Extending a Battery's Lifetime with Heat


The research of alumnus Asghar Aryanfar (’15 PhD, ME) along with Professors Goddard and Hoffmann has shown that heat can break down the damaging branch-like structures that grow inside batteries, which may possibly be used to extend battery lifetimes. [Learn more] [Read the paper]

121st Commencement Ceremony


Caltech’s 121st commencement ceremony was held on Friday June 12, 2015. The commencement speaker was cultural anthropologist Genevieve Bell, an expert on the intersection of culture and technology. She reminded the graduates that it is the 50th anniversary of Moore’s Law which she referred to as a bold statement of engineering and a promise about the state of the future. She asked the graduates to not only bring their technical skills to the table, but also their humanity and obligation to make the work a better place. [View Dr. Bell’s commencement address]

A Winning Sanitation Solution


The inventors of the solar-powered toilet, a unit developed by a team led by Professor Michael Hoffmann, have a new award winning project. Project Seva, which means "service" in Hindi. It was named the first place winner of the Vodafone's Wireless Innovation program. The Seva team realized that because the solar toilet and other sanitation systems like it are relatively simple, inexpensive sensors could be used to monitor the status of those systems' parts. Combining that insight with the knowledge that more than three-quarters of the world's people have access to a mobile phone, the team decided to design a self-diagnosing maintenance system for sanitation solutions that could alert designated local operators of a malfunction via cell phone message.

Tracking Photosynthesis from Space


Professor Paul Wennberg and colleagues have developed a new technique to analyze plant productivity using data from NASA's Orbiting Carbon Observatory-2 (OCO-2) satellite. To perform photosynthesis, the chlorophyll in leaves absorbs sunlight and a small fraction of the absorbed light is reemitted as near-infrared light. This reemitted light makes the plants appear to glow—a property called solar induced fluorescence (SIF). "The measurements of SIF from OCO-2 greatly extend the science of this mission", says Professor Wennberg. "OCO-2 was designed to map carbon dioxide, and scientists plan to use these measurements to determine the underlying sources and sinks of this important gas. The new SIF measurements will allow us to diagnose the efficiency of the plants—a key component of the sinks of carbon dioxide." [Caltech story]

Women Making History


In celebration of Women’s History Month, influential women leaders from the Jet Propulsion Laboratory (JPL) and Caltech gathered at the JPL von Karman auditorium. Present at the event, entitled Women Making History, were the 2015 honorees for Women@JPL as well as Caltech faculty and staff. It was an opportunity for women at different stages of their career to meet and network. EAS faculty were represented by Professors Bordoni, Greer, and Hunt.  The JPL Advisory Council for Women was the lead organizer of the event.

Professor Bordoni Receives Young Investigator Award in Environmental Sciences


Simona Bordoni, Assistant Professor of Environmental Science and Engineering, has received a Young Investigator Award in Environmental Sciences from the Italian Scientists and Scholars in North America Foundation (ISSNAF). The award is given to early stage investigators working in North America whose commitment to their discipline of study is innovative, impactful, and honors their country of origin. Professor Bordoni received the award for her research in fundamental monsoon dynamics, specifically aquaplanet monsoons and their response to climate changes. She has also received a medal from the President of the Italian Republic, "Medaglia di Rappresentanza del Presidente della Repubblica Italiana." [Research abstract]
