Lauer, Jochen C.; Bhat, Avinash S.; Barwig, Chantal; Rominger, Frank; Mastalerz, Michael, 2022, "[2+3] Amide Cages by Oxidation of [2+3] Imine Cages - Revisiting Molecular Hosts for Efficient Nitrate Binding [Data]", https://doi.org/10.11588/data/HWLKZT, heiDATA, V1
The pollution of groundwater with nitrate is a serious issue because nitrate can cause several diseases such as methemoglobinemia or cancer. Therefore, selective removal of nitrate by efficient binding to supramolecular hosts is highly desired. Here we describe how to make [2+3]... |

Yang, Xuan; Elbert, Sven Michael; Rominger, Frank; Mastalerz, Michael, 2022, "A Series of Soluble Thieno-fused Coronene Nanoribbons of Precise Lengths [Data]", https://doi.org/10.11588/data/30AOAT, heiDATA, V1
Among graphene nanoribbons (GNRs), reports on coronene-based GNRs were very rare, despite the unique optoelectronic properties of coronene. Herein, the synthesis of a series of structurally precise and soluble thieno-fused coronene nanoribbons (CR-1 to CR-4) with up to four coron... |

Becker, Christoph K.; Trautmann, Stefan T., 2022, "Does Happiness Increase in Old Age? Longitudinal Evidence from 20 European Countries [Dataset]", https://doi.org/10.11588/data/CVMANS, heiDATA, V1
Several studies indicate that happiness follows a U-shape over the life cycle: Happiness decreases after the teenage years until reaching its nadir in middle age. A similar number of studies views the U-shape critically, stating that it is the result of the wrong controls or the... |

Tian, Ke; Elbert, Sven Michael; Hu, Xinyue; Kirschbaum, Tobias; Zhang, Wen-Shan; Rominger, Frank; Schröder, Rasmus R.; Mastalerz, Michael, 2022, "Highly Selective Adsorption of Perfluorinated Greenhouse Gases by Porous Organic Cages [Data]", https://doi.org/10.11588/data/O9I5UP, heiDATA, V1
Anthropogenic greenhouse gases contribute to global warming. Among those gases, perfluorocarbons (PFCs) are thousands to tens of thousands times more harmful to the environment than comparable amounts of carbon dioxide. Till date, materials that selectively adsorb perfluorocarbon... |

Einzmann, Teresa; Schroll, Moritz; Kleint, Jan Frederik; Greule, Markus; Keppler, Frank, 2022, "Application of concentration and 2-dimensional stable isotope measurements of methane to constrain sources and sinks in a seasonally stratified freshwater lake [data]", https://doi.org/10.11588/data/KLFDVF, heiDATA, V1, UNF:6:v5med6vrABS01PP8hfg5JQ== [fileUNF]
Methane (CH4) emissions from aquatic systems have recently been comprised to account for up to 50 % of global CH4 emissions, with lakes representing one of the largest CH4 source within this pool. However, there is large uncertainty associated with CH4 emissions from freshwater e... |

Hsu, Li-Yun; Mainik, Philipp; Münchinger, Alexander; Lindenthal, Sebastian; Spratte, Tobias; Welle, Alexander; Zaumseil, Jana; Selhuber-Unkel, Christine; Wegener, Martin; Blasco, Eva, 2022, "A Facile Approach for 4D Microprinting of Multi-Photoresponsive Actuators [data]", https://doi.org/10.11588/data/MR5H4A, heiDATA, V1
For microscale 4D photoresponsive actuators, light is crucial in two ways. First, the underlying additive manufacturing techniques rely on photopolymerization processes triggered by the absorption of light. Second, the absorption of light serves as the actuation stimulus. The two... |
Merkel-Hilf, Nicole, 2022, "Ground Truth data for printed Devanagari", https://doi.org/10.11588/data/EGOKEI, heiDATA, V1
