Quantitative Chemistry, Biochemistry and Biology 
Steps Ahead

The monk Jesuit Escober proposed the slogan "The aim justifies the means". This slogan at large is not correct because it permits any action. However in this particular case, this slogan is acceptable because the aim is to target the reader. Reviews and original papers were collected about quantitative chemistry, biochemistry and biology. Special attention is given to new ideas in the fields which include nanoelements formation and reactivity, synthesis of thermoplastic bio-based polyurethanes on the basis of vegetable oils, carvacrol and thymol for fresh food packaging, polymer composites structure and electric properties and some properties of small water clusters in water-starch systems. The following topics are also discussed: investigation of kinetics and mechanism of biologically awake antioxidants in reaction to esterification 2- (n-acetylamid)-3-(3 ’, 5 ’-di-tert.butyl-4 ’-hydroxyphenyl)-propionic acid, the turbulent apparatus for oil neutralization, uffect melaphen on a mitochondria of sprouts of peas under stressful influences by some methods, preparation of new antioxidants in reaction 2- (n-methylamide)-3- (3 ’, 5 ’-di-tert.butyl-4 ’-hydroxyphenyl)-propionic acid and effect of external influences on the structural and dynamic parameters of polyhydroxybutyrate-hydroxyvalerate-based biocomposites. Also mentioned include the problems of determination diffusion coefficients of Brownian particles using velocity or force autocorrelation function in molecular dynamic simulations, in silico simulation of silver and copper ions interacting with fungal cell wall (in vitro antifungal activity of copper ions and silver ions) and the estimation of antioxidants as nuts quality index and the structure of soluble unlinked and cross-linked fibrin oligomers.
