Unfortunately, studies investigating this alloy showed that additively produced samples exhibit anisotropic microstructures. This anisotropy compromises the mechanical properties and complicates the loading state in the implant. Moreover, the minimum requirements as specified per designated standards such as ISO 5832-11 are not met. The remedy to this problem is performing a conventional heat treatment. As this route requires energy, infrastructure, labor, and expertise, which in turn mean time and money, many of the additive manufacturing benefits are negated. Thus, the goal of this work was to achieve better isotropy by applying only adapted additive manufacturing process parameters, specifically focusing on the build orientations. In this work, samples orientated in 90°, 45°, and 0° directions relative to the building platform were manufactured and tested. These tests included mechanical (tensile and fatigue tests) as well as microstructural analyses (SEM and EBSD). Subsequently, the results of these tests such as fractography were correlated with the acquired mechanical properties. These showed that 90°-aligned samples performed best under fatigue load and that all requirements specified by the standard regarding monotonic load were met.</jats:p>","lang":"eng"}],"publication":"Crystals","language":[{"iso":"eng"}],"keyword":["Inorganic Chemistry","Condensed Matter Physics","General Materials Science","General Chemical Engineering"],"citation":{"apa":"Milaege, D., Eschemann, N., Hoyer, K.-P., &#38; Schaper, M.

The fabrication of low-loss optical waveguides, as well as high-grade periodically poled ferroelectric domain structures, requires a profound understanding of the material properties and crystal structure. In this regard, Raman spectroscopy offers the possibility to study and visualize domain structures, strain, defects, and the local stoichiometry, which are all factors impacting device performance. However, the accurate interpretation of Raman spectra and their changes with respect to extrinsic and intrinsic defects requires a thorough assignment of the Raman modes to their respective crystal features, which to date is only partly conducted based on phenomenological modelling. To address this issue, we calculated the phonon spectra of potassium titanyl phosphate and the related compounds rubidium titanyl phosphate (RbTiOPO4) and potassium titanyl arsenate (KTiOAsO4) based on density functional theory and compared them with experimental data. Overall, this allows us to assign various spectral features to eigenmodes of lattice substructures with improved detail compared to previous assignments. Nevertheless, the analysis also shows that not all features of the spectra can unambigiously be explained yet. A possible explanation might be that defects or long range fields not included in the modeling play a crucial rule for the resulting Raman spectrum. In conclusion, this work provides an improved foundation into the vibrational properties in the KTiOPO4 material family.","lang":"eng"}],"publication":"Crystals","language":[{"iso":"eng"}],"keyword":["Inorganic Chemistry","Condensed Matter Physics","General Materials Science","General Chemical Engineering"],"citation":{"apa":"Neufeld, S., Gerstmann, U., Padberg, L., Eigner, C., Berth, G., Silberhorn, C., Eng, L.

To mitigate the narrowing of coronary artery atherosclerosis (stenosis), the computational modelling of auxetic and non-auxetic stents was performed in this study to minimise or even avoid these deposition agents in the future. Computational modelling was performed in unrestricted (open) conditions and restricted (in an artery) conditions. Finally, stent designs were produced by additive manufacturing, and mechanical testing of the stents was undertaken. Auxetic stent 1 and auxetic stent 2 exhibit very little foreshortening and radial recoil in unrestricted deployment conditions compared to non-auxetic stent 3. However, stent 2 shows structural instability (strut failure) during unrestricted deployment conditions. For the restricted deployment condition, stent 1 shows a higher radial recoil compared to stent 3. In the tensile test simulations, short elongation for stent 1 due to strut failure is demonstrated, whereas no structural instability is noticed for stent 2 and stent 3 until 0.5 (mm/mm) strain. The as-built samples show a significant thickening of the struts of the stents resulting in short elongations during tensile testing compared to the simulations (stent 2 and stent 3). A modelling framework for the stent deployment system that enables the selection of appropriate stent designs before in vivo testing is required. This leads to the acceleration of the development process and a reduction in time, resulting in less material wastage.

In contrast to the numerous studies on chromium(III) photophysics, only 10 luminescent molybdenum(III) complexes have been reported so far. Here, we present the synthesis and characterization of mer-MoX3(ddpd) (1, X = Cl; 2, X = Br) and cisfac-[Mo(ddpd)2]3+ (cisfac-[3]3+), an isomeric heavy homologue of the prototypical molecular ruby. For cisfac-[3]3+, we found strong zero-field splitting using magnetic susceptibility measurements and electron paramagnetic resonance spectroscopy. Electronic spectra covering the spin-forbidden transitions show that the spin-flip states in mer-1, mer-2, and cisfac-[3]3+ are much lower in energy than those in comparable chromium(III) compounds. While all three complexes show weak spin-flip phosphorescence in NIR-II, the emission of cisfac-[3]3+ peaking at 1550 nm is particularly low in energy. Femtosecond transient absorption spectroscopy reveals a short excited-state lifetime of 1.4 ns, 6 orders of magnitude shorter than that of mer-[Cr(ddpd)2]3+. Using density functional theory and ab initio multireference calculations, we break down the reasons for this disparity and derive principles for the design of future stable photoactive molybdenum(III) complexes."}],"language":[{"iso":"eng"}],"keyword":["Inorganic Chemistry","Physical and Theoretical Chemistry"]},{"_id":"52344","department":[{"_id":"306"}],"user_id":"48467","keyword":["Inorganic Chemistry","Organic Chemistry","Physical and Theoretical Chemistry","Catalysis"],"article_type":"original","language":[{"iso":"eng"}],"publication":"ChemCatChem","type":"journal_article","abstract":[{"lang":"eng","text":"Macrocyclization reactions are still challenging due to competing oligomerization, which requires the use of small substrate concentrations.

