Ethical Precision in Nanoscale Brain Interfacing
Advanced Science, EarlyView.As brain interfaces approach the nanoscale, precision no longer only measures—it knows, predicts, and potentially reshapes the mind. This work argues that traditional ethics fails under such conditions and proposes a shift toward continuous, operation‐based governance using the recovery–discovery framework to track, constrain, and responsibly steer ...

Advanced Science, EarlyView.A mechanically adaptive polyimide interface dynamically stabilizes single‐crystal cathodes in sulfide all‐solid‐state batteries. By integrating robust chemical coordination with viscoelastic compliance, this smart coating suppresses parasitic reactions and accommodates cyclic volume expansion.

Angewandte Chemie, EarlyView.A photocatalytic approach for efficient one‐pot direct lignin depolymerization and subsequent cross‐coupling with alcohols for the production of unsymmetrical aromatic diols has been demonstrated. ABSTRACT Conversion of lignin into chemical products typically involves two separate steps, such as depolymerization and subsequent upgrading of monomers ...

Advanced Science, EarlyView.An interpretable machine learning framework integrating SHAP and PDP analysis identifies critical design descriptors from 139 physicochemical features for Nb─Si alloys. The framework achieves <7% prediction error and guides the discovery of Nb38.5Ti38.5Si3Zr18V2 alloy with 22.791 MPa·m1/2 fracture toughness, breaking the 20 MPa·m1/2 barrier.

Collective Knowledge on Aviation Gasolines [PDF]
, 2011 The problem being faced is that there exists little data in a collective location surrounding aviation gasolines. In recent years it has been observed that most involved in the general aviation community are unaware of efforts and solutions underway to ...

Advanced Science, EarlyView.An extreme non‐equilibrium process combining heavy direct current sintering and TiSi2 addition is used to construct intragranular energy dissipation units within high‐entropy boride ceramics to overcome the strength‐toughness trade‐off. The resulting ceramic demonstrates attractive mechanical properties with a flexural strength of 887 MPa and a ...
