PURPOSE: The objective of this study was to develop a novel folate receptor-targeted drug delivery system for retinoblastoma cells using doxorubicin (DOX) as a model drug. METHODS: Biodegradable DOX-loaded poly(d,l-lactide-co-glycolide)-poly(ethylene glycol)-folate (PLGA-PEG-FOL) micelles (DOXM) were prepared with var…
This paper presents an energy storage and management system to achieve long lifetime and miniaturization for autonomous wireless sensor nodes, which can be used in communication network for microgrids. The system employs supercapacitors to form a multienergy-source structure, and thus features multidirectional power d…
We report on conversion of near-ultraviolet and visible radiation ranging from 250 to 500 nm into near-infrared emission by a Ca(8)Mg(SiO(4))(4)Cl(2): Eu(2+), Er(3+) phosphor. Efficient 1530-1560 nm Er(3+) emission ((4)I(13/2)-->(4)I(15/2)) was detected under the excitation of Eu(2+) (4f?5d) absorption band as a resul…
Nearly single-phased FeVSb half-Heusler compound thermoelectric materials with fine grains of diameter 100–200 nm were prepared from their elemental powders by combining mechanical alloying (MA) and spark plasma sintering. The resultant bulk samples showed a relatively low room-temperature electrical resistivity on th…
Lanthanide‐doped thoria is relevant both to nuclear energy and to solid oxide fuel cell technology. It is also a simple model system in which oxygen vacancy concentration is directly proportional to doping with no complication from oxidation–reduction reactions, ordered phases, or phase transitions in the tetravalent…
The construction of a new series of dendritic tris(crown ether) hexagons via coordination-driven self-assembly is described. Combining 120° crown ether-containing diplatinum(II) acceptors with 120° dendritic dipyridyl donors in a 1:1 ratio allows for the formation of a new family of dendritic triple crown ether deriva…
We report neutron-scattering studies on static magnetic orders and spin excitations in the Fe-based chalcogenide system ${\text{Fe}}_{1+\ensuremath{\delta}}{\text{Se}}_{x}{\text{Te}}_{1\ensuremath{-}x}$ with different Fe and Se compositions. Short-range static magnetic order with an in-plane wave vector near the (0.5,…
Abstract Gold nanoparticles have been deposited on three kinds of carbon nanotubes (CNTs), including nitrogen‐doped CNTs, by three different methods, namely, impregnation, organometallic decomposition, and deposition–precipitation. The choice of the gold precursor, the support, and the preparation procedure is critica…
BaSi 2 O 2 N 2 :Ce 3+ ,Eu 2+ phosphors were successfully synthesized via the solid‐state reaction method. Their luminescence properties were experimentally investigated and qualify them for further consideration as components in white light‐emitting diodes. In particular, BaSi 2 O 2 N 2 :Eu 2+ phosphors have an effici…
Dense ceramics of (1− x )BaTiO 3 − x LaYO 3 (LBTY) (0≤ x ≤0.50) have been fabricated by the conventional solid‐state route. Phase purity and crystal structure of LBTY ceramics were investigated using a combination of X‐ray diffraction (XRD), electron diffraction (ED), and Raman spectroscopy. XRD analysis shows the tet…
Topical administration of levothyroxine (T₄) helps to reduces deposits of adipose tissue on skin. The question is whether topical application of T₄ could lead to systemic effects. In the present study a series of nanofibrous membranes were electrospun into blends of poly vinyl alcohol (PVA) and poly-N-isopropylacrylam…
We report the synthesis of highly ordered mesoporous frameworks consisting of nanocrystalline Co 3 O 4 and Keggin-type tungstophosphoric acid (HPW 12 O 40, HPW) compounds using the hard-templating method. The resulting materials feature a Co 3 O 4 /HPW solid solution structure with different HPW loadings, i.e., 6, 11,…
Abstract In this research, polypropylene/wood‐flour composites (WPCs) were blended with different contents of wood and/or maleated polypropylene (MAPP) and clay. We found that the addition of MAPP or clay in the formulation greatly improved the dispersion of the wood fibers in the composite; this suggested that MAPP o…
We have investigated, using atomistic molecular dynamics simulations, the high temperature molecular organization of the linear oligothiophene α-sexithienyl (T6), well known for its organic electronics applications. We have found a smectic and a nematic liquid crystalline phase in the same temperature range where they…
A series of poly(ethylene glycol- co -isopropylidene glyceryl glycidyl ether) (P(EO- co -IGG)) random copolymers with different fractions of 1,2-isopropylidene glyceryl glycidyl ether (IGG) units was synthesized. After acidic hydrolysis a new type of “functional PEGs”, namely poly(ethylene glycol- co -glyceryl glycero…
Electrodes featuring subnanometer pores are favorable to the capacitance and energy density of supercapacitors. However, there is an energy penalty to enter subnanometer pores as ions have to shed part of their solvation shell. The magnitude of such an energy penalty plays a key role in determining the accessibility a…
Y 2 O 3 –MgO composite nanopowder with a volume ratio of 50:50 was synthesized using a sol–gel combustion process. X‐ray diffraction analysis of the as‐synthesized nanopowder shows phase pure Y 2 O 3 and MgO with a cubic crystal structure and crystalline size ∼15 nm. The fully dense Y 2 O 3 –MgO nanocomposites were pr…
Several oxide ceramics, notably ZnO and TiO 2 are known to catalyze decomposition of organic molecules in water under ultraviolet (UV) irradiation. Here we describe fabrication of highly flexible ZnO‐based hierarchical nanostructure obtained by growing radially oriented ZnO nanowires on poly‐ l ‐lactide nanofibers. Ut…
In this study, we investigated optical performance of a biosensor based on the phenomenon of localized surface plasmon resonance (LSPR) in spherical Au nanoparticles, covered by a dense monolayer of globular biomolecules. Theoretical approaches used include Mie theory for a coated spherical particle, electron relaxati…
To elaborate on superhydrophobic surfaces, we report the electrochemical synthesis, surface morphology, and wettability of hydrocarbon conductive polymer films obtained by the electrodeposition of polythiophene, poly(3,4-ethylenedioxythiophene) (i.e., PEDOT), and poly(3,4-ethylenedioxypyrrole) (i.e., PEDOP) derivative…
