[quick news] on May 21, 2018, this "honeycomb" material can increase the battery life of mobile phones by 100 times

This "honeycomb" material can enhance the battery life of mobile phones by 100 times, no matter how high the pixel and how fast the processor is, the battery life of smart phones has always been a "dead hole" By distributing the magnetic materials into the honeycomb lattice, the new nano materials can suppress the heat generated by traditional batteries, consume less power, and store more energy between two charges For example, a five hour battery can last up to 500 hours Http:// scientists have built the world's smallest house, so small that mites cannot enter France Using a new nano robot system, scientists at femto st Institute of science built a "mini house" on a fiber as thin as human hair It's only 20 microns in size, but it has some astonishingly precise details, including front doors, windows and even tiled roofs In the Journal of Vacuum Science and technology, the researchers described in detail the process of creating a micro room The new nano robot system, called μ rooptex, uses a range of technologies, including a micro robot, a focused ion beam and a gas injection device Focused ion beams can track and cut the shape of a house like scissors Http:// ා ixzz5furje9ow new breakthrough | graphene and gold can help us test drugs and monitor cancer Recently, a study published on Science showed how to use light and graphene to control the beating of human heart cells Graphene transforms light into electricity to manipulate cells Furthermore, graphene can be used to control electricity in the brain and help treat neurodegenerative diseases such as Parkinson's disease Another material with great medical potential is gold Gold nanoparticles can not only deliver the specific drugs we need to specific organs, but also can be used to monitor cancer Https:// the University of Hong Kong awarded honorary doctorates to Ma Yun and other three people, including entrepreneurs Ma Yun, Meng Deyang and scientist Deng Qingyun, in recognition of their academic and social contributions At the 199th degree awarding ceremony on HKU campus on August 18, the chief executive of the Hong Kong SAR, Mrs Lam Cheng Yueh, who is also the supervisor of HKU, awarded honorary doctorates to three outstanding people Http:// the fifth international energy storage summit and China International Energy Storage Technology and Application Exhibition (hereinafter referred to as "esc2018") will be held in Tangshan on September 19-21, and will be held in Tangshan Nanhu International Convention and Exhibition Center Esc2018 focuses on energy storage, distributed energy, new energy electric vehicles and other core industries, and holds 11 sub forums with the theme of "wisdom due to energy storage, innovation for energy storage", so as to make the perfect combination of "exhibition" and "meeting" At that time, more than 150 speakers at home and abroad will discuss topics of high concern http://news.sciencenet.cn/htmlnews/2018/5/412584.shtm
