Redox Buffering and Corrosion in Molten Chloride Salts Dictated by Chlorobasicity

Abstract This study establishes an in situ synchrotron approach to directly link molten-salt chemistry, redox-buffer speciation, and alloy corrosion in chloride melts. Using a first-of-its-kind corrosion cell coupled to simultaneous X-ray absorption spectroscopy (XAS) and X-ray f...

Direct Measurements and Analysis of Catalyst Diffusion and Reaction Fronts in Chemically Amplified Resists

Abstract The propagation of both catalyst diffusion and reaction fronts in a polymeric chemically amplified resist (CAR) is evaluated by time-of-flight secondary ion mass spectrometry (TOF-SIMS) depth profiling, and is compared with the propagation of catalyst diffusion fronts in...

Offshore Freshened Groundwater Distribution Is Controlled by Along‐ and Cross‐Shore Topographic Variability

Abstract Offshore Freshened Groundwater (OFG) reservoirs are regarded as a potentially significant resource stored in continental shelves. While the role of subsurface geological conditions in controlling OFG has been widely recognized, the influence of the topography of the host...

Probing Executive Function in the Toddler Data Desert: A Touchscreen fNIRS Study of Working Memory and ADHD-Related Symptoms

Attention-deficit/hyperactivity disorder (ADHD) is associated with early differences in attentional control and working memory (WM), yet relatively few paradigms are developmentally feasible across the toddler-to-preschool period while also distinguishing spatial from featural in...

The Emergence of the Service Techonomy: POPP at the Frontlines and the Rise of AI-Mediated Service Influence

Advances in artificial intelligence (AI), data infrastructures, and platform technologies are reshaping services and organizational frontlines. We conceptualize this shift as the emergence of the “service techonomy,” in which omni-personalization manifests via Prescribed, Omnipre...

Morphology and Ion Transport in Zwitterionic Polysiloxanes

Abstract The recent discovery of superionic conductivity in doped polyzwitterions (PZIs) has opened a new direction for polymer electrolytes (PEs). Solid-state battery research is currently dominated by inorganic electrolytes due to their rigidity and high conductivity, but they...

Antiferromagnetism and tightly bound Cooper pairs induced by kinetic frustration

Antiferromagnetism and superconductivity are often viewed as competing orders in correlated electron systems. Here, we demonstrate that kinetic frustration in hole motion facilitates their coexistence within the square-lattice repulsive Hubbard model. Combining exact analytical s...

Project: Privacy-Preserving Federated Learning for Science

This repository is part of a U.S. Department of Energy (DOE) Advanced Scientific Computing Research (ASCR) project focused on developing privacy-preserving federated learning approaches for scientific foundation models. The project aims to advance secure, trustworthy, and sustain...

Structural Evolution and Chemical Incorporation Pathways in Wadsley-Roth Oxides

Abstract We investigate solid-state reaction pathways to high-temperature phase formation in the entropy-stabilized Wadsley-Roth Ti(NbxTa1–x)2O7 phases. We analyze and discuss thermodynamic and kinetic factors governing these processes in TiNb2O7, TiTa2O7, and Ti(NbTa)2O7. Diffra...

Discovery and Optimization of a Novel Brain-Penetrant Colchicine-Binding Site Ligand for Treatment of Glioma

Abstract The limited number of approved drugs for treatment of brain cancers is very apparent. Temozolomide and Vorasidenib continue to be the only approved brain-permeable, orally available drugs. A novel class of highly brain-penetrant tubulin-binding ligands was discovered thr...

Reaffirming the validity of unobtrusive personality measures: A comment on Harms et al. (2025) and guidance for the field

Abstract As unobtrusive measures of CEO personality have become more common in organizational research, questions about their validity have grown. Harms et al., Journal of Occupational and Organizational Psychology, (2025) 98, e70052 recently formalized some of these concerns in...

Nonlinear Quantum Effects Drive Grotthuss Proton Conduction in Structured Electrolytes Based on Deep Eutectic Solvents

ABSTRACT Structured electrolytes based on deep eutectic solvents (DESs) face electrochemical limitations of vehicular diffusion due to high viscosities often leading to low conductivities. Here, we demonstrate that the inverse relationship between viscosity and conductivity in DE...

A longitudinal comparison of shared and private e-scooter crashes, near-miss rates, attributions and characteristics

As e-scooters have become increasingly common in urban areas, safety concerns have grown. However, most safety research does not distinguish between shared and private e-scooter use. Moreover, no studies have examined within-person changes in safety outcomes over time. This study...

Beyond Scalar Objectives: Expert-Feedback-Driven Autonomous Experimentation for Scientific Discovery at the Nanoscale

Abstract Self-driving laboratories or autonomous experimentation are emerging as transformative platforms for accelerating scientific discovery. Bayesian optimization (BO) is among the most widely used machine learning frameworks in self-driving laboratories, but these BO-based f...

The measurement of Christian nationalism in broader perspective: a systematic reevaluation

Abstract The literature on Christian nationalism has expanded and matured quickly. Nonetheless, few pieces have documented the measurement properties of its namesake concept, and those that have trumpet conclusions that vary from “the most common measure is flawed” to “Christian...

Directing the Labor Market: Shared Directors and Employee Flows

Abstract Using résumé data on over 20 million U.S. workers, we find that the flow of employees between a pair of firms sharply drops by about 20% during periods in which the firms share a board director. This relationship is stronger in settings where firms have greater potential...

Environmental, developmental, and genetic factors differentially affect rapid ethylene growth response kinetics in dark-grown Arabidopsis thaliana hypocotyls

Studies on dark-grown wild-type Arabidopsis thaliana seedlings have demonstrated that the hypocotyls respond to the application and removal of the hormone ethylene with stereotypical growth kinetics. This includes a rapid decrease in growth rate when ethylene is applied that stab...

Closing Data Gaps in Regional Glacier Trends of the Wind River Range, Wyoming, USA

Glaciers in Wind River Range, Wyoming, have experienced substantial reductions in surface area and volume in recent decades, yet existing inventories contain temporal gaps and often mix glaciers with seasonal snowpack. We mapped and classified glacier outlines using high-resoluti...

The longitudinal co-development of adverse childhood experiences and child internalizing problems: Examining sociodemographic disparities

Abstract Internalizing problems are prevalent in childhood and are associated with exposure to adverse childhood experiences (ACEs); however, their co-development across childhood remains understudied. Prior research documents sociodemographic disparities (i.e., race/ethnicity, s...

Adsorption of Polyolefins from Alkanes on Alumina and Silica

Abstract Heterogeneous catalytic deconstruction of polyolefins offers a promising route to upcycle plastic waste into higher-value products, yet the fundamental insights needed to control product distributions remain limited. As the reactions proceed, deconstruction generates a d...
