    Characterisation of Polacrylate-Polysacharide System. Part I. Infrared Structural Studies
    (Wydawnictwa AGH, 2024) Kaczmarska, Karolina; Śmietana, Mateusz; Drożyński, Dariusz; Woźniak, Faustyna; Bobrowski, Artur
    For the prepared polymer systems based on an poly(acrylic acid) and a colloidal solution of native starch, a series of IR (FTIR) structural studies and tests under heating conditions (ATR-FTIR) were carried out. Two components from the group of native starch of different biological origin (potato, cassava) were selected. The analysis of the collected results was aimed at assessing the effect of the biological origin of the starch on the structure, thermal sensitivity of the acrylic polymer-based system. On the basis of interaction effects occurring in the obtained synthetic polymer-natural polymer systems, the validity of mixing selected components to obtain composition was verified.

    The following work concerns an important issue from the environment protection point of view - recycling the dust from dry dust extraction of green sand processing plant, which is a by-product of casting in green sand. The subject of the work is very up-to-date because of European Union requirements in the range of Best Available Techniques. Three ways of recycling dust were suggested. Vast structural, physicochemical, and technological researches were performed. Appraisal of the influence of dust addition to moulding sand on the natural environment was conducted (EGA examination, gases emission, and leaching).

    Detection of nitrates(V) and sulfates(VI) by UV-Vis spectrophotometry method in used green sand bonded by bentonite with modified starch addition
    (Wydawnictwa AGH, 2016) Grabowska, Beata; Kurleto-Kozioł, Żaneta; Szymański, Łukasz; Kaczmarska, Karolina; Bobrowski, Artur
    The research results (SEM, UV-Vis) that contain a part of the work connected with determining the influence of a modified starch addition on the physical and chemical property changes of green sands (including the emission levels of harmful substances from the used molding sands formed as a result of the liquid metal pouring of molds) are presented in this paper. A surface analysis (SEM) was performed for the fresh molding sands and used molding sands with and without modified starch samples. On the bases of the received microscopic images, the impact of the temperature factor on the morphology of the molding sand samples after the liquid metal pour- ing process are assessed. In the second part of the performed work on the UV-Vis research, eluates from two used molding sands (green sand [sand number 1] and green sand with the addition of a modified starch [sand number 2]) were tested for nitrate and sulfate content. In order to deter- mine whether the level of nitrate and sulfate elusion from the used molding sands is permissible, the received results were compared with the Minister of Environment’s regulations concerning the requirements of surface waters used for supplying the population with potable water.

    FTIR method in studies of the resol-type phenol resin structure in the air atmosphere over certain time intervals
    (2015) Bobrowski, Artur; Grabowska, Beata
    This paper presents the results of structural-type studies of resol phenolic resin used for the preparation of molding and core sands exposed to air. The FTIR study was carried out using a transmittance technique. Recorded changes in the IR spectra of resin can indicate a progressive polycondensation process, the consequences of which being changes in the aromatic rings of methylene bridges (among others).

    Polylactide used as filment in 3D printing - Part 1: FTIR, DRIFT and TG-DTG studies
    (AGH University of Science and Technology Press, 2020) Grabowska, Beata; Kaczmarska, Karolina; Cukrowicz, Sylwia; Mączka, Elżbieta; Bobrowski, Artur
    A short literature review was undertaken in terms of the structure, properties and applications of polymers, including those commonly used in 3D printing. The research part included the structural and thermal analysis of polylactide (PLA), which is an example of an extensively used polymer in the developing 3D technology. Special attention was paid to the comparison of structure and thermal stability of two different (from various producers) polylactide samples. The research, involving such analytical methods as infrared spectroscopy (FTIR) and diffuse reflectance infrared spectroscopy (DRIFT), allowed the comparison of the structure of the two PLA samples considered. The determination of the temperature range in which changes related to PLA thermodestruction occur was a result of the performed thermoanalytical research (DRIFT, TG-DTG). Thermal studies also allowed to establish the temperature range in which the material does not yet degrade, which is important in the context of future planned research work on polylactide modification to obtain the improvement of the thermal and mechanical properties of PLA-based materials. This research area will be described in the second part of the publication.
