Self‐Wrinkling Polymer Films
In article number 2311679, Han‐Yu Hsueh and co‐workers were inspired by the superglue fuming method for fingerprint collection and developed a novel interfacial‐fuming‐induced surface instability process to generate wrinkled patterns on polymeric substrates. The technique can be easily applied to architectures with complex outer morphologies and inner surfaces and has...
Inspired by the superglue fuming method for fingerprint collection, this study developed a novel interfacial‐fuming‐induced surface instability process to generate wrinkled patterns on polymeric substrates. High‐electronegativity groups are introduced on the substrate surface to initiate the polymerization of monomer vapors, such as ethyl cyanoacrylate, which results in the formation of a stiff poly(ethyl...
Discrete organometallic complexes with defined structures are proceeding rapidly in combating malignant tumors due to their multipronged treatment modalities. Many innovative superiorities, such as high antitumor activity, extremely low systemic toxicity, active targeting ability, and enhanced cellular uptake, make them more competent for clinical applications than individual precursors. In particular,...
Micromotors
With a hybrid sonoelectrode, distinctive swarming behaviors of classical micromotors in dispersion and aggregation patterns are universally tailored by modulating the applied acoustic field in a micro‐reservoir, which offers great potentials for next‐generation active detection microsystems. More information can be found in article number 2104516 by Xiaolong Lu and co‐workers.
Enabled by active motion of microrobots, conventional biological detection and chemical analyses limited by passive diffusion can be significantly enhanced with fast testing speed and unique sensitiveness. However, controlled release and precise enrichment of microrobot swarms are still difficult to accomplish and thus prohibit them away from practical applications. Here, an efficient and versatile...
In article number 2003678, Xiaolong Lu, Wenjuan Liu, and co‐workers report dandelion‐like microswarms assembled from tubular micromotors, which are capable of performing ultrafast growth and locomotion. With the ultrasound oscillation of self‐generated bubbles, such microswarms could move at an average speed of up to 50 mm s−1 and exhibit an instant and wireless response to ultrasound stimuli.
Dynamic assembly and cooperation represent future frontiers for next generations of advanced micro/nano robots, but the required local interaction and communication cannot be directly translated from macroscale robots through the minimization because of tremendous technological challenges. Here, an ultrafast growth and locomotion methodology is presented for dandelion‐like microswarms assembled from...
Energy‐saving separation and purification of industrially important compounds with similar physical and chemical properties by novel molecular crystalline materials are of great importance and highly desired. Here a newly enlarged version of geminiarene, namely elongated‐geminiarene (ElGA), is first designed and synthesized. Taking advantages of both geminiarenes and biphenarenes, ElGA shows great...
Metal–organic frameworks (MOFs) are an interesting and useful class of coordination polymers, constructed from metal ion/cluster nodes and functional organic ligands through coordination bonds, and have attracted extensive research interest during the past decades. Due to the unique features of diverse compositions, facile synthesis, easy surface functionalization, high surface areas, adjustable porosity,...
Endophthalmitis, derived from the infections of pathogens, is a common complication during the use of ophthalmology‐related biomaterials and after ophthalmic surgery. Herein, aiming at efficient photodynamic therapy (PDT) of bacterial infections and biofilm eradication of endophthalmitis, a pH‐responsive zeolitic imidazolate framework‐8‐polyacrylic acid (ZIF‐8‐PAA) material is constructed for bacterial...
Hybrid fluorescent materials constructed from organic chelating fluorescent probes and inorganic solid supports by covalent interactions are a special type of hybrid sensing platform that has gained much interest in the context of metal ion sensing applications owing to their excellent advantages, recyclability, and solubility/dispersibility in particular, as compared with single organic fluorescent...
In article number 1805509, Ying‐Wei Yang and co‐workers construct conjugated macrocycle polymer nanoparticles consisting of dual macrocyclic rings, i.e., pillarenes and porphyrins, as alternating strut/node components in the skeleton, followed by the immobilization of Pd nanoparticles via a simple post‐treatment method. The resulting composite nanomaterials exhibit excellent stability, remarkable...
Conjugated macrocycle polymers (CMPs) integrated using the macrocyclic confinement effect make imposing restrictions feasible on the growth of metal nanoparticles with confined size and high dispersion. For a proof‐of‐concept exploration, a novel nanoscale CMP is reported, denoted as DMP[5]‐TPP‐CMP, comprising two representative types of macrocyclic compounds, i.e., pillararene and porphyrin, as alternating...
Rechargeable batteries are regarded as the most promising candidates for practical applications in portable electronic devices and electric vehicles. In recent decades, lithium metal batteries (LMBs) have been extensively studied due to their ultrahigh energy densities. However, short lifespan and poor safety caused by uncontrollable dendrite growth hinder their commercial applications. Besides, a...
Nanostructured carbon materials play essential roles in electrochemical energy storage devices. However, scalable production of high surface area carbon with a cost‐effective process while controlling the morphology is challenging. Herein, a one‐step procedure to produce carbon sheets with very high specific surface area up to 3411 m2 g−1 by direct pyrolysis of dipotassium ethylene diamine tetraacetate...
An intelligent theranostic nanoplatform based on nanovalve operated metal–organic framework (MOF) core–shell hybrids, incorporating tumorous microenvironment‐triggered drug release, magnetic resonance imaging (MRI) guidance, sustained release, and effective chemotherapy in one pot is reported. The core–shell hybrids are constructed by an in situ growth method, in which Fe3O4 particles with superior...
