A DFT investigation on interactions between lignin and ionic liquids

Abstract: The interactions of the lignin model, the lignin oligomer with degree of polymerization n = 2, with 1-butyl-3-methylimidazolium chloride ionic liquid were investigated through DFT calculations in detail. Computational results revealed that lignin dissolution in ionic liquids should be a result of the joint interactions of lignin with anion and cation of ionic liquid, and the formation of ion pair weakens the interactions between lignin and ionic liquid components. Unlike the dominant H-bonds within the lignin–anion interactions, the lignin–cation interactions involve a combination of hydrogen bond and π-stacking. These results would provide mechanistic insights and suggestions for lignocellulosic dissolution in ionic liquids.

Design of Wireless Sensor Network for Cold Storage Monitoring System

Abstract: In this paper, a monitoring system of cold storage ring is designed based on the characteristics of Zigbee wireless sensor network (WSN) and the actual situation of cold storage, which Including ZigBee network hardware and software design. The ZigBee WSN routing protocol Cluster Tree is improved, neighbor table information is drew into in the Cluster Tree algorithm, also studied the selection of nodes in neighbor table, It is beneficial to find an optimal path and reduce the delay of data transmission. The Zigbee WSN is used in the cold storage monitoring system, so it can be used for a long time with only one installation, which can solve the problems of complicated equipment and low efficiency in the traditional cold storage management. The test results show that the system meets the design requirements, so as to achieve the purpose of real-time monitoring of cold storage items.

An improved image registration and fusion algorithm

Abstract: Under the background of telemedicine, a new registration and mosaic algorithm for medical images is proposed in this paper to solve the problems of electronic noise, uneven illumination and ray scattering in the real-time medical process. The improved Retinex algorithm by trilateral filter and homomorphic filtering algorithm can enhance the image effectively in preprocessing. The improved phase correlation algorithm based on log polar transformation was used to calculate parameters, such as rotation, scaling and translation. Then, the SUSAN corner matching points were extracted in overlapping positions, the improved KD tree was used for enhancing matching efficiency. Later, matching points were purified by the improved RANSAC algorithm. Finally, images were processed by Laplacian pyramid decomposition algorithm to make the image joint seemed smooth and natural. The results of experiments and evaluation criteria confirm that the new method has high robustness in the process of medical image registration and stitching in the network.
