Graphene‐based materials (GBMs) possess a unique set of properties including tunable interlayer channels, high specific surface area, and good electrical conductivity characteristics, making it a promising material of choice for making electrode in rechargeable batteries. Lithium‐ion batteries (LIBs) currently dominate the commercial rechargeable battery market, but their further development has been...
Triggering reversible lattice oxygen redox (LOR) in oxide cathodes is a paradigmatic approach to overcome the capacity ceiling determined by orthodox transition‐metal (TM) redox. However, the LOR reactions in P2‐structured Na‐layered oxides are commonly accompanied by irreversible nonlattice oxygen redox (non‐LOR) and large local structural rearrangements, bringing about capacity/voltage fading and...
Precise structural control has attracted tremendous interest in pursuit of the tailoring of physical properties. Here, this work shows that through strong ligand‐mediated interfacial energy control, Au‐Cu2O dumbbell structures where both the Au nanorod (AuNR) and the partially encapsulating Cu2O domains are highly crystalline. The synthetic advance allows physical separation of the Au and Cu2O domains,...
The development of heteroaromatic conjugated porous polymers (H‐CPPs) have received enormous research interests, because of the important functional roles of the heteroatoms in photocatalysis and proton conduction. However, due to the synthetic challenges deriving from the stable structures, the structural diversity and synthetic methods of them are still limited. Herein, a new type of H‐CPPs, covalent...
Pancreatic ductal adenocarcinoma (PDAC) is on of the most lethal malignant tumors with relatively poor prognosis, characterized with insufficient drug penetration, low immune response and obvious drug resistances. The therapeutic inefficiency is multifactorially related to its specific tumor microenvironment (TME), which is representatively featured as rich stroma and immunosuppression. In this work,...

In article number 2107712, Tao Sun, Chen Jiang, and co‐workers develop a versatile drug delivery system that can co‐encapsulate two hypoxia‐responsive prodrugs modified from gemcitabine and a STAT3 inhibitor. The system can respond to the gradient pH variation in the tumor microenvironment to realize higher penetration by reversing its surficial charges, with the aim of...
Developing highly efficient bifunctional catalysts for the oxygen reduction and oxygen evolution reaction (ORR/OER) can open possibilities for future zinc air batteries (ZABs). Herein, cost‐effective and highly conductive few‐layer ferric and nickel chloride co‐intercalated graphite intercalation compounds (FeCl3‐NiCl2‐GIC) are designed as bifunctional oxygen catalysts for ZAB. The optimized few‐layer...
Hepatocellular carcinoma (HCC) is one of the most fatal malignancies with few effective treatment options all around the world. The efficacy of the arisen immune checkpoint therapy is still uncertain due to local immunosuppression. In order to further overcome T cell suppression in the tumor immune microenvironment while promoting the immune response of antigen‐presenting cells, a biointerfacing antagonizing...

In article number 2105237, Dong‐Sheng Huang, Tian Yang, and co‐workers develop a strategy of targeting therapeutic nanoparticles effectively reversing the immune‐inhibiting microenvironment for enhanced PD‐L1 checkpoint combination therapy. The platelet membrane cloaked nanoparticles activate the CD8+ T lymphocytes and antigen presentation of dendritic cells as well as...
CsPbX3 perovskite nanocrystals (NCs), with excellent optical properties, have drawn considerable attention in recent years. However, they also suffer from inherent vulnerability and hydrolysis, causing the new understanding or new applications to be difficultly explored. Herein, for the first time, it is discovered that the phospholipid membrane (PM)‐coated CsPbX3 NCs have intrinsic biocatalytic activity...
The instability of interfacial solid‐electrolyte interphase (SEI) layer of metallic sodium (Na) anode during cycles results in the rapid capacity decay of sodium metal batteries (SMBs). Herein, the concept of interfacial protection engineering of Na nanoparticles (Na‐NPs) is proposed first to achieve stable, dendrite‐free, and long‐life SMB. Employing an ion‐exchange strategy, conformal Sn‐Na alloy‐SEI...
Two identical layered metal–organic frameworks (MOFs) (CoFRS and NiFRS) are constructed by using flexible 1,10‐bis(1,2,4‐triazol‐1‐yl)decane as pillars and 1,4‐benzenedicarboxylic acid as rigid linkers.

The oxygen evolution reaction (OER) catalytic activity of a transition metal oxides/hydroxides based electrocatalyst is related to its pseudocapacitance at potentials lower than the OER standard potential. Thus, a well‐defined pseudocapacitance could be a great supplement to boost OER. Herein, a highly pseudocapacitive Ni‐Fe‐Co hydroxides/N‐doped carbon nanoplates (NiCoFe‐NC)‐based electrocatalyst...
