The emittances of the electron beams at the MAX-laboratory accelerator system have been studied. Apart from the build-up of the diagnostic tools for precise determination of the beam spatial profiles, the objectives have been: a) to verify the accelerator design emittances at low currents and to try to determine the emittances also at high currents; b) to investigate possibilities to manipulate th
Electrochemical synthesis of ammonia through the nitrogen reduction reaction (NRR) has the possibility to revolutionize our production of ammonia and to save our planet from both emissions and large energy consumption. In this study, a perovskite structured lanthanum chromite catalyst (LaCrO3) is synthesized, characterized as well as electrochemically evaluated for NRR. The highest ammonia yield i
Global warming increasingly challenges thermoregulation in endothermic animals, particularly in hot and dry environments where low water availability and high temperature increase the risk of hyperthermia. In birds, un-feathered body parts such as the head and bill work as ‘thermal windows’, because heat flux is higher compared to more insulated body regions. We studied how such structures were us
Solar-driven reduction of water to produce hydrogen is one of the most promising ways to develop sustainable cleanenergy for the future. The challenge in photocatalytic hydrogen evolution research is to design inexpensive catalystsand construct efficient hydrogen production systems. In this thesis, different photocatalytic hydrogen productionsystems consisting of catalysts, photosensitizers and sa
Alkaline electrochemical energy conversion devices generally require anion exchange membranes (AEMs) which combine limited water uptake and swelling with high hydroxide conductivity and high resistance against attack by the ubiquitous hydroxide ions. In this context, zwitterionic AEMs may offer distinct possibilities to tune AEM properties in relation to purely cationic AEMs. Here, we report on th
Bhutan is the world’s most mountainous country which comes with some logistical difficulties. Due to slow transportation times and lackluster food preservation are the post-harvest losses high which especially affects the rural parts of Bhutan negatively. Solar Food: Reducing post-harvest losses through improved solar drying, is a project set out to design a low-cost solar powered food dryer to im
Mixtures of powders of platinum with nickel or cobalt to obtain Ni0.75Pt0.25 or Co0.75Pt0.25 were mechanical alloyed by high energy ball milling. The results of crystal structure, morphology and electrocatalytic performance are presented for mechanically activated powders after 3 and 9 h of ball milling. Total solid solutions of Ni and Co with platinum were analyzed by X-ray diffraction after 3 h
Recent developments in European energy policy reveal an increasing interest in implementing the so-called ‘Tradable White Certificate’ (TWC) schemes to improve energy efficiency. Based on three evaluation criteria (cost-effectiveness, environmental effectiveness and distributional equity) this paper analyses the implications of implementing a European-wide TWC scheme targeting the household and co
Solid Waste Management RECOMMENDATIONS FOR KISUMU, KENYA Mistra Urban Futures Policy Brief 2019:1 Kisumu City generates approximately 400 tonnes of solid waste per day, 20%- 25% of which is collected to the open dump site. Of the total municipal solid waste that is collected, 65% is organic and another 27% is recyclable (County of Kisumu, 2015). The collection and handling of municipal solid waste

A novel insertion device for electron storage rings called the MAX-Wiggler has been constructed at MAX-lab. The MAX-Wiggler is a cold bore superconducting wiggler magnet with 47 3.5-T poles and. a period length of 61 mm aimed for the production of X-rays at the 1.5-GeV electron storage ring MAX-II at MAX-lab. The MAX-Wiggler consists of 98 racetrack coils connected in series in the superconducting
Three-dimensional direct numerical simulation with detailed chemical kinetics of lean premixed CH4/air and H-2/air flames at high Karlovitz numbers (Ka similar to 1800) is carried out. It is found that the high intensity turbulence along with differential diffusion result in a much more rapid transport of H radicals from the reaction zone to the low temperature unburned mixtures (similar to 500 K)
An experiment for salinity-gradient solar pond has been constructed and operated at the Dead Sea area over a period of 3 months. The pond has a volume of 5m3 with dimensions of (L, H, W) as 2.0m, 2.0m and 1,25m respectively. The two parameters temperature and salinity concentration profiles were evaluated through the measurements of the solar pond with respect to time. The experimental result show
Redox active cysteine residues including βCys93 are part of hemoglobin's “oxidation hotspot”. Irreversible oxidation of βCys93 ultimately leads to the collapse of the hemoglobin structure and release of heme. Human fetal hemoglobin (HbF), similarly to the adult hemoglobin (HbA), carries redox active γCys93 in the vicinity of the heme pocket. Site-directed mutagenesis has been used in this study to
A small-scale experiment for salinity-gradient solar pond has been constructed and operated at the Dead Sea area over a period of 3 months. The pond has a volume of 5m3 with dimensions of (L, H, W) as 2.0, 2.0 and 1,25 meter respectively. The two parameters temperature and salinity concentration profiles were evaluated through the measurements of the solar pond with respect to time. The experiment
