Manousakas M, Papaefthymiou H, Diapouli E, Migliori A, Karydas AG, Bogdanovic-Radovic I, Eleftheriadis K.
PMID: 27631196
Sci Total Environ. 2017 Jan 01;574:155-164. doi: 10.1016/j.scitotenv.2016.09.047. Epub 2016 Oct 14.

Datasets that include only the PM elemental composition and no other important constituents such as ions and OC, should be treated carefully when used for source apportionment. This work is demonstrating how a source apportionment study utilizing PMF 5.0...

Variations of nanoparticle concentrations at the Fresno Supersite.

The Science of the total environment

Watson JG, Chow JC, Lowenthal DH, Kreisberg NM, Hering SV, Stolzenburg MR.
PMID: 15990156
Sci Total Environ. 2006 Apr 01;358(1):178-87. doi: 10.1016/j.scitotenv.2005.04.046. Epub 2005 Jun 28.

Particle size distributions from 3 nm to 2 mum were measured at the Fresno, CA, Supersite from August 25, 2002 through July 31, 2003. Nanoparticle (3-10 nm) concentrations and the ratio of nanoparticle to total particle concentration were inversely...

Nitric oxide-assisted atmospheric pressure corona discharge ionization for the analysis of automobile hydrocarbon emission species.

Journal of the American Society for Mass Spectrometry

Dearth MA, Komiski TJ.
PMID: 24226517
J Am Soc Mass Spectrom. 1994 Dec;5(12):1107-14. doi: 10.1016/1044-0305(94)85072-0.

Nitric oxide reagent gas has been found to improve the sensitivity and robustness of the atmospheric pressure corona discharge ionization (APCDI) process. Sensitivity has been increased by a factor of 20-100, depending on the compound, over APCDI without nitric...

TiO2 supported Pd@Ag as highly selective catalysts for hydrogenation of acetylene in excess ethylene.

Chemical communications (Cambridge, England)

Han Y, Peng D, Xu Z, Wan H, Zheng S, Zhu D.
PMID: 23929310
Chem Commun (Camb). 2013 Sep 28;49(75):8350-2. doi: 10.1039/c3cc43511c.

A novel TiO2 supported core-shell (Pd@Ag) bimetallic catalyst was fabricated via the sequential photodeposition method. The Ag shell effectively blocks the high coordination sites on the Pd core, and therefore pronouncedly enhances the ethylene selectivity for the catalytic hydrogenation...
