In this work, a cutting-edge nano-lithography-based method to control the local orientation of a thermotropic liquid crystal is applied to easily available commercial standard materials and evaluated. Parallel nanogrooves on a substrate, created through 3D nanoprinting in a negative-tone photoresin optimized for two-photon polymerization are used for this purpose. Azimuthal anchoring energies of the order from 10−6 J/m2 to 10−5 J/m2 are found, depending on the spacing, width and depth of the grooves. In part, these values are larger than those reported previously for another photopolymer. Both uniform alignment and spatial patterns of different alignment directions can be realized. Electro-optic studies confirm the suitability of the method for electrically addressable photonic applications and indicate strong polar anchoring."}],"citation":{"ieee":"B. Zhang, M. Plidschun, M.

Although these materials have been widely studied for a variety of applications, the mechanisms underlying the pyrolysis are yet poorly understood. This study provides a comprehensive temperature-resolved characterization of the chemical composition, morphology and crystallinity of sucrose-derived hydrochar during pyrolysis. Thermogravimetric analysis, differential scanning calorimetry, and elemental analysis have shown that the dry hydrochar loses about 41% of its dry mass due to the exothermic disintegration of oxygen-containing groups until the carbonization is completed at about 850 °C with a total carbon yield of 93%. The carbonization and aromatization of the initially furanic and keto-aliphatic structure were analyzed by 13C solid-state nuclear magnetic resonance spectroscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. The transition from an amorphous to a nanocrystalline graphitic structure was analyzed using X-ray diffraction and Raman spectroscopy. The pore formation mechanism was examined by helium ion microscopy, transmission electron microscopy, and nitrogen adsorption measurements. The results indicate the formation of oxygen-rich nanoclusters up to 700 °C, which decompose up to 750 °C leaving behind equally sized pores, resulting in a surface area of up to 480 m2/g.","lang":"eng"}],"article_type":"original","user_id":"23547","publication":"Journal of Analytical and Applied Pyrolysis","keyword":["Analytical Chemistry","Fuel Technology"],"publisher":"Elsevier BV","author":[{"last_name":"Wortmann","full_name":"Wortmann, Martin","first_name":"Martin"},{"full_name":"Keil, Waldemar","first_name":"Waldemar","last_name":"Keil"},{"first_name":"Bennet","full_name":"Brockhagen, Bennet","last_name":"Brockhagen"},{"first_name":"Jan","full_name":"Biedinger, Jan","last_name":"Biedinger"},{"full_name":"Westphal, Michael","first_name":"Michael","last_name":"Westphal"},{"last_name":"Weinberger","id":"11848","first_name":"Christian","full_name":"Weinberger, Christian"},{"full_name":"Diestelhorst, Elise","first_name":"Elise","last_name":"Diestelhorst"},{"first_name":"Wiebke","full_name":"Hachmann, Wiebke","last_name":"Hachmann"},{"last_name":"Zhao","full_name":"Zhao, Yanjing","first_name":"Yanjing"},{"first_name":"Michael","full_name":"Tiemann, Michael","orcid":"0000-0003-1711-2722","last_name":"Tiemann","id":"23547"},{"full_name":"Reiss, Günter","first_name":"Günter","last_name":"Reiss"},{"full_name":"Hüsgen, Bruno","first_name":"Bruno","last_name":"Hüsgen"},{"first_name":"Claudia","full_name":"Schmidt, Claudia","orcid":"0000-0003-3179-9997","last_name":"Schmidt","id":"466"},{"last_name":"Sattler","full_name":"Sattler, Klaus","first_name":"Klaus"},{"last_name":"Frese","full_name":"Frese, Natalie","first_name":"Natalie"}],"quality_controlled":"1","date_created":"2022-01-18T06:25:06Z","status":"public","volume":161,"date_updated":"2023-03-08T08:15:24Z","doi":"10.1016/j.jaap.2021.105404","language":[{"iso":"eng"}],"title":"Pyrolysis of sucrose-derived hydrochar","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"},{"_id":"315"}],"publication_status":"published","publication_identifier":{"issn":["0165-2370"]}},{"publication_identifier":{"issn":["1525-7797","1526-4602"]},"volume":22,"publication_status":"published","date_created":"2021-10-11T07:31:04Z","status":"public","publication":"Biomacromolecules","department":[{"_id":"302"},{"_id":"314"},{"_id":"387"}],"author":[{"last_name":"Hense","full_name":"Hense, Dominik","first_name":"Dominik"},{"first_name":"Anne","full_name":"Büngeler, Anne","last_name":"Büngeler"},{"full_name":"Kollmann, Fabian","first_name":"Fabian","last_name":"Kollmann"},{"last_name":"Hanke","full_name":"Hanke, Marcel","first_name":"Marcel"},{"full_name":"Orive, Alejandro","first_name":"Alejandro","last_name":"Orive"},{"first_name":"Adrian","full_name":"Keller, Adrian","orcid":"0000-0001-7139-3110","last_name":"Keller","id":"48864"},{"first_name":"Guido","full_name":"Grundmeier, Guido","last_name":"Grundmeier","id":"194"},{"full_name":"Huber, Klaus","first_name":"Klaus","last_name":"Huber"},{"full_name":"Strube, Oliver I.","first_name":"Oliver I.","last_name":"Strube"}],"title":"Self-Assembled Fibrinogen Hydro- and Aerogels with Fibrin-like 3D Structures","user_id":"48864","page":"4084–4094","type":"journal_article","year":"2021","citation":{"ieee":"D.

