Conjugated polymer has the potential to be applied on flexible devices as an active layer, but further investigation is still hindered by poor conductivity and mechanical stability. Here, this work demonstrates a dopant‐enhanced conductive polymer thin film and its application in dimethyl methylphosphonate (DMMP) sensor. Among five comparable polymers this work employs, poly(bisdodecylthioquaterthiophene)...
The rational design of efficient and multifunctional electrocatalysts for energy conversion devices is one of the major challenges for clean and renewable energy transition. Herein, the local electronic structure of cobalt–platinum nanoclusters is regulated by adjacent platinum atomic site encapsulated in N‐doped hollow carbon nanotubes (PtSA–PtCo NCs/N–CNTs) by pyrolysis of melamine‐orientation‐induced...
Inadequate photo‐generated charge separation, migration, and utilization efficiency limit the photocatalytic efficiency. Herein, a MoS2/MIL‐53(Fe) photocatalyst/activator with the S‐scheme heterojunction structure is designed and the charge migration behavior is modulated by the internal electric field (IEF). The IEF intensity is enhanced to 40 mV by modulating band bending potential and the depletion...
clustered regularly interspaced short palindromic repeats (CRISPR)‐Cas systems are increasingly used in biosensor development. However, directly translating recognition events for non‐nucleic acid targets by CRISPR into effective measurable signals represents an important ongoing challenge. Herein, it is hypothesized and confirmed that CRISPR RNAs (crRNAs) in a circular topology efficiently render...
Contamination of water resources by toxic metals and opportunistic pathogens remains a serious challenge. The development of nano‐adsorbents with desired features to tackle this problem is a continuously evolving field. Here, magnetic mesoporous carbon nanospheres grafted by antimicrobial polyhexamethylene biguanidine (PHMB) are reported. Detailed mechanistic investigations reveal that the electrostatic...
The NiO‐based electrocatalytic oxygen evolution reaction (OER) of water splitting is recognized as a promising approach to produce clean H2 fuel. However, the OER performance is still low, and especially, the overpotential is larger than 200 mV at the current density of 10 mA cm−2. Herein, an Ir@IrNiO sample is prepared with single‐atom (SA) Ir4+ doping and surface metallic Ir nanoparticles loaded...
The wide applications of Ni‐rich LiNi1‐x‐yCoxMnyO2 cathodes are severely limited by capacity fading and voltage fading during the cycling process resulting from the pulverization of particles, interfacial side reactions, and phase transformation. The canonical surface modification approach can improve the stability to a certain extent; however, it fails to resolve the key bottlenecks. The preparation...
