Novel amphiphilic and photo-responsive ABC 3-miktoarm star terpolymers consisting of hydrophilic poly(ethylene glycol) monomethyl ether (MPEG), hydrophobic polystyrene (PS) and azobenzene-containing poly[6-(4-methoxy-azobenzene-4′-oxy) hexylmethacrylate] (PMMAZO) were synthesized by a combination of atom transfer radi…
We demonstrate the controlled doping of Sn into mesoporous TiO2 thin films, by a facile direct growth on conducting substrates (e.g. Ti) using the ligand-assisted evaporation-induced self-assembly method. The obtained Sn-doped mesoporous TiO2 thin films are polycrystalline with an anatase structure. The mesoporous TiO…
The preparation of anthracene-based low band gap conjugated polymers comprising 2,6-linked anthracene and dithienyl-benzo[c][1,2,5]thiadiazole or dibithiophenyl-benzo[c][1,2,5]thiadiazole alternate repeat units is presented. The photophysical, electrochemical and photovoltaic properties of the polymers in bulk heteroj…
The aim of this research study was to evaluate the influence of utilising natural polymers as a form of soil stabilization, in order to assess their potential for use in building applications. Mixtures were stabilized with a natural polymer (alginate) and reinforced with wool fibres in order to improve the overall com…
Vaterite particles containing aminopropyl-functionalized silsesquioxane (SiV) were prepared as osteogenic devices for bone regeneration. The SixV particles (x = 0, 2.6 and 4.9 wt%) were synthesized by reacting a slurry of calcium hydroxide with carbon dioxide gas in the presence of γ-aminopropyltriethoxysilane (APTES)…
For sub-10 nm thin metallic films, very little knowledge is available so far on how electron scattering at surface and grain boundaries reduces the thermal transport. This work reports on the first time characterization of the thermal and electrical conductivities of gold films of 6.4 nm average thickness. The electri…
Iron oxide nanoparticles were coated with the biocompatible, biodegradable, non-immunogenic polysaccharide inulin by introduction of carboxyl groups into the inulin structure and conjugation with amine groups on the surface of iron oxide nanoparticles grafted with 3-aminopropyltriethoxysilane. The resulting nanopartic…
The influence of Si/P ordering on Na(+) transport in the high conducting NASICON composition, Na3Zr2Si2PO12, is investigated using molecular dynamics simulation. The study demonstrates that the Na(+) conductivity in the system changes by more than an order of magnitude depending on the Si/P order in the structure. Thi…
A series of 3D homochiral manganese-lanthanide frameworks have been synthesized based on chiral camphoric acid. In the heterometallic features, D-camphoric acids are unprecedentedly embedded in three coordination modes.
The gas-phase oxidation of n-butane has been studied in an atmospheric jet-stirred reactor (JSR) at temperatures up to 950 K. For the first time, continuous wave cavity ring-down spectroscopy (cw-CRDS) in the near-infrared has been used, together with gas chromatography (GC), to analyze the products formed during its…
The solution-dissolved-state circular dichroism (CD) and the circularly polarized luminescence (CPL) of chiral binaphthyl fluorophores was controlled by both the axial chirality of the binaphthyl units as well as by the effect of neighboring binaphthyl units.
A BA-derived fluorescent pH sensor for use under strongly acidic conditions based on the ICT effect was realized to exhibit high stability, sensitivity and selectivity. This probe can be used to detect acidity within the pH range 0.5–2.5. The design strategy may help to develop probes for targets at high concentration…
New π-extended porphyrin dyes YD26-YD29 with long alkoxyl chains at the ortho positions of the meso-phenyls, and meta di-tert-butylphenyl-substituted porphyrins YD12-CN, and YD13-CN were synthesized for dye-sensitized solar cells, and their optical, electrochemical and photovoltaic properties were investigated and com…
By using 4-(pyrimidin-5-yl) benzoic acid (4-PmBC) as a ligand, a porous metal-organic framework based on unique octa-nuclear copper clusters was constructed, which exhibited highly selective CO2 uptake over N2 and CH4.
A facile strategy was initiated to fabricate large-scale uniform brookite TiO2 nanospindles preferentially grown along the [001] direction, which were highly thermally stable and exhibited superior electrical conductivity, about two orders of magnitude higher than those of anatase and rutile counterparts.
The advantages of one-dimensional nanostructures, such as excellent charge separation and charge transport, low charge carrier recombination losses and so on, render them the photocatalysts of choice for many applications that exploit solar energy. In this work, based on very recently synthesized ultrathin anatase TiO…
Human adult mesenchymal stem cells (MSC) can be readily harvested from bone marrow through aspiration. MSC are involved in tissue regeneration and repair, particularly in wound healing. Due to their high self-renewal capacity and excellent differentiation potential in vitro, MSC are ideally suited for regenerative med…
Amino acid ionic liquids provide suitable media for lyotropic liquid-crystalline systems whose self-organisation behaviour is tuneable by the selection of amino acid anions.
A facile approach was developed to assemble DNA-functionalized gold nanoparticles on the electrospun nanofibers. This novel nanocomposite was successfully applied to constructing a highly sensitive and selective fluorescent sensor for nucleic acids.
Because of their outstanding molecular optoelectronic properties, perylene diimides (PDIs) are promising alternatives to the commonly used PCBM. However, the overly strong aggregation ability, poor solution-processability and compatibility of PDIs severely limit their photovoltaic applications. We turned to borrowing…
