Study on the evolution law of rock microstructure under loading and unloading water pressure Mater. Lett. (IF 3.0) Pub Date : 2024-04-08 Weitao Liu, Yuying Ren, Xiangxi Meng
The internal microstructure of rock under different pressures determines the stability of underground engineering. In this paper, the internal microstructure of rock under different loading and unloading water pressure is monitored by NMR in real time. The results show in the stage of loading and unloading water pressure, the variation law of water pressure is basically the same as that of porosity

Study of the control and influence of humidity on the mechanical and structural properties of geopolymer foam composites based on fly ash and wood flour Mater. Lett. (IF 3.0) Pub Date : 2024-04-08 Ancheng Weng, Xianglong Wan, Jinlang Hu, Shicheng Zhang, Shiping Han, Ziang Du, Dehan Chen, Yan Zhao
The geopolymer foam wood composites (GFWC), which are prepared from fly ash and wood flour, have high compressive strength and capacity for humidity control for potential applications in the construction industry. The compressive strength, apparent density and porosity of the composite were discussed by the relationship of properties and structure. The ability of the moisture absorption and desorption

Flexible ZrO2/ZrC/ZrB2 ceramic nanofiber mats by electrospinning with broadband electromagnetic absorption and high-temperature oxidation resistance Mater. Lett. (IF 3.0) Pub Date : 2024-04-08 Qian Wang, Lehua Qi, Yujun Jia, Hejun Li
Flexible ceramic electromagnetic (EM) absorbers with high thermal stability and broadband EM absorption are in high demand for applications under harsh conditions and EM absorption fields. In this study, we prepared flexible nanofiber mats containing ZrO, ZrC, and ZrB phases as EM absorbers by one-step electrospinning and high-temperature pyrolysis. The ceramic nanofiber mats, pyrolyzed at 1300 ℃ and
