Photoluminescence (PL) fluctuations of single semiconductor nanocrystals (NCs), such as PL blinking and spectral diffusion (SD), reflect the quantum nature of charges in the NCs. Through simultaneous measurements of PL spectra and lifetimes on single CdSe/ZnS NCs, PL of neutral excitons is found to exhibit a unique be…
Abstract Colloidosomes are microcapsules consisting of nanoparticle shells. These microcarriers can be self‐assembled from a wide range of colloidal particles with selective chemical, physical, and morphological properties and show promise for application in the field of theranostic nanomedicine. Previous studies have…
Three-dimensional (3D) macroporous CuO structures composed of ultrathin nanosheets were successfully synthesized by employing a liquid-liquid interface as a two-dimensional (2D) nano-reactor. The macroporous structure helped CuO to retain the exposed surface during reactions, thus significantly enhancing the long term…
The rheological behaviour of organoclay nanocomposites based on natural rubber (NR) and chlorine substituted isobutyl-isoprene rubber (CIIR), was investigated separately. For the study, an organoclay Nanomer I.44P treated with a surfactant containing hydrogenated tallow, quaternary ammonium chloride, was used. The lin…
This communication describes the fabrication of diselenide-containing supramolecular polymers.
This paper shows how it is possible to use Dual Electron Energy Loss Spectroscopy (DualEELS) to digitally extract spectrum images for one phase of interest in a complex nanostructured specimen. The specific cases studied here concern Nb or V precipitates, a few nanometres in size, in high manganese steels. The procedu…
The combination of photodynamic therapy and chemotherapy is a promising strategy to overcome growing problems in contemporary medicine, such as low therapeutic efficacy and drug resistance. Four zinc(II) phthalocyanine-coumarin conjugates were synthesized and characterized. In these complexes, zinc(II) phthalocyanine…
The first-principles calculations are performed to investigate the electronic properties and the atomic mechanism of the single layer MoS2 or WS2 homo-junction structure. The results reveal that both the stability and electronic structure of the homo-junction structure are greatly affected by the type of boundaries, w…
Supported PdAg/NiTi-LDH with rich defective sites was synthesized and exhibited high activity and selectivity in the partial hydrogenation of acetylene.
Carbon nanotubes (CNTs) are considered the most promising candidates to replace Cu and Al in a large number of electrical, mechanical and thermal applications. Although most CNT industrial applications require macro and micro size CNT fiber assemblies, several techniques to make conducting CNT fibers, threads, yarns a…
Confinement can modify the dynamics, the thermodynamics, and the structural properties of liquid water, the prototypical anomalous liquid. By considering a generic model for anomalous liquids, suitable for describing solutions of globular proteins, colloids, or liquid metals, we study by molecular dynamics simulations…
Topologically nontrivial field excitations, including solitonic, linked, and knotted structures, play important roles in physical systems ranging from classical fluids and liquid crystals, to electromagnetism, classic, and quantum field theories. These excitations can appear spontaneously during symmetry-breaking phas…
Leather is a unique consumer material possessing a variety of properties such as strength, viscoelasticity, flexibility, and longevity. However, the use of leather for smart product applications is a challenge since it is an electrically insulating material. Here, we report a simple method to produce conducting leathe…
We have studied the polarity of magnetoresistance (MR) in three types of magnetic junctions. While the NiFe/single layer graphene (SLG)/Co and NiFe/Al 2 O 3 /Co junctions showed spin valve signals with positive MR, the NiFe/Al 2 O 3 /SLG/Co junction revealed negative MR values.
In this work, we present a new, fast and high yield synthesis method for obtaining microcrystalline yttrium orthoferrite YFeO3, based on hydrothermal technique. The advantage of the method consists in the direct crystallization of the material without the necessity of the calcination. The quality of the so-obtained co…
Abstract Biochar is a stabilized carbon-rich product, and has drawn scientists’ interest because of its specific properties and potential use in many environmental areas. It is emphasized that innovative technologies comprised of engineered nanoparticles in conventional biochar systems could ameliorate the functions o…
This work describes a cooperative quantum dot and plasmonic effect on improving the performance of dye synthesized solar cells, in which CdS QDs, gold nanoparticles (GNPs), and gold nanorods (GNRs) are incorporated into the active layer. The cooperative nanoparticles show a superior behavior on enhancing light absorpt…
Six tartrate-bridging rare-earth-substituted polytungstoarsenates [RE2(C4H4O6)(C4H2O6)(As W9O33)]2(18-) (Ho(III) (1), Er(III) (2), Tm(III) (3), Yb(III) (4), Lu(III) (5), and Y(III) (6)) have been synthesized under conventional solution conditions. They have been further characterized by elemental analyses, X-ray powde…
High quality nanocrystalline ZnS thin films were deposited on glass substrates by a chemical bath deposition (CBD) method from an aqueous solution containing triethylamine, as a nontoxic complexing agent for zinc ions, at temperatures ranging from 50 to 90 °C. The effects of the deposition time and temperature on thic…
The ability to detect a few molecules present in a large sample is of great interest for the detection of trace components in both medicinal and environmental samples. Surface enhanced Raman spectroscopy (SERS) is a technique that can be utilized to detect molecules at very low absolute numbers. However, detection at…
