Rate constants for elementary gas-phase reactions were first measured reliably following the development of pulsed photolysis and flow methods in the 1960's. These techniques have continued to be employed as kinetics experiments have been performed at lower and lower temperatures. Sub-ambient ...

Abstract Well‐ordered ultrathin films (UTFs) of {pyrenetetrasulfonate(PyTS)/ZnS}n were fabricated by alternating assembly of 1,3,6,8‐PyTS and exfoliated Zn2Al layered double hydroxide (LDH) nanosheets through layer‐by‐layer (LBL) electrostatic deposition, followed by an effective in situ ...

ABSTRACT We present a sensitive and quick way to determine benzene, toluene and dimethylbenzene (BTEX) in air, applying a cataluminescence (CTL) sensor based on a nano‐sized composite material, γ‐Al2O3/PtO2. The factors that affect the sensor's performance were studied, including the ...

Most chemical transport models assume instantaneous equilibrium to represent gas-particle partitioning of semivolatile organic aerosol. This approach has been challenged by recent studies suggesting that secondary organic aerosol (SOA) cannot reach equilibrium within atmospheric time scales. ...

A new implementation of pump–probe polarization spectroscopy is presented where the revivals of an impulsively excited rotational wavepacket are mapped onto a broad-band, chirped continuum pulse to measure a long temporal window without the need for delay scanning. Experimental measurements ...

To understand the prenucleation stage of methane hydrate formation, we measured methane solubility under metastable conditions using molecular dynamics simulations. Three factors that influence solubility are considered: temperature, pressure, and the strength of the modeled van der Waals ...

The saturated vapor pressure of pure 3,5-dichloroaniline was measured from (10.25 to 95.81) kPa in the temperature range from (446.60 to 534.94) K using an ebulliometer. The results were fitted by an Antoine equation using a nonlinear least-squares regression method. The calculated saturated ...
