Section snippets Exploring the potential of cellobiose lipids as sustainable biosurfactants There is interest from industry and society in biotechnology research to investigate environmentally friendly and sustainable biomolecules (see Glossary) to circumvent or replace synthetic chemical compounds from nonrenewable, petroleum-based sources, and move towards a more sustainable bioeconomy [1]. Microbial biosurfactants are excellent candidates to achieve this goal.

We experimentally investigate the buoyant miscible injection of a heavy viscoplastic fluid with moderate yield stresses into a lighter Newtonian fluid, via an eccentric inner pipe inside an inclined closed-end outer pipe. To capture the flow dynamics, we employ nonintrusive methods, including camera imaging and ultrasound Doppler velocimetry.

Children gaining access to unsafely secured firearms is a serious concern. Unintentional injury, including from firearms, is the leading cause of death in children.
