Effect of pressure on the flow behavior of polybutene

18-03-2014 | Aleks Ponjavic, Luca Mare, Janet S. S. Wong, Journal of Polymer Science Part B: Polymer Physics, 2014

ABSTRACT The rheology of submicron thick polymer melt is examined under high normal pressure conditions by a recently developed photobleached‐fluorescence imaging velocimetry technique. In particular, the validity and limitation of Reynold equation solution, which suggests a linear ...

Stretching and conformal bonding of organic solar cells to hemispherical surfaces

28-12-2013 | Timothy F. O'Connor; Aliaksandr V. Zaretski; Bijan A. Shiravi; Suchol Savagatrup; Adam D. Printz; Mare Ivana Diaz; D ..., Energy & Environmental Science, 2013

This paper describes the stretching and conformal bonding (i.e., decal-transfer printing) of organic solar cells in both the “conventional” and “inverted” configurations to hemispherical glass surfaces with radii of 8 mm. This action produces equivalent biaxial tensile strains of 24%, which many ...

A Screening of Class IIa Bacteriocins Produced by Lactic Acid Bacteria Isolated from Fermented Mare Milk

16-10-2013 | Yanhua Cui, Chao Zhang, Chao Wang, Xiaomeng Lv, Zhangting Chen, Zhongqing Ding, Yunfeng Wang, Hongyu Cui, Journal of Food Safety, 2013

Abstract Twelve fermented mare milk samples were screened for class IIa bacteriocins based on a polymerase chain reaction (PCR) method. The positive PCR products were cloned and sequenced...

Persistence and origin of the lunar core dynamo [Earth, Atmospheric, and Planetary Sciences]

21-05-2013 | Clément Suavet; Benjamin P. Weiss; William S. Cassata; David L. Shuster; Jérôme Gattacceca; Lindsey Chan; Ian Garric ..., Proceedings of the National Academy of Sciences current issue, 2013

The lifetime of the ancient lunar core dynamo has implications for its power source and the mechanism of field generation. Here, we report analyses of two 3.56-Gy-old mare basalts demonstrating...

Prediction of ortho substituent effect in alkaline hydrolysis of substituted phenyl benzoates in aqueous acetonitrile

15-03-2013 | Vilve Nummert, Mare Piirsalu, Ilmar A. Koppel, Journal of Physical Organic Chemistry, 2013

The second‐order rate constants k (dm3mol−1s−1) for alkaline hydrolysis of meta‐, para‐ and ortho‐substituted phenyl esters of benzoic acid, C6H5CO2C6H4‐X, in aqueous 50.9% (v/v) acetonitrile have been measured spectrophotometrically at 25 °C. In substituted phenyl benzoates, C6H5CO2C6H4‐X, the ...

Predictive Models for the Growth Kinetics of Listeria monocytogenes on White Cabbage

18-01-2013 | Jun Wang, S.M.E. Rahman, Xi‐Hong Zhao, Fereidoun Forghani, Myoung‐Su Park, Deog‐Hwan Oh, Journal of Food Safety, 2013

by median relative error (MRE), mean absolute relative error (MARE) and %standard error of prediction (%SEP). The results indicated that Baranyi model described the growth of L. monocytogenes on white cabbage...

Effect of processing treatments (frozen, frying) on contents of minerals in tissues of ‘frutti di mare

11-09-2012 | Czech Anna, Stachyra Kamila, International Journal of Food Science & Technology, 2012

Summary The objective of this study was to determine the effect of thermal treatment (frying) of frozen seafood on the content of minerals and heavy metals. An analysis was conducted to compare concentration of sodium, magnesium, potassium, calcium, copper, iron, manganese, zinc, as well as ...

17O NMR studies of ortho‐substituent effects in substituted phenyl tosylates

31-08-2012 | Vilve Nummert, Vahur Mäemets, Mare Piirsalu, Ilmar A. Koppel, Magnetic Resonance in Chemistry, 2012

17O NMR spectra for 35 ortho‐, para‐, and meta‐substituted phenyl tosylates (phenyl 4‐methylbenzenesulfonates), 4‐CH3‐C6H4SO2OC6H4‐X, at natural abundance in acetonitrile at 50 °C were recorded. The 17O NMR chemical shifts, δ(17O), of the sulfonyl (SO2) and the single‐bonded phenoxy (OPh) ...

DrugLogit: Logistic Discrimination between Drugs and Nondrugs Including Disease-Specificity by Assigning Probabilities Based on Molecular Properties

07-08-2012 | Alfonso T. García-Sosa; Mare Oja; Csaba Hetényi; Uko Maran, Journal of Chemical Information and Modeling, 2012

The increasing knowledge of both structure and activity of compounds provides a good basis for enhancing the pharmacological characterization of chemical libraries. In addition, pharmacology can be seen as incorporating both advances from molecular biology as well as chemical sciences, with ...
