Developing porous adsorbents for efficient separation of C4 olefins is significant but challenging in the petrochemical industry due to their similar molecular sizes and physical properties. The separation efficiency is often limited when separating C4 olefins by a single separation mechanism. Herein, an ultramicroporous yttrium‐based MOF, Y‐dbai, is reported featuring cage‐like pores connected by...
Bimetallic nanomaterials (BNMs) have been used in sensing, biomedicine, and environmental remediation, but their multipurpose and comprehensive applications in molecular logic computing and information security protection have received little attention. Herein, This synthesis method is achieved by sequentially adding reactants under ice bath conditions. Interestingly, Ag‐Cr NPs can dynamically selectively...
Oncolytic Virotherapies
In article number 2206948, Ying Wu, Ning Li, Funan Liu, and co‐workers provide a more advanced approach to cancer immunotherapy, i.e. the oncolytic virotherapy. Oncolytic viruses selectively replicate in tumor cells and exert antitumor effects through direct oncolysis and inducting immune responses, where tumor antigens from the lysing cells enhance antitumor immunity.
With advances in cancer biology and an ever‐deepening understanding of molecular virology, oncolytic virus (OV)‐driven therapies have developed rapidly and become a promising alternative to traditional cancer therapies. In recent years, satisfactory results for oncolytic virus therapy (OVT) are achieved at both the cellular and organismal levels, and efforts are being increasingly directed toward...
Pd‐NO2‐UiO‐66 for DMC Catalysis
In article number 2208238, Ye‐Yan Qin, Yuan‐Gen Yao, and co‐workers first introduce acidity/alkalinity functionalized metal–organic frameworks (MOFs) into dimethyl carbonate (DMC) catalysis, and the Lewis acidic Pd‐NO2‐UiO‐66 exhibits excellent catalytic behavior. In addition to affecting the interaction of Pd(II) and support, the ‐NO2 group has a dominant role in the...
The acid–base properties of supports have an enormous impact on catalytic reactions to regulate the selectivity and activity of supported catalysts. Herein, a train of Pd‐X‐UiO‐66 (X = NO2, NH2, and CH3) catalysts with different acidity/alkalinity functional groups and encapsulated Pd(II) species is first developed, whose activities in dimethyl carbonate (DMC) catalysis are then investigated in...
The development of probes for early monitoring tumor therapy response may greatly benefit the promotion of photodynamic therapy (PDT) efficacy. Singlet oxygen (1O2) generation is a typical indicator for evaluating PDT efficacy in cancer. However, most existing probes cannot quantitatively detect 1O2 in vivo due to the high reactivity and transient state, and thus have a poor correlation with PDT response...
Using magnetomechanical force to kill cancer cells has attracted great attention recently. This study presents novel hedgehog‐like microspheres composed of needle‐like magnetic nanoparticles with carbon and gold double shells. Using a novel low‐frequency vibrating magnetic field (VMF), these microspheres with sharp surfaces can seriously damage cancer cells and strongly inhibit mouse tumor growth...
The red P anode for sodium ion batteries has attracted great attention recently due to the high theoretical capacity, but the poor intrinsic electronic conductivity and large volume expansion restrain its widespread applications. Herein, the red P is successfully encapsulated into the cube shaped sandwich‐like interconnected porous carbon building (denoted as P@C‐GO/MOF‐5) via the vaporization–condensation...
To develop high‐performance sodium‐ion batteries (NIBs), electrodes should possess well‐defined pathways for efficient electronic/ionic transport. In this work, high‐performance NIBs are demonstrated by designing a 3D interconnected porous structure that consists of N, S co‐doped 3D porous graphene frameworks (3DPGFs‐NS). The most typical electrode materials (i.e., Na3V2(PO4)3 (NVP), MoS2, and TiO...
Black phosphorus (BP) nanomaterials have emerged as rapidly rising stars in the field of nanomedicine. In this work, BP quantum dots (BPQDs) are synthesized and their potential as photosensitizers is investigated for the first time. The BPQDs present good stability in physiological medium and no appreciable cytotoxicity. More importantly, the BPQDs can be rapidly eliminated from the body in their...
TiO2 as an anode for sodium‐ion batteries (NIBs) has attracted much recent attention, but poor cyclability and rate performance remain problematic owing to the intrinsic electronic conductivity and the sluggish diffusivity of Na ions in the TiO2 matrix. Herein, a simple process is demonstrated to improve the sodium storage performance of TiO2 by fabricating a 1D, multichannel, porous binary‐phase...
Nitrogen‐doped ordered mesoporous TiO2 nanofibers (N‐MTO) have been fabricated by electrospinning and subsequent nitridation treatment. The N‐doping in TiO2 leads to the formation of Ti3+, resulting in the improved electron conductivity of TiO2. In addition, one‐dimensional (1D) N‐MTO nanostructure possesses very short diffusion length of Na+/e− in N‐MTO, easy access of electrolyte, and high conductivity...
On page 3522, Y. Yu and co‐workers fabricate nitrogen‐doped ordered mesoporous TiO2 nanofibers (denoted as N‐MTO) by electrospinning and subsequent nitridation treatment. Nitrogen atoms are successfully doped into the TiO2 lattice, accompanied by the formation of Ti3+ and oxygen vacancies, contributing to the improvement of electronic conductivity of TiO2. When used as an anode for a sodium‐ion battery,...
