We have succeeded in synthesizing a single-phase (binderless) ultra-hard nano-polycrystalline diamond (NPD) by direct conversion sintering from graphite under ultra-high pressure and high temperature. The hardness of NPD is considerably high, far surpassing that of single-crystal diamonds even at high temperature. In…
A bis-silylated diethyl 2,5-bis[N,N-(3-triethoxysilyl)propylurea]terephthalate precursor (5) was synthesized from a terephthalate derivative (3) and successfully used to prepare highly fluorescent organosilicas by hydrolytic self-condensation (DPM1) and co-condensation (DPM2) with tetraethoxysilane. The dyes 3 and 5 p…
Ultrathin hybrid films of graphene oxide (GO) and monolayer titania (TO) were assembled by layer-by-layer and drop-casting methods. The photo-induced wettability modulation of the hybrid films with different configurations was systematically studied. Due to the photocatalytic reduction of GO by TO, GO sheets in the hy…
The interaction of two luminescent metallopolymers; [Ru(bpy)(2)(PVP)(10)](2+) and [Ru(bpy)(2)(CAIP)co-poly(7)](+), where bpy is 2,2'-bipyridyl, PVP is polyvinylpyridine, and (CAIP)co-poly(7) is poly(styrene(6)-co-p-(aminomethyl)styrene) amide linked to 2-(4-carboxyphenyl)imidazo[4,5-f] [1,10]phenanthroline, with the D…
This paper is a continuation of a series of publications dealing with the protection of metals by volatile corrosion inhibitors (VCIs).It presents a review on the propagation of VCI vapors, VCI distribution in the volume being protected, and specifics of vapor-phase protection of isolated systems and systems interacti…
Abstract—The design, fabrication and measurement of a reconfigurable fishnet metamaterial based on a new method of tuning by changing unit cell geometry is reported. Retractable elements are added to the unit cell utilizing pneumatically actuated switching. It is shown that the pneumatic actuation approach can unite a…
Anodic oxidation of a pure Al plate was carried out in aqueous solutions containing sulfuric acid (H2SO4), oxalic acid (H2C2O4) and a percarboxylic acid-based additive at temperatures between 273 and 293 K for 0.6 to 9 ks under a constant current density of 300 A·m−2 (3 A·dm−2). The microstructures and the mechanical…
To develop methods for quantifying the effects of the microstructural variations of woven ceramic matrix composites on the effective properties and response of the material, a research program has been undertaken which is described in this paper. In order to characterize and quantify the variations in the microstructu…
We demonstrate a general approach for growing selectively semiconductor nanocrystals onto the edges of elongated Cd–chalcogenide nanostructures. Our approach utilizes the thermal decomposition of metal bisdiethyldithiocarbamate precursors to achieve selective growth onto cadmium chalcogenide nanostructures.
Personalized cancer therapies drive the need for devices that rapidly and accurately segregate cancer cells from solid tumors. One potential sorting strategy is to segregate populations of cells based on their relative strength of adhesion. To investigate the effect of surface hydrophilicity and cell phenotype on adhe…
Monodispersed Ce3+-doped Y3Al5O12 (YAG:Ce3+) nanospheres were synthesized through forced hydrolysis using a urea method, followed by thermal calcination processes, and their luminescence properties were examined. The crystallization of the YAG:Ce3+ phase and morphological evolutions after subsequent heat treatment wer…
We have detected the existence of different geometrical isomers of high-spin Ni9W6 clusters with symmetrical bidentate blocking ligands, and have proposed the classifications of the isomers. A series of pentadecanuclear body centred full-capped octahedral clusters with symmetrical diimine blocking ligands of the gener…
Six supramolecular compounds constructed by main group and transition metals, polyoxotungstates (SiW(12)O(40)(4-)) and trans-N,N,N',N'-1,2-cyclohexanediaminotetraacetic acid (H(4)CyDTA), (NH(4))(3)[Ni(4)Na(H(2)O)(10)(CyDTA)(2)][SiW(12)O(40)]·10H(2)O (1) (NH(4))(2)[Cu(3)Na(2)(HCyDTA)(2)(H(2)O)(13)][SiW(12)O(40)]·5H(2)O…
The dipolar and octupolar contributions of the second order nonlinear optical properties of [(4'-(C(6)H(4)-p-D)-2,2':6',2''-terpyridine)-Ru-(4'-(C(6)H(4)-p-A)-2,2':6',2''-terpyridine)]Y(2) heteroleptic complexes (D and A are donor and acceptor groups, respectively), and related free terpyridines and homoleptic complex…
We study the dynamics of a foam lamella in a confined channel under the influence of a pushing–pulling pressure. Using optical interferometry we evidence an instantaneous swelling described by a velocity power law for different compositions of the foaming solutions. Based on theoretical considerations we show that the…
The cell responses to biopolymer surface at the early adhesion stages can be critical for cell survival. The purpose of this research was to assess formation of hyaluronic acid (HA) biopolymer surface, the fibroblasts were used as an experimental model to evaluate the responses of cellular proteins induced by biopolym…
Ultrasmall quantum dots (< 2 nm) have been synthesised by redirecting crystal growth to dissolution during the synthetic process. The redirection is carried out with a controlled quenching–isothermal annealing process, where quantum dots are first grown and then quenched to a lower temperature, followed by thermodynam…
Poly[2-(methacryloyloxy)ethylphosphorylcholine]-coated SPIONs were prepared through ATRP and amidation coupling reactions. The coated SPIONs exhibited high stability and re-dispersability in phosphate buffered saline and uptake in a stem cell line, with high T(2) relaxivity.
A model for the adsorption of colloidal particles on a planar surface is analyzed by using a thermodynamic chemical equilibrium model and Monte Carlo simulations. Central to this investigation are that (i) particles and surface are considered to be of the same material and (ii) the particle–surface and particle–partic…
A white-amethyst photochromic material, Ba 10 (PO 4 ) 6 ClF:Eu 2+ ,Gd 3+ , was synthesized. This material is sensitive to electromagnetic waves from ultraviolet (UV) to X-ray. The material changes its color from white to amethyst under UV or X-ray irradiation. The photo-colored sample can be bleached by green light ir…
