A highly efficient and stable inverted organic photovoltaic cell has been demonstrated by incorporating a zinc oxide (ZnO)/conjugated polyelectrolyte (CPE) stacked structure as an electron-transporting layer. The CPE not only improved the electron collection efficiency in inverted devices but also smoothened the ZnO s…
Mo3Sb7 thin films prepared by magnetron sputtering are evaluated as an anode material for Li-ion and Na-ion batteries. The as deposited films are amorphous and composed of small agglomerated domains with an overall Sb/Mo ratio of 2.34 that is almost identical to the ratio measured for the starting powder and the expec…
The highly porous (3,24)-connected framework NOTT-122 incorporates a C3-symmetric angularly connected isophthalate linker containing 1,2,3-triazole rings and shows body-centered tetragonal packing of [Cu24(isophthalate)24] cuboctahedra. This unique packing, coupled with the high density of free N-donor sites, is respo…
The abilities of two naphthalimide derivatives with a methacryloyl group to initiate, when incorporated in multi-component systems, a ring-opening polymerization of epoxides and a radical polymerization of acrylates under different irradiation sources (e.g. very soft halogen lamp irradiation, laser diode at 457 nm, la…
We report a facile strategy to synthesize SnO2 nanoparticles dispersed nitrogen doped graphene (SnO2/NG). Nitrogen doping of graphene was carried out by the pyrolysis of polypyrrole coated poly(sodium 4-styrenesulfonate) functionalized graphene. The SnO2 nanoparticles are dispersed over nitrogen doped graphene by a mo…
We presented a novel and simple approach towards white photoluminescence and electroluminescence based on blue emissive materials through controlled acid protonation; and this methodology has potential applicability in fabricating white OLEDs considering the simplicity of both material design and device fabrication.
A composite of modified graphene and LiFePO4 has been developed to improve the speed of charging-discharging and the cycling stability of lithium ion batteries using LiFePO4 as a cathode material. Chemically activated graphene (CA-graphene) has been successfully synthesized via activation by KOH. The as-prepared CA-gr…
The intrinsic Raman signals provide the potential of graphene oxide (GO) for cellular imaging. Herein, novel surface-enhanced Raman scattering (SERS) labels based on GO-Ag nanoparticle (NP) composites are developed for fast cellular probing and imaging. The optimum SERS signals of the hybrids can be well controlled by…
The current Si-based photovoltaic devices require high-quality raw materials and intricate processing techniques to construct complex device structures; further improvement in efficiency and a drastic decrease in cost are thus highly desired to promote their extensive applications. In this work, we conducted a compreh…
This feature article reviews some titanate-based adsorbents for the removal of radioactive wastes (cations and anions) from water. At the beginning, we discuss the development of the conventional ion-exchangeable titanate powders for the entrapment of radioactive cations, such as crystalline silicotitanate (CST), mono…
A homochiral MOF membrane was successfully and facilely synthesized using an in situ growth method, which had the advantages of cheap raw materials, simple operation and high thermal stability. A diol isomer mixture was used to test the separation efficiency of the membrane at different temperatures and pressures.
Herein, we demonstrate the design and fabrication of a well dispersed triplex Ag@SiO2@TiO2 core-shell photocatalyst, which shows enhanced visible light photocatalytic activity due to the plasmonic field of the inner Ag core. The SiO2 interlayer is coated on the Ag core by a sol-gel process to prevent oxidation of Ag a…
The electrochemistry of the Ru-containing polyoxometalate (POM) water oxidation molecular catalyst, Rb8K2[{Ru4O4(OH)2(H2O)4}(γ-SiW10O36)2]10− (Rb8K2-1), has been studied by cyclic and rotating disk electrode voltammetric methods in aqueous media under acidic and neutral pH conditions using bare glassy carbon (GC) and…
A novel ZnO/reduced graphene oxide (RGO)/CdS heterostructure was successfully synthesized via a facile three-step solution method. RGO serves as an interlayer between ZnO nanowires and CdS quantum dots (QDs), which provides a high speed charge transfer channel, leading to an enhanced charge separation efficiency. Unde…
Higher alcohol synthesis (HAS) from syngas has attracted much attention and Cu-modified Fischer–Tropsch (FT) catalysts exhibited promising catalytic performance for HAS. In this paper, three model modified FT catalysts, CuFe, CuCo and CuNi nanoparticles, were synthesized by co-reduction method for the comparison of th…
Silver(I) and gold(I)-N-heterocyclic carbene (NHC) complexes bearing a fluorescent anthracenyl ligand were examined for cytotoxicity in normal and tumor cells. The silver(I) complex exhibits greater cytotoxicity in tumor cells compared with normal cells. Notably, in cell extracts, this complex determines a more pronou…
Polymer chain architecture is a critically important chain parameter governing intrinsically the properties and applications of polymers. The rapid developments in "living"/controlled polymerization techniques, particularly the controlled radical polymerization techniques, in the past two decades have enabled the prec…
MnFe(2)O(4)-graphene nanocomposites (MnFe(2)O(4)-GNSs) with enhanced electrochemical performances have been successfully prepared through an ultrasonic method, e.g., approximate 1017 mA h g(-1) and 767 mA h g(-1) reversible capacities are retained even after 90 cycles at a current density of 0.1 A g(-1) and 1 A g(-1),…
Graphene oxide (GO) is known to interact with single-stranded nucleic acids through pi-stacking interactions and hydrogen bonds between the nucleobases and the hexagonal cells of GO. It also quenches the fluorescence when the fluorophore comes near to the GO mesh. When single-stranded (ss) regions of either DNA or RNA…
Amphotericin B and itraconazole were used to demonstrate that ionic liquids can be designed or chosen to provide tunable hydrophilicity in one ion and lipophilicity in the other allowing one to match the structural requirements needed to solubilize poorly water soluble active pharmaceutical ingredients. These liquid,…
