Carbon capture and storage technologies (CCS) are being discussed and tested in different countries to reduce industrial emissions. Public opinion about industrial CCS (iCCS) can be a key factor in whether it will be implemented. Yet, measuring public acceptance of CCS is a challenge: on the one hand, the use of CCS is the subject of intense and controversial political debate. On the other hand, a
[NiFe] hydrogenases catalyze the reversible conversion of molecular hydrogen to protons and electrons. This seemingly simple reaction has attracted much attention because of the prospective use of H2 as a clean fuel. In this paper, we have studied the full reaction mechanism of this enzyme with various computational methods. Geometries were obtained with combined quantum mechanical and molecular m
Todays society is moving towards electrification. This means that more renewable energy is needed. In the southern parts of Sweden the energy consumption is far greater than the production and the electricity prices are rising. Sysav is a company that takes care of the waste and recycling. They have 16 facilities in the south of Skåne, including landfills. Sysav has a vision to contribute to the r
A ternary Mg2COH5 hydride was synthesized using a novel method that relies on a relatively short mechanical milling time (1 h) of a 2:1 MgH2-Co powder mixture followed by sintering at a sufficiently high hydrogen pressure (>85 bar) and heating from RT to 500 degrees C. The ternary hydride forms in less than 2.5 h (including the milling time) with a yield of similar to 90% at similar to 300 degrees
Maximizing ultrafast electron-transfer kinetics in semiconductor is pivotal but challenging for high-efficiency solar-to-energy during the photocatalytic reaction process due to the intrinsic property of photocatalysts with low surface electron density. Herein, a model photocatalyst CdS@Mo is synthesized through a typical hydrothermal method for modulating the ultrafast electron-transfer to enhanc

This seminar series is organized by the three nanoscience hubs located in the Copenhagen-Lund area. The aim is to to increase awareness about our mutual capabilities and to inspire collaborations. Below, please find the talk abstracts and short bio of the speakers on the Photoluminescence topic. Within a radius of just 25 km, the Copenhagen-Lund region features three strong hubs for nanoscience, w

Biomass derived gases produced via gasification, pyrolysis, and fermentation are carbon neutral alternative fuels that can be used in gas turbines, furnaces, and piston engines. To make use of these environmentally friendly but energy density low fuels the combustion characteristics of these fuels have to be fully understood. In this study the structure and laminar burning velocity of biomass deri
At many storage rings for synchrotron light production there is demand for serving both high-flux and timing users simultaneously. Today this is most commonly achieved by operating inhomogeneous fill patterns, but this is not preferable for rings that employ passive harmonic cavities to damp instabilities and increase Touschek lifetime. For these rings, inhomogeneous fill patterns could severely r
Using Ambient Pressure X-ray Photoelectron Spectroscopy (APXPS), this study investigates the reduction behavior of iron oxides in direct reduction (DRI) and blast furnace (BF) pellets. H2, CO, and a H2–CO mixture are used as reducing agents at 650 °C. The investigation aimed to elucidate variations in the rate of reduction over time and under different conditions. Additionally, contour plots are g
Uranium atoms activate methane upon ultraviolet excitation to form the methyl uranium hydride CH3-UH, which undergoes alpha-H transfer to produce uranium methylidene dihydride, CH2UH2. This rearrangement most likely occurs on an excited-quintet potential-energy surface and is followed by relaxation in the argon matrix. These simple U + CH4 reaction products are identified through isotopic substitu
The accumulated experience and path-dependent development of petroleum-based transport fuels and internal combustion engine vehicles has created an apparent technological lock-in. Our analysis of a RApid Future vehicles and Fuels scenario (RAFF) for the EU shows that ambitious carbon emission reductions can be achieved even with projected increases in road transport. Furthermore, escaping the lock
Developing new and useful methods in asymmetric catalysis is of continuous importance. A current challenge is to address the imperatives of green chemistry, such that processes maximize resource-efficiency and minimize the generation of waste. To this end, this article discloses the potential of alpha-amino acids in the development of entropy-controlled and enantiodivergent Lewis acid catalysis. I
Heme oxygenase is an enzyme that degrades heme, thereby recycling iron in most organisms, including humans. Pervious density functional theory (DFT) calculations have suggested that iron(III) hydroxyheme, an intermediate generated in the first step of heme degradation by heme oxygenase, is converted to iron(III) superoxo oxophlorin in the presence of dioxygen. In this article, we have studied the

Combustion of NH3 with H2 addition can improve the combustion stability. In this study, the laminar burning velocities (LBVs) of NH3/H2/O2/CO2 mixtures were determined under atmospheric pressure and an initial temperature of 303 K by the heat flux method, spanning CO2 fractions of 0.50-0.75, H2 fractions of 0.20-0.70, and equivalence ratios of 0.6-1.5. Evaluations of three kinetic models (modified
