This work aims at understanding the formation and stability of a layered structure of brucite mineral [Mg(OH) 2 ] via density functional calculations. Because Mg−O−Mg bond formation from a hydrolyzed species of Mg(II) ion is a critical elemental step of mineralization, we studied the reaction mechanism of Mg−O−Mg link…

In this paper, we investigate the potential of ultrasonic energy in assisting the crystallization of dextrose monohydrate, which is primarily manufactured via slow cool batch, lasting 48 h (0.5 °C/h), seeded crystallization; this cooling curve is designed to optimize the crystal growth and give rise to relatively larg…

[structure: see text] A pyrrolic macrocycle, beta-tetrakis(trifluoromethyl)porphycene, is the first example of a fluorine-containing porphycene. Four electron-withdrawing CF(3) substituents provide a highly distorted structure and an attractive electron-deficient nature for the porphycene framework. From the electroch…

Inorganic mesoporous thin-films are important for applications such as membranes, sensors, low-dielectric-constant insulators (so-called low κ dielectrics), and fluidic devices. Over the past five years, several research groups have demonstrated the efficacy of using evaporation accompanying conventional coating opera…

The role of metal oxides on the thermal decomposition of poly(vinyl chloride) (PVC) and poly(vinyl acetate) (PVAC) and their blends was investigated by thermogravimetry (TGA). While the degradation of PVAC was mildly affected by the presence of metal oxides, the degradation of PVC was greatly influenced by metal oxide…

Gallium oxide nanowires were synthesized via chemical vapor deposition of gallium/gallium oxide mixture and oxygen. The diameter of the nanowires is 30−80 nm with an average value of 50 nm. They consist of single-crystalline monoclinic crystal. While the nanowires grown without catalyst exhibit a significant planar de…

We have created hybrid organic−inorganic nanoarchitectures by electrodepositing ultrathin (<10-nm-thick) polymer coatings onto nanostructured MnO 2 birnessite-type electrodes with surface areas in excess of 200 m 2 g -1 . By choosing a self-limited growth process, based on the electropolymerization of o -phenylenediam…

Structural, magnetic and ferromagnetic resonance characterization studies have been performed on lay-ered ferromagnetic-ferroelectric oxides that show strong magnetoelectric coupling. The samples contained thick films of ferrites or substituted lanthanum manganites for the ferromagnetic phase and lead zirconate titana…

Multiwalled carbon nanotubes (MWNTs) and ultrahigh molecular weight polyethylene (UHMWPE) composites were prepared by gelation/crystallization from solution. The dried composites of MWNTs−UHMWPE with 15 wt % of MWNTs would be elongated up to more than 100-fold (λ = 100). The electric conductivity was 10 -3 S/cm termed…

The electrospinning process was used successfully to fabricate nanofibers of poly(ethylene oxide) (PEO) in which multiwalled carbon nanotubes (MWCNT) are embedded. Initial dispersion of MWCNTs in water was achieved using amphiphiles, either as small molecules (sodium dodecyl sulfate, SDS) or as a high molecular weight…

Inelastic neutron scattering spectra were measured with a time-of-flight spectrometer on six disordered Cu-Au alloys at 300 K. The neutron-weighted phonon density of states was obtained from a conventional analysis of these spectra. Several methods were developed to account for this neutron weighting and obtain the ph…

Resonance Raman spectra and absolute cross sections have been measured for cresyl violet in aqueous solution and bound to the surface of SiO 2 colloidal nanoparticles. The absorption spectra of cresyl violet on SiO 2 have previously been interpreted to show formation of H-type dimers on the surface. The spectra of the…

We investigate the adsorption and diffusion of colloidal particles at an interface containing a one-dimensional potential well. It is observed how the adsorption kinetics onto the wall is altered with time, and one observes the formation of a particle chain. We find that the time it takes for a bead to penetrate into…

We probe the reversible thermal solidification of crowded solutions of colloidal star polymers in a marginal solvent upon addition of linear homopolymer chains consisting of the same monomers, and for two different linear polymer molecular weights we find that they have a dramatic impact on this phenomenon. If the lin…

First-principles calculations within density-functional theory are used to investigate zinc-blende-structured CrBi. Our calculation predicts ZB-type CrBi to be a true half-metallic ferromagnet with a magnetic moment of 3 μ B per formula. Its half-metallicity can be maintained over a relatively wide range of lattice co…
