The work presented in this thesis is based on time-resolved x-ray diffraction studies of InSb (111) samples. The experiments were carried out using a pump-probe configuration using short laser pulses as the pump and x-rays as the probe. Laser excitation leads to the formation of a strain pulse that propagates through the sample. The strain pulse gives rise to coherent longitudinal, acoustic phonon

In this study, batch biohydrogen production by co-digestion of raw rice straw and activated sewage sludge was investigated with different inoculum heat treatment, pH, S/X ratio (based on VS) and substrate sizes under mesophilic condition. In order to achieve a high bio-hydrogen yield and methanogens activity inhibition, heat treatment of inoculum was optimized at different exposure times (30, 45 &

Popular Abstract in Swedish Arbetet som presenteras i denna avhandling handlar om att utveckla nya processer för att producera gasformiga biobränslen som är mer energieffektiva än de som används idag. Genom att göra processerna mer energieffektiva kan kostnaden för att producera biobränslen minskas. En lägre produktionskostnad för biobränslet gör det lättare att ersätta fossila bränslen med förnyeReplacing fossil fuels with biofuels is one way of reducing the emission of greenhouse gases into the atmosphere, thus decreasing our impact on the global climate. For this to be a viable option, several production routes are needed, as no single option can fully replace fossil fuels. One way of making biofuels more competitive with fossil fuels is by reducing the production cost. As most of the p

The compounds (a) (H3O)2[Mo6Cl8 Cl6]·7H2O, (b) (H3O)2[Mo6 Cl8Br6]·6H2O and (c) (H3O)2[Mo6 Cl8I6].6H2O were synthesized from MoCl2 and the corresponding halide acid. The structures were determined by X-ray diffraction and refined in the monoclinic space groups, (a) C2/c and for (b) and (c) P21/a. The cell parameters were for (a), a = 17.3607(2), b = 9.1351(7), c = 18.6300(2) Å and β = 98.13(1)°, (b

Three new cobalt complexes of the general formula [CoIII(L)Cl]2+, where L is one of five pentadentate nitrogen-donor ligands based on the N4Py framework, have been synthesized and characterized fully by UV−visible and NMR spectroscopies, high-resolution electrospray ionization mass spectrometry (HRESI-MS), X-ray crystallography, and electrochemistry. The electrocatalytic capabilities of these comp

The growing energy demand and the impact of polluting gases lead to the necessity of alternative energy sources and conversion energy devices. Fuel cells (FCs) appears as a suitable solution for facing the mentioned issues. Predicting the behavior of a polymer electrolyte fuel cell (PEFC) under different conditions represents a proper initial step to solve the several issues, e.g., aging water bal

In this paper, a novel membrane reactor (MR) for methanol steam reforming is modeled to produce fuel cell grade hydrogen, which can be used as the inlet fuel for a later developed 500-W horizon polymer electrolyte fuel cell (PEFC) stack. The backpropagation (BP) neural network algorithm is employed to develop the mapping relation model between the MR's prime operational parameters and fuel cell ou

The steel industry emits 2,400–2,713 Mt CO2 and 12 Mt of fugitive methane globally each year, yet progress towards decarbonization has been limited. In this Review, we examine the potential, feasibility and barriers to decarbonization of the steel sector. The blast furnace–basic oxygen furnace (BF–BOF) accounts for ~72% of global steel production and has the highest carbon emission intensity of ex

Large science publisher Elsevier does not meet the requirements of Swedish universities and research institutes. The agreement was cancelled 30th of June. This means that employees and students at Lund University do not have access to journal articles published by Elsevier after June 30, 2018.

Popular Abstract in English Popular Science Abstract In our daily routines, we use products and come across applications that involve mixtures of polymers and small amphiphilic molecules in water, for example detergents, pharmaceutics, foodstuffs, shampoos and paints. Polymers are very large molecules formed by smaller units that are repeated and connected. Amphiphilic molecules contain both one pThe research described in this thesis aims to understand the interactions between cationic poly(amidoamine) (PAMAM) dendrimers and small oppositely charged amphiphiles at the solid-liquid and air-liquid interfaces in relation to the bulk solution behavior. There is high interest in PAMAM dendrimers because they are well-defined polymers with a hierarchical architecture which makes them promising m

Sorption-enhanced steam reforming (SorESR) is an advanced thermochemical process integrating in-situ CO2 capture via solid sorbents to significantly enhance hydrogen production and purity. By coupling CO2 adsorption with steam reforming, SorESR shifts the reaction equilibrium toward increased H₂ yield, surpassing the limitations of conventional steam reforming (SR). The efficacy of SorESR critical

The currently most promising approach for reducing CO2 emissions of the global steel production is reducing iron ore in shaft furnaces with (green) hydrogen instead of blast furnaces. Unlike to the liquid iron produced in blast furnaces, the direct reduced iron produced in this route (green iron) exists in a solid state and can be transported at reasonable costs over long distances. This allows fo

The membrane is often considered as the heart of the proton exchange membrane fuel cell (PEMFC), and it is of pivotal importance for the involved transport phenomena and performance of the entire PEMFC. The Nafion(R) membrane is the most commonly used type of membrane in PEMFCs. In this paper, the nano-scale structure of the Nafion(R) membrane is reconstructed using dissipative particle dynamics.
