Superconductivity phase diagram of NaxCoO2*1.3H2O.
PublicationW pracy przedstawiono wpływ ilości sodu w nowo odkrytym nadprzewodniku NaxCoO2*1.3H2O na właściwości nadprzewodzące. Istnienie obszarów ''underdoped'' i''overdoped'' wskazuje na podobieństwo nowego systemu NaxCoO2 yH2O do wysoko-temperaturowych nadprzewodników tlenkowo - miedziowych.

Bisphenols and their derivatives in baby diaper samples.
PublicationMany common products contain and leach hazardous chemicals, including endocrine-disrupting chemicals such as bisphenols that are harmful to human health. For toddlers, this dangerousness is higher because of their not fully developed detoxification system. Due to this, bisphenols content in products such as baby diapers, should be monitored. Baby diapers not only remain in close contact with the skin, but are also used from the...

Hydration phase diagram for sodium cobalt oxide NaxCoO2*yH2O
PublicationPrzedstawiony został diagram fazowy uwodnionego, sodowo kobaltowego związku tlenkowego Na0.3CoO2*yH2O. Diagram powstał w oparciu o zależność stopnia uwodnienia (y) od wilgotności względnej w temperaturze pokojowej. Zaobserwowano trzy fazy: y = 0, 0.6 i 0.13. Zauważono histerezę przy zamianie kierunku procesu uwadniania.

Implementation of DIFAR Processing in ASW Dipping Sonar
PublicationThis paper presents the implementation of the signal processing algorithm used by buoy DIFAR (Directional Frequency Analysis and Recording), that is fully operational on Polish Navy anti-submarine warfare (ASW) helicopters and ships, applied to dipping sonars for detection and tracking of submarines. The development of the DSP algorithms was a part of the modernization of sonars conducted at the Gdansk University of Technology....

Extended phase diagram of RNiC2 family: Linear scaling of the Peierls temperature
PublicationPhysical properties for the late-lanthanide-based RNiC2 (R = Dy, Ho, Er, and Tm) ternary compounds are reported. All the compounds show antiferromagnetic ground state with the Néel temperature ranging from 3.4 K for HoNiC2 to 8.5 K for ErNiC2. The results of the transport and galvanomagnetic properties confirm a charge density wave state at and above room temperature with transition temperatures TCDW = 284, 335, 366, and 394 K for...
