Compared with the traditional holographic technology, metasurface holography is a promising technology due to the large field angle and high spatial resolution. Thanks to the precise control of phase, amplitude, polarization and so on, metasurface holography provides a flexible platform for light modulation, optical encryption and so on. Besides, the process of image reconstruction by single pixel...
Nanotherapeutics for Spinal Cord Injury
In article number 2102102, Zhizhong Li, Tianfeng Chen, and co‐workers design a polymer‐based nano drug delivery system conjugating with MMPs‐responsive molecule to target the injury site, regulate the polarization of macrophages and exert neuroprotective effects to promote locomotor recovery.
Neuroinflammation is critically involved in the repair of spinal cord injury (SCI), and macrophages associated with inflammation propel the degeneration or recovery in the pathological process. Currently, efforts have been focused on obtaining efficient therapeutic anti‐inflammatory drugs to treat SCI. However, these drugs are still unable to penetrate the blood spinal cord barrier and lack the ability...
This paper demonstrates the ability of a CuCo2S4–reduced graphene oxide (rGO) composite to perform robust electrochemical performances applying to supercapacitors (SCs) and lithium ion batteries (LIBs). The first‐principle calculation based on density functional theory is conducted to study the electronic property of CuCo2O4 and CuCo2S4 and provide a theoretical basis for this work. Then, the 3D spinel‐structured...
Minimally invasive therapies avoiding surgical complexities evoke great interest in developing injectable biomedical devices. Herein, a versatile approach is reported for engineering injectable and biomimetic nanofiber microspheres (NMs) with tunable sizes, predesigned structures, and desired compositions via gas bubble–mediated coaxial electrospraying. The sizes and structures of NMs are controlled...
In article number 1907393, Jingwei Xie and co‐workers report a simple yet versatile approach for engineering injectable and biomimetic nanofiber microspheres (NMs) with tunable sizes, predesigned structures, and desired composition via gas bubble‐mediated co‐axial electrospraying. Such a novel class of NMs holds great potential for many biomedical applications such as tissue filling, cell and drug...
In article number 1800423, Ling Li, Ze Yu, Lin Gu, and co‐workers use ZIF‐8/ZIF‐67 with electrospinning to successfully fabricate Co‐Nx‐embedded 1D porous carbon nanofibers. The unique 1D structure, such as higher graphitization degree beneficial, hierarchical porosity, and highly dispersed CoNxC active sites, is beneficial for highly efficient electrochemical performance for oxygen reduction and...
Herein, an approach is reported for fabrication of Co‐Nx‐embedded 1D porous carbon nanofibers (CNFs) with graphitic carbon‐encased Co nanoparticles originated from metal–organic frameworks (MOFs), which is further explored as a bifunctional electrocatalyst for both oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Electrochemical results reveal that the electrocatalyst prepared...
