A high-pressure rapid compression machine study of n-propylbenzene ignition
(Elsevier ScienceDirect, 2013-08-28)
This study presents new ignition delay data measured in a rapid compression machine over a wide range temperature, pressure and fuel/air ratio. This data is an extension of that measured previously (D. Darcy, C.J. Tobin, ...
On the equivariant K-homology of PSL_2 of the imaginary quadratic integers
(Association des Annales de l'Institut Fourier, 2016-09)
We establish formulae for the part due to torsion of the equivariant $K$-homology of all the Bianchi groups (PSL$_2$ of the imaginary quadratic integers), in terms of elementary number-theoretic quantities. To achieve this, ...
Sulfamerazine: Understanding the influence of slip planes in the polymorphic phase transformation through X-ray crystallographic studies and ab initio lattice dynamics
(American Chemical Society, 2015-08-28)
Understanding the polymorphism exhibited by organic active-pharmaceutical ingredients (APIs), in particular the relationships between crystal structure and the thermodynamics of polymorph stability, is vital for the ...
The influence of co-formers on the dissolution rates of co-amorphous sulfamerazine/excipient systems
(Elsevier, 2016-03-16)
A comprehensive study on the dissolution properties of three co-amorphous sulfamerazine/excipient systems, namely sulfamerazine/deoxycholic acid, sulfamerazine/citric acid and sulfamerazine/sodium taurocholate (SMZ/DA, ...
DNA damage and induction of apoptosis in pancreatic cancer cells by a new dinuclear bis(triazacyclonane) copper complex
(Elsevier, 2015-01-26)
The dinuclear copper(II) complex [Cu-2{bcmp(-H)}(mu-OH)](NO3)(2)center dot H2O (1, bcmp = 2,6-bis(1,4,7-triazacyclonon-1-ylmethyl)-4-methylphenol) has been synthesized and characterized by electrospray ionization mass ...
Unexpected effects of catalytic amounts of additives on crystallization from the gas phase: Depression of the sublimation temperature and polymorph control
(American Chemical Society, 2016-04-11)
Sublimation of carbamazepine, piracetam, diflunisal, and p-minobenzoic acid is enhanced by the presence of additives. Temperature reductions and polymorph control have been observed. Sublimation of carbamazepine containing ...
Solid-state transformations of sulfathiazole polymorphs: The effects of milling and humidity
(American Chemical Society, 2013-07-11)
The effect of milling on the transitions of sulfathiazole polymorphs in the absence and presence of solvent and excipients was monitored by X-ray powder diffraction (XRPD), attenuated total reflectance infrared (ATR-IR), ...
Phosphate diester cleavage, DNA interaction and cytotoxic Activity of a bimetallic bis(1,4,7-triazacyclononane) zinc complex
(Wiley, 2014-06-24)
The dinuclear zinc complex [Zn-2{bcmp(-H)}(mu-Cl)](ClO4)(2)center dot H2O {bcmp = 2,6-bis(1,4,7-triazacyclonon-1-ylmethyl)-4-methylphenol} has been synthesized and structurally characterized. The DNA binding affinity was ...
Cytotoxicity and antimicrobial activity of triorganotin(IV) complexes of phenylcyanamide prepared by sonochemical synthesis
(Elsevier, 2015-09-25)
This article describes the synthesis and characterization of novel triorganotin(IV) complexes and their potential medicinal applications. Triorganotin(IV) complexes with formulas [(SnMe3)(2)(mu-bp)(H2O)(2)], 1, and ...
Formation, physical stability, and quantification of process-induced disorder in cryomilled samples of a model polymorphic drug
(Elsevier, 2012-10-09)
The formation and physical stability of amorphous sulfathiazole obtained from polymorphic forms I and III by cryomilling was investigated by X-ray powder diffraction (XRPD) and near-infrared (NIR) spectroscopy. Principal ...
