  1. 1. ZnO and CuO Nanostructures: Low Temperature Growth, Characterization, their Optoelectronic and Sensing Applications

    Författare :Gul Amin; Magnus Willander; Omer Nour; Anastasios Travlos; Linköpings universitet; []
    Nyckelord :Zinc oxide; Copper II oxide; Nanostructures; Hydrothermal growth; Light emitting diodes.;

    Sammanfattning : One dimensional (1-D), zinc oxide (ZnO) and copper (II) oxide (CuO), nanostructures have great potential for applications in the fields of optoelectronic and sensor devices. Research on nanostructures is a fascinating field that has evolved during the last few years especially after the utilization of the hydrothermal growth method. LÄS MER

    Författare :Niklas Sköld; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nano; Nanowire; photoluminescence; epitaxy; quantum dot;

    Sammanfattning : This thesis describes growth, processing, characterization and photoluminescence (PL) spectroscopy of nanowire heterostructures. The nanowires were made of III-V semiconductor materials and were produced by Au-particle assisted growth. LÄS MER

  4. 3. Cellulose-based Conducting 3D and 2D Composites for Applications in Plant Science and Responsive Systems

    Författare :Vasileios Oikonomou; Eleni Stavrinidou; Magnus Berggren; Anna Herland; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymers; cellulose; conjugated polymers; volume changes; plant growth substrates;

    Sammanfattning : Polymers (Greek: poly=many, meros=part) are large molecules made up of many small parts (monomers) in a repetitive way, as a term was introduced for the first time (1833) by the Swedish chemist, Jöns Jakob Berzelius. By the combination of different monomers, the resulting polymer can exhibit various properties, such as biodegradability, photosensitivity and electrical conductivity. LÄS MER

  5. 4. Chlorophyll fluorescence as a biological feedback signal -for optimized plant growth conditions and stress diagnosis

    Författare :Linnéa Ahlman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cucumber; indoor farming; abiotic stress; Fluorescence gain; ESC; biotic stress; basil; dynamics; strawberries; light spectrum; greenhouse lighting control; lettuce; powdery mildew Podosphaera aphanis; Pythium ultimum; LED; classification; lemon balm;

    Sammanfattning : The use of light emitting diodes (LEDs) instead of traditional high pressure sodium lamps, in greenhouses and indoor growing facilities, enables tuning and optimization of both light intensity and light spectrum. This opens for an energy saving potential not possible otherwise. LÄS MER
