Oil has been for the past 50 years the most widely used energy source. That is because oil contains a lot of energy and is easy to transport and store. But the use of oil has drawbacks; it is believed to change the earth’s climate due to the combustion and the emissions of the green house gases. The particles from the combustion cause problems for the human health. Today Oil accounts for 33 % of t

The [NiFe] hydrogenases catalyse the reversible conversion of H2 to protons and electrons. The active site consists of a Fe ion with one carbon monoxide, two cyanide, and two cysteine (Cys) ligands. The latter two bridge to a Ni ion, which has two additional terminal Cys ligands. It has been suggested that one of the Cys residues is protonated during the reaction mechanism. We have used combined q

Development of environmentally friendly and cost-efficient energy sources has been a challenge for modern society since long ago. Sunlight is an infinite and costless source of energy on Earth, so it would be an enormous advantage to efficiently harvest and transform it into electrical energy used in our everyday life. In nature the process, which converts light energy into chemical energy, is cal

The paper describes a project aiming at constructing functional mimics of the oxygen evolving complex in photosystem II, coupled to photoinduced charge separation. Biomimetic electron donors, manganese complexes and tyrosine, have been linked to a Ru(II)-polypyridine photosensitiser. Oxidation of the donors by intramolecular electron transfer from the photooxidised Ru(III) complex was demonstrated

Calcium precipitation can have a number of effects on the performance of high-rate anaerobic performance including cementing of the sludge bed, limiting diffusion, and diluting the active biomass. The aim of this study was to observe the influence of precipitation in a stable full-scale system fed with high-calcium paper factory wastewater. Granules were examined from an upflow anaerobic sludge bl

The atmospheres of close-in planets are strongly influenced by mass loss driven by the high-energy (X-ray and extreme ultraviolet, EUV) irradiation of the host star, particularly during the early stages of evolution. We recently developed a framework to exploit this connection and enable us to recover the past evolution of the stellar high-energy emission from the present-day properties of its pla

Natural light-harvesting is performed by pigment–protein complexes, which collect and funnel the solar energy at the start of photosynthesis. The identity and arrangement of pigments largely define the absorption spectrum of the antenna complex, which is further regulated by a palette of structural factors. Small alterations are induced by pigment–protein interactions. In light-harvesting systems

Adsorbed organic compounds modify the properties of environmental interfaces with potential implications for many Earth system processes. Here, we describe experimental studies of water interactions with acetic acid (AcOH) layers on ice and graphite surfaces at temperatures from 186 to 200 K. Hyperthermal D2O water molecules are efficiently trapped on all of the investigated surfaces, with only a

Oxidation of NH3/n-heptane mixtures at pressures up to 100 atm and temperatures of 400–900 K was characterized experimentally in a laminar flow reactor and a jet-stirred reactor. A detailed chemical kinetic model was developed, updating the hydrogen and amine subsets and introducing a subset for the chemical coupling with emphasis on the NH2+n-heptane reaction. The kinetic model provided a good pr

High-resolution O 1s resonant inelastic x-ray scattering spectra of liquid H2O, D2O, and HDO, obtained by excitation near the preedge resonance show, in the elastic line region, well-separated multiple vibrational structures corresponding to the internal OH stretch vibration in the ground state of water. The energy of the first-order vibrational excitation is strongly blueshifted with respect to t

Solen har lyst konstant på vår värld i fyra och en halv miljard år. Strålarna som värmer vår hud idag har känts av varenda person som någonsin levt. Solens strålar har rört vid dinosaurier, och hälsat på de första varelser som lämnade havens vatten för ett liv på land.Solen har varit vittne till allting som skett här på Jorden. Men den är ingen passiv iakttagare. Solen är vår planets kraftverk, deThe Sun has shone on our world for four and a half billion years. The light that warms our skin today has been felt by every person who has ever lived.It is our nearest star and our planet’s powerhouse, the source of the energy that drives our winds, our weather and all life.The passage of the Sun’s fiery disc across the sky — day by day, month by month — was the only way to keep track of time for

As part of the Net-Zero Industry Act and Industrial Carbon Management Strategy, the European Union (EU) has positioned carbon capture and storage (CCS) as a critical decarbonization technology. These developments build on the European Green Deal's (EGD) integrated approach to climate policy, which seeks to balance decarbonization with broader societal goals. Previous research confirms CCS's techni

Internal dynamics of dansylated poly(propyleneamine) dendrimers (POPAM, G1-G4) in solution and excitation energy transfer from dansyls to eosin in POPAM-eosin complexes have been studied by time-resolved fluorescence spectroscopy and molecular dynamics (MD) simulations. Combining the results from fluorescence anisotropy and the MD simulation studies suggests three time domains for the internal dyn

The UN Sustainable Development Goal (SDG) 7 states that access to affordable, reliable, sustainable, and modern energy should be provided for all by 2030. The effects on socioeconomic development by access to safe, affordable, and clean electricity stands out as educational benefits, income improvement, and health progress. However, the electrification rate has been slow for sub-Saharan Africa and
