Symmetry Breaking in Chemical Systems: Engineering Complexity Through Self‐Organization and Marangoni Flows

open access: yesAdvanced Science, EarlyView.
We show that solutal Marangoni flows in thin films climbing the outer surfaces of hydrophilic obstacles break circular Belousov‐Zhabotinsky waves into striking flower‐like patterns. Evaporation‐driven surface‐tension gradients, coupled with gravity, trigger the instability; above a threshold, petal number scales linearly with obstacle diameter ...

Complex epithelial remodeling underlie the fusion event in early fetal development of the human penile urethra. [PDF]

open access: yes, 2016
We recently described a two-step process of urethral plate canalization and urethral fold fusion to form the human penile urethra. Canalization ("opening zipper") opens the solid urethral plate into a groove, and fusion ("closing zipper") closes the ...

Small and Simple Molecular Structure Based Thermally Stable Ruthenium Precursor in Advancing Ruthenium ALD Process for Scaled Interconnect Metallization

open access: yesAdvanced Science, EarlyView.
A thermally robust (≈400 °C), critically small‐size‐simple ligand structure ruthenium (Ru) precursor enables exceptional growth per cycle (≈1.28 Å cycle−1), short incubation (≈8 cycles), ultralow resistivity (8.65 µΩ cm) and outstanding substrate selectivity via atomic layer deposition (ALD) process at high temperatures, overcoming prior Ru‐ALD ...

Quantifying the land‐use change due to soybean‐based biodiesel in the United States

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract We quantify the impact of soybean oil‐based biodiesel production on US cropland, using a method that accounts for the intermediate effect of soybean crushing facilities. Based on U.S. Environmental Protection Agency data for biodiesel production and proprietary data for soybean crushing facilities over 2011–2020, we find that the elasticities ...

Dissecting Extreme Price Fluctuations in Mineral Fertilizers: Regularities and Co‐Movements in Light of Global Food Security

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Extreme swings in food prices can put food security at risk. Fertilizer prices are among the main drivers of food prices. This work explores the recurrent behavior of the extreme global fertilizer price fluctuations underlying food price dynamics.
