Acoustic Coding Metasurfaces
In article number 2308349, Hao‐Wen Dong and co‐workers employ topology optimization techniques to design a 3‐bit broadband acoustic coding metasurface. With the 3‐bit coding units, a broadband acoustic vortex metasurface is established. Within the target frequency domain, it can modulate reflected acoustic waves into vortex waves. Combined with convolution methods, we...
The acoustic coding metasurfaces (ACMs) have the ability to manipulate complex acoustic behavior by reconstructing the coding sequence. In particular, the design of broadband coding enhances the versatility of ACMs. ACMs offer significant advantages over traditional metasurfaces, including a limited number of units and flexible wave control performance. The unit quantity is determined by 2n, with...
Hole‐transporting layers (HTLs) play a crucial role in the performance of inverted, p‐i‐n perovskite solar cells (PSCs). Chlorophylls (Chls) are naturally abundant organic photoconductors on earth, with good charge carrier mobility and appropriate Fermi energy levels that make them promising candidates for use in photovoltaic devices. However, Chls films prepared using the solution method exhibit...
Multifunctional electrocatalysts are crucial to cost‐effective electrochemical energy conversion and storage systems requiring mutual enhancement of disparate reactions. Embedding noble metal nanoparticles in 2D metal–organic frameworks (MOFs) are proposed as an effective strategy, however, the hybrids usually suffer from poor electrochemical performance and electrical conductivity in operating conditions...
Gossypol is a chemotherapeutic drug that can inhibit the anti‐apoptotic protein Bcl‐2, but the existing gossypol‐related nanocarriers cannot well solve the problem of chemotherapy resistance. Based on the observation that gossypol becomes black upon Fe3+ coordination, it is hypothesized that encasing gossypol in glyceryl monooleate (GMO) and making it coordinate cobalt ferrite will not only improve...
Effectively interfering energy metabolism in tumor cells and simultaneously activating the in vivo immune system to perform immune attacks are meaningful for tumor treatment. However, precisely targeted therapy is still a huge challenge. Herein, a mitochondrial‐targeting phototheranostic system, FE‐T nanoparticles (FE‐T NPs) are developed to damage mitochondria in tumor cells and change the tumor...
