The recent groundbreaking achievement in the synthesis of large‐sized single crystal C60 monolayer, which is covalently bonded in a plane using C60 as building blocks. The asymmetric lattice structure endows it with anisotropic phonon modes and conductivity. If these C60 are arranged in form of 1D fiber, the improved manipulation of phonon conduction along the fiber axis could be anticipated. Here,...
Over the past decades, significant advances have been made in lithium‐ion batteries. However, further requirement on the electrochemical performance is still a powerful motivator to improve battery technology. The solid electrolyte interphase (SEI) is considered as a key component on negative electrode, having been proven to be crucial for the performance, even in safety of batteries. Although numerous...
Solution‐processed photodetectors have emerged as promising candidates for next‐generation of visible‐near infrared (vis–NIR) photodetectors. This is attributed to their ease of processing, compatibility with flexible substrates, and the ability to tune their detection properties by integrating complementary photoresponsive semiconductors. However, the limited performance continues to hinder their...
Recently, sodium‐ion batteries (SIBs) have received considerable attention for large‐scale energy storage applications. However, the low initial Coulombic efficiency of traditional SIBs severely impedes their further development. Here, a highly active Na2S‐based composite is employed as a self‐sacrificial additive for sodium compensation in SIBs. The in situ synthesized Na2S is wrapped in a carbon...
Dion‐Jacobson perovskite (DJP) films suffer from the high structural disorder and non‐compact morphology, leading to inefficient and unstable solar cells (SCs). Here, how the alkyl chains of alkylammonium pseudohalide additives including methylammonium thiocyanate (MASCN) and ethylammonium thiocyanate (EASCN), and propylammonium thiocyanate (PASCN), impact the microstructures, optoelectronic properties...
The construction of commercial surface enhanced Raman scattering (SERS) sensors suitable for clinical applications is a pending problem, which is heavily limited by the low production of high‐performance SERS bases, because they usually require fine or complicated micro/nano structures. To solve this issue, herein, a promising mass‐productive 4‐inch ultrasensitive SERS substrate available for early...
The lithium–sulfur (Li–S) battery is considered as one of the most promising options because the redox couple has almost the highest theoretical specific energy (2600 Wh kg−1) among all solid anode‐cathode candidates for rechargeable batteries. The “solid–liquid–solid” mechanism has become a dominating phase transformation process since it was first reported, although this cathode mode suffers from...
Developing dynamic and highly sensitive methods for imaging M2‐type tumor‐associated macrophages (TAMs) is vital for monitoring the tumor progression and assessing the therapeutic efficacy. Here, the fabrication and application of rationally designed Er‐based rare‐earth nanoprobes for the targeted imaging of M2‐type TAMs in glioblastoma (GBM) through the second near‐infrared (NIR‐II) fluorescence...
Aqueous zinc (Zn) metal batteries have been regarded as the most promising aqueous batteries due to their low redox potential, high theoretical capacity, and abundant Zn resources. Unfortunately, Zn dendrite growth and serious side reactions drastically curtail the cycle life, severely affecting their large‐scale application. Herein, a multifunctional ordered Zn‐aminotrimethylene phosphonic acid (Zn‐ATMP)...
Radical‐containing frameworks (RCFs) have emerged as promising functional materials in various fields due to the combination of the highly ordered frame structure and the fascinating property of organic radicals. Here, the first example of radical‐containing supramolecular organic frameworks (SOFs) fabricated by the chaotropic effect between closo‐dodecaborate cluster (B12H122−) and 2,4,6‐tri(4‐pyridyl)‐1,3,5‐triazine...
Metal single atom catalysts (SAC) have been successfully used in heterogeneous catalysis but developing a scalable and economic support for SAC is still a great challenge. Here, cyclized polyacrylonitrile (CPAN) is proposed as a promising support for single atom metal catalysts. CPAN can be easily prepared from cheap industrial product polyacrylonitrile (PAN), which has excellent processability. A...
