Solar-based techniques for water purification in Africa: new technologies for food security

Speaker: Bright Nsolebna Jaato, Dept of Materials Science and Metallurgy, University of Cambridge

According to WHO about 10% of the total burden of disease worldwide could be prevented by improvements in drinking water, sanitation, hygiene and water resource management. Diseases such as diarrhea, which results in 1.5 million deaths each year, and childhood underweight which causes 70,000 deaths yearly, and the transmission of intestinal nematode infections are preventable. This makes the global importance of safe drinking water key for development, poverty reduction and good health.

Bright research looks at how renewable and sustainable technologies for environmental remediation can be developed using materials that less expensive, scalable, and harmless. 

Bright Jaato's areas of research are geared toward providing sustainable solutions to these imminent challenges. These areas include:

• Photo-catalysis
• Photovoltaics
• Energy Storing Devices
• Environmental Remediation

Currently, at the University of Cambridge, my focus is on the synthesis of metal–oxide photo-catalyst materials that are capable of absorbing both UV and visible light for water-splitting (to generate hydrogen fuel) and for water purification.
