Recently, Prof. Zhu Hongwei from Tsinghua University School of Materials made progress in the application of graphene technology. One research paper and two review papers were published in "ACS Nano (Impact Factor: 12.88)" and "Advanced Materials "(Advanced Materials, Impact Factor: 17.49). The first author of the article are 2012 PhD students of Material College, Yang Tingting, Sun Pengzhan and 2013 graduate doctoral student Li Xinming. In "Tactile sensing system based on arrays of graphene woven microfabrics: electromechanical behavior and electronic skin applications" (ACS Nano 2015, DOI: 10.1021 / acsnano.5b03851 In the dissertation, the research group proposed a new idea to realize highly sensitive and flexible strain sensing of graphene, which composites graphene and super-elastic ultra-thin polymer materials to form a flexible, thin and strain-sensitive strain sensor. By constructing a sensor array, the electronic skin function of sensing distributed pressure can be realized, and weak physiological signals such as pulse and voice can be detected stably and reliably, which are expected to be applied to fields such as mobile medical devices and wearable devices. Recent developments in graphene-based membranes: structure, mass transport mechanism and potential applications (Adv. Mater. 2015, DOI: 10.1002 / adma.), the research group focused on the unique structural features of graphene materials and their different mass transfer behavior from those of traditional permeable membrane materials. The research group reviewed the relevant experimental findings and theoretical results on the mass transfer characteristics of graphene permeable membrane materials. , Separation, desalination, proton exchange and energy storage applications are prospected. By summarizing the research results of our group and other groups, the mass transfer characteristics of three types of graphene film materials (ideal graphene single crystal film, nanoporous graphene and graphene oxide permeable film) are systematically analyzed, and their potential applications and their facing Opportunities and challenges. Graphene application technology The article "Carbon / silicon heterojunction solar cells: State of the art and prospects" (Adv. Mater. 2015, 27, 6549 6574) / Semiconductor heterojunction photovoltaic model, reviewed the R & D process and the latest research progress of C / Si heterojunction solar cells. In order to enhance the performance of solar cells, several key electrical and optical design techniques (including chemical modification , Passivation of interface, antireflective coating and surface texturing, etc.), the potential applications of carbon / silicon heterojunction and future trends are prospected. The optoelectronic model is expected to play a multitude of key roles in portable devices and lightweight film products as a new source of energy in devices such as smartphones, mobile devices and medical monitoring equipment. In recent years, Zhu Hongwei's research group has focused on the controllable preparation and properties of graphene materials. The academic issues include structural design, photoelectric conversion, flexible devices, and adsorption filtration. By controlling the surface / interfacial interaction of graphene and other materials, the properties of graphene in the applications of nano-energy, nano-exploration and nano-environment are explored. The above research has been funded by major projects of Beijing Science and Technology Plan, National Natural Science Foundation of China, State Key Laboratory of New Ceramics and Fine Arts, and other projects.
The Charcoal mangal grill is a kind of barbecue grill that uses charcoal as fuel to do smokeless barbecue, and it is the most widely used grill. This mangal grill will be perfect choice for camping, backpacking, picnics, tailgate parties, camping, trailers, parks, etc. This mangal grill is carefully cast from rust-resistant stainless steel, which ensures that the grill won`t rust and be easy to clean after long-term use. Anti-slip rubber feet can make the barbecue grill more stable on the floor. This charcoal grill features combustion vents to ensure enough oxygen to enter and allow heat to spread evenly to the surface of the cooking grate, which is suitable for barbecuing hamburgers, kebabs, steaks and more.
