On account of unique characteristics, the integration of metal–organic frameworks as active materials in electronic devices attracts more and more attention. The film thickness, uniformity, area, and roughness are all fatal factors limiting the development of electrical and optoelectronic applications. However, research focused on ultrathin free‐standing films is in its infancy. Herein, a new method,...
In article number 1805294, Xiang‐Qin Liu, Jan K. Rainey, and co‐workers demonstrate that improved self‐assembled silk protein nanoparticle monodispersity in the concentrated solubilized spinning dope state correlates with dramatically improved wet‐spun recombinant aciniform silk fiber mechanical behavior. The nature and dispersity of self‐assembly in the spinning dope provides a straightforward property...
In article 1804523, Yoonjin Won and co‐workers study the control of structural defects called grain boundaries that occur during colloidal self‐assembly via an evaporative vertical deposition method. The parametric study shows that structural patterns created by the formation of grain boundaries are determined by governing mechanisms such as evaporative phenomena associated with different drying regimes...
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...
Developing injectable nanocomposite conductive hydrogel dressings with multifunctions including adhesiveness, antibacterial, and radical scavenging ability and good mechanical property to enhance full‐thickness skin wound regeneration is highly desirable in clinical application. Herein, a series of adhesive hemostatic antioxidant conductive photothermal antibacterial hydrogels based on hyaluronic...
High quality p–n junctions based on 2D layered materials (2DLMs) are urgent to exploit, because of their unique properties such as flexibility, high absorption, and high tunability which may be utilized in next‐generation photovoltaic devices. Based on transfer technology, large amounts of vertical heterojunctions based on 2DLMs are investigated. However, the complicated fabrication process and the...
In biological systems, nature enzymes work together in an efficacious way to undertake metabolic processes by confining cooperating enzymes within compartments. In article number 1804987, Yan Liu, Rong Guo, and co‐workers develop a facile and effective self‐assembly strategy for constructing an integrated artificial enzyme cascade platform based on protein‐BiPt nanochain@graphene oxide nanohybrid...
Molybdenum disulfide (MoS2), a 2D‐layered compound, is regarded as a promising anode for sodium‐ion batteries (SIBs) due to its attractive theoretical capacity and low cost. The main challenges associated with MoS2 are the low rate capability suffering from the sluggish kinetics of Na+ intercalation and the poor cycling stability owning to the stack of MoS2 sheets. In this work, a unique architecture...
The emerging field of valleytronics has boosted intensive interests in investigating and controlling valley polarized light emission of monolayer transition metal dichalcogenides (1L TMDs). However, so far, the effective control of valley polarization degree in monolayer TMDs semiconductors is mostly achieved at liquid helium cryogenic temperature (4.2 K), with the requirements of high magnetic field...
Benefiting from the advantages of organic field‐effect transistors (OFETs), including synthetic versatility of organic molecular design and environmental sensitivity, gas sensors based on OFETs have drawn much attention in recent years. Potential applications focus on the detection of specific gas species such as explosive, toxic gases, or volatile organic compounds (VOCs) that play vital roles in...
Next‐generation lithium‐ion batteries (LIBs) that satisfy the requirements for an electric vehicle energy source should demonstrate high reliability and safety for long‐term high‐energy‐density operation. This inevitably calls for a novel approach to advance major components such as the separator. Herein, a separator is designed and fabricated via application of multilayer functional coating on both...
Developing an efficient electrocatalyst for the hydrogen evolution reaction (HER) working in both acidic and alkaline solutions is highly desirable, but still remains challenging. Here, PtxNi ultrathin nanowires (NWs) with tunable compositions (x = 1.42, 3.21, 5.67) are in situ grown on MXenes (Ti3C2 nanosheets), serving as electrocatalysts toward HER. Such PtxNi@Ti3C2 electrocatalysts exhibit excellent...
Spider silks are desirable materials with mechanical properties superior to most synthetic materials coupled with biodegradability and biocompatibility. In order to replicate natural silk properties using recombinant spider silk proteins (spidroins) and wet‐spinning methods, the focus to date has typically been on modifying protein sequence, protein size, and spinning conditions. Here, an alternative...
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...
A new method for top‐down, one‐pot, gram‐scale production of high quality nanographene by incubating graphite in a dilute sodium hypochlorite solution at only 40 °C is reported here. The produced sheets have only 4 at% oxygen content, comparable with nanographene grown by chemical vapor deposition. The nanographene sheets are covalently functionalized using a nondestructive nitrene [2+1] cycloaddition...
Nanozymes provide new opportunities for facilitating next generation artificial enzyme cascade platforms. However, the fabrication of high‐performance integrated artificial enzyme cascade (IAEC) bioplatforms based on nanozymes remains a great challenge.

Molecular recognition is a crucial driving force for molecular self‐assembly. In many cases molecules arrange in the lowest energy configuration following a lock‐and‐key principle. When molecular flexibility comes into play, the induced‐fit effect may govern the self‐assembly.

Short circulation time and off‐target toxicity are the main challenges faced by small‐molecule chemotherapeutics. To overcome these shortcomings, an albumin‐binding peptide conjugate of chemotherapeutics is developed that binds specifically to endogenous albumin and harnesses its favorable pharmacokinetics and pharmacodynamics for drug delivery to tumors. A protein‐G‐derived albumin‐binding domain...
