Chemistry of Energy and Food

Daniel Nocera, Artificial leaf

The artificial leaf accomplishes the energy storage process of photosynthesis and does so with earth-abundant materials, no wires, and direct solar-to fuels process. Two earth abundant catalysts have been discovered that promote the oxygen evolving reaction (OER) and hydrogen evolving reaction (HER). The ability to operate these catalysts under benign conditions (in water at pH 7 and under 1 atm) has enabled the construction of the artificial leaf, which consists of a silicon wafer, coated with the respective OER and HER catalysts. By immersing the artificial leaf in water and holding it up to sunlight causes efficient water splitting; and all of this is done with no wires or membrane. By constructing a simple, stand-alone device composed of earth-abundant materials, the artificial leaf provides a means for an inexpensive and distributed direct solar-to-fuels conversion process with low-cost systems engineering and manufacturing requirements. The science behind the catalysts and the artificial leaf will be presented.

Chemistry of Energy and Food

John Floros, Feeding the world through science and technology: A look into our future food system

Scientific and technological developments over the last century transformed our food system into a global, enormously complex, and extremely sophisticated system that has successfully achieved a safe, nutritious, abundant, and sustainable food supply for healthier people everywhere. Nevertheless, projected increases in human population, greater urbanization and an improved diet indicate that current food production levels must be raised substantially, and processing methods must be improved significantly over the next few decades. In addition, our food system faces other serious challenges, including environmental changes, water pollution and shortage, soil erosion and nutrient depletion, energy availability and price, limited food accessibility and malnutrition, over-consumption and obesity, longer human lifespan and an aging population, food safety concerns, and threats from terrorism. We will briefly review these challenges and look into the future, when food scientists and technologists will work closely with chemists, biochemists, animal scientists, agronomists, horticulturists, molecular biologists, toxicologists, materials scientists, nanotechnologists, bioengineers, and other experts in informatics, nutrigenomics, medicine and health sciences to improve the food system and make life better for everyone.

 
 
Cesar Vega, Kitchen as laboratory: Building bridges between science and the non-scientist

It is no secret that communicating science to the general public is a challenge. And, it should be no secret that to do this effectively provides the non-scientist with a more realistic perspective of the reaches and limitations of science, and in a better position to interpret and even apply scientific information. However, it seems that we have plenty of homework to do ahead of us. First consider that for the most part, the audience we aim to reach has less technical/scientific knowledge and second, that it is others, (i.e. the media) who take the lead on translating our findings – not always accurately. Inaccurate science interpretation results in misinformation and confusion among the lay public which then minimizes the ability to make informed decision based on science. Is there something we can do to improve the quality of the message? Absolutely. I will try to make a case for the above through food.Food is personal…and complex. Cooking makes food even more personal and brings up further complexity through the transformations and interactions that it promotes. I'm sure that most of your non-scientist friends wonder why using cream of tartar makes better meringues, do you? Cooking is a great tool to demonstrate scientific principles and science offers an exciting path into the kitchen. The challenge is in making the bridge, allowing others to cross it from both sides. I will provide a few examples of bridges that others and I have built.

Empowering Equal Access for Persons with Disabilities in the Chemical Profession

Division of Professional Relations

Shannon Watt, OXIDE: Empowering equal access for academic chemists with disabilities
Closed Captioned, Transcript

The Open Chemistry Collaborative in Diversity Equity (OXIDE) was founded in 2011 to sustain and expand upon the national conversation begun through a series of academic equity workshops—including one on disabilities—sponsored by the National Science Foundation, the National Institutes of Health, and the Department of Energy from 2006-2009. OXIDE serves as a bridge between the chairs of leading doctoral-granting chemistry departments, representatives from diversity communities, and social scientists with diversity-related expertise, with the aim of reducing inequities that have historically contributed to the mismatch between the gender, race-ethnicity, sexual orientation, and disability demographics of chemistry faculty and the nation as a whole. This presentation will summarize several initiatives that preceded OXIDE and share our current approaches to discussing congenital, acquired, visible, and hidden disabilities with department chairs. It will also allow the OXIDE team to learn from symposium participants about additional strategies for gathering data and promoting policies and practices that empower equal access for chemists with disabilities.

