In Situ Chemical Modulation of Graphitization Degree of Carbon Fibers and Its Potassium Storage Mechanism

Advanced Science, Год журнала: 2024, Номер 11(23)

Опубликована: Апрель 1, 2024

Abstract Graphite is considered to be the most auspicious anode candidate for potassium ion batteries. However, inferior rate performances and cycling stability restrict its practical applications. Few studies have investigated modulating graphitization degree of graphitic materials. Herein, a nitrogen‐doped carbon‐coated carbon fiber composite with tunable (CNF@NC) through etching growth, in‐situ oxidative polymerization, subsequent carbonization process reported. The prepared CNF@NC abundant electrochemical active sites rapid K + /electron transfer pathway, can effectively shorten distance promote insertion/removal . Amorphous domains short‐range curved graphite layers provide ample mitigation spaces storage, alleviating volume expansion highly graphitized CNF during repeated insertion/de‐intercalation. As expected, CNF@NC‐5 electrode presents high initial coulombic efficiency (ICE) 69.3%, an unprecedented reversible volumetric capacity 510.2 mA h cm −3 at 0.1 A g −1 after 100 cycles mass‐capacity 294.9 storage mechanism reaction kinetic analysis are studied by combining first‐principles calculation. It manifests that in adsorption‐insertion‐insertion (i.e., “1+2” model). solid electrolyte interphase (SEI) film forming also detected.

Engineering Bacillus Spores to Display Nicotine Oxidase: In Situ Specific and Sensitive Nicotine Detection

ACS Sensors, Год журнала: 2025, Номер unknown

Опубликована: Май 6, 2025

Nicotine exposure poses a significant public health challenge, necessitating highly sensitive and real-time detection methods. This study presents novel live electrochemical biosensor (EN@FeSe@MHCS/GCE) by integrating synthetic biology materials engineering. A genetically engineered NOX mutant-with 9.5-fold enhanced activity thermal stability (Tm = 75 °C) was displayed on Bacillus subtilis spores via genomic integration. The FeSe@MHCS composite electrode, features hierarchical porous 3D nanoflower structure (specific surface area: 196.8 m2·g-1, pore size: 8.46 nm) hydrophilicity (contact angle ≈ 15°), enabling rapid electron transfer enzyme stabilization. As expected, the achieved an ultralow limit (0.25 nM) for nicotine H2O2-mediated signal amplification, with minimal matrix interference (recovery: 98 ± 1.36-107% 2.72 in blood/urine), exceptional (98% 1.78 current retention after 14 days) reproducibility RSD of 0.62% across different electrode batches, demonstrating its efficacy as monitoring tool. Electrochemical impedance spectroscopy (EIS) confirmed low charge resistance (<125 Ω), while differential pulse voltammetry (DPV) demonstrated linear response (R2 > 0.97) concentrations. integration spore-displayed eliminates reliance bacterial growth complex genetic circuits, offering robust platform monitoring. work successfully validates proof-of-concept developing into sensor, advances enzyme-based sensing provides blueprint biosensors targeting diverse analytes.
