Six new Cd(II) coordination polymers, namely, {[Cd2(CH3O-ip)2(1,3-btp)2(H2O)2]·7H2O}n (1), {[Cd(CH3O-ip)(1,3-bip)]·H2O}n (2), {[Cd(CH3O-ip)(1,4-btb)0.5(H2O)]·2H2O}n (3), {[Cd(CH3-ip)(1,3-btp)(H2O)]·H2O}n (4), {[Cd(CH3-ip)(1,6-bth)(H2O)]·H2O}n (5), {[Cd(CH3-ip)(1,4-btb)0.5(H2O)]·H2O}n (6) (CH3O–H2ip = 5-methoxyisophtha…
We report the rational synthesis of carbon and nitrogen co-treated ZnO (denoted as CN/ZnO) nanorod arrays and their implementation in photoelectrochemical hydrogen evolution. The CN/ZnO nanorods exhibit an enhanced photocurrent and stability owing to the improved light-harvesting ability, the reduced surface defects a…
TiO2 and TiO2-Ag composites films were prepared by sol–gel method and coated on glass fibre roving. The surface morphology and properties of synthesized composites films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDS), Fourier transform infr…
The synthesis of cyclodextrin-centred star polymers via thiol-ene addition of per-6-thio-β-cyclodextrin (CD-(SH)(7)) with vinyl terminated polymers is described. The obtained thiol-ene product was employed as an initiator for ring opening polymerization (ROP) of ε-caprolactone (ε-CL).
The analyte-induced formation of exciton trapping leads to the decrease of cathode photocurrent of mercapto-capped CdTe quantum dots (QDs), which produces a sensitive cathode photoelectrochemical method for selective sensing of trace Cu(2+) as the analyte with a linear range from 0.06 to 100 μM.
A synthetically versatile strategy has been employed for luminescence colour tuning in a new series of bipolar carbazole–2,5-diaryl-1,3,4-oxadiazole hybrid molecules 1–7. Their syntheses, solution absorption and emission properties and cyclic voltammetric data are reported. Calculations using DFT (density functional t…
We explore the use of graphene modified electrodes towards the electroanalytical sensing of various analytes, namely dopamine hydrochloride, uric acid, acetaminophen and p-benzoquinone via cyclic voltammetry. In line with literature methodologies and to investigate the full-implications of employing graphene in this e…
A new family of Al-based MOFs denoted as CAU-3 (CAU = Christian-Albrechts-Universität) was discovered in the solvothermal system Al(3+)/aryldicarboxylic acid/NaOH/methanol by applying high-throughput-methods. The three compounds reported in this article [Al(2)(OCH(3))(4)BDC], [Al(2)(OCH(3))(4)BDC-NH(2)] and[Al(2)(OCH(…
Carbon-modified BiVO(4) microtubes embedded with Ag nanoparticles (BVO@C/Ag MTs) were obtained by a two-step fabrication route. First, the BiVO(4)@carbon core-shell microtubes (BVO@C MTs) were fabricated by using BiVO(4) microtubes (BiVO(4) MTs) as a hard-template through a hydrothermal approach. Next, small Ag nanopa…
We present a facile synthetic route toward binder-free, highly-dispersed Ge nanoparticles in carbon matrices using one-step pyrolysis of self-assembled Ge-polymer hybrids. 3-Dimensionally arranged Ge-carbon exhibits remarkably enhanced cycling properties and rate capability compared with carbon sheathed Ge lacking org…
We present a simple method for fabricating hierarchical polymeric nanohairs using a multi-branched anodic aluminum oxide (AAO) template prepared by two-step anodization and barrier layer thinning processes. Combined with nanohair yielding of a polymeric material during peeling-off from the hydrophobically modified AAO…
Nanosized gold particles were functionalised with two types of paramagnetic surface tags, one having a nitroxide radical and the other one carrying a DTPA complex loaded with Gd(3+). Selective measurements of nitroxide-nitroxide, Gd(3+)-nitroxide and Gd(3+)-Gd(3+) distances were performed on this system and informatio…
The synthesis of high quality ZnO nanowire (NW) arrays on a range of conventional conductive substrates has important applications in LEDs, nanogenerators and piezotronics. In this paper, using ammonium hydroxide as the reactant, together with zinc nitrate hexahydrate, ZnO NW arrays have been grown on various patterne…
Using Stille and Suzuki polymerization reactions we incorporate thienoisoindigo (TII) as an acceptor co-monomer into a series of alternating π-conjugated copolymers with combinations of benzene, thiophene and carbazole as donor co-monomers. By changing the nature and length of the donor segments, the optical band gap…
Two novel D-π-A-π-D structured small molecules composed of benzothiadiazole and triphenylamine were designed and synthesized. with cyano on the π-bridge exhibited a deep HOMO energy level, resulting in an impressive V(OC) of up to 1.04 V with a PCE of 3.85%, while non-cyano substituted yielded a V(OC) of 0.94 V and a…
Small amounts of SO3H-functionalised room temperature synthesized ionic liquids efficiently dehydrate aqueous xylose to furfural under microwave heating at mild reaction conditions. The RT-ionic liquid catalysts were also found to be effective catalysts for the two step one-pot simultaneous hydrolysis and dehydration…
Anatase TiO2 hierarchical nanostructural microspheres with tunable pore size, pore volume, and specific surface area were prepared by a facile two-step method of electrospray and hydrothermal treatment. Compared to the calcination, the hydrothermal treatment can transfer the electrosprayed TiO2 microspheres to porous…
A high solar-to-electricity conversion efficiency of 7.22% was achieved with a short circuit current (J(sc)) of 15.30 mA cm(-2), an open circuit voltage (V(oc)) of 669 mV and a fill factor (FF) of 0.71 for the 2Flu-ZnP-CN-COOH dye with a multi-functional co-adsorbent, under 100 mW cm(-2) AM 1.5 G simulated light.
A novel α-Fe2O3/graphene composite is prepared by a simple in situ wet chemistry approach. The α-Fe2O3 particles with diameter around 130 nm are homogeneously anchored on graphene nanosheets to form a 3D quasi-laminated architecture. Such a well-organized flexible structure can offer sufficient void space to facilitat…
Highly stable and high performance solution-processed amorphous oxide semiconductor thin film transistors (TFTs) were produced using a Li and Zr co-doped ZnO-based aqueous solution. Li and Zr co-doping at the appropriate amounts enhanced the oxide film quality in terms of enhanced oxygen bonding and reduced defect sit…
