Viscosity measurements of ortho-xylene, meta-xylene, para-xylene and ethylbenzene [PDF]

open access: yesThe Journal of Chemical Thermodynamics, 2016
Abstract The compressed liquid viscosities of ortho-xylene, meta-xylene, para-xylene and ethylbenzene were measured using a vibrating-wire viscometer at different temperatures and pressures. The measurements were performed over the temperature ranges of (273 to 373) K for o-xylene and m-xylene, (293 to 373) K for p-xylene and (253 to 373) K for ...

Highly Efficient Separation of Intermediate-Size m-Xylene from Xylenes via a Length-Matched Metal-Organic Framework with Optimal Oxygen Sites Distribution.

open access: yesAngewandte Chemie
Xylene separation is crucial but challenging, especially for the preferential separation of the intermediate-size m-xylene from xylene mixtures. Herein, exploiting the differences in molecular length and alkyl distribution among xylenes, we present a ...

Characterization of volatile organic compounds at a roadside environment in Hong Kong: An investigation of influences after air pollution control strategies [PDF]

open access: yes, 2015
Vehicular emission is one of the important anthropogenic pollution sources for volatile organic compounds (VOCs). Four characterization campaigns were conducted at a representative urban roadside environment in Hong Kong between May 2011 and February ...

VOLATILE ORGANIC COMPOUNDS IN MOTOR VEHICLE INTERIORS UNDER VARIOUS CONDITIONS AND THEIR EFFECT ON HUMAN HEALTH [PDF]

open access: yesScientific Journal of Silesian University of Technology. Series Transport, 2020
The aim of this paper is to estimate the mass concentrations of volatile organic compounds (VOCs) such as benzene (B), toluene (T), ethylbenzene (E) and m-, p-, o-xylenes (X) inside of the driver-compartment of motor vehicles.

Design and fabrication of chemically robust three-dimensional microfluidic valves [PDF]

open access: yes, 2007
A current problem in microfluidics is that poly(dimethylsiloxane) (PDMS), used to fabricate many microfluidic devices, is not compatible with most organic solvents. Fluorinated compounds are more chemically robust than PDMS but, historically, it has been

Air quality in the Industrial Heartland of Alberta, Canada and potential impacts on human health. [PDF]

open access: yes, 2013
The "Industrial Heartland" of Alberta is Canada's largest hydrocarbon processing center, with more than 40 major chemical, petrochemical, and oil and gas facilities. Emissions from these industries affect local air quality and human health.

One-pot co-crystallization of beta and pentasil nanozeolites for the direct conversion of a heavy reformate fraction into xylenes

open access: yesApplied Catalysis A: General, 2019
Upgrading of the heavy reformate fraction (HR), containing mainly C9+ aromatics, is usually performed by dealkylation or by transalkylation with added benzene and/or toluene to obtain the more valuable xylenes.

Synthesis and Characterization of Nitro-p-xylenes

open access: yesMolecules, 2005
In this paper we elected to nitrate p-xylene because this compound has onlyone mononitro- and trinitro- isomer. Trinitro-p-xylene was used as a starting material forthe synthesis of other compounds in subsequent work.

On the use of an explicit chemical mechanism to dissect peroxy acetyl nitrate formation. [PDF]

open access: yes, 2014
Peroxy acetyl nitrate (PAN) is a key component of photochemical smog and plays an important role in atmospheric chemistry. Though it has been known that PAN is produced via reactions of nitrogen oxides (NOx) with some volatile organic compounds (VOCs ...

Identification of serum protein biomarkers for pre‐cancerous lesions associated with pancreatic ductal adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...
