Magnetically Controlled Reversible Photomagnetic Nanoactuators for Dynamic Contrast Enhancement in Optical Coherence Tomography

Advanced Materials, EarlyView.
Photomagnetic nanoactuators with ≈90% scattering efficiency in the second near‐infrared window are demonstrated to exhibit magnetic field‐controlled modulation of optical scattering and optical coherence tomography signals. These nanoactuators are reversibly assembled and disassembled under the external magnetic field modulation, enabling enhanced ...

Quality Assessment of SAR-to-Optical Image Translation

Remote Sensing, 2020
Synthetic aperture radar (SAR) images contain severe speckle noise and weak texture, which are unsuitable for visual interpretation. Many studies have been undertaken so far toward exploring the use of SAR-to-optical image translation to obtain near ...

LPI‐based cooperative tactic for satellite communication uplink signal accompanied by directed and power limited jamming

IET Signal Processing, 2022
To protect the satellite communication uplink signal (SCUS) from being intercepted by an eavesdropper, this study proposes several tactics to ensure SCUS being in the low probability of intercept (LPI) state.

Covalent Surface Modification of Hydrophobic Alkoxides on Ti3C2Tx MXene Nanosheets Toward Amphiphilic and Electrically Conductive Inks

Advanced Materials, EarlyView.
Electrically conductive and amphiphilic MXene inks are achieved by surface modification of sodium alkoxides, where surface‐modified MXenes are dispersible both in water and in non‐polar solvents such as toluene. Alkoxide‐functionalized MXenes also show enhanced environmental stability compared to pristine MXene, leading to higher electrical ...
