Bacterial filtration efficiency of different masks
Tamara Košir, Katja Fric, Arijana Filipić, Polona Kogovšek
Izvirni znanstveni članek
Oznake: bacterial filtration efficiency;face coverings;masks;respirators;Andersen Cascade Impactor;EN 14683:2019;
Face coverings, such as surgical masks and respirators, have an important role in preventing bacterial and viral transmission, especially during a global pandemic like COVID-19. Therefore, to secure their availability, new manufacturers and the use of novel materials must be encouraged. However, mas ...

Arijana Filipić, Katja Fric, Maja Ravnikar, Polona Kogovšek
Izvirni znanstveni članek
Oznake: face masks;virus filtration efficiency;bacterial filtration efficiency;EN 14683:2019+AC:2019;air sampler;
Abstract As a result of the COVID-19 pandemic, many new materials and masks came onto the market. To determine their suitability, several standards specify which properties to test, including bacterial filtration efficiency (BFE), while none describe how to determine viral filtration efficiency (VF ...

Magistrsko delo
Oznake: transkripcijski faktor;Pti5;PR1b;krompir;konfokalni mikroskop;
Po okužbi krompirja s krompirjevim virusom PVY se transkripcijski faktor Pti5 premakne v jedro. Pti5 iz družine ERF (angl. ethylene response factors) ima glavno vlogo pri aktivaciji in utišanju tarčnih genov, ki so pomembni v odgovoru na stres. V magistrskem delu smo raziskovali mehanizem, ki sprož ...

Antiviral respiratory masks with plasma-functionalized polypropylene textiles for optimal adsorption of antiviral substance
Mark Zver, David Dobnik, Rok Zaplotnik, Miran Mozetič, Alenka Vesel, Arijana Filipić, Polona Kogovšek, Katja Fric, Alja Štraser, Gregor Primc
Izvirni znanstveni članek
Oznake: kirurške maske;protivirusni materiali;filtracija virusov;zračnost;surgical face masks;plasma functionalization;antiviral materials;virus filtration;breathability;
During the COVID-19 pandemic, face masks were the first line of defense against the spread of infection. However, infectious viruses may remain on medical textiles, potentially serving as an additional source of infection. Due to their chemical inertness, many textiles cannot be enhanced with antivi ...
