We report the results of a DFT study of the border oxidation by (1) Δg O2 of molecular models of armchair graphene nanoribbons (a-GNRs). The aim of this work is to propose a new method, as an alternative or...

Characterizing particulate polycyclic aromatic hydrocarbon emissions from diesel vehicles using a portable emissions measurement system.

Scientific reports

Zheng X, Wu Y, Zhang S, Hu J, Zhang KM, Li Z, He L, Hao J.
PMID: 28855647
Sci Rep. 2017 Aug 30;7(1):10058. doi: 10.1038/s41598-017-09822-w.

Particulate polycyclic aromatic hydrocarbons (p-PAHs) emitted from diesel vehicles are of concern because of their significant health impacts. Laboratory tests, road tunnel and roadside experiments have been conducted to measure p-PAH emissions. While providing valuable information, these methods have...

One-Pot Approach to Prepare Organo-silica Hybrid Capillary Monolithic Column with Intact Mesoporous Silica Nanoparticle as Building Block.

Scientific reports

PMID: 27698475
Sci Rep. 2016 Oct 04;6:34718. doi: 10.1038/srep34718.

A facile "one-pot" approach to prepare organo-silica hybrid capillary monolithic column with intact mesoporous silica nanoparticle (IMSN) as crosslinker and building block was described. An IMSN crosslinked octadecyl-silica hybrid capillary monolithic column (IMSN-C18 monolithic column) was successfully prepared, and...

Assessment of the effects of phenanthrene and its nitrogen heterocyclic analogues on microbial activity in soil.
