Kinetics‐Controlled Architecture of Binder‐Free Organic Electrodes for Enhanced Ion Transport
Advanced Functional Materials, EarlyView.Pulse reverse electrodeposition controls nucleation and growth to create hierarchically porous Py‐derived oligomeric electrodes with enhanced ionic accessibility and reduced transport resistance. The resulting binder‐free architectures translate these transport advantages into practical sodium‐storage functionality.

Advanced Functional Materials, EarlyView.Rapid microwave plasma torch engineering tunes crystal phases, carbon graphitization and oxygen‐vacancy defects in HfO2/C@C core‐shell fibrous membranes. Synergistic multi‐loss effects optimize impedance matching to deliver −65.75 dB reflection loss and a 7.37 GHz effective bandwidth for flexible electromagnetic wave absorption.

Multitask Joint Optimization Based SAR Target Recognition Model From Echo Data
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingTo address the limitations of conventional synthetic aperture radar (SAR) target recognition, particularly the computational redundancy and error accumulation inherent in the imaging-first paradigm, the paper proposes echo-to-class network (E2CNet), an ...

New possibilities and challenges for imaging radar
, 2022 4 S.In 1984, a forward-looking paper by Dale Ausherman was titled: "Devel- opments in Radar Imaging" [1]. Now, 22 years later, we have not reached the end of these developments: new technological possibilities and new insights into the na- ture of radar ...

Advanced Functional Materials, EarlyView.Here, we establish a low‐dose liquid‐phase electron microscopy workflow for real‐time observation of biological processes in hydrated conditions. Beam damage is reduced by imaging only 20% of the pixels and reconstructing the complete image using an inpainting algorithm.

A new interpretation of multifrequency/multipolarization radar signatures of the Gulf Stream front
, 1999 Radar signatures which are observed on SIR-C/X-SAR multifrequency/multipolarization synthetic aperture radar images of the Gulf Stream off the U.S. east coast are compared with results of simulations with a numerical radar imaging model. Based on in situ

Feature-Guided SAR-to-Optical Image Translation
IEEE Access, 2020 The powerful performance of Generative Adversarial Networks (GANs) in image-to-image translation has been well demonstrated in recent years. However, most methods are focused on completing an isolated image translation task.
