As a result of investigations carried out in INCT on some applications of new fungicides containing QAC as a component, large group of new silica based materials based on this compound were obtained (SiO2-QAC). Preliminary biological tests showed strong biocidal activity of new SiO2-QAC materials on fungi and algae. It's possible to use them for numerous applications like: water reservoir or various surfaces desinfection, preventing objects from harmful biological agents by application of paints containing SiO2-QAC. Very economical materials based on water glass were obtained as well. Structure of these materials, especially origin of binding QAC with SiO2 as well as mechanism of biocidal activity of SiO2-QAC is under investigation. The materials also show high affinity to heavy metals and due to this fact can be applied as sorbents.

The object of the investigation is the so called Madonna Jackowa, or St. Hyacinthus's Madonna, a gothic alabaster figurine dated from the XIVth century. The purpose of the investigation is to provide an answer to the question whether Madonna Jackowa was made of native alabaster. Samples of alabaster from five various quarries located along the line Cracow-Lvov as well as in Lower Silesia were analyzed and the content of trace elements was compared with that of the sculpture. The determination of trace elements was carried out by means of the instrumental neutron activation analysis.
