title: Dynamic vs. Stationary Analysis of Electrochemical Carbon Dioxide Reduction: Strong Differences in Local State

description: Experimental Details: All electrochemical measurements were conducted in a three-electrode. As a working electrode, a planar silver rotating disk electrode (surface area A = 0.1963 cm²), and as counter electrode, a spiral platinum wire was used. All potentials were measured and plotted against a reversible hydrogen electrode reference electrode (RHE). The potentials were corrected for uncompensated resistance afterward. The electrolyte was purged with CO₂ for 15 min before starting the experiment to ensure saturation with CO₂. Cyclic voltammetry was performed in a potential window of -0.5 to -2.0 V vs. RHE with rotation speeds between 50 and 150 rpm and between -0.5 to -2.5 V vs. RHE for 300 rpm. The scan rate of the potential sweep was set to values of 50, 100, 200 and 300 mV/s. The number of cycles was eight for each scan rate to guarantee a quasi-steady state. In the figures, only the last cycle is displayed. The stationary polarization curve was measured by holding a constant potential for 200 s. The step size of the applied potential was 0.1 V. The uncompensated resistance was measured after each holding time. Figures show the corrected mean potential and mean error, determined from the last 20 s of each measured potential. Numerical Details: The model was implemented in MATLAB R2020b, and differential equations were solved with ode15s solver. Spatial discretization was done with an equidistant grid and applying finite volume method and central differential quotients. Grid size was set to a value of Δx=1 µm and convergence of the solution regarding grid parameters was confirmed as refining the parameters lead to no visual changes of the cyclic voltammograms and concentration profiles. The system was initialized by holding the starting potential of -0.5 V, where no significant electrochemical reactions take place, until a stationary state was reached. Initial surface coverages and initial potential of the electrode were adapted from the stationary state. Initial concentrations were set to electrolyte bulk concentrations, where equilibrium of carbonate species and dissolved CO₂ is adjusted.

title: Effect of baking lipases on the lipidome of cake

description: Lipases are promising improvers of cake batter and baking properties. Their suitability for use in various cake formulations cannot be predicted yet, because the reactions that lead to macroscopic effects need to be unravelled. Therefore, the lipidome of three different cake recipes with and without lipase treatment was assessed by ultra high performance liquid chromatography-mass spectrometry before and after baking. By comparing the reaction patterns of seven different lipases in the recipes with known effects on texture, we show that lipase substrate specificity impacts baking quality. Key reactions for the recipes were identified with the help of principal component analysis. In the eggless basic cake, glyceroglycolipids are causal for baking improvement. In pound cake, lysoglycerophospholipids were linked to textural effects. Lipase substrate specificity was shown to be dependent on the recipe. Further research is needed to understand how recipes can be adjusted to achieve optimal lipase substrate specificity for desirable batter and baking properties.
description: The results are combined in three zip files, named according to the recipe. Within each zip file, samples are named according to the following procedure: Recipe (BC for basic cake, PC for pound cake or B for brioche); Product (c for cake, alias baked product and d for dough/batter); Treatment (Blank for untreated sample, A-O for lipase or QC for quality control); Replicate (a-c for triplicate and s for spiked sample a). e.g. sample BCdE_b is a batter sample of basic cake treated with lipase E

title: Electrochemical Investigation of Calcium Substituted Monoclinic Li3V2(PO4)3 Negative Electrode Materials for Sodium- and Potassium-Ion Batteries

description: Herein, the electrochemical properties and reaction mechanism of Li3-2xCaxV2(PO4)3/C (x = 0, 0.5, 1, and 1.5) as negative electrode materials for sodium-ion/potassium-ion batteries (SIBs/PIBs) are investigated. All samples undergo a mixed contribution of diffusion-controlled and pseudocapacitive-type processes in SIBs and PIBs via Trasatti Differentiation Method, while the latter increases with Ca content increase. Among them, Li3V2(PO4)3/C exhibits the highest reversible capacity in SIBs and PIBs, while Ca1.5V2(PO4)3/C shows the best rate performance with a capacity retention of 46% at 20 C in SIBs and 47% at 10 C in PIBs. This study demonstrates that the specific capacity of this type of material in SIBs and PIBs does not increase with the Ca-content as previously observed in lithium-ion system, but the stability and performance at a high C-rate can be improved by replacing Li+ with Ca2+. This indicates that insertion of different monovalent cations (Na+/K+) can strongly influence the redox reaction and structure evolution of the host materials, due to the larger ion size of Na+ and K+ and their different kinetic properties with respect to Li+. Furthermore, the working mechanism of both LVP/C and Ca1.5V2(PO4)3/C in SIBs are elucidated via in operando synchrotron diffraction and in operando X-ray absorption spectroscopy.

