Surface enhanced Raman scattering (SERS) is a signal-increasing phenomenon that occurs whenever Raman scattering on a metal surface is enhanced many orders of magnitude. Recently SERS has received considerable attention due to its ultrasensitive multiplex imaging capability with strong photostability. It provides rich…
With the rapid development of nanotechnology and widespread use of nanoproducts, concerns have arisen regarding the ecotoxicity of these materials. In this paper, the photosynthetic toxicity and oxidative damage induced by nano Fe3O4 on a model organism, Chlorella vulgaris (C. vulgaris) in aquatic environment, were st…
Two triarylboron-functionalized carboxylate ligands have been found to be highly effective in selective activation of Tb(III) and Eu(III) emission and enable the use of the Tb(III) and Eu(III) complexes as highly effective luminescent indicators for F(-) and CN(-) in solution and on a solid substrate.
A facile solvothermal approach was used to synthesize monodispersed ultrathin GdF3 nanowires via an oriented attachment mechanism. Gadolinium nitrate acted as the Gd source, n-octylamine and oleic acid as capping ligands, and n-octanol as solvent. The phase and morphology of the nanowires were characterized by powder…
We investigate the thermodynamics and percolation regimes of model binary mixtures of patchy colloidal particles. The particles of each species have three sites of two types, one of which promotes bonding of particles of the same species while the other promotes bonding of different species. We find up to four percola…
High-performance hybrid solar cells (HSCs) based on P3HT : CdSe QD blends are achieved through post-deposition ligand exchange by n-butanethiol (n-BT) with a high power conversion efficiency of 3.09%. The mechanism by which n-BT modifies the surface structures of CdSe QDs and thus improves the HSCs performance is inve…
Chemical functionalization of multiwalled carbon nanotubes (MWCNTs) increases their solubility, dispersion, and biological applications. Since there are only a few studies on the toxicity of functionalized MWCNTs, we investigated the cytotoxic and genotoxic‐oxidative effects of OH‐functionalized MWCNTs on human lung e…
The types and distribution of Al-Mn phases in semi-continuous casting AZ61 magnesium alloy has been investigated in detail by microstructure observation, component analysis, and thermodynamic calculation. The results showed that there were two types of compounds in the AZ61 alloy, Al8Mn5 and Al11Mn4. The former existe…
Magnetic 8 nm Fe(3)O(4) nanoparticles (NPs) were synthesized and modified with dopamine (DPA) and polyethylene glycol (PEG) diacid. The water soluble Fe(3)O(4)-DPA-PEG NPs were then conjugated with the fluorescent Eu(iii) complex of tris(dibenzoylmethane)-5-amino-1,10-phenanthroline (BMAP), giving an Fe(3)O(4)-DPA-PEG…
Wool fiber has a complex hierarchic structure. The multi-scale fibrils are assembled to form a tree-like channel net in wool fiber, providing an efficient heat transfer property. The optimal inner configuration of wool fiber can also be invited to biomimic design of textile fabrics to improve the thermal comfort of cl…
A robust and uniform porphysome, which reveals an efficient photodynamic therapy and contrast-enhanced ultrasonic imaging for theranostic applications, can be fabricated from a 4-armed porphyrin-polylactide conjugate.
A series of high-density double- and single-shelled ZnO/CdSe/CdTe, ZnO/CdTe/CdSe, ZnO/CdTe and ZnO/CdSe nanocable arrays were synthesized as photoanodes by an electrodeposition method using ZnO nanorod arrays as cores. For ZnO/CdSe/CdTe nanocable arrays, the uniform CdSe and CdTe nanoshells were composed of zinc-blend…
We report a simplified method to prepare porous carbon with abundant mesopores and micropores by ambient drying from a resorcinol/formaldehyde-based organic aquagel. Needle-like nano-sized Mg(OH)2 is introduced into the reaction system between resorcinol and formaldehyde, and slightly soluble Mg(OH)2 in the solution a…
Here we report solid oxide cells with thin strontium- and magnesium-doped lanthanum gallate electrolytes that yield power densities of 1.06 W cm−2 at 550 °C and 0.81 W cm−2 at 500 °C when operated on humidified hydrogen and ambient air. Cost-effective ceramic processing and chemical solution impregnation methods were…
The full sets of elastic constants (considering piezoelectric effect, i.e., taking into account piezoelectric coupling effects) and piezoelectric stress constants of five natural tourmaline single crystals of different chemical composition have been determined from room temperature up to ∼900 K employing resonant ultr…
Water-dispersible Re(3+) doped CeF(3) colloidal nanocrystals with well controllable morphology and high crystallinity have been successfully synthesized through a solvothermal process. The TEM images illustrate that the Re(3+) doped CeF(3) nanocrystals are rectangular (or cubic) with a mean diameter of ~10 nm. The exc…
The series of homoleptic tetranuclear [Ln4(L)2(HL)2(NO3)2(OH)2]·2(NO3) (Ln = Nd, 1; Ln = Yb, 2; Ln = Er, 3; Ln = Gd, 4) have been self-assembled from the reaction of the Salen-type Schiff-base ligand H222L with Ln(NO3)3·6H2O (Ln = Nd, Yb, Er or Gd), respectively (H222L: N,N′-bis(salicylidene)cyclohexane-1,2-diamine).…
In order to produce materials with tailored structures and functions via supramolecular self-assembly of molecular precursors in a predictable fashion, it is necessary to develop ‘supramolecular methods’ based on structurally simple ‘supramolecular synthons’. Thus, the formation of one-dimensional aggregates from π-co…
The coordination chemistry of the 2,3-quinoxalinediolate ligand with different lanthanide(III) ions in basic media in air affords a new family of carbonato-bridged M(2)(III) compounds (M = Pr, Gd and Dy), the Dy(2)(III) analogue exhibiting slow magnetic relaxation behaviour typical of single-molecule magnets.
Highly sensitive metal–insulator–semiconductor (MIS) UV photodetectors are demonstrated based on ZnO/SiO2 core–shell nanowires. The MIS devices possess simplicity in material synthesis, technological advantages in the device design and uniqueness in the prevailing mechanism. We propose that inserting an insulating SiO…
