--- _id: '60973' abstract: - lang: eng text: The specific binding of DNA origami nanostructures (DONs) to bacteria is an important prerequisite for their application in pathogen targeting and antimicrobial drug delivery. So far, targeting bacteria with DONs has been achieved exclusively via aptamers, which suffer from drawbacks such as sensitivity toward environmental conditions and reduced binding after immobilization or conjugation. Here, an alternative approach is presented based on the modification of DONs with the cell wall‐binding glycopeptide antibiotic vancomycin. Using strain‐promoted azide‐alkyne cycloaddition, azide‐modified vancomycin is conjugated to selected staple strands and subsequently incorporated into 2D DON triangles. The resulting constructs show specific binding to the Gram‐positive species Bacillus subtilis (B. subtilis) and Staphylococcus capitis (S. capitis), and remarkably, to Gram‐negative Escherichia coli (E. coli), but no antimicrobial activity at vancomycin concentrations up to at least 2.91 μM. For B. subtilis and E. coli, DONs with vancomycin modifications on both sides exhibit better binding than DONs modified on only one side. However, both variants bind equally well to S. capitis. These results demonstrate the great potential of small molecule drug compounds for the robust, broad‐spectrum targeting of bacteria with DONs. Targeting a ubiquitous cell wall component of most pathogenic bacteria, vancomycin‐modified DONs have many potential applications in the prevention and treatment of nosocomial infections. article_number: '2500246' author: - first_name: Özge full_name: Coşkuner Leineweber, Özge last_name: Coşkuner Leineweber - first_name: Bhanu K. full_name: Pothineni, Bhanu K. last_name: Pothineni - first_name: Nils full_name: Schumann, Nils last_name: Schumann - first_name: Ulrike full_name: Hofmann, Ulrike last_name: Hofmann - first_name: Christin full_name: Möser, Christin last_name: Möser - first_name: David M. full_name: Smith, David M. last_name: Smith - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier - first_name: Yixin full_name: Zhang, Yixin last_name: Zhang - first_name: Adrian full_name: Keller, Adrian id: '48864' last_name: Keller orcid: 0000-0001-7139-3110 citation: ama: Coşkuner Leineweber Ö, Pothineni BK, Schumann N, et al.

While previous work utilized various DON modifications, simple methods for controlling their landing orientation remain scarce. Here, we demonstrate a straightforward approach to control the adsorption orientation of chiral double‐L (CDL) DON on mica by tuning magnesium ion (Mg2⁺) concentration and exploiting global shape distortions. Using atomic force microscopy (AFM), we analyzed the resulting distribution of the mirror‐image orientations, referred to as S and Z orientations, at both buffer/mica and air/mica interfaces and identified conditions resulting in homogenous CDL orientation of 100% S. These results demonstrate how DON conformation and ionic environments influence DON orientation, offering insights for precise nanostructure deposition. article_number: e202507613 author: - first_name: Gangamallaiah full_name: Velpula, Gangamallaiah last_name: Velpula - first_name: Emilia full_name: Tomm, Emilia last_name: Tomm - first_name: Boxuan full_name: Shen, Boxuan last_name: Shen - first_name: Kunal S. full_name: Mali, Kunal S. last_name: Mali - first_name: Adrian Clemens full_name: Keller, Adrian Clemens id: '48864' last_name: Keller orcid: 0000-0001-7139-3110 - first_name: Steven full_name: De Feyter, Steven last_name: De Feyter citation: ama: Velpula G, Tomm E, Shen B, Mali KS, Keller AC, De Feyter S.

Herein, a novel protocol is reported for the synthesis of amidines based on PIII/PVO redox catalysis. This two‐step, one‐pot approach involves the activation of amides via PIII/PVO catalyzed in situ formation of imidoyl chloride intermediates which are directly converted upon reaction with amines into the corresponding amidines. Instead of traditionally used toxic and corrosive chloride sources, hexachloroacetone (HCA) is successfully employed as a halide source. The reaction proceeds with low catalyst loading (2 mol%) in BuOAc as the solvent. Under the optimized conditions, 20 amidines are prepared in yields up to 99%. A feasible mechanism is proposed based on experimental results. The synthetic potential of this method is evaluated in the preparation of the tyrosine kinase inhibitor (TKI) Erlotinib. article_number: '202500394' author: - first_name: Viktorija full_name: Medvaric, Viktorija id: '92677' last_name: Medvaric - first_name: Jan full_name: Paradies, Jan id: '53339' last_name: Paradies orcid: 0000-0002-3698-668X - first_name: Thomas full_name: Werner, Thomas id: '89271' last_name: Werner orcid: 0000-0001-9025-3244 citation: ama: Medvaric V, Paradies J, Werner T.

