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...
The combination of 2D magnetic nanosheets and mesoporous carbon with unique interfaces shows considerable prospects for microwave absorption (MA). However, traditional assembly procedures make it impossible to accurately manage the assembly of magnetic nanosheets in carbon matrices. Herein, a reverse strategy for preparing complex magnetic nanosheet cores inside carbon‐based yolk–shell structures...
Molybdenum selenium (MoSe2) has tremendous potential in potassium‐ion batteries (PIBs) due to its large interlayer distance, favorable bandgap, and high theoretical specific capacity. However, the poor conductivity and large K+ insertion/extraction in MoSe2 inevitably leads to sluggish reaction kinetics and poor structural stability. Herein, Coinduced engineering is employed to illuminate high‐conductivity...
Developing efficient and durable electrocatalysts for the oxygen evolution reaction (OER) in proton exchange membrane (PEM) electrolyzers represents a significant challenge. Herein, the cobalt‐ruthenium oxide nano‐heterostructures are successfully synthesized on carbon cloth (CoOx/RuOx‐CC) for acidic OER through a simple and fast solution combustion strategy. The rapid oxidation process endows CoO...
Optimizing the adsorption free energy and promoting the active phase transition to further enhance the oxygen evolution reaction (OER) activity remain significant challenges. The adsorption free energy can be optimized by modulating the electronic structure and adjusting the crystal configuration. Meanwhile, the transformation of the active phase can be promoted by introducing strain energy. The theoretical...
Silk fibroin (SF) is a promising biomaterial for tendon repair, but its relatively rigid mechanical properties and low cell affinity have limited its application in regenerative medicine. Meanwhile, gelatin‐based polymers have advantages in cell attachment and tissue remodeling but have insufficient mechanical strength to regenerate tough tissue such as tendons. Taking these aspects into account,...
High‐voltage spinel cobalt‐free LiNi0.5Mn1.5O4 (LNMO) is one of the most promising cathode candidates for next‐generation lithium‐ion batteries (LIBs) due to its high specific capacity, high operating voltage, and low cost. However, inferior electronic conductivity, transition metal dissolution, and fast capacity degradation of LNMO, especially in high mass loading for high areal capacity, are the...
The unique structural advantage and physicochemical properties render some 2D materials emerging platforms for intracellular bioimaging, biosensing, or disease theranostics. Despite recent advances in this field, one major challenge lies in bypassing the endocytic uptake barrier to allow internalization of very large 2D materials that have longer retention time in cells, and hence greater potency...
Since the sluggish kinetic process of oxygen reduction (ORR)/evolution (OER) reactions, the design of highly‐efficient, robust, and cost‐effective catalysts for flexible metal–air batteries is desired but challenging. Herein, bimetallic nanoparticles encapsulated in the N‐doped hollow carbon nanocubes (e.g., FeCo‐NPs/NC, FeNi‐NPs/NC, and CoNi‐NPs/NC) are rationally designed via a general heat‐treatment...
In article number 1902641, Robert Y. L. Wang, Shiow‐Yi Chen, Chih‐Ching Huang, and co‐workers develop a simple one‐step dry heating process which allows the synthesis of core–shell carbon quantum dots derived from curcumin. The obtained carbon quantum dots possess excellent antiviral activity against enterovirus 71 through a complex inhibitory mechanism.
It is demonstrated that carbon quantum dots derived from curcumin (Cur‐CQDs) through one‐step dry heating are effective antiviral agents against enterovirus 71 (EV71). The surface properties of Cur‐CQDs, as well as their antiviral activity, are highly dependent on the heating temperature during synthesis. The one‐step heating of curcumin at 180 °C preserves many of the moieties of polymeric curcumin...
In this paper, electrostatically configurable 2D tungsten diselenide (WSe2) electronic devices are demonstrated. Utilizing a novel triple‐gate design, a WSe2 device is able to operate as a tunneling field‐effect transistor (TFET), a metal–oxide–semiconductor field‐effect transistor (MOSFET) as well as a diode, by electrostatically tuning the channel doping to the desired profile. The implementation...
Activatable imaging probes are promising to achieve increased signal‐to‐noise ratio for accurate tumor diagnosis and treatment monitoring. Magnetic resonance imaging (MRI) is a noninvasive imaging technique with excellent anatomic spatial resolution and unlimited tissue penetration depth. However, most of the activatable MRI contrast agents suffer from metal ion‐associated potential long‐term toxicity,...
As a characteristic trait of most tumor types, metastasis is the major cause of the death of patients. In this study, a photothermal agent based on gold nanorod is coated with metal (Gd3+)‐organic (polyphenol) network to realize combination therapy for metastatic tumors. This nanotheranostic system significantly enhances antitumor therapeutic effects in vitro and in vivo with the combination of photothermal...
Nanomedicine has been growing exponentially due to its enhanced drug targeting and reduced drug toxicity. It uses the interactions where nanotechnological components and biological systems communicate with each other to facilitate the delivery performance. At this scale, the physiochemical properties of delivery systems strongly affect their capacities. Among current delivery systems, DNA nanotechnology...
