Proton-transfer dynamics plays a critical role in many biochemical processes, such as proton pumping across membranes and enzyme catalysis. The large majority of enzymes utilize acid-base catalysis and proton-transfer mechanisms, where the rates of proton transfer can be rate limiting for the overall reaction. However, measurement of proton-exchange kinetics for individual side-chain carboxyl grou
Alberta’s energy sector provides a reliable supply of energy and contributes to the economy of Alberta. In addition to these positive aspects, there are concerns about the environmental, economic and social performance of the energy sector. The purpose of this thesis is to critically examine the production side of Alberta’s energy sector and offer constructive ideas about how the sector could be b
To satisfy the great need for (opto-)electronic devices to become smaller and more efficient in energy and price, research is done on semiconducting III-V nanowires (NWs). Electrical devices using NWs show noteworthy assets being fast-paced with high-speed electronics and low power consumption, one of which are high-efficient solar cells at a moderate price. Developing electric devices it turns
Morphology and facet engineering have been proved efficient strategies to prepare high-performance photoelectrochemical (PEC) materials. WO3/BiVO4 heterojunction photoanodes with different morphologies were prepared by simply controlling the amount of electrodeposited charge. The coral-like WO3/BiVO4 photoanode with the orientation growth of {110} and {011} active facets of BiVO4 exhibited the opt
The European Spallation Source (ESS) is a neutron science facility funded by a collaboration of 17 European countries currently under design and construction in Lund, Sweden. The centerpiece of ESS is a 2.5 GeV proton linac utilizing superconducting RF cavities operating at 2 K. In addition to cooling the SRF cavities, cryogenics is also used at ESS in the liquid hydrogen moderators surrounding th
Popular Abstract in Swedish Nanoteknologi handlar om att på ett kontrollerat sätt utnyttja strukturer med minst en dimension i nanometerområdet (i storleksordningen 1 till 100 miljondels millimeter). Nanostrukturer har använts under lång tid och redan under medeltiden användes guldpartiklar av varierande storlek för att tillverka infärgade glas. Idag använder vi nanoteknologi dagligdags, t.ex. i vThis dissertation deals with the geometric and electronic structure of surfaces on III–V semiconductor nanowires (NWs). NWs made of InAs, GaAs, and InP have been studied using scanning tunneling microscopy/spectroscopy (STM/S), low energy electron microscopy (LEEM), photoemission electron microscopy (PEEM), and x-ray photoelectron spectroscopy (XPS). All of the mentioned techniques have been devel
We have used synchrotron X-ray diffraction experiments to measure the strain field introduced by a hydride blister grown on a section of a pressure tube from a CANDU nuclear reactor. After charging the tube section with a homogeneous hydrogen concentration of 300 wt ppm, the blister was produced by creating a small cold spot on its surface (similar to 200 degrees C), while the bulk was kept at a t
Popular Abstract in Swedish Glatt muskulatur är nödvändig för funktionen hos de flesta inre organ såsom blodkärl, tarmar, gallblåsa, livmoder, urin och luftvägar. I artärer bildar glatta muskelceller ett cirkulärt lager, som skiljs från blodet genom ett tunt endotelcellslager. Muskelns främsta uppgift är att kontrollera blodkärlens diameter, och därmed blodflödet till de vävnader som de försörjer.Intracellular Ca2+ is a key regulator of vascular contractility, and thereby of blood perfusion and pressure. Ca2+ signals are essential also for cell migration, proliferation and regulation of numerous enzymes. Besides producing vascular contraction smooth muscle cells may also modulate to a synthetic phenotype and proliferate as an initial stage in the atherosclerotic proce
Background: Caldicellulosiruptor saccharolyticus has attracted increased interest as an industrial hydrogen (H2)producer. The aim of the present study was to develop a kinetic growth model for this extreme thermophile. The model is based on Monod kinetics supplemented with the inhibitory effects of H2 and osmotic pressure, as well as the liquid-to-gas mass transfer of H2. Results: Mathematical exp
Popular Abstract in Undetermined Most of the things that we use daily are the product of chemical reactions. Plastics derive from the polymerization of smaller molecules, drugs are synthesised rigorously by pharmaceutical industries, and products for the house and personal care contain a number of different chemicals and fragrances. All these compounds are produced by different branches of the cheWith the emergence of Green Chemistry, biocatalysis is becoming an important approach in many laboratory and industrial processes. Enzymes catalyse chemical reactions with high regio- and stereoselectivity at mild conditions and, most importantly, are able to form products that are not possible to obtain by conventional synthetic chemistry. Monooxygenases are a fascinating group of enzymes which o
Novel soil remediation equipment based on electro-kinetic geosynthetics (EKG) was developed for in situ isolation of metals from paddy soil. Two mutually independent field plot experiments A and B (with and without electric current applied) were conducted. After saturation using ferric chloride (FeCl3) and calcium chloride (CaCl2), soil water drainage capacity, soil cadmium (Cd) removal performanc
Limiting global warming to ‘safe’ levels will require rapid and radical reductions of greenhouse gas emissions across all sectors of the global economy. The discontinuation of incumbent industrial structures, that will be an unavoidable part of such sustainability transitions, will disproportionally burden certain groups. Recent events including the social and political unrest linked to the immine
The attachment of the 2,2′-bipyridine (bpy) moieties to the surface of planar silicon(111) (photo)electrodes was investigated usingab initiosimulations performed on a new cluster model for methyl-terminated silicon. Density functional theory (B3LYP) with implicit solvation techniques indicated that adventitious chlorine atoms, when present in the organic linker backbone, led to instability at very
Energy is the essential requirement of humans. It plays a major role in the development of any country. The present status of crude oil import of India in the financial year 2018-19 was around 22,64,98,000 MT of Rs. 7,83,183 crore and other fuels like LPG, MS, Naphtha, ATF, etc. were around 3,33,48,000 MT of Rs. 1,13,665 crore [1] and the total installed capacity of India is around 3,65,981.00 MW
This paper estimates how electricity price divergence within Sweden has affected incentives to invest in photovoltaic (PV) generation between 2016 and 2022 based on a synthetic control approach. Sweden is chosen as the research subject since it is the only member of the European Union with multiple bidding zones (BZ) that faces dramatic price divergence between low-tariff BZ in Northern and high-t
The transition from fossil jet fuel to biojet fuel is an important step towards reducing greenhouse gas (GHG) emissions from aviation. To enable such a fuel shift, the Swedish Government introduced a GHG emission reduction mandate of 27% by 2030 for aviation fuel sold in Sweden, forcing fuel suppliers to blend in biojet fuel in fossil jet fuel. A similar policy instrument is being discussed within
För att motverka den globala uppvärmningen sker i nuläget en övergång till förnybara energikällor, bland annat genom att injicera biometan i naturgasnätet. Integrationen av gas från olika källor har dock lett till ett problem: svavelutfällningar. Detta fenomen kan leda till att rör och utrustning går sönder och inte fungerar som de ska, samt en hälsorisk för operatörerna. År 2021 upptäcktes svavTo mitigate global warming, a shift towards renewable energy sources is in motion, including introducing biomethane into natural gas grids. However, the integration of gas from various sources has led to a problem known as elemental sulphur deposition. This phenomenon may lead to the breakdown and malfunction of pipes and equipment, posing health hazards to operators. In 2021 solid sulphur depos
