Reported herein are the synthesis, structural, magnetic and Mössbauer spectroscopic characterisation of a dinuclear Fe(II) triple helicate complex [Fe(2)(L)(3)](ClO(4))(4).xH(2)O (x = 1-4), 1(H(2)O), where L is a bis-bidentate imidazolimine ligand. Low temperature structural analysis (150 K) and Mössbauer spectroscopy…
Although self-assembly (SA) in two dimensions (2D) is highly developed (especially using surfaces as a templates), SA in three dimensions (3D) has been more difficult. This paper describes a strategy for SA in 3D of diamagnetic plastic objects (mm- to cm-sized in this work, but in principle in sizes from ∼10 μm to m)…
Nano-oncology, the application of Nanomedicine to cancer diagnosis and treatment, has the potential to transform clinical oncology by enhancing the efficacy of cancer chemotherapy for a wide spectrum of invasive cancers. It achieves this by enabling novel drug delivery systems which target the tumour site with several…
This study examined how the strain rate affects the room-temperature tensile behavior of hydrogen-charged 316L stainless steels. A high-temperature homogenization treatment was applied to the specimens after hydrogen charging and copper electroplating to remove the hydrogen concentration gradient. A softening phenomen…
Silver nanoparticles are commonly used in a variety of commercial and medical products. Here we investigate the effects of standard sterilization methods, including heat/steam (autoclave) and gamma-irradiation on the structural integrity and biocompatibility of citrate-stabilized silver nanoparticles with nominal size…
The chemistry of molecular assemblies involves weak yet complex non-covalent interactions, and the molecular organization of the π-conjugated material is crucial in determining the performance of an organic electronic device. Herein we demonstrate a bioinspired design strategy to tune the self-assembly of naphthalened…
In this highlight, attempts have been made to focus on the effect of physico-chemical properties of nanoparticles, such as chemical composition, solubility, particle size, and specific surface area, on the toxicity. Among various inorganic particles, layered double hydroxides on nano scales were especially studied in…
Well-defined porous Co3O4 microcubes have been synthesized by a simple one-pot solvothermal method combined with subsequent calcination. The formation mechanism of the cube-like precursor was proposed based on the anisotropic intrinsic structure of CoCO3. Importantly, after thermal treatment, the cube-like morphology…
Plastic wastes have a potential to play a significant role in the reduction of iron oxides by supplying reducing gases, e.g., H2 and CO, through pyrolysis. However, they are difficult to use as reducing agents because the thermal degradation temperatures of plastics are significantly lower than the reduction temperatu…
Silaffins are highly charged proteins which are one of the major contributing compounds that are thought to be responsible for the formation of the hierarchically structured silica-based cell walls of diatoms. Here we describe the synthesis of an oligo-propyleneamine substituted lysine derivative and its incorporation…
A novel iron(II) mononuclear spin transition complex [FeL(py)(2)] displays an abrupt spin transition around 225 K accompanied by a very wide thermal hysteresis loop (∼50 K) that spreads out over 100 K. Crystal structure analysis in both low-spin and high-spin states reveals a lipid layer-like arrangement of the comple…
The syntheses, crystal structures and magnetic studies are reported for a series of Ln(4) clusters formulated as Ln(4)(μ(3)-OH)(2)(php)(2)(OAc)(6)(H(2)O)(2)]·4MeOH·nH(2)O (Ln = Gd (1), Tb (2), Dy (3) (n = 2) and Ho (4) (n = 0); H(2)php = 2,6-(picolinoylhydrazone)pyridine). The overall metal core of each cluster is com…
Self-assembly in aqueous solution has been investigated for two Fmoc [Fmoc = N-(fluorenyl)-9-methoxycarbonyl] tetrapeptides comprising the RGDS cell adhesion motif from fibronectin or the scrambled sequence GRDS. The hydrophobic Fmoc unit confers amphiphilicity on the molecules, and introduces aromatic stacking intera…
A facile method utilizing superhydrophilic materials to manipulate oil droplets freely in water is provided in this study. Due to the hydrophilic property and hierarchical structures of frosted glass plates, water was trapped in the interstices of glass microstructures. Trapped water served as supporting points to eff…
A new mechanism for enhancing the visible light absorption of a homogeneous polyoxovanadate system is described. The photoactive pentanuclear {V(5)} isopolyoxovanadate cluster is formed in situ by a thermally-induced condensation reaction starting from a tetranuclear {V(4)} precursor. Upon irradiation with visible lig…
Re-dispersible Tb(3+) doped LaPO(4) nanorods have been prepared using ethylene glycol (EG) as a capping agent as well as reaction medium at a relatively low temperature of 150 °C. The X-ray diffraction study reveals that all the doped samples are well crystalline with a monoclinic structure of the LaPO(4) phase. The l…
SrSi 2 O 2 N 2 : Eu 2+ green phosphors are prepared using a convenient solid-state reaction with Sr 2 SiO 4 : Eu 2+ as the precursor. The activation energy of crystallization, electron-phonon coupling, and thermal quenching behavior are investigated using differential thermal analysis (DTA) spectra and photoluminescen…
A dispersible graphene/gold nanoclusters hybrid in aqueous solution was fabricated in situ based on the bilayer graphene template, and its electrogenerated chemiluminescence (ECL) behavior was studied.
A terbium(III) complex gives off strong luminescence upon reacting with human serum albumin in aqueous solution, which can be used to detect the presence and structural modifications of this protein.
Galvanic deposition of Au onto a thin-sheet sinter-locked 8 μm Ni-fiber delivers a high-performance Au/Ni-fiber catalyst for alcohol oxidation, due to the unique combination of excellent heat conductivity, remarkable low-temperature activity, and good stability/regenerability. The special NiO@Au ensembles formed durin…
