A working hypothesis for the development of a new construction material based on cement (C) using expanded polystyrene (PPS), technical carbon (TC) and foaming agent (PU) is proposed.The issue improving economic energy indicators due to use building created basis synergistic effect positive characteristics cement, polystyrene, discussed, effectiveness each these materials considered.The main li...

Global air pollution is a serious threat caused by excessive use of fossil fuels for transportation. Despite the fact that diesel fuel is a big environmental pollutant as it contains different hydrocarbons, sulphur and crude oil residues, it is yet regarded as a highly critical fuel due to its wide applications. Nowadays, biodiesel as a renewable additive is blended with diesel fuel to achie...

The certification of a polystyrene standard reference material, SRM 2888, is described. The Mw of SRM 2888 was determined by light scattering to be 7.19x10 g/mol with a sample standard deviation of 0.14 x10 g/mol. A combined expanded uncertainty for this light scattering Mw determination, including systematic and random uncertainties, was estimated to be 0.57 x10 g/mol. Mn was determined by nuc...

Particle tracking analysis (PTA) is an emerging technique suitable for size analysis of particles with external dimensions in the nano- and sub-micrometre scale range. Only limited attempts have so far been made to investigate and quantify the performance of the PTA method for particle size analysis. This article presents the results of a validation study during which selected colloidal silica ...
