The copper coordination geometry in the blue copper proteins plastocyanin, nitrite reductase, cucumber basic protein, and azurin has been studied by combined density functional (B3LYP) and molecular mechanical methods. Compared to quantum chemical vacuum calculations, a significant improvement of the geometry is seen (toward the experimental structures) not only for the dihedral angles of the liga
The Asian steel industry produces 73 % of global steel and is expanding. The speed and plans for decarbonizing the Asian steel sector are thus globally important. Importing green Hot Briquetted Iron (HBI), iron ore reduced to iron with renewable hydrogen, from renewable-rich countries such as Australia, Brazil and South Africa, could be a good option to avoid constraints with access to renewables.

We present and study a minimal structure-based model for the self-assembly of peptides into ordered β-sheet-rich fibrils. The peptides are represented by unit-length sticks on a cubic lattice and interact by hydrogen bonding and hydrophobicity forces. Using Monte Carlo simulations with >10^{5} peptides, we show that fibril formation occurs with sigmoidal kinetics in the model. To determine the mec

Context. The Si III] 1892 angstrom intercombination line shows an anomalously high intensity in spectra of the radiation-rich Weigelt blobs in the vicinity of Eta Carinae. The line disappears during the 100 days long spectral events occurring every 5.5 years. Aims. The aim is to investigate whether resonance-enhanced two-photon ionization (RETPI) is a plausible excitation mechanism for the Si III]
Popular Abstract in Swedish Syftet med studierna som presenteras i denna avhandling har varit att undersöka om fordonsetanol kan framställas på ett lönsamt och energieffektivt sätt från restprodukter från jord- och skogsbruk enligt svenska förhållanden. Mycket av den forskning som rör andra-generationens etanolproduktion går ut på att förfina och förbättra de separata delstegen i framställningsproSweden has claimed that it wants to have a fossil-free vehicle fleet in 2030 as a milestone of its ambitious goal for 2050 to be a country with a sustainable and resource-efficient energy supply without any net GHG emissions. Production of bioethanol from plant materials is one potential method of meeting this goal. A large amount of research has been devoted toward the development of sustainable
The photoactivity of rutile TiO2(110) renders its surfaces of particular interest for the study of surface reactions. In particular, rutile TiO2(110) surfaces are active for hydrogen production, both via the water splitting process and via ethanol degradation under ultraviolet illumination. The selective photocatalytic dehydrogenation of rutile TiO2(110) is not fully understood yet, and an importa
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
Fuel cells are promising for future energy systems, because they are energy efficient and able to use renewable fuels. A fully coupled computational fluid dynamics (CFD) approach based on the finite element method (with the software COMSOL Multiphysics) in two-dimensions is developed to describe an intermediate temperature solid oxide fuel cell (SOFC) single cell. Governing equations covering heat

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
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
A reduced four-step scheme for Computational Fluid Dynamics (CFD) analysis is presented here in the context of industrial type laboratory combustor. The present scheme has been optimized for a syngas mixture consisting of 10% CH4, 22.5% CO and 67.5% H2 by volume, and for a methane-air mixture. The optimization of the global scheme is done by comparing with the detailed San Diego mechanism using pe
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
En grundläggande princip inom konkursrätten är att konkursboet inte ansvarar för gäldenärens tidigare förpliktelser. Miljörätten däremot är uppbyggd runt syftet att kunna utkräva ansvar från en stor krets av fysiska och juridiska personer, detta i syfte att skydda nuvarande och kommande generationer. Det problematiska är att kombinera dessa två lagstiftningar och syften. Syftet för den här framsA fundamental principle within the bankruptcy law is that the bankruptcy estate is not responsible for the debtor’s prior obligations. The environmental law is built around the purpose of enabling the enforcement system to demand accountability from a large group of corporations and persons. This, for the purpose of protecting present and future generations. An important matter is how to combine t
