In 1985, she was recipient of Doctor Technical Science title from ICHRI; and in 2012, she received a DSc Chemistry Faculty of Cracow University. Since 2010, she started to cooperate with The Institute for Engineering of Polymers Materials and Dyes (IIMPaD) and since 2015 is General Director of IIMPaD. She completed International Centre of Physics and Chemistry in Ferrara-Roma (Italy) and International Professional Course for Managers of Chemical and Pharmaceutical Industry in Copenhagen (Denmark)-Washington (US). She is the author of more than 80 original research publications and author 90 scientific presentations in international conferences. She is also author (or co-author) of 65 patents/patent applications. She has coordinated Polish and international conferences, 23 research projects oriented towards new polymer materials. Her scientific activity concentrates on ecological aspect of technology and modification polymeric materials, particularly on fire retardant and reduced smoke toxic emission from thermoset resins systems.

Abstract:

The thermoset resins are proven construction materials for the technical and highly demanding applications. Heat stability, high thermal, low shrinkage, mechanical properties are typical for their type of polymers. Above applications also requires a good flame retardant (FR). Undertaken activities refer to official draft recommendations in UE states. This paper presents positive effect of reduced flammability of thermoset resins thanks to the use of nanocomposites containing multi-ingredient halogen-free flame retardants which combine phosphorus/nitrogen modifiers interacting with nanofillers: Expandable graphite (EG), graphene (G), graphene oxide (GO) and anthracite (AN). The flame retardancy of modified polymers has been investigated by LOI analysis, TG and by using CC method. The fine-plates, phase morphology of nanocomposites were assessed by SEM. We confirm that nanocomposite formation is an important concept for the flame retardants industry. Laminates made of modified resins meet requirement LOI over 28-34% and reduced 30-70% head release rate (HRR) by CC method. No adverse impact on strength properties was observed. A multi-ingredient combination of FR turned out to make significant progress in achieving a desired flammability. It should be assumed that the presence of conventional flame retardants led to a synergy effect promoting faster formation of a protection layer hindering oxygen flow-through resulting from the process of thermal destruction

Abstract:

Archaeosomes (ARC) are lipid vesicles composed by polar archaeolipids (TPA) extracted from hyperhalopileachae bacteria. In an "in vivo" context, inhaled ARC must first interact with the pulmonary surfactants (PS) lining layer covering the internal surface of the alveolus. Interactions of ARCs with the PS film determine the subsequent retention and translocation of the inhaled ARC and hence their potential activity on target cells. As in the respiratory cycle, the surface pressure of the surfactant monolayer changes, interaction was measured at different initial surface pressures. The changes were pronounced at low surface pressure (10 mN/m), where ARCs produce a much more noticeable effect in comparison to than hydrogenated soy phosphatidylcholine liposomes (L). Moreover, ARC incorporation rate into the PS membrane was two-fold effective when they were added from the air phase above the monolayer in comparison to when they were injected in the aqueous subphase underneath it. This makes ARC excellent candidates for delivering drugs to the lungs as inhaled nanoliposomes since they appear to interact with the hydrophobic moiety of PS

Abstract:

Iron oxides are environmental and human-friendly materials. They show various electrical, optical and magnetic properties. Highly spin polarized electron conductivities and unique photovoltaic behaviors are reported in a view point of spintronics technology. The efficient use of solar energy is now one of the great challenges in science and technology. In these days, variety materials have been investigated for use as photo-anodes for water-splitting by sunlight. Among these materials, ferrite oxide such as Fe2O3 and Fe3O4 are regarded as a promising system because of their probabilities of bandgap engineering, which lie well within the visible-IR spectrum, as well as their low costs, electrochemical stabilities and environmental compatibilities. Therefore, a considerable number of studies have been performed on the photoelectrochemical (PEC) properties of α-Fe2O3. We have demonstrated that enhanced photocurrent in Rh-substituted α-Fe2O3 thin films are grown by a pulsed laser deposition. The Rh-substituted and V-substituted α-Fe2O3 films were grown on α-Al2O3 (110) substrates with a Ta-doped SnO2 electrode layer by pulsed laser deposition. The optical absorption spectra of the films indicate narrowing of the bandgap with increasing Rh and/or V content. Consequently, the photoelectrochemical performance was improved in the Rh, V-substituted films. We found that the optimum Rh content lies at around x=0.2, where the photocurrent is significantly enhanced over a wavelength range of 340–900 nm. The findings of this research are expected to be useful in the development of the solar fuel conversion systems based on α-Fe2O3.