However, as a by‐product of pulp and paper industry, it is mainly burned for energy. Limited understanding of the complex and heterogeneous structure and a shortage of tailored analysis methods hinder its utilization in higher value applications. This study describes and compares the use of two different static light scattering methods, laser diffraction and small‐angle light scattering (SALS), for studying lignin particle size in suspension. The results from laser diffraction showed that the selected particle concentration and absorption coefficient affect the measured sizes especially for particles <1 µm in diameter. For irregularly shaped particles with broad size distributions, sampling is the most important parameter affecting the results. SALS proved an efficient method for obtaining information on particle aggregation by providing primary particle sizes as well as aggregate sizes. Characterization of samples with spherical particles and narrow size distributions is straightforward with both laser diffraction and SALS, whereas the interpretation of results for more heterogeneous samples is less obvious. Static light scattering methods could make lignin particle size analysis more rapid and automated, thus enhancing lignin valorization, but should be applied carefully to avoid systematic errors. article_number: e00085 author: - first_name: Janita full_name: Makkonen, Janita last_name: Makkonen - first_name: Patrik full_name: Ahvenainen, Patrik last_name: Ahvenainen - first_name: Stefania full_name: Bertella, Stefania last_name: Bertella - first_name: Miriam full_name: Kellock, Miriam last_name: Kellock - first_name: Sanjib full_name: Saha, Sanjib last_name: Saha - first_name: Klaus full_name: Huber, Klaus id: '237' last_name: Huber - first_name: Muhammad full_name: Farooq, Muhammad last_name: Farooq - first_name: Monika full_name: Österberg, Monika last_name: Österberg - first_name: Paavo full_name: Penttilä, Paavo last_name: Penttilä citation: ama: Makkonen J, Ahvenainen P, Bertella S, et al.

Previous studies of this transformation were conducted at lower current densities than those of industrial relevance (≥1 A cm–2). We used ultramicroelectrodes (UMEs) to achieve such current densities, benefiting from their small size, ensuring low absolute currents and low ohmic drop but high current densities. Morphological degradation of the catalyst material was only observed at current densities exceeding 1 A cm–2 but not for smaller ones. Using X-ray absorption, X-ray photoemission spectroscopy, and X-ray diffraction, we confirmed that the degradation was accompanied by the literature-known transformation of nanoparticulate Ni3Se2 (bulk)/NiSe (surface) into nickel oxyhydroxide. The transformation of the precatalyst goes along with a significant improvement in the charge transfer kinetics observed by decreasing Tafel slopes with ongoing experimental time extracted from cyclic voltammetry (CV) experiments and electrochemical impedance spectroscopy (EIS) in the high-frequency range. However, these kinetic improvements are accompanied by limitations in mass transport concluded from decreasing current responses at high overpotentials in CVs and increasing impedance in the low-frequency range of the EIS spectra after extended CV cycling. These mass transport limitations originated from morphological degradations at the UME exceeding 1 A cm–2 which we proved by applying identical location scanning electron microscopy. This has not been reported in studies that have been limited to lower current densities before. Our findings showcase how UMEs can be used to study (pre)catalysts (herein nickel selenides) under current densities of industrial relevance in the absence of ohmic drop-related ambiguities, combined with in-depth materials characterization studies, e.g., identical location microscopy and advanced spectroscopic methods. This approach enables direct evaluation and comparison of catalyst materials and thus demonstrates how to overcome long-standing limitations of electrocatalyst design and testing. article_type: original author: - first_name: Felix full_name: Hiege, Felix last_name: Hiege - first_name: Chun-Wai full_name: Chang, Chun-Wai last_name: Chang - first_name: Oliver full_name: Trost, Oliver last_name: Trost - first_name: Charlotte E.

