Utilization of statistical analysis of FT-IR spectra in forensic examination of paper

Autor: Radko Tiňo, Štefan Šutý, Katarína Vizárová, Jana Provazníková, Soňa Kirschnerová

Publikováno v: Chemical Papers. 72:2265-2272

Studying of paper carriers of information has become increasingly important in forensic practice. This is caused by growing number of bogus or in other manner fraudulently alternated documents. An identification of individual paper sheets and studyin

Autor: Peter Šimon, Radoslav Mikulášik, András Peller, Katarína Vizárová, Soňa Kirschnerová, Milena Reháková

Publikováno v: Journal of Cultural Heritage. 12:190-195

In the restoration of a baroque altar painting “Coronation of the Virgin Mary” originating in the 18th century, a selection of materials was based on the examination of their stability evaluated by objective physico-chemical methods and by visual

Relationship between the decrease of degree of polymerisation of cellulose and the loss of groundwood pulp paper mechanical properties during accelerated ageing

Autor: Štefan Šutý, Katarína Vizárová, Anna Briškárová, Svetozár Katuščák, Soňa Kirschnerová, František Kačík

Publikováno v: Chemical Papers. 66

During natural ageing, paper undergoes colour changes and becomes brittle. It is mainly due to the degradation of cellulose, the main component of paper fibres. From the viewpoint of conservation/protection of paper-based information carriers, as wel

Xylan sulphate derivatives with degree of substitution (DS) up to 1.40 at 90% yield for film applications were prepared. The structure and substitution were confirmed by 2D NMR spectroscopy and elemental analysis. The highest DS was obtained by sulph
