1. Fluorescence as a biological feedback signal for energy optimising spectra for greenhouse LED-illumination
Sammanfattning : The introduction of LED-lighting for greenhouses has enabled new ways of controlling the light, both spectrum and intensity, to save energy and increase crop production. We have investigated a new method of automatically tuning the spectrum based on biological feedback. LÄS MER
Sammanfattning : As part of a research project aiming to develop and evaluate a hydroponic system for wastewater treatment in Sweden, extended nutrient removal by microalgae was tested. The hydroponic/microalgal wastewater treatment system was built in a greenhouse in order to improve growth conditions for plants and algae. LÄS MER
3. Advanced silicon photoelectrodes for water splitting devices : design, preparation and functional characterization by photo-electrochemistry and high-energy X-ray spectroscopy
Sammanfattning : For the last century, mankind has been hugely dependent on fossil fuels to meet its energy needs. Harnessing energy from fossil fuels led to the emission of greenhouse gases. Greenhouse gases such as CO2 are a major contributor to global warming. LÄS MER
