Publikováno v: Nano Research, vol 14, iss 10

The biggest challenge of exploring the catalytic properties of under-coordinated nanoclusters is the issue of stability. We demonstrate herein that chemical dopants on sulfur-doped graphene (S-G) can be utilized to stabilize ultrafine (sub-2 nm) Au25

Approaching 100% Selectivity at Low Potential on Ag for Electrochemical CO2 Reduction to CO Using a Surface Additive

Autor: Buckley, AK, Cheng, T, Oh, MH, Su, GM, Garrison, J, Utan, SW, Zhu, C, Toste, FD, Goddard, WA, Toma, FM

Publikováno v: ACS Catalysis, vol 11, iss 15

We report the discovery of a quaternary ammonium surface additive for CO2 reduction on Ag surfaces that changes the Faradaic efficiency for CO from 25% on Ag foil to 97%, while increasing the current density for CO production by a factor of 9 from 0.

Permeation of CO2 and N2 through glassy poly(dimethyl phenylene) oxide under steady‐ and presteady‐state conditions

Autor: Soniat, M, Tesfaye, M, Mafi, A, Brooks, DJ, Humphrey, ND, Weng, LC, Merinov, B, Goddard, WA, Weber, AZ, Houle, FA

Publikováno v: Journal of Polymer Science, vol 58, iss 9

Glassy polymers are often used for gas separations because of their high selectivity. Although the dual-mode permeation model correctly fits their sorption and permeation isotherms, its physical interpretation is disputed, and it does not describe pe

Identification of the Selective Sites for Electrochemical Reduction of CO to C 2+ Products on Copper Nanoparticles by Combining Reactive Force Fields, Density Functional Theory, and Machine Learning

Autor: Huang, Y, Chen, Y, Cheng, T, Wang, LW, Goddard, WA

Publikováno v: ACS Energy Letters, vol 3, iss 12

Recent experiments have shown that CO reduction on oxide derived Cu nanoparticles (NP) are highly selective toward C 2+ products. However, understanding of the active sites on such NPs is limited, because the NPs have 200 000 atoms with more than 10

Publikováno v: Favaro, M; Xiao, H; Cheng, T; Goddard, WA; & Crumlin, EJ. (2017). Subsurface oxide plays a critical role in CO2 activation by Cu(111) surfaces to form chemisorbed CO2, the first step in reduction of CO2.

A national priority is to convert CO2 into high-value chemical products such as liquid fuels. Because current electrocatalysts are not adequate, we aim to discover new catalysts by obtaining a detailed understanding of the initial steps of CO2 electr

Almost Injective Colorings

Autor: Goddard Wayne, Melville Robert, Xu Honghai

Publikováno v: Discussiones Mathematicae Graph Theory, Vol 39, Iss 1, Pp 225-239 (2019)

We define an almost-injective coloring as a coloring of the vertices of a graph such that every closed neighborhood has exactly one duplicate. That is, every vertex has either exactly one neighbor with the same color as it, or exactly two neighbors o