It was revealed via electrochemical measurements that one oxidation and two reductions take place. The bandgaps determined via the electrochemical approach are in good agreement with the optical bandgap obtained from the absorption spectra via a Tauc plot. In addition, absorption spectra in dependence of the electrochemical potential were the basis for extensive quantum-chemical calculations of the neutral, monoanionic, and dianionic molecules. For this purpose, calculations based on density functional theory were compared with post-Hartree–Fock methods and the CAM-B3LYP functional proved to be the most reliable choice for the calculation of absorption spectra. Furthermore, spectral features found experimentally could be reproduced with vibronic calculations and allowed to understand their origins. In particular, the two lowest energy absorption bands of the anion are not caused by absorption of two distinct electronic states, which might have been expected from vertical excitation calculations, but both states exhibit a strong vibronic progression resulting in contributions to both bands.","lang":"eng"}],"user_id":"16199"},{"title":"The Deterioration Mechanism of Silicone Molds in Polyurethane Vacuum Casting","publication_identifier":{"issn":["2637-6105","2637-6105"]},"publication_status":"published","department":[{"_id":"2"},{"_id":"315"},{"_id":"232"}],"doi":"10.1021/acsapm.0c00744","date_updated":"2023-01-07T10:28:55Z","language":[{"iso":"eng"}],"user_id":"466","article_type":"original","status":"public","date_created":"2023-01-06T12:36:56Z","volume":2,"publisher":"American Chemical Society (ACS)","author":[{"last_name":"Wortmann","full_name":"Wortmann, Martin","first_name":"Martin"},{"full_name":"Frese, Natalie","first_name":"Natalie","last_name":"Frese"},{"first_name":"Waldemar","full_name":"Keil, Waldemar","last_name":"Keil"},{"first_name":"Johannes","full_name":"Brikmann, Johannes","last_name":"Brikmann"},{"last_name":"Biedinger","first_name":"Jan","full_name":"Biedinger, Jan"},{"last_name":"Brockhagen","full_name":"Brockhagen, Bennet","first_name":"Bennet"},{"last_name":"Reiss","full_name":"Reiss, Günter","first_name":"Günter"},{"id":"466","last_name":"Schmidt","full_name":"Schmidt, Claudia","orcid":"0000-0003-3179-9997","first_name":"Claudia"},{"last_name":"Gölzhäuser","full_name":"Gölzhäuser, Armin","first_name":"Armin"},{"full_name":"Moritzer, Elmar","first_name":"Elmar","id":"20531","last_name":"Moritzer"},{"first_name":"Bruno","full_name":"Hüsgen, Bruno","last_name":"Hüsgen"}],"quality_controlled":"1","keyword":["Organic Chemistry","Polymers and Plastics","Process Chemistry and Technology"],"publication":"ACS Applied Polymer Materials","issue":"11","_id":"35328","intvolume":" 2","type":"journal_article","year":"2020","citation":{"short":"M.

The respective liquid crystalline nanodispersions are doped with a dichroic fluorescent dye and their orientational order parameter is studied by means of polarized fluorescence spectroscopy. The presence of the nano-particles is found to slightly reduce the orientational order parameter of the nematic mesophase. Nano-rods with a large length/width ratio tend to preserve the orientational order, while more compact stiff nano-rods and especially nano-sheets reduce the order parameter to a larger extent.

Depending on the concentration of polymer and Ca2+ and on the ratio of the block lengths in the copolymer, spherical micelles were observed. Micelle formation arises from the specific interaction of Ca2+ with the PA block only. An extensive small-angle scattering study was performed in order to unravel the structure and dimensions of the block copolymer micelles. Deuteration of the PA block enabled us to perform contrast variation experiments using small-angle neutron scattering at variable ratios of light and heavy water which were combined with information from small-angle X-ray scattering and dynamic light scattering.","lang":"eng"}],"user_id":"237","page":"663-679","year":"2020","type":"journal_article","citation":{"chicago":"Carl, Nico, Sylvain Prévost, Ralf Schweins, and Klaus Huber. “Contrast Variation of Micelles Composed of Ca2+ and Block Copolymers of Two Negatively Charged Polyelectrolytes.” Colloid and Polymer Science 298, no. 7 (2020): 663–79. https://doi.org/10.1007/s00396-019-04596-1.","apa":"Carl, N., Prévost, S., Schweins, R., & Huber, K.
