Bi2Te3‐based alloys are the benchmark for commercial thermoelectric (TE) materials, the widespread demand for low‐grade waste heat recovery and solid‐state refrigeration makes it imperative to enhance the figure‐of‐merits. In this study, high‐performance Bi0.5Sb1.5Te3 (BST) is realized by incorporating Cu2GeSe3 and Se. Concretely, the diffusion of Cu and Ge atoms optimizes the hole concentration and...
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...
Changes in atomic bonding configuration in carbon from sp3 to sp2 are known to exist in certain structural defects in diamond, such as twin boundaries, grain boundaries, and dislocations, which have a significant impact on many properties of diamond.

Stimulating electron transitions and promoting exciton dissociation are crucial for improving the photocatalytic performance of polymeric carbon nitride (CN) yet still challenging. Herein, a novel CN with C dopant and asymmetric structure (CC‐UCN2) is ingeniously synthesized. The obtained CC‐UCN2 not only reinforces the intrinsic π→π* electron transitions, but also successfully awakens additional...
clustered regularly interspaced short palindromic repeats (CRISPR)‐Cas systems are increasingly used in biosensor development. However, directly translating recognition events for non‐nucleic acid targets by CRISPR into effective measurable signals represents an important ongoing challenge. Herein, it is hypothesized and confirmed that CRISPR RNAs (crRNAs) in a circular topology efficiently render...
The tumor microenvironment typically possesses immunosuppressive properties that hinder the effectiveness of antitumor immune responses, even in the context of immunotherapies. However, it is observed that pathogenic microorganisms can trigger strong immune responses during infection, offering a potential means to counteract the immunosuppressive environment of tumors. In this study, a protein nanocage...
