Patterned Screen‐Printing Process for Substrate‐Free and Scalable Hyaluronic Acid Microneedle Arrays
Advanced Materials Technologies, EarlyView.A substrate‐free microneedle array comprising a hybrid hyaluronic acid ink was fabricated via a scalable screen‐printing process for flexible transdermal drug delivery. Defect‐free mold filling was achieved using a vacuum‐assisted jig and a delayed drying system, and the use of this versatile platform for multi‐drug patterning and ex vivo skin ...

Low-velocity cosmic strings in accelerating universe
, 2011 The standard cosmological model supposes that the dominant matter component changes in the course of the evolution of the universe. We study the homogeneous and isotropic universe with non-zero cosmological constant in the epoch when the dominant matter component has a form of a gas of low-velocity cosmic strings.

Advanced Robotics Research, EarlyView.This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

Effective potential for revolving D-branes
Journal of High Energy Physics, 2019 We quantize an open string stretched between D0-branes revolving around each other. The worldsheet theory is analyzed in a rotating coordinate system in which the worldsheet fields obey simple boundary conditions, but instead the worldsheet Lagrangian ...

Miniaturized Magnetic Tip Design for Endoluminal Vine Robot Navigation
Advanced Robotics Research, EarlyView.A magnetic tip mount is designed for a miniaturized 7 mm soft‐growing vine robot to enable wireless magnetic steering and onboard imaging, while preserving a 3 mm working channel. The internal–external ring magnets design balances magnetic attachment with low eversion pressure. Experiments demonstrate ±90° steering, 34 mm bending radius, and successful
