The charge transfer within heterojunction is crucial for the efficiency and stability of photocatalyst for overall water splitting (OWS). Herein, InVO4 nanosheets have been employed as a support for the lateral epitaxial growth of ZnIn2S4 nanosheets to produce hierarchical InVO4@ZnIn2S4 (InVZ) heterojunctions. The distinct branching heterostructure facilitates active site exposure and mass transfer,...
Smart modulation of bioelectric signals is of great significance for the development of brain‐computer interfaces, bio‐computers, and other technologies. The regulation and transmission of bioelectrical signals are realized through the synergistic action of various ion channels in organisms. The bionic nanochannels, which have similar physiological working environment and ion rectification as their...
Many materials with nanofluidic channels are exploited to achieve salinity gradient energy conversion. However, most materials are fragile, difficult to process, or only prepared into a limited size, which greatly restricts their practical application in the future. Herein, a covalent organic polymers membrane with high mechanical property and stability is fabricated, which can keep integrity in harsh...
Energy Harvesting
There are salinity gradients at the confluence of the river and sea, which contain tremendous amounts of energy. In article number 2107600, Jin Zhai and co‐workers fabricate a covalent organic polymers membrane for harvesting the salinity gradient energy. The membrane has better properties and can be prepared in large areas, which is expected to be applied in the future to real‐world...
Ion storage structure widely exists in organisms, which is used to harvesting energy in environment and converting it into ion concentration gradient to maintain complex life activities. The construction of ion storage structures relies on isolating the biological body fluids by biofilm systems, which can also be regarded as local ions confinement. Mimicking this ions storage process, an “ion pool”...
A platinum network‐based transparent electrode has been fabricated by electrospinning. The unique nanobelt structured electrode demonstrates low sheet resistance (about 16 Ω sq−1) and high transparency of 80% and excellent flexibility. One of the most interesting demonstrations of this Pt nanobelt electrode is its excellent reversibly resilient characteristic. The electric conductivity of the flexible...
