By the strict control of temperature and Pd/Au molar ratio and the use of l-ascorbic acid for making both Au cores and Pd shells, a 1.5 nm Pd layer is formed around the Au core, as evidenced by transmission electron microscopy and energy-dispersive spectroscopy. The core@shell structure and the Pd shell remain intact upon deposition onto alumina and after being used for CO oxidation, as revealed by additional X-ray diffraction and X-ray photoemission spectroscopy before and after the reaction. The Pd shell surface was characterized with in situ infrared (IR) spectroscopy using CO as a chemical probe during CO adsorption–desorption. The IR bands for CO ad-species on the Pd shell suggest that the shell exposes mostly low-index surfaces, likely Pd(111) as the majority facet. Generally, the IR bands are blue-shifted as compared to conventional Pd/alumina catalysts, which may be due to the different support materials for Pd, Au versus Al2O3, and/or less strain of the Pd shell. Frequencies obtained from density functional calculations suggest the latter to be significant. Further, the catalytic CO oxidation ignition-extinction processes were followed by in situ IR, which shows the common CO poisoning and kinetic behavior associated with competitive adsorption of CO and O2 that is typically observed for noble metal catalysts.}}, author = {{Feng, Yanyue and Schaefer, Andreas and Hellman, Anders and Di, Mengqiao and Härelind, Hanna and Bauer, Matthias and Carlsson, Per-Anders}}, issn = {{0743-7463}}, journal = {{Langmuir}}, keywords = {{Electrochemistry, Spectroscopy, Surfaces and Interfaces, Condensed Matter Physics, General Materials Science}}, number = {{42}}, pages = {{12859--12870}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Synthesis and Characterization of Catalytically Active Au Core─Pd Shell Nanoparticles Supported on Alumina}}}, doi = {{10.1021/acs.langmuir.2c01834}}, volume = {{38}}, year = {{2022}}, } @article{23608, author = {{Prihoda, Annemarie and Will, Johannes and Duchstein, Patrick and Becit, Bahanur and Lossin, Felix and Schindler, Torben and Berlinghof, Marvin and Steinrück, Hans-Georg and Bertram, Florian and Zahn, Dirk and Unruh, Tobias}}, issn = {{0743-7463}}, journal = {{Langmuir}}, pages = {{12077--12086}}, title = {{{Interface between Water–Solvent Mixtures and a Hydrophobic Surface}}}, doi = {{10.1021/acs.langmuir.0c02745}}, volume = {{36}}, year = {{2020}}, } @article{22534, author = {{Schwiderek, Sabrina and Orive, Alejandro G. and Karimi Aghda, Soheil and Schneider, Jochen M. and de los Arcos de Pedro, Maria Teresa and Grundmeier, Guido}}, issn = {{0743-7463}}, journal = {{Langmuir}}, pages = {{9489--9498}}, title = {{{Single-Molecule Desorption Studies of Poly(acrylic acid) at Electrolyte/Oxide/TiAlN Interfaces}}}, doi = {{10.1021/acs.langmuir.0c00188}}, year = {{2020}}, } @article{19193, author = {{Niederhausen, Jens and MacQueen, Rowan W. and Lips, Klaus and Aldahhak, Hazem and Schmidt, Wolf Gero and Gerstmann, Uwe}}, issn = {{0743-7463}}, journal = {{Langmuir}}, pages = {{9099--9113}}, title = {{{Tetracene Ultrathin Film Growth on Hydrogen-Passivated Silicon}}}, doi = {{10.1021/acs.langmuir.0c01154}}, year = {{2020}}, } @article{22652, author = {{Hämisch, Benjamin and Büngeler, Anne and Kielar, Charlotte and Keller, Adrian and Strube, Oliver and Huber, Klaus}}, issn = {{0743-7463}}, journal = {{Langmuir}}, pages = {{12113--12122}}, title = {{{Self-Assembly of Fibrinogen in Aqueous, Thrombin-Free Solutions of Variable Ionic Strengths}}}, doi = {{10.1021/acs.langmuir.9b01515}}, volume = {{35}}, year = {{2019}}, } @article{41822, author = {{Carl, Nico and Müller, Wenke and Schweins, Ralf and Huber, Klaus}}, issn = {{0743-7463}}, journal = {{Langmuir}}, keywords = {{Electrochemistry, Spectroscopy, Surfaces and Interfaces, Condensed Matter Physics, General Materials Science}}, number = {{1}}, pages = {{223--231}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Controlling Self-Assembly with Light and Temperature}}}, doi = {{10.1021/acs.langmuir.9b03040}}, volume = {{36}}, year = {{2019}}, } @article{41828, author = {{Hämisch, Benjamin and Büngeler, Anne and Kielar, Charlotte and Keller, Adrian and Strube, Oliver and Huber, Klaus}}, issn = {{0743-7463}}, journal = {{Langmuir}}, keywords = {{Electrochemistry, Spectroscopy, Surfaces and Interfaces, Condensed Matter Physics, General Materials Science}}, number = {{37}}, pages = {{12113--12122}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Self-Assembly of Fibrinogen in Aqueous, Thrombin-Free Solutions of Variable Ionic Strengths}}}, doi = {{10.1021/acs.langmuir.9b01515}}, volume = {{35}}, year = {{2019}}, } @article{25305, author = {{Rüdiger, Arne A. and Brassat, Katharina and Lindner, Jörg K.

Here, we investigate the adsorption of DNA origami nanostructures in nanohole arrays which represent an important class of biosensors and may benefit from the incorporation of DNA origami-based molecular probes. Nanoholes with well-defined diameter that enable the adsorption of single DNA origami triangles are fabricated in Au films on Siwafers by nanosphere lithography. The efficiency of directed DNA origami adsorption on the exposed SiO2 areas at the bottoms of the nanoholes is evaluated in dependence of various parameters, i.e., Mg2+ and DNA origami concentrations, buffer strength, adsorption time, and nanohole diameter. We observe that the buffer strength has a surprisingly strong effect on DNA origami adsorption in the nanoholes and that multiple DNA origami triangles with 120 nm edge length can adsorb in nanoholes as small as 120 nm in diameter. We attribute the latter observation to the low lateral mobility of once adsorbed DNA origami on the SiO2 surface, in combination with parasitic adsorption to the Au film. While parasitic adsorption can be suppressed by modifying the Au film with a hydrophobic self-assembled monolayer, the limited surface mobility of the adsorbed DNA origami still leads to poor localization accuracy in the nanoholes and results in many DNA origami crossing the boundary to the Au film even under optimized conditions. We discuss possible ways to minimize this effect by varying the composition of the adsorption buffer, employing different fabrication conditions, or using other substrate materials for nanohole array fabrication.}}, author = {{Brassat, Katharina and Ramakrishnan, Saminathan and Bürger, Julius and Hanke, Marcel and Doostdar, Mahnaz and Lindner, Jörg and Grundmeier, Guido and Keller, Adrian}}, issn = {{0743-7463}}, journal = {{Langmuir}}, publisher = {{American Chemical Society (ACS)}}, title = {{{On the Adsorption of DNA Origami Nanostructures in Nanohole Arrays}}}, doi = {{10.1021/acs.langmuir.8b00793}}, year = {{2018}}, } @article{22664, author = {{Brassat, Katharina and Ramakrishnan, Saminathan and Bürger, Julius and Hanke, Marcel and Doostdar, Mahnaz and Lindner, Jörg and Grundmeier, Guido and Keller, Adrian}}, issn = {{0743-7463}}, journal = {{Langmuir}}, pages = {{14757--14765}}, title = {{{On the Adsorption of DNA Origami Nanostructures in Nanohole Arrays}}}, doi = {{10.1021/acs.langmuir.8b00793}}, volume = {{34}}, year = {{2018}}, } @article{22667, author = {{Hajiraissi, Roozbeh and Hanke, Marcel and Yang, Yu and Duderija, Belma and Gonzalez Orive, Alejandro and Grundmeier, Guido and Keller, Adrian}}, issn = {{0743-7463}}, journal = {{Langmuir}}, pages = {{3517--3524}}, title = {{{Adsorption and Fibrillization of Islet Amyloid Polypeptide at Self-Assembled Monolayers Studied by QCM-D, AFM, and PM-IRRAS}}}, doi = {{10.1021/acs.langmuir.7b03626}}, volume = {{34}}, year = {{2018}}, } @article{5971, author = {{Kuczera, Stefan and Gentile, Luigi and Brox, Timothy I. and Olsson, Ulf and Schmidt, Claudia and Galvosas, Petrik}}, issn = {{0743-7463}}, journal = {{Langmuir}}, number = {{28}}, pages = {{8314--8325}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Multilamellar Vesicle Formation Probed by Rheo-NMR and Rheo-SALS under Large Amplitude Oscillatory Shear}}}, doi = {{10.1021/acs.langmuir.8b01510}}, volume = {{34}}, year = {{2018}}, } @article{3925, abstract = {{Site-specific formation of nanoscaled protein structures is a challenging task. Most known structuring methods are either complex and hardly upscalable or do not apply to biological matter at all. The presented combination of enzyme mediated autodeposition and nanosphere lithography provides an easy-to-apply approach for the buildup of protein nanostructures over a large scale. The key factor is the tethering of enzyme to the support in designated areas. Those areas are provided via prepatterning of enzymatically active antidots with variable diameters. Enzymatically triggered protein addressing occurs exclusively at the intended areas and continues until the entire active area is coated. After this, the reaction self-terminates. The major advantage of the presented method lies in its easy applicability and upscalability. Large area structuring of entire support surfaces with features on the nanometer scale is performed efficiently and without the necessity of harsh conditions. These are valuable premises for large-scale applications with potentials in biosensor technology, nanoelectronics, and life sciences.}}, author = {{Rüdiger, Arne A. and Brassat, Katharina and Lindner, Jörg and Bremser, Wolfgang and Strube, Oliver I.}}, issn = {{0743-7463}}, journal = {{Langmuir}}, number = {{14}}, pages = {{4264--4270}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Easily Accessible Protein Nanostructures via Enzyme Mediated Addressing}}}, doi = {{10.1021/acs.langmuir.7b04089}}, volume = {{34}}, year = {{2018}}, } @article{41830, author = {{Stolzenburg, Pierre and Hämisch, Benjamin and Richter, Sebastian and Huber, Klaus and Garnweitner, Georg}}, issn = {{0743-7463}}, journal = {{Langmuir}}, keywords = {{Electrochemistry, Spectroscopy, Surfaces and Interfaces, Condensed Matter Physics, General Materials Science}}, number = {{43}}, pages = {{12834--12844}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Secondary Particle Formation during the Nonaqueous Synthesis of Metal Oxide Nanocrystals}}}, doi = {{10.1021/acs.langmuir.8b00020}}, volume = {{34}}, year = {{2018}}, } @article{25306, author = {{Büngeler, Anne and Hämisch, Benjamin and Huber, Klaus and Bremser, Wolfgang and Strube, Oliver I.}}, issn = {{0743-7463}}, journal = {{Langmuir}}, pages = {{6895--6901}}, title = {{{Insight into the Final Step of the Supramolecular Buildup of Eumelanin}}}, doi = {{10.1021/acs.langmuir.7b01634}}, year = {{2017}}, } @article{41836, author = {{Kley, M. and Kempter, A. and Boyko, V. and Huber, Klaus}}, issn = {{0743-7463}}, journal = {{Langmuir}}, keywords = {{Electrochemistry, Spectroscopy, Surfaces and Interfaces, Condensed Matter Physics, General Materials Science}}, number = {{24}}, pages = {{6071--6083}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Silica Polymerization from Supersaturated Dilute Aqueous Solutions in the Presence of Alkaline Earth Salts}}}, doi = {{10.1021/acs.langmuir.7b00887}}, volume = {{33}}, year = {{2017}}, }
