I courtyard Professor Wu Guanglei's team《 Nano-Micro Letter 》Published the latest research results

Recently, Professor Wu Guanglei from the energy and Environmental Materials Research Institute of our university published the title "construction of 1D heterostructure" in nano micro letter, a top international journal NiCo@C /ZnO nanood with enhanced microwave absorption ". The first author of this paper is Wang Jianwei, a 19 grade postgraduate. Qingdao University is the only communication unit. Professor Wu Guanglei is an independent correspondent author.

With the development of 5g technology, electronic equipment relying on electromagnetic wave as information carrier is widely used in various fields. However, electromagnetic wave not only promotes the development of human society, but also brings radiation pollution that can not be ignored. Electromagnetic wave absorbing material Absorbing materials can absorb the electromagnetic wave energy projected on its surface, and convert it into other forms such as heat energy through the dissipation mechanism of materials, so as to effectively absorb and attenuate electromagnetic waves. However, simple synthesis process and low cost are still the difficulties and key points restricting the development of electromagnetic wave absorbing materials. To solve the above problems, Professor Wu Guanglei's team has developed a series of structural design methods Considering the attenuation mechanism, one-dimensional (1D) heterostructures derived from Nico LDHs with excellent absorbing properties are constructed NiCo@C /ZnO nanorod composites: on the one hand, the gap between layers is used to adjust the impedance matching effect of the material; on the other hand, the synergistic effect between dielectric and magnetic loss materials is used to attenuate the electromagnetic wave in the material, so as to obtain the high-performance absorbing material with low load, high loss and controllable electromagnetic parameters, This research provides a new idea for the development of new absorbing devices

Professor Wu Guanglei has been engaged in the research and development of new dielectric micro nano devices and electromagnetic materials for a long time. In recent years, a series of important scientific research achievements have been achieved under the support of Shandong Provincial Colleges and universities youth talent introduction and education team project, Provincial Outstanding Youth Fund and provincial Taishan Scholars and young experts. Since 2021, Professor Wu Guanglei was selected as the world's top 100000 scientists announced in 2021 (ranking 29352); the team added 1 horizontal project of technology development and 1 horizontal project of technical service; 2 second prizes of Shandong provincial excellent graduate achievement award in 2021; 2 national scholarships for master's degree in 2021; 1 scholarship for president of Qingdao University in 2021; 5 people won first-class scholarship for graduate students of Qingdao University, and the rest were second-class graduate students scholarship; One national invention patent was authorized; With Qingdao University as the first unit, independent correspondents have published a number of academic papers in high-level international journals, including more than 20 papers in the category I area of the Chinese Academy of Sciences, They include nano micro lett (13 (2021) 175, impact factor: 16.419, chem eng J (414 (2021) 128875419 (2021) 130019420 (2021) 129907421 (2021) 129960422 (2021) 130079429 (2022) 132253, impact factor: 13.273, carbon (186 (2022) 262-272, impact factor: 9.594), "Mater today physics" (20 (2021) 100475, impact factor: 9.298), "components Part B" (225 (2021) 109306, impact factor: 9.078), etc.
