Photosynthesis Discovery Could Lead to Design of More Efficient Artificial Solar Cells

A natural process that occurs during photosynthesis could lead to the design of more efficient artificial solar cells, according to researchers at Georgia State University.During photosynthesis, plants and other organisms, such as algae and cyanobacteria, convert solar energy into chemical energy that can later be used as fuel for activities. In plants, light energy from the sun causes an electron to rapidly move across the cell membrane. In artificial solar cells, the electron often returns to its starting point and the captured solar energy is lost. In plants, the electron virtually never returns to its starting point, and this is why solar energy capture in plants is so efficient. A process called inverted-region electron transfer could contribute to inhibiting this “back electron transfer.”

Georgia State Study Uses Social Media, Internet To Forecast Disease Outbreaks

and has no comments yet.
When epidemiological data are scarce, social media and Internet reports can be reliable tools for forecasting infectious disease outbreaks, according to a study led by an expert in the School of Public Health at Georgia State University.“Our study offers proof of concept that publicly available online reports released in real-time by ministries of health, local surveillance systems, the World Health Organization and authoritative media outlets are useful to identify key information on exposure and transmission patterns during epidemic emergencies,” the researchers said. “Our Internet-based findings on exposure patterns are in good agreement with those derived from traditional epidemiological surveillance data, which can be available after considerable delays.”
