Irradiation effects on thin foils of bulk YBa, Cu, 0, _ x have been studied in a transmission electron microscope using lOO-, 150-, 200-, 250-, and 300-keV electrons at 83 and 300 K. The disordering of the oxygen atoms and vacancies in the O(4) and 0( 5) sites in the Cu-0 planes during irradiation was monitored by measuring the splitting of the (li0) diffraction spots in the [OOl ] diffraction ...

Chromated copper arsenate-treated (cca) wood disposal faces environmental restrictions due to its toxicity, heavy metal leaching in storage sites, and greenhouse gas emissions during incineration. Thus, finding new management methods for this contaminated at the end of life is crucial. This study evaluated effect pyrolysis temperature (300, 400, 500 °C), particle size, biochar yield, behavior a...
