Increasing Lipid Nanoparticle mRNA Copy Number Improves Transfection Potency
Advanced Materials, EarlyView.As lipid nanoparticle (LNP) systems are the leading platform for in vivo nucleic acid delivery, improving transfection potency of these systems is of considerable interest. In this work, we explored a post‐mixing formulation method involving a two‐step buffer exchange that increased the number of mRNA copies within each LNP while reducing the number of

Influence of pulse poling on the piezoelectric property of Pb(Zr0.52,Ti0.48)O3 thin films
AIP Advances, 2014 We have investigated the influence of pulse poling on the piezoelectric property of Pb(Zr0.52,Ti0.48)O3 (PZT) thin films. 1.9-μm-thick PZT thin films were deposited by sol-gel method and fabricated into microelectromechanical systems (MEMS) based ...

Directional Confinement Governed Ion Transport for Efficient Actuation
Advanced Materials, EarlyView.Structural anisotropy provides an effective means to regulate ion transport in polymer electrolytes. Directionally aligned channels formed by freeze‐drying provide continuous pathways for ion migration, enhancing ion mobility and simultaneously improving the strain and blocking force of ionic actuators.

Habitat-Specific Design Strategies for Untethered Soft Robots. [PDF]
Adv Sci (Weinh)Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...
