BACKGROUND Though the transplantation of in vitro expanded human corneal endothelial precursors in animal models of endothelial damage by injecting into the anterior chamber has been reported, the practical difficulties of accomplishing such procedure in human patients have been a hurdle to clinical translation. Here we report the successful transplantation of in vitro expanded human corneal pr...

In this study, the drying-induced microstructure evolution of compacted silt with different salinities is investigated using mercury intrusion porosimetry and environmental scanning electron microscope. The pore size distribution (PSD) specimens near optimum (w = 17%) exhibited bimodal characteristics. Upon drying 8%), PSD changed to a trimodal pattern appearance new nano-pore population. This ...

Polymer-clay nanocomposites are more popular in many industries and applications due to improved mechanical gas barrier properties over pure polymers classical polymer-based composites. The mechanism by which clay platelets, with thicknesses the nanometer range, as opposed hundred-nanometer range other two dimensions, introduce improvement can be attributed their high efficiency creating discon...

The fabrication of silk-based membranes that are stable, optically transparent and reusable is yet to be achieved. To address this bottleneck we have developed a method to produce transparent chromogenic silk patches that are optically responsive to pH. The patches were produced by blending regenerated silk fibroin (RSF), Laponite RD (nano clay) and the organic dyes neutral red and Thionine ace...
