Energy dissipation mechanisms in an acoustically driven slit

We quantify the conversion of incident acoustic energy into vortical motion and viscous dissipation for a plane wave passing through large-aspect-ratio slit geometries. We perform direct numerical simulations over a broad imposed parameter space in incident sound pressure level (...

Trions as Fundamental Species in Chemically Doped Polymer Semiconductors

Doping is a cornerstone strategy for enhancing charge transport in semiconducting polymers, important for their application in, for example, semi-transparent electrode materials, thermoelectric devices, and antistatic coatings. Both chemical and electrochemical doping have, for t...

MitigatingSO2 Poisoning Effect in ElectrochemicalCO2 Reduction with Transition-Metal Single-Atom MolecularCatalysts

Abstract The electrochemical CO2 reduction reaction (CO2RR) offers a promising approach for converting captured CO2 into valuable chemicals and fuels. However, CO2 streams from industrial sources often contain SO2 impurities, which compromise the performance and stability of many...

AI Designed Conformation Locking Peptides Target STING to Restore Diabetic Wound Healing

ABSTRACT Diabetic foot ulcers are a major complication of diabetes characterized by persistent inflammation and impaired tissue repair, in part driven by aberrant activation of the cGAS‐STING innate immune pathway. Precision immunomodulation in the protease‐rich wound microenviro...

Navigating the Battlefield: How Social Media Platforms Respond to Governance Demands From Legitimacy Communities in Geopolitical Conflicts

ABSTRACT Social media platforms have become central actors in governing online speech during geopolitical conflicts, navigating complex governance demands from diverse stake‐holding communities including states, civil society, and users. This paper explores these dynamics through...

The Uniqueness of the Ground State and the Dynamics of Nonlinear Schrödinger Equation with Inverse Square Potential

Abstract. In this paper, we first provide an alternative proof of the uniqueness of the ground state solution for nonlinear Schrödinger equation (NLS) with inverse square potential and power nonlinearity [Formula: see text] for all [Formula: see text] in dimensions [Formula: see...

Flux-Driven Order–Disorder Polymorphs of KagomeSmFe6Ge6

Abstract While polymorphism in kagome-derived intermetallics offers a powerful route to controlling structure–property relationships, it still remains poorly explored for many rare-earth members due to synthetic constraints. Here, we report the discovery and controlled growth of...

Considerations for Ammonia-fuelled Aircraft and Propulsion Systems: A Component-level and System Analysis

Abstract Alternative fuels for aviation as substitutes for Jet-A are currently being investigated globally. Ammonia has emerged as a potential candidate given its robust supply chain, technological maturity, and global infrastructure. Ammonia combustion at scale has been successf...

What is happening at the atomic level during the seed-mediated growth of copper on gold?

Bimetallic nanocrystals obtained via seed-mediated growth are typically analyzed using conventional electron microscopy and many interesting features at the atomic level are often missed. Here we report the seed-mediated growth of copper (Cu) on gold (Au) nanospheres for the synt...

Multimodal radiopathological integration for prognosis of limited and extensive stage small cell lung cancer

Small-cell lung cancer (SCLC) is an aggressive malignancy with poor survival and no validated prognostic biomarkers. We developed and validated a multimodal artificial intelligence–based radiopathomic framework to predict progression-free survival (PFS) by integrating radiologic...

Highly Repeatable Fibrous Crack‐Based Strain Sensor for Multichannel Continuous Tremor Monitoring in Parkinson's Disease and Essential Tremor

ABSTRACT Objective measurement of tremors is important for assessing the severity and preventing misdiagnosis of Parkinson's disease (PD). To address this demand, this study presents a multichannel, wireless, patch‐type tremor monitoring system that integrates a high‐repeatable f...

Acoustic iso-propagation vortices for robust underwater communications

Underwater acoustic communications are limited by low information capacity and data rate. While orbital-angular-momentum (OAM) multiplexing can address these issues, conventional OAM beams scale poorly in realistic ocean environments over long distances because their beam diamete...
