1、报告题目：Waste Lignin towards the Future of Healthcare（凯聃博士）
内容摘要：
Lignin has always been considered as waste from paper industry and it has been utilized in low-value applications, including heat and electricity generation. But, it is the second most abundant biopolymer on earth, which could potentially resolve the issue on rapidly depleting resources. Scientists have made extensive efforts to translate waste lignin into a renewable source or even precursor to higher value materials. The advanced chemical modification has been considered a useful method to valorize lignin. A number of functional lignin-based polymers integrated with both the intrinsic features of lignin and additional properties of the grafted polymers have been synthesized. In our study, various lignin-based grafted copolymers were synthesized by atom transfer radical polymerization (ATRP) or ring-opening polymerization (ROP). The chemical structures, molecular weight, thermal and mechanical properties of such lignin copolymers were investigated. There lignin copolymers showed tunable molecular weights and thermal properties. These modified lignin and its copolymers displayed better compatibility with other polymeric matrix, which improved the performance and physicochemical properties of the lignin composites. Moreover, such lignin copolymers were developed into value-added functional materials, including hydrogels, creams, nanofibers and gene vectors. With excellent antioxidant activities and good biocompatibility, these lignin-based functional materials hold great potential to be used as advanced materials for healthcare applications.

2、报告题目：Paper Electronic Devices（徐雪珠博士）
内容摘要：
Paper is used as a substrate for various types of flexible electronic devices including displays, sensors, transistors, RF devices, generators and light-emitting diodes. It has been developed into a new discipline called paper-based electronics. Due to the advantages of good flexibility, light weight, low cost, environmental friendliness and reusability, paper-based materials are a very promising material. Nowadays, nanocellulose has become a major role in developing paper-based electronics. This report includes how to expand the application of nanocellulose in aerogel and heat-resistant carbon materials, how to use TEMPO-salt solution to disperse carbon nanomaterials, how to use TEMPO oxidation to extract nanocellulose and convert it into gas sensing devices, how to use cellulose nanocrystals to regulate the optical properties of paper and prepare paper-based LED light emitting devices. Although nanocellulose has unique advantages in the preparation of flexible paper-based electronic device structures. there are still some disadvantages limiting the development of nanocellulose in paper electronics, i.e., few types of nanocellulose, monotonous surface charges, high hydrophilicity and paper is easily torn and curled. The report also describes the future research difficulties and outlooks how to advance the development of paper-based electronic devices.
