Hierarchical Strain‐Modified Medium‐Entropy Carbide Ceramics Exhibit Exceptional Ablation Resistance up to 2400°C

open access: yesAdvanced Science, EarlyView.
A novel strategy is developed by doping reduced graphene oxide (rGO) into a (HfZrTi)C medium‐entropy ceramic. This induces a hierarchical strain modification mechanism, synergistically inhibiting crack propagation at the microscale and dissipating stress at the mesoscale.

Improved Air Stability of Li Argyrodites Through PS43− Rotation Suppression by Al and Se Co‐Substitution for All‐Solid‐State Batteries

open access: yesAdvanced Science, EarlyView.
Al/Se co‐substitution in Li6PS5Cl achieves enhanced dry‐air stability and improves Li+ conductivity, retaining 85% of its high Li+ conductivity (4.91 mS cm−1 at 30 °C) after dry‐air exposure (dew point −40 °C for 5 h). The stability enhancement is experimentally validated and underpinned by theoretical analyses indicating suppressed rotation of P[S2SeO]

Advertising as governance: The digital commodity audience and platform advertising dependency

open access: yesMedia, Culture & Society
This article draws from an ethnographic investigation of YouTube to argue the significant and specific role of advertising in the governance of platformised cultural production. We pursue this investigation in a critical dialog with theoretical approaches drawn from platform governance, platformisation and political economy communications ...

Scrambling‐Enhanced Quantum Battery Charging in Black Hole Analogues

open access: yesAdvanced Science, EarlyView.
By employing a black‐hole‐analog quantum battery constructed from a position‐dependent XY model, its dynamical behavior is investigated through a quench of the scrambling parameter. It is systematically quantified that how the simulated scrambling improves key performance metrics‐namely, stored energy, peak power, and charging time‐thereby offering a ...

Cyber-Democracy or Cyber-Hegemony? Exploring the Political and Economic Structures of the Internet as an Alternative Source of Information [PDF]

open access: yes, 2005
Although government regulation of the Internet has been decried as undercutting free speech, the control of Internet content through capitalist gateways???namely, profit-driven software companies???has gone largely uncriticized. The author argues that

Private Provision of a Complementary Public Good [PDF]

open access: yes, 2006
For several years, an increasing number of firms are investing in Open Source Software (OSS). While improvements in such a non-excludable public good cannot be appropriated, companies can benefit indirectly in a complementary proprietary segment.

Decoding Proton‐Coupled Electron Transfer Mechanism of Nicotine for Multi‐Scenario Portable Electrochemical Sensing

open access: yesAdvanced Science, EarlyView.
A key challenge in nicotine electroanalysis is the unresolved complexity of its interface process, which directly determines sensor metrics. Herein, the proton‐coupled electron transfer mechanism of nicotine is decoded for multi‐scenario portable electrochemical sensing.

It Depends on What the Meaning of False is: Falsity and Misleadingness in Commercial Speech Doctrine [PDF]

open access: yes, 2007
While scholarship regarding the Supreme Court\u27s noncommercial speech doctrine has often focused on the level of protection for truthful, non-misleading commercial speech, scholars have paid little attention to the exclusion of false or misleading ...

Unsupervised Hierarchical Symbolic Regression for Interpretable Property Modeling in Complex Multi‐Variable Systems

open access: yesAdvanced Science, EarlyView.
UHSR translates complex chemical behavior into clear and explainable equations. Applied to thin‐layer chromatography, it automatically uncovers the mathematical rules linking a molecule's structure to its polarity. This approach matches the accuracy of advanced AI while providing interpretable results, earning greater trust from chemists. The method is
