Flexible thermocells for utilization of body heat
Nano Research - Tập 7 - Trang 443-452 - 2015
Plastic thermo-electrochemical cells (thermocells) involving aqueous potassium ferricyanide/ferrocyanide electrolyte have been investigated as an alternative to conventional thermoelectrics for thermal energy harvesting. Plastic thermocells that consist of all pliable materials such as polyethylene terephthalate (PET), fabrics, and wires are flexible enough to be wearable on the human body and to ......
Highly defective graphene: A key prototype of two-dimensional Anderson insulators
Nano Research - Tập 6 - Trang 326-334 - 2013
Electronic structure and transport properties of highly defective two-dimensional (2D) sp2 graphene are investigated theoretically. Classical molecular dynamics are used to generate large graphene planes containing a considerable amount of defects. Then, a tight-binding Hamiltonian validated by ab initio calculations is constructed in order to compute quantum transport within a real-space order-N ......
Atomscopic of ripple origins for two-dimensional monolayer transition metal dichalcogenides
Nano Research - - Trang 1-9 - 2023
During the development of ultrathin two-dimensional (2D) materials, the appearance of ripples has been widely observed. However, the formation mechanisms and their influences are still rarely investigated, especially their contributions to the electronic structures and optical properties. To compensate for the knowledge gap, we have carried out comprehensive theoretical studies on the monolayer WS......
Self-assembly tungsten selenide hybrid ternary MOF derived magnetic alloys via multi-polarization to boost microwave absorption
Nano Research - - Trang 1-11 - 2023
Confronted with severe electromagnetic wave pollution, the development of high-performance electromagnetic wave shielding or absorbing materials is an effective way to deal with it. Notably, double transition metal alloys and transition metal dichalcogenides have attracted extensive attention in electromagnetic wave absorption, but few reports have studied the effects of these two materials on ele......
Facile design of Au@Pt core-shell nanostructures: Formation of Pt submonolayers with tunable coverage and their applications in electrocatalysis
Nano Research - Tập 7 - Trang 410-417 - 2014
A facile design of Pt nanostructures from submonolayer to monolayer has been realized by ion adsorption-in situ electrochemical reduction on Au nanoparticles supported on multiwall carbon nanotubes (CNTs). The as prepared Au@Pt/CNTs catalysts display coverage-specific electrocatalysis. Au@Pt/CNTs with low Pt coverage is inactive towards methanol oxidation whereas it oxidizes formic acid effectivel......

Interfacial engineering of atomic platinum-doped molybdenum carbide quantum dots for high-rate and stable hydrogen evolution reaction in proton exchange membrane water electrolysis
Nano Research - Tập 16 - Trang 12186-12195 - 2023
Platinum (Pt)-based electrocatalysts remain the only practical cathode catalysts for proton exchange membrane water electrolysis (PEMWE), due to their excellent catalytic activity for acidic hydrogen evolution reaction (HER), but are greatly limited by their low reserves and high cost. Here, we report an interfacial engineering strategy to obtain a promising low-Pt loading catalyst with atomically......
Multidimensional CdS nanowire/CdIn2S4 nanosheet heterostructure for photocatalytic and photoelectrochemical applications
Nano Research - Tập 10 - Trang 2699-2711 - 2017
Nanomaterial shapes can have profound effects on material properties, and therefore offer an efficient way to improve the performances of designed materials and devices. The rational fabrication of multidimensional architectures such as one dimensional (1D)–two dimensional (2D) hybrid nanomaterials can integrate the merits of individual components and provide enhanced functionality. However, it is......
Rational design of 3D porous niobium carbide MXene/rGO hybrid aerogels as promising anode for potassium-ion batteries with ultrahigh rate capability
Nano Research - Tập 16 - Trang 2463-2473 - 2022
An effective method is designed to construct three-dimensional (3D) Nb2C/reduced graphene oxide (rGO) hybrid aerogels through a low-temperature graphene oxide (GO)-assisted hydrothermal self-assembly followed by freeze-drying and annealing. The intimately coupled Nb2C/rGO hybrid aerogel combines the advantages of large specific surface area and rich 3D interconnected porous structure of aerogel as......
Magnetic transitions in graphene derivatives
Nano Research - Tập 7 - Trang 1507-1518 - 2014
The magnetic transitions in graphene oxide (GO) have been investigated experimentally. Micron-sized GO flakes exhibit dominant diamagnetism accompanied by weak ferromagnetism at room temperature. However, when the lateral dimensions of GO flakes are reduced from micron-size to nano-size, a clear transition from dominant diamagnetism to ferromagnetism is observed. After reducing the GO chemically o......
