PHASE TRANSITION OF HEXAGONAL BE NANOCRYSTAL INTO CUBIC SUPERLATTICE UNDER X-RAY RADIATION

(STEF92 Technology, 2018-06-20, Mels Boranbayev)

Show more

The structure and phase composition of annealed and irradiated beryllium plates were studied by X-ray analysis. Durable X-ray irradiation leads to phase transition of a normal hexagonal beryllium lattice into a beryllium superlattice. This superlattice is composed of beryllium superatoms that form a face-centered cubic lattice with the lattice parameter of 6.2205 ? and a superatom core that crystalizes into a diamond-type lattice with the lattice parameter of 1.5703?. It is shown that beryllium has three phase sta...

(STEF92 Technology, 2018-06-20, Kateřina Schrimpelová)

Show more

The water pollution caused by nutrients has become a problem, especially in agricultural areas. Nitrogen (N) and phosphorus (P) can cause the eutrophication of surface waters, and problems with their use as drinking water sources. One of the possible solutions is to employ denitrifying bioreactors, which are used for the reduction of high nitrate concentrations in shallow groundwaters. Our research was focused on the enhancement of these bioreactors with steel byproducts. These materials release Fe, which causes t...

POLLUTION SOURCES LOCALISATION IN URBAN SEWER SYSTEMS.

(STEF92 Technology, 2018-06-20, Marek Sokáč)

Show more

Nowadays a typical task in water quality modelling is to simulate the pollution spreading downstream, i.e. initial and boundary conditions are known. However, in practice opposite problems may occur: pollution concentration time courses in specific locations are known (e.g. based on the on-line monitoring), but the position of the pollution source is unknown. This type of task can occur in case of accidental pollution and is named as an inverse task. Particular importance has the inverse task application in urban ...

Amines play an important role in the modern chemical engineering. It is a key intermediate for agricultural, pharmaceutical, textile, polymer and other fields of industry. Bio-basedamines, e.g. the derivatives of isohexides, are of a great attention. Nowadays, different methods of the synthesis of polyamides, polyimides, polyesters, polyurethanes, and polycarbonates on the base of isohexides are developed. Thus, mono- and diamine derivatives of D-isosorbide are considered to be a prospective feedstock for polyamid...

The authors of this article describe the suitability of using light dynamic penetration in the target area. The area of this survey was selected on the already reclaimed area, which, however, proved to be unstable. The main objective was to locate individual water-saturated horizons in the locality and, eventually, to determine the shear areas on which instability occurs. For this reason, several geodetically measured points were selected for dynamic penetration measurement. By this method, the water-saturated hor...

POSSIBLE USES OF COAL IN CIRCULAR ECONOMY

(STEF92 Technology, 2018-06-20, Mihai Cruceru)

Show more

Even if the European Commission estimates that the end-of-life recycling input rate for coking coal is zero, some initiatives proved that coal could play a role in circular economy. Coal-fired power plants still play a significant role in electricity generation although a lot of renewables were developed. Coal combustion produces a relatively small amount of fly ash that is used in cement factories and a large amount of bottom ash that cannot be used in industry because its high carbon content. From this point of ...
