Normally, only noncentrosymmetric structure of the materials can potentially be piezoelectric. Thus, it is limited in the field of piezoelectricity for the centrosymmetric structure of the material. In this work, the performance of piezoelectricity is successfully achieved from centrosymmetric SrFeO3‐x by modulating oxygen vacancies, which have a surface piezoelectric potential up to 93 mV by using...
The rapid increase and spread of Gram‐negative bacteria resistant to many or all existing treatments threaten a return to the preantibiotic era. The presence of bacterial polysaccharides that impede the penetration of many antimicrobials and protect them from the innate immune system contributes to resistance and pathogenicity. No currently approved antibiotics target the polysaccharide regions of...
Despite the promising achievements of immune checkpoint blockade (ICB) therapy for tumor treatment, its therapeutic effect against solid tumors is limited due to the suppressed tumor immune microenvironment (TIME). Herein, a series of polyethyleneimine (Mw = 0.8k, PEI0.8k)‐covered MoS2 nanosheets with different sizes and charge densities are synthesized, and the CpG, a toll‐like receptor‐9 agonist,...
The oxygen evolution reaction (OER) has significant effects on the water‐splitting process and rechargeable metal‐air batteries; however, the sluggish reaction kinetics caused by the four‐electron transfer process for transition metal catalysts hinder large‐scale commercialization in highly efficient electrochemical energy conversion devices. Herein, a magnetic heating‐assisted enhancement design...
The design of nanomedicine for cancer therapy, especially the treatment of tumor metastasis has received great attention. Proteasome inhibition is accepted as a new strategy for cancer therapy. Despite being a big breakthrough in multiple myeloma therapy, carfilzomib (CFZ), a second‐in‐class proteasome inhibitor is still unsatisfactory for solid tumor and metastasis therapy. In this study, hollow...
Designing cost‐effective, highly active, and durable platinum (Pt)‐based electrocatalysts is a crucial endeavor in electrochemical hydrogen evolution reaction (HER). Herein, the low‐content Pt (0.8 wt%)/tungsten oxide/reduced graphene oxide aerogel (LPWGA) electrocatalyst with excellent HER activity and durability is developed by employing a tungsten oxide/reduced graphene oxide aerogel (WGA) obtained...
The fabrication of silicon (Si) anode materials derived from high silica‐containing plants enables effective utilization of subsidiary agricultural products. However, the electrochemical performances of synthesized Si materials still require improvement and thus need further structural design and morphology modifications, which inevitably increase preparation time and economic cost. Here, the conversion...
In article 1901466, Bo Chi, Gregory J. Wilson, and co‐workers investigate superior electronic properties of nanostructured tin (IV) oxide (SnO2) as an ideal inorganic electron transport layer (ETL) in n–i–p perovskite solar cells. The bilayer ETL architecture attaining impressive power conversion efficiency (PCE) greater than 20% is depicted.
Nanostructured tin (IV) oxide (SnO2) is emerging as an ideal inorganic electron transport layer in n–i–p perovskite devices, due to superior electronic and low‐temperature processing properties. However, significant differences in current–voltage performance and hysteresis phenomena arise as a result of the chosen fabrication technique. This indicates enormous scope to optimize the electron transport...
Inspired by bio‐enzymes, multistep cascade reactions are highly attractive in catalysis. Despite extensive research in recent years, it remains a challenge to promote the stability and activity of catalysts. Here, well‐defined core–shell structured Ag–Au nanocage@CeO2 (Ag–Au NC@CeO2) are designed by a simple and facile self‐assembly method. The results indicate that the Ag–Au NC@CeO2 has glucose oxidase‐like...
Herein, a unique ganoderma‐like MoS2/NiS2 hetero‐nanostructure with isolated Pt atoms anchored is reported. This novel ganoderma‐like heterostructure can not only efficiently disperse and confine the few‐layer MoS2 nanosheets to fully expose the edge sites of MoS2, and provide more opportunity to capture the Pt atoms, but also tune the electronic structure to modify the catalytic activity. Because...
In article number 1800697, Yu Wang and co‐workers report a unique ganoderma‐like MoS2/NiS2 hetero‐nanostructure with isolated Pt atoms anchored. The ganoderma‐like heterostructure can not only change the electronic state, but also evenly disperse and anchor the few‐layer MoS2. Single Pt atoms, just as spores anchored on ganoderma, can greatly activate the in‐plane S atoms. The synergy of the ganoderma‐like...
Metal–organic frameworks (MOFs) with tunable compositions and morphologies are recognized as efficient self‐sacrificial templates to achieve function‐oriented nanostructured materials. Moreover, it is urgently needed to develop highly efficient noble metal‐free oxygen evolution reaction (OER) electrocatalysts to accelerate the development of overall water splitting green energy conversion systems...
Metal–organic frameworks (MOFs) featuring versatile topological architectures are considered to be efficient self‐sacrificial templates to achieve mesoporous nanostructured materials. A facile and cost‐efficient strategy is developed to scalably fabricate binary metal oxides with complex hollow interior structures and tunable compositions. Bimetal–organic frameworks of Ni‐Co‐BTC solid microspheres...
