Ternary Rare-Earth-Metal Nickel Indides RENiIn (RE = Gd, Tb, Dy) with YbCuMg-Type Structure.

The ternary rare-earth-metal nickel indides RENiIn (RE = Gd, Tb, Dy) were prepared by arc-melting mixtures of the elements followed by annealing at 870 K. They adopt the YbCuMg-type structure (space group 6/, Pearson symbol 68, = 2), as determined by laboratory and synchrotron powder diffraction methods for RE = Gd ( = 9.6435(10) Å, = 22.

Photobleaching kinetics of optically trapped multilamellar vesicles containing verteporfin using two-photon excitation section sign.

Two-photon excitation photodynamic therapy (TPE-PDT) is being developed as an improved treatment for retinal diseases. TPE-PDT has advantages over one-photon PDT, including lower collateral damage to healthy tissue and more precise delivery of PDT. As with one-photon PDT, there can be local photochemical depletion of oxygen during TPE-PDT.
