How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Semiconducting nanomaterials with 3D network structures exhibit various fascinating properties such as electrical conduction, high permeability, and large surface areas, which are beneficial for adsorption, separation, and sensing applications. However, research on these materials is substantially restricted by the limited trans-scalability of thei...
Heat dissipation has become increasingly important in electronics. Conventional convection cooling systems have significant material and dimensional constraints, and they have difficulty meeting the heat dissipation, miniaturization, and flexibility requirements of next-generation smart electronics. Here, we used kirigami (the traditional art of pa...
Three-dimensional porous and defect-rich nitrogen-doped nanocarbon is successfully prepared by facile pyrolysis of crab shell-derived chitin nanofiber paper, delivering promising performance in both photosensing and energy storage.
Plasmonic nanoparticles, such as gold nanoparticles (AuNPs), have been actively applied in solar vapor generation for seawater desalination and water purification, owing to their photothermal heating performances. Such nanoparticles have been frequently anchored within porous supporting materials to ensure easy handling and water absorption. Howeve...
Progress toward the concept of “a trillion sensor universe” requires sensor devices to become more abundant, ubiquitous, and be potentially disposable. Here, we report a paper-based disposable molecular sensor device constructed from a nanowire sensor based on common zinc oxide (ZnO), a wood-derived biodegradable cellulose nanofiber paper substrate...
Wood-derived materials have porous structures ranging from nano- to micro-scale which are resulted from the cellulose fiber networks and are expected to be applied as flow transport channels. This research aims to control the morphology of the porous structures within the wood-derived materials and clarify their relationship with the flow transport performance for liquids, gases, light, etc. Then, the application for novel wood-derived devices that take the advantages of the nano- to micro-scale porous structures, including the solar vapor generators, will be explored.
