Endosulfan (6,7,8,9,10,10-Hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-methano-2,4,3-benzodioxathiepine-3-oxide) is an off-patent insecticide used in agricultural farms. Its usage as a pesticide has become highly controversial over the last few decades. This is due to its reported hazardous nature to health and side effects like growth retardation, hydrocephalus, and undesired changes in the male and female hormones leading to complications in sexual maturity. Endosulfan is the main culprit among all pesticide poisoning incidents around the world. Though the usage of this dreaded pesticide is banned by most countries, the high stability of this molecule to withstand degradation for a long period poses a threat to mankind even today. So, it has become highly essential to detect the presence of this poisonous pesticide in the drinking water and milk around these places. It is also advisable to check the presence of this toxic material in the blood of the population living in and around these places so that an early and appropriate management strategy can be adopted. With this aim, we have developed a sensor for endosulfan that displayed high selectivity and sensitivity among all other common analytes in water and biological samples, with a wide linear concentration range (2 fM to 2 mM), a low detection limit (2 fM), and rapid response. A citrate-functionalized cadmium-selenium quantum dot was used for this purpose, which showed a concentration-dependent fluorescence enhancement, enabling easy and sensitive sensing. This sensor was utilized to detect endosulfan in different sources of water, human blood serum, and milk samples with good recoveries. It is also noted that the quantum dot forms a stable complex with endosulfan and is easy to separate from the contaminated source, paving the way for purifying the contaminated water. More detailed tests and validation of the sensor are needed to confirm these observations.

The concept of output-oriented education has been introduced for many years in our country and has been widely used in the process of personnel training in Chinese universities. This paper discusses how the concept of Outcome Based Education can be fully integrated into the process of developing talents in an interdisciplinary and collaborative manner in the context of new engineering. We have made useful explorations in various aspects from curriculum system integration, online teaching resources construction, studio-style course organization mode, rich teaching project library to school-enterprise cooperation project practice, etc., which have improved students' learning effect.

In the highly developed process of "Internet plus", foreign trade transformation and upgrading, cross-border new retail rapid development has become the trend of the times, cross-border e-commerce new retail digitalization, and improving operational efficiency brings new opportunities. Reshaping the structure of new retail formats, the integration of cross-border e-commerce and new retail formats is an inevitable trend. Smart upgrading and digital transformation are important measures to achieve leapfrog development. The format structure presents business models such as "smart retail, digital cross-border e-commerce, new cross-border e-commerce, new retail, and new retail logistics". The main research objective of this project is to explore and research the new retail scenarios of digital applications in cross-border e-commerce. Based on the current development trend of digital cross-border e-commerce and new retail upgrading, as well as the economic characteristics of the Wuyi area in Jiangmen City, this project aims to use the smart new retail scenario of digital cross-border e-commerce as the foothold, with a focus on upgrading and transforming the product flow chain with the "application scenario" as the central point, form a closed-loop loop of free circulation of products, new retail logistics, cross-border e-commerce, new retail, new sales experience scenarios, and consumers.
