Hydrogels are materials used in a variety of applications, ranging from tissue engineering to
drug delivery. The incorporation of nanoparticles to yield composite hydrogels has gained …

Topology plays a critical role in dictating the properties of many materials. In recent years,
with advances in synthetic and characterization techniques, substantial efforts have been …

Polymer gels have two types of concentration fluctuations; liquidlike and solidlike
fluctuations. The former are time‐dependent (thermal) fluctuations and the latter are time …

The small angle neutron scattering experiments were conducted on N‐isopropyl acrylamide
(NIPA) gels in D2O and on the corresponding NIPA solutions. The NIPA gels underwent a …

Many polymer networks and gels display nanostructural heterogeneity in the form of
spatially inhomogeneous crosslinking densities, along with additional topological defects …

The free-radical polymerization of acrylamide in aqueous clay dispersions and the structure
of the resulting polymer− clay nanocomposite hydrogels have been investigated by …

Polymer-network gels often display nano-to microstructural spatial inhomogeneity of their
polymer-segmental and crosslinking densities, especially if they are formed by uncontrolled …

The structure of Tetra-PEG gel, a new class of biocompatible, easy-made, and high-strength
hydrogel consisting of a four-arm polyethylene glycol (PEG) network, has been investigated …

A series of model networks consisting of polyethylene glycol (PEG), tetra-PEG gels, have
been prepared and their structure and dynamics have been investigated by small-angle …

Cystic fibrosis (CF) is characterized by the presence of a viscoelastic mucus layer in the
upper airways and bronchi. The underlying problem is a mutation in the gene encoding the …
