On the basis of the fact of the overexpression of integrins in malignant tumor cells and neovasculature, and the advantage of polymeric micelles (PM) as the drug carriers, a cyclic RGD peptide (cRGDyK) was anchored on the surface of polyethylene glycol-b-poly(lactic-co-glycolic acid) (PEG-b-PLGA) micelles as a ligand…
Despite the fundamental importance of metal surface oxidation in a number of emerging fields such as catalysis, microelectronics, and biosensor technology, a comprehensive picture of the processes leading to the growth of thin oxide layers at low temperature is still lacking. In this work, we employ advanced first-pri…
We study the low-temperature regime of an atomic liquid on the hyperbolic plane by means of molecular dynamics simulation and we compare the results to a continuum theory of defects in a negatively curved hexagonal background. In agreement with the theory and previous results on positively curved (spherical) surfaces,…
We report on a universal technique which allows us to precisely manipulate the diameter of metal nanoparticles in two-dimensional particle arrays. The approach is demonstrated here for hexagonally ordered gold nanoparticle arrays fabricated by means of diblock copolymer micelle lithography (BCML). The particles are us…
In the context, a novel composite synthesis technology is engaged in the preparation of NaRE(MoO 4 ) 2 (RE=Y, La, Nd, Eu, Gd, Tb, Er, and Yb) and Na 5 Lu(MoO 4 ) 4 compounds, which involves a room‐temperature solid‐state reaction and hydrothermal crystallization process. The synthesis mechanism is predicted, indicatin…
We report ferromagnetism in single phase, epitaxial ${\text{In}}_{1\ensuremath{-}x}{\text{Mn}}_{x}\text{Sb}$ alloy films, with $x\ensuremath{\le}0.035$, grown by metalorganic vapor phase epitaxy. The alloy films exhibit well-defined magnetization versus magnetic field hysteresis loops from 4--298 K. High-field magneto…
Abstract Electrospinning technique was used to prepare the nanofibres of pure and Europium (Eu)‐doped titania with Eu content of 3–10%mol. The solution was electrospun in air at room temperature. The obtained fibrous mats were thermally treated at 500 or 1000 °C. Morphology and phase analyses of the resulting fibrous…
Reliable and reproducible p-type doping is the main challenge for fabricating highly efficient ZnO-based light-emitting diodes. During the last few years, the lack of reliable p-type conductivity in ZnO has initiated research concerning the combination of ZnO and other semiconductors, which can then be doped p-type. O…
Samples of 4,4'-bis(3,3,3-tri-d(5)-phenylpropynyl)biphenyl 2, 9,10-bis(3,3,3-tri-d(5)-phenylpropynyl)anthracene 3, 1,4-bis(3,3,3-tri-d(5)-phenylpropynyl)naphthalene 4, and 4,4'-bis(3,3,3-tri-d(5)-phenylpropynyl)-1,1'-binaphthyl 5 were prepared via a Sonogashira coupling of 3,3,3-tri-d(5)-phenylpropyne 7 and the approp…
A novel lanthanide probe was designed, synthesized, and employed for a sensitive and reliable assay of acrolein based on time-resolved luminescence measurement, which suppresses the background signal of serum.
ZnO nanorods arrays are respectively prepared under different vapor pressures with opening (OZN) or sealing (SZN) of the beaker. The results from time-resolved photoluminescence measurements indicate that sealing the beaker during the growth process can effectively suppress the surface recombination of ZnO nanorods, a…
Ferromagnetism is found in nanocrystalline Zn/ZnO core-shell structures prepared by sputtering pure Zn with subsequent oxidation. The saturation magnetization (M(S)) of the passivated ZnO shells increases with decrease in average particle size (d). The Curie temperature of the samples is above 400 degrees C. It is fou…
This work shows that the combination of first-principles calculations and (51)V NMR experiments is a powerful tool to elucidate the location of surface hydroxyl groups and to precisely describe the hydrogen bond network in the complex decavanadate cluster Cs(4)[H(2)V(10)O(28)].4H(2)O, enhancing the strength of NMR cry…
The present work describes a comprehensive design and scalable micro-fabrication technique for the production of novel 3D cathodes, consisting of chemical-vapor-deposition-grown high-density multi-wall carbon nanotubes along the walls of alumina microchannels. Under high DC and AC electric fields, the 3D cathodes disp…
The concentration and pressure dependent luminescence properties of the Tb(3+) ions in a lithium fluoroborate glasses have been studied by analyzing the deexcitation processes of the (5)D(4) level at ambient conditions as well as a function of pressure up to 35 GPa at room temperature. The luminescence spectra of Tb(3…
AgPb 10 SbTe 12 crystals with nanocubic and flower-like morphologies have been successfully fabricated by a facile solution route. The sizes and morphologies of AgPb 10 SbTe 12 were examined in relation to reaction temperature, the molar ratio of KOH/Pb(Ac) 2, polyvinyl pyrrolidone (PVP), and solvents. A surface-prote…
Abstract We report, herein, on the preparation of polyaniline (PANi)/porous silicon (PSi) hybrid material. High surface area PSi substrates were obtained by electrochemical etching of crystalline silicon in HF‐based solutions. The freshly prepared PSi surface was first oxidized by UV/ozone and then reacted with 3‐brom…
Two novel aromatic diamine monomers, Bis-4,4′[(4-aminophenyl-2,2′-isopropylidene phenyloxy)] diphenylsulfone and Bis-4,4′[(4-aminophenyl-2,2′-isopropylidene phenyloxy)] benzophenone were synthesized and characterized by IR and 1 H-NMR. A series of processable polyimides were prepared by polycondensation of diamines wi…
High-purity hydrogen continues to receive attention as a promising energy source for fuel cells in portable power applications. On-demand hydrogen generation via fuel reforming offers a convenient alternative to hydrogen storage, but the concomitant CO generation is deleterious to the fuel cell catalyst. Of the possib…
We propose a photoelastic pressure sensor using a liquid crystal (LC) tunable fiber polarizer. The polarizer contains an etched single-mode fiber sealed in an LC cell. A low-index LC is used as a tunable birefringent cladding of the fiber. Any electric-field-induced LC director reorientation may thus affect the fiber'…
