The development of highly conductive fibril‐type textile electrodes is crucial for the advancement of various smart wearable electronics including high‐performance energy storage devices. To achieve this goal, it is essential to convert insulating textiles into conductive counterparts while maintaining flexibility and porosity. Additionally, the incorporation of electrochemically active components into textile conductors enables tailor‐made textile energy electrodes for specific applications. Thus, textile conductors act not only as conductors but also as energy reservoirs for energy‐active components, providing a facile electron transfer network. However, textile conductors fabricated by most existing methods face challenges such as low conductivity, blockage, and brittleness. One approach to overcome these problems is to utilize interfacial interactions between individual components and textiles. Conductive nanoparticle assembly and electrodeposition based on such rational design result in highly conductive, flexible, and large surface area textile conductors. The subsequent guided assembly of active components creates high‐performance textile energy electrodes. This perspective describes how interfacial interaction‐based assembly can enhance the performance of textile conductors and textile energy electrodes. It also explores various conductor preparation approaches and recent advances in the field for applications in supercapacitors and lithium‐ion batteries.

Abstract Stretchable elastomer‐based electrodes are considered promising energy storage electrodes for next‐generation wearable/flexible electronics requiring various shape designs. However, these elastomeric electrodes suffer from the limited electrical conductivity of current collectors, low charge storage capacities, poor interfacial interactions between elastomers and conductive/active materials, and lack of shape controllability. In this study, we report hierarchically micro/nano‐wrinkle‐structured elastomeric electrodes with notably high energy storage performance and good mechanical/electrochemical stabilities, simultaneously allowing various form factors. For this study, a swelling/deswelling‐involved metal nanoparticle (NP) assembly is first performed on thiol‐functionalized polydimethylsiloxane (PDMS) elastomers, generating a micro‐wrinkled structure and a conductive seed layer for subsequent electrodeposition. After the assembly of metal NPs, the conformal electrodeposition of Ni and NiCo layered double hydroxides layers with a homogeneous nanostructure on the micro‐wrinkled PDMS induces the formation of a micro/nano‐wrinkled surface morphology with a large active surface area and high electrical conductivity. Based on this unique approach, the formed elastomeric electrodes show higher areal capacity and superior rate capability than conventional elastomeric electrodes while maintaining their electrical/electrochemical properties under external mechanical deformation. This notable mechanical/electrochemical performance can be further enhanced by using spiral‐structured PDMS (stretchability of ~500%) and porous‐structured PDMS (areal capacity of ~280 μAh cm−2).

Ciliated foregut cyst is a relatively rare disease; thus, most reports are in the form of case studies. This benign cyst is usually found in the mediastinum and account for approximately 20% of all mediastinal masses. However, it is rarely found in the hepatobiliary and peripancreatic regions. Approximately 20 cases of ciliated foregut cysts involving the pancreas have been reported in the Enlgish literature. Here, we present a case of ciliated foregut cyst that occurred in the tail of the pancreas in a 29-yearold female. The patient’s ultrasonography, CT, and MRI findings are presented, along with a review of the literature.

Abstract The effective spatial distribution and arrangement of electrochemically active and conductive components within metal oxide nanoparticle (MO NP)‐based electrodes significantly impact their energy storage performance. Unfortunately, conventional electrode preparation processes have much difficulty addressing this issue. Herein, this work demonstrates that a unique nanoblending assembly based on favorable and direct interfacial interactions between high‐energy MO NPs and interface‐modified carbon nanoclusters (CNs) notably enhances the capacities and charge transfer kinetics of binder‐free electrodes in lithium‐ion batteries (LIBs). For this study, carboxylic acid (COOH)‐functionalized carbon nanoclusters (CCNs) are consecutively assembled with bulky ligand‐stabilized MO NPs through ligand‐exchange‐induced multidentate binding between the COOH groups of CCNs and the surface of NPs. This nanoblending assembly homogeneously distributes conductive CCNs within densely packed MO NP arrays without insulating organics (i.e., polymeric binders and/or ligands) and prevents the aggregation/segregation of electrode components, thus markedly reducing contact resistance between neighboring NPs. Furthermore, when these CCN‐mediated MO NP electrodes are formed on highly porous fibril‐type current collectors (FCCs) for LIB electrodes, they deliver outstanding areal performance, which can be further improved through simple multistacking. The findings provide a basis for better understanding the relationship between interfacial interaction/structures and charge transfer processes and for developing high‐performance energy storage electrodes.

Abstract Effective incorporation of conductive and energy storage materials into 3D porous textiles plays a pivotal role in developing and designing high‐performance energy storage devices. Here, a fibril‐type textile pseudocapacitor electrode with outstanding capacity, good rate capability, and excellent mechanical stability through controlled interfacial interaction‐induced electroplating is reported. First, tetraoctylammonium bromide‐stabilized copper sulfide nanoparticles (TOABr‐CuS NPs) are uniformly assembled onto cotton textiles. This approach converts insulating textiles to conductive textiles preserving their intrinsically porous structure with an extremely large surface area. For the preparation of textile current collector with bulk metal‐like electrical conductivity, Ni is additionally electroplated onto the CuS NP‐assembled textiles (i.e., Ni‐EPT). Furthermore, a pseudocapacitive NiCo‐layered double hydroxide (LDH) layer is subsequently electroplated onto Ni‐EPT for the cathode. The formed NiCo‐LDH electroplated textiles (i.e., NiCo‐EPT) exhibit a high areal capacitance of 12.2 F cm−2 (at 10 mA cm−2), good rate performance, and excellent cycling stability. Particularly, the areal capacity of NiCo‐EPT can be further increased through their subsequent stacking. The 3‐stack NiCo‐EPT delivers an unprecedentedly high areal capacitance of 28.8 F cm−2 (at 30 mA cm−2), which outperforms those of textile‐based pseudocapacitor electrodes reported to date.

Inflammatory myofibroblastic tumors (IMTs) are rare. They are characterized by myofibroblastic spindle cell proliferation with a varying degree of inflammatory cell infiltration. IMT can occur in any anatomic location but has been reported in the lung, mesentery, and omentum, mainly in children or young adults. It rarely occurs in the pancreas and is often difficult to distinguish from other tumors, including some malignant ones. Therefore, it can be challenging to make a radiological diagnosis of IMT. Here, we present a case of IMT that occurred in the pancreas head of a middle-aged female. The patient’s ultrasonography, computed tomography, and magnetic resonance imaging findings are presented along with a review of the literature.

Biofuel cells offer biocompatibility and operation at mild conditions, but application is limited by relatively low output power. Here the authors use layer-by-layer assembly for glucose oxidase-coated metallic cotton fibers for use as electrodes in a hybrid biofuel cell to achieve high output power.

With ligand-mediated layer-by-layer assembly between metal nanoparticles and small organic molecules, the authors prepare metallic paper electrodes for supercapacitors with high power and energy densities. This approach could be extended to various electrodes for portable/wearable electronics.
