Morphology of polyurethanes revisited by complementary AFM and TEM
PublicationPrzedmiotem badań mikroskopowych TEM i AFM były lane segmentowe poliuretany o zawartości 30 i 50% segmentu sztywnego. Stwierdzono obecność sferolitów (poziom mikrometrów), fibryl i globul. Ponadto zastosowanie AFM pozwoliło na zbadanie nanomorfologii badanych poliuretanów. Zaobserwowano krótkie, cylindropodobne domeny segmentów sztywnych rozproszone w matrycy segmentów giętkich.

TEM and AFM studies of segmented polyester polyurethanes obtained by quasi-prepolymer method.
PublicationPrzedmiotem badań były poliestrouretany o zawartości 50% segmentów sztywnych i zmiennym stosunku NCO/OH. Wykazano, że poliestrouretany otrzymane metodą quasi-prepolimerową wykazują inną morfologię niż otrzymane za pomocą metody prepolimerowej. W poliuretanach quasi- prepolimerowych obserwowano za pomocą mikroskopu AFM agregację segmentów sztywnych o wymiarze poprzecznym rzędu200nm. Segmenty te tworzyły fazę ciągłą. Kruche...

The effect of depth of surface layers constituted by vacuum technologies on pitting
PublicationThe paper presents the results of a study of the effect of vacuum technologies of formation of surface layers on pitting of associated elements in a lubricated, heavy-load rolling contact. The study has shown that increase in a PVD coat depth is accompanied by decrease in the fatigue friction pair.

Empirical Analysis of Forest Penalizing Attribute and Its Enhanced Variations for Android Malware Detection
PublicationAs a result of the rapid advancement of mobile and internet technology, a plethora of new mobile security risks has recently emerged. Many techniques have been developed to address the risks associated with Android malware. The most extensively used method for identifying Android malware is signature-based detection. The drawback of this method, however, is that it is unable to detect unknown malware. As a consequence of this problem,...

Triplet Formation and Triplet‐Triplet Annihilation Upconversion in Iodine Substituted Non‐Orthogonal BODIPY‐Perylene Dyads
PublicationBODIPY-perylene dyads have emerged as useful metal free sensitizers for triplet-triplet annihilation upconversion (TTAUC), these dyads are capable of efficient triplet generation via spinorbit charge transfer intersystem crossing (SOCT-ISC). This important route to triplet formation requires dyads in which two moieties are oriented perpendicular to each other. In this contribution, we give a deeper insight on the behavior of recently...

Dissociative electron attachment to the radiosensitizing chemotherapeutic agent hydroxyurea
PublicationDissociative electron attachment to hydroxyurea was studied in the gas phase for electron energies ranging from zero to 9 eV in order to probe its radiosensitizing capabilities. The experiments were carried out using a hemispherical electron monochromator coupled with a quadrupole mass spectrometer. Diversified fragmentation of hydroxyurea was observed upon low energy electron attachment and here we highlight the major dissociation...
