A stainless steel multi-well plate (SS-MWP) for high-throughput Raman analysis of dilute solutions
(Wiley, 2010)The use of Raman spectroscopy for the qualitative and quantitative analysis of dilute aqueous solutions is of interest to the biopharmaceutical manufacturing sector. However, the inherent weakness of the Raman effect, ... -
Prediction of cell culture media performance using fluorescence spectroscopy.
(American Chemical Society, 2010)Cell culture media used in industrial mammalian cell culture are complex aqueous solutions that are inherently difficult to analyze comprehensively. The analysis of media quality and variance is of utmost importance in ... -
Ga-III Complexes as Models for the M-III Site of Purple Acid Phosphatase: Ligand Effects on the Hydrolytic Reactivity Toward Bis(2,4-dinitrophenyl) phosphate
(2010)The effects of a series of Galli complexes with tripodal ligands on the hydrolysis rate of the activated phosphate diester bis(2,4-dinitrophenyl)phosphate (BDNPP) have been investigated. In particular, the influence of the ... -
Monitoring local unfolding of bovine serum albumin during denaturation using steady-state and time-resolved fluorescence spectroscopy
(Springer, 2010-03)In a previous report (J. Fluoresc. 16, 153, 2006) we studied the chaotropiclly induced denaturation of Bovine Serum Albumin (BSA) using the fluorescence decay kinetics at different stages in the denaturation of BSA by ... -
A family of double-bowl pseudo metallocalix[6]arene discs
(RSC, 2010-03-10)We report the synthesis and magnetic characterisation of a series of planar [M7] (M = NiII, ZnII) disc complexes [Ni7(OH)6(L1)6](NO3)2 (1), [Ni7(OH)6(L1)6](NO3)2·2MeOH (2), [Ni7(OH)6(L1)6](NO3)2·3MeNO2 (3), [Ni7(OH)6(L2) ... -
Additive tuning redox potential in metallacarboranes by sequencial halogen substitution
(Wiley, 2010-04-21)The first artificially made set of electron acceptors is presented that are derived from a unique platform Cs[3,3′-Co(C2B9H11)2], for which the redox potential of each differs from its predecessor by a fixed amount. The ... -
Alternating bimetallic Na/Mn covalent and ionic chains
(RSC, 2010-07-30)The first coordination polymers constructed using the 2,2'-biphenol ligand are described along with their ionic supramolecular counterparts. -
SnCl4- and TiCl4-catalyzed anomerization of acylated O- and S-Glycosides: analysis of factors that lead to higher alpha:beta anomer ratios and reaction rates
(American Chemical Society, 2010-09-13)The quantification of factors that influence both rates and stereoselectivity of anomerization reactions catalyzed by SnCl4 and TiCl4 and how this has informed the synthesis of alpha-O- and alpha-S-glycolipids is discussed ... -
Planar [Ni-7] discs as double-bowl, pseudo metallacalix[6]arene host cavities
