The development of flexible microelectronic systems requires the construction of high‐energy‐output planar micro‐supercapacitors (MSCs). Herein, the localized electron density, by introducing graphene quantum dots (GQDs) on the surface of electrodes, is regulated. The enhanced local field intensity promotes ion electrostatic adsorption at the solid–liquid interface, which significantly improves the...
Scanning Tunneling Microscopy/Spectroscopy
In article number 2300413, Shern‐Long Lee and co‐workers summarize recent scanning tunneling microscopy/spectroscopy (STM/STS) studies of 3D nanoarchitectures based on the supramolecular assembly of functionalized molecules at the liquid‐solid interface. The authors highlight several molecular systems with an emphasis on unique characteristics and electronic...
Exploring supramolecular architectures at surfaces plays an increasingly important role in contemporary science, especially for molecular electronics. A paradigm of research interest in this context is shifting from 2D to 3D that is expanding from monolayer, bilayers, to multilayers. Taking advantage of its high‐resolution insight into monolayers and a few layers, scanning tunneling microscopy/spectroscopy...
With rapid and continuous consumption of nonrenewable energy, solar energy can be utilized to meet the energy requirement and mitigate environmental issues in the future. To attain a sustainable society with an energy mix predominately dependent on solar energy, photoelectrochemical (PEC) device, in which semiconductor nanostructure‐based photocatalysts play important roles, is considered to be one...
Sodium‐ion batteries (SIBs) are considered as a promising large‐scale energy storage system owing to the abundant and low‐cost sodium resources. However, their practical application still needs to overcome some problems like slow redox kinetics and poor capacity retention rate. Here, a high‐performance ZnSe/carbon fibers (ZnSe‐CFs) anode is demonstrated with high electrons/Na+ transport efficiency...
With the development of miniaturization, lightweight and integration of electronic devices, the demand for high‐temperature dielectric capacitors is becoming urgent. Nevertheless, the breakdown strength and polarization are deteriorated at high temperatures due to the thermal energy assisting the electron transport and impeding the dipole alignment. Here, a structure of capacitor with double gradients...

DNA hydrogels have been demonstrated as versatile potential adsorbents, immobilization carriers of bioactive molecules, catalysts, sensors, etc. Moreover, altering...
The diverse biological effects of nanomaterials form the basis for their applications in biomedicine but also cause safety issues. Induction of autophagy is a cellular response after nanoparticles exposure. It may be beneficial in some circumstances, yet autophagy‐mediated toxicity raises an alarming concern. Previously, it has been reported that upconversion nanoparticles (UCNs) elicit liver damage,...
Carbon nanofibers (CNFs) bearing oxygen‐containing functional groups and inhomogeneous nanopores are successfully prepared by excimer UV radiation, as presented by Y. Hu and co‐workers on page 5269. The CNFs demonstrate potential for use as an anodic material in rechargeable Li‐ion batteries. Their improved electrochemical performances are attributed to the chemically bonded solid‐electrolyte interface...
Carbon nanofibers (CNFs) bearing oxygen‐containing functional groups and inhomogeneous nanopores are successfully prepared by excimer UV radiation. The CNFs demonstrate potential for use as an anodic material in rechargeable Li‐ion batteries. Their improved electrochemical performances are attributed to the chemically bonded solid–electrolyte interface films on the CNF surface. This approach is also...
