The work is to unravel the wave transmission mechanism through modeling the water-filled polycarbonate shell subjected to blast loading. The shock wave propagation inside a shock tube and the interaction between the shock wave and the surrogate head were captured using the arbitrary Euler-Lagrangian coupling method. Results demonstrated a complex fluid field around the head. Pressure history profiles at anterior and posterior sites of the brain simulant exhibited the typical coup and countercoup pattern, which were attributed to the surface pressure wave (direct loading) and the structural wave in the skull simulant (indirect loading). This study could enhance our understanding on blast-induced traumatic brain injury, leading to novel injury mitigation strategies.

Microfluidic Technique

Calcium alginate microfibers with spindle-knots are fabricated by combining microfluidic technique with wet-spinning method. The structures of the knots can be conveniently regulated by changing the two-phase flow rate ratio and the micropipette diameter.

Toxic Food

Food is often wasted due to real or perceived concerns about preservation and shelf life. Thus, precise, accurate and consumer-friendly methods of indicating whether food is safe for consumers are drawing great interest. The colorimetric sensing of biogenic amines released as food degrades is a potential way of determining the quality of the food. Herein, we report the use of genipin, a naturally occurring iridoid, as a dual colorimetric sensor for both oxygen and biogenic amines. Immobilization of genipin in edible calcium alginate beads demonstrates that it is a capable sensor for amine vapors and can be immobilized in a non-toxic, food-friendly matrix.
