Single-Shot Compressive Multiple-Inputs Multiple-Outputs Radar Imaging Using a Two-Port Passive Device

IEEE Access, 2016
This paper presents a compressive technique that simplifies the architecture of multiple-input multiple-output (MIMO) radar imaging systems. By means of a passive device connected to an MIMO array of antennae, a novel approach is introduced to extract ...

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 ...

Multiple feature-enhanced synthetic aperture radar imaging [PDF]

, 2009
Non-quadratic regularization based image formation is a recently proposed framework for feature-enhanced radar imaging. Specific image formation techniques in this framework have so far focused on enhancing one type of feature, such as strong point ...

Detecting Cr6+ at ≈100 pM Concentration with Fluorescence Enhancement Signatures in a Novel Eco‐Fluorophore: Matching WHO's 96 pM Recommended Standard for Drinking Water

Advanced Materials, EarlyView.
Through a dual‐functionalization strategy, carbon quantum dots (CQD) with exceptional fluorescence properties are engineered. These CQD are integrated with graphitic carbon nitride to form a 2D/2D heterostructure via both covalent and non‐covalent modification.

Synergistic Cathode‐Electrolyte Engineering for Enhanced Longevity in Li‐S Batteries

Advanced Materials, EarlyView.
Thanks to the synergism of abundant active sites and the superior catalytic effect of the uf‐MBene/CNT cathode host, along with uniform lithium ion deposition facilitated by adding Na2SeO3 additives, the cell with this S@uf‐MBene/CNT cathode and Na2SeO3 additive can maintain stable cycling for up to 850 cycles with a capacity retention rate of 93.6% at

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 ...

Rational Development of a Novel Emulgel Adjuvant for Single‐Shot Effective Vaccination: A Multivariate Analysis Approach

Advanced Materials, EarlyView.
Using multivariate analysis, a novel emulgel adjuvant is developed by combining key nanoemulsion formulation variables–hydrogel trapping, small globule size, and mannide monooleate surfactant–achieving 10× greater immunogenicity than MF59 in mice after a single shot.
