Herein, a type of hypervalent iodine compound—iodosobenzene (PhIO)—is proposed to regulate the LiPSs electrochemistry and enhance the performance of Li‐S battery. PhIO owns the practical advantages of low‐cost, commercial availability, environmental friendliness and chemical stability. The lone pair electrons of oxygen atoms in PhIO play a critical role in forming a strong Lewis acid–base interaction...
Metal single atom catalysts (SAC) have been successfully used in heterogeneous catalysis but developing a scalable and economic support for SAC is still a great challenge. Here, cyclized polyacrylonitrile (CPAN) is proposed as a promising support for single atom metal catalysts. CPAN can be easily prepared from cheap industrial product polyacrylonitrile (PAN), which has excellent processability. A...
Metal peroxide nanoparticles designed to elevate the oxidative stress are considered a promising nanotherapeutics in biomedical applications, including chemotherapy, photodynamic therapy, and bacterial disinfection. However, their lack of specificity towards the therapeutic target can cause toxic side effects to healthy tissues. Here, silver peroxide nanoparticles (Ag2O2 NPs) capable of controlled...
Photothermal Therapy
In article number 2104585, Fubing Wang, Xiangheng Xiao, and co‐workers use cancer cell homologous exosome vesicles as a carrier, and with the help of its homing effect, the photothermal nanomedicine can be accurately delivered to the tumor area for aggregation. Nanomedicine then enters into the cell through its strong penetration effect. The precise positioning of external laser...
Nanocancer medicine, such as photothermal therapy (PTT), as a promising way to solve cancer without side effects, faces a huge biological barrier during the circulation of nanoparticles in the body, including nanobiological interactions in the blood, isolation of nanoparticles in the macrophage system, tumor spillover effect, and especially uneven intratumoral distribution of nanoparticles, which...
Mesocarbon microbeads (MCMB) are highly desirable as anode materials for rechargeable potassium ion batteries (PIBs) due to their commercially availability, high stability and low‐cost. However, their charge storage and interfacial mechanisms are still unclear. In this work, the intercalation mechanisms and the solid‐electrolyte‐interphase (SEI) formation of the MCMB in four different electrolytes...
Solar‐driven vaporization is a sustainable solution to water and energy scarcity. However, most of the present evaporators are still suffering from inefficient utilization of converted thermal energy. Herein, a universal sandwich membrane strategy is demonstrated by confining the hierarchical porous carbon cells in two energy barriers to obtain a high‐efficiency evaporator with a rapid water evaporation...
Extrinsic probes have outstanding properties for intracellular labeling to visualize dynamic processes in and of living cells, both in vitro and in vivo. Since extrinsic probes are in many cases cell‐impermeable, different biochemical, and physical approaches have been used to break the cell membrane barrier for direct delivery into the cytoplasm. In this Review, these intracellular delivery strategies...
In article number 2000779, Shikuan Yang, Xiangheng Xiao, and co‐workers develop springtail‐inspired superamphiphobic ordered nanohoodoo arrays with quasi‐doubly reentrant structures. The arrays have outstanding performance and wide applications. The simple and massive production of the superamphiphobic nanohoodoo structures will push their practical application processes in diverse fields where wettability...
The skin of springtails is well‐known for being able to repel water and organic liquids using their hexagonally arranged protrusions with reentrant structures. Here, a method to prepare 100 nm‐sized nanohoodoo arrays with quasi‐doubly reentrant structures over square centimeters through combining the nanosphere lithography and the template‐protected selective reactive ion etching technique is demonstrated...
At present, developing therapeutic strategies to improve wound healing in individuals with diabetes remains challenging. Exosomes represent a promising nanomaterial from which microRNAs (miRNAs) can be isolated. These miRNAs have the potential to exert therapeutic effects, and thus, determining the potential therapeutic contributions of specific miRNAs circulating in exosomes is of great importance...
A new conceptual injectable and radiopaque liquid metal/calcium alginate (LM/CA) hydrogel is proposed and demonstrated in article number 1903421 by Jing Liu and co‐workers for endovascular embolization and tumor embolotherapy. It is shown that such a hydrogel displays high flexibility and radiopacity due to the introduction of LM droplets. It also owns excellent biocompatibility and hemocompatibility...
Improved endovascular embolization can contribute to assistant treatment for patients. However, many traditional embolic materials, such as metal microcoils or liquid embolic agents, are associated with limitations of coil migration or recanalization. Herein, as the first trial, an injectable and radiopaque liquid metal/calcium alginate (LM/CA) hydrogel is introduced and fabricated as a candidate...
Studies on distinctive performances and novel applications of amorphous inorganic nanomaterials are becoming attractive. Herein, Ag2S amorphous and crystalline nanodots (ANDs and CNDs) are prepared via facile methods. In vitro and in vivo studies indicate that Ag2S ANDs, rather than CNDs, can induce the self‐destruction of tumors, which can be attributed to their distinctive chemical properties, e...
Nanomaterials have gained plenty of research interest because of their excellent performance, which is derived from their small size and special structure. In practical applications, to acquire nanomaterials with high performance, many methods have been used to modulate the structure and components of materials. To date, ion beam techniques have extensively been applied for modulating the performance...
The significant issues with alkali metal batteries arise from their poor electrochemical properties and safety problems, limiting their applications. Herein, TiO2 nanoparticles embedded into N‐doped porous carbon truncated ocatahedra (TiO2⊂NPCTO) are engineered as a cathode material with different metal anodes, including solid Na or K and liquid Na–K alloy. Electrochemical performance and kinetics...
Cucurbit[8]uril (CB[8]) is unique and notable in the cucurbit[n]uril family, since it has a relatively large cavity and thus is able to simultaneously accommodate two guest molecules. Typically, an electron‐deficient first guest and an electron‐rich second guest can be bound by CB[8] to form a stable 1:1:1 heteroternary supramolecular complex. Additionally, two homo guests can also be strongly dimerized...
Even though transition metal dichalcogenides (TMDCs) are deemed to be novel photonic and optoelectronic 2D materials, the visible band gap being often limited to monolayer, hampers their potential in niche applications due to fabrication challenges. Uncontrollable defects and degraded functionalities at elevated temperature and under extreme environments further restrict their prospects. To address...
In article number 1603830, by Sijin Liu and co‐workers, the exposure of multi‐wall carbon nanotubes (MWCNTs) alters hepatic hepcidin‐mediated systemic iron homeostasis through pro‐inflammatory responses in mice, leading to limited iron availability for red blood cell formation, and eventually the development of anemia of inflammation. This study opens a new path to understanding the biological impacts...
Although numerous toxicological studies have been performed on carbon nanotubes (CNTs), a few studies have investigated their secondary and indirect effects beyond the primary target tissues/organs. Here, a cascade of events are investigated: the initiating event and the subsequent key events necessary for the development of phenotypes, namely CNT‐induced pro‐inflammatory effects on iron homeostasis...
