Chen, Jing (author), Liu, X. (author), Zeng, Xiao Liang (author), Ye, Huai Yu (author), Zhang, Kouchi (author)Hexagonal boron nitride (BN) is often used as filler to improve the thermal conductivity of polymer matrix due to its high thermal conductivity. However, previously reported BN-based composites always have a high in-plane thermal conductivity, which is not beneficial for vertical heat dissipation. In addition, high BN content results in the...journal article 2022

Yang, Zhengxian (author), Shi, Peng (author), Zhang, Yong (author), Li, Z. (author)The influences of liquid-binder ratio and mixing sequence on the performance of superabsorbent polymer (SAP)-containing alkali-activated slag (AAS) mortar are investigated in this study. It is found that the SAP absorbs much less liquid in upper supernatant of AAS than in water. Mixing SAP with liquid first induces a larger absorption...journal article 2022

Feng, Zhen (author), Liu, Daoyin (author), Zhang, Wangle (author), Feng, Hao (author), van Ommen, J.R. (author)Fluidization of nanoparticle agglomerates is a promising technique to process nanoparticles. However, possible elutriation of small agglomerates may cause significant loss of bed material. To obtain the elutriation behavior under stable operation, in this study the elutriation fraction of silica nanoparticle agglomerates is measured in a...journal article 2022

Zhang, F. (author), Yang, Y. (author), Fennis, Sonja A.A.M. (author), Hendriks, M.A.N. (author)Acoustic emission (AE) signal parameters can be used to classify the source type in concrete structures. However, signal parameters are influenced by the wave propagation from the source to the receiver, leading to wrong source classification results, especially for monitoring large concrete structures. This paper experimentally evaluates the...journal article 2022

Zhang, J. (author), Aragon, A.M. (author)Stress analysis is an all-pervasive practice in engineering design. With displacement-based finite element analysis, directly-calculated stress fields are obtained in a post-processing step by computing the gradient of the displacement field—therefore less accurate. In enriched finite element analysis (EFEA), which provides unprecedented...journal article 2022
