Join us on Friday, May 3rd at 11am for another installment of our Spring Chemistry Seminar series! Guest lecturer, Dr. Dongmei Dong, will be joining us from Rowan University!

 

Abstract:

 

Even though the natural cycle of climate change is an ongoing and unavoidable step of life, history seems to be telling us that when past civilizations have overstretched themselves or pushed their consumption of natural resources to the brink, the consequence of climate change soon became amplified. We are now in a critical period with challenges and opportunities to address climate change by developing environmentally responsible and sustainable energy technologies. Up to 40% of the primary energy loss worldwide is currently in buildings for lighting, heating, ventilation, and air conditioning (HVAC). The awareness of being environmentally friendly and carbon dioxide emission issues are driving the rapid development of electrochromic (EC) materials and associated devices today, especially regarding the implementation of windows or glazing for energy-efficient architectures and buildings. Recently, EC supercapacitors are growing as a promising category of devices in the rising deployment of portable electronics, optoelectronics, displays, etc. EC energy storage has attracted more and more attention in the decade. In addition to their charge storage applications, they can directly tune the relations between humans and sunlight based on their adjustable and reversible optical properties, reducing energy consumption by about 20% in buildings for “smart window glazing” applications. The efficient energy storage and derivation enables the green energy cycles and has a broad range of applications in powering lights, LEDs, and portable electronic devices. The visual energy status brings a lot of convenience to modern life. Consistent with most renewable energy systems (fuel cells, photovoltaic cells, batteries, solar fuel generators, etc.) in terms of common electrochemical origins, constrained by thermodynamics but further reduced by kinetics. Improving the kinetics imposed by reality relies on the fundamental de-coding at the nano and atomic level with a comprehensive analysis that crosses multiple disciplines.