Catalytic testing with four differently sized α,ω-dienes revealed a dramatically increased macrocyclization (MC) and Z-selectivity of the supported catalysts compared to the homogenous progenitors, allowing high substrate concentrations of 25 mM. With the supported complexes, a maximum increase in MC-selectivity from 27 to 81 % and in Z-selectivity from 17 to 34 % was achieved.

Herein, ferritin adsorption at flat and nanofaceted, single-crystalline Al2O3 surfaces is investigated using atomic force microscopy and X-ray photoelectron spectroscopy. The nanofaceted surfaces are generated by the thermal annealing of Al2O3 wafers at temperatures above 1000 °C, which leads to the formation of faceted saw-tooth-like surface topographies with periodicities of about 160 nm and amplitudes of about 15 nm. Ferritin adsorption at these nanofaceted surfaces is notably suppressed compared to the flat surface at a concentration of 10 mg/mL, which is attributed to lower adsorption affinities of the newly formed facets. Consequently, adsorption is restricted mostly to the pattern grooves, where the proteins can maximize their contact area with the surface. However, this effect depends on the protein concentration, with an inverse trend being observed at 30 mg/mL. Furthermore, different ferritin adsorption behavior is observed at topographically similar nanofacet patterns fabricated at different annealing temperatures and attributed to different step and kink densities. These results demonstrate that while protein adsorption at solid surfaces can be notably affected by nanofacet patterns, fine-tuning protein adsorption in this way requires the precise control of facet properties.</jats:p>","lang":"eng"}],"status":"public","date_updated":"2023-08-16T10:53:00Z","publisher":"MDPI AG","author":[{"first_name":"Bhanu K.","full_name":"Pothineni, Bhanu K.","last_name":"Pothineni"},{"first_name":"Sabrina","full_name":"Kollmann, Sabrina","last_name":"Kollmann"},{"full_name":"Li, Xinyang","last_name":"Li","first_name":"Xinyang"},{"last_name":"Grundmeier","id":"194","full_name":"Grundmeier, Guido","first_name":"Guido"},{"first_name":"Denise J.","last_name":"Erb","full_name":"Erb, Denise J."},{"first_name":"Adrian","full_name":"Keller, Adrian","id":"48864","orcid":"0000-0001-7139-3110","last_name":"Keller"}],"date_created":"2023-08-16T10:52:25Z","volume":24,"title":"Adsorption of Ferritin at Nanofaceted Al2O3 Surfaces","doi":"10.3390/ijms241612808","publication_status":"published","publication_identifier":{"issn":["1422-0067"]},"issue":"16","year":"2023","citation":{"short":"B.K.

The Laser-Powder-Bed-Fusion (L-PBF) and Laser-Metal-Deposition (LMD) processes are considered, as they differ fundamentally in the way a part is manufactured. (2) Known process parameters for low-porosity parts were used to fabricate tensile strength specimens. Half of the specimens were heat-treated, and all specimens were tested for mechanical properties in a quasi-static tensile test. In addition, the material hardness was determined. (3) It was found that, firstly, heat treatment resulted in a sharp increase in mechanical properties such as hardness, elastic modulus, yield strength and ultimate strength. In addition to the increase in these properties, the elongation at break also decreases significantly after heat treatment. The choice of process, on the other hand, does not give either process a clear advantage in terms of mechanical properties but shows that it is necessary to consider the essential mechanical properties for a desired application.</jats:p>","lang":"eng"}],"file":[{"date_created":"2024-11-22T15:55:07Z","creator":"cboedger","date_updated":"2024-11-22T15:55:07Z","file_id":"57334","access_level":"closed","file_name":"crystals-13-00157.pdf","file_size":5838834,"content_type":"application/pdf","relation":"main_file","success":1}],"date_updated":"2025-03-18T12:45:57Z","author":[{"first_name":"Stefan","last_name":"Gnaase","id":"25730","full_name":"Gnaase, Stefan"},{"last_name":"Niggemeyer","full_name":"Niggemeyer, Dennis","id":"77214","first_name":"Dennis"},{"last_name":"Lehnert","full_name":"Lehnert, Dennis","id":"90491","first_name":"Dennis"},{"id":"93904","full_name":"Bödger, Christian","last_name":"Bödger","first_name":"Christian"},{"first_name":"Thomas","id":"553","full_name":"Tröster, Thomas","last_name":"Tröster"}],"volume":13,"doi":"10.3390/cryst13020157","publication_status":"published","publication_identifier":{"issn":["2073-4352"]},"citation":{"apa":"Gnaase, S., Niggemeyer, D., Lehnert, D., Bödger, C., &#38; Tröster, T.