At 25 °C, an increase in RH from 60% to 93% resulted in an obvious proton conducting switch from 9.1 × 10−11 to 5.6 × 10−5 S cm−1 for 1 and from 7.4 × 10−10 to 1.8 × 10−6 S cm−1 for 2, corresponding to high on/off ratios of about 106 for 1 and 104 for 2. In situ powder X-ray diffraction (PXRD) analysis showed that unit cell parameters of compounds 1 and 2 slightly increase when exposed to humid conditions. This confirmed that incorporation of water molecules into structures with pores and voids causes the proton conductivity switching phenomenon. Magnetic susceptibility measurements indicate a ferromagnetic interaction between Cr3+ and Mn2+ ions bridged by the bis(bidentate) oxalate group. The prepared compounds 1 and 2 were explored as single-source precursors for the formation of spinel oxide by their thermal treatment. With increasing temperature, the spinel composition changed according to the formula Mn1+xCr2–xO4 (0 ≤ x ≤ 1), where x = 0.7 at 500 °C and x = 1 at 900 °C when tet[MnII]oct[MnIIICrIII]O4 is formed. The (micro)structure, morphology, and optical properties of spinel Mn2CrO4 were characterized by PXRD, scanning electron microscopy and UV-Vis diffuse reflectance spectroscopy. The photocatalytic activity of this oxide in degradation of the methylene blue dye under Vis irradiation without and with the support of hydrogen peroxide was further investigated. author: - first_name: Ana full_name: Lozančić, Ana last_name: Lozančić - first_name: Sanja full_name: Burazer, Sanja last_name: Burazer - first_name: Tobias full_name: Wagner, Tobias last_name: Wagner - first_name: Krešimir full_name: Molčanov, Krešimir last_name: Molčanov - first_name: Damir full_name: Pajić, Damir last_name: Pajić - first_name: Lidija full_name: Androš Dubraja, Lidija last_name: Androš Dubraja - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Marijana full_name: Jurić, Marijana last_name: Jurić citation: ama: 'Lozančić A, Burazer S, Wagner T, et al.

In gas sensing, optical sensors are often used to detect gases such as CO, NOx, and O2. Oxygen sensors typically incorporate dyes into oxygen-permeable matrices like polymers, silica, or zeolites. Alternatively, semiconductor surface chemistry can enable O2 detection. However, these approaches are often limited by slow response and recovery times and low selectivity, restricting their practical applications. The metal-organic framework MOF-76(Eu) and its yttrium-modified variant, MOF-76(Eu/Y) are reported to exhibit highly reversible and fast optical responses to varying O2 concentrations. Time-resolved emission measurements are performed over short (seconds) and long (hours) timescales using N2 and synthetic air mixtures. Cross-sensitivity to humidity is analyzed. Multichannel scaling photon-counting experiments confirm quenching at the linker level, as the emission lifetime remains nearly constant. Yttrium significantly improves stability and performance at room temperature. Structural and optical changes induced by yttrium are investigated. Additionally, MIL-78(Eu), another Eu-BTC-based MOF with a different coordination environment, is synthesized. Unlike MOF-76(Eu), MIL-78(Eu) exhibits distinct optical properties but lacks a reversible response to O2. These results highlight the potential of MOF-76-based materials for high-performance O2 sensing. article_number: e11190 author: - first_name: Zhenyu full_name: Zhao, Zhenyu last_name: Zhao - first_name: Christian full_name: Weinberger, Christian id: '11848' last_name: Weinberger - first_name: Jakob full_name: Steube, Jakob id: '40342' last_name: Steube orcid: 0000-0003-3178-4429 - first_name: Matthias full_name: Bauer, Matthias id: '47241' last_name: Bauer orcid: 0000-0002-9294-6076 - first_name: Martin full_name: Brehm, Martin id: '100167' last_name: Brehm - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 citation: ama: Zhao Z, Weinberger C, Steube J, Bauer M, Brehm M, Tiemann M.

The progressive etching of the PLA film in direct contact with the nitrogen plasma was monitored in situ using polarization modulated infrared reflection absorption spectroscopy (PM‐IRRAS). No appreciative changes in composition were seen with PM‐IRRAS, indicating that the etching did not significantly affect the bulk composition. Atomic force microscopy characterization of the plasma‐etched films showed that the PLA films are homogeneously etched. Subsequent ex situ XPS analysis of the treated surface revealed the presence of C‐N bonds in the surface‐near region that could be associated with amino and/or amide surface species. PLA films were also alternatively exposed to nitrogen ion beams produced by an electron‐cyclotron‐resonance (ECR) plasma source and were investigated in vacuo by XPS. This treatment revealed the partial substitution of surface oxygen species by nitrogen, resulting in a similar surface modification as in the plasma case. The comparison of XPS data and water contact angle studies suggest that the activated surfaces show a reorientation of macromolecular fragments in the surface‐near region depending on the polarity of the phase with which they are in contact. Under ultra‐high vacuum (UHV) conditions, the surface tends to lower its surface energy, while in contact with the aqueous phase, subsurface polar groups orientate outwards, which enables the formation of hydrogen bonds." author: - first_name: Sandra full_name: Gołębiowska, Sandra last_name: Gołębiowska - first_name: Markus full_name: Voigt, Markus last_name: Voigt - first_name: Maria Teresa full_name: de los Arcos de Pedro, Maria Teresa id: '54556' last_name: de los Arcos de Pedro orcid: '0000-0002-8684-273X ' - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier citation: ama: Gołębiowska S, Voigt M, de los Arcos de Pedro MT, Grundmeier G.
