Miss Xiao-le Liu and Mr. Jian Yang successfully defended their Doctoral and Master theses
On May 26, 2023, Miss Xiao-le Liu and Mr. Jian Yang, supervised by Prof. Zhen Fang, successfully defended their theses at C302 Yuxian Building, Pukou Campus of Nanjing Agricultural University. The defending committee was composed of Prof. Mao-hua Xiao (Chair) from Nanjing Agricultural University, Profs Wei Zhuang and Jun Zhou from Nanjing Tech University as well as Profs Chang-ying Ji, Wei-min Ding and Chun-xia He from Nanjing Agricultural University (NJAU).
Miss Liu and Mr. Yang presented their research results for doctoral and master theses, the committee members raised relevant questions. Based on the replies and theses reviewed, the panels agreed that Miss Liu and Mr. Yang had successfully completed their research and course requirements in agricultural bio-environment and energy engineering. Miss Liu studied the production of microbial lipid from wheat straw with dissertation entitled “Study on mechanochemical pretreatment of wheat straw and enzymatic hydrolysate for microbial lipid production”. She significantly improved the enzymatic hydrolysis efficiency of wheat straw pretreated by solid particle-assisted ball milling pretreatment, and realized the efficient production of lipid from the enzymatic hydrolysis of pretreated wheat straw. Mr. Yang studied biodiesel production of waste cooking oil by bifunctional magnetic catalysts with his thesis entitled "Microwave Assisted Production of Biodiesel from Waste Cooking Oil by Bifunctional SrO-ZnO/MOF Catalyst". Miss Liu published 2 academic papers and Mr. Yang published 1 academic papers. Both of them had all been awarded the title of “Outstanding Graduate of NJAU”. Mr. Yang won President Scholarship of NJAU.
After the juries voted by secret ballot, the panels agreed to confer Doctor of Philosophy in Engineering to Miss Xiao-Le Liu, and Master of Engineering degree to Mr. Yang Jian, subjected to the approval by the Academic Degrees Committees of the college and university.
Miss Liu got a faculty position in Nanjing and Mr. Yang got a job in a state-owned company in Beijing
Congratulations to Miss Liu and Mr. Yang!

刘小乐和杨剑同志顺利通过博士和硕士论文答辩
2023年5月26日上午，南京农业大学生物能源组2019级博士研究生刘小乐（女）和硕士生杨剑（导师方真教授）毕业答辩会在南京农业大学浦口校区育贤楼C302举行。南京农业大学的肖茂华教授担任答辩评审委员会主席，南京工业大学的庄伟教授和周俊教授，南京农业大学的丁为民，姬长英教授和何春霞教授共五位专家担任评审委员。
答辩会上，刘小乐同学和杨剑同学对其在校期间的学术论文进行汇报，同时答辩委员会主席和各位评委提出了相关问题。根据刘小乐同学和杨剑同学的问题回答以及学位论文的评阅，评委会经过评审决议，一致认为刘小乐同学和杨剑同学顺利完成了农业生物环境与能源方面的研究和学习要求。刘小乐同学在毕业论文《机械化学法预处理小麦秸秆及其酶解液发酵产微生物油脂的研究》中研究了球磨和化学颗粒结合预处理小麦秸秆，实现了小麦秸秆的结构解聚，有效提高了小麦秸秆在较低酶载量和较短时间内的酶水解效率，并将水解获得的可发酵性碳源用于发酵产微生物油脂，实现了农作物秸秆到微生物油脂的资源化利用。杨剑同学在毕业论文《双功能SrO-ZnO/MOF催化剂微波辅助餐厨废油制备生物柴油》中研究了利用双功能磁性催化剂催化废油脂制备生物柴油，实现了在较温和条件下一步法催化高酸值废弃油制备生物柴油。刘小乐同学以第一作者身份共发表学术论文2篇，杨剑同学以第一作者发表学术论文1篇，两人均获得2023南京农业大学优秀毕业生称号。杨剑同学获得南京农业大学校长奖学金。
经评委会无记名投票表决，一致同意刘小乐同学通过博士学位论文答辩，建议授予工学博士学位；杨剑同学通过硕士学位论文答辩，建议授予杨剑工学硕士学位。
刘小乐同志获得南京一高校教职，杨剑同学进入北京一国企工作。
祝贺刘小乐和杨剑同学！
