Previous programmable metasurfaces integrated with diodes or varactors require external instructions for field programmable gate arrays (FPGAs), which usually rely on computer‐inputs or pre‐loaded algorithms. But the complicated external devices make the coding regulation process of the programmable metasurfaces cumbersome and difficult to use. To simplify the process and provide a new interaction...
Sustainable production of hydrogen from seawater electrolysis has attracted much attention in recent years. Considering that Cl‐ might corrode metal substrate by crossing through the covered catalyst, the conventional Ni(II)Fe(III)‐layered double hydroxide (NiFe‐LDH) loaded on metal substrate, as a favorable oxygen evolution catalyst, cannot be directly used for seawater electrolysis. Herein, an anti‐corrosion...
Brain‐inspired neuromorphic computing hardware based on artificial synapses offers efficient solutions to perform computational tasks. However, the nonlinearity and asymmetry of synaptic weight updates in reported artificial synapses have impeded achieving high accuracy in neural networks. Here, this work develops a synaptic memtransistor based on polarization switching in a two‐dimensional (2D) ferroelectric...
Cardiac microphysiological systems are accurate in vitro platforms that reveal the biological mechanisms underlying cardiopathy, accelerating pharmaceutical research in this field. Current cardiac microphysiological devices and organs‐on‐chips consist of several layers prepared with complex, multi‐step processes. Incorporating inorganic photonic crystals may cause long‐term biocompatibility issues...
Electromagnetic Manipulation and Encryption
To simplify the process and provide a new interaction manner, Lei Chen, Tie Jun Cui, and co‐workers propose a touch‐programmable metasurface (TPM) based on touch sensing modules to realize various electromagnetic (EM) manipulations and encryptions, in article number 2203871. Through the touch controls, TPM can achieve independent and direct manipulation...

In article number 2202235, Chunyu Chang, Donghui Zhang, and co‐workers develop micropatterned hydrogels with anisotropic structural colors by locking shear‐oriented tunicate cellulose nanocrystals (TCNCs) in hydrogel networks through in situ polymerization. The autonomous beating of cardiomyocytes drives synchronous deformations of the micropatterned hydrogels, causing periodic...
Phosphate for Corrosion Resistance
In article number 2203852, Jie Sun and co‐workers demonstrate that PO43− intercalation in Ni(II)Fe(III)‐layered double hydroxide (NiFe‐LDH) can prevent the Ni substrate from Cl− corrosion by electrostatic repulsion. The anode stability time of seawater electrolysis can be improved more than 100 times by the intercalated PO43−.
Blood–Brain Barrier Therapy
The blood–brain barrier (BBB) is a bottleneck in the treatment of brain tumors. In article number 2203678, Liang Wang, Yinyan Wang, Lin Feng, and co‐workers summarize the current approaches to overcome the BBB, such as the use of “Trojan horse” molecular modifications for deception, and describe a variety of micro‐nanocarriers for targeted brain tumor therapy.
A dielectric core–metal shell nanosphere has attracted scientific and technological interests due to the unique optical resonances arising from the hybridization of surface plasmon modes and cavity modes. The previous studies focus on a low‐index dielectric core without its own optical resonances. Here, optical resonances of a core–shell nanosphere with a high refractive index (n ≈ 4) core with the...
Sodium‐ion batteries (SIBs) have attracted wide interest for energy storage because of the sufficient sodium element reserve on the earth; however, the electrochemical performance of SIBs cannot achieve the requirements so far, especially, the limitation of cathode materials. Here, a kilogram‐scale route to synthesize Na2FePO4F/carbon/multi‐walled carbon nanotubes microspheres (NFPF@C@MCNTs) composite...
Interface modulation of nickel phosphide (Ni2P) to produce an optimal catalytic activation barrier has been considered a promising approach to enhance the hydrogen production activity via water splitting.

The in‐depth study of the interplay and cooperation between multiple organelles is an important biological task. Single fluorescent probes for separate visualization of multiple organelles is a desirable molecular tool, but the construction of such a probe is extremely difficult owing to the lack of valid strategies. In this work, utilizing the reversible cyclization reaction and intermolecular π...
Rationally designing on sundry multiphase compounds has come into the spotlight for sodium‐ion batteries (SIBs) due to enhanced structural stability and improved electrochemical performances. Nevertheless, there is still a lack of thorough understanding of the reaction mechanism of high‐active phase boundaries existing between multiphase compounds.

Stimulated surface‐enhanced Raman scattering (SERS) in combination with engineered nano‐tracer offers extraordinary potential in lateral flow immunoassays (LFIAs). Nonetheless, the investigation execution of SERS‐LFIA is often compromised by the intricacy and overlap of the Raman fingerprint spectrum as well as the affinity‐interference of nano‐tracer to antibody. To circumvent these critical issues,...
Vacuum vapor deposition (VVD) is a promising way to advancing the commercialization of perovskite light sources owing to its convenience for wafer‐scale mass production and compatibility with silicon photonics manufacturing infrastructure. However, the light emission performance of VVD‐grown perovskites still lags far behind that of the conventional solution‐processed counterparts due to their inferior...
Emerging directions in the growing wearable electronics market have spurred the development of flexible energy storage systems that require deformability while maintaining electrochemical performance. However, the traditional fabrication approaches of lithium‐ion batteries (LIBs) are challenging to withstand long‐cycle bending alternating loads due to the stress concentration caused by the nonuniformity...
Multicellular systems, such as microbial biofilms and cancerous tumors, feature complex biological activities coordinated by cellular interactions mediated via different signaling and regulatory pathways, which are intrinsically heterogeneous, dynamic, and adaptive. However, due to their invasiveness or their inability to interface with native cellular networks, standard bioanalysis methods do not...