 
 
Roger Tower, Using summer STEM enrichment programs to inspire and engage students with blindness or low vision (BLV) in chemistry curriculum
Closed Captioned, Transcript

To fully engage a student in academic material, the topic must be applicable and relevant to the experiences one will encounter outside the classroom. In this presentation Roger Tower, will discuss his implementation and design of chemistry and other science curricula to campers at the Enchanted Hills Summer Camp (EHC) for the Blind in Napa Valley, CA. In partnership with the San Francisco Lighthouse for the Blind, EHC empowers individuals to find strength, confidence and independence while enjoying nature, making friends, and meeting other people with disabilities. Using the accessible Talking LabQuest, campers GPS tracked experiments throughout the camp and tested water quality, humidity, temperature and hand-grip strength. For many, this was the first chance to independently collect and analyze data in the field. Come learn how vital summer camp experiences can be for students with and without disabilities.

 
 
Annemarie Ross, Empowerment of deaf and hard-of-hearing scientists through education, accommodations, and inspiration
Closed Captioned, Transcript

As deaf and hard-of-hearing individuals empower themselves through access to educational and professional accommodations, they can also become inspired by the successes of past and contemporary role models. Successful deaf and hard-of-hearing scientists include those who have won the Nobel Prize, popularized scientific poster sessions by using supplemental visual material, and discovered elements on the periodic table. The characteristics of these role models and accommodations used to support deaf and hard-of-hearing scientists will be discussed in an effort to show how beneficial role models and accommodations can be. Information about the Laboratory Science Technology program at the Rochester Institute of Technology/National Technical Institute for the Deaf will be shared, as it produces a number of the modern-day successful deaf and hard-of-hearing scientists.

 
 
 
Greg Williams, Bridging the gap between books and bench for students with disabilities
Closed Captioned, Transcript

The Institute for Accessible Science (IAS) was established at Purdue University in 2010 through funding by the NIH Director's Pathfinder Award to broaden the participation of persons with disabilities (PWDs) in STEM careers. The mission of the IAS is to target and break down attitudinal and physical barriers that PWDs face in biomedical science. The IAS has a three pronged approach to achieving this mission. 1) develop accessible laboratory equipment to enable PWDs to perform common lab procedures as independently as possible. 2) provide opportunities for PWDs to gain practical experience in a research laboratory utilizing IAS' expertise in STEM accessibility. 3) create an on-line environment (iashub.org) to provide education and support for PWDs regarding STEM accessibility along with a forum where they can receive guidance from peers and mentors. We will describe some of these efforts, discuss their success, and look toward the future as IAS forges ahead.

 

 

E. V. Murphree Award in Industrial and Engineering Chemistry: Symposium in Honor of Esther S. Takeuchi

Division of Energy and Fuels

Elsa Reichmanis, Approaches to achieving more efficient photovoltaic devices

Solution-processed π–conjugated semiconductors exhibit potential in the development of low-cost, light-weight and large-area flexible plastic optoelectronics, particularly photovoltaics (OPVs). However, one drawback to current OPVs is their limited efficiency. We have explored the use of donor-acceptor (D-A) hybridization to tailor HOMO/LUMO energy levels and thus the band gap. Materials exhibiting high charge carrier mobility and strong low-energy absorption profiles have been synthesized and characterized. Further, to provide for a still higher level of photon absorption, we have explored the applicability of photon upconversion (UC). Specifically, a core-shell structure that provides for low-threshold TTA-based UC within a structure that could be readily incorporated into a photonic device was developed. The fabrication of core-shell UC microcapsules was demonstrated using microfluidic fabrication process. Self-assembled capsule arrays offer outstanding optical emission under ultralow power excitation and may be effective in OPV efficiency enhancement.
