However, silicon oxide surfaces come in many different forms and the type and history of the silicon oxide has a large effect on its physicochemical surface properties. Therefore, we here investigate DNA origami lattice formation on differently fabricated SiOx films on silicon wafers after wet-chemical oxidation by RCA1. Despite having similar oxide compositions and hydroxylation states, of all surfaces tested, only thermally grown SiOx performs similarly well as native oxide. For the other SiOx films deposited by plasma-enhanced chemical vapor deposition and magnetron sputtering, DNA origami adsorption is strongly suppressed. This is attributed to an increased surface roughness and a lower oxide density, respectively. Our results demonstrate that the employed SiOx surface may decide over the outcome of an experiment and should be considered as an additional parameter that may require optimization and fine-tuning before high-quality lattices can be assembled. In particular, our observations suggest that efficient DNA origami lattice assembly on SiOx surfaces requires a low surface roughness and a high oxide density."}],"date_created":"2025-02-12T14:49:48Z","type":"journal_article","department":[{"_id":"302"}]},{"title":"DNA origami nanostructures in biomedicine and the issue of stability","year":"2025","author":[{"id":"48864","last_name":"Keller","first_name":"Adrian","orcid":"0000-0001-7139-3110","full_name":"Keller, Adrian"}],"date_updated":"2025-06-10T09:09:28Z","intvolume":" 2","language":[{"iso":"eng"}],"doi":"10.18609/nuc.2025.011","publication":"Nucleic Acid Insights","issue":"2","file":[{"date_created":"2025-06-01T08:53:35Z","creator":"adke","file_id":"60083","content_type":"application/pdf","file_name":"Keller_nai25.pdf","file_size":701125,"access_level":"open_access","relation":"main_file","date_updated":"2025-06-01T08:53:35Z"}],"date_created":"2025-06-01T08:53:58Z","type":"journal_article","department":[{"_id":"302"}],"status":"public","has_accepted_license":"1","page":"61–75","_id":"60082","user_id":"48864","ddc":["570"],"volume":2,"file_date_updated":"2025-06-01T08:53:35Z","citation":{"mla":"Keller, Adrian. “DNA Origami Nanostructures in Biomedicine and the Issue of Stability.” Nucleic Acid Insights, vol. 2, no. 2, 2025, pp. 61–75, doi:10.18609/nuc.2025.011.","bibtex":"@article{Keller_2025, title={DNA origami nanostructures in biomedicine and the issue of stability}, volume={2}, DOI={10.18609/nuc.2025.011}, number={2}, journal={Nucleic Acid Insights}, author={Keller, Adrian}, year={2025}, pages={61–75} }","ama":"Keller A.

Both datasets were evaluated with simple equivalent circuits and comparatively analyzed. Conductivity of the electrolyte was independently measured. Cyclic voltammograms (CV) show larger resistance and capacitance at low scan rates. Resistances obtained from EIS are in good agreement with those obtained by cyclic voltammograms particularly at high scan rates. The comparison against specific electrolyte resistance can reveal whether resistances within the solid electrode architecture or resistances within the electrolyte, partially confined by pores, are the dominant cause of increased resistance at low scan rate. Comparison between CV and EIS points to the main electrode capacitance being described by a constant phase element (CPE) used to fit the low-frequency region of EIS."}],"quality_controlled":"1","language":[{"iso":"eng"}],"_id":"62814","publisher":"IEEE","user_id":"116779","doi":"10.1109/iwis63047.2024.10847115","title":"Complementary Analysis of Cyclic Voltammograms and Impedance Spectra of Porous Carbon Electrodes","status":"public","year":"2025","author":[{"full_name":"Reinke, Sebastian","first_name":"Sebastian","last_name":"Reinke","id":"117727"},{"first_name":"Vera","last_name":"Khamitsevich","full_name":"Khamitsevich, Vera"},{"id":"116779","orcid":"0000-0001-6883-5424","last_name":"Linnemann","first_name":"Julia","full_name":"Linnemann, Julia"}],"publication_status":"published","date_updated":"2026-01-19T15:41:43Z"},{"date_created":"2026-02-09T09:03:41Z","department":[{"_id":"27"},{"_id":"2"}],"type":"preprint","citation":{"chicago":"Wu, Xin, Hossam Elgabarty, Vahideh Alizadeh, Andres Henao Aristizabal, Frederik Zysk, Christian Plessl, Sebastian Ehlert, Jürg Hutter, and Thomas D.

