Multistep energy migration between 3,3'-diethyl-9-methylthiacarbocyanine iodide monomers in uniaxially oriented polymer films
PublicationWykonano pomiary obserwabli fluorescencyjnych dla wieloetapowego transferu energii w układzie zawierającym MDTCI (3,3'-diethyl-9-methylthiacarbocyanine iodide) w rozciąganych osiowo foliach polimerowych (PVA). Wyniki doświadczalne porównano z rezultatami symulacji Monte Carlo, stwierdzając ich bardzo dobrą zgodność. Ponadto z symulacji Monte Carlo otrzymano szereg informacji nie dających się zmierzyć doświadczalnie jak np. czas...

Electric field effect on luminescence, and photoconduction in electron donor - electron acceptor organic solid films
PublicationZaobserwowano silne wygaszenie fotoluminescencji (80%) i duże fotoprądy (1mA/cm2) w układzie dendrymer aminowy m-MTDATA (donor elektronu) : pochodna fenantroliny BPT (akceptor elektronu) niedomieszkowanym oraz zawierającym domieszkę w postaci organicznego kompleksu platyny PtL2Cl. W interpretacji wyników uwzględniono elektrycznopolową dysocjację singletowych ekscypleksów m-MTDATA:BPT i trypletowych ekscypleksów m-MTDATA : PtL2Cl...

Vibrational excitation of tetrahydrofuran by electron impact in the low energy range
PublicationWzbudzenie oscylacyjne cząsteczki tetrahydrofuranu w zderzeniach z elektronami przeprowadzone było w zakresie energii 5-14 eV w szerokim kącie rozproszenia (20°-180°). Pomiary funkcji wzbudzenia oscylacyjnego modów rozciągających w grupie CH2 (wiązania C-H) wykazują obecność struktur dla energii 6.0, 7.9 i 10.3 eV, którym można przypisać formowanie się stanów rezonansowych jonów ujemnych cząsteczki. W pracy wyznaczono także różniczkowy...

Single-dopant organic white electrophosphorescent diodes with very high efficiency and its reduced current density roll-off
PublicationW pracy opisano konstrukcję wysokowydajnej diody elektrofosforescencyjnej zawierającej domieszkę organicznego kompleksu platyny PtL2Cl (L oznacza organiczny ligand). Dioda emituje światło białe które pochodzi od ekscymerów świecących w czerwieni i wzbudzonych monomerów świecących w części niebieskiej widma. Kwantowa wydajność świecenia diody wynosi ok. 15% i słabo maleje ze wzrostem gęstości płynącego prądu elektrycznego.

Physical properties of the noncentrosymmetric superconductor Mg10Ir19B16
PublicationPrzedstawione zostały wyniki pomiarów ciepła właściwego, oporu elektrycznego i podatności magnetycznej nowo odkrytego materiału nadprzewodzącego Mg10Ir19B16. Na podstawie pomiarów ustalono, że Mg10Ir19B16 jest nadprzewodnikiem drugiego typu (kappa=20), ze stałą sprzężenia elektron - fonon lambda_ep=0.66.

Attitudes of Polish physicians, nurses and pharmacists towards the ethical and legal aspects of the conscience clause
PublicationBackground: While healthcare professionals’ right to invoke the conscience clause has been recognised as a fundamental human right, it continues to provoke a heated debate in Polish society. Although public discourse is filled with ethical and legal considerations on the conscience clause, much less is known about the attitudes of healthcare professionals regarding that matter. The aim of this study was therefore...

To donate or not to donate? Future healthcare professionals’ opinions on biobanking of human biological material for research purposes
PublicationBackground Over the last few decades biobanks have been recognised as institutions that may revolutionisebiomedical research and the development of personalised medicine. Poland, however, still lacks clear regulationsregarding the running of biobanks and the conducting of biomedical research. While the awareness of the generalpublic regarding biobanks is low, healthcare professions and medical students also...
