Aside from solution NMR, an increasing number of studies have been conducted applying solid-state magic-angle spinning (MAS) NMR to fluorine-labelled samples. Here, the high chemical shift anisotropy and strong dipolar couplings can be utilised to get structural insights into proteins and measure long distances. Despite increasing popularity and promising benefits, the sensitivity of biomolecular 19F MAS NMR often suffers from slow longitudinal T1 relaxation and therefore long recycle delays. In this work, we expand paramagnetic doping, an approach commonly used to reduce proton T1 relaxation times, to 19F-labelled biological samples. We study the effect of Gd(DTPA) and Gd(DTPA-BMA) on 19F T1 and T2, and 13C T1 and T2 relaxation in a [5-19F13C]-tryptophan-labelled protein via 19F-detected MAS NMR experiments. The observed paramagnetic relaxation enhancement substantially reduces measurement times of 19F MAS NMR experiments without compromising resolution. Additionally, we report the chemical shift assignments of all four fluorotryptophan signals in the 12×39 kDa-large protein TET2 using a mutagenesis approach."}],"quality_controlled":"1","author":[{"full_name":"Becker, Lea Marie","last_name":"Becker","orcid":"0000-0002-6401-5151","first_name":"Lea Marie","id":"36336939-eb97-11eb-a6c2-c83f1214ca79"},{"full_name":"Toscano, Giorgia","id":"334a5e40-8747-11f0-b671-ba1f5154b4b4","first_name":"Giorgia","last_name":"Toscano"},{"last_name":"Kapitonova","id":"9fb2a840-89e1-11ee-a8b7-cc5c7ba62471","first_name":"Anna","full_name":"Kapitonova, Anna"},{"first_name":"Rajkumar","id":"a3089acd-6806-11ee-bacc-f0c7d500ad20","last_name":"Singh","full_name":"Singh, Rajkumar"},{"full_name":"Guillerm, Undina","last_name":"Guillerm","id":"bb74f472-ae54-11eb-9835-bc9c22fb1183","first_name":"Undina"},{"first_name":"Roman J.","last_name":"Lichtenecker","full_name":"Lichtenecker, Roman J."},{"full_name":"Schanda, Paul","last_name":"Schanda","id":"7B541462-FAF6-11E9-A490-E8DFE5697425","first_name":"Paul","orcid":"0000-0002-9350-7606"}],"department":[{"_id":"PaSc"},{"_id":"GradSch"}],"tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"publisher":"Copernicus Publications","article_type":"original","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","page":"29-37","_id":"21777","intvolume":"         7","date_published":"2026-04-16T00:00:00Z","pmid":1,"acknowledgement":"We thank Ben P.

Here, we provide a quantitative estimate of the carbon emissions associated with conference attendance by analyzing travel data from participants of 10 international conferences in the field of magnetic resonance, namely EUROMAR, ENC and ICMRBS. We find that attending a EUROMAR conference produces, on average, more than 1 t CO2 eq.. For the analyzed conferences outside Europe, the corresponding value is about 2–3 times higher, on average, with intercontinental trips amounting to up to 5 t. We compare these conference-related emissions to other activities associated with research and show that conference travel is a substantial portion of the total climate footprint of a researcher in magnetic resonance. We explore several strategies to reduce these emissions, including the impact of selecting conference venues more strategically and the possibility of decentralized conferences. Through a detailed comparison of train versus air travel – accounting for both direct and infrastructure-related emissions – we demonstrate that train travel offers considerable carbon savings. These data may provide a basis for strategic choices of future conferences in the field and for individuals deciding on their conference attendance."}],"quality_controlled":"1","department":[{"_id":"JoFi"},{"_id":"GaTk"},{"_id":"JoCs"},{"_id":"EvBe"},{"_id":"TaHa"},{"_id":"GradSch"},{"_id":"GeKa"},{"_id":"PaSc"}],"tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"author":[{"first_name":"Lucky","id":"84b9700b-15b2-11ec-abd3-831089e67615","orcid":"0000-0001-8319-2148","last_name":"Kapoor","full_name":"Kapoor, Lucky"},{"full_name":"Ruzickova, Natalia","first_name":"Natalia","id":"D2761128-D73D-11E9-A1BF-BA0DE6697425","last_name":"Ruzickova"},{"full_name":"Zivadinovic, Predrag","last_name":"Zivadinovic","id":"68AA0E5A-AFDA-11E9-9994-141DE6697425","first_name":"Predrag"},{"full_name":"Leitner, Valentin","last_name":"Leitner","id":"4c665ce3-0016-11ec-bea0-e44de7a4fa3d","first_name":"Valentin"},{"last_name":"Sisak","first_name":"Maria