Metal-induced lateral crystallization (MILC) of amorphous Ge has been investigated to realize low temperature formation of poly-Ge films on insulating substrates. From a comparative study of MILC with various catalysis metals (Ni, Co, Pd, and Cu), it was found that Cu enhanced both nucleation and subsequent nucleus gr…
A novel photocatalytic hydrogen evolution system was constructed by using well-dispersed layered double hydroxide (LDH) to immobilize the photosensitizer (rose bengal, RB) and photocatalyst (Pt). The produced amount of H(2) from such a self-assembled RB-LDH-Pt system is a few times more than that from the Free system…
A novel kind of rattle-type magnetic mesoporous sphere with a hollow magnetite core and perpendicularly aligned mesoporous carbon shell (RTMMCS) has been successfully fabricated. In addition, the RTMMCS demonstrates strong surface affinity toward contaminants, which contributes to the convenient, efficient, and fast r…
A wide selection of insoluble nanoparticulate metal salts was screened for avid binding of [(18)F]-fluoride. Hydroxyapatite and aluminium hydroxide nanoparticles showed particularly avid and stable binding of [(18)F]-fluoride in various biological media. The in vivo behaviour of the [(18)F]-labelled hydroxyapatite and…
The reaction of the flexible tris-phosphonate precursor benzene-1,3,5-tris(methylenephosphonic acid) (H6btmp) with CuCl2·2H2O in H2O under hydrothermal conditions afforded the complex [Cu3(btmp)(H2O)3.6]·H2O (1·H2O). A similar reaction between 2,4,6-trimethylbenzene-1,3,5-tris(methylenephosphonic acid) (Me3-H6btmp) an…
A direct photopatternable organosiloxane-based organic–inorganic hybrid gate dielectric was synthesized. The sol–gel derived hybrid dielectric could be cured at a temperature sufficiently low enough to apply to temperature-sensitive polymeric substrates, whilst maintaining good electrical properties. The addition of h…
The search for photosensitive alkoxyamines represents a huge challenge. The key parameters governing the cleavage process remain unknown. The dissociation process of light sensitive alkoxyamines is studied as a function of their chemical structures. The photochemical properties of 6 selected compounds are investigated…
In this work, we report for the first time a simple two-step route to fabricate a novel porous metal oxide film composed of polycrystalline nanowires with ultra-small nanoparticles, good interconnectivity between nanoparticles, and a high density of ultra-fine nanopores. The as-prepared metal oxide films combine the a…
A Sn–C–Ni composite thin film has been prepared by electron beam evaporation using a TiNi alloy as a reaction medium. The thin film with a multi-scale structure is composed of lots of micro-sized core/shell particles. The cores are Sn single crystals and the shells are amorphous carbon with nano-sized Sn and Ni partic…
The introduction of solvent-free nanofluids composed of suitably surface functionalized nanoparticles (nanosilica for example) has led to some interesting new materials. Here we show that the process of surface functionalizing with both nanofluid-inducing surface groups and with reactive (acrylate) surface groups prod…
Chemical-looping combustion (CLC) is a combustion concept with inherent separation of CO2. The process uses a solid oxygen carrier, which consists of metal oxide, to transfer the oxygen from air to fuel. This paper presents findings from batch tests performed in a 10 kWth CLC pilot for solid fuels. The pilot, which is…
Herein using classic DNA binding Ru polypyridine complex and graphene oxide, we developed a label-free and simple method for fluorescence recognition of complementary double-stranded DNA and aptamer-based potassium ions detection processes.
It has been shown that the application of self-assembled monolayers (SAMs) to semiconductors or metals may enhance the efficiency of optoelectronic devices by changing the surface properties and tuning the work functions at their interfaces. In this work, binary SAMs with various ratios of 3-aminopropyltrimethoxysilan…
Current in vitro models have provided insights into collagen mineralization. However, the role of the collagen fibrillar framework in the formation of carbonated hydroxylapatite (CHA) has not been clarified due to difficulties in processing biomimetic fibrillar collagen gels with tailored properties. In this work, rec…
A simple strategy based on unmodified AuNPs and specific Zn(2+) binding peptide is exploited here as a new label-free mechanism for the rapid colorimetric Zn(2+) assay.
Nrat1 is a plasma membrane-localized aluminum transporter recently identified in rice, which is a member of Nramp family. Here, we further characterized this transporter in terms of transport substrate specificity. Heterologous assay in yeast showed that Al transport activity by Nrat1 was unaffected by the presence of…
The first synthesis of a carbohydrate molecule covalently bound to a rigid lanthanide binding tag is reported. This derivative has been designed as a new tool to provide long-range restraints for structural elucidation and molecular recognition studies of carbohydrates, thus extending the methodology already developed…
Three novel lanthanide-organic frameworks, [Ln3(μ3–OH)2L2(HCO2)3(H2O)2]·H2O (Ln = Eu (1), Gd (2), Dy (3); H2L = 3,3′-dimethoxy-4,4′-biphenyldicarboxylic acid), have been prepared by the solvothermal reaction of Ln(NO3)3·6H2O and H2L in DMF/H2O mixed solvent. Crystallographic data show that 1–3 are isomorphous and crys…
WO3 mesoporous films were prepared using a sol–gel method to serve as the photoanode for water cleavage in a 1 M HClO4 solution with Pt as the counter electrode. Post-treatment of the as-synthesized WO3 film with methanol and ethanol vapors, especially with methanol, improves the photocurrent during photoelectrolysis…
A facile and effective treatment method for controlling the morphology of bulk heterojunction (BHJ) structured polymer-based solar cells (PSCs) using a gas-assisted spray (g-spray) technique was demonstrated. High-efficiency BHJ-PSCs were fabricated using a g-spray method that can be adapted to large-scale high-throug…
