(author), Langeveld, J.G. (author)Illicit connections of wastewater to stormwater systems are the main drawback of separate sewer systems, as they lead to a direct discharge of untreated wastewater to the aquatic environment. Consequently, several inspection methods have been developed for detecting illicit connections. This study simultaneously applied several low- and high...journal article 2023

Tuluk, A. (author), Brouwer, J.C. (author), van der Zwaag, S. (author)BiFeO <sub>3</sub> is a multiferroic material with a perovskite structure that has a lot of potential for use in sensors and transducers. However, obtaining pure single-phase BiFeO <sub>3</sub> ceramic with a low electrical conductivity via solid-state reactions remains a problem that limits its application. In this work, the suppression of...journal article 2022

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
