DOE/EPRI Electricity Storage Handbook in Collaboration with NRECA.

Abstract: The Electricity Storage Handbook (Handbook) is a how-to guide for utility and rural cooperative engineers, planners, and decision makers to plan and implement energy storage projects. The Handbook also serves as an information resource for investors and venture capitalists, providing the latest developments in technologies and tools to guide their evaluations of energy storage opportunities. It includes a comprehensive database of the cost of current storage systems in a wide variety of electric utility and customer services, along with interconnection schematics. A list of significant past and present energy storage projects is provided for a practical perspective. This Handbook, jointly sponsored by the U.S. Department of Energy and the Electric Power Research Institute in collaboration with the National Rural Electric Cooperative Association, is published in electronic form at www.sandia.gov/ess. This Handbook is best viewed online. iii Rev. 1, February 2015 DOE/EPRI Electricity Storage Handbook in Collaboration with NRECA Revision Log Comments, inquiries, corrections, and suggestions can be submitted via the website www.sandia.gov/ess/, beginning August 1, 2013.

Surface Modification of Poly(methyl methacrylate) Used in the Fabrication of Microanalytical Devices

Abstract: We report here the chemical modification of poly(methyl methacrylate) (PMMA) surfaces by their reaction with the monoanion of α,ω-diaminoalkanes (aminolysis reaction) to yield amine-terminated PMMA surfaces It is found that the amine functionalities are tethered to the PMMA backbone through an alkane bridge to amide bonds formed during the aminolysis of the surface ester functionalities The distribution of the amine termini is quite uniform as judged by fluorescence micrographs It is found that the electroosmotic flow in aminated PMMA microchannels is reversed when compared to that in unmodified channels In addition, it is demonstrated that enzymes can be immobilized onto the amine-terminated PMMA surfaces and are effective in the restriction digestion of dsDNAs Finally, the availability of the surface amine groups is further demonstrated by their reaction with n-octadecane-1-isocyanate to form PMMA surfaces terminated with well-ordered and highly crystalline octadecane chains

The Impact of Stop-Making and Travel Time Reliability on Commute Mode Choice

Abstract: This paper uses revealed preference and stated preference data collected from a web-based commuter survey in Austin, Texas, to estimate a commute mode choice model. This model accommodates weekly and daily commute and midday stop-making behavior, as well as travel time reliability. A mixed logit framework is used in estimation. The results emphasize the effects of commute and midday stop-making on commute mode choice. The results also indicate that travel time reliability is an important variable in commute mode choice decisions. The paper applies the estimated model to predict the potential mode usage of a proposed commuter rail option as well as to examine the impact of highway tolls. More generally, the mode choice model can be used to examine a whole range of travel mode-related policy actions for the Austin metropolitan region.
