Indium and nitrogen codoping in ZnO leads to a solid solution of InN in ZnO with a composition of (Zn 1− z In z )(O 1− x N x ). A simple solution combustion method has been adopted to prepare the above materials in less than 10 min with metal nitrates as the metal ion source and urea as fuel. With reference to ZnO, si…
Molecular dynamics simulations of poly(ethylene terephthalate) (PET) oligomers are performed in the isobaric-isothermal (NpT) ensemble at a state point typical of a finishing reactor. The oligomer size ranges from 1 to 10 repeat units. We report thermodynamic properties (density, potential energy, enthalpy, heat capac…
Abstract Polyol/nanosilica organic–inorganic hybrids (Si/Lpol) were prepared through facile sol–gel chemistry. Tetraethoxyorthosilane (TEOS) and linseed polyol (Lpol) obtained by hydroxylation of linseed oil were used as inorganic and organic precursors, respectively. Si/Lpol was further treated with toluene‐2,4‐diiso…
The polarized Raman spectra of ${\text{MnWO}}_{4}$ single crystals were studied between 5 and 300 K. All $8{A}_{g}+10{B}_{g}$ Raman active modes were identified and assigned to definite atomic motions in close comparison with the frequencies and eigenvectors predicted by shell model calculations. No detectable phonon…
In this study, we report a facile and rapid synthesis strategy for preparing ultralong ZnO nanowire (NW) arrays by anodizing zinc foil at room temperature in a slightly basic solution, followed by annealing treatment. Detailed structure and composition characterizations are presented, including scanning electron micro…
We present a series of small-molecular trisazobenzene chromophores, including, for instance, 1,3,5-tris{[4-[4-[(4-cyanophenyl)azo]phenoxy]butyryl]amino}benzene that feature a remarkably stable light-induced orientation in initially amorphous thin-film architectures. It is demonstrated that for optimal performance it i…
ZnO nanorods with excellent optical and electro-optical emission characteristics were grown using high- and low-temperature techniques on solid and soft substrate materials. The solid crystalline substrates included p-4H-SiC and p-GaN, while the soft amorphous substrates included p-type polymers deposited on glass and…
In this work, we studied the surface charge of alpha-alumina treated with carboxylic acids with different carbon chain length. The results show the possibility of controlling surface charges of alumina by using different concentrations of carboxylic acids or changing the size of the carbon chain of the acids. We also…
The gelation of ionic liquids is attracting significant attention because of its large spectrum of applications across different disciplines. These 'green solvents' have been the solution to a number of common problems due to their eco-friendly features. To expand their applications, the gelation of ionic liquids has…
The preparation, characterization, and optimization of the functional properties of mono- and polynuclear coordination complexes containing heteroaromatic nitrogen ligands are discussed here, taking the advantage of numerous studies performed in our laboratories on exploring a variety of different metal ions and polyt…
Chemical synthesis, stability, and characterization of a new albumin-based magnetic nanocarrier containing cobalt ferrite nanoparticles is reported. The BSA–cobalt-based nanocarrier is tested as a theranostic nanomedicine: both diagnostic abilities in vivo and therapeutic hyperthermic effects on standard human tumor c…
We report that the $(\mathrm{Ba},\mathrm{K}){\mathrm{Fe}}_{2}{\mathrm{As}}_{2}$ superconductor (transition temperature, ${T}_{c}\ensuremath{\sim}38\text{ }\text{ }\mathrm{K}$) has an inverse iron isotope coefficient ${\ensuremath{\alpha}}_{\mathrm{Fe}}=\ensuremath{-}0.18(3)$ (where ${T}_{c}\ensuremath{\sim}{M}^{\ensur…
In this third paper of the series, which started with Bailey et al. [J. Chem. Phys. 129, 184507 (2008); ibid. 129, 184508 (2008)], we continue the development of the theoretical understanding of strongly correlating liquids--those whose instantaneous potential energy and virial are more than 90% correlated in their th…
Abstract A series of porphyrins with three maltohexaose units and one alkyl chain (ethyl, butyl, hexyl, decyl, and hexadecyl) has been synthesized. Aggregation properties were investigated by absorbance and circular dichroism (CD) spectra. These trismaltohexaosylated tetraphenylporphyrins exhibited high water solubili…
We report a new strategy for synthesizing temperature-responsive gamma-Fe(2)O(3)-core/Au-shell nanoparticles (Au-mNPs) from diblock copolymer micelles. The amphiphilic diblock copolymer chains were synthesized using reversible addition-fragmentation chain-transfer (RAFT) with a thermally responsive "smart" poly(N-isop…
The hydrothermal reaction of rare earth oxide, CuO, 2,6-pyridinedicarboxylic acid, and 4,4'-bipyridine in the presence of H(3)PO(3) resulted in the formation of a new series of 3d-4f heterometallic coordination polymers [Ln(pydc)(3)Cu(3)(bipy)(3).m(H(2)O)](n) (Ln = Pr (1), Nd (2), m = 5; Ln = Sm (3), Eu (4), Gd (5), T…
Biaxial nematic and biaxial smectic phases were found in a colloidal model system of goethite (alpha-FeOOH) particles with a simple boardlike shape and short-range repulsive interaction. The macroscopic domains were oriented by a magnetic field and their structure was revealed by small angle x-ray scattering. In accor…
We investigate the spin-dependent tunneling properties in a three-terminal III-V-based ferromagnetic-semiconductor heterostructure with a 2.5-nm-thick GaMnAs quantum well (QW) and double barriers. We successfully control the quantum levels and modulate the spin-dependent current with varying the voltage of the electro…
Molecular imaging is a technique for quantifying physiological changes in vivo using imaging probes, or beacons, which can be detected noninvasively. This field of study has advanced rapidly in recent years, in part due to the application of nanotechnology. The versatility of different imaging modalities has been sign…
Understanding the dynamics of exciton quenching in quantum dots (QDs) is essential to their potential applications, such as solar cells and biological imaging. In this work, the competition between electron and energy transfer from excited CdSe QDs to adsorbed rhodamine B (RhB) molecules was examined by time-resolved…
