Degradation of ferritic X10CrAlSi18 stainless steel caused by slurry
PublikacjaThe slurry erosion tests of ferritic X10CrAlSi18 steel were carried out using a slurry pot device. In order to investigate the erosion process, two series of tests were performed: first one with a constant impact velocity of 5 m/s, 7 m/s and 9 m/s and the second one, during which the impact velocity was changed after every exposure. During each test, an influence of test conditions on volume loss, surface hardness and roughness...

Ex-situ XRD (X-ray Diffraction) results for electrodes under different charge/discharge states
Dane BadawczeEx-situ XRD was employed to analyze the energy storage mechanism of CPMD in ZICs system. The ZICs were firstly charged to 1.8 V from the open circuit voltage (at around 1.3 V), then discharge to 1.0 V and 0.2 V, and finally recharged to 1.0 V and 1.8 V. Sample abbreviations (CPMD) are in agreement with the markings used in the linked publication.

Precypitacja węglanu wapnia metodą karbonatyzacji z dodatkiem glicerolu w obecności wybranych promotorów absorpcji CO2
PublikacjaJednym ze sposobów produkcji węglanu wapnia jest metoda gaz-ciecz, w której jako reagent stosuje się gazowy CO2 oraz roztwór soli wapnia, do którego dodawane są związki sprzyjające absorpcji CO2, tzw. promotory. Reakcja z gazowym CO2 jest specyficzna, ponieważ powstawanie jonów wodorowęglanowych podczas absorpcji CO2 z reakcją chemiczną jest etapem decydującym o szybkości procesu strącania CaCO3. Celem niniejszej pracy było określenie...
