imidazolium ionic liquids (ILs) have the capacity to exert multiple functions as additives for the formation of epoxy-silica nanocomposites, via the simultaneous sol–gel process and epoxy network build-up. This study addresses the effect of ILs on the reinforcement of tensile properties in rubbery epoxy-silica nanocom…
Glioblastoma with high mortality has been one of the most serious cancers threatening human health. Because of the present treatment limitations, there is an urgent need to construct a multifunctional vesicle for enhancing the treatment of in situ malignant glioblastoma. In our study, drug and gene co-loaded magnetic…
A series of spin crossover iron(III) complexes with the general composition [Fe(4OH-L6)]X (H2-4OH-L6 = 1,8-bis(4-hydroxysalicylaldiminato)-3,6-diazaoctane; X = Cl, 1a; Br, 1b; I, 1c) was prepared. A combination of the results following the single crystal X-ray analysis, infrared and EPR spectroscopy, and temperature d…
Seven lanthanide-cobalt heterometallic three-dimensional coordination polymers: {[Ln(3)Co(2)(BPDC)(5)(HBPDC)(H(2)O)(5)](ClO(4))(2)·mH(2)O}(n) (Ln = Eu (1, m = 10.25), Gd (2, m = 8), Tb (3, m = 9.5), Dy (4, m = 11), Ho (5, m = 10.5), Tm (6, m = 11), Lu (7, m = 10.25); BPDC = 5,5'-dicarboxylate-2,2'-dipyridine anion) we…
Potassium additives slightly decreased catalytic activity for NH3-SCR of NO when the mass amount of K2O was less than 1.0%, but dramatically decreased the catalytic activity when the mass amount of K2O was more than 3.0%. The deactivation mechanism was that potassium additives directly decreased the specific surface a…
In recent years considerable attention has been given to methods for modifying and controlling the electronic and quantum mechanical properties of graphene quantum dots. However, as these types of properties are indirect consequences of the wavefunction of the material, a more efficient way of determining properties m…
A number of nonsymmetric, optically active, liquid crystal dimers belonging to three different series have been synthesized by condensing cholesteryl ω-(4-hydroxyphenoxy)alkanoates with cinnamic acids bearing mono-, di- and tri-alkoxy tail/s; these are in turn prepared by Knoevenagel condensation of corresponding benz…
Abstract Summary: The use of renewable raw materials in the polymer industries is becoming increasingly popular because of environmental concerns and the need to substitute fossil resources. Plant oils with triglyceride backbones can be chemically modified and used to synthesize polymers from renewable resources (biop…
Redox-responsive metallo-supramolecular polymers (MSPs), consisting of a ditopic ligand end-capped poly(tetrahydrofuran) (pTHF) macromonomer self-assembled with copper ions, have been developed where the degree of polymerization of the MSP, and therefore the viscosity of its solutions, depends on the oxidation state o…
Dendritic-linear block copolymers that have pH responsive poly(benzyl ether) dendrons and temperature responsive PiPrOx chains have been designed by copper-mediated click reactions. These copolymers exhibit sharp thermal transitions with a wide range of pH-dependent thermal transition temperatures.
By employing a thermal oxidation strategy, we have grown large area porous Cu2O from Cu foil. CuO nanorods are grown by heating Cu which were in turn heated in an argon atmosphere to obtain a porous Cu2O layer. The porous Cu2O layer is superhydrophobic and exhibits red luminescence. In contrast, Cu2O obtained by direc…
The local laser heat treatment of precipitation hardenable aluminum alloys enables the tailoring of the materials properties and the manufacturing of lightweight and crash-proof components for the body in white. For conventional aluminum sheet metals and profiles the formability is enhanced by an indirect approach. Th…
Supramolecular copolymerization from a mixture of comonomers with different hydrophilicities may offer an easy and convenient access to form thermoresponsive supramolecular copolymers with varied phase transition temperatures by simply varying ratios of the comonomers. Herein, supramolecular dendronized copolymers (SD…
The possibility of generating MgH(2) nanoparticles from Grignard reagents was investigated. To this aim, five Grignard compounds, i.e. di-n-butylmagnesium, tert-butylmagnesium chloride, allylmagnesium bromide, m-tolylmagnesium chloride, and methylmagnesium bromide were selected for the potential inductive effect of th…
