Enhanced Ultrasound Transmission Through Aberration Layers Using Space‐Coiling Acoustic Metamaterials

Advanced Engineering Materials, EarlyView.
Enhancing ultrasound transmission through an aberration layer exhibiting mismatched impedance with the surrounding medium possesses great implications in imaging and treatment. In this study, we show that a space‐coiling acoustic metamaterial with judiciously tailored structural profile can help improve impedance matching.

Satellite-Observed Increase in Aboveground Carbon over Southwest China during 2013-2021

Journal of Remote Sensing
Over the past 4 decades, Southwest China has the fast vegetation growth and aboveground biomass carbon (AGC) accumulation, largely attributed to the active implementation of ecological projects.

Climatic Characteristics and Determination Method for Freezing Rain in China

Advances in Meteorology, 2017
The climatic characteristics and temperature profiles of freezing rain in China are analyzed based on the observational data at 650 stations in China from 2000 to 2015. The freezing rain of China is generally in stripe-shape spatial distribution.

HYSPLIT-based demarcation of regions affected by water vapors from the South China Sea and the Bay of Bengal

European Journal of Remote Sensing, 2020
The relationship between atmospheric precipitation and water vapor sources is close, so it is of great significance to carry out the identification of interaction region influenced by different summer monsoons of China.

High‐Performance n‐Type Organic Thermoelectrics Enabled by Control Over Microstructure, Orientation and Contact Plane in Naphthalenediimide‐Bithiazole‐Copolymer Films

Advanced Functional Materials, EarlyView.
Effective control over the crystalline contact plane and microstructure of a naphthalenediimide‐bithiazole copolymer enables high‐performance n‐type thermoelectrics. While rubbing alignment induces a detrimental edge‐on orientation, subsequent solvent vapor‐induced re‐orientation facilitates a favorable mixed face‐on/edge‐on morphology.

Chiral Altermagnetic Magnetoelectrics

Advanced Materials, EarlyView.
In this work, we introduce a previously unexplored class of magnetoelectric materials, which we term chiral altermagnetic magnetoelectrics, in which structural chirality and Néel‐vector‐driven polarization are intrinsically coupled in nonpolar altermagnetic systems.
