We report a microfluidic approach for de novo protein structure determination via crystallization screening and optimization, as well as on-chip X-ray diffraction data collection. The structure of phosphonoacetate hydrolase (PhnA) has been solved to 2.11 Åvia on-chip collection of anomalous data that has an order of m…
Metal(II) formates (Co and Ni) show a significantly larger heat of adsorption for xenon than krypton across all loadings due to size selectivity in the primary adsorption site.
Flower-like BaTiO3/Fe3O4 hierarchically structured particles composed of nano-scale structures on micro-scale materials were synthesized by a simple solvothermal approach and characterized by the means of X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), magnet…
New aluminium complexes containing bis-BTP ligands (BTP = N,O-bidentate benzotriazole phenoxide) were synthesized and structurally characterized. Amine elimination of Al(NMe2)3 with (R)BTP-H ligands ((CMe2Ph)BTP-H = 2-(2H-benzotriazol-2-yl)-4,6-bis(1-methyl-1-phenylethyl)phenol, (t-Bu)BTP-H = 2-(2H-benzotriazol-2-yl)-…
A nice visible light responsive C-doped NaTaO3 (C-NaTaO3) particle has been successfully prepared by a facile solvothermal method using water-ethylene glycol mixed solutions as solvent. The results presented that the carbon could be easily incorporated in NaTaO3 from ethylene glycol during a solvothermal reaction, fin…
A series of low band gap photovoltaic copolymers containing benzodifuran-alt-thieno[3,4-b]thiophene (BDF-alt-TT) were designed and synthesized. Functional groups with different electron-withdrawing abilities such as carbonyl, ester, fluorine, sulfuryl and cyano were introduced to the thieno[3,4-b]thiophene unit to fin…
The poor solubility, poor biocompatibility and disposal issues make fluorescent quantum dots such as CdSe, CdS, ZnS, InP, InAs, etc. impractical for imaging tissues or intercellular structures. As calcium phosphate is the main inorganic component of human bone and teeth, hydroxyapatite (Ca10(PO4)6(OH)2, HAp) is highly…
In this paper, ligand free vertically aligned Cu2ZnSnS4 nanoplates were directly synthesized on a fluorine doped tin oxide substrate using a pulsed laser deposition (PLD) method, forming a nanoplate array. The array follows a two-step growth by first forming a Cu2ZnSnS4 thin film (∼100 nm), followed by vertical nanopl…
Bis(fluorenyl)benzothiadiazole-cored carbazole dendrimers show high thermal and electrochemical stability, and great potential as solution processed hole-transporting non-doped green emitters for OLEDs. A pure green device with CIE coordinates of (0.27, 0.62) and high luminance efficiencies (up to 10.01 cd A(-1)) is a…
An exploration of reactions of 3,3′,5,5′-tetra(1H-imidazol-1-yl)-1,1′-biphenyl (L) and 1,3,5-benzenetricarboxylic acid (H3BTC) with Co(II) salt has led to the formation of three new complexes with different framework structures, [Co2(L)(HBTC)2(μ2-H2O)(H2O)2]·3H2O (1), [Co3(L)2(BTC)2]·4H2O (2) and [Co2(L)(BTC)(μ2-OH)(H…
A fast and energy-saving anion exchange method for the synthesis of Ag3PO4 microcrystals with various shapes of sphere, rhombic dodecahedron, truncated tetragonal bipyramid microbox and self-assembled parallel quadrilateral prism has been described. The morphology of the Ag3PO4 crystals can be tuned by coordinating Ag…
In this paper we report a novel type, full lithium ion battery using a CuO–MCMB composite anode and a high voltage, LiNi0.5Mn1.5O4 cathode. We show that this battery operates for over 100 cycles at high rate and with excellent efficiency, performances that are rarely met in advanced lithium ion batteries. We assume th…
We employed graphene flakes as an air-cathode material for Li-O2 batteries and investigated their electrochemical properties in the dimethyl ether electrolyte. Graphene flakes were prepared by microwave-assisted reduction of graphene oxide, and their electrochemical properties were compared with those of Ketjen Black…
We report the synthesis, microstructure and Li ion conductivity of Li-stuffed garnet-type metal oxides, with nominal chemical formulae Li 7.06 La 3 Zr 1.94 Y 0.06 O 12 and Li 7.16 La 3 Zr 1.84 Y 0.16 O 12 . Powder X-ray diffraction (PXRD) shows the formation of cubic garnet-type structure at 950°C (12 h in air) with c…
Mesoporous anatase TiO2 spheres with tunable sizes ranging from 400 nm to 3 μm were synthesized using an original so-called "water-controlled solvothemal release process". In this method, the well-known esterification reaction between ethanol and acetic acid was creatively employed to generate water gradually during a…
Photocatalytic H2 production from water splitting using semiconductor photocatalysts has attracted much attention due to the increasing global energy crisis. In the past few decades, numerous photocatalysts have been proposed, however, it is still a challenge to develop highly active photocatalysts for water splitting…
Layered protonated titanates and corresponding anatase TiO2 shapes, specifically the hollow spheres, are the most important functional materials and have attracted much attention because of their superior performance. Here, a facile organic substrate (both as solvent or surfactant) free, low temperature aqueous soluti…
