Burdyny, T.E. (author), Sassenburg, M. (author), de Rooij, R. (author), Nessbit, Nathan (author), Kas, R. (author), Chandrashekar, S. (author), Firet, N.J. (author), Yang, K. (author), Liu, K. (author), Blommaert, M.A. (author), Kolen, M. (author), Ripepi, D. (author), Smith, W.A. (author)Continued advancements in the electrochemical reduction of CO 2 (CO 2RR) have emphasized that reactivity,selectivity, and stability are not explicit material properties butcombined effects of the catalyst, double-layer, reaction environ-<br/>ment, and system configuration. These realizations have steadily built upon the foundational work...journal article 2022

(author), Bisquert, Juan (author), Gimenez, Sixto (author), Smith, W.A. (author)Au-Cu bimetallic thin films with controlled composition were fabricated by magnetron sputtering co-deposition, and their performance for the electrocatalytic reduction of CO <sub>2</sub> was investigated. The uniform planar morphology served as a platform to evaluate the electronic effect isolated from morphological effects while minimizing...journal article 2019

Ma, M. (author), Liu, K. (author), Shen, J. (author), Kas, R. (author), Smith, W.A. (author)In this work, the highly selective and stable electrocatalytic reduction of CO<sub>2</sub> to CO on nanostructured Ag electrocatalysts is presented. The Ag electrocatalysts are synthesized by the electroreduction of Ag<sub>2</sub>CO<sub>3</sub> formed by in situ anodic-etching of Ag foil in a KHCO<sub>3</sub> electrolyte. After 3 min of this...journal article 2018

Šavija, B. (author), Smith, G.E. (author), Liu, D (author), Schlangen, E. (author), Flewitt, P.E.J. (author)Deformation and fracture of materials are usually considered in terms of brittle and ductile modes. However, there is an intermediate class between these limits that is termed quasi-brittle where there is measurable inelastic deformation prior to final graceful ‘brittle’ failure. In previous work, we presented deformation and fracture data...journal article 2018

ten Veldhuis, Marie-claire (author), Zhou, Zhengzheng (author), Yang, Long (author), Liu, Shuguang (author), Smith, James (author)The impact of spatial and temporal variability of rainfall on hydrological response remains poorly understood, in particular in urban catchments due to their strong variability in land use, a high degree of imperviousness and the presence of stormwater infrastructure. In this study, we analyze the effect of storm scale, position and movement...journal article 2018

Zhou, Zhengzheng (author), Smith, James A. (author), Yang, Long (author), Baeck, Mary Lynn (author), Chaney, Molly (author), ten Veldhuis, Marie-claire (author), Deng, Huiping (author), Liu, Shuguang (author)We examine urban flood response through data-driven analyses for a diverse sample of “small” watersheds (basin scale ranging from 7.0 to 111.1 km<sup>2</sup>) in the Charlotte Metropolitan region. These watersheds have experienced extensive urbanization and suburban development since the 1960s. The objective of this study is to develop a...journal article 2017

(author)In this work, porosity-property relationships of quasi-brittle materials are explored through a combined experimental and numerical approach. In the experimental part, hemihyrate gypsum plaster powder (CaSO 4 ⋅1/2H 2 O CaSO4⋅1/2H2O) and expanded spherical polystyrene beads (1.5–2.0 mm dia.) have been mixed to form a model material with...journal article 2017

Heard, P (author), Šavija, B. (author), Liu, D (author), Smith, GE (author), Hallam, KR (author), Schlangen, E. (author), Flewitt, P.E.J. (author)In quasibrittle materials the addition of specific microstructural features such as porosity can lead to departure from linear elastic behaviour prior to maximum force, followed by graceful failure. A simple but extreme example is reticulated vitreous carbon foam, with its opencell structure of brittle ligaments connected in a threedimensional...conference paper 2016

Liu, D. (author), Heard, P. (author), Savija, B. (author), Smith, G. (author), Schlangen, E. (author), Flewitt, P. (author)In the present work, the microstructure and mechanical properties of Gilsocarbon graphite have been characterized over a range of length-scales. Optical imaging, combined with 3D X-ray computed tomography and 3D high-resolution tomography based on focus ion beam milling has been adopted for microstructural characterization. A range of small...conference paper 2015

(author)Data assimilation (DA) holds considerable potential for improving hydrologic predictions as demonstrated in numerous research studies. However, advances in hydrologic DA research have not been adequately or timely implemented in operational forecast systems to improve the skill of forecasts for better informed real-world decision making. This is...journal article 2012

(author)In this paper we present a solution for efficient porting of sequential C++ applications on the Cell B.E. processor. We present our step-by-step approach, focusing on its generality, we provide a set of code templates and optimization guidelines to support the porting, and we include a set of equations to estimate the performance gain of the new...conference paper 2007
