We report a polyhedral oligomeric silsesquioxane (POSS)-based filler for improving the thermal properties of ionic liquids (ILs). We prepared homogeneous mixtures containing the octa-substituted carboxy-POSS as a filler via a solution process. Initially, it was found that the melting temperatures of the ionic pairs we…
α-MoO3 nanobelts of about 8 nm in thickness, 60 nm in width and 0.7–7.5 μm in length were synthesized through a hydrothermal process. It was found that the pH value and the concentration of the surfactant (P123) played crucial roles in determining the crystal phase and the shape of the MoO3 nanomaterials. Small-sized…
Water-soluble TPPS was found to self-assemble into long nanofibers of ambiguous chirality in organic solvents, while mirror imaged chiroptical nanorods with controlled chirality were formed when (1R,2R)-(-)- or (1S,2S)-(+)-1,2-diaminocyclohexane was involved during the self-assembly.
The aim of this study was to investigate the toxic impacts of titanium dioxide nanoparticles (TiO₂-NPs) on rat kidneys and the possible prophylactic role of either quercetin or idebenone. TiO₂-NPs were administered orally at either 600 mg or 1 g/kg body weight for 5 consecutive days to evaluate dose-dependent toxicity…
In membranes with nematic liquid-crystalline order, there is a geometric coupling between the nematic director and the shape: nonuniformity in the director induces curvature, and curvature provides an effective potential acting on the director. For a closed vesicle, there must be a total topological charge of +2, whic…
Intratumoral transport and binding are important mechanisms that determine the efficacy of cancer drugs. Current drug screening methods rely heavily on monolayers of cancer cells, which overlook the contribution of tissue-level transport and binding. To quantify these factors, we developed a method that couples an in…
This paper reviews recent achievements as to “nuclear-grade” SiC composites in particular for materials-system integration. SiC composite component development are reviewed including VHTR control rod scale model and compact intermediate heat exchanger scale mode by current joining and assembly techniques. Joining meth…
Undoped MSb2O6 (where M = Zn, Cd, Ba) and single and double doped MSb2O6:RE (where RE = Tb(3+) and Eu(3+)) nanophosphors were synthesized through a simple sonochemical process and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-r…
Herein, a new conjugated poly(pyridinium salt), poly{(4,4′-(1,4-phenylene)bis(2,6-diphenylpyridinium))-co-N-butyl-3,6-carbazolylene ditosylate} (Poly1), exhibits aggregation-induced emission (AIE) characteristics. It is weakly emissive in solution but highly luminescent in the aggregate state. A fluorescence turn-on b…
The redox chemistry of a newly synthesized small dendrimer containing six peripheral viologen units and a phosphazene core is described. The one-electron reduction of each viologen (total six electrons) leads to intermolecular dimerization of the reduced viologens borne by the same phosphorous atom, resulting in a col…
The main goal of this research is maximizing the utilization of renewable materials in both the matrix and reinforcement, more importantly exploitation of waste material for biocomposite development and evaluating the mechanical, thermal and water resistance performances. Woven roving and chopped strand mat fiber glas…
A fluorescent labeled Wells-Dawson type POM ({P2W17O61Fluo}) was newly synthesized and characterized by a wide range of analytical methods. {P2W17O61Fluo} was functionalized with fluorescein amine through a stable amide bond, and its long time stability was verified by UV/vis spectroscopic techniques at physiologicall…
We report an ultrasensitive and selective probe for detection of mercuric ions using gold-silver core-shell nanorods as the substrate of surface-enhanced Raman scattering. The detection limit of this probe for mercuric ions can be as low as 1 pM. The efficiency of this probe in complex samples was evaluated by allowin…
A facile generic strategy of combining template assisted and solvothermal alcoholysis is employed to prepare cage-bell Pd@CeO2 nanoparticle aggregates as catalysts for the low-temperature oxidation of CO. The synthetic parameters are regulated to control the size of the as-prepared CeO2 mesospheres. The activities of…
Nanopolyaniline/p‐type porous silicon (NPANI/PSi) heterojunction films were chemically fabricated via in situ polymerization. The composition and morphology of the nanopolymer were confirmed using Fourier transform infrared, scanning electron microscopy, UV‐visible, and transmission electron microscopy techniques. The…
Effects on the optical, electrical, and photocatalytic properties of undoped CuS thin films nanodisks vacuum annealed at different temperatures were investigated. The chemical bath prepared CuS thin films were obtained at 40°C on glass substrates. The grain size of<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathM…
Nanomachines activated by a pH change can be combined with polymer coatings on mesoporous silica nanoparticles to produce a new generation of nanoparticles for drug delivery that exhibits properties of both components. The nanovalves can trap cargos inside the mesoporous silica nanoparticles without premature release…
Stable bulk glasses from the quaternary system Cu–As–Te–Se are investigated for thermoelectric applications. These materials exhibit a low thermal conductivity κ ∼ 0.3 W K−1 m−1 which is appealing for raising the thermoelectric figure of merit ZT. The addition of small amounts of selenium within the telluride amorphou…
A single-layer graphene sheet represents the thinnest transparent conductive electrode for planar photovoltaic devices on both rigid and flexible substrates. Here, we demonstrate fiber-shaped polymer solar cells wrapped by a Au nanoparticle-adsorbed graphene single-layer sheet as a counter electrode, and show cell eff…
We have demonstrated that wurtzite CuInS2 nanowires could be synthesized in solution via Ag2S-catalyzed growth. It is confirmed that Ag2S nanocrystals are formed firstly and act as catalysts for the growth of the CuInS2 nanowires by monitoring the structures and morphologies of the Ag2S nanocrystals and CuInS2 nanowir…
