LaB6 has been used as a commercial electron emitter for decades. Despite the large number of studies on work function LaB6, there is no comprehensive understanding trends in hexaboride material family. In this study, we use density functional theory calculations to calculate rare-earth and rationalize these based electronegativity metal element. We predict that alloying with Ba can further lowe...

this work deals with the calculation of franck-condon factors using hua potential function for the first time. the advantages of this function have been mentioned, and the numerical methods are used to obtain franck-condon factors for the following band systems: agreement between the values of this work and those obtained from other works is quite good that verifies the reliability of the prese...

heat stress effects on physical and mental health of workers and decreases human function. asphalt workers are both exposed to the heat of their working process and to the sun heat. this study aimed at evaluating thermal stress and its following function fall and the effect of asphalt work on the degree of heat stress and asphalt workers’ physiological parameters. the present study was done at ...
