Using unmanned aerial vehicles (drones) to improve access to blood in low‐ and middle‐income countries: Current challenges and opportunities

Vox Sanguinis, EarlyView.
Abstract Blood transfusion is life‐saving for patients in emergencies, but low‐ and middle‐income countries (LMICs) often face a severe shortage of banked blood. Establishing blood banks in rural areas presents substantial logistical and economic challenges for many LMICs.

Spheres, tears, and spears: Regulating the perimeter and circularity of millimeter‐sized alginate hydrogel beads

AIChE Journal, Volume 72, Issue 6, June 2026.
Abstract Generating hydrogel beads pertains to many engineering applications. We examined two alginate‐based fluids at three concentrations of alginate, cAG. We used the “Map of Misery” to determine which material property (viscosity, elasticity, and inertia) drives droplet formation. Next, we measured the perimeter and circularity of hydrogel beads as

FENCE: Flexible Electric Noise Reduction Endo‐Shield for the Suppression of Electromagnetic Interference in Low‐Field MRI

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
Electromagnetic interference (EMI) is a significant challenge for low‐field MRI. Traditional EMI mitigation approaches either limit portability or demand advanced hardware. We present FENCE (Flexible Electromagnetic Noise reduCtion Endo‐shield), a novel approach for EMI mitigation using flexible PCBs placed inside the RF coil.

Packaging of Macroscopic Material Payloads: Needs, Challenges, Concepts, and Future Directions

Advanced Engineering Materials, Volume 28, Issue 9, 6 May 2026.
This review introduces a unified framework that decomposes any macroscopic packaging system into the payload, packaging material, and packaging strategy and combines them into a conceptual packaging equation: packaging strategy = payload + packaging material.
