Multidrug Delivery Microrobots
Dong Sun and co‐workers fabricate the multidrug delivery microrobot by a step‐by‐step 3D printing method using different biodegradable materials. It includes three components: skeleton, head, and body. The skeleton can respond to magnetic fields for microrobot actuation and drug‐targeted delivery. The drugs are separately stored in the head and body to enhance the synergistic...
Biomimetic Nanoparticles
In article number 2301439, Rutong Yu, Xiuping Zhou, and co‐workers construct a Trojan‐horse‐like nanoparticle system (R‐NKm@NPs), which traverses across the blood‐brain barrier (BBB) and targets glioblastoma through the natural killer (NK) cell membrane decorated with cRGD. Notably, the R‐NKm@NPs exhibit good antitumor ability by locally releasing temozolomide (TMZ) and IL‐15,...
Digital‐Resolution Ultrasensitive Protein Detection
The synergistic coupling between a plasmonic nanostructure and a photonic crystal resonator enables a 52‐fold improvement in the emission intensity of fluorescent dye molecules due to strong near‐field enhancement, improved extraction efficiency, and an increased rate of spontaneous emission. This substantial boost in signal‐to‐noise ratio allows...
Reversed Mitochondrial Dysfunction
Fullerenol nanoparticles are both stable and effective in protecting the degenerating retina. In article number 2205998, Yu Gong, Zhanjun Gu, Haiwei Xu, and co‐workers propose the potential utility of fullerenols for safeguarding the mitochondrial genome to maintain electron transport chain function and simultaneously reversing the abnormal nuclear DNA expression...
Owing to outstanding optoelectronic properties, lead halide perovskite nanocrystals (PNCs) are considered promising emitters for next‐generation displays. However, the development of pure blue (460‐470 nm) perovskite nanocrystal light‐emitting diodes (PNC‐LEDs), which correspond to the requirements of Rec. 2020 standard, lag far behind that of their green and red counterparts. Here, pure blue CsPb(Br/Cl)...
Intervertebral Disc Degeneration
A biomimetic peptide (OAFF) binds to C‐X‐C motif chemokine receptor 1 (CXCR1) and forms fibrous networks on nucleus pulposus stem cells (NPSCs) for mimicking extracellular matrix formation, which induces NPSCs quiescence and ultimately overcomes obstacle in intradiscal injection therapy. More details can be found in article number 2300578 by Lei Wang, Bo Huang, and...
Highly Efficient Cold Protection
A tri‐layered bicomponent microfilament composite fabric comprised of a hydrophobic layer of PET/PA@C6F13 bicomponent microfilament webs, an adhesive layer of LPET/PET fibrous web, and a fluffy‐soft layer of PET/Cellulous fibrous web have been designed and also successfully been fabricated, promoting multiple advantages of waterproof breathable properties and high...
Adaptive Ultramicroporous Frameworks
In article number 2302677, Qihui Chen, Maochun Hong, and co‐workers develop an acid‐base resistant ultramicroporous framework. It can sieve CO2 from humid air with the very high adsorption capacity/selectivity but the very low adsorption enthalpy. Here, the adsorbed‐CO2‐driven pore shrinkage can promote CO2 capture while the adsorbed‐H2O‐induced phase transitions...
The metal–insulator transition (MIT) of vanadium dioxide (VO2) has been of great interest in materials science for both fundamental understanding of strongly correlated physics and a wide range of applications in optics, thermotics, spintronics, and electronics. Due to the merits of chemical interaction with accessibility, versatility, and tunability, chemical modification provides a new perspective...
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...
ZnO Nanostructures
In article number 2302864, Breanna Clarke and Khashayar Ghandi provide a background on the structure, an analysis of the growth kinetics and mechanisms in‐solution, and on substrates, and properties of ZnO nanostructures. ZnO nanostructures have applications in sensing, photocatalysis, functional textiles, and cosmetic industries, which are described in this article. The contradictions...
Silicon Anodes
In article number 2302486, Martin Winter, Masoud Baghernejad, and co‐workers investigate the complementary effect of fluoroethylene carbonate (FEC) and ethoxy(pentafluoro) cyclotriphosphazene as additive compounds in an aprotic organic electrolyte in NCM523 II SiOx/C pouch cells. The authors discuss a novel property of FEC, here called molecular‐cling‐effect (MCE) and verified it with...
The fabrication of low‐cost, effective, and highly integrated nanostructured materials through simple and reproducible methods for high‐energy‐density supercapacitors is highly desirable. Herein, an activated carbon cloth (ACC) is designed as the functional scaffold for supercapacitors and treated hydrothermally to deposit NiCo nanoneedles working as internal core, followed by a dip‐dry coating of...
Herein, the electrochemical properties and reaction mechanism of Li3‒2xCaxV2(PO4)3/C (x = 0, 0.5, 1, and 1.5) as negative electrode materials for sodium‐ion/potassium‐ion batteries (SIBs/PIBs) are investigated. All samples undergo a mixed contribution of diffusion‐controlled and pseudocapacitive‐type processes in SIBs and PIBs via Trasatti Differentiation Method, while the latter increases with Ca...
Aqueous zinc‐ion batteries have received continuous interests because of applying low‐cost and eco‐friendly aqueous electrolytes and having high safety. Beyond energetically to explore new‐type cathode materials, it is of great significance to regulate the zinc storage behavior of the existing cathodes in order to understand the underlying working mechanism. Therefore, as a proof of concept, this...
Herein, a patterned rod‐like CoP@NiCoP core‐shell heterostructure is designed to consist of CoP nanowires cross‐linked with NiCoP nanosheets in tight strings. The interfacial interaction within the heterojunction between the two components generates a built‐in electric field that adjusts the interfacial charge state and create more active sites, accelerating the charge transfer and improving supercapacitor...
1D van der Waals (vdW) materials have attracted significant interest in recent years due to their giant anisotropic and weak interlayer‐coupled characters. More 1D vdW materials are urgently to be exploited for satisfying the practice requirement. Herein, the study of 1D vdW ternary HfSnS3 high‐quality single crystals grown via the chemical vapor transport technique is reported. The Raman vibration...
N‐type Mg3(Bi, Sb)2‐based thermoelectric (TE) alloys show great promise for solid‐state power generation and refrigeration, owing to their excellent figure‐of‐merit (ZT) and using cheap Mg. However, their rigorous preparation conditions and poor thermal stability limit their large‐scale applications. Here, this work develops an Mg compensating strategy to realize n‐type Mg3(Bi, Sb)2 by a facile melting‐sintering...
Aqueous rechargeable zinc‐based batteries (ZBBs) are emerging as desirable energy storage systems because of their high capacity, low cost, and inherent safety. However, the further application of ZBBs still faces many challenges, such as the issues of uncontrolled dendrite growth and severe parasitic reactions occurring at the Zn anode. Herein, an amino‐grafted bacterial cellulose (NBC) film is prepared...
