9:30 am: Noah Stern, Water + Carbon + Environment. Followed by Q/A
The Water and Carbon cycles are arguably the most important cycles for humankind to understand. The water cycle is the largest cycle on the planet, and the carbon cycle is at the heart of the threat of climate change. Current models of sediment carbon dynamics focus on preservation of organic carbon through formation of carbon-mineral aggregates. However, the preservation of carbon in these soil aggregates depends on their stability. My research focuses on the importance of particulate organic carbon in the development of microbial hot-spots where highly elevated release rates of CO2 and CH4 occur. Connecting the contribution of particulate organic carbon to the freshwater carbon cycle has large implications for natural and engineered environments.

SMART sensor just won the DOE’s JUMP award!
Responding to the call from BUILDING ROBOTICS and Berkeley lab, our SMART sensor entered the challenge to build ‘MEAN RADIANT TEMPERATURE SENSING FOR IMPROVED THERMAL COMFORT’ in July, 2016 and just won the $3000 cash price and now enters the pool to participate DOE Lab Impact Small Business Vouchers (SBV) Pilot Small Business Voucher to request $300k of in-kind technical support for prototype development, testing and other problem statements facing small businesses in the clean energy innovation space.
More about the call can be found on the JUMP website.

Meggers won Eric and Wendy Schmidt Transformative Technology Fund for pressurized air tank that captures full-scale fluid dynamics behavior as full-scale wind tunnels!
Enhancing wind power
A new apparatus will help researchers develop wind turbine designs without building full-scale prototypes. Given the massive size of today’s turbines, building test models at full size is not feasible, yet scaling down these models causes inaccurate predictions of their capabilities. However, it is possible to reproduce the full-scale dynamics by placing the scaled-down models inside a container of highly pressurized air.
A team composed of Marcus Hultmark, assistant professor of mechanical and aerospace engineering, Forrest Meggers, assistant professor of architecture and the Andlinger Center for Energy and the Environment, and Elie Bou-Zeid, associate professor of civil and environmental engineering, will build a test facility that uses a pressurized air tank and can accurately capture the physics of full-scale turbines. The apparatus will be housed on Princeton’s nearby Forrestal Campus.
“The Eric and Wendy Schmidt Transformative Technology Fund gives Princeton the capacity to invest in truly innovative and highly promising research — research that is often considered too forward-looking for traditional funding mechanisms,” said Dean for Research Pablo Debenedetti, the Class of 1950 Professor in Engineering and Applied Science and professor of chemical and biological engineering. “This year’s selected proposals are outstanding in terms of the quality of the science and engineering as well the potential to benefit humanity through practical benefits to human health and the environment.”
