The controlled ring-opening polymerisation (ROP) of an ATRP initiator-containing lactone, γ-BMPCL, and its copolymerisation with ε-caprolactone is reported. One resulting copolymer was successfully used as a substrate for surface initiated ATRP to produce surface-grafted poly(oligo(ethylene glycol) methacrylate) brush…
Pd-Mg-Pd thin films with variable thickness of Mg layers were prepared. Their optical and electrical changes in both gasochromic and chemochromic processes were compared to investigate the kinetics of Mg-based thin films at room temperature. Hydrogen absorption and desorption kinetics of Pd-Mg-Pd thin films were stron…
We developed a strategy for dual-stage delivery of fibroblast growth factor 1 (FGF-1) and bone morphogenetic protein 4 (BMP-4) within 3D biomimetic hydrogels to promote adipogenesis of human adipose-derived stromal cells.
During a dealloying process, reactive components in an alloy are selectively dissolved, leaving behind a bi-continuous porous structure composed of the remaining more noble constituents. This morphology has attracted attention in a variety of applications such as catalysis, actuation and sensing. Here, we show that si…
Antibacterial activity against <italic>Shigella dysenteriae</italic> , <italic>Staphylococcus aureus</italic> and <italic>Serratia marcescen</italic> was studied with <italic>S</italic> -BINOL based triazole dendrimers <bold>1</bold> , <bold>2</bold> and <bold>3</bold> with <italic>m</italic> -terphenyl surface units.…
A redox exchange mechanism between potassium perruthenate (KRuO4) and the functional groups of selected polymers is used here to induce RuO2 into and onto conductive polymer nanowires by simply soaking the polymer nanowire arrays in KRuO4 solution. Conductive polymer nanowire arrays of polypyrrole (PPY) and poly(3,4-e…
The ellestadite apatites Ca10[(SiO4)x(PO4)6-2x(SO4)x]Cl2 were studied by powder X-ray and neutron diffraction to establish baseline crystallographic data. These synthetic materials, unlike mineral specimens that are well equilibrated, show no Si/P/S ordering and conform to P63/m symmetry. Phosphate-rich ellestadites w…
Recent developments in the preparation of inorganic and inorganic–organic hybrid materials from inorganic layered compounds are reviewed. The focus is placed on three topics: preparation of new ion-exchangeable layered perovskites and a tungstic acid from Aurivillius phases via selective leaching of bismuth oxide shee…
, independent of the surface functionalization, and only minor differences in receptor expression on platelets (GP-IIb-IIIa, CD62, and CD63) relative to control samples were observed. Interestingly, the inter-subject variance of the clotting time is similar to the nanoparticle-induced effect in a single subject with a…
A new hybrid nanocomposite was designed by introducing decorated CNTs into a polymer for improving the sensitivity against polar vapours.
The influence of the basal length of Co(OH) <sub>2</sub> on supercapacitor performance was examined in detail by adding simple urea molecules during deposition. It was observed that the specific capacitance of Co(OH) <sub>2</sub> could be tuned from 700 to 1200 F g <sup>−1</sup> . This high specific capacitance was at…
Laboratory heats of an API X100 steel (Mn–Mo–Nb) with two levels of vanadium (0.004% and 0.063%) were melted and control rolled simulating a coiled plate production process. Extensive microstructural analyses were performed, including optical, EBSD and TEM. Texture analyses of the two alloys were also compared. Mechan…
Cu addition to the base alloy reduces the total amount of deleterious phases such as chromium nitride and sigma and chi phases. In particular, Cu addition to the base alloy results in pronounced suppression of the amount of sigma phase whereas it slightly facilitates the precipitation of chromium nitride and chi phase…
We report the optimal conversion of graphene oxide (GO) into white-lighting BCNO hybrid nanostructures by a one-step air oxidation process with the aid of boric acid and urea.
The aggregation equilibrium of a series of positively-charged water-soluble phthalocyanines (Pcs) was studied in aqueous solution by means of absorption and fluorescence techniques. The aggregation equilibrium in water depends on the bridging atoms between the pyridyl groups and the Pc core, and on the central metal o…
It remains as a great challenge to maintain the viability and functions of hepatocytes in vitro, and the construction of various scaffold materials and establishment of hepatocyte coculture systems are essential for the reconstruction of engineered liver devices. In our previous study, micropatterned electrospun fibro…
The ability to form self-organized thermotropic mesophases of amphiphilic cyclodextrins correlates well with their ability to establish an intermolecular H-bond network.
Smart stimuli-responsive superhydrophobic surfaces with reversibly switchable wettability have received considerable attention due to their various potential applications. We demonstrate here a new but versatile approach for preparing photoresponsive superhydrophobic surfaces. Fluorinated azobenzene derivatives or pol…
Self-assembly of amphiphiles is used as a tool for structuring carbonaceous materials in one and two dimensions. The dynamics of low-molecular weight amphiphiles are combined with the stability of their high-molecular weight analogues in order to control the self-assembly of these molecules. Two concepts for structuri…
