| 1 | 快速热处理化学气相沉积法制备用于电子产品热管理的轻质柔性石墨烯显示文摘下一代电子产品的飞速发展对热管理提出了更高的要求。初始石墨烯的导热性是铜的13倍。本文通过快速热处理化学气相沉积(RTP-CVD)法制备了具有大sp^(2)结构域的单层、双层和多层石墨烯(SLG、BLG、FLG),进一步通过低浓度H_(2)还原制备了高导热石墨烯。在1000℃下生长25 min制备出SLG,利用拉曼光谱和透射电子显微镜(TEM)研究了石墨烯的品质。为了验证RTP-CVD法生成的石墨烯的散热能力,将其作为2TB固态硬盘的散热器,通过红外热成像仪进行了研究。结果证明,RTP-CVD生长的石墨烯用于消费电子产品的热管理测试时性能表现优异。SLG显示温度(最高)比商用铜散热器低5℃,SLG的散热能力比商用铜散热器快200倍左右。综上,利用RTP-CVD法制备的轻质的柔性石墨烯可以成为下一代5G设备和消费电子产品热管理的更好选择。 | Satendra Kumar Manoj Goswami Netrapal Singh Uday Deshpande Surender Kumar N.Sathish | 2023 | 新型炭材料(中英文)2023，38，3： | 0 |
| 2 | Smart-Grid Monitoring using IoT with Modified Lagranges Key Based Data Transmission显示文摘One of the recent advancements in the electrical power systems is the smart-grid technology.For the effective functioning of the smart grid,the process like monitoring and controlling have to be given importance.In this paper,the Wireless Sensor Network(WSN)is utilized for tracking the power in smart grid applications.The smart grid is used to produce the electricity and it is connected with the sensor to transmit or receive the data.The data is transmitted quickly by using the Probabilistic Neural Network(PNN),which aids in identifying the shortest path of the nodes.While transmitting the data from the smart grid to the(Internet of Things)IoT web page,it is secured by introducing the secret keys between the neighbouring nodes through the process of key-management.In this method,the combination of Lagrange’s theorem and the Location Based Key(LBK)management is used for better security performance.This approach deli-vers optimal performance in terms of security,throughput,packet loss and delay,which are comparatively better than the existing methods. | C.K.Morarji N.Sathish Kumar | 2023 | Intelligent Automation & Soft Computing2023，，3： | 0 |
| 3 | Analysis of Efficient 32 Bit Adder Using Tree Grafting Technique显示文摘Adder with high efficiency and accuracy is the major requirement for electronic circuit design.Here the optical logic gate based adder circuit is designed for better performance analysis of optical input signals varied with the wavelength.Efficiency of the adder can be improved by increasing the speed of operation,reducing the complexity and power consumption.To maintain the high efficiency with accuracy,a new combination of adder has been proposed and tested in this work.A new adder by combining the logics of Brent Kung,Sklansky and Kogge Stone adders by Tree Grafting Technique(BSKTGT)has been tested along with individual Brent Kung,Sklansky,Kogge Stone,Knowles,Han Carlson and Ladner Fischer adders.All the existing and proposed adders have been designed and tested for efficiency with the help of Cadence platform with 45 nm technology.Efficiency in terms of Size reduction,Power reduction,Power Delay Product(PDP)and accuracy in adding 8 bit,16 bit and 32 bit values had been tested for all the adders and found that the 32 bit BSKTGT adder performed well in all aspects and have produced better efficiency with the power consumption of 52.512426μW with 3.16%of power saving over Brent Kung adder,utilised an area of 631.191 with 8.55%reduction over Kogge Stone Adder,has the cell count of 132 which is 10.61%reduction over Brent Kung Adder and PDP value of 122.6695 J,which is 0.46%less than that of the Han Carlson Adder. | R.Gowrishankar N.Sathish Kumar | 2023 | Intelligent Automation & Soft Computing2023，，1： | 0 |
