2D MXene‐Ti3C2Tx holds great promise in various electronic applications, especially for electromagnetic interference (EMI) shielding devices and supercapacitors. Ti3C2Tx synthesis typically involves the use of hazardous fluorine‐containing chemicals that can result in the formation of inert fluoride functional groups on the surface of Ti3C2Tx, severely degrading its properties and posing a threat...
Metal oxides with diverse compositions and structures have garnered considerable interest from researchers in various reactions, which benefits from transmission electron microscopy (TEM) in determining their morphologies, phase, structural and chemical information. Recent breakthroughs have made liquid‐phase TEM a promising imaging platform for tracking the dynamic structure, morphology, and composition...
Recent developments in antimicrobial peptides (AMPs) have focused on the rational design of short sequences with less than 20 amino acids due to their relatively low synthesis costs and ease of correlation of the structure‐function relationship. However, gaps remain in the understanding of how short cationic AMPs interact with the bacterial outer and inner membranes to affect their antimicrobial efficacy...
Active and durable bifunctional electrocatalysts for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) on the cathode are required for high‐performance rechargeable metal‐air batteries. Herein, the synthesis of hierarchically porous nitrogen‐doped carbon (HPNC) with bifunctional oxygen electrocatalysis for Zn‐air batteries is reported. The HPNC catalyst possesses a large surface...
Invoking the occurrence of pyroptosis is an emerging strategy for the treatment of cancer. However, the practical applications of pyroptosis for cancer therapy are currently hindered due to the lack of tumor‐specific and efficient pyroptotic agents in vivo. Herein, a virus‐spike tumor‐activatable pyroptotic agent (VTPA) for cancer‐specific therapy is reported. The VTPA is composed of an organosilica...
The electrochemical CO2 reduction reaction (CO2RR) to syngas represents a promising solution to mitigate CO2 emissions and manufacture value‐added chemicals. Palladium (Pd) has been identified as a potential candidate for syngas production via CO2RR due to its transformation to Pd hydride under CO2RR conditions, however, the pre‐hydridized effect on the catalytic properties of Pd‐based electrocatalysts...
Triple‐negative breast cancer (TNBC) is highly aggressive and insensitive to conventional targeted therapies, resulting in poor therapeutic outcomes. Recent studies have shown that abnormal iron metabolism is observed in TNBC, suggesting an opportunity for TNBC treatment via the iron‐dependent Fenton reaction. Nevertheless, the efficiency of current Fenton reagents is largely restricted by the lack...
In article number 2002537, Fangyuan Li, Qiang Ding, Daishun Ling, and co‐workers report core–shell–satellite nanomaces composed of mesoporous silica coated gold nanorod and surface grafted ultrasmall iron oxide nanoparticles. By exploiting the vulnerability of iron efflux in triple‐negative breast cancer (TNBC) cells, the nanomaces exhibit a photothermal enhanced Fenton reaction‐mediated anti‐cancer...
In article number 1901397, Yu Shrike Zhang, Ai‐Zheng Chen, and co‐workers fabricate highly open porous microspheres (HOPMs) using a microfluidic technique for harboring skeletal myoblasts towards cell delivery applications in situ. The structure of the HOPMs conveniently provides a favorable microenvironment for cell adhesion and proliferation, improved cell retention and vascularization, as well...
Microscale cell carriers have recently garnered enormous interest in repairing tissue defects by avoiding substantial open surgeries using implants for tissue regeneration. In this study, the highly open porous microspheres (HOPMs) are fabricated using a microfluidic technique for harboring proliferating skeletal myoblasts and evaluating their feasibility toward cell delivery application in situ....
Herein, the assembly of 3D uniform gear‐like architectures is demonstrated with a tobacco mosaic virus (TMV) disk as a building block. In this context, the intrinsic behavior of the TMV disk that promotes its assembly into nanotubes is altered by a synergistic effect of dual functional modifications at the 53rd arginine mutation and the introduction of lysine groups in the periphery at 1st and 158th...
