Rapid removal of Cr(VI) from aqueous solution by novel sepiolite/Fe3O4/nZVI nanocomposite: Material characterizations, enhanced performance in Cr(VI) removal and mechanism

Authors: HOU Kai, HUANG Li, CHEN Wei, LI Xue-lian, HE Xi, LIU Ai-fang, DU Juan, ZHAO Yue-jie, YAO Shun, WEI Yu-han, FENG Guo-rui

The novel magnetic sepiolite/Fe3O4/zero-valent iron (nZVI) nanocomposite (nZVI@SepH-Mag) was prepared and used to achieve the removal of Cr(VI) in this work. The nZVI@SepH-Mag composites were characterized by XRD, FTIR, BET, SEM and TEM. The characterization results indicated that the structure of the composite consisted of small nanoscale nZVI and magnetite (Mag) particles uniformly anchoring on the surface of acid-activated sepiolite (SepH). Batch experiments were used to analyze the effects o

Authors: FANG Xiu-yang, WANG Zheng, GONG Jian-en, WANG Zhi-guo, CHEN Tai-li, NI Jing, CAI Zhen-bing

The effects of nanosecond laser shock peening without coating (LSPwC) and nanosecond stacked femtosecond laser shock peening compound strengthening (LSP-CS) on the surface integrity and fretting fatigue lifetime at 500 ℃ of GH4169 dovetail component were investigated. The results show that LSP treatment does not significantly lead to changes in the grain size of GH4169 alloy, but it introduces a large number of dislocations, resulting in the formation of a plastic deformation layer and residual

Effects of alloying elements M (Mn, Cr, Mo, Ni, Cu, and Si) on interface behavior of TiC(002)/Fe(011)

Authors: LI Jia-xin, HOU Guang-xin, JIA Peng, HU Li-hua, WANG Li-quan, WANG Xiang

Improving interfacial bonding and alloying design are effective strategies for enhancing mechanical properties of particle-reinforced steel matrix composites (SMCs). This study prepared SMCs with uniformly distributed TiCP in matrix using master alloying method. The TiC(002)/Fe(011) interface model was established based on the orientation relationship of (011)Fe//(002)TiC, and [100]Fe//[100]TiC. The effects of single and co-doping of alloying elements (Mn, Cr, Mo, Ni, Cu and Si) on the interface bonding behavior of TiC/Fe in composites were investigated in conjunction with first-principles. The results demonstrate that the interface between TiC and matrix is continuous and stable. Compared to the undoped TiC/Fe interface, single-doping Mn, Cr, and Mo can improve the stability of TiC/Fe interface and enhance tensile strength. Conversely, single-doping with Ni, Cu, and Si reduced the interface stability and marginally reduces tensile strength. Relative to the undoped and singly Ni-doped TiC/Fe interfaces, the co-doping Ni-Mo boosts binding energy and separation work at the TiC/Fe interface, which is conducive to the interface bonding between TiCP and matrix, and thus improves the mechanical properties of composites. Thus, in the alloying design of TiC particle-reinforced low-alloy SMCs, incorporating Mn, Cr, Mo, and Ni into matrix can enhance the overall mechanical properties of composites.

Effects of horizontal splitter plates on the vortex-induced vibration and aerostatic characteristics of twin separated parallel decks for a rail-cum-road bridge

Authors: HE Xu-hui, YANG Jia-feng, LIU Lu-lu, ZOU Yun-feng, HE Jing

Installing the splitter plates is a passive aerodynamic solution for eliminating vortex-induced vibration (VIV). However, the influences of splitter plates on the VIV and aerostatic performances are more complicated due to aerodynamic interference between highway and railway decks. To study the effects of splitter plates, wind tunnel experiments for measuring VIV and aerostatic forces of twin decks under two opposite flow directions were conducted, while the surrounding flow and wind pressure of

Cryogenic forging effects and mechanisms on surface coarse grain microstructure in H-shaped 7050 aluminum forgings

Authors: ZHAO Zi-han, YI You-ping, HU Jian-liang, HUANG Shi-quan, HE Hai-lin

This study investigates the differences in microstructural control between cryogenic forging combined with pre-deformation (PCF) and traditional thermal forging (TTF) for 7050 aluminum forgings intended for aerospace applications. The PCF process, utilizing cryogenic deformation, significantly refines the coarse grains at the surface of the forgings, resulting in a finer and more uniform microstructure, thereby effectively addressing the issue of surface coarse grains associated with traditional

Generation of axial chain rockbursts in deep tunnels with drilling and blasting methodology in locked-in stress zone

Authors: LI Hong-pu, HE Ben-guo, FENG Xia-ting, NIU Wen-jing, MA Tao

Axial chain rockbursts (ACRs) repeatedly occur in deep tunnels during drilling and blasting methodology (D&B) within locked-in stress zones, severely hindering construction progress. In extremely cases, ACRs can persist for 7−10 d and affect areas exceeding 20 m along tunnel axis. Through integrated geological investigations and microseismic (MS) monitoring, the geological characteristics, MS activity patterns, and formation mechanisms of ACRs were analyzed. In tectonically active regions, locked-in stress zones arise from interactions between multiple structural planes. Blasting dynamic disturbances during tunnel excavation in these zones trigger early slippage along structural planes and fractures in the surrounding rock, with MS events developing ahead of the working face. High-energy MS events dominate during the development and occurrence stages of ACRs, extending 20−30 m (3−4 tunnel diameters) ahead of the working face. Following the ACRs, low-energy MS events primarily occur behind the working face. Tensile fracturing is the predominant failure mode during ACRs. Shear and mixed fractures primarily occur within the ACRs zone during the intra-ACR phase. Monitoring MS event locations ahead of the working face provides a reliable approach for prewarning potential ACR-prone zones.
