Abstract The transport of motile microorganisms is strongly influenced by fluid flows that are ubiquitous in biological environments. Here we demonstrate the impact inertia. We analyze dynamics a microswimmer pressure-driven Poiseuille flow, where inertia small but non-negligible. Using perturbation theory and reciprocal theorem, show addition to classical inertial lift passive particles, active nature generates ‘swimming lift’, which evaluate for neutral pusher/puller-type swimmers....
Steelmaking contributes 8% to the total CO 2 emissions globally, primarily due coal-based iron ore reduction. Clean hydrogen-based ironmaking has variable performance because dominant gas–solid reduction mechanism is set by defects and pores inside mm- nm-sized oxide particles that change significantly as reaction progresses. While these governing dynamics are essential establish continuous flow of its ores through reactors, direct link between agglomeration chemistry still contested missing...
Abnormalities in biophysical properties of blood are often strong indicators life threatening infections. However, there is no existing device that integrates the sensing hematocrit (or equivalently, packed cell volume), viscosity, and erythrocyte sedimentation rate (ESR) a unified paradigm for point-of-care diagnostics. In an effort to develop rapid, integrated, accurate, portable, inexpensive platform diagnose corresponding pathophysical parameters, we simple portable spinning disk capable...
About 1.9 gigatonnes of steel is produced every year emitting 7\% (2.7 gigatonnes) global CO$_2$ in the process. More than 50\% emissions come from a single step steelmaking, known as ironmaking. Hydrogen based direct reduction (HyDR) iron oxide to has emerged an free ironmaking alternative. However multi-scale phenomena ranging nanometers meters inside HyDR reactors exhibit detrimental microstructure evolution which resists gaseous transport H$_2$/H$_2$O, slows reaction rates and disrupts...

We analyze the dynamics of a microswimmer in pressure-driven Poiseuille flow, where fluid inertia is small but non-negligible. Using perturbation theory and reciprocal theorem, we show that addition to classical inertial lift passive particles, active nature generates `swimming lift', which evaluate for neutral pusher/puller-type swimmers. Accounting engenders rich spectrum novel complex including bistable states, tumbling coexists with stable centerline swimming or swinging. The sensitive...
