Photoluminescent cadmium sulphide (CdS) quantum dots (QDs) were successfully obtained by a single-source route via a non-injection one-pot approach using octadecene (ODE) as a non-coordinating solvent and myristic acid (MA) as capping agent. The synthetic scheme makes use of two metal-organic molecules belonging to th…
The terrestrial slug Arion subfuscus produces a defensive secretion that is sticky and tough, despite being a dilute gel. It is unusual in having high stiffness for a gel, yet retaining the high extensibility typical of mucus. In tensile tests, it sustains an average peak stress of 101 kPa, and fails at an average str…
The fabrication of anode supported single cells based on BaZr 0.8 Y 0.2 O 3-δ (BZY20) electrolyte is challenging due to its poor sinteractive nature. The acceleration of shrinkage behavior, improved sinterability and larger grain size were achieved by the partial substitution of Zr with Ni in the BZY perovskite. Phase…
Herein we report a novel strategy involving the hybridization of nanoporous NiO flakes with graphene oxide (GO) sheets. The as-prepared flake-like nickel cyano-bridged coordination polymers (NiCNNi) are hybridized with GO sheets and thermally treated in air, so the organic materials can be removed without affecting th…
A series of pentacoordinate Ni(ii) complexes of the general formula [Ni(L5)] () with various pentadentate Schiff base ligands H2L5 (originating in a condensation of aromatic ortho-hydroxy-aldehydes and aliphatic triamines) was synthesized and characterized by X-ray structure analysis and magnetometry. The alternations…
Multiferroic bismuth ferrite (BFO) and Ni-doped bismuth ferrites, with perovskite structure, were synthesized by chemical route at the temperatures ranging from 500 to 600 ?C in controlled atmosphere. The structural phase analysis of materials was identified by XRD and crystallite size was calculated from the half wid…
Tumor-homing and pH-responsive polypeptide-drug nanoparticles for targeted cancer therapy are precisely designed by site-specific drug conjugation to a bioactive and well-defined elastin-like polypeptide through an acid-labile linker. In a murine cancer model, these nanoparticles show significantly better anti-tumor e…
A new langbeinite-type phosphate KSrSc2(PO4)3 has been synthesized by conventional high temperature solid state reaction. Rietveld structure refinement, a field emission scanning electron microscope, photoluminescence spectra, quantum efficiency as well as lifetimes were used to characterize the samples. Structure ref…
A series of epitaxial V1-xWxO2 (0 ≤ x ≤ 0.76%) nanocrystalline films on c-plane sapphire substrates have been successfully synthesized. Orbital structures of V1-xWxO2 films with monoclinic and rutile states have been investigated by ultraviolet-infrared spectroscopy combined with first principles calculations. Experim…
UV-responsive microcapsules were prepared via O/W Pickering emulsion templates using SiO2 and TiO2 nanoparticles as Pickering agents.
We report on a robust nanotemplating approach to synthesize plasmonic multilayered core-satellite (MCS) nanoassemblies. Templated with gold nanorods, ultrathin Au/Ag alloy cages and satellite gold nanoparticles can be constructed sequentially by galvanic replacement reactions and electrostatic self-assembly, respectiv…
CdO nanoparticles obtained from a thermal decomposition, show a room temperature ferromagnetism due to the cadmium and oxygen defects.
Co 3 O 4 -modified Prussian blue nanocubes (PB@Co 3 O 4 ) were obtained by using a water-bath method and were found to exhibit both intrinsic oxidase-like and peroxidase-like activities.
A polythiophene/TiO 2 particle composite was synthesized by a facile and green method in aqueous medium to adsorb Pb 2+ ions from aqueous solution, and both of synthesis and adsorption mechanism were proposed.
Pseudomonas moraviensis stanleyae was recently isolated from the roots of the selenium (Se) hyperaccumulator plant Stanleya pinnata. This bacterium tolerates normally lethal concentrations of SeO3(2-) in liquid culture, where it also produces Se nanoparticles. Structure and cellular ultrastructure of the Se nanopartic…
The discovery of graphene some ten years ago was the first proof of a free-standing two-dimensional (2D) solid phase. Here, using quantum molecular dynamics simulations of nanoscale gold patches suspended in graphene pores, we predict the existence of an atomically thin, free-standing 2D liquid phase. The liquid phase…
This fluorescence sensing system showed excellent performance and could be applied to the determination of S 2− in natural water samples.
Two solvated cobalt(ii) terpyridine complexes, [Co(MeO-terpy)2](BF4)2·H2O (·H2O) and [Co(MeO-terpy)2](BF4)2·acetone (·acetone) were prepared. Annealing each of these complexes resulted in the formation of two desolvated species, and , respectively. ·H2O and exhibited two-step and gradual SCO. The compound ·acetone has…
Conductivity enhancement of PEDOT:PSS thin films by hydroiodic acid treatment and their application in organic solar cells.
Facile synthesis of graphene quantum dots using an acid-free oxone oxidant and graphene oxide was successfully developed by sono- and photo-oxidation reactions.
