Cobalt-based metal–organic framework as a dual cooperative controllable release system for accelerating diabetic wound healing
Nano Research - Tập 13 - Trang 2268-2279 - 2020
Insufficient angiogenesis in the chronic wound of the diabetic is one of the most important causes that making the wound unable to heal itself. In this work, a cobalt-based metal–organic framework (ZIF-67) was introduced as a carrier for loading a pro-angiogenic small molecular drug (dimethyloxalylglycine, DMOG). To achieve a long-term angiogenic therapy on the diabetic wound beds, a dual cooperat......
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 ......
Spatial confinement of zeolitic imidazolate framework deposits by porous carbon nanospheres for dual-atom catalyst towards high-performance oxygen reduction reaction
Nano Research - Tập 16 - Trang 11464-11472 - 2023
Dual atom catalysts (DACs), are promising electrocatalysts for oxygen reduction reaction (ORR) on account of the potential dual-atom active sites for the optimized adsorption of catalytic intermediates and the lower reaction energy barriers. Herein, spatial confinement strategy to fabricate DACs with well-defined Fe, Co dual-atom active site is proposed by implanting zeolitic imidazolate framework......
Chemical-vapor-deposition-grown 2D transition metal dichalcogenides: A generalist model for engineering electrocatalytic hydrogen evolution
Nano Research - Tập 16 - Trang 101-116 - 2022
Two-dimensional (2D) transition metal dichalcogenides (TMDs) have proved to possess exceptional catalytic performance for hydrogen evolution and are considered to be an appropriate substitute for commercial Pt-based catalysts. Experimentally, chemical vapor deposition (CVD) is an extremely important technique for acquiring controllable and high-purity TMDs for electrocatalysis and modern electroni......
Diameter-dependent photoelectric performances of semiconducting carbon nanotubes/perovskite heterojunctions
Nano Research - Tập 16 - Trang 12662-12669 - 2023
The heterojunction of single-wall carbon nanotubes (SWCNTs) and perovskite quantum dots (QDs) shows excellent photodetection performances due to the combination of the advantages of high carrier mobility of SWCNTs and high absorption coefficient of perovskite QDs. However, the band structure of a SWCNT is determined by its atomic arrangement structure. How the structure of SWCNTs affects the photo......
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 ......
Upconversion nano-photosensitizer targeting into mitochondria for cancer apoptosis induction and cyt c fluorescence monitoring
Nano Research - Tập 9 - Trang 3257-3266 - 2016
Disruption of mitochondrial reactive oxygen species (mitoROS) plays a major role in cancer cell apoptosis. Here, we designed a core/shell-structured mitochondria-targeting upconversion-based nano-photosensitizer (TPP-UC(PS)) with a lanthanide-doped upconversion nanoparticle (UCNP) core coated by a photosensitizer (PS)-incorporated dense silica shell. Following irradiation with external near-infrar......
Developing hierarchical CdS/NiO hollow heterogeneous architectures for boosting photocatalytic hydrogen generation
Nano Research - Tập 15 - Trang 2003-2012 - 2021
The hierarchical binary CdS/NiO hollow heterogeneous architectures (HHAs) with p-n heterojunction are constructed by a facile microwave-assisted wet chemical process for high-efficient photocatalytic hydrogen evolution reaction (HER) from water. The asdesigned CdS/NiO HHAs are composed of hexagonal n-type CdS nanoparticles with a size in the range of 20–40 nm attaching to cubic p-type NiO hollow m......
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......
