Effect of recycling on the time- and temperature-dependent mechanical properties of PP/MWCNT composite liner materials by Attila Bata, Péter Gerse, Krisztián Kun, Emese Slezák, Ferenc Ronkay

“…In this study twin-screw extrusion was used to prepare the nanocomposites and their recyclates with 0.3, 0.5, and 1 w/w% MWCNT content, followed by injection molding to produce test specimens. Tensile and dynamic mechanical analysis (DMA) tests revealed that Young's and storage modulus of the recyclates increased, while elongation at break decreased compared to the base material due to the mechanical properties and stiffness of MWCNT. …”

Distinctive dust weather intensities in North China resulted from two types of atmospheric circulation anomalies by Q. Huo, Q. Huo, Z. Yin, Z. Yin, Z. Yin, X. Ma, X. Ma, H. Wang, H. Wang, H. Wang

“…The three-dimensional structure of atmospheric circulation anomalies and related dynamic mechanisms of the two types were concluded. To comprehensively forecast the two types of dust weather, a common predictor was constructed based on the 500 hPa cyclonic anomaly and anticyclonic anomaly circulation systems. …”

Optimization of Key Parameters for Coal Seam L-CO₂ Phase Transition Blasting Based on Response Surface Methodology by Xuanping Gong, Xiaoyu Cheng, Cheng Cheng, Quangui Li, Jizhao Xu, Yu Wang

“…First, three commonly used L-CO₂ blasting tubes with the overpressure of 150 MPa, 210 MPa, and 270 MPa were selected, and the corresponding material parameters and state equations were established. A dynamic mechanical constitutive model for a typical low-permeability, high-gas coal seam was then developed. …”
