The thermal stability of the external invertase isoforms from Saccharomyces cerevisiae correlates with the surface charge density
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2012)
Understanding the effect of surface charge on the stability of proteins is one prerequisite for "tailoring" proteins with increased thermal stability. Here, we investigated the origin of the altered thermal stability ...
Studies on the interactions of bioactive quinone avarone and its methylamino derivatives with calf thymus DNA
(Elsevier, 2013)
The interactions of avarone, a quinone from the marine sponge Dysideaavara, and the methylamino derivatives of avarone (2), 3'-(methylamino)avarone (3) and 4'-(methylamino)avarone (4) with calf thymus DNA (CT-DNA) were ...
Influence of HDTMA/Bentonite Ratio on Phenol Electrooxidation
(Wiley-Blackwell, Hoboken, 2013)
In this article partial and complete substitution of cations in the interlayer region of clay with different amounts of hexadecyl trimethylammonium bromide (HDTMABr) was performed. The aim was to investigate the influence ...
A theoretical study of conformational flexibility, magnetic properties, and polarizabilities of trimethylnaphthalenes
(Wiley-Blackwell, Hoboken, 2013)
For almost all trimethylnaphthalenes (TMNs), the transition from a planar equilibrium ring conformation to a nonplanar conformation characterized by the torsional angle of 20 degrees results in an energy increase of less ...
Detection limit for an adsorption-based mercury sensor
(Elsevier, 2013)
A novel readout procedure for the determination of detection limit at an adsorption-based mercury sensor is described. The procedure is based on the evaluation of the initial voltage slope in time evolution of adsorbed ...
Modeling of kinetics of pertechnetate removal by amino-functionalized glycidyl methacrylate copolymer
(Springer Verlag, 2012)
Technetium-99 comprises a significant health risk, since edible plants can bioaccumulate and convert it to more lipophilic species that cannot be excreted through urine. Batch kinetics of pertechnetate removal from aqueous ...
Speciation of Sr-90 and other metal cations in artificially contaminated soils: the influence of bone sorbent addition
(Springer Heidelberg, Heidelberg, 2013)
The influence of bone sorbent addition onto distribution of Sr-90 in artificially contaminated soil was preliminary studied to assess the possibility of biogenic apatite utilization for reduction of Sr-90 mobility and ...
The electrochemical behavior of PtRu- and Pt-modified zeolite X in alkaline solution
(Springer, New York, 2013)
Zeolite NaX was modified by Pt and Pt/Ru nanodispersed metallic clusters. The procedure of impregnation with acetylacetonate salt/acetone solution was applied. Scanning electron microscope analysis confirmed partial zeolite ...
Configurational, LFDFT and NBO analysis of chromium(III) complexes of edta-type ligands
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
A new hexadentate chromium(III) complex, Na[Cr(1,3-pd3ap)]center dot 3H(2)O, containing an unsymmetrical edta-type ligand, the 1,3-propanediamine-N,N,N'-triacetate-N'-3-propionate ion (1,3-pd3ap), has been prepared, ...
Mechanistic investigation and DFT calculation of the new reaction between S-methylisothiosemicarbazide and methyl acetoacetate
(Springer/Plenum Publishers, New York, 2013)
A study on the synthesis and mechanistical aspects of formation of 3-methyl-5-oxo-3-pyrazolin-1-carboxamide (MOPC) starting from S-methylisothiosemicarbazide hydrogen iodide and methyl acetoacetate was performed. In the ...
