Two-dimensional coherent electronic spectrometer with switchable multi-color configurations [research data] Mar 25, 2024 - SFB 1249: N-Heteropolyzyklen als Funktionsmaterialien - B: Theory & Structure Kefer, Oskar; Kolesnichenko, Pavel V.; Buckup, Tiago, 2024, "Two-dimensional coherent electronic spectrometer with switchable multi-color configurations [research data]", https://doi.org/10.11588/data/BLXCSM, heiDATA, V1 Broadband implementation of two-dimensional electronic spectroscopy (2DES) is a desirable goal for numerous research groups, yet achieving it presents considerable challenges. An effective strategy to mitigate these challenges is the utilization of two-color approaches, effective...
Triggered contraction of self-assembled micron-scale DNA nanotube rings [Research Data] Feb 16, 2024 - Göpfrich Group - Biophysical Engineering of Life Illig, Maja; Jahnke, Kevin; Weise, Lukas P.; Scheffold, Marlene; Mersdorf, Ulrike; Drechsler, Hauke; Zhang, Yixin; Diez, Stefan; Kierfeld, Jan; Göpfrich, Kerstin, 2024, "Triggered contraction of self-assembled micron-scale DNA nanotube rings [Research Data]", https://doi.org/10.11588/data/ADYUNN, heiDATA, V1, UNF:6:AJdXI51lTUqvs4V/XCVPZQ== [fileUNF] Contractile rings formed from cytoskeletal filaments mediate the division of cells. Ring formation is induced by specific crosslinkers, while contraction is typically associated with motor protein activity. Here, we engineer DNA nanotubes as mimics of cytoskeletal filaments and a...
Thermolysis of Biphenylene toward Cyclo-ortho-phenylenes [data] Mar 4, 2024 - Bunz Group Ehjeij, Daniel; Rominger, Frank; Bunz, Uwe; Freudenberg, Jan; Müllen, Klaus, 2024, "Thermolysis of Biphenylene toward Cyclo-ortho-phenylenes [data]", https://doi.org/10.11588/data/AYVNYK, heiDATA, V1 The solvent and catalyst free thermolysis of biphenylenes at 350 °C furnishes [n]cyclo-ortho-phenylenes ([n]COPs, n=4–10) in one step and in high yields. At 400 °C biphenylene dimerizes into tetraphenylene, but lower reaction temperatures produce cyclooligomers. If suitably subst...
The illusory certainty: Information repetition and impressions of truth enhance subjective confidence in validity judgments independently of the factual truth [Dataset] Jan 23, 2024 - Psychological Research Methods Stump, Annika; Voss, Andreas; Rummel, Jan, 2024, "The illusory certainty: Information repetition and impressions of truth enhance subjective confidence in validity judgments independently of the factual truth [Dataset]", https://doi.org/10.11588/data/WDQJWW, heiDATA, V1 People not only judge repeatedly perceived information as more likely being true (the so-called truth effect) they also tend to be more confident after judging the validity of repeated information. These phenomena are assumed to be caused by a higher subjective feeling of ease (i...
The contribution of drug import to the cost of tuberculosis treatment: a cost analysis of longer, shorter and short drug regimens for Karakalpakstan, Uzbekistan [Research Data] Apr 18, 2024 - Global Health and Economics Kohler, Stefan; Sitali, Norman; Achar, Jay; Paul, Nicolas, 2024, "The contribution of drug import to the cost of tuberculosis treatment: a cost analysis of longer, shorter and short drug regimens for Karakalpakstan, Uzbekistan [Research Data]", https://doi.org/10.11588/data/LTTWSQ, heiDATA, V1 Tuberculosis (TB) programs depend on a continuous supply of large amounts of high-quality TB drugs. When TB programs procure TB drugs from international suppliers, such as the Global Drug Facility, they can incur import costs for international transport, customs clearance, and na...
