An EXAFS study of the local structure of rare-earth luminescence centres in the Ca3Ga2Ge3O12 glass
PublicationW pracy przedstawiono wyniki analizy EXAFS danych mierzonych na krawędzi L3 atomów ziem rzadkich takich jak Eu, Ho (0.7 wt.%) oraz Er (1.46 wt.%), którymi domieszkowano szkło 3CaO-Ga2O3-3GeO2. Otrzymane parametry strukturalne opisujące pierwszą powłokę koordynacyjną badanych atomów wskazują, że ich lokalne otoczenie tlenkowe jest jednakowe (niezależne od typu jonu ziemi rzadkiej) i uwzględniając strukturalny nieporządek bardzo...

A XAS study of a highly diluted Pt electrocatalyst operating in PEM fuel cells
PublicationWe present an X-ray absorption spectroscopy (XAS) study of a low Pt content catalyst layer(Pt loading 0.1 mg c2) operating at the cathode of a proton exchange membrane fuel cell(PEMFC). This catalyst is based on the use of a mesoporous inorganic matrix as a support forthe catalyst Pt nanoparticles. Due to the high Pt dilution, in situ measurements of itsstructural properties by XAS are challenging and suitable experimental strategies...

Study of the formation of calcareous deposits on cathodically protected steel in Baltic sea water
PublicationPurpose – The purpose of this paper is to investigate whether the sedimentation of calcareous deposits occurs on cathodically protected steel in Baltic sea water. Design/methodology/approach – Steel electrodes were cathodically polarized in natural Baltic sea water at potential þ0.150 V vs Zn electrode in potentiostatic mode. During exposure chronoamperometric measurements were carried out. After the exposure, the electrode’s surface...

Study of Soil Temperature and Moisture Changes in a Physical Model of an Underground Cable Line
PublicationThe ampacity of power cables is highly dependent on the thermal resistivity of the soil in which they are laid. The lower it is, the higher this ampacity. The thermal resistivity of the soil decreases as its moisture increases. Therefore, it is preferable that the soil around the cables has high moisture. Unfortunately, the heat generated in heavily loaded cables causes the migration of moisture from the surrounding soil, which...
