A novel bipolar pulse electrochemical polishing approach for ultra-precision conformal polishing of microlens arrays by Jun Yang, Yongjie Zhang, Jingtian Ye, Yuxi Xiao, Hui Deng, Xinquan Zhang

“…Ultra-precision polishing technology is an effective method for removing mechanical defects, such as knife lines and burrs, from the surfaces of optical microstructure components. The contact polishing method does not satisfy the requirements for conformal polishing of microstructures, as the polishing tool may exceed the size of the microstructure, and excessive mechanical force can easily damage the microstructure. …”

Effect of rice husk ash content and carbonization curing on lime-stabilized recycled aggregates: mechanical behavior and microscopic mechanism by Haocheng Lai, Kaihao Lin, Na Li, Junyi Qin, Yifang Song, Yiming Jiang, Wei Wang

“…The main findings are as follows: (1) Both RHA and carbonation treatment significantly improve the UCS of lime-stabilized recycled aggregates, with optimal RHA content and carbonation time identified as 6% and 12 h, respectively. (2) RHA and carbonation treatment do not alter the chemical composition of RLA but promote the formation of C–S–H gels and CaCO _3 . (3) The combination of RHA and carbonation treatment enhances the densification of C–S–H gels in RLA; however, excessive carbonation results in decalcification of the C–S–H gel, which reduces the calcium-to-silicon ratio of RLA. (4) Both RHA and carbonation treatment contribute to reducing porosity and improving microstructure of RLA. …”
