Gravitational Chern-Simons form and Chiral Gravitational Anomaly in Fluid Mechanics [PDF]

arXiv
We show that the hydrodynamic of the perfect fluid admits a deformation that includes a chiral gravitational (or mixed) anomaly alongside the chiral current anomaly. The deformation introduces the gravitational Chern-Simons term and an analog of an axion in fluid mechanics, and features fluid spin-current and anomaly induced spin-orbit interaction.

Decoding Directional Control in Metal‐Assisted Chemical Etching via Catalyst Architecture

Advanced Materials, EarlyView.
Metal‐assisted chemical etching (MaCE) enables silicon nanostructure fabrication but suffers from isotropic undercutting. This study highlights the critical role of catalyst morphology in etching directionality. High‐aspect‐ratio catalysts induce lateral etching, while thermal treatment at 450 °C stabilizes catalyst geometry, promoting vertical etching.

Detecting Cr6+ at ≈100 pM Concentration with Fluorescence Enhancement Signatures in a Novel Eco‐Fluorophore: Matching WHO's 96 pM Recommended Standard for Drinking Water

Advanced Materials, EarlyView.
Through a dual‐functionalization strategy, carbon quantum dots (CQD) with exceptional fluorescence properties are engineered. These CQD are integrated with graphitic carbon nitride to form a 2D/2D heterostructure via both covalent and non‐covalent modification.
