Graded index single crystal (GRISC) active waveguide in glass
TechnologyThe invention introduces a method for fabricating ferroelectric crystallines for use as low loss optical waveguides with additional active functionality compared to amorphous/glass waveguides.It provides low losses by confining the light signal tightly in the crystal core, away from the rough crystal-glassinterface that is often responsible...

Taming Antibiotics
Technology Amphotericin B (AmpB) is a potent antifungal drug but is also highly toxic to mammals. The specificity of its cell killing depends, significantly, on its monomer vs. the aggregate state. Specifically, AmpB aggregates tend to rupture membranes indiscriminately, like detergents, while the corresponding monomers sequester ergosterol (a sterol...

New Reagents for C4F8 Transfer that Eliminates the Use of Hazardous C2F4
SUMMARY Lehigh University has developed new (perfluoroalkyl)metallacyclic zinc reagents that could be used in applications to transfer sequential difluoromethylene groups to organic, inorganic, and organometallic substrates. The accompanying methods to prepare the new zinc reagents have also been developed by the university. Known synthetic routes...
