Emission enhancement of Eu(III) and/or Tb(III) ions entrapped in silica xerogels with ZnO nanoparticles by energy transfer
PublicationW pracy przedstawiono rezultaty wpływu domieszkowania nanocząsteczkami ZnO kserożeli krzemianowych zawierających jony Eu(III)i/lub Tb(III). Wzmocnienie emisji w kserożelach zawierających Tb(III) następowało na skutek wymiany energii między jonami Tb i nanocząsteczkami ZnO. Wzmocnienia takiego nie zaobserwowano w przypadku jonów Eu. Zaobserwowano również kwantowy efekt rozmiaru w przerwie energetycznej ZnO.

Polycyclic aromatic hydrocarbons as test probes to investigate the retention behavior of 1,3-alternate calix[4]arene silica-bonded stationary phases
PublicationA series of polycyclic aromatic hydrocarbons (PAHs) of different size and shape has been used to characterize the chromatographic behavior of five calix[4]arene stationary phases in 1,3-alternate conformation synthesized in our laboratory. The selection of linear, fourring nonlinear, and five-ring PAHs gave data on selectivity changes across range of the calix[4]arene columns. Retention of the 12 aromatic solutes has been evaluated...

The impact of natural fibers’ characteristics on mechanical properties of the cement composites
PublicationThe paper reviews the properties of cement composites reinforced with short fibres. The effect of natural fibres was investigated: cotton, sisal, jute, ramie, bamboo, and synthetic fibres: polymer and polypropylene. It was noticed that the fibres change the consistency of the mixture up to 15%. In the composite flexural strength tests, a change in strength by +/− 8% was observed, depending on the type of fibres used. The research...
