This process can be viewed as performing hundreds of parallel reactions programmed on a self‐assembled nanoscale platform. While previous studies have focused on investigating the collective results of the chemical or enzymatic ligation reactions, herein, the global quantitative analysis of individual ligation reactions is achieved using quantitative PCR (qPCR). By mapping enzymatic ligation efficiency on a trapezoidal substructure representing one‐third of a triangular DON, ligation is shown to preferentially occur at the trapezoid edges rather than at inner sites. Excellent agreement between the experimental ligation yields and docking simulations suggests that this is a result of variations in the ligase docking probability. Ligation products involving more than two consecutive sequences can be generated with each enzyme‐catalyzed reaction as an independent event. Interestingly, the sharp contrast between the edges vs. the inner sites has been abolished by changing the reaction conditions and performing the ligation in a DMSO co‐solvent system. This analytic method provides unprecedented insight into the multiple ligation reactions occurring in parallel within complex DONs and will be an invaluable tool in the translation of DONs from the lab to real‐world applications.</jats:p>"}],"publication":"Small","citation":{"short":"K.

Additionally, they also possess excellent photocatalytic activity and stability in the process of dechlorination of chlorophenols, which are typical persistent organic pollutants. It would be of great interest to conduct in situ (photo‐) catalysis investigations during the whole photocatalytic process by SHG when considering them as photocatalytic materials. In order to get superior photocatalytic efficiency and maximum surface information, small particles are highly desired. Here, a low‐cost and fast synthesis route that allows growing microcrystalline optically nonlinear Pb<jats:sub>2</jats:sub>B<jats:sub>5</jats:sub>O<jats:sub>9</jats:sub>X borate halides at large quantities is introduced. When applying the ionothermal growth process at temperatures between 130 and 170 °C, microcrystallites with an average size of about 1 µm precipitate with an orthorhombic hilgardite‐like borate halide structure. Thorough examinations using powder X‐ray diffraction and scanning electron microscopy, the Pb2B5O9X microcrystals are indicated to be chemically pure and single‐phased. Besides, the Pb2B5O9X borate halides' SHG efficiencies are confirmed using confocal SHG microscopy. The low‐temperature synthesis route thus makes these borate halides a highly desirable material for surface studies such as monitoring chemical reactions with picosecond time resolution and in situ (photo‐) catalysis investigations.</jats:p>","lang":"eng"}],"publication":"Small","issue":"23","keyword":["Biomaterials","Biotechnology","General Materials Science","General Chemistry"],"type":"journal_article","date_created":"2023-10-11T08:07:50Z","publication_status":"published","date_updated":"2023-10-11T08:09:29Z","article_type":"original","intvolume":"        16","year":"2020","title":"Resource‐Efficient Low‐Temperature Synthesis of Microcrystalline Pb2B5O9X (X = Cl, Br) for Surfaces Studies by Optical Second Harmonic Generation","author":[{"full_name":"Tan, Deming","first_name":"Deming","last_name":"Tan"},{"full_name":"Kirbus, Benjamin","first_name":"Benjamin","last_name":"Kirbus"},{"id":"22501","first_name":"Michael","last_name":"Rüsing","orcid":"0000-0003-4682-4577","full_name":"Rüsing, Michael"},{"last_name":"Pietsch","first_name":"Tobias","full_name":"Pietsch, Tobias"},{"full_name":"Ruck, Michael","first_name":"Michael","last_name":"Ruck"},{"full_name":"Eng, Lukas M.","first_name":"Lukas M.","last_name":"Eng"}],"publication_identifier":{"issn":["1613-6810","1613-6829"]},"doi":"10.1002/smll.202000857","article_number":"2000857","language":[{"iso":"eng"}]},{"page":"1702100","_id":"22668","language":[{"iso":"eng"}],"user_id":"48864","doi":"10.1002/smll.201702100","volume":13,"status":"public","year":"2017","title":"Cation-Induced Stabilization and Denaturation of DNA Origami Nanostructures in Urea and Guanidinium Chloride","publication_identifier":{"issn":["1613-6810"]},"author":[{"last_name":"Ramakrishnan","first_name":"Saminathan","full_name":"Ramakrishnan, Saminathan"},{"full_name":"Krainer, Georg","first_name":"Georg","last_name":"Krainer"},{"last_name":"Grundmeier","first_name":"Guido","full_name":"Grundmeier, Guido","id":"194"},{"last_name":"Schlierf","first_name":"Michael","full_name":"Schlierf, Michael"},{"full_name":"Keller, Adrian","first_name":"Adrian","orcid":"0000-0001-7139-3110","last_name":"Keller","id":"48864"}],"publication_status":"published","date_updated":"2022-01-06T06:55:38Z","intvolume":"        13","date_created":"2021-07-08T12:38:10Z","type":"journal_article","department":[{"_id":"302"}],"publication":"Small","citation":{"mla":"Ramakrishnan, Saminathan, et al. “Cation-Induced Stabilization and Denaturation of DNA Origami Nanostructures in Urea and Guanidinium Chloride.” <i>Small</i>, vol. 13, 2017, p. 1702100, doi:<a href=\"https://doi.org/10.1002/smll.201702100\">10.1002/smll.201702100</a>.","ama":"Ramakrishnan S, Krainer G, Grundmeier G, Schlierf M, Keller A.
