Hydrogels have a large number of potential applications in microelectromechanical technology as sensors and actuators. In this paper we try to understand the physics of dissolvable hydrogels and investigate the various parameters controlling the dissolution process. Hydrogels, crosslinked via disulfide bonds, when immersed in a solution containing the disulfide cleaving agent can break covalent...

In the present set of studies, the authors examine the idea that self-sacrificial leadership motivates follower prosocial behavior, particularly among followers with a prevention focus. Drawing on the self-sacrificial leadership literature and regulatory focus theory, the authors provide results from 4 studies (1 laboratory and 3 field studies) that support the research hypothesis. Specifically...

Porous alumina ceramics with different porosities were prepared via atmospheric pressure sintering using a sacrificial template method powder as the raw material and carbon fiber (CF) graphite pore-forming agents. The effects of contents ratios agents aspect CF on microstructure, mechanical properties, pore size, pore-size distribution porous samples investigated. In addition, surface fractal d...

In this work, we describe a simple 1-mask sacrificial layer process that allows us to prototype a tuneable capacitor. The process is specially optimized to procure a dual picks profile of the sacrificial layer. The geometry design and the influence of the structural material stress were considered through the finite element analysis. The FEM simulation with Ansys was used to study in detail pro...

Hydrogels can promote desirable cellular phenotype by mimicking tissue-like stiffness or serving as a gene delivery depot. However, nonviral gene delivery inside three-dimensional (3D) hydrogels remains a great challenge, and increasing hydrogel stiffness generally results in further decrease in gene delivery efficiency. Here we report a method to enhance nonviral gene delivery efficiency insid...
