Article Abstract
A field experiment was conducted at the Key Field Station for Monitoring of Eco-Environment of Purple Soil of the Ministry of Agriculture of China at the farm of Southwest University in Chongqing. In the study, static chamber and gas chromatography methods were used to study the effects of plastic film mulching treatment on CO, CH, and NO emissions from rice-rapeseed rotation in situ for one year. A control experiment was also conducted without using the film. The CO, CH, and NO emission fluxes of the rotation showed obvious seasonal changes, and the seasonal variation patterns of these three greenhouse gases were similar under the two treatments. The CH emission of the rotation under the plastic film mulching treatment was (46.14±13.40) kg·hm, or 147.93% (<0.05), compared with (18.61±2.05) kg·hm for the control. However, the impact of plastic film mulching on CO and NO emissions was not significant. The annual CO emissions under the plastic film treatment and the control were (-47.54±2.11) t·hm and (-47.60±2.19) t·hm, respectively, and the annual emissions of NO were (18.94±4.74) kg·hm and (23.14±3.68) kg·hm, respectively. The rice-rapeseed rotation in the two experiments showed absorption and sinking of atmospheric greenhouse gases, although the difference was not significant. The global warming potential (GWP) values with the plastic film treatment and the control were -41.16 t·hm and -40.95 t·hm, respectively.

Polymers of intrinsic microporosity (PIMs) have received considerable attention for making high-performance membranes for carbon dioxide separation over the last two decades, owing to their highly permeable porous structures. However, challenges regarding its relatively low selectivity, physical aging, and plasticisation impede relevant industrial adoptions for gas separation. To address these issues, several strategies including chain modification, post-modification, blending with other polymers, and the addition of fillers, have been developed and explored.

Two plasticizers with distinct properties are carefully studied in this research for their suitability in creating biocomposite edible film products. The study uncovers films' physical, tensile, and biodegradability attributes, using snakehead gelatin and ĸ-carrageenan in different concentrations, with sorbitol or glycerol as plasticizers. The biomaterials of the edible film consist of snakehead gelatin () 2% (/); ĸ-carrageenan at concentrations of 1%, 1.

Alginate films were prepared from the brown seaweed Dictyota mertensii using glycerol as a plasticizer. The effects of extraction conditions-time, temperature, and NaCO concentration-on the optical, barrier, and mechanical properties of the films were investigated using a central composite design (CCD). ANOVA and F tests confirmed the models' statistical significance at p ≤ 0.

Plastic film mulching is a potentially water-saving cultivation strategy, while straw return coupled with nitrogen (N) fertilization can ensure sustainable soil productivity and increased soil organic matter (SOM) sequestration. Nevertheless, a comprehensive understanding of how soil quality and agronomic productivity respond to long-term N fertilization and straw incorporation practices under non-flooded conditions with plastic film mulching remains elusive. Herein, a 15-year field experiment with straw incorporation practices (straw return and no straw return) under various N fertilization rates (N0, N1, N2, N3, and N4: 0, 45, 90, 135, and 180 kg N ha, respectively) was conducted to explore their long-term effects.
