A singlemode optical fiber designed to reduce chromatic dispersion. The fiber core is fabricated in several layers with different refractive indices running in parallel throughout its length.

Proper use of dispersion agents in dispersions of organic nanoparticles can lead to improved dissolution and, thus, to improved bioavailability. It can even prevent crystallization of nanomaterials, ...

The total quantity of metal available for the reaction needs to be measured to characterize a catalyst sample. The available metal is measured in terms of a percentage of the total number of surface ...
