High‐capacity Li‐rich layered oxides (LLOs) suffer from severe structure degradation due to the utilization of hybrid anion‐ and cation‐redox activity. The native post‐cycled structure, composed of progressively densified defective spinel layer (DSL) and intrinsic cations mixing, is deemed as the hindrance of the rapid and reversible de/intercalation of Li+. Herein, the artificial post‐cycled structure...
The construction of a protective layer for stabilizing anion redox reaction is the key to obtaining long cycling stability for Li‐rich Mn‐based cathode materials. However, the protection of the exposed surface/interface of the primary particles inside the secondary particles is usually ignored and difficult, let alone the investigation of the impact of the surface engineering of the internal primary...
Metal–sulfur batteries exhibit great potential as next‐generation rechargeable batteries due to the low sulfur cost and high theoretical energy density. Sodium–sulfur (Na–S) batteries present higher feasibility of long‐term development than lithium–sulfur (Li–S) batteries in technoeconomic and geopolitical terms. Both lithium and sodium are alkali metal elements with body‐centered cubic structures,...
The high capacity of Li‐rich and Mn‐based (LRM) cathode materials is originally due to the unique hybrid anion‐ and cation redox, which also induces detrimental oxygen escape. Furthermore, the counter diffusion of released oxygen (into electrolyte) and induced oxygen vacancies (into the interior bulk phase) that occurs at the interface will cause uncontrolled phase collapse and other issues. Therefore,...
Oral cancer has a high mortality rate, and its treatment often causes debilitating complications. More than 90% of oral cancers are oral squamous cell carcinomas (OSCCs) that may develop from clinically recognizable oral premalignant lesions (OPLs). To eradicate OPLs before they turn into cancers, a non‐invasive topical formulation is developed based on a novel combination of synergistically acting...
Quasi‐2D perovskites are enchanting alternative materials for solar cells due to their intrinsic stability. The manipulation of crystal orientation of quasi‐2D perovskites is indispensable to target efficient devices, however, the origin of orientation during the film fabrication process still lacks in‐depth understanding and convincing evidence yet, which hinders further boosting the performance...
Designing and constructing bimetallic hierarchical structures is vital for the conversion‐alloy reaction anode of sodium‐ion batteries (SIBs). Particularly, the rationally designed hetero‐interface engineering can offer fast diffusion kinetics in the interface, leading to the improved high‐power surface pseudocapacitance and cycling stability for SIBs. Herein, the hierarchical zinc–tin sulfide nanocages...
Ag2S quantum dots (QDs) are well‐known near‐infrared fluorophores and have attracted great interest in biomedical labeling and imaging in the past years. However, their photoluminescence efficiency is hard to compete with Cd‐, Pb‐based QDs. The high Ag+ mobility in Ag2S crystal, which causes plenty of cation deficiency and crystal defects, may be responsible mainly for the low photoluminescence quantum...
3D Graphene sheets encapsulated amorphous hollow CoSnO3 nanoboxes (H‐CoSnO3@reduced graphene oxide [RGO]) are successfully fabricated by first preparing 3D graphene oxides encapsulated solid CoSn(OH)6 nanocubes, followed by an alkaline etching process and subsequent heating treatment in Ar. The hollow CoSnO3 nanoboxes with average particle size of 230 nm are uniformly and tightly encapsulated by RGO...
