Graphene nanoribbons (GNRs) are promising in nanoelectronics for their quasi‐1D structures with tunable bandgaps. The methods for controllable fabrication of high‐quality GNRs are still limited. Here a way to generate sub‐5‐nm GNRs by annealing single‐walled carbon nanotubes (SWCNTs) on Cu(111) is demonstrated. The structural evolution process is characterized by low‐temperature scanning tunneling...
The problem in d‐band center modulation of transition metal‐based catalysts for the rate‐determining steps of oxygen conversion is an obstacle to boost the electrocatalytic activity by accelerating proton coupling. Herein, the Co doping to FeP is adopted to modify the d‐band center of Fe. Optimized Fe sites accelerate the proton coupling of oxygen reduction reaction (ORR) on N‐doped wood‐derived carbon...
Due to its tumor homing and long serum half‐life, albumin is an ideal drug carrier for chemotherapy. For endogenous albumin hitchhiking with high cargo loading, a trimeric albumin‐binding domain (ABD), i.e., ABD‐Tri is designed by fusing an ABD with high specificity and affinity for albumin to a self‐trimerizing domain (Tri) with an additional cysteine residue. ABD‐Tri is highly (40 mg L−1) expressed...
Rechargeable magnesium batteries (RMBs) are considered as one of the most promising candidates for next‐generation batteries. However, the popularization of RMBs is seriously plagued due to the lack of suitable non‐nucleophilic electrolytes and the passivation of Mg anode. Herein, a novel non‐nucleophilic electrolyte is developed by introducing (s)‐1‐methoxy‐2‐propylamine (M4) into themagnesium aluminum...
Zinc oxide (ZnO) is widely used as an electron transporting layer (ETL) for organic solar cells (OSCs). Here, a low‐cost commercial water/alcohol‐soluble fluorescent conversion agent, sodium 2,2′‐([1,1′‐biphenyl]−4,4′‐diyldivinylene)‐bis(benzenesulfonate) (CBS), is incorporated into ZnO to develop a novel organic‐inorganic hybrid ETL for high‐performance OSCs. The photoinduced charge transfer from...
The Bi0.5Sb1.5Te3 (BST) thin film shows great promise in harvesting low‐grade heat energy due to its excellent thermoelectric performance at room temperature. In order to further enhance its thermoelectric performance, specifically the power factor and output power, new approaches are highly desirable beyond the common “composition‐structure‐performance” paradigm. This study introduces ferroelectric...
The fabrication of perovskite light‐emitting diodes (PeLEDs) with vacuum deposition shows great potential and commercial value in realizing large‐area display panel manufacturing. However, the electroluminescence (EL) performance of vacuum‐deposited PeLEDs still lags behind the counterparts fabricated by solution process, especially in the field of blue PeLEDs. Here, the fabrication of high‐quality...
Due to the increased integration and miniaturization of electronic devices, traditional electronic packaging materials, such as epoxy resin (EP), cannot solve electromagnetic interference (EMI) in electronic devices. Thus, the development of multifunctional electronic packaging materials with superior electromagnetic wave absorption (EMA), high heat dissipation, and flame retardancy is critical for...
The use of bacteria and their biotic components as therapeutics has shown great potential in the treatment of diseases. Orally delivered bacteria improve patient compliance compared with injection‐administered bacteria and are considered the preferred mode. However, due to the harsh gastrointestinal environment, the viability and therapeutic efficacy of orally delivered bacteria are significantly...
A promising anode material for Li‐ion batteries, silicon (Si) suffers from volume expansion‐induced pulverization and solid electrolyte interface (SEI) instability. Microscale Si with high tap density and high initial Coulombic efficiency (ICE) has become a more anticipated choice, but it will exacerbate the above issues. In this work, the polymer polyhedral oligomeric silsesquioxane‐lithium bis (allylmalonato)...
In this paper, Au@Ag nanopencil is designed as a multimodality plasmonic nanoprobe based on asymmetric etching for the detection of SCN− and ClO−. Au@Ag nanopencil with Au tip and Au@Ag rod is prepared by asymmetric tailoring of uniformly grown silver‐covered gold nanopyramids under the combined effect of partial galvanic replacement and redox reaction. By asymmetric etching in different systems,...
Enhanced Hydrogen Evolution
MoS2 nanoflowers are successfully decorated on cobalt‐containing nitrogen‐doped carbon nanotubes to form dual‐active domains (Co‐NCNTs/MoS2). The coupling of featured domains optimizes the electronic structure and triggers the bifunctional effect to balance the Volmer step, thereby increasing the reaction step efficiency and leading to a high hydrogen evolution catalytic...
The reaction kinetics of hydrogen evolution reaction (HER) is largely determined by balancing the Volmer step in alkaline media. Bifunctionality as a proposed strategy can divide the work of water dissociation and intermediates (OH* and H*) adsorption/desorption. However, sluggish OH* desorption plagues water re‐adsorption, which leads to poisoning effects of active sites. Some active sites may even...
Sodium‐ion batteries (SIBs) are promising alternatives for large‐scale energy storage owing to the rich resource and cost effectiveness. However, there are limitations of suitable low‐cost, high‐rate cathode materials for fast charging and high‐power delivery in grid systems. Herein, a biphasic tunnel/layered 0.80Na0.44MnO2/0.20Na0.70MnO2 (80T/20L) cathode delivering exceptional rate performance through...
Cu2SnS3 is a promising thermoelectric candidate for power generation at medium temperature due to its low‐cost and environmental‐benign features. However, the high electrical resistivity due to low hole concentration severely restricts its final thermoelectric performance. Here, analog alloying with CuInSe2 is first adopted to optimize the electrical resistivity by promoting the formation of Sn vacancies...
Ultrathin 2D organic nanosheets (2DONs) with high mobility have received tremendous attention due to thickness of few molecular layers. However, ultrathin 2DONs with high luminescence efficiency and flexibility simultaneously are rarely reported. Here, the ultrathin 2DONs (thickness: 19 nm) through the modulation of tighter molecular packing (distance: ≈3.31 Å) achievable from the incorporation of...
The metallic sodium (Na) is characterized by high theoretical specific capacity, low electrode potential and abundant resources, and its advantages manifests itself as a promising candidate anode of sodium metal batteries (SMBs). However, the vaporization during the plating/stripping or uncontrolled growth of sodium dendrites in sodium metal anodes (SMAs) has posed major challenges to its practical...
Printed flexible electronics have emerged as versatile functional components of wearable intelligent devices that bridge the digital information networks with biointerfaces. Recent endeavors in plant wearable sensors provide real‐time and in situ insights to study phenotyping traits of crops, whereas monitoring of ethylene, the fundamental phytohormone, remains challenging due to the lack of flexible...
Platinum (Pt) drugs are widely used in clinic for cancer therapy, but their therapeutic outcomes are significantly compromised by severe side effects and acquired drug resistance. With the emerging immunotherapy and imaging‐guided cancer therapy, precise delivery and release of Pt drugs have drawn great attention these days. The targeting delivery of Pt drugs can greatly increase the accumulation...
Thrombotic diseases have a high rate of mortality and disability, and pose a serious threat to global public health. Currently, most thrombolytic drugs especially protein drugs have a short blood‐circulation time, resulting in low thrombolytic efficiency. Therefore, a platelet membrane (Pm) cloaked nanotube (NT‐RGD/Pm) biomimetic delivery system with enhanced thrombolytic efficiency is designed. Nanotubes...
