Time-resolved imaging of antiferromagnetic skyrmion interactions

Abstract Quantifying particle interactions is central to understanding and controlling collective dynamics in particle-based devices such as those comprising skyrmion ensembles. Here we directly visualize, in real time, the nanosecond current-driven dynamics of an antiferromagnet...

Electrostatically Limited PFSA Ionomer Adsorption to Catalyst Particles in Catalyst Inks

Abstract Understanding and controlling ionomer adsorption in catalyst inks is critical to optimizing catalyst-layer structure and performance in membrane-electrode assemblies. Here, we systematically quantify perfluorosulfonic-acid (PFSA) ionomer adsorption across a diverse set o...

Identification of a key water molecule involved in the macrophage migration inhibitory factor‐catalyzed tautomerization of para ‐hydroxyphenylpyruvate using neutron crystallography

Neutron crystallography was used to determine a 2.5-Å resolution all-atom structure of macrophage migration inhibitory factor (MIF) interacting with 3-(4-hydroxyphenyl)-pyruvate (HPP). MIF is a pro-inflammatory, pro-tumorigenic protein that may be an attractive therapeutic target...

Evaluating technology upgrades as a complement to traditional bill assistance programs

State programs to improve energy affordability and reduce energy burden (the share of income spent on energy) could mitigate concerns about rising electricity prices. Many states offer bill assistance and rebates for weatherization and rooftop solar to income-qualifying household...

Bridging Nanoscopic Surface Heterogeneity and MacroscopicNucleation Rates: A Perspective on Probabilistic Approaches

Abstract Predicting the number of newly formed crystals and their spatial distribution on surfaces or within pore spaces matters across many fields, from structural biology to coupled fluid flow and reactive transport in porous media to atmospheric physics. Nucleation occurs at m...

Review of Particle Physics *

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,200 new measurements from 903 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and b...

Hydration-dependent exciton-phonon coupling in a metal-organic framework photocatalyst

Abstract Metal-organic frameworks (MOFs) have potential for light-harvesting applications owing to their tunable optoelectronic properties via building block selection. The presence of bound solvent in MOFs is known to impact gas adsorption properties, but little is known about t...
