Monodisperse Au nanoparticles for selective electrocatalytic reduction of CO2 to CO.

Abstract: We report selective electrocatalytic reduction of carbon dioxide to carbon monoxide on gold nanoparticles (NPs) in 0.5 M KHCO3 at 25 °C. Among monodisperse 4, 6, 8, and 10 nm NPs tested, the 8 nm Au NPs show the maximum Faradaic efficiency (FE) (up to 90% at −0.67 V vs reversible hydrogen electrode, RHE). Density functional theory calculations suggest that more edge sites (active for CO evolution) than corner sites (active for the competitive H2 evolution reaction) on the Au NP surface facilitates the stabilization of the reduction intermediates, such as COOH*, and the formation of CO. This mechanism is further supported by the fact that Au NPs embedded in a matrix of butyl-3-methylimidazolium hexafluorophosphate for more efficient COOH* stabilization exhibit even higher reaction activity (3 A/g mass activity) and selectivity (97% FE) at −0.52 V (vs RHE). The work demonstrates the great potentials of using monodisperse Au NPs to optimize the available reaction intermediate binding sites for efficient and ...

The home environments of children in the United States part I: variations by age, ethnicity, and poverty status.

Abstract: Although measures of the home environment have gained wide acceptance in the child development literature, what constitutes the “average” or “typical” home environment in the United States, and how this differs across ethnic groups and poverty status is not known. Item-level data from the National Longitudinal Survey of Youth on four age-related versions of the Home Observation for Measurement of the Environment–Short Form (HOME-SF) from five biennial assessments (1986–1994) were analyzed for the total sample and for four major ethnic groups: European Americans, Asian Americans, African Americans, and Hispanic Americans. The percentages of homes receiving credit on each item of all four versions of the HOME-SF are described. For the majority of items at all four age levels differences between poor and nonpoor families were noted. Differences were also obtained among African American, European American, and Hispanic American families, but the magnitude of the effect for poverty status was greater than for ethnicity, and usually absorbed most of the ethnic group effects on HOME-SF items. For every item at every age, the effects of poverty were proportional across European American, African American, and Hispanic American groups.
