Speech Title: Collagen Derived Advanced Materials for Energy and Environmental Applications
Abstract: Collagen, the most abundant protein on earth, is a fibrous structural protein with intriguing mechanical properties namely high viscoelasticity and large fracture strength. It plays a crucial role in making Nature’s structural materials tough. It is being processed in a variety of industries such as slaughterhouse, meatpacking, leather and related. Nevertheless, these industries generate significant amount of collagen containing co-products (bio-wastes), which can be used as a precursor for the bulk synthesis of nanomaterials and nanocomposites for high-value applications. The talk will feature novel ways of converting these collagen co-products into a range of advanced multifunctional materials such as self-doped carbon nanomaterials, Cr@C / Fe@C core-shell nanomaterials, N-rich carbon nanoonions, magnetic and conducting nanobiocomposites for energy and environmental remediation applications. The proposed new avenues for converting industrial bio-wastes into useful multifunctional advanced materials based on nanoscience approach are scalable and inexpensive thereby minimizing pollution and maximizing environmental sustainability.

Speech Title: The Role of Human Nature in the Energy Revolution
Abstract: In order to achieve the goal of carbon emission reduction, the work on energy sector is mainly through two paths – 1) Renewable energy alternatives; 2) Increasing energy efficiency. This article has mainly analyzed the negative reactions from different sectors of the energy industry in facing the challenge of energy revolution, and Point out that those are the natural reflection of human nature. The energy policies and institutions are critical on the prospect of energy revolution, which should the premise of guaranteeing people's basic needs, we should try our best to stimulate the positive energy in human nature. Meantime, we need high technologies like AI, to provide customers with the best possible service, and overcome management bottlenecks and create new job prospects.

Speech Title: Key technology of high precision real-time monitoring and control in the distribution network（配电网故障高精度实时监控关键技术）
Abstract: The non-effective neutral grounding mode is adopted in most of the medium-voltage distribution networks in China.The fault in distribution network is with the characteristics of instantaneity and weakness. The fault resistance is usually up to a few kilo-ohm, even dozens of kilo-ohm. After a long-time arc combustion, only the fault less than the 1kΩ is detected and delt with the relay protection. However, there exsits hidden danger in such long-time faulty distribution network. It may trigger the different accidents, such as electric shock, equipment burnout, transformer substation damage and so on. In all, the high precision real-time monitor of the distribution network is a difficult technical issue over a long period.
(1) Aiming at the technical difficulty of fault transient signal real measurement under strong electromagnetic environment in distribution network, the fault signal real measurement theory is established. The sensitive and reliable fault transient signal transfer method under strong electromagnetic interference is proposed, and the wide-area real synchronous measurement of weak signal in distribution network is realized.
(2) Aiming at the technical difficulty of the initial fault detection and accurate fault location under the high impedance and arc fault condition, the fault identification and location method based on wide band panoramic information is proposed. It realizes the the accurate fault location in complex distribution network and there are the errors less than 100m.
(3) Aiming at the fact that the distribution automation equipment exists diversity, field access difficulty, massive data real-time processing difficulty and the low equipment availability, the cloud-edge-terminal three-tier distribution network security operation management mode based on power internet of things is constructed. It realizes the real-time efficient monitor of distribution network and promotes effectively the safety operation of distribution network.
It has promoted significantly the scientific and technological progress in the field of distribution network safety monitoring, which is significant in reducing the hidden danger of personal equipment, reducing power outage, improving the utilization rate of equipment and improving the quality of people's production and life.
