Cu─X Bonds Regulated Conduction and Polarization Loss in Conductive Metal‐Organic Framework Under Electromagnetic Field

open access: yesAdvanced Science, EarlyView.
A ligand regulation strategy by modifying functional motifs (X = −NH2, −OH, and −SH) in triphenylene is pioneered and developed to afford Cu─X bonds, achieving a synergistic conduction and polarisation loss mechanism under an electromagnetic field for enhanced electromagnetic wave absorption. Abstract Conduction and polarization are known to profoundly

Wide area coverage radar imaging satellite for earth applications [PDF]

open access: yes
A preliminary study was made of a radar imaging satellite for earth applications. A side-looking synthetic-aperture radar was considered and the feasibility of obtaining a wide area coverage to reduce the time required to image a given area was ...

Decoupling Membrane Electrode Assembly Materials Complexity from Fuel Cell Performance through Image‐Based Multiphase and Multiphysics Modelling

open access: yesAdvanced Energy Materials, EarlyView.
A high‐resolution image‐based multiphase and multi‐physics modelling framework is developed to decouple structural changes in the membrane electrode assemblies of high‐temperature proton exchange membrane fuel cells. These changes are then digitally combined to show how morphological defects such as membrane pores, catalyst cracks, and phase migration ...

Enabling High‐Voltage Polymer‐Based Solid‐State Batteries Through Reinforcements with LiAlO2 Fillers

open access: yesAdvanced Energy Materials, EarlyView.
Polymer‐ceramic solid composite electrolytes with passive LiAlO2 fillers show remarkable improvements in Li‐ion conductivity in polycarbonates as compared to both non‐conductive Al2O3 and conductive Li7La3Zr2O12 counterparts. The exceptionally high transference numbers contribute to reversible and stable electrochemistry with Li‐metal electrodes and to

Essential lipid autacoids rewire mitochondrial energy efficiency in metabolic dysfunction‐associated fatty liver disease

open access: yesHepatology, EarlyView., 2022
Increased liver content of DHA‐derived small lipid autacoids (i.e resolvin D1 and maresin 1) associates with enhanced mitochondrial oxidative phosphorylation, fatty acid β‐oxidation and bioenergetic metabolic flux. These features provide hepatic protection from steatotic, pro‐inflammatory and fibrogenic insults.

Novel Zwitterionic Polyurethane‐in‐Salt Electrolytes with High Ion Conductivity, Elasticity, and Adhesion for High‐Performance Solid‐State Lithium Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A novel zwitterionic polyurethane‐in‐salt electrolyte (zPU‐SPE) is developed, achieving high ionic conductivity (3.7 × 10⁻⁴ S cm−1 at 25 °C), superior adhesion to lithium metal, and exceptional elasticity. This innovative electrolyte enables stable solid‐state lithium metal batteries, demonstrating excellent cycling stability, strong interfacial ...

Radar response from vegetation with nodal structure [PDF]

open access: yes
Radar images from the SEASAT synthetic aperture radar (SAR) produced unusually high returns from corn and sorghum fields, which seem to indicate a correlation between nodal separation in the stalk and the wavelength of the radar.
