Au uniaxial compression in x-direction 10 % engineering strain

Wolfram G. Nöhring, Adam R. Hinkle & Lars Pastewka
This surface is the result of a Molecular Dynamics simulation of uni-axial compression of single crystal Au. The initial configuration was an Au cube with side length 100 nm. The x- and y-directions of the simulation cell were parallel to the [-110] and [-1-12] directions of the crystal, respectively. The z-direction was parallel to the [111] crystal direction. The x- and y-directions were periodic, but the z-direction was free, hence the crystal had free surfaces...

Performance of manganese oxide sorbents for direct lithium extraction from geothermal brines

Klemens Slunitschek , Jochen Kolb & Elisabeth Eiche
Lithium is one of the critical elements for the realization of electric mobility and energy transition. With a contribution to global Li-production and recycling of less than 1% (2017), Europe depends almost entirely on Li-import. To reduce the dependency, new and unconventional Li resources are explored in the EU. One resource are highly saline brines from geothermal reservoirs of the Upper Rhine Graben (URG), characterized by Li concentrations of up to 200 mg/L. Due to...

Comparison of high-resolution SIMS profiles with maximum resolution IRMS stable isotope data

Tobias Kluge , Philipp Holz , Elisabeth Eiche , Thomas Neumann , Alexander Land , Maximilian Schuh , Mario Trieloff & Axel K. Schmitt
High-resolution speleothem paleoclimate records with annual to seasonal resolution are helpful for detailed analysis of climatic changes with limited duration (e.g., volcanic climate impacts), but also for longer-duration events (e.g., at 8.2 ka or 4.2 ka). A high resolution paleoclimate data set is also mandatory for meaningful comparison with archaeological or historical records. Low stalagmite growth rates could impede the acquisition of high-resolution isotope data with the classical micro-milling approach and isotope ratio mass spectrometry...

The fate of crustal xenoliths in carbonatite dykes of the Gross Brukkaros, Namibia

Rebecca Ruwe , Johannes Giebel & Benjamin F. Walter
The Gross Brukkaros (Namibia) reflects a broad dome structure showing a crater-shaped depression with numerous peripheral beforsitic carbonatite dykes. These dykes frequently contain an extreme load of basement (Nama-group) xenoliths (> 60 vol.%) including shales, quartzites, granites and gneisses. While xenoliths of exposed country rocks (mainly shales) show an angular habit, a pronounced rounding of xenoliths from other lithologies proves a wide transport and strong abrasion. This consumption of xenolithic material may result in remarkable...

Structural modelling of Agbada (Tertiary) sandstone reservoirs in “Atled Creek”, Onshore Niger Delta, Nigeria

Olajide Jonathan Adamolekun , Benjamin Busch , Idongesit Akwaowoh , Michael P. Suess & Christoph Hilgers
The distribution of rocks and rock properties is an important part of an overall strategy for reservoir development, placement of new wells and prediction of future production. It also provides a detailed look into the local development of a sedimentary basin. Here we present a case-study from the “Atled Creek” concession, onshore Nigeria. A 3D structural reservoir model of the concession was prepared from available industry seismic data and well logs. Four sandstone reservoirs within...

Metallic raw material demand for hydrogen technology in the German steel production 2030

Katharina Steiger , Jochen Kolb & Christoph Hilgers
To reach Germany’s climate neutrality goal in 2045, different technological and systematical changes have to be conducted, such as the expansion of renewable energies plants, the shift towards e-mobility and the necessary infrastructure. For the measures, metallic raw materials will be increasingly required. The German government plans to support those industry sectors, which are emitting great amounts of CO2. The data evaluation on emissions and energy consumption in Germany shows that the sector "production and...

Ground Motion Emissions from Wind Turbines: State of the Art and Implications

Joachim Ritter & Laura Gassner
Wind turbines are massive tall buildings which swing considerably above the ground, especially when they are in operation. These oscillations are composed of the eigenmodes of the whole building and the interaction of the passing blades with the tower. The oscillations are transferred into the ground by interaction of the moving foundation with the ground (soil / rock). The radiated wavefield is composed of elastic waves, conformable to seismic waves. Mainly surface waves are excited...

How much royalties are paid for hydrocarbon and lignite explorations in Germany?

Philipp Blum & Frederic Berger
The Federal Mining Act (Bundesberggesetz, BBergG) was introduced to govern the use of the German subsurface. By paying royalties, companies obtain permissions to exploit resources in Germany. However, there is no transparent reporting on the paid royalties yet. Hence, the objective of this study is to provide an overview of the ownership and paid royalties. Furthermore, we discuss the sustainable use and management of the German subsurface. Our study shows that the subsurface is partly...

Platelet membrane-camouflaged nanoparticles carry microRNA inhibitor against myocardial ischaemia‒reperfusion injury

Tianyi Wang, Tingting Zhou, Mingming Xu, Shuo Wang, Anqi Wu, Mingyang Zhang, You Lang Zhou & Jiahai Shi
Abstract The incidence of myocardial ischaemia‒reperfusion injury (MIRI) is increasing every year, and there is an urgent need to develop new therapeutic approaches. Nrf2 is thought to play a protective role during MIRI and it is regulated by microRNAs (miRNAs). This study focused on PLGA nanoparticles camouflaged by platelet membrane vesicles (PMVs) (i.e., PMVs@PLGA complexes) carrying microRNA inhibitors, which regulate Nrf2 and can play a therapeutic role in the MIRI process. In vitro and in...

The assessment of the long-term stability of geological units in the context of subsurface use is a complex topic in which various geoscientific and technical aspects play an important role. For example, the geomechanical stability of radioactive waste repositories due to endogenous, exogenous and engineering processes is an important aspect in the long term. For a stability prognosis, an estimation of the recent stress state as well as an assessment of realistic future stress changes...

Optimization of l-malic acid production from acetate with Aspergillus oryzae DSM 1863 using a pH-coupled feeding strategy

Aline Kövilein, Vera Aschmann, Lena Zadravec & Katrin Ochsenreither
Abstract Background Malic acid, a dicarboxylic acid mainly used in the food industry, is currently produced from fossil resources. The utilization of low-cost substrates derived from biomass could render microbial processes economic. Such feedstocks, like lignocellulosic hydrolysates or condensates of fast pyrolysis, can contain high concentrations of acetic acid. Acetate is a suitable substrate for l-malic acid production with the filamentous fungus Aspergillus oryzae DSM 1863, but concentrations obtained so far are low. An advantage...

Standortsuche im Spannungsfeld

Oliver Heidbach, Moritz Ziegler, Sophia Morawietz, Karsten Reiter, Luisa Röckel & Fabrice Cotton
Das gegenwärtige Spannungsfeld der Erdkruste ist eine zentrale Feldgröße für die Beurteilung der Stabilität eines Endlagers. Erreichen die Spannungen einen kritischen Wert, dann versagt das Gestein. Es bilden sich Risse und Brüche, die Wegsamkeiten für Flüssigkeiten und Gase darstellen. Als Folge kann das Endlager undicht werden. Im direkten Bezug dazu stehen die Ausschlusskriterien seismische Aktivität und aktive Störungszonen aus dem Standortauswahlgesetz. Beide sind ein Ausdruck dafür, dass der kritische Wert überschritten wurde.
