Epsilon‐Negative Derived Electromagnetic Wave Absorption of Magnetic Metacomposites by Bifunctional Phase Paradigm

open access: yesAdvanced Science, EarlyView.
An epsilon‐negative response of up to 100000 in the radio frequency band is achieved by creating a metacomposite system with graphene/iron (III) oxide as the main body. The magnetic metacomposites are just like the mythical creature Qiongqi in Chinese mythology, capable of swallowing electromagnetic wave pollution that falls from the sky.

Multi‐Soliton Microcombs Enable Ultrafast Nanometric‐Precision Ranging and Photon‐Level Detection

open access: yesAdvanced Science, EarlyView.
Our work first demonstrates dual‐multi‐soliton ranging and confirms its multifunctional capability. The method achieves ultrafast and nanometric‐precision measurement. For practical applications, we further extend the multi‐soliton states to photon‐level ranging.

Machine Learning for Green Solvents: Assessment, Selection and Substitution

open access: yesAdvanced Science, EarlyView.
Environmental regulations have intensified demand for green solvents, but discovery is limited by Solvent Selection Guides (SSGs) that quantify solvent sustainability. Training a machine learning model on GlaxoSmithKline SSG, a database of sustainability metrics for 10,189 solvents, GreenSolventDB is developed. Integrated with Hansen solubility metrics,
