Boosting Formic Acid Production in Mildly Acidic Media - The Role of Native Surface Oxide on the CO2 Reduction Performance
No full text<p>Raw data for the publication DOI: <a title="DOI URL" href="https://doi.org/10.1021/acsomega.5c10136">https://doi.org/10.1021/acsomega.5c10136</a></p><p>Bismuth catalysts hold significant promise for the electroreduction of CO<sub>2</sub> to formic acid (FA), yet their performance in acidic electrolytes remains largely unexplored despite clear advantages for product separation and direct industrial integration. Here, we systematically investigate the catalytic activity and long-term stability of bismuth catalysts under acidic conditions (pH 3). At this pH, the hydrogen evolution reaction bifurcates into distinct proton and water reduction pathways, with the CO<sub>2</sub> reduction reaction to FA taking place exactly between them. We demonstrate that bismuth catalysts efficiently suppress the proton reduction, leading to over 95% selectivity towards FA in acidic media. Furthermore, long-term measurements reveal the governing catalytic role of an inherently formed surface oxide, which develops upon catalyst ink preparation in ambient air, even if metallic bismuth is used as catalyst. This is evidenced by cyclic voltammetry, X-Ray photoelectron spectroscopy and potentiostatic product detection via online gas chromatography. Our work reports on successful electrocatalytic formic acid production from CO<sub>2</sub> at pH 3, which opens viable pathways for the implementation of this reaction through proton-exchange membrane technologies.</p>

Selective cyclized peptide κ-opioid receptor antagonist - in vivo pharmacology
No full text<p>Modulating the GPCR k-opioid receptor is a promising strategy for treating CNS disorders, where the receptor antagonism is associated with beneficial effects for the treatment of mood and psychiatric diseases, and drug addictive disorders. Behavioral investigations in mice established the in vivo k-opioid receptor antagonist properties of CSD-CH2(1,8)-NH2 after subcutaneous administration in mice based on its ability to reverse the antinociceptive effects of the prototypical k-opioid agonist, U50,488, in a model of acute thermal nociception (the radiant heat tail-flick assay) and to prevent sedation/motor impairment produced by U50,488 in the rotarod test. CSD-CH2(1,8)-NH2 had in vivo antagonist activity by modulating k-opioid receptor function in the CNS.</p>
<p>The dataset includes experimental in vivo pharmacological data on CSD-CH2(1,8)-NH2, a selective cyclized peptide κ-opioid receptor antagonist. </p>

<p> </p>
<p><strong>Overview</strong></p>
<p>The rainfal and subsurface stormflow data were collected in the Black Forest (south of Freiburg, Germany). Subsurface stormflow was measured at two trenched hillslopes. Rainfall and subsurface stormflow events were delineated and their characteristics computed. For more info refere to the readme file and associated study. </p>

Diisopromine as a non-labelled CYP3A4 substrate: Implications for breath test development
No full text<p>LC-data:</p>
<p>The data used for the experiments are available in CSV files. As many control measurements were carried out, there are often more data in the files than was used for analysis. Except from the area comparison, each file contains a calibration, as well as blank and unknown sample measurements. The data were measured using a Vanquish HPLC Flex system with a binary pump, coupled to an Orbitrap Q-Exactive mass spectrometer (both from Thermo Fisher Scientific). Evaluation was performed using the ‘QuanBrowser’ software (Thermo Xcalibur 4.2.47, Thermo Fisher Scientific). See the following publication for more information: https://doi.org/10.1016/j.bioorg.2025.108772</p>
<p>PTR-data:</p>
<p>The data used for the experiments are available as .txt files. As many control measurements were carried out, there are often more data in the files than was used for analysis. The data were measured using a PTR-ToF 6000 X2 (Ionicon Analytik GmbH, Innsbruck, Austria). The data obtained from these measurements were analysed using PTR-ToF-MS Viewer software (version 3.4.4.22, Ionicon Analytik GmbH) and saved as a .txt file. The acetone product ion signal (C₃H₇O⁺) was normalised to a reagent ion signal of 10⁶ ions per second, in accordance with the following publication: https://doi.org/10.1016/j.bioorg.2025.108772</p>

Impact of stress-regulated growth factor signaling on lipidomic profiles
No full text<p>Cytotoxic stress and survival signaling mediated by growth factors are intricately intertwined, influencing cellular lipid metabolism and composition through mechanisms that remain incompletely understood. These datasets present changes in lipidomic profiles across multiple experimental models (based on fibroblasts, cancer cell lines, primary cells, and <i>C. elegans</i>), providing insights into the underlying biological processes. Metadata, including details on sample treatment, preparation, and analytical methods, are embedded within the data files.</p>
