The creep failure of rocks is related to its microstructure, external loading and time. A nonlinear yield model was introduced to describe the variation in the cohesion and friction angle with plastic strain and intergranular stress. The mechanical properties and creep characteristics of deep granite were obtained by indoor tests, and a variable radius particle clump model was constructed based on the particle flow method.

Replacing traditional plastic mulch with fully biodegradable mulch is an important research direction to solve the problem of "white pollution," but whether it can truly realize biodegradation is still the focus of many scholars. In this study, field and indoor experiments were carried out in Pingluo County, Ningxia Hui Autonomous Region, using poly(butyleneadipate-co-terephthalate) (PBAT) fully biodegradable mulch film and ordinary polyethylene (PE) mulch film, with no mulch film (CK) as the control. Macroscopic characteristics such as the degree of apparent cracking of the mulch film, loss of the mulch film area, and the rate of weight loss were observed, and the results were combined with the results of scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and thermogravimetry (TGR).

Corn stover, as an abundant agricultural residue, has not been well reutilized due to the lack of efficient utilization methods. Based on micro/nanoscale structure design of corn stover, we report an environmentally friendly strategy to prepare micro/nanostructured corn stover-based building blocks. Then, through the directed deformation assembly approach, a high value-added corn stover structural material (CSSM) that with higher strength and more excellent thermal stability than most widely used plastics and wood-plastic composites can be prepared.

This study investigated the effect of light on emission of various volatile and semi-volatile organic compounds (VOCs and SVOCs), from polyvinyl chloride (PVC) products using xenon lamp as a solar light simulator. The emission flux generally decreased over time, with the light-induced targeted ∑VOC flux being about 1.6-times higher than heat-induced flux during the initial 1-h exposure.

The existence of a large number of thermal bridges in the Lightweight Steel-Framed (LSF) building leads to its energy loss. The reduction of the heat transfer of thermal bridges is crucial for increasing the thermal performance of the building envelope. In this study, the infrared technology was first used to measure the temperature of LSF buildings, and clear thermal bridge junctions were determined.
