Polymeric particle dispersions have numerous potential applications; currently one of the most relevant is their use as inks in electrophoretic displays. These colloidal particles are synthesized from the appropriate monomer using nonaqueous dispersion (NAD) polymerization in a nonpolar solvent, which requires a stabilizer to control particle size and morphology. We have previously reported the...

The interaction between deuterium-labeled Aerosol OT surfactant (AOT-d34) and sterically stabilized poly(methyl methacrylate) (PMMA) latex particles dispersed in nonpolar solvents has been studied using contrast-variation small-angle neutron scattering (CV-SANS). The electrophoretic mobilities (μ) of the latexes have been measured by phase-analysis light scattering, indicating that μ is negativ...

This data article provides: 1.An overview of tentatively identified long chain compounds in Dietzia sp. A14101 grown on simple and complex hydrocarbons;2.Preliminary Identification of pigments in bacterial material obtained from incubation with a hydrocarbon (dodecane, n-C12) as the only carbon and energy source;3.Some pictures to illustrate the cell surface charge test.

First-principles anharmonic vibrational calculations are carried out for the Raman spectrum of the C-H stretching bands in dodecane, and for the C-D bands in the deuterated molecule. The calculations use the Vibrational Self-Consistent Field (VSCF) algorithm. The results are compared with liquid-state experiments, after smoothing the isolated-molecule sharp-line computed spectra. Very good agre...

Sterically stabilized diblock copolymer nanoparticles with an intensity-average diameter of 25 nm are prepared in the form of a concentrated aqueous dispersion using polymerization-induced self-assembly (PISA). The addition of n-dodecane followed by high-shear homogenization produces n-dodecane-in-water Pickering macroemulsions of 22-46 μm diameter. If the nanoparticles are present in sufficien...

Micrometer-sized, monodisperse polystyrene (PS)/poly(styrene-co-sodium styrene sulfonate) (P(S-NaSS))/poly(n-butyl methacrylate) (Pn-BMA) composite particles having a ‘golf ball-like’ shape were prepared by seeded dispersion polymerization of n-butyl methacrylate with PS-core/P(S-NaSS)-shell seed particles with various shell thicknesses in the presence of dodecane droplets in a methanol/water (...

Examples from non-premixed boundary combustion representative of fire in microgravity environment are presented. A low forced flow 0.25 m/s is present, which typical air circulation speeds a spacecraft. The numerical simulations have been conducted to evaluate the modes heat transfer with an emphasis on discussion about effects various fuels chemical emissions such as soot, CO, CO2 and unburnt ...

The integration of the transmembrane (TM) proteins in the lipid bilayer depend on lipid-protein interactions. The few crystal structures known for multiple membrane spanning proteins suggest a basic form composed of bundles of a-helices that pack together. In the membrane helix-helix and helix-lipid interaction define the helix arrangement in the folded receptor. Thus, the lipid-protein interac...

In dual-fuel compression-ignition engines, replacing common fuels such as methane with renewable and widely available methanol is desirable. However, a fine-grained understanding of diesel/methanol ignition compared to diesel/methane lacking. Here, large-eddy simulation (LES) coupled finite rate chemistry utilized study diesel spray-assisted methanol. A surrogate fuel ( n-dodecane) spray inject...

The title compound, C(18)H(27)N(3)O, is a derivative of the anti-tuberculosis drug isoniazid (systematic name: pyridine-4-carbohydrazidei). The crystal structure consists of repeating C(4) chains along the b axis, formed by N-H⋯O hydrogen bonds with adjacent amide functional groups that are related by a b-glide plane. The cyclo-dodecyl ring has the same approximately 'square' conformation, as s...
