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 ...

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.

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 ...
