Despite incorporation of organic groups into silica‐based aerogels to enhance their mechanical flexibility, the wide temperature reliability of the modified silicone aerogel is inevitably degraded. Therefore, facile synthesis of soft silicone aerogels with wide‐temperature stability remains challenging. Herein, novel silicone aerogels containing a high content of Si are reported by using polydimethylvinylsiloxane...
Flexible fibers and textiles featuring photothermal conversion and storage capacities are ideal platforms for solar‐energy utilization and wearable thermal management. Other than using fossil‐fuel‐based synthetic fibers, re‐designing natural fibers with nanotechnology is a sustainable but challenging option. Herein, advanced core–shell structure fibers based on plant‐based nanocelluloses are obtained...
Non‐aqueous solvents, in particular N,N‐dimethylaniline (NMP), are widely applied for electrode fabrication since most sodium layered oxide cathode materials are readily damaged by water molecules. However, the expensive price and poisonousness of NMP unquestionably increase the cost of preparation and post‐processing. Therefore, developing an intrinsically stable cathode material that can implement...
Low‐dimensional materials serving as photocatalysts favor providing abundant unsaturated active sites and shortening the charge transport distance, but the high surface energy readily causes the aggregation that limits their application. Herein, it is demonstrated that 2D covalent organic framework (COF) TpBD nanosheets are effective in the dispersion and stabilization of 0D Ni(OH)2. The COF precursor...
Li‐O2 batteries could deliver ultra‐high theoretical energy density compared to current Li‐ion batteries counterpart. The slow cathode reaction kinetics in Li‐O2 batteries, however, limits their electrocatalytic performance. To this end, MoSe2 and Ni0.85Se nanoflakes were decorated in carbon hollow nanoflowers, which were served as the cathode catalysts for Li‐O2 batteries. The hexagonal Ni0.85Se...
The nanodelivery system provides a novel direction for disease diagnosis and treatment; however, its delivery effectiveness is restricted by the short biological half‐life and inadequate tumor targeting. The immune evasion properties and homologous targeting capabilities of natural cell membranes, particularly those of cancer cell membranes (CCM), have gained significant interest. The integration...
Photocatalytic hydrogen production via water splitting is the subject of intense research. Photoinduced electron transfer (PET) between a photosensitizer (PS) and a proton reduction catalyst is a prerequisite step and crucial to affecting hydrogen production efficiency. Herein, three photoactive metal–organic framework (MOF) systems having two different PET processes where PS and Co(II) centers are...
Regulating the electronic structure of active sites and monitoring the evolution of the active component is essential to improve the intrinsic activity of catalysts for electrochemical reactions. Herein, a highly efficient pre‐electrocatalyst of iron diselenide with rich Se vacancies achieved by phosphorus doping (denoted as P‐FeSe2) for oxygen evolution reaction (OER) is reported. Systematically...
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...
Toehold‐mediated DNA circuits are extensively employed to construct diverse DNA nanodevices and signal amplifiers. However, operations of these circuits are slow and highly susceptive to molecular noise such as the interference from bystander DNA strands. Herein, this work investigates the effects of a series of cationic copolymers on DNA catalytic hairpin assembly, a representative toehold‐mediated...
Li‐O2 batteries are acknowledged as one of the most promising energy systems due to their high energy density approaching that of gasoline, but the poor battery efficiency and unstable cycling performance still hinder their practical application. In this work, hierarchical NiS2‐MoS2 heterostructured nanorods are designed and successfully synthesized, and it is found that heterostructure interfaces...
Leveraging size effects, nanoparticles of metal‐organic frameworks, nanoMOFs, have recently gained traction, amplifying their scopes in electrochemical sensing.

Stabilized Pt Clusters
In article number 2300547, Yunqian Dai and co‐workers report that they effectively stabilize 2.6 nm‐Pt clusters against sintering over 800 °C on electrospun CeO2 nanofibers decorated by CeO2 nanocubes with thermodynamic and kinetic strategy. Such clusters show superior catalytic performance toward both the hydrogenation and oxidation reactions.
Sintering is a major concern for the deactivation of supported metals catalysts, which is driven by the force of decreasing the total surface energy of the entire catalytic system. In this work, a double‐confinement strategy is demonstrated to stabilize 2.6 nm‐Pt clusters against sintering on electrospun CeO2 nanofibers decorated by CeO2 nanocubes (m‐CeO2). Thermodynamically, with the aid of CeO2‐nanocubes,...
Post‐combustion flue gas (mainly containing 5–40% CO2 balanced by N2) accounts for about 60% global CO2 emission. Rational conversion of flue gas into value‐added chemicals is still a formidable challenge. Herein, this work reports a β‐Bi2O3‐derived bismuth (OD‐Bi) catalyst with surface coordinated oxygen for efficient electroreduction of pure CO2, N2, and flue gas. During pure CO2 electroreduction,...
Transition metal catalysts are regarded as one of promising alternatives to replace traditional Pt‐based catalysts for oxygen reduction reaction (ORR). In this work, an efficient ORR catalyst is synthesized by confining Fe3C nanoparticles into N, S co‐doped porous carbon nanosheets (Fe3C/N,S‐CNS) via high‐temperature pyrolysis, in which 5‐sulfosalicylic acid (SSA) demonstrates as an ideal complexing...
Overexpressed matrix metalloproteinases, hypoxia microenvironment, and metabolic abnormality are important pathological signs of rheumatoid arthritis (RA). Designing a delivery carrier according to the pathological characteristics of RA that can control drug release in response to disease severity may be a promising treatment strategy.

The core‐void@shell architecture shows great advantages in enhancing cycling stability and high‐rate performance of Si‐based anodes. However, it is usually synthesized by template methods which are complex and environmentally unfriendly and would lead to low‐efficiency charge and mass exchange because of the single‐point van der Waals contact between the Si core and the shell. Here, a facile and benign...
Osteosarcoma (OS) is one of the most common bone malignant tumors which mainly develops in adolescents. Although neoadjuvant chemotherapy has improved the prognosis of patients, numerous chemotherapeutic challenges still limit their use. Here, inspired by the Watson–Crick base pairing in nucleic acids, hydrophobic (methotrexate) and hydrophilic (floxuridine) chemo‐drugs are mixed and self‐assembled...
Atomically thin monolayer semiconducting transition metal dichalcogenides (TMDs), exhibiting direct band gap and strong light‐matter interaction, are promising for optoelectronic devices.
