Approaches to Evaluating and Improving Lithium-Ion Battery Safety

submitted by: RASEIBoulder
As lithium-ion battery technologies mature, the size and energy of these systems continues to increase for emerging applications in transportation, grid storage, military use and aerospace. In fact, broadening the application space for lithium-ion batteries from the consumer electronics industries to these emerging markets increases their size from 1-50 Wh batteries for smart phones and laptops to >50 kWh for electric vehicles (EVs) and MWh scale for utility storage systems. As these...

The Promise of Lean in Healthcare

submitted by: WentzMR

Dr. John Toussaint, Internist and CEO emeritus of the ThedaCare Center for Healthcare Value in Appleton, WI, discusses his article co-authored with Leonard Berry and appearing in the January 2013 issue of Mayo Clinic Proceedings, where he introduces the “lean” methodology in healthcare and explains how to implement it.

Making Most of the Absorbed Photon: New Insights into Carrier Multiplication in Semiconductor Nanostructures

submitted by: RASEIBoulder
Carrier multiplication (CM) or multiexciton generation (MEG) is a process whereby absorption of a single photon produces multiple electron-hole pairs (excitons). CM could benefit a number of solar-energy conversion technologies, most notably photocatalysis and photovoltaics. This presentation overviews recent progress in understanding of the CM process in semiconductor nanocrystals, motivated by an outstanding challenge in this field - the lack of capability to quickly discern between...

Systems as the Driver for Synthetic Biology

submitted by: RASEIBoulder
We now possess the ability to read and write DNA. These tools are not only revolutionizing biotechnology but also the basic life sciences as well. The challenge is that we are still learning the grammar. In other words, we often do not know which genetic perturbations to make in order to alter the behavior of an organism. As a result, synthetic biology still involves much trial and error. Moreover, we are still far from the point where we can engineer new organisms from scratch – rather,...

School Lunch Waste Among Middle School Students: Nutrients Consumed and Costs

submitted by: Jfwcohen
Background: The National School Lunch Program has been guided by modest nutrient standards, and the palatability of meals, which drives consumption, receives inadequate attention. School food waste can have important nutritional and cost implications for policymakers, students, and their families. Purpose: Nutrient losses and economic costs associated with school meal waste were examined. The study also assessed if school foods served were valid proxies for foods consumed by students....
