Speech title：Aerospace light-weighting based on carbon nanomaterials use for CO2 emission reduction and neutralization
It is a global agreement that CO2 emission peak and neutralization have to be realized in the middle of this century, which is a complicated and challenging task. The contribution of aerospace and aviation to the global warming has attracted on-going efforts for the reduction of CO2 emissions. One of the most effective ways to reduce fuel consumption and increase energy efficiency is reducing the total mass of aircrafts, as a lower mass requires less lift force and thrust, which is the core concept of aerospace light-weighting. Using ultralight materials to replace heavy metal parts in crafts can effectively reduce the mass and save fuels. In the present, carbon nanotube films and yarns have been developed to meet the requirement and used in the aerospace. This presentation will show the research and development of aerospace products based on carbon nanotube assemblies. These products include shielding layers of signal wires, antenna mesh of satellites, ultrahigh pressure vessels and ultralight wearable heaters and sensors. For instance, when carbon nanotube serves as shielding layers of signal wires, it can reduce the total weight of signal wires by 65%, which is high of significance in reducing the fuel consumption and in conserving the CO2 emission.
Dr. Xin graduated from University of California, Los Angeles (UCLA) in March 2016, majored in materials science and engineering. After graduation, Dr. Xin was employed as the Staff Research Associate at UCLA from 04/2016 to 04/2017. During this period, his research mainly focuses on the multifunctional carbon nanomaterials, including (1) growth of anisotropic gold nanostructures on graphene and CNT support (2) in-situ high-resolution TEM characterization of carbon and metal interfaces (3) flexible SERS sensors based on carbon nanomaterials.
Then Dr. Xin was offered the position of Senior Research Scientist at Craytex LLC from 05/2017 to 05/2020, to investigate aerospace applications of CNT films and yarns. His work mainly includes (1) enhancement of the mechanical and electrical properties of carbon nanotube sheets and yarns and (2) development of aerospace products based on CNT films and yarns.
In July 2020, Dr. Xin moved to China and has been appointed as Professor at the College of Materials Science and Engineering, Nanjing Tech University
Dr. Xin has a published a series of papers in the high-profile journals such as Nano Letters, ACS Applied Materials and Interfaces, Composite Part B-Engineering, Nanoscale, Chemical Communications, Journal of Physical Chemistry C, etc. He is now the guest editor of Nanomaterials and serve as an invited reviewer for ACS Applied Materials & Interfaces, ACS Applied Electronic Materials, Advanced Materials Interfaces, Materials Letters, RSC Advances etc.
