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." article_number: e08136 author: - first_name: Konrad full_name: Hacker, Konrad last_name: Hacker - first_name: Emilia full_name: Juricke, Emilia id: '68157' last_name: Juricke - first_name: Carolin full_name: Münch, Carolin last_name: Münch - first_name: Antonio full_name: Suma, Antonio last_name: Suma - first_name: Adrian Clemens full_name: Keller, Adrian Clemens id: '48864' last_name: Keller orcid: 0000-0001-7139-3110 - first_name: Yixin full_name: Zhang, Yixin last_name: Zhang citation: ama: Hacker K, Juricke E, Münch C, Suma A, Keller AC, Zhang Y.

Especially for 2D materials, the atomic electric fields influence the optoelectronic properties. In this study, the atomic‐scale electric field and charge density distribution of WSe2 bi‐ and trilayers are revealed using an emerging microscopy technique, differential phase contrast (DPC) imaging in scanning transmission electron microscopy (STEM). For pristine material, a higher positive charge density located at the selenium atomic columns compared to the tungsten atomic columns is obtained and tentatively explained by a coherent scattering effect. Furthermore, the change in the electric field distribution induced by a missing selenium atomic column is investigated. A characteristic electric field distribution in the vicinity of the defect with locally reduced magnitudes compared to the pristine lattice is observed. This effect is accompanied by a considerable inward relaxation of the surrounding lattice, which according to first principles DFT calculation is fully compatible with a missing column of Se atoms. This shows that DPC imaging, as an electric field sensitive technique, provides additional and remarkable information to the otherwise only structural analysis obtained with conventional STEM imaging. author: - first_name: Maja full_name: Groll, Maja last_name: Groll - first_name: Julius full_name: Bürger, Julius last_name: Bürger - first_name: Ioannis full_name: Caltzidis, Ioannis last_name: Caltzidis - first_name: Klaus D. full_name: Jöns, Klaus D. last_name: Jöns - first_name: Wolf Gero full_name: Schmidt, Wolf Gero last_name: Schmidt - first_name: Uwe full_name: Gerstmann, Uwe last_name: Gerstmann - first_name: Jörg 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 Pb2B5O9X 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. article_number: '2000857' article_type: original author: - first_name: Deming full_name: Tan, Deming last_name: Tan - first_name: Benjamin full_name: Kirbus, Benjamin last_name: Kirbus - first_name: Michael full_name: Rüsing, Michael id: '22501' last_name: Rüsing orcid: 0000-0003-4682-4577 - first_name: Tobias full_name: Pietsch, Tobias last_name: Pietsch - first_name: Michael full_name: Ruck, Michael last_name: Ruck - first_name: Lukas M. full_name: Eng, Lukas M. last_name: Eng citation: ama: Tan D, Kirbus B, Rüsing M, Pietsch T, Ruck M, Eng LM.
