Opis:: The paper presents practical utilisation in the construction of a parking lot of compositions based on waste (phosphogypsum) from the wet process of orthophosphoric acid manufacture. The results of strength tests performed after half a year and after one and a half year of parking lot operation confirmed the feasibility, established earlier in laboratory tests, of utilising phosphogypsum mixes with fly ash and stabilising binder.

Opis:: Most recently it has been found that nanodiamond particles have very interesting properties. There are number of research communications that detonation nanodiamond particles (NDPs) are fairly reactive and their surface can be effectively modified by chemical methods. The hydroxyl-modified NDPs were obtained by Fenton reaction, amine-functionalized NDPs were obtained by chemical reduction of the nitro- -functionalized surface and carboxyl-modified NDPs by oxidation by using H2O2 under acidic conditions. NDPs functionalized by hydroxyl- and amine- groups and amino groups were used for covalent binding of non-steroidal anti-inflammatory pharmaceuticals (aspirin, ketoprofen, ibuprofen, naproxen) via ester or amide bonds. These results of the studies proved the activity of the conjugates of active substance-NDP and study the rate of release of active substance from the NDPs surface by in vitro examinations with mouse fibroblasts. The progress of the reaction and the characteristics of the products were determined by using FT-IR. Chemical and physical structures of materials were also investigated by Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS). DRIFT spectra show the modification of nanodiamond by ketoprofen, naproxen, ibuprofen and aspirin.
