为了减小污垢对中央空调冷水机组效率的影响，提高城市能源系统效率，提出了一种特殊的在线水处理技术（special online water treatment technology，SOWTT）。通过追踪和计算厦门数台冷水机组的趋近温度、运行效率、年耗电量和二氧化碳减排量来评估SOWTT的效果。结果表明采用SOWTT的冷水机组的趋近温度基本与新机组趋近温度数值相当，能够有效防止污垢生成。另外SOWTT能使冷水机组制冷系数（coefficient of performance，COP）值基本保持在新机COP的90%以上。如果将中国所有冷水机组都采用SOWTT，相比于每半年一次的机械式清理，能够节约50.07%的电能，经济效益显著，同时可减排大量二氧化碳，实现节能减排的目标。因此SOWTT综合效益显著，其广泛使用将会大幅提升城市能源系统效率。

High-quality, large-size CaF2 crystals are urgently needed for advanced applications such as deep ultraviolet lithography and aerospace cameras. However, growing such crystals is a challenging task in the field of crystal growth. Heat transfer, flow, and phase change processes of 3, 7, and 20 inch (1 inch =2. 54 cm) CaF2 crystals at different growth stages on the vertical Bridgman growth were conducted by numerical simulation. The results show that as the crystal size increases, the melt flow strength and the area of heat dissipation on the crucible wall increase, resulting in problems such as local depression of the melt-crystal interface, increase in the radial temperature difference, reversal of the temperature difference between the crystal edge and center, and decrease in the axial temperature gradient near the melt-crystal interface. Furthermore, this article discusses optimization strategies for growth rate and power of heater in the growth of large-size CaF2 crystals. [ABSTRACT FROM AUTHOR]

Rural resource endowment, resource combination mode and its commodification degree affect the construction of rural resilient economic system. This paper explored the hot spots and laws of international rural resource commodification research by using visual and traditional literature reading methods and taking Web of Science core collection literature as data, and finally revealed the enlightenment of this research on the practice of rural transformation and revitalization in China. The study points out that firstly, "Agriculture" is an important content in this field, and "agricultural commercialization" and "rural space commodification" are hot topics. Secondly, Agricultural commercialization mostly describes the transformation process of African agriculture from self-sufficiency to marketization. Input of resource factors such as agricultural products, land, labor, market organization and capital affect output efficiency, while government power is rarely mentioned. Agricultural commercialization is an effective tool for achieving food security and poverty reduction. Thirdly, multi-type rural space commodification emphasizes rural consumption economy, cultural landscape, and other non-material innovative resources, which together with traditional rural resources constitute the "set" of tourism commodities. The influx of capital and government power are key drivers. Space commodification is an effective economic means for western rural revival. Fourthly, from productivism to spatial production theory, it depicts the process of rural change in western developed countries, reflecting the strategic change of rural core resources and the spatial distribution law of resource combination mode under different social stages and productivity levels. Finally, it is believed that the commodification of rural resources promotes the reorganization of local resources, which is the only way for rural revitalization. To promote the commodification of rural resources according to local conditions, it is necessary to fully consider the local economic level and the urban and rural location of the countryside, that is, to develop resources guided by market demand. At the same time, we must give full play to the wisdom functions of the government, especially the grass-roots governments. [ABSTRACT FROM AUTHOR]

Aflatoxin B1 is one of the most common fungal toxins in agricultural by-products, due to mutagenic, teratogenic, immunosuppressive, and carcinogenic effects. It is very necessary to develop reliable detection of aflatoxin B1 in agricultural by-products, in order to reduce the harm caused by aflatoxin B1. Traditional methods cannot fully meet the requirements of onsite and rapid detection in modern agriculture. Fortunately, electrochemical sensors have attracted much attention in recent years, due mainly to the simple preparation, easy portability, high sensitivity, and strong selectivity. According to the different recognition components, electrochemical sensors for aflatoxin B1 can be divided into aptamer-, immune response-, and molecular imprinting-based sensors. The recognition elements of these three sensors are antibodies, aptamers, and molecularly imprinted polymers, respectively. Various types of electrochemical sensors have also been developed for aflatoxin B1 using different perception strategies and nanomaterials, such as aptamer electrochemical sensors using competitive strategy, and aptamer electrochemical sensors using ratio strategy. This study aims to review the progress of electrochemical sensors for aflatoxin B1 over the past five years (2019-2023), thereby listing the representative examples, the sensing mechanisms, and signal generation strategies of sensors using different recognition elements. The performance of these sensors was compared to analyze the advantages and disadvantages of different recognition elements. The recommendations and development direction were discussed for the electrochemical sensors of aflatoxin B1 using different principles. The main conclusions were as follows: 1) The recognition components of AFB1 sensors mainly included adaptors, antibodies, and molecularly imprinted membranes at present. The preparation technology of recognition components and new recognition elements should be developed to further improve the performance of AFB1 sensors. 2) The high sensitivity of AFB1 sensors often required signal amplification using one or more nanocomposite materials. The performance of the AFB1 sensor depended mainly on nanomaterials. In addition, these types of sensors were still lacking in the structural stability and complex processing of highquality nanomaterials. Therefore, there is a high demand to develop novel nanomaterials with excellent performance. Preparation technology of nanomaterials can be expected to greatly improve the performance of AFB1 electrochemical sensors. 3) It is very necessary to combine different recognition components or perception strategies. The aptamers and antibodies were used in combination, together with the aptamers and MIP. More joint applications were explored in the future. 4) Most AFB1 sensors were used to detect a single toxin. However, multiple toxins often coexist in nature. Therefore, the sensors should be developed to simultaneously detect the multiple toxins in real matrices. This requirement can be fully met by integrating the electrodes with high-throughput technologies. 5) The AFB1 sensor is still in the laboratory research stage, and thus a lot of work needs to be done for the true commercial application. The preparation process of the AFB1 electrochemical sensor should be simplified with the sensitivity. The stability and generalization of the sensor should be improved to promote large-scale production and utilization. [ABSTRACT FROM AUTHOR]
