In article number 1603423, He Tian, Jianbo Wu, Hui Zhang, and co‐workers develop a thermodynamically controlled method for the epitaxial growth of atomically layered Pt shells on icosahedral, octahedral, and cubic Pd seeds, with Pd‐Pt core‐shell icosahedra being the best electrocatalysts for oxygen reduction reaction. The cover image shows that most of Pt shells in the icosahedra are dominated by...
The significance of bionanomotors in nanotechnology is analogous to mechanical motors in daily life. Here the principle and approach for designing and constructing biomimetic nanomotors with continuous single‐directional motion are reported. This bionanomotor is composed of a dodecameric protein channel, a six‐pRNA ring, and an ATPase hexamer. Based on recent elucidations of the one‐way revolving...
Exocytosis of single‐walled carbon nanotubes (SWCNTs) determines therapeutic efficiency and toxicity of nanoproducts but its underlying mechanism remains elusive. In this study, it is found that the exocytosis mechanism of SWCNTs is mediated mainly through the activation of P2X7 receptor (P2X7R), an ATP‐gated membrane receptor highly expressed in macrophages. Inhibition of P2X7R signaling by either...
The exocytosis and underlying mechanism of single‐walled carbon nanotubes (SWCNTs) in macrophages is revealed by B. Wan, L.‐H. Guo, and co‐workers on page 5998. Exocytosis of SWCNTs is initiated by the activation of the P2X7 receptor, which accounts for the lysosomal secretion pathway as a potential mechanism for cells to repel SWCNTs. The cover image shows microtubules providing orbits for the exocytosis...
Designing smart surfaces with tunable wettability has drawn much attention in recent years for academic research and practical applications. Most of the previous methods to achieve such surfaces demand some particular materials that inherently have special features or complicated structures which are usually not easy to obtain. A novel strategy to achieve such smart surfaces is proposed by using the...
Monolayer MoS2 is synthesized on hexagonal boron nitride (h‐BN) flakes with a simple, high‐yield method. Monolayer MoS2 on h‐BN exhibits improved optical quality. Combining the theoretical and experimental analysis, it is concluded that the enhanced photoluminescence and Raman intensities of monolayer MoS2 probably originate from the relatively weak doping effect from the h‐BN substrate rather than...
