Construction of crystalline homo/heteroaggregation at micro/nanometer level from organic ?-conjugated systems is great importance because the controllable morphologies (i.e., size, shape, and dimension) could provide diverse optoelectronic properties for different applications in electrooptical devices. In this review, we summarize our recent progress self-assembly micro/nanostructures molecule...

• Interfacial energies calculated for calcite with water and ACC. Predictions made dissolution+re-precipitation vs solid state transformation. Discussion of use in classical nucleation theory. The interfaces water, dehydrated hydrated amorphous calcium carbonate are studied molecular dynamics simulations. interfacial demonstrate that the interface is most stable when contact or low concentratio...

We have designed and synthesized a new symmetrical porphyrins 3a-d and their nanoparticles based on extended π-conjugation concept. The new sensitizers were fully characterized by CHN analysis, UV-Vis., H-NMR, TEM and Mass spectroscopy. The new sensitizers and their nanoparticles were evaluated as antitumor activity against HepG2, WI-38, VERO and MCF-7 cell lines. It was found that porphyrin na...

Organic semiconductor nanoparticles provide a potentially scalable approach for photovoltaics that can be processed from aqueous media. Particles of poly(3-hexylthiophene) (P3HT):phenyl-C61-butyric acid methyl ester (PCBM) were prepared using two techniques; those produced by a mini-emulsion method contained greater amounts of crystalline P3HT domains with charge generation resembling phase-sep...

The oxidation resistance of TiC/Ni composites is crucial for its application in high-temperature environment. in-situ are fabricated by reactive sintering method, and the influence TiC particle size on composite studied. increases from 1.54 μm to 2.40 as holding time prolongs 2 h 6 h, due dissolution-reprecipitation mechanism. kinetics with different oxidized at 800 °C 100 obeys parabolic kinet...

Abstract Garnet commonly accommodates high contents of Mn + Y heavy rare earth elements (HREE) that follow Rayleigh fractionation during garnet early growth, with the exception overstepping nucleation (late crystallization owing to reaction overstepping). Because this, as porphyroblasts form mostly in equilibrium surrounding matrix, concentration these continuously decreases towards porphyrobla...
