Opis:
Nowadays hydrogel materials are being used in medical practice for wound dressing purposes. Hydrogel/textile composites can be formed to increase the mechanical strength and handling capability of hydrogel materials. Nonwoven textiles are optional for such applications, however, it is often necessary to improve their surface properties. Here plasma activation/grafting of polypropylene (PP) nonwoven fabric with an acrylate layer to improve its adhesive properties is reported. A diaphragm discharge was used for the plasma treatment of the PP fabric. The discharge was burnt in a solution of acrylic acid (AAc), which resulted in a single step process of plasma activation and plasma grafting of the fabric. Results of wettability testing and ATR-FTIR measurements showed the existence of a thin poly(acrylic acid) (PAAc) layer grafted on the fabric surface. Peel strength measurements showed a 4.7 fold increase in the peel strength when compared with untreated PP fabric.
Współcześnie materiały hydrożelowe używane są w wyrobach medycznych jako opatrunki na rany. Hydrożelowe kompozyty tekstylne formuje się dla zwiększenia mechanicznej wytrzymałości poręczności w stosowaniu. Włókniny są powszechnie stosowane do wyrobów medycznych, jednak jest konieczne polepszenie ich właściwości powierzchniowych. W badaniach zastosowano aktywację plazmową w celu pokrycia włóknin polipropylenowych warstwą akrylową dla polepszenia właściwości adhezyjnych. Wyładowania odbywały się w roztworze kwasu akrylowego co pozwoliło na przeprowadzenie jednostopniowego procesu aktywacji plazmowej. Wyniki pomiarów zwilżalności oraz badania ATR-FTIR wykazały istnienie cienkiej warstwy kwasu poliakrylowego na powierzchni włókniny. Stwierdzono 4.7 razy większą wytrzymałość na odrywanie w stosunku do włóknin niemodyfikowanych.

Opis:
Self-propagating high-temperature synthesis is a simple and efficient method for the synthesis of various compounds including ceramics and intermetallics. In this process, the compressed mixture of elemental or master alloy powders is ignited or heated to initiate the exothermic reactions leading to the formation of desired compounds. In order to control the process efficiently, the effect of several important parameters has to be determined in each applied alloy system. Previous results showed that those parameters are: initiation temperature, process duration, pressure used for compression and heating rate. This paper is devoted to the description and explanation of the effect of the heating rate on the formation of intermetallics during self-propagating high-temperature synthesis in Fe-Al and Ni-Ti systems. Differential thermal analysis of compressed powder mixtures under various heating conditions and microstructure observation of samples prepared by various heating rates using electric resistance heating and spark plasma sintering were carried out. The effect of heating rates on the formations of intermetallics in studied systems is discussed in this paper.

Opis:
Objectives of the research: The aims of this research are to conduct a comparison study between the level of communication and flexibility in families with autistic children in two different geographical locations and cultural contexts – California (USA) and Poland (Europe) – to address whether the level of these two dimensions of family functioning are related to the ego-resiliency of the parents, and additionally to discuss the practical implications that can be drawn from the results. Research methods: Communication and flexibility profiles in family functioning were collected in Poland and California from September 2016 to February 2018. Data on the similarities and differences between parents of children with autism spectrum disorder in Poland (n=111) and California (n=105) was collected using Olson’s FACES-IV. The Ego-Resiliency Scale was also administered in methodologically standardized conditions and was empirically analyzed along with controlled demographic variables. A short description of the context of the issue: Family functioning and ego-resiliency in families with children with autism are analyzed in this research. The richness of interactions and connections within the family system suggests that when explaining the relationships within the family system, the interpretation that is based on linear causality is abandoned and replaced by circular causality, which is the model of analysis utilized in this research project. The main goals of this research were to compare and contrast family functioning in two geographical locations and cultural contexts and to show statistically significant differences between these two groups, in order to better understand cultural variations and differences that may affect family functioning and ego-resiliency and to provide the different groups with adequate, necessary support services. Research findings: The results revealed statistically significant differences in various dimensions of Family Communication and Flexibility between families of autistic children in California and Poland. With respect to both variables, higher scores were found in the California group. The flexibility results in both groups were defined as flexible. However, in regards to family communication, the result of the California group corresponded to higher standardized scores, whereas those of the group from Poland revealed moderate standardized scores. Conclusions and recommendations: Statistically significant positive correlations were found in the variables of Flexibility and Family Communication between Poland and California. The results of this research are critical, not only from the perspective of scientific development (as similar studies have not been conducted), but also for therapeutic and preventive reasons. They suggest concentrating on preventive activities and aspects that are important for the well-being of the parent as a person, as well as the entire family system, especially the dimensions of communication in families with children with autism spectrum disorder and the ego-resiliency of the parents. However, further research is needed to specifically identify the differences between the groups based on various demographic variables. Additionally, it is important to develop a practical model to support families with autistic children and to address family satisfaction in intervention strategies, as well as to consider the importance of support groups that may improve satisfaction and ego-resiliency within the family system.

Opis:
$\text{}^{57}$Fe NMR spectra were measured on thin films of yttrium iron garnet with divalent (Ca$\text{}^{2+}$) and tetravalent (Ge$\text{}^{4+}$) cation substitutions using the spin echo technique at 4.2 K. A series of Y$\text{}_{3-x}$Ca$\text{}_{x}$Fe$\text{}_{5-x}$Ge$\text{}_{x}$O$\text{}_{12}$ samples with 0 ≤ x ≤ 0.0 5 was prepared by an epitaxial growth from BaO/B$\text{}_{2}$O$\text{}_{3}$/BaF$\text{}_{2}$ flux on gadolinium gallium garnet substrate. Satellite lines corresponding to the iron ions having the Ge$\text{}^{4+}$ and Ca$\text{}^{2+}$ in their neighbourhood were identified. The sample with the germanium content of x(Ge) = 0.004 and (110) substrate orientation was used for a detailed study: NMR spectra of this sample were measured in an external magnetic field of 0.1 T applied along several directions in the plane of the film. The modification of the isotropic part and the anisotropy tensor of the hyperfine interaction caused by the Ge$\text{}^{4+}$ substituent were obtained from the experimental data. The results were compared with those previously reported for trivalent substitution (Ga$\text{}^{3+}$).

Opis:
During the last five years we developed method to calculate crystal field and magnetism of rare-earth ions in solids. The method is fully ab initio with the exception of a single parameter which adjust the position of f states relative to other valence states and it was successfully applied in insulating systems. In this contribution the method is used to explain multiplet splitting and magnetism in PrCuAl₃ and NdCuAl₃ intermetallics. For the Nd compound the agreement between theory and experiment is good, while for the PrCuAl₃ the agreement is less satisfactory which can be due to the more delocalized 4f electrons of Pr³⁺ comparing to Nd³⁺ ion.
