For all the gel samples, the storage or elastic modulus (G') increased with increase in frequency of oscillation of the samples whilst the d... K Ofori-Kwakye,GP Martin - 《Journal of Science & Technology》 被引量: 1发表: 2005年 Study of the Viscoelastic Nature of Polymer Concrete ...
A viscous clear biocompatible gel, for example sodium hyaluronate, is used to inflate the anterior chamber to allow capsulorrhexis. Viscoelastic is also injected following lens removal into the anterior chamber and the capsular bag to allow safe IOL implantation. Viscoelastic materials possess a ...
A silicone gel is a reticulated polymer formed by polymerizing small multifunctional prepolymers: contrarily to other types of gels, there is no liquid phase trapped inside. Such cross-linked polymer networks exhibit scale invariance that yields power-law response of the form 17,30,31: Figure 2...
USA). Concentrations of acrylamide (10%) and bis-acrylamide (0.01%, w/v) were chosen to prepare a PAAm gel with approximately 1–2 kPa Young’s modulus, which is close to the eukaryotic cell stiffness. For AFM experiments, a total solution volume of ...
A gel is modeled as a two-phase medium that is composed of an equivalent polymer network and water molecules. The deformation of the network coincides with the macro-deformation of the gel (the affine hypothesis). The network consists of two types of chains: permanent (both of their ends ar...

Stem cells, particularly human iPSCs, constitute a powerful tool for tissue engineering, notably through spheroid and organoid models. While the sensitivity of stem cells to the viscoelastic properties of their direct microenvironment is well-described, stem cell differentiation still relies on biochemical...
