Small-area Population Forecast in a Segregated City using Density-Functional Fluctuation Theory

Posted by klaurent Cornell

Kavli Affiliate: Itai Cohen | First 5 Authors: Yuchao Chen, Yunus A. Kinkhabwala, Boris Barron, Matthew Hall, Tomas A. Arias | Summary: Decisions regarding housing, transportation, and resource allocation would all benefit from accurate small-area population forecasts. While various tried-and-tested forecast methods exist at regional scales, developing an accurate neighborhood-scale forecast remains a challenge partly […]

Charging-driven coarsening and melting of a colloidal nanoparticle monolayer at an ionic liquid-vacuum interface

Posted by klaurent Berkeley

Kavli Affiliate: Naomi S. Ginsberg | First 5 Authors: Connor G. Bischak, Jonathan G. Raybin, Jonathon W. Kruppe, Naomi S. Ginsberg, | Summary: We induce and investigate the coarsening and melting dynamics of an initially static nanoparticle colloidal monolayer at an ionic liquid-vacuum interface, driven by a focused, scanning electron beam. Coarsening occurs through grain […]

Designing angle-independent structural colors using Monte Carlo simulations of multiple scattering

Posted by klaurent Harvard

Kavli Affiliate: Vinothan N. Manoharan | First 5 Authors: Victoria Hwang, Anna B. Stephenson, Solomon Barkley, Soeren Brandt, Ming Xiao | Summary: Disordered nanostructures with correlations on the scale of visible wavelengths can show angle-independent structural colors. These materials could replace dyes in some applications because the color is tunable and resists photobleaching. However, designing […]
