Biological evaluation and comparison of three different procedures for labelling of amino acids tyrosine and lysine with technetium-99m
(Journal of Labelled Compounds and Radiopharmaceuticals, 2007)
The Tc-99m-labelling of the amino acids tyrosine (Tyr) and lysine (Lys), fundamental building blocks of proteins and peptides, as well as biological properties of the labelled compounds are investigated. Three different ...
A consideration of the correct calculation of thermodynamic parameters of adsorption
(Journal of the Serbian Chemical Society, 2007)
The Langmuir and Freundlich isotherm equations have been widely used for interpreting various adsorption processes. There are, however, many serious mistakes in the literature in determination or calculation of thermodynamic ...
