	abstract = {The impact resistance of four polypropylene impact copolymers (ICPs) with multi-phase structures and widely differing characteristics was related to their structure. Blends were prepared from one of them and a high-density polyethylene (HDPE) to improve impact strength further. The structure of the materials was characterized by microscopy and dynamic mechanical thermal analysis. Mechanical properties were determined by tensile and impact testing, while local deformation processes were followed by volume strain measurements. The results obtained in the study proved that the shear-yielding of the matrix contributes the most among local processes to the increase of impact strength, while cavitation has a small effect on this latter property since its energy absorption is negligible. Both increasing elastomer content and decreasing particle size favor shear-yielding, thus improving impact strength. Considering the importance of elastomer content and elastomer particle size, a simple but very good model was created describing the dependence of the impact strength of ICPs on these latter two factors by using linear regression analysis. Although the addition of HDPE increases the fracture resistance of ICPs further, the extent of improvement is moderate, and the approach is economically disadvantageous. © BME-PT.},

	abstract = {The winery waste of a white grape was extracted in two different ways to produce extracts, one containing the natural oil of the waste and one without it; the goal of the work was to determine the positive or negative influence of the natural oil content of the extract on its stabilization effect and efficiency. The polyphenol content of the extracts was moderate, but their DPPH assay proved their antioxidant effect. The two extracts were added to polyethylene in concentrations between 0 and 2000 ppm, and their stabilizing efficiency was determined in multiple extrusion experiments. The extracts stabilized polyethylene adequately; their efficiency was only slightly smaller than that of the commercial hindered phenolic antioxidant, Irganox 1010. The solubility of the extracts in PE is much larger, 280 ppm, than that of a flavonoid-type natural antioxidant, quercetin (15 ppm). The presence of the oil had only a slight effect on stabilization efficiency, and its influence on properties is more beneficial than harmful. It decreases interactions among polyphenol molecules, improves the processability of the polymer, and increases homogeneity slightly. Accordingly, an extraction step can be saved during the preparation of the product, thus offering an economic advantage. © 2024 The Author(s)},

	abstract = {To explore the possibility of applying lignin in practice, an industrial lignosulfonate (0–50 vol%) was blended
		with four ionomers. The concentrations of carboxyl and carboxylate groups were systematically varied in the
		ethylene-acrylic acid copolymers to study the competition of hydrogen and ionic bonds forming between the
		components. The mechanical properties of the blends were determined by tensile testing. The structure was
		investigated by scanning electron microscopy, while deformation and failure processes were studied by acoustic
		emission measurements and microscopy. Interfacial interactions were quantitatively characterized by analyzing
		local deformation processes and by evaluating the composition dependence of the tensile strength using
		appropriate models. Molecular dynamics simulations indicated that carboxylate groups preferably form clusters
		in the ionomer phase, consequently, the increasing degree of neutralization results in ionomers with more and
		more self-interactions of components deteriorating ionomer-lignin interactions. The novel combination of ex-
		periments, modeling, and simulation was done for the first time on such materials, and it pointed out that the role
		of hydrogen bonds is more critical in determining blend properties. Blends can be prepared for practical ap-
		plications with a good combination of stiffness (0.8 GPa), tensile strength (22 MPa), and elongation-at-break (25
		%) at 30 vol% lignosulfonate content and 33 % neutralization},

	abstract = {Electrospun fibers containing levocetirizine, a BCS III drug, were prepared from three water-soluble polymers, hydroxypropyl methylcellulose (HPMC), polyvinylpyrrolidone (PVP) and polyvinyl alcohol (PVA). Fiber-spinning technology was optimized for each polymer separately. The polymers contained 10 wt% of the active component. An amorphous drug was homogeneously distributed within the fibers. The solubility of the drug in the polymers used was limited, with a maximum of 2.0 wt%, but it was very large in most of the solvents used for fiber spinning and in the dissolution media. The thickness of the fibers was uniform and the presence of the drug basically did not influence it at all. The fiber diameters were in the same range, although somewhat thinner fibers could be prepared from PVA than from the other two polymers. The results showed that the drug was amorphous in the fibers. Most of the drug was located within the fibers, probably as a separate phase; the encapsulation efficiency proved to be 80–90%. The kinetics of the drug release were evaluated quantitatively by the Noyes–Whitney model. The released drug was approximately the same for all the polymers under all conditions (pH), and it changed somewhere between 80 and 100%. The release rate depended both on the type of polymer and pH and varied between 0.1 and 0.9 min−1. Consequently, the selection of the carrier polymer allowed for the adjustment of the release rate according to the requirements, thus justifying the use of electrospun fibers as carrier materials for levocetirizine.},