A","id":"44A03D04-AEA4-11E9-B225-EA2DE6697425","full_name":"Sisak, Maria A"},{"last_name":"Mweka","first_name":"Cecelia N","id":"2a69ab4b-896a-11ed-bdf8-cb8641cf2b21","full_name":"Mweka, Cecelia N"},{"last_name":"Dobbelaere","id":"c15a5412-de82-11ed-b809-8dc1aa996e40","first_name":"Jeroen A","full_name":"Dobbelaere, Jeroen A"},{"full_name":"Katsaros, Georgios","orcid":"0000-0001-8342-202X","id":"38DB5788-F248-11E8-B48F-1D18A9856A87","first_name":"Georgios","last_name":"Katsaros"},{"id":"7B541462-FAF6-11E9-A490-E8DFE5697425","orcid":"0000-0002-9350-7606","first_name":"Paul","last_name":"Schanda","full_name":"Schanda, Paul"}],"related_material":{"link":[{"url":"https://ista.ac.at/en/news/carbon-footprint-of-conference-travel/","description":"News on ISTA website","relation":"research_data"}],"record":[{"id":"20242","status":"public","relation":"research_data"}]},"title":"Quantifying the carbon footprint of conference travel: The case of NMR meetings","publication_identifier":{"eissn":["2699-0016"]},"corr_author":"1","type":"journal_article"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_type":"original","publisher":"Copernicus Publications","date_published":"2024-06-11T00:00:00Z","pmid":1,"_id":"17161","intvolume":"         5","page":"69-86","date_created":"2024-06-23T22:01:02Z","issue":"1","scopus_import":"1","language":[{"iso":"eng"}],"acknowledgement":"We would like to thank Kay Saalwächter for pointing out important aspects of the intermediate regime during the open review process.

For spin relaxation, this can easily be understood from the sampling frequencies of the spectral-density function by different relaxation-rate constants. In addition to data from relaxation measurements, determining dynamically averaged anisotropic interactions in magic-angle spinning (MAS) solid-state NMR allows for better quantification of the amplitude of molecular motion. For partially averaged anisotropic interactions, the relevant timescales of motion are not so clearly defined. Whether the averaging depends on the experimental methods (e.g., pulse sequences) or conditions (e.g., MAS frequency, magnitude of anisotropic interaction, radio-frequency field amplitudes) is not fully understood. To investigate these questions, we performed numerical simulations of dynamic systems based on the stochastic Liouville equation using several experiments for recoupling the dipolar coupling, chemical-shift anisotropy or quadrupolar coupling. As described in the literature, the transition between slow motion, where parameters characterizing the anisotropic interaction are not averaged, and fast motion, where the tensors are averaged leading to a scaled anisotropic quantity, occurs over a window of motional rate constants that depends mainly on the strength of the interaction. This transition region can span 2 orders of magnitude in exchange-rate constants (typically in the microsecond range) but depends only marginally on the employed recoupling scheme or sample spinning frequency. The transition region often coincides with a fast relaxation of coherences, making precise quantitative measurements difficult. Residual couplings in off-magic-angle experiments, however, average over longer timescales of motion. While in principle one may gain information on the timescales of motion from the transition area, extracting such information is hampered by low signal-to-noise ratio in experimental spectra due to fast relaxation that occurs in the same region.","lang":"eng"}],"department":[{"_id":"PaSc"}],"tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"author":[{"first_name":"Kathrin","last_name":"Aebischer","full_name":"Aebischer, Kathrin"},{"full_name":"Becker, Lea Marie","last_name":"Becker","id":"36336939-eb97-11eb-a6c2-c83f1214ca79","first_name":"Lea Marie","orcid":"0000-0002-6401-5151"},{"full_name":"Schanda, Paul","last_name":"Schanda","id":"7B541462-FAF6-11E9-A490-E8DFE5697425","first_name":"Paul","orcid":"0000-0002-9350-7606"},{"first_name":"Matthias","last_name":"Ernst","full_name":"Ernst, Matthias"}],"has_accepted_license":"1","year":"2024","citation":{"ama":"Aebischer K, Becker LM, Schanda P, Ernst M.
