Polymer Field‐Effect Transistors
In article number 2306010, Jian Pei and co‐workers demonstrate ideal and environmentally stable charge transport in n‐type polymer field‐effect transistors. The fabricated transistors exhibit high electron mobility and near 100% reliability factors and remain robust after being stored in air for more than 300 days and immersed in water or acetone.
Realizing ideal charge transport in field‐effect transistors (FETs) of conjugated polymers is crucial for evaluating device performance, such as carrier mobility and practical applications of conjugated polymers. However, the current FETs using conjugated polymers as the active layers generally show certain non‐ideal transport characteristics and poor stability. Here, ideal charge transport of n‐type...
The development of coordination polymers with π‐d conjugation (CCPs) provides ide prospects for exploring the next generation of environmental‐friendliness energy storage systems. Herein, the synthesis, experimental characterizations, and Na‐ion storage mechanism of π‐d CCPs with multiple‐active sites are reported, which use quinone‐fused aza‐phenazine (AP) and aza‐phenazin (AP) as the organic ligands...
Helicobacter pylori (H. pylori) infection has been the leading cause of gastric cancer development. In recent years, the resistance of H. pylori against antibiotic treatment has been a great challenge for most countries worldwide. Since biofilm formation is one of the reasons for the antibiotic resistance of H. pylori, and phototherapy has emerged as a promisingly alternative antibacterial treatment,...
Asymmetric plasmonic hierarchical nanostructures (HNs) are of great significance in optics, catalysis, and sensors, but the complex growth kinetics and lack of fine structure design limit their practical applications. Herein, a new atom absorption energy strategy is developed to achieve a series of Au–Ag HNs with the continuously tuned contact area in Janus and Ag island number/size on Au seeds. Different...
Triple ionic and electronic conductivity (TIEC) in cathode materials for protonic ceramic fuel cells (PCFCs) is a desirable feature that enhances the spatial expansion of active reaction sites for electrochemical oxygen reduction reaction. The realization of optimal TIEC in single‐phase materials, however, is challenging. A facile route that facilitates the optimization of TIEC in PCFC cathodes is...
WS2 anode materials show huge potential for fast‐charging lithium‐ion batteries (LIBs) due to the naturally good 2D diffusion pathways but suffer from large Li+ diffusion barrier energy and poor intrinsic electrical conductivity. Here, a defect‐rich atomic‐scale laminated structure of WS2 and C (D‐WS2‐C) with O doping and enlarged interlayer distance from 0.62 to 1.06 nm of WS2 is first fabricated,...
Excessive glutathione (GSH), which is produced owing to abnormal metabolism of tumor cells, scavenges photo‐induced reactive oxygen species (ROS) and consumes chemotherapeutic drugs, thereby attenuating the efficacy of photodynamic therapy and chemotherapy, respectively. Predominant strategies for GSH inhibition involve its chemical depletion, which only leads to a temporary therapeutic effect because...
Zn–air batteries (ZABs) are very promising for flexible energy storage, but their application is limited to the primary battery. Developing an efficient and non‐noble metal cathode toward oxygen reduction/evolution reactions (ORR/OER) is of great significance for the commercial application of rechargeable ZABs. Herein, a flexible self‐supported integrated bifunctional cathode is presented in which...
A route is developed for directly growing 2D Au polyhedron arrays with controllable exposed facets of polyhedron by utilizing the substrate‐supported 2D Au quasi‐spherical nanoparticle arrays as the Au seed arrays, which cannot be realized by traditional lithography. In the reaction system, polyvinyl pyrrolidone (PVP) plays a vital role in guiding the reduced Au atoms and stabilizing the substrate‐supported...
As a sustainable and clean water production technology, solar thermal water evaporation has been extensively studied in the past few years. One challenge is that upon operation, salt would form on surface of the solar absorbers leading to inefficient water supply and light absorption and thus much reduced water vaporization rate. To address this problem, a simple solar evaporator based on an array...
Conjugated polymers (CPs) are capable of coordinating the electron coupling phenomenon to bestow powerful optoelectronic features. The light‐harvesting and light‐amplifying properties of CPs are extensively used in figuring out the biomedical issues with special emphasis on accurate diagnosis, effective treatment, and precise theranostics. This review summarizes the recent progress of CP materials...
GaTe has recently attracted significant interest due to its direct bandgap and unique phase structure, which makes it a good candidate for optoelectronics. However, the controllable growth of large‐sized monolayer and few‐layer GaTe with tunable phase structures remains a great challenge. Here the controlled growth of large‐sized GaTe with high quality, chemical uniformity, and good reproducibility...
The rising dangers of bacterial infections have created an urgent need for the development of a new generation of antibacterial nanoagents and therapeutics. A new near‐infrared 808 nm laser‐mediated nitric oxide (NO)‐releasing nanovehicle (MoS2‐BNN6) is reported through the simple assembly of α‐cyclodextrin‐modified MoS2 nanosheets with a heat‐sensitive NO donor N,N′‐di‐sec‐butyl‐N,N′‐dinitroso‐1,4‐phenylenediamine...
Direct, low‐cost, label‐free, and enzyme‐free identification of single nucleobase is a great challenge for genomic studies. Here, this study reports that wild‐type aerolysin can directly identify the difference of four types of single nucleobase (adenine, thymine, cytosine, and guanine) in a free DNA oligomer while avoiding the operations of additional DNA immobilization, adapter incorporation, and...
Manganese‐based oxides have exhibited high promise as noncoinage alternatives to Pt/C for catalyzing oxygen reduction reaction (ORR) in basic solution and a mix of Mn3+/4+ valence is believed to be vital in achieving optimum ORR performance. Here, it is proposed that, distinct from the most studied perovskites and spinels, Mn‐based mullites with equivalent molar ratio of Mn3+ and Mn4+ provide a unique...
Combining photothermal therapy (PTT) with clinical technology to kill cancer via overcoming the low tumor targeting and poor therapy efficiency has great potential in basic and clinical researches.
