    摘要： An oxadiazole dye for use as an organic photosensitizer. The oxadiazole dye comprising donor-π-spacer-acceptor type portions in which at least one of an oxadiazole isomer acts as a π-conjugated bridge (spacer), a biphenyl unit acts as an electron-donating unit, a carboxyl group act as an electron acceptor group, and a cyano group acts as an anchor group. An optional thiophene group acts as part of the π-conjugated bridge (spacer). The dye for use as organic photosensitizers in a dye-sensitized solar cell and in photodynamic therapies. Computational DFT and time dependent DFT (TD-DFT) modeling techniques showing Light Harvesting Efficiency (LHE), Free Energy for Electron Injection (ΔGinject), Excitation Energies, and Frontier Molecular Orbitals (FMOs) indicate that the series of dye comprise a more negative ΔGinject and a higher LHE value; resulting in a higher incident photon to current efficiency (IPCE).

    摘要： The metal organic framework adsorbent for solar adsorption refrigeration is a nanocomposite made from a metal organic framework matrix having carbon nanotubes incorporated therein. Preferably, the metal organic framework is composed of MIL-100(Fe), and the carbon nanotubes are functionalized with carboxyl (COOH) groups. In order to prepare the metal organic framework adsorbent, carbon nanotubes functionalized with carboxyl (COOH) groups are first added to an aqueous solution of a precursor salt, such as ferric trinitrate nonahydrate (Fe(NO3)3.9H2O), to form a first mixture. The first mixture is then sonicated and a 1,3,5 benzenetricarboxylic acid ligand is added thereto to form a second mixture. The second mixture is then sonicated and heated, and the metal organic framework nanocomposite is separated therefrom, preferably as a powder.
