Abstract All-solid-state batteries (ASSBs) are pursued due to their potential for better safety and high energy density. However, the density of cathode ASSBs does not seem be satisfactory low utilization active materials (AMs) at loading. With small amount solid electrolyte (SE) powder in cathode, poor electrochemical performance is often observed contact loss non-homogeneous distribution AMs SEs, leading tortuosity limitation lithium electron transport pathways. Here, we propose a novel...
Although three-dimensional (3D) printing techniques are used to mimic macro- and micro-structures as well multi-structural human tissues in tissue engineering, efficient target regeneration requires bioactive 3D scaffolds. In this study, we developed a bone morphogenetic protein-2 (BMP-2)-immobilized polycaprolactone (PCL) scaffold with leaf-stacked structure (LSS) (

Abstract Purpose Unethical attempts to misuse and overdose opioids have led strict prescription limits, necessitating frequent hospital visits prescriptions for long-term severe pain management. Therefore, this study aimed develop a prototype wearable device that facilitates the extended delivery of opioid drugs while incorporating abuse-deterrent functionality, referred as abuse deterrent (ADD). Methods The ADD was designed fabricated using 3D-printed components, including reservoirs drug...
In the domain of tissue engineering and regenerative medicine, artificial replacements have been developed as viable options for esophageal reconstruction serve alternatives to traditional surgical procedures. Restoration smooth muscle functionality is crucial in regeneration. We evaluated efficacy reconstructions an animal model, using tissue-engineered films with a leaf-stacked structure (FLSS), seeded mesenchymal stem cells (MSCs), which were genetically modified myogenic genes....
Despite advances in surgical techniques for tendon injuries and improvements rehabilitation, the challenge of achieving sufficient regeneration preventing postoperative tissue adhesions persists orthopedic surgeons. In this study, we developed a multilayer film with platelet-derived growth factor-BB (PDGF-BB)-immobilized leaf-stacked structure (LSS) layer (bioactive layer) an alginate (antiadhesive on both sides PCL (PDGF/FLSS-Alg). The porous LSS was fabricated using heating-cooling method...
<title>Abstract</title> For nearly half a century, composite air electrode architectures based on an oxygen-ion conducting Gd<sub>0.1</sub>Ce<sub>0.9</sub>O<sub>2–δ</sub> (GDC) electrolyte phase and catalytically-active, electronically conductive second have dominated solid-oxide electrochemical cell (SOC) design. This strategy maximizes three-phase boundary density reduces electrode/electrolyte interfacial resistance, leading to exceptionally durable, high-performance devices. While this...
Abstract CRISPR (clustered regularly interspaced short palindromic repeats)–Cas9 (CRISPR-associated protein 9)-based gene editing via homologous recombination (HR) enables precise correction and insertion. However, its low efficiency poses a challenge due to the predominance of nonhomologous end-joining during DNA repair processes. Although numerous efforts have been made boost HR efficiency, there remains critical need devise novel method that can be universally applied across cell types in...
A series of perylene-based donor-acceptor-donor (D-A-D) compounds, 3,9-bis(p-(R)-diphenylamino)perylene (R: CN (2a), F (2b), H (2c), Me (2d), and OMe (2e)), was synthesized using 3,9-dibromoperylene with p-(R)-diphenylamine, the intramolecular charge transfer (ICT) on D-A-D system regard to electron push-pull substituent effect investigated. By introducing various p-(R)-diphenylamine derivatives electron-donating or electron-withdrawing R groups, energy band gaps compounds were...
The mechanofluorochromism is related to the optical properties according electron push–pull substituent effect. As intramolecular charge transfer decreases, strong intermolecular interactions occur, leading mechanofluorochromism.
Protective surface coatings on Si anodes are promising for improving the electrochemical performance of lithium-ion batteries (LIBs). Nevertheless, most coating materials have severe issues, including low initial coulombic efficiency, structural fracture, morphology control, and complicated synthetic processing.
