NT for Climate Change

Climate change is an urgent global problem that must be addressed and that requires immediate attention. Carbon dioxide emissions appear to be a direct cause of climate change due to the major global dependence on fossil fuels for transportation and electricity production, but the impact of climate change goes far beyond climate itself, as it can cause energy crises as well as water and food shortages. Unfortunately, the reduction of carbon emissions alone cannot solve the global problems caused by climate change. Thus, for a timely and proper response, many disciplines must work together without boundaries. The development of advanced membranes for water desalination and the realization of viable methods to reduce carbon dioxide based on NT must be next-generation solutions for these problems.
 

 

Research Topics

 

Nanotechnology for Water and Solar Energy

Conventional water desalination technologies such as reverse osmosis requires significant energy consumption, prompting a pressing need for new materials and systems that are energy-efficient and sustainable, for which nanotechnology (NT) plays a core role. In NT for Climate Change, we are also actively developing innovative materials for the high efficiency solar cell technologies as part of sustainable future energy sources.
 

Nanotechnology for Advanced Battery

Nanomaterials and their assembly can incorporate future active materials into rechargeable batteries. Once smart nanomaterial designs are integrated, in particular, high capacity materials, such as silicon, lithium, and sulfur can increase the energy densities of batteries significantly so that they can play a key role in extending driving mileage of electric vehicles. Nanomaterials can also be adopted for flexible and wearable batteries that will play as power sources of various future wearable IT devices.
 

Efficient Processes for CO2 Capture & Conversion

The concentration of atmospheric CO2 reached 400 ppm at 2015 due to continuous increase in global energy demand, causing unexpected climate change. Therefore, the capture, conversion and utilization of undesired CO2 is the most important issue confronting global warming. Nanotechnology breakthrough provides opportunities to develop efficient CO2 capture and conversion system using solar and electrical energy where innovative ideas would bring the possibility to tackle climate change.
