[Toxicological evaluation of the plasticizer PB-I].

Gig. Sanit. (4) , 50-2, (2000)

Microfluidic HPLC-Chip devices with integral channels containing methylstyrenic-based monolithic media.

J. Sep. Sci. 32(20) , 3379-87, (2009)

Polyimide HPLC-Chip devices containing poly(methylstyrene-bis-p-vinylphenyl)ethane (MS/BVPE) stationary phase within the device channels and with wall attachment were prepared by thermally initiated free radical polymerization. The microfluidic devices were c...

Identification of major water-soluble fluorescent components of some petrochemicals.

Mar. Pollut. Bull. 42(10) , 935-41, (2001)

The chemical identities of several organic compounds that dominate the ultraviolet (UV) fluorescence of water after exposure to gasoline, diesel fuel and crude oil are presented. A combination of high-performance liquid chromatography with UV-fluorescence det...

The NMR microimaging studies of the interplay of mass transport and chemical reaction in porous media.

Magn. Reson. Imaging 21(3-4) , 337-43, (2003)

PFG NMR is employed to perform a comparative study of the filtration of water and propane through model porous media. It is shown that the dispersion coefficients for water are dominated by the holdup effects even in a bed of nonporous glass beads. It is demo...

Novel charge-mosaic membranes.

Ann. N. Y. Acad. Sci. 984 , 245-55, (2003)

Novel charge-mosaic composite membranes composed of cation and anion permeable domains were prepared. Poly(4-methylstyrene-isoprene-styrene-isoprene-4-methylstyrene) pentablock copolymer (MsISIMs), poly(isoprene-4-methylstyrene) diblock copolymer (IMs), and p...

The ultrasensitivity of living polymers.

Phys. Rev. Lett. 90(11) , 118301, (2003)

Synthetic and biological living polymers are self-assembling chains whose chain length distributions (CLDs) are dynamic. We show these dynamics are ultrasensitive: Even a small perturbation (e.g., temperature jump) nonlinearly distorts the CLD, eliminating or...

Metabolism and disposition of alpha-methylstyrene in rats.

Drug Metab. Dispos. 29(2) , 166-71, (2001)

alpha-Methylstyrene (AMS) is a volatile hydrocarbon used primarily in the production of specialty polymers and resins. In the present study, the tissue distribution, metabolism, and excretion of [(14)C]AMS was investigated in male rats after i.v. administrati...

One color resonant two photon ionization spectroscopy of p-methylstyrene and theoretical calculation.

Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 66(2) , 371-6, (2007)

The band origin of the S1<--S0 transition of p-methylstyrene is determined to be 34,276 cm-1 by one color resonant two photon ionization (1C-R2PI) method, which is red shifted by 3811 cm-1 with respect to that of benzene. This indicates that the interaction o...

Aquatic toxicity evaluation of para-methylstyrene.

Ecotoxicol. Environ. Saf. 53(3) , 432-8, (2002)

The aquatic toxicity of para-methylstyrene was evaluated in acute toxicity studies using fathead minnows (Pimephales promelas), daphnids (Daphnia magna), and freshwater green algae (Selenastrum capricornutum). Static tests were performed in sealed containers ...

Functional MRI and NMR spectroscopy of an operating gas-liquid-solid catalytic reactor.

Magn. Reson. Imaging 23(2) , 221-5, (2005)

A dynamic in situ study of alpha-methylstyrene catalytic hydrogenation on a single catalyst pellet or in a granular bed is performed using 1H MRI and spatially resolved 1H NMR spectroscopy. Owing to reaction exothermicity, a reciprocating motion of the liquid...
