Strong Metal–Support Interactions Enhance the Activity and Durability of Platinum Supported on Tantalum-Modified Titanium Dioxide Electrocatalysts

Abstract: Rutile phase tantalum-modified titanium oxide (Ta0.3Ti0.7O2) was synthesized and studied using electrochemical and spectroscopic methods to evaluate its efficacy as a corrosion-resistant electrocatalyst support material. A 20 wt % Pt supported on Ta0.3Ti0.7O2 catalyst was prepared and compared in terms of activity and stability against a 20 wt % Pt supported on Vulcan XC-72R carbon catalyst (20% Pt/C; synthesized in-house) and a 46 wt % Pt/C commercially sourced catalyst (Tanaka KK). Catalysts 20% Pt/Ta0.3Ti0.7O2, 20% Pt/C, and 46% Pt/C possessed electrochemically active surface areas (ECSAs) of 60, 57, and 65 m2 g–1, respectively, and mass activities for the oxygen reduction reaction (at 0.9 V vs RHE) of 185, 148, and 224 mA mg–1Pt, respectively, as evaluated in an operating polymer electrolyte fuel cell. Accelerated stability tests (ASTs) were performed on membrane electrode assemblies (MEAs) in an operating fuel cell to investigate both support and platinum catalyst stability. The loss in voltage at a ...

Operationalizing the International Classification of Functioning, Disability and Health in clinical settings

Abstract: Functional status may be a better indicator of health care needs and outcomes than diagnosis. Appropriate use of the International Classification of Functioning, Disability and Health (ICF) in health service settings can provide a standardized way for clinicians to communicate complex clinical assessments to other professionals, administrators, and payers. The American Psychological Association is working with the World Health Organization to develop a Procedural Manual and Guide for a Standardized Application of the ICF for use by multidisciplinary health professionals. The Procedural Manual includes operational definitions of concepts, examples of each code, and assessment information relevant to each qualifier. The purpose of the Procedural Manual is to provide health professionals with the guidance necessary for reliable, valid, and clinically useful classification. This article discusses a range of issues and problems in the application of individual ICF codes in the context of health care and offers some potential solutions.

An Equivalence Between Network Coding and Index Coding

Abstract: We show that the network coding and index coding problems are equivalent. This equivalence holds in the general setting which includes linear and nonlinear codes. Specifically, we present a reduction that maps a network coding instance to an index coding instance while preserving feasibility, i.e., the network coding instance has a feasible solution if and only if the corresponding index coding instance is feasible. In addition, we show that one can determine the capacity region of a given network coding instance with colocated sources by studying the capacity region of a corresponding index coding instance. Previous connections between network and index coding were restricted to the linear case.
