We present the first evidence for the synthesis of nanotwinned polyhedral 26-facet Cu7S4 microcages enclosed within polycrystalline shells. The photocatalytic superiority of these cages is attributed to the presence of a larger number of nanotwinned building blocks, which exhibited higher adsorption ability and cataly…
Significantly enhanced temporal stability of poled electro-optic (E-O) polymers could be achieved by inserting a thin sol–gel derived titanium dioxide (TiO2) barrier layer in the high electric field poling process. The resulting poled film can retain >90% of its original r33 value (169 pm V−1 at 1310 nm) after being a…
This chapter introduces the principles and development procedures for physiologically based pharmacokinetic (PBPK) models, and their application for nanoparticle toxicity studies. PBPK models describe the concentration-time or mass-time profiles of chemicals or nanoparticles in individual tissues and organs within the…
A novel pyrene covalently-attached polyoxometalate (POM) hybrid has been synthesized and fully characterized. The attractive electronic and photophysical properties of pyrene derivatives make the hybrid promising for studying and understanding electron transfer mechanisms in organic-functionalized POMs. The hybrid has…
A new photochromic system 2o/2c based on a highly photostable terrylene bisimide (TBI) fluorophore and a diarylethene (DAE) photochrome has been synthesised and its photoswitching properties have been investigated by UV/vis absorption and fluorescence spectroscopy and by cyclic voltammetry. Our detailed studies reveal…
A new type of bismuth silicate glass (Bi2O3-SiO2-ZnO-Al2O3-La2O3) doped with Tm2O3 is prepared by melt-quenching method. The thermal stability of the glass is examined by differential scanning calorimetry. No crystallization peak is found. Using the absorption and emission spectra, the absorption and emission cross-se…
This study reports the mechanical response of distinct carbon nanotube (CNT) morphologies as revealed by flat punch in situ nanoindentation in a scanning electron microscope. We find that the location of incipient deformation varies significantly by changing the CNT growth parameters. The initial buckles formed close…
Metathesis reaction of LLnCl(THF)(2) [L = (Me(3)SiNC(C(6)H(5))N)(2)(CH(2))(3)] with NaBH(4) in a 1 : 1.5 molar ratio in THF (THF = tetrahydrofuran) at 60 °C afforded the monoborohydride LLn(BH(4))(DME) [Ln = Y (1), Nd (2), Sm(3) and Yb(4)] crystallized from DME solution (DME = dimethoxyethane). Crystal structure analy…
Three new organic–inorganic hybrid compounds based on copper-bis(triazole) complexes and Keggin-type polyoxometalates (POMs) with different negative charges, [Cu(I)BBTZ]3[PMo12O40] (1), [Cu(I)BBTZ][Cu(I)(HBBTZ)2][SiMo12O40]·2.5H2O (2) and [Cu(I)BBTZ]6[SiWV2WVI10O40]·2H2O (3) (BBTZ = 1,4-bis(1,2,4-triazol-1-ylmethyl)be…
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…
