Natural lignite from South Moravia was tested for the sorption of fluoride anion in concentration range from 0.05 to 0.8 mmol/l. The lignite removes majority of fluorides and only about 13% of sorption is reversible upon ...

Aggregation properties of hydrophobized hyaluronan (hHA) in different molecular weights and degree of substitution were studied by pyrene and perylene fluorescence method. The critical aggregation concentration (cac) was ...

Detailed balance condition for triangular isomerisation mechanism is derived from the more general permanence of atoms, consequently, it should be viewed as a special equilibrium result of mass conservation.
