  2. 16. Development of Novel Hydroporphyrins for Light Harvesting and Sensitising NIR Lanthanide Luminescence

    Author : Ruisheng Xiong; Eszter Borbas; Christian Brückner; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chlorin; hydroporphyrin; chlorophyll analogues; light harvesting; lanthanide luminescence; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : Chlorins, as the core structures of chlorophylls, have been extensively studied for harvesting solar energy, fluorescent imaging and photodynamic therapy against cancer. This thesis is concerned with design and synthesis of novel chlorins as antennae for harvesting light and sensitising near infrared lanthanide luminescence. READ MORE

  4. 17. Advanced Metal Oxide Semiconductors for Solar Energy Harvesting and Solar Fuel Production

    Author : Pedram Ghamgosar; Alberto Vomiero; Nils Almqvist; Omer Nour; Luleå tekniska universitet; []

  7. 20. Rain water harvesting and supplemental irrigation at Sinjar district in northwest Iraq

    Author : Saleh Zakaria; Rafid Alkhaddar; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Rainwater harvesting is one of the methods that can ensure availability of water for winter crop in Iraq. Using this technique the excess rainwater (runoff) is stored in reservoirs of dams of different sizes. The water from these reservoirs can be used later when required to satisfy the crops requirements. READ MORE
