Here we report the synthesis of a new crystalline titanium phosphonate material (HTiP-7) having a self-assembled nanostructure and a mesoscopic void space without the aid of any surfactant or templating agent. The material has been synthesized hydrothermally through the reaction between benzene-1,3,5-triphosphonic aci…
A series of donor–acceptor molecules that incorporate N,N-dimethylaniline or carbazole as the common electron donor and 3-phenyl-5-isoxazolone as the electron acceptor moiety have been synthesized and their structural and optical properties and self-assembly behaviors were investigated. All these compounds showed the…
We propose a counter-intuitive mechanism of constructing an ultrathin broadband transparent device with two perfect blackbodies. By introducing hybridization of plasmon modes, resonant modes with different symmetries coexist in this system. A broadband transmission spectrum in the near infrared regime is achieved thro…
This paper reports on a simple and effective method for improving the electrochemical performance of silicon nanoparticle-core/carbon-shell (Si-core/C-shell) nanofibers. Instead of increasing the encapsulation amount of Si nanoparticles, additional conductive paths between the Si nanoparticles were formed by incorpora…
We demonstrate for the first time that a Pd nanolayer, which is in situ formed on the Ni foam via the galvanic exchange method, greatly improves the energy output, the round-trip efficiency and the cyclability of the aprotic Li-air battery in ambient or simulated air.
Broadband transparent electrodes, Ta2O5/Ag/WO3−x, are successfully designed to enhance light absorption and carrier transport properties in organic solar cells (OSCs) as an alternative to ITO/PEDOT:PSS. Employing the optical constant matching layer, zero reflection conditions could be achieved over a broad range of wa…
Nickel and cobalt are both known to stimulate the hypoxia-inducible factor-1 (HIF-1α), thus significantly improving blood vessel formation in tissue engineering applications. We have manufactured nickel and cobalt doped bioactive glasses to act as a controlled delivery mechanism of these ions. The resultant structural…
A photoinitiated RAFT process in fluoroalcohols (FAs) was successfully applied to the preparation of poly(vinyl acetate) and its hydrolyzed polymer, poly(vinyl alcohol), permitting the simultaneous control over the molecular weight (MW) and tacticity. The polymerization reaction displayed living polymerization charact…
Neurons receive thousands of synaptic inputs that are distributed in space and time. The systematic study of how neurons process these inputs requires a technique to stimulate multiple yet highly targeted points of interest along the neuron's dendritic tree. Three-dimensional multi-focal patterns produced via holograp…
Biomaterial encapsulation of islets has been proposed to improve the long-term success of islet transplantation by recreating a suitable microenvironment and enhancing cell-matrix interactions that affect cellular function. Protein polymer hydrogels previously showed promise as a biocompatible scaffold by maintaining…
The effect of hydrothermal treatment on the morphological and acid catalytic properties of titanate nanomaterials was examined. Anatase nanoparticles were converted into titanate nanotubes and layered titanate nanorods according to the heating temperature used during the hydrothermal treatment. Fourier transform infra…
We report a facile synthesis of superparamagnetic CoFe2O4 nanostructures with the assistance of an amino acid (lysine). Monodisperse CoFe2O4 nanospheres and nanoparticles were obtained by adjusting the synthesis parameters (such as the molar ratio of reactants and the solvent). The samples were characterized through s…
Control of the water splitting reaction in the context of natural photosynthesis is considered as a Holy Grail of chemistry, particularly with respect to artificial photosynthesis for a sustainable energy economy. The underlying objective is to build a solar fuel generator which is economically viable and environmenta…
Novel solution-processable thiol–ene gate dielectrics for use in organic thin-film transistors (OTFTs) have been designed and fabricated in this study. Incorporation of UV-sensitive functional groups in the thiol–ene system affords electrical and thermal stability to the gate dielectric layers by a simple photocuring…
1D and 2D homochiral nucleotides coordination polymers UMP/CMP-4,4′-bipy-M(II) (M = Co, Cu, Ni) 1–5 were designed, synthesized and analyzed by the single-crystal X-ray diffraction method. Axial chirality of 4,4′-bipy is captured and extended to a 1D infinite chain due to metal coordination and cooperation of a chiral…
Here we report the first membrane-free biofuel cell obtained using three-dimensional carbonaceous foam electrodes. We first developed a new synthetic pathway to produce a new carbonaceous foam electrode material bearing porosity both on the meso and macroporous scales. We proved that by increasing the porosity of our…
A new naked-eye chromogenic chemosensor based on 2-thiohydantoin shows high selectivity for fluoride ions and is used to develop a test paper for detection of fluoride ions in the solid state.
We herein report the synthesis and characterization of a new charged metal-organic framework, [Et2NH2][In(BPTC)] (InOF-2) (InOF = indium-organic framework; BPTC = biphenyl-3,3′,5,5′-tetracarboxylate), featuring an unc-type topology. Interestingly, InOF-2 undergoes a distinct porosity transition on going from a typical…
The free energies of exfoliation and dispersion for hexagonal boron nitride (h-BN) monolayers from a model h-BN bilayer calculated using adaptive bias force–molecular dynamics (ABF–MD) simulations advocate the use of ionic liquids (ILs) in the liquid exfoliation of h-BN to yield individually stabilized (isolated) nano…
The fabrication of glucose oxidase (GOx) enzyme electrodes with controlled alternate enzyme and graphene layers is described. GOx was first modified with pyrene functionalities in order to be self-assembled onto a graphene basal plane via non-covalent π-π stacking interaction. Fluorescence spectroscopy analysis reveal…
