The Sonora Substellar Atmosphere Models. VI. Red Diamondback: Extending Diamondback with SPHINX for Brown Dwarf Early Evolution

The Astrophysical Journal
We extend the Sonora Diamondback brown dwarf evolution models to higher effective temperatures to treat the evolution of younger, higher-mass objects. Due to an upper temperature limit of T _eff  =  2400 K in the original Sonora Diamondback model grid ...

Accelerated Discovery of Topological Conductors for Nanoscale Interconnects

Advanced Science, EarlyView.
Copper interconnects exhibit a sharp increase in resistivity at ultra‐scaled dimensions, threatening continued miniaturization of integrated circuits. The gapless surface states of topological semimetals provide conduction channels resistant to localization.

A Survey of Model Fits to Brown Dwarf Spectra Through the L–T Sequence

The Astronomical Journal
We fit archival near-IR spectra of ∼300 brown dwarfs with atmosphere models from the Sonora and Phoenix groups. Using the parameters of the best-fit models as estimates for the physical properties of the brown dwarfs in our sample, we have performed a ...

Reversible and Controllable Transition Between Filamentary and Interfacial Resistive Switching in HfO2‐Based Memristors

Advanced Electronic Materials, EarlyView.
5 nm HfO2 memristors exhibit a fully reversible, voltage‐controlled transition between filamentary and interfacial switching within the same device. At high voltages, a filament forms and dominates the conduction, whereas at lower voltages the device reversibly returns to interfacial mode without defect accumulation, implying a new reversible ...

Radical Electroprecipitation from a Water|Oil|Electrode Interface Prolongs “Electro”Chemiluminescence of the Tris(2,2′‐bipyridyl)Ruthenium(II) and Benzoyl Peroxide System by 103

Angewandte Chemie, EarlyView.
Multiphase systems, including ones with liquid‐liquid phase boundaries, are the home to many curious chemistries including reaction acceleration and spontaneous formation of reactive species. Here we show the liquid‐liquid interface causes electrochemiluminescence and afterglow chemiluminescence lifetime to be enhanced by 220,000% in‐time, far beyond ...

Climate Change Agricultural Comparative Advantage and the US Trade Balance

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Current science indicates that warming and elevated atmospheric CO2 will have ambiguous results for crop productivity depending on crop type and geographic location, whereas increased heat stress makes livestock and human labor less productive.
