Y2Ti2O7:Er(3+)/Yb(3+) (EYYTO) phosphors co-doped with Li(+) ions were synthesized by a conventional solid-state ceramic method. X-ray diffraction studies show that all the Li(+) co-doped EYYTO samples are highly crystalline in nature with pyrochlore face centred cubic structure. X-ray photon spectroscopy studies revea…
To address the issues such as low ionic conductivity, poor electrode kinetics and cyclic stability, the strategy of combining carbon-based materials with transition metal oxide (TMO) is adopted. In this article, the preparation of CuO/reduced graphene oxide (RGO) nanocomposite electrodes by a simple, low cost hydrothe…
Upconversion fluorescence has been frequently cited as an important feature in carbon nanodots (CNDs) and graphene quantum dots (GQDs); and some mechanisms and potential applications have been proposed. Contrary to such a general belief, we demonstrate in this report no observable upconversion fluorescence based on fi…
Magnetic resonance imaging (MRI) is a popular imaging technique in medical diagnostics. With the development of contrast agents, interest in its applications has grown tremendously. Significant effort has been made in order to identify the most important parameters that enhance the relaxation efficiency of MRI probes.…
T-Nb 2 O 5 /graphene nanocomposites were fabricated and then paired with mesoporous carbon electrodes to construct the asymmetrical supercapacitors with high energy and power densities.
A series of hypercrosslinked microporous organic copolymer networks was synthesized via Friedel–Crafts alkylation of tetraphenylethylene (TPE) and/or 1,1,2,2-tetraphenylethane-1,2-diol (TPD) promoted by anhydrous FeCl 3 .
Nanocomposites containing soft and hard magnetic phases have attracted immense attention for energy-related and biomedical applications. With exchange coupling between nanoscale grains in the composites, magnetization of the soft magnetic phase can rotate coherently with that of the hard magnetic phase. In particular,…
A straightforward postsynthetic lanthanide functionalization strategy is developed for fabricating highly sensitive ratiometric luminescent nanothermometers based on nanosized MOFs, which highlights the ability of a broad range of nanosized MOFs to construct nanothermometers.
The production of two-dimensional rhenium disulfide (ReS2) nanosheets by exfoliation using lithium intercalation is demonstrated. The vibrational and photoluminescence properties of the exfoliated nanosheets are investigated, and the local atomic structure is studied by scanning and transmission electron microscopy. T…
BACKGROUND: A standard short-term inhalation study (STIS) was applied for hazard assessment of 13 metal oxide nanomaterials and micron-scale zinc oxide. METHODS: Rats were exposed to test material aerosols (ranging from 0.5 to 50 mg/m3) for five consecutive days with 14- or 21-day post-exposure observation. Bronchoalv…
Screen-printed polymer thermoelectric devices provided sufficient power to illuminate light-emitting diodes.
Porous carbon nanofibers were prepared by electrospinning using coal as the raw material. The activated carbon fiber mat is a promising candidate for the electrode of supercapacitors.
Zinc oxide nanoparticles (ZnO-NPs) are known to be one of the multifunctional inorganic compounds which are widely used in everyday applications. This study aims to fabricate ZnO-NPs using grapefruit (Citrus paradisi) peel extract with particle size ranging from 12 to 72 nm. Structural, morphological, and optical prop…
A strategy of using controlled self-assembly of caspase-3/7-sensitive Gd-based MR contrast agent is demonstrated for non-invasive monitoring of drug-induced tumor cell death in mice.
Remarkable chemical adsorption of CO 2 has been achieved in titanate with significant concentration of oxygen vacancies towards the efficient direct CO 2 electrolysis in solid oxide electrolysers.
Research on composites/blends containing polyaniline (PANI) has attracted numerous scientists and engineers due to their excellent adhesion and anticorrosive properties. Nano-structured PANI composites and matrix resins play a key role in physical and anticorrosive performance. This paper reviews the synthesis, growth…
Three CuO/CeO2 catalyst with different morphologies of ceria, namely nanospheres, nanorods and nanocubes, were synthesized and used to catalyze the water-gas shift (WGS) reaction. The reactivity tests showed that the Cu supported on the ceria nanospheres exhibited both the highest activity and superior stability when…
The determination of crystal structures and the solid-to-solid phase transition mechanisms are two important and related subjects in material science. Here we develop an unbiased general-purpose potential energy surface (PES) searching method, namely, SSW-crystal method, for prediction of both the crystal structure an…
Progressive restrictions on the use of toxic chromate-based corrosion inhibitors present serious technical challenges.
