Biodegradable bio composites with potential applications in medical implants were prepared starch content by situ polymerization technique using polyurethane prepolymers. (PU) and acrylamide (AAM) monomers. The structure properties of evaluated. FT-IR spectroscopy showed bonding between N=C=O functional group terminated polyurethanes confirmed improved compatibility prepolymers, AAM, composites...

Successful regeneration of biological tissues in vitro requires the utilization of three-dimensional (3D) scaffolds that provide a near natural microenvironment for progenitor cells to grow, interact, replicate, and differentiate to form target tissues. In this work, a rapid aqueous photo-polymerization route was developed toward the fabrication of a variety of polymer hydrogel 3D inverted coll...

In situ photopolymerized polyacrylamide (PAAm) gel plugs are used as hydrodynamic flow control elements in a multidimensional microfluidic system combining IEF and parallel SDS gel electrophoresis for protein separations. The PAAm gel plugs offer a simple method to reduce undesirable bulk flow and limit reagent/sample crosstalk without placing unwanted constraints on the selection of separation...

This study reports on an intelligent composite hydrogel with both pH-dependent drug release in a cancer environment and heat generation based on NIR laser exposure, for the combined application of photothermal therapy (PTT) and multidrug chemotherapy. For the first time in the literature, Dopamine nanoparticle (DP) was incorporated as a highly effective photothermal agent as well as anticancer ...

A year ago, we published a special issue of The Knowledge Engineering Review entitled \ Perspectives on Recent Intelligent Agents Research as Viewed through Two Conferences". Our intention was to provide a snapshot of current research on intelligent agents|an area which continues to grow apace|by looking at the work presented at the 1997 instantiations of two of the major events in the Agent ca...

In this study, polyacrylamide/alginate (PAAm/Alg) based hydrogels have been synthesized and investigated. The four different produced contained concentrations of single- or double- network polymer: 15 wt.% single-network (SN-15), 30 (SN-30), double-network (DN-15), (DN-30). tribological performance these was investigated by using a custom pin-on-disc tribometer in phosphate buffered saline (PBS...

Differentiation of embryoid bodies (EBs) into particular cell lineages has been extensively studied. There is an increasing interest in the effect of soft hydrogel scaffolds on the behavior of EBs, such as the initial adhesion, dynamic morphology change, and differentiation. In this study, without adding any other bioactive factors in the serum-containing medium, dynamic behaviors of mouse EBs ...

The Point Ahead Angle Mechanism (PAAM) for ESA’s Laser Interferometer Space Antenna (LISA) mission will compensate the out-of-plane point-ahead angle between three satellites flying 5 million kilometres apart. The PAAM consists of a mirror supported by flexures allowing the mirror to rotate with a maximum stroke of ±1 mrad. The mirror is actuated in 0.14 μrad steps by two redundant linear Piezo...