title: Electrochemical study on Nickel Aluminum Layered Double hydroxides as high-performance electrode material for lithium-ion batteries based on sodium alginate binder

description: Nickel aluminum layered double hydroxide (NiAl LDH) with nitrate in its interlayer is investigated as a negative electrode material for lithium-ion batteries (LIBs). The effect of the potential range (i.e., 0.01 – 3.0 V and 0.4 – 3.0 V vs. Li+/Li) and of the binder on the performance of the material is investigated in 1 M LiPF6 in EC/DMC vs. Li. The NiAl LDH electrode based on sodium alginate (SA) binder shows a high initial discharge specific capacity of 2586 mAh g-1 at 0.05 A g-1 and good stability in the potential range of 0.01-3.0 V vs. Li+/Li, which is better than what obtained with a polyvinylidene difluoride (PVDF)-based electrode. The NiAl LDH electrode with SA binder shows, after 400 cycles at 0.5 A g-1, a cycling retention of 42.2 % with a capacity of 697 mAh g-1 and at a high current density of 1.0 A g-1 shows a retention of 27.6 % with a capacity of 388 mAh g-1 over 1400 cycles. In the same conditions, the PVDF-based electrode retains only 15.6 % with a capacity of 182 mAh g-1 and 8.5 % with a capacity of 121 mAh g-1, respectively. Ex situ X-ray photoelectron spectroscopy (XPS) and ex situ X-ray absorption spectroscopy (XAS) reveal a conversion reaction mechanism during Li+ insertion into the NiAl LDH material. X-ray diffraction (XRD) and XPS have been combined with the electrochemical study to understand the effect of different cut-off potentials on the Li-ion storage mechanism.

title: Electron-momentum dependence of electron-phonon coupling underlies dramatic phonon renormalization in YNi2B2C

description: Electron-phonon coupling, i.e., the scattering of lattice vibrations by electrons and vice versa, is ubiquitous in solids and can lead to emergent ground states such as superconductivity and charge-density wave order. A broad spectral phonon line shape is often interpreted as a marker of strong electron-phonon coupling associated with Fermi surface nesting, i.e., parallel sections of the Fermi surface connected by the phonon momentum. Alternatively broad phonons are known to arise from strong atomic lattice anharmonicity. Here, we show that strong phonon broadening can occur in the absence of both Fermi surface nesting and lattice anharmonicity, if electron-phonon coupling is strongly enhanced for specific values of electron-momentum, k. We use inelastic neutron scattering, soft x-ray angle-resolved photoemission spectroscopy measurements and ab-initio lattice dynamical and electronic band structure calculations to demonstrate this scenario in the highly anisotropic tetragonal electron-phonon superconductor YNi$_2$B$_2$C. This new scenario likely applies to a wide range of compounds.

title: Enguri Catalog KIT (Version 2023-03-14)

description: In the frame of the DAMAST (Dams and Seismicity) (https://www.damast-caucasus.de/) project we deployed a dense high-fidelity seismological real-time network to investigate in detail the spatio-temporal seismicity distribution around the Enguri high dam, situated in the greater Caucasus in western Georgia. We aim at recording the weak seismicity in a 10 km distance around the dam structure. We installed an 8-station local seismic network to record weak seismicity in 10 km around the dam, with good coverage and high sensitivity around Ingirishi fault segments. To lower the detection threshold by reducing the ambient background noise, we installed four seismic stations in shallow (ca. 20 m) and deep boreholes. From these stations, KIT1 with a depth of ca. 250 m is the deepest seismological station in Georgia. The network installation was performed in three main stages, October 2020, December 2020, and September 2021. The published catalog, which is a collaboration between Geophysical Institute of KIT, and M. Nodia Institute of Geophysics, I. Javakhishvili Tbilisi State University (TSU), includes preliminary processing results of 316 earthquakes occurred between October 2020 to July 2022, within the longitude range between 41.64 and 42.34, and the latitude range between 42.53 and 43. For each event, origin time, latitude, longitude, depth (km), number of stations, GAP, RMS, magnitude (if applicable) and magnitude type are given. A 1-D velocity model of the upper mantle in Caucasus and adjacent regions is employed for the location process (Murusidze., G. 1987). Pg- and Sg-phases are manually picked using SEISAN-Earthquake analysis software (Havskov and Ottemoller, 1999.) and for each event, local magnitude (Ml) is estimated using S-phase amplitude read on both horizontal components. The catalog is presented and discussed in detail in Karamzadeh et. al 2023.

title: Electrostatic Ignition (Summary of experiment series E4.3 results)

description: Work package four of the PRESLHY project focuses on ignition phenomena. This report summarises the experimental series E4.3, which focuses on the propensity for an electrostatic charge capable of igniting a hydrogen cloud to be generated during a release, or accidental spill scenario. Seven experiments measuring the electric field of a multiphase hydrogen jet were conducted at the HSE Science and Research Centre. Current measurements on an electrically isolated section of steel pipework were also taken during a total of 30 large scale releases. The results from the plume measurements indicate that the multiphase hydrogen jet itself does not create a significant charge, but certain interactions with the air can cause intermittent spikes in field strength. In particular, air in the pipework being ejected and solidified air forming around the release point, breaking off and flowing downstream appear to be the cause of the electrical fields measured in these experiments. This effect could be larger with different initial conditions either at the nozzle or in the tanker. The wall current measurements were more consistent, as the ability for LH 2 to induce a current on a section of electrically insulated pipework was clearly demonstrated. This charge is a complicated function of the phase of LH 2 in the pipework, the turbulence of the flow, and the resistance to ground of the section of the pipework. Frost formation on the outside of the pipework dynamically changed the resistance to ground throughout each trial, making interrogation of the results difficult. The experiments show that electrostatic charges do pose a credible hazard when considering LH 2 facilities. The charging, however, does not form inside the hydrogen, but on the substances or objects that the hydrogen interacts with. For a fixed facility, maintaining continuity to earth, paying attention to objects in the potential path of a release, would limit the likelihood of electrostatic charging and therefore limit the hazard.
