Cerium dioxide nanoparticles have been proposed for an increasing number of applications in biomedicine, cosmetic, as polishing materials and also as byproducts from automotive fuel additives. The aim of this study was to examine the potential in vitro cyto- and genotoxicity of nano-sized CeO2 (7 nm) on human dermal f…
Multiple facet supported alumina nanowires are produced very efficiently in a very short time via high field anodization; upon modification with perfluorosilane, the surface becomes super-repellent towards a broad range of liquids, which includes (salted) water, water emulsion, common organic liquids like glycerol and…
We used a suite of transmission electron microscopy (TEM) and associated electron spectroscopy methods to examine the local structure and changes in the electronic structure of positive electrode material. We found a scattered rock-salt phase near grain surfaces and grain boundaries, where turned to , deduced from rel…
This paper is an overview of our recent understanding of the effects of surfactant type and bubble surface mobility on foam rheological properties. The focus is on the viscous friction between bubbles in steadily sheared foams, as well as between bubbles and confining solid wall. Large set of experimental results is r…
A facile layer-by-layer deposition process is developed to fabricate highly-transparent superhydrophobic coatings, which comprise the underlying antireflective nanoporous silica layer and the top transparent superhydrophobic SiO(2) nanoparticle layer.
Enhanced upconversion emission of NaYF(4):Yb,Er nanocrystals with Ag nanowires was observed; the enhancement factor of red emission is larger than that of green emission, and it can be further increased with Ag islands composed of larger Ag particles.
We unveil a new luminescent assay using 11-mercaptoundecanoic acid-bound Au nanodots (11-MUA-Au NDs) for the highly selective and sensitive detection of hydrogen peroxide and glucose, based on luminescence quenching.
Fibres usually experience tensile loads whether they are used for apparel or technical structures. Their form, which is long and fine, makes them some of the strongest materials available as well as very flexible. This book provides a concise and authoritative overview of tensile behaviour of a wide range of both natu…
Supramolecular nanostructures covered with bioactive functional molecules have been actively explored as promising materials in the field of biotechnology. Recent advances in nano-sized chemistry have made it possible to fabricate various kinds of nanostructures with tailor-made nanostructural properties. This, combin…
In this feature article, the applications of layered nanomaterials as green materials are demonstrated along with their structures and properties. Due to the unique 2-dimensional structures and biocompatibility, various eco- and bio-friendly materials can be hybridized with layered nanoparticles such as layered double…
This paper presents a modelling study of the electrochemical hydrogen oxidation reaction at nickel/yttria-stabilized zirconia ͑Ni/YSZ͒ patterned anodes.An elementary kinetic reaction-diffusion model accounts for coupled heterogeneous chemistry and transport on the Ni and YSZ surfaces.Charge transfer is modeled as a sp…
Regenerated cellulose microspheres (RCS) were successfully prepared by using the sol-gel transition (SGT) method from cellulose drops in 7 wt% NaOH/12 wt% urea aqueous solution precooled to −12 °C. Subsequently, novel magnetic Fe3O4/cellulose microspheres (MRCS) were fabricated by in situ synthesis of Fe3O4nanoparticl…
Prawn shells, an abundant marine chitin (poly-β(1→4)-N-acetyl-D-glucosamine) biomass source and high volume food waste, have successfully been converted into nitrogen doped carbon (>5% N) in a simple three step sustainable manner to yield a highly textured, high surface area (SBET > 300 m2g−1) and high pore volume (Vp…
Metal nanoparticle-polymer composites are versatile materials which not only combine the unique characteristics of the components, but also manifest mutualistic effects between the two. Embedding inside polymer thin films facilitates immobilization and organization of the metal nanoparticles and tuning of their electr…
A new heteroleptic ethyl-zinc complex stabilized by a chelating bis(morpholinomethyl)phenoxy ligand has been synthesised and shown to be a highly potent initiator for the immortal ring-opening polymerisation (ROP) of lactide and beta-butyrolactone, being able to convert up to 50,000 equiv. of monomer in the presence o…
Highly dense arrays of ordered and aligned nanorods of polyaniline with 10 nm diameter on transparent ITO substrate have been successfully fabricated using supramolecular assemblies of block copolymer as scaffold material; the ordered arrays of polyaniline nanorods so fabricated were found to exhibit excellent electro…
In an attempt to elucidate the remarkable stability of foams generated from dispersions of partially hydrophobic nanoparticles (fumed silica), we present investigations into the static and dilational properties of the gas–liquid interfaces of such dispersions. By relating the dynamic surface tension γ(t) and the dilat…
Efficient chiroptical molecular redox switches have been engineered that display multiple stable optically active forms, chemically reversible redox processes, and highly sensitive chiroptical responses. Systems that have been studied in this context include electro-active organic polymers, redox-active coordination c…
Disease-causing microbes that have become resistant to drug therapy are an increasing public health problem. Therefore there is an urgent need to develop new bactericides. Silver nanoparticles are the metal of choice as they hold the promise to kill microbes effectively. Silver nanoparticles take advantages of the oli…
Polydopamine (Pdop) nano/microcapsules are readily produced through the oxidative polymerization of dopamine and the spontaneous deposition of Pdop on the template surface, followed by the removal of the template. The Pdop capsules are very robust and stable under different pH. Most importantly, they exhibit outstandi…
