Abstract: The present disclosure provides use of a graphene oxide/butyl acrylate/silane composite emulsion as an anti-shrinkage agent of a cement-based material. In the present disclosure, active groups on an isobutyltriethoxysilane molecule reacts with hydroxyl groups on a surface of a mortar to form a layered hydrophobic structure, thereby slowing a water loss in the mortar of the cement-based material and avoiding cracking caused by drying shrinkage. Butyl acrylate can be dehydrated to form polymer fibers with a spatial network to fill pores of a cement paste, thereby limiting the shrinkage of the mortar. Graphene oxide has a relatively large specific surface area and oxygen-containing functional groups on a surface, which can provide growth sites for hydration products, and promote the hydration products to form a regular and dense structure in the form of a template, thus ensuring a strength of the cement-based material.

Abstract: Provided is the use of a silane composite emulsion as an anti-cracking enhancer in a cement-based material. In the present disclosure, active groups on an isobutyltriethoxysilane molecule react with hydroxyl groups on a surface of a mortar to form a layered hydrophobic structure, slowing down a water loss inside the mortar of a cement-based material. The dehydration of butyl acrylate forms a network structure, which fills pores of the cement-based material, inhibits shrinkage of the cement-based material, and reduces the cracking caused by the shrinkage. Tetraethoxysilane can undergo hydrolysis at a room temperature to generate nano-silica with a large number of hydroxyl groups on a surface; and the nano-silica can undergo secondary hydration with calcium hydroxide in the cement to form a secondary hydration product C—S—H gel, thereby filling most of voids to make a structure of the cement hydration product denser, to increase a strength of the mortar.

Abstract: The disclosure discloses construction of recombinant Saccharomyces cerevisiae for synthesizing carminic acid and application thereof and belongs to the technical field of genetic engineering and bioengineering. The disclosure obtains recombinant S. cerevisiae CA-B2 capable of synthesizing carminic acid by heterologously expressing cyclase Zhul, aromatase ZhuJ, OKS of Octaketide synthase 1, C-glucosyltransferase UGT2, monooxygenase aptC and 4?-phosphopantetheinyl transferase npgA in S. cerevisiae. The recombinant S. cerevisiae can be used for synthesizing carminic acid by taking self-synthesized acetyl-CoA and malonyl-CoA as a precursor. On this basis, OKS, cyclase, aromatase, C-glucosyltransferase and monooxygenase relevant to carminic acid are integrated to a high copy site, which can remarkably improve the yield of carminic acid. The yield of carminic acid can be increased to 2664.6 ?g/L by optimizing fermentation conditions, and the fermentation time is shortened significantly.

Abstract: A method for predicting an air quality index (AQI) based on a fusion model proposes a differential fusion seasonal prediction model (DF-SPM) based on a random forest (RF) model and a convolutional neural network (CNN)-long short-term memory (LSTM)-attention (CLA) model. This method uses the optimal threshold interval (OTI) search algorithm to search and learn the OTI of four seasons during the prediction process, and obtains the final prediction results according to the predicted values of RF model and CLA model. The fusion model combines the prediction advantages of two independent models, and fully considers the seasonal and periodic characteristics of AQI, so as to accurately search OTI in different time periods with the seasonal scale, so as to achieve higher prediction accuracy. The OTI strategy of fusion model is superior to the single threshold strategy, which can extract the historical fluctuation characteristics of AQI and achieve higher prediction accuracy.
