On August 20 morning, Tang Tian-gang and Wu Zhao-cheng did their PhD and MSc degree viva, respectively. Tiangang worked on compound-specific radiocarbon and stable carbon and deuterium isotopes of IVOCs/naphthalene. Zhaocheng worked on leaching of PFAs in soil columns with and without plants. Both of them succeeded in the viva. The video viva was organized online. Congratulations!
