This study investigated the influence of site conditions on physical and morphological properties hawthorn (Crataegus azarolus L.) wood grown in Zagros forests Iran. Hawthorn is a valuable woody species Iran’s with data deficiency its properties. To our best knowledge, there no wood. Twenty-seven mature trees were randomly chosen sampled at three altitude levels (1 800–2 000, 2 000–2 200, 200–2...

Dual atom catalysts (DACs) not only retain uniform active sites and high atomic utilization efficiency as the single catalysts, but two adjacent metal also cooperate play a synergistic role to achieve additional benefits. However, relationships connecting their dual-site effects on catalytic performance are well rationalized due limited pairs available from experiments. Herein, Fe/M dual suppor...
