Multi‐Wavelength Achromatic 3D Meta‐holography with Zoom Function

open access: yesAdvanced Science, EarlyView.
Due to the wavelength mismatch, chromatic aberrations are inevitable in multi‐wavelength meta‐holography. Moreover, since the meta‐hologram is difficult to be refreshed, zoom meta‐holography has not been reported to date. This study proposes a multi‐wavelength achromatic 3D meta‐holography with a zoom function, breaking through both the chromatic ...

Secondary Electron Hyperspectral Imaging of Carbons: New Insights and Good Practice Guide

open access: yesAdvanced Science, EarlyView.
Secondary hyperspectral imaging of carbon surfaces is assessed with reference materials and in comparison to standard spectroscopies. Characterization of functional carbon materials from battery research reveals otherwise inaccessible information about the distribution of sp2 and amorphous carbon, as shown in graphite anode and carbon coated lithium ...

A Soft‐Soft Contact Triboelectric Nanogenerator with a Ternary Four‐Phase Structure for Self‐Powered High‐Efficiency Dust Removal on Mars

open access: yesAdvanced Science, EarlyView.
The frequent dust storms and charged dust particles on Mars pose significant challenges to the power generation efficiency and service life of solar panels during exploration missions. This paper proposes a novel wind‐driven ternary four‐phase soft‐soft contact triboelectric nanogenerator (FPS‐TENG) for dust removal.

Mechanical Metamaterial‐Based Structure with Magnetically Controlled Nonreversibility and Nonreciprocity for Programmable Locomotion

open access: yesAdvanced Science, EarlyView.
A magneto‐mechanical metamaterial‐based structure that simultaneously exhibits programmable nonreversibility and nonreciprocity. These cause substantial transitions in static mechanical properties, such as Poisson's ratio and stiffness, leading to stark changes in energy absorption.

A Myelin Debris Cleaner for Spinal Cord Injury Recovery: Polycaprolactone / Cell Membrane Assembled Scaffolds

open access: yesAdvanced Science, EarlyView.
pMM‐PCL, made up of pretreated macrophage menbrane and polycaprolactone, boasts the adsorption of harmful myelin debris in the microenvironment of spinal cord injury. Abstract After spinal cord injury (SCI), a mass of myelin debris derived from injured myelin sheath will be consistently generated and induce macrophages to be foam cells.
