Herein, the vitamin K2 (VK2)/maleimide (MA) coloaded mesoporous silica nanoparticles (MSNs), functional molecules including folic acid (FA)/triphenylphosphine (TPP)/tetrapotassium hexacyanoferrate trihydrate (THT), as well as CaCO3 are explored to fabricate a core‐shell‐corona nanoparticle (VMMFTTC) for on‐demand anti‐tumor immunotherapy. After application, the tumor‐specific acidic environment first...
High nickel cathode material LiNixCoyMn1−x−yO2 (NCM) (x ≥ 0.6) has represented the most critical material in virtue of outstanding specific capacity and low self‐discharge. However, the high surface alkalinity and detrimental interfacial stability lead to the parasitic reaction and a series of phase deterioration. Herein, in situ cross‐linking binder molecular chains with a 3D network structure to...
Cancer immunotherapy has attracted considerable attention due to its advantages of persistence, targeting, and ability to kill tumor cells. However, the efficacy of tumor immunotherapy in practical applications is limited by tumor heterogeneity and complex tumor immunosuppressive microenvironments in which abundant of M2 macrophages and immune checkpoints (ICs) are present. Herein, two type‐I aggregation‐induced...
Cross‐scale micro‐nano structures play an important role in semiconductors, MEMS, chemistry, and cell biology. Positive photoresist is widely used in lithography due to the advantages of high resolution and environmental friendliness. However, cross‐scale micro‐nano structures of positive photoresist are difficult to flexibly pattern, and the feature resolution is limited by the optical diffraction...
Responsive structural colors from artificially engineered micro/nanostructures are critical to the development of anti‐counterfeiting, optical encryption, and intelligent display. Herein, the responsive structural color of hydrogel micropillar array is demonstrated under the external stimulus of ethanol vapor. Micropillar arrays with full color are fabricated via femtosecond laser direct writing by...
The rational design of novel high‐performance cathode materials for sodium‐ion batteries is a challenge for the development of the renewable energy sector. Here, a new sodium‐deficient NASICON phosphate, namely Na3.40□0.60Co0.5Fe0.5V(PO4)3, demonstrating the excellent electrochemical performance is reported. The presence of Co allows a third Na+ to participate in the reaction thus exhibiting a high...
Continuous Covalent Organic Frameworks Membranes
Advanced covalent organic frameworks (COFs) membranes have received a lot of attention and a better trade‐off between selectivity and permeability can be achieved due to the tunable pore size, high porosity, unique pore structure and the abundance of molecular/ion‐specific functional groups on the framework. In article number 2303757, Li Gao, Xiaoming...
Covalent organic frameworks (COFs) are porous crystalline polymeric materials formed by the covalent bonding of organic units. The abundant organic units library gives the COFs species diversity, easily tuned pore channels, and pore sizes. In addition, the periodic arrangement of organic units endows COFs regular and highly connected pore channels, which has led to the rapid development of COFs in...
With the development of bionics as well as materials science, intelligent soft actuators have shown promising applications in many fields such as soft robotics, sensing, and remote manipulation. Microfabrication technologies have enabled the reduction of the size of responsive soft actuators to the micron level. However, it is still challenging to construct microscale actuators capable of responding...
Atmospheric water harvesting is considered a viable source of freshwater to alleviate water scarcity in an arid climate. Water condensation tends to be more efficient on superhydrophobic surfaces as the spontaneous coalescence‐induced droplet jumping on superhydrophobic surfaces enables faster condensate removal. However, poor water nucleation on these surfaces leads to meager water harvest. A conventional...
Branched Siloxane Brushes
In article number 2301561, King Lun Yeung and co‐workers develop a flexible and hierarchically branched siloxane brushes by repeated grafting of siloxane on TiO2 nanorods. The flexible siloxane facilitates water nucleation, while the branched structure promotes efficient droplet jumping. The as‐prepared surface displays a significant improvement in water harvesting at both...
Zn2+‐induced β‐amyloid protein (Aβ) aggregation and microglia activation are the predominant contributors in Alzheimer's disease (AD). Regulating intracephalic excessive Zn2+ is a promising therapeutic strategy for AD treatment. However, only inhibition of Zn2+ is hardly to repair continuous damages caused by activated microglia. Herein, an intelligent resveratrol‐loaded supramolecular vesicles (RES‐loaded...
Pressure‐stabilized high‐entropy sulfide (FeCoNiCuRu)S2 (HES) is proposed as an anode material for fast and long‐term stable lithium/sodium storage performance (over 85% retention after 15 000 cycles @10 A g−1). Its superior electrochemical performance is strongly related to the increased electrical conductivity and slow diffusion characteristics of entropy‐stabilized HES. The reversible conversion...
Cell aggregates as a 3D culture model can effectively mimic the physiological processes such as embryonic development, immune response, and tissue renewal in vivo. Researches show that the topography of biomaterials plays an important role in regulating cell proliferation, adhesion, and differentiation. It is of great significance to understand how cell aggregates respond to surface topography. Herein,...
Macrophages as the main cause of cancer immunosuppression, how to effectively induce macrophage M1 polarization remain the major challenge in lung cancer therapy. Herein, inspired by endogenous reactions, a strategy is proposed to coactivate macrophage M1 polarization by reactive oxygen species (ROS) and nitric oxide (NO) with self‐autocatalytic cascade reaction. To enhance the generation of NO and...
Because of their exceptional physical and thermal properties, cellulose nanocrystals (CNCs) are a highly promising bio‐based material for reinforcing fillers. Studies have revealed that some functional groups from CNCs can be used as a capping ligand to coordinate with metal nanoparticles or semiconductor quantum dots during the fabrication of novel complex materials. Therefore, through CNCs ligand...
