The electronic structure, magnetism and half-metallicity of quaternary Heusler compounds NbCoCrAl and NbRhCrAl were investigated theoretically by using first-principles calculations. It was found that the equilibrium lattice constants of NbCoCrAl and NbRhCrAl compounds are 6.02 Å and 6.18 Å, respectively. The total ma…
, was also achieved. Compared with the conventional conducting polymer materials, the 3D RGO/S-PANI composite presented more reliable rate capability and cycling stability. Moreover, S-PANI possesses excellent processability, thereby revealing its enormous potential in large scale production. We anticipate that the so…
The contrasting rare earth ion substitution in Ce <sub>0.9−x</sub> RE <sub>x</sub> O <sub>2−δ</sub> :0.1Eu <sup>3+</sup> elucidates the influence of the local structure and defect formation on photoluminescent properties.
) in the kinetics of microstructural degradation are investigated for porous nickel (Ni)/ceria gadolinium oxide (CGO) anodes, to understand the microstructural evolution in SOFC cermet anodes. A combined system of Focused Ion Beam (FIB) and Scanning Electron Microscope (SEM) tomography was used to analyze various anod…
The current investigation achieves photochemical upconversion in pure water using combinations of water soluble Ru( <sc>ii</sc> ) metal-to-ligand charge transfer (MLCT) sensitizers in concert with 9-anthracenecarboxylate (AnCO <sub>2</sub> <sup>−</sup> ) and 1-pyrenecarboxylate (PyCO <sub>2</sub> <sup>−</sup> ).
The novel red phosphor K <sub>2</sub> LiGaF <sub>6</sub> :Mn <sup>4+</sup> , which exhibits a broadband excitation extending from 300 to 500 nm and an ideal narrow band emission centered at 630 nm, is a promising red phosphor candidate for application in WLEDs.
The confluence of therapeutics and diagnostics based on the advantages of nanotechnology offers significant opportunities for personalized and precision medicine. Intelligent nanotheranostics based on bioresponsive systems have recently emerged and offer the promise of high specificity and efficiency via "on-demand" a…
We report the synthesis and magnetic properties of a series of new organometallic homoleptic complexes Li(DME) <sub>3</sub> [Ln(DAD) <sub>2</sub> ] (Ln = Dy ( <bold>1a</bold> , <bold>1b</bold> ), Tb( <bold>2</bold> ), and Er( <bold>3</bold> )).
Lanthanide-doped luminescent nanoparticles with both emission and excitation in the near-infrared (NIR-to-NIR) region hold great promise for bioimaging. Herein, core@shell structured LiLuF4:Nd@LiLuF4 (named as Nd@Lu) nanoparticles (NPs) with highly efficient NIR emission were developed for high-performance in vivo bio…
Solvent evaporation is used for fabrication of nanoporous fibers by electrospinning, where multiple solvents are used. Pore size and distribution can be con-trolled by the fractions of the spun solution. An experiment was carefully designed, where polysulfone and poly(lactic acid) were dissolved in a binary solvent of…
The oxygen vacancy defects of amorphous SiO2 (a-SiO2) in different charge states are investigated by the periodic density functional theory. Five types of the positively charged configurations are obtained including the dimer, forward-oriented, puckered 4×, 5× and back-projected unpuckered configurations. The energy,…

We propose a design of a metamaterial based sensor to be used in various applications including micro-fluid, strain and rotation sensing. The structure has a simple geometry composed of a single circular split ring resonator (CSRR) and it is possible to adjust the resonance frequency in the region of desired band. The…
A pH and redox dual-sensitive biodegradable polysaccharide, succinic acid-decorated dextran-g-phenylalanine ethyl ester-g-cysteine ethyl ester (Dex-SA-l-Phe-l-Cys), was synthesized to load doxorubicin hydrochloride (DOX·HCl). The DOX-loaded nanoparticles, which were prepared in aqueous solution and free of organic sol…
