The fabrication of discrete nanostructures with both plasmonic circular dichroism (PCD) and chiral features is still a challenge. Here, gold nanoarrows (GNAs) with both chiroptical responses and chiral morphologies are achieved by using L‐selenocystine (L‐SeCys2) as a chiral inducer. While L‐SeCys2 generates GNAs with a weak PCD signal, the irradiated L‐SeCys2 (irr‐L‐SeCys2) leads to GNAs with featured...
Powering device for miniaturized electronics is highly desired with well‐maintained capacity and high‐rate performance. Though Ni–Zn microbattery can meet the demand to some extent with intrinsic fast kinetic, it still suffers irreversible structure degradation due to the repeated lattice strain. Herein, a stable Ni–Zn microbattery with ultrahigh‐rate performance is rationally constructed through...
Exploiting platinum‐group‐metal (PGM)‐free electrocatalysts with remarkable activity and stability toward oxygen reduction reaction (ORR) is of significant importance to the large‐scale commercialization of proton exchange membrane fuel cells (PEMFCs). Here, a high‐performance and anti‐Fenton reaction cobalt–nitrogen–carbon (Co–N–C) catalyst is reported via employing double crosslinking (DC) hydrogel...
In article number 2003251, Liang He, Wen Luo, and co‐workers introduce and review the recent progress of microbatteries from the view of construction and application. The serviceability and connection about technique fundamentals, device design and practical applications are discussed. Throughout the Review, the application‐oriented perspective on the current challenges and further research directions...
High‐performance miniaturized energy storage devices have developed rapidly in recent years. Different from conventional energy storage devices, microbatteries assume the main responsibility for micropower supply, functionalization, and characterization platforms. Evolving from the essential goals for battery design of high power density, high energy density, and long lifetime, further practical demands...
Highly efficient and stable bifunctional electrocatalysts for oxygen reduction and evolution are essential for aqueous rechargeable Zn–air batteries, which require highly active sites as well as delicate structural design for increasing effective active sites and facilitating mass/electron transfer. Herein, a scalable and facile self‐catalyzed growth strategy is developed to integrate highly active...
Electroless deposition via a spontaneous redox reaction between the metal precursor and support is believed to be a promising approach for the syntheses of supported metal nanoparticles (SMNPs). However, its widespread applications are significantly prohibited by the low reductivity and high cost of support. To overcome these shortcomings, a porous carbon (PC) is herein developed as a promising matrix...
The synthesis and surface modification of gold nanorods (GNRs) is one of the most important and basic issues in nanoscience. Most of the widely investigated GNRs are coated with a cetyltrimethylammonium bromide(CTAB) bilayer. Here, a highly efficient method is proposed to replace CTAB from the surface of GNRs with a bifunctional 11‐mercaptoundecanoic acid in order to decrease the possible toxicity...
