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...
Monolithic integration of nanostructured metalenses with broadband light transmission and good charge transport can simultaneously enhance the sensitivity, speed, and efficiency of photodetectors. The realization of built‐in broadband metalenses in perovskite photodetectors, however, has been largely challenged by the limited choice of materials and the difficulty in nanofabrication. Here a new type...
Metal‐phenolic networks (MPNs) are an emerging class of supramolecular surface modifiers with potential use in various fields including drug delivery. Here, the development of a unique MPN‐integrated core‐satellite nanosystem (CS‐NS) is reported. The “core” component of CS‐NS comprises a liposome loaded with EDTA (a metal ion chelator) in the aqueous core and DiR (a near‐infrared photothermal transducer)...
Electron transporting layers (ETLs), required to be optically transparent in perovskite solar cells (PSCs) having regular structures, possess a determinant effect on electron extraction and collection. Metal oxides (e.g., TiO2) have overwhelmingly served as ETLs, but usually have low electron mobility (μe < 10−2 cm2 V−1 s−1) not favorable for photovoltaic conversion. Here, metal oxides are replaced...
Prevention and intervention methods are urgently needed to curb the global pandemic of coronavirus disease‐19 caused by severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2). Herein, a general pro‐antigen strategy for subunit vaccine development based on the reversibly formulated receptor binding domain of SARS‐CoV‐2 spike protein (S‐RBD) is reported. Since the poor lymph node targeting and...
Bulk metals lack chirality. Recently, metals have been sculptured with metastable chirality varying from the micro‐ to nano‐scale. The manipulation of molecular chirality could be novelly performed using metals composed of chiral lattices at atomic scales (i.e., chiral nanoparticles or CNPs) if one could fundamentally understand the interactions between molecules and the chiral metal lattices. The...
In article number 2001473, Zhifeng Huang and co‐workers introduce an emerging concept of metal chiral nanoparticles (CNPs), composed of chiral lattices at the atomic scale without containing chiral ligands. Metal CNPs are mainly generated by macroscopic shear forces applied with glancing angle deposition, and have unique asymmetric properties promisingly leading to prominent applications in the fields...
