Chen, Y. (author), Chaves Figueiredo, S. (author), Li, Z. (author), Chang, Z. (author), Jansen, K. (author), Copuroglu, Oguzhan (author), Schlangen, E. (author)In 3D concrete printing (3DCP), it is necessary to meet contradicting rheological requirements: high fluidity during pumping and extrusion, and high stability and viscosity at rest to build the layered structure. In this paper, the impact of the hydroxypropyl methylcellulose (HPMC)-based viscosity-modifying admixture (VMA) on the 3D printability...journal article 2020

(author), Chen, Yong (author), Zhao, Bo (author)Body Channel Communication (BCC) offers a low-loss signal transmission medium for ultra-low-power wearable devices on human body [1]. However, the effective communication range on human body is limited to less than 1m in the state-of-the-art BCC transceivers [2], where the signal loss at the interface of body surface and BCC receiver remains to...conference paper 2022
