“…Distributing and sending contracts on the Internet of ings host works directly to limit the debugging of shared platform data recovery processes, making it possible for Internet host access due to various types of commitments. In the case of unknown logistics distribution centers, sending data back to the natural transmission environment helps, on the one hand, to obtain cloud computing systems directly, and on the other hand, it is better to use hierarchical storage logistics distribution information [17,18].…”

Based on the concept of market sharing, the author has developed Internet technology-based logistics distribution data exchange to control the cost of shipping to benefit the transfer for new types of management and operations. Investigate the needs of export shipments, such as external management responsibilities, requirements of management responsibilities, data recovery, and data recovery requirements, based on the current state of the shared platform model integration, and determine the business model. Based on this, three types of IoT cloud, such as single-center multiterminal, multicenter multiterminal, and data and application layer, can be completed and the Internet of Things can be defined by education. About the use of the cost of distribution, the transportation contract is to identify the needs of Internet technology-based logistics distributions and complete the construction of Internet technology-based logistics distribution information exchange platform. The results of the experiment showed that the results recorded in the test group did not differ from the actual results only twice, the level of difference was small, and the mean error was less than 1%. In terms of logistics distribution exposure, the average level of the assessment group is significantly higher than that of the management group, with a minimum collection rate of 90.07%, while the minimum value of the control group is as low as 76.32%. Compared with blockchain-based integration, Internet of Things technology-enabled sharing platforms can capture real-time data, transfer data, monitor shipping costs, and improve management and operations.

Detection of warning signal of particulate emission on the basis of fixed threshold in real-time using a lidar system

Monitoring pollutant emissions in an urban area is of primary importance in order to guarantee high levels of human health (by reducing the impact of respiratory diseases on urban inhabitants) and good preservation of objects (such as historical sites or buildings). The European Environment Agency (EEA) has established that the maximum concentration of PM2.5 concentration for long-term exposure is 10 μg/m3. By measuring the light that has been backscattered by atmospheric particulates, the lidar technique seems to be a valid method to provide a warning signal when a particulate concentration threshold is exceeded. In addition, the lidar system can also provide information about the distance at which the particulate threshold is exceeded. In this research measurements of traffic-originated particulate in the area near the University of Rome “Tor Vergata” is analysed at different times on a weekday to obtain continuous monitoring of its backscattering coefficient, values of particulate concentration and details about time and distance from the lidar system at which a warning signal is provided. The University of Rome “Tor Vergata” is in an area where traffic is very heavy, so high pollutant concentration values are to be expected.

“…Although the filter was able to remove almost all the particulate matter, the issue of using toxic and non-ecofriendly material is still present. Other scientists have used PLA/PMMA composite nanofibers to solve the fine particle matter issue and claim that they removed 99.5% of PM2.5 using synthetic stimulations [13]. Liu et al [14] developed a superhydrophobic filter using a mix of synthetic polymers and they were able to remove up to 96% of the PM2.5.…”

Particulate matter (PM) pollution is a significant environmental and public health issue globally. Exposure to high levels of PM, especially fine particles, can have severe health consequences. These particles can come from a variety of sources, including natural events like dust storms and wildfires, as well as human activities such as industrial processes and transportation. Although an extensive development in air filtration techniques has been made in the past few years, fine particulate matter still poses a serios and dangerous threat to human health and to our environment. Conventional air filters are fabricated from non-biodegradable and non-ecofriendly materials which can cause further environmental pollution as a result of their excessive use. Nanostructured biopolymer aerogels have shown great promise in the field of particulate matter removal. Their unique properties, renewable nature, and potential for customization make them attractive materials for air pollution control. In the present review, we discuss the meaning, properties, and advantages of nanostructured aerogels and their potential in particulate matter removal. Particulate matter pollution, types and sources of particulate matter, health effect, environmental effect, and the challenges facing scientists in particulate matter removal are also discussed in the present review. Finally, we present the most recent advances in using nanostructured bioaerogels in the removal of different types of particulate matter and discuss the challenges that we face in these applications.
