• Strength of up to 1.1GPa graphene film to achieve large-scale, continuous production!

    Strength of up to 1.1GPa graphene film to achieve large-scale, continuous production! As two-dimensional material first to be discovered and studied, graphene has extremely excellent physical and mechanical properties, such as tensile strength inner surface theory, electrical conductivity and thermal conductivity were up 130GPa, 108Sm-1 and 5300Wm-1K- 1, it is considered the best and most promising structural and functional materials. In order to obtain graphene macro applications, the current mainstream strategy is small-sized graphene derivative (such as graphene oxide GO) to assemble the macro films, fibers, or bulk material by various methods. However

  • Graphene masks cost as little as $ 0.05! Not only can self-cleaning, but also for seawater desalination

    Graphene masks cost as little as $ 0.05! Not only can self-cleaning, but also for seawater desalination, 2019 coronavirus (COVID-19) affects more than 210 countries and regions, and mainly through respiratory droplets. In high-risk areas, patients, doctors and even ordinary people are generally the use of disposable surgical masks. However, the current ordinary surgical masks presence not self-disinfecting, reused or recycled for other uses and other issues. To deal with these used masks, most countries can only be used to deal with such medical waste incineration. Of toxic gases and carbon emissions would seriously risk

  • For three-dimensional hydrogel functionalized graphene high performance gas detection, both 3D and green synthetic!

    For three-dimensional hydrogel functionalized graphene high performance gas detection, both 3D and green synthetic! , Nitrogen dioxide (NO2) and other gas pollution has become today the field of environment and health to be solved, the development of accurate, rapid and highly sensitive detection of low concentrations of gas gas sensor is important. Reduced graphene oxide (of RGO) having a potential in the preparation of high-performance, low-cost gas sensors aspect, but there are three problems limit its practical application: 1) the graphene gas sensor response to various gases are poor selectivity; 2) the graphene sheets are stacked prone to agglomeration, leading to gas molecules in the stone

  • The liquid crystal graphene research on the New Development

    Advances in Research on the new crystal graphite eligible alkenyl, stone Tsinghua University in Shanghai Institute of TF full high X-ray small angle light scattering beamlines support of eligible important progress in the field of liquid crystal graphene research. Graphene oxide has been successfully used for high-strength fibers and films prepared graphene. Normal size graphene oxide, forming the nematic liquid crystal requires a high concentration of highly oriented, but is not suitable for high concentration of low density airgel graphene. Therefore developed a new method enables the graphene oxide crystal is formed at a low concentration prepared graphene alignment is the crux of the problem airgel. Researchers graphene oxide was added to the base solution,

  • Nature Sub Series: Ultimate photothermal effect graphene airgel

    Nature Sub Series: Ultimate photothermal effect graphene airgel, Nature sub JOURNAL: Ultimate photothermal effect graphene airgel, the final proof of the photothermal acoustic graphene airgel (PTA) efficiency, depending on their specific heat and optical properties can be achieved experimentally by lowering its mass density. A brief introduction of the sound generated in a passive optical devices, amplification, modulation, and the ability to mix sound without harmonic distortion will completely change the acoustic field. Like the conventional speaker, light thermoacoustic (PTA) allow the conversion of light to effect sound, without any moving parts and a large amount of organic electrically connected. Moreover, PT