Besides the original parameter sets, some specifically reparametrized SQC methods (denoted as AM1-W, PM6-fm, and DFTB2-iBi) targeting various smaller water systems ranging from molecular clusters to bulk are considered as well. The quality of these different SQC methods for describing liquid water properties at ambient conditions are assessed by comparison to well-established experimental data and also to BLYP-D3 density functional theory-based ab initio MD simulations. Our analyses reveal that static and dynamics properties of bulk water are poorly described by all considered SQC methods with the original parameters, regardless of the underlying theoretical models, with most of the methods suffering from too weak hydrogen bonds and hence predicting a far too fluid water with highly distorted hydrogen bond kinetics. On the other hand, the reparametrized force-matchcd PM6-fm method is shown to be able to quantitatively reproduce the static and dynamic features of liquid water, and thus can be used as a computationally efficient alternative to electronic structure-based MD simulations for liquid water that requires extended length and time scales. DFTB2-iBi predicts a slightly overstructured water with reduced fluidity, whereas AM1-W gives an amorphous ice-like structure for water at ambient conditions.","lang":"eng"}],"_id":"64071","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://arxiv.org/abs/2503.11867"}],"user_id":"77439","author":[{"full_name":"Wu, Xin","last_name":"Wu","first_name":"Xin","id":"77439"},{"orcid":"0000-0002-4945-1481","first_name":"Hossam","last_name":"Elgabarty","full_name":"Elgabarty, Hossam","id":"60250"},{"first_name":"Vahideh","last_name":"Alizadeh","full_name":"Alizadeh, Vahideh"},{"id":"67235","full_name":"Henao Aristizabal, Andres","last_name":"Henao Aristizabal","first_name":"Andres"},{"first_name":"Frederik","last_name":"Zysk","full_name":"Zysk, Frederik","id":"14757"},{"full_name":"Plessl, Christian","orcid":"0000-0001-5728-9982","first_name":"Christian","last_name":"Plessl","id":"16153"},{"full_name":"Ehlert, Sebastian","first_name":"Sebastian","last_name":"Ehlert"},{"last_name":"Hutter","first_name":"Jürg","full_name":"Hutter, Jürg"},{"id":"49079","first_name":"Thomas D.","last_name":"Kühne","full_name":"Kühne, Thomas D."}],"year":"2025","status":"public","title":"Benchmarking semi-empirical quantum chemical methods on liquid water","date_updated":"2026-02-09T09:17:07Z"},{"abstract":[{"text":"AbstractControlling the surface orientation of DNA origami nanostructures (DON) is crucial for applications in nanotechnology and materials science.

Herein, a novel protocol is reported for the synthesis of amidines based on PIII/PVO redox catalysis. This two‐step, one‐pot approach involves the activation of amides via PIII/PVO 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.","lang":"eng"}],"publication":"Advanced Synthesis and Catalysis","citation":{"short":"V.

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","_id":"62190","publisher":"Wiley","language":[{"iso":"eng"}],"doi":"10.1002/ppsc.202500085","user_id":"237","status":"public","year":"2025","title":"Static Light Scattering for Lignin Particle Size Characterization","publication_identifier":{"issn":["0934-0866","1521-4117"]},"author":[{"full_name":"Makkonen, Janita","last_name":"Makkonen","first_name":"Janita"},{"full_name":"Ahvenainen, Patrik","first_name":"Patrik","last_name":"Ahvenainen"},{"full_name":"Bertella, Stefania","last_name":"Bertella","first_name":"Stefania"},{"full_name":"Kellock, Miriam","first_name":"Miriam","last_name":"Kellock"},{"full_name":"Saha, Sanjib","last_name":"Saha","first_name":"Sanjib"},{"full_name":"Huber, Klaus","first_name":"Klaus","last_name":"Huber","id":"237"},{"full_name":"Farooq, Muhammad","first_name":"Muhammad","last_name":"Farooq"},{"last_name":"Österberg","first_name":"Monika","full_name":"Österberg, Monika"},{"full_name":"Penttilä, Paavo","last_name":"Penttilä","first_name":"Paavo"}],"date_updated":"2025-11-18T16:29:53Z","publication_status":"published"},{"citation":{"mla":"Koch, Leon, et al. “Self-Assembly of Pseudo Isocyanine Chloride in the Presence of Attractive Polyethylene Glycol Crowders.” The Journal of Physical Chemistry B, vol. 129, no. 25, American Chemical Society (ACS), 2025, pp. 6115–26, doi:10.1021/acs.jpcb.4c06843.","bibtex":"@article{Koch_Rajput_Richter_König_Nayar_Ebbinghaus_Huber_2025, title={Self-Assembly of Pseudo Isocyanine Chloride in the Presence of Attractive Polyethylene Glycol Crowders}, volume={129}, DOI={10.1021/acs.jpcb.4c06843}, number={25}, journal={The Journal of Physical Chemistry B}, publisher={American Chemical Society (ACS)}, author={Koch, Leon and Rajput, Satyendra and Richter, Antonio and König, Benedikt and Nayar, Divya and Ebbinghaus, Simon and Huber, Klaus}, year={2025}, pages={6115–6126} }","ama":"Koch L, Rajput S, Richter A, 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.","lang":"eng"}],"publication":"ACS Applied Materials & Interfaces","issue":"29","volume":17,"user_id":"116779","_id":"62798","publisher":"American Chemical Society (ACS)","page":"41893-41903","status":"public","oa":"1","quality_controlled":"1","citation":{"apa":"Hiege, F., Chang, C.-W., Trost, O., van Halteren, C.

