  The Ge0.77Ag0.1Sb0.13Te1alloy was fabricated by a novel two step route. For that purpose firstly the oxide reagents were melted at high temperature and quenched into pellets. After that pellets were milled to the powder and then reduced in hydrogen at various temperatures and for various periods of time. Energy dispersive X-ray analysis indicated the possibility of successful fabrication of stoichiometric thermoelectric materials...

  Volatile fraction of fruits is a rich source of bioactive and aroma compounds, which can be used in the cosmetics industry after meeting relevant criteria. This is particularly evident in citrus fruits, especially in Citrus hystrix, in which the headspace consists mainly of terpenes. Due to the insufficient sensitivity of analytical methods, essential oils are used in investigations in contrast to fresh fruits. Therefore, a novel...

  This study investigated the influence of the amount of steel and copper fibres in a train brake friction material on the tribological performance, emission intensity and characteristics of airborne wear particles. The particles were generated on a pin-on-disc tribometer under controlled friction and environmental conditions. It was found that the steel fibre results in a more intensive emission of 0.3–10 μm particles compared to...

  W materiale o składzie (Bi,Pb)-Sr-Ca-Cu-O wskutek stosowania różnych warunków wytwarzania można otrzymać materiały o różnorodnych właściwościach. W efekcie wygrzewania materiał amorficzny częściowo krystalizuje. To powoduje wzrost rozmiaru i zawartości przewodzących i nadprzewodzących granul oraz zmniejszenie szerokości izolujących barier pomiędzy granulami. Zależność temperaturowa oporu słabo skrystalizowanego materiału jest funkcją...
