Rossing, Lars (author), Scharff, R.B.N. (author), Chömpff, Bryan (author), Wang, C.C. (author), Doubrovski, E.L. (author)Silicones have desirable properties such as skin-safety, high temperature-resistance, and flexibility. Many applications require the presence of a hard body connected to the silicone. Traditionally, it has been difficult to create strong bonding between silicones and hard materials. In this study, a technique is presented to control the...journal article 2020

Xu, Y. (author), Šavija, B. (author)Conventionally, the properties of cementitious materials are tailored by a simple but efficient method: mixture proportion design. For a given cementitious mixture, the chemical and physical properties of cementitious materials have already been determined. Consequently, the mechanical performance of the hardened cementitious material is...journal article 2021