The isostructural heterometallic complex salts were characterized by single-crystal and powder X-ray diffraction, infrared and impedance spectroscopy, thermal analysis and magnetization measurements. The trinuclear anion [{Mn(bpy)(H2O)Cl(μ-C2O4)}2Cr(C2O4)]− consists of two [Mn(bpy)(H2O)Cl]+ units bridged by the [Cr(C2O4)3]3− anion, which acts as a bidentate ligand towards each of the manganese atoms. The anions are hydrogen bonded to each other via coordinated chloride anions, water molecules and oxygen oxalate atoms, resulting in two-dimensional (2D) hydrogen bonding layers. Compounds exhibit water-assisted proton conductivity behaviour, which was investigated at different temperatures and relative humidities (RH). 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.","lang":"eng"}],"issue":"41","publication":"Journal of Materials Chemistry C"},{"type":"journal_article","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"date_created":"2025-12-03T17:09:28Z","abstract":[{"lang":"eng","text":"The increasing demand for advanced sensing technologies drives the development of chemical sensors using innovative materials. 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."}],"publication":"Advanced Functional Materials","doi":"10.1002/adfm.202511190","main_file_link":[{"open_access":"1"}],"article_number":"e11190","language":[{"iso":"eng"}],"date_updated":"2025-12-03T17:11:15Z","publication_status":"published","year":"2025","title":"Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)","publication_identifier":{"issn":["1616-301X","1616-3028"]},"author":[{"full_name":"Zhao, Zhenyu","first_name":"Zhenyu","last_name":"Zhao"},{"last_name":"Weinberger","first_name":"Christian","full_name":"Weinberger, Christian","id":"11848"},{"first_name":"Jakob","last_name":"Steube","orcid":"0000-0003-3178-4429","full_name":"Steube, Jakob","id":"40342"},{"id":"47241","full_name":"Bauer, Matthias","first_name":"Matthias","orcid":"0000-0002-9294-6076","last_name":"Bauer"},{"full_name":"Brehm, Martin","last_name":"Brehm","first_name":"Martin","id":"100167"},{"id":"23547","full_name":"Tiemann, Michael","orcid":"0000-0003-1711-2722","first_name":"Michael","last_name":"Tiemann"}],"oa":"1","quality_controlled":"1","citation":{"mla":"Zhao, Zhenyu, et al. “Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76).” Advanced Functional Materials, e11190, Wiley, 2025, doi:10.1002/adfm.202511190.","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."}],"issue":"7","publication":"Surface and Interface Analysis","doi":"10.1002/sia.7406","language":[{"iso":"eng"}],"date_updated":"2025-12-04T13:13:00Z","publication_status":"published","intvolume":" 57","year":"2025","title":"In Situ PM‐IRRAS and XPS Analysis of Nitrogen Plasma Surface Modification of Polylactide Thin Films","publication_identifier":{"issn":["0142-2421","1096-9918"]},"author":[{"full_name":"Gołębiowska, Sandra","first_name":"Sandra","last_name":"Gołębiowska"},{"full_name":"Voigt, Markus","first_name":"Markus","last_name":"Voigt"},{"first_name":"Maria Teresa","orcid":"0000-0002-8684-273X ","last_name":"de los Arcos de Pedro","full_name":"de los Arcos de Pedro, Maria Teresa","id":"54556"},{"id":"194","full_name":"Grundmeier, Guido","last_name":"Grundmeier","first_name":"Guido"}]}]
