Lithium–Sulfur Batteries
In article number 2304210, Dequan Liu, Saikat Das, Deyan He, Yuichi Negishi, and co‐workers use Au24Pt(PET)18 nanoclusters for the first time as electrocatalysts in sulfur reduction reaction. The authors construct a lithium–sulfur battery with Au24Pt(PET)18@Graphene(G)‐based separator that demonstrates excellent capacity and long cycling stability, besides arresting the shuttling...
Due to their high designability, unique geometric and electronic structures, and surface coordination chemistry, atomically precise metal nanoclusters are an emerging class of functional nanomaterials at the forefront of materials research. However, the current research on metal nanoclusters is mainly fundamental, and their practical applications are still uncharted. The surface binding properties...
Traditional chemo‐immunotherapy can elicit T cell immune response by inducing immunogenic cell death (ICD), however, insufficient ICD limits the lasting antitumor immunotherapeutic efficacy. Herein, tadpole–ovoid manganese‐doped hollow mesoporous silica coated gold nanoparticles (Au@HMnMSNs) as biodegradable catalytic cascade nanoreactors are constructed to generate intratumoral high‐toxic hydroxyl...
A method for the solidification of metallic alloys involving spiral self‐organization is presented as a new strategy for producing large‐area chiral patterns with emergent structural and optical properties, with attention to the underlying mechanism and dynamics. This study reports the discovery of a new growth mode for metastable, two‐phase spiral patterns from a liquid metal. Crystallization proceeds...
In article number 1906146, Robert O. Ritchie, Ashwin J. Shahani, and co‐workers investigate the origins of certain eutectics that grow into spiral geometry. The spiral formation follows a two‐step process, wherein the first step is mediated by the low solid–liquid interfacial energy of a precursor phase, and the second step by crystallographic defects on the precursor. The cover features a computed...
Lithium–sulfur batteries (LSBs) have shown great potential for application in high‐density energy storage systems. However, the performance of LSBs is hindered by the shuttle effect and sluggish reaction kinetics of lithium polysulfides (LiPSs). Herein, heterostructual Nb2O5 nanocrystals/reduced graphene oxide (Nb2O5/RGO) composites are introduced into LSBs through separator modification for boosting...
The asymmetrical features and unique properties of multibuilding block Janus nanostructures (JNSs) provide superior functions for biomedical applications. However, their production process is very challenging. This problem has hampered the progress of JNS research and the exploration of their applications. In this study, an asymmetrical multibuilding block gold/iron oxide JNS has been generated to...
