The continuing struggle to clean London’s air《論文》

open access: yesThe continuing struggle to clean London’s air《論文》
Pollution from smoke has been a problem ever since people first started to make fires in order to cook food, to keep warm, and to work metals. The problem became far worse in London with its rapid growth and industrialisation during the nineteenth century, but little effective action was taken until the London fog of 5 to 8 December 1952 that resulted ...

Scalable Thermal Engineering via Femtosecond Laser‐Direct‐Written Phononic Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates that femtosecond laser‐induced periodic surface structures (fs‐LIPSS) can function as phononic metasurfaces, reducing thermal conductivity below the plain thin‐film limit. Phonon Monte Carlo analysis reveals that the periodic structures restrict phonon mean free paths.

Interior Hulls of Clean Lattice Parallelograms and Continued Fractions

open access: yes
The interior hull of a lattice polygon is the convex closure of the lattice points in the interior of the polygon. In this paper we give a concrete description of the interior hull of a clean lattice parallelogram. A clean parallelogram in $\mathbb{R}^2$ is a lattice parallelogram whose boundary contains no lattice points other than its vertices. Using

Universal Electronic‐Structure Relationship Governing Intrinsic Magnetic Properties in Permanent Magnets

open access: yesAdvanced Functional Materials, EarlyView.
Permanent magnets derive their extraordinary strength from deep, universal electronic‐structure principles that control magnetization, anisotropy, and intrinsic performance. This work uncovers those governing rules, examines modern modeling and AI‐driven discovery methods, identifies critical bottlenecks, and reveals electronic fingerprints shared ...