Here, we investigate the salting-out of different DNA origami shapes by the kosmotropic salt ammonium sulfate that is routinely employed in protein precipitation. We find that centrifugation in the presence of 3 M ammonium sulfate results in notable precipitation of DNA origami nanostructures but not of double-stranded genomic DNA. The precipitated DNA origami nanostructures can be resuspended in ammonium sulfate-free buffer without apparent formation of aggregates or loss of structural integrity. Even though quasi-1D six-helix bundle DNA origami are slightly less susceptible toward salting-out than more compact DNA origami triangles and 24-helix bundles, precipitation and recovery yields appear to be mostly independent of DNA origami shape and superstructure. Exploiting the specificity of ammonium sulfate salting-out for DNA origami nanostructures, we further apply this method to separate DNA origami triangles from genomic DNA fragments in a complex mixture. Our results thus demonstrate the possibility of concentrating and purifying DNA origami nanostructures by ammonium sulfate-induced salting-out.</jats:p>"}],"publication":"International Journal of Molecular Sciences","keyword":["Inorganic Chemistry","Organic Chemistry","Physical and Theoretical Chemistry","Computer Science Applications","Spectroscopy","Molecular Biology","General Medicine","Catalysis"],"language":[{"iso":"eng"}]},{"doi":"10.1016/j.jcrysgro.2022.126756","title":"Remote epitaxy of InxGa1-xAs (0 0 1) on graphene covered GaAs(0 0 1) substrates","volume":593,"author":[{"first_name":"T.","last_name":"Henksmeier","full_name":"Henksmeier, T."},{"first_name":"J.F.","full_name":"Schulz, J.F.","last_name":"Schulz"},{"first_name":"E.","last_name":"Kluth","full_name":"Kluth, E."},{"last_name":"Feneberg","full_name":"Feneberg, M.","first_name":"M."},{"first_name":"R.","full_name":"Goldhahn, R.","last_name":"Goldhahn"},{"first_name":"A.M.","last_name":"Sanchez","full_name":"Sanchez, A.M."},{"first_name":"M.","last_name":"Voigt","full_name":"Voigt, M."},{"last_name":"Grundmeier","id":"194","full_name":"Grundmeier, Guido","first_name":"Guido"},{"full_name":"Reuter, Dirk","id":"37763","last_name":"Reuter","first_name":"Dirk"}],"date_created":"2022-06-23T06:17:32Z","date_updated":"2022-06-23T06:18:32Z","publisher":"Elsevier BV","intvolume":"       593","citation":{"ama":"Henksmeier T, Schulz JF, Kluth E, et al.

However, our molecular understanding of the interaction of Gdm with proteins and DNA is still rather limited. Here, we investigated the denaturation of DNA origami nanostructures by three Gdm salts, i.e., guanidinium chloride (GdmCl), guanidinium sulfate (Gdm2SO4), and guanidinium thiocyanate (GdmSCN), at different temperatures and in dependence of incubation time. Using DNA origami nanostructures as sensors that translate small molecular transitions into nanostructural changes, the denaturing effects of the Gdm salts were directly visualized by atomic force microscopy. GdmSCN was the most potent DNA denaturant, which caused complete DNA origami denaturation at 50 °C already at a concentration of 2 M. Under such harsh conditions, denaturation occurred within the first 15 min of Gdm exposure, whereas much slower kinetics were observed for the more weakly denaturing salt Gdm2SO4 at 25 °C. Lastly, we observed a novel non-monotonous temperature dependence of DNA origami denaturation in Gdm2SO4 with the fraction of intact nanostructures having an intermediate minimum at about 40 °C. Our results, thus, provide further insights into the highly complex Gdm–DNA interaction and underscore the importance of the counteranion species.</jats:p>"}],"publication":"International Journal of Molecular Sciences","type":"journal_article"},{"year":"2022","citation":{"apa":"Verma, A.

In the homo- and heteroleptic complexes [Fe(cpmp)2]2+ (12+) and [Fe(cpmp)(ddpd)]2+ (22+) with the tridentate ligands 6,2’’-carboxypyridyl-2,2’-methylamine-pyridyl-pyridine (cpmp) and N,N’-dimethyl-N,N’-di-pyridin-2-ylpyridine-2,6-diamine (ddpd) two or one dipyridyl ketone moieties provide low energy π* acceptor orbitals. A good metal-ligand orbital overlap to increase the ligand field splitting is achieved by optimizing the octahedricity through CO and NMe units between the coordinating pyridines which enable the formation of six-membered chelate rings. The push-pull ligand cpmp provides intra-ligand and ligand-to-ligand charge transfer (ILCT, LL'CT) excited states in addition to MLCT excited states. Ground and excited state properties of 12+ and 22+ were accessed by X-ray diffraction analyses, resonance Raman spectroscopy, (spectro)electrochemistry, EPR spectroscopy, X-ray emission spectroscopy, static and time-resolved IR and UV/Vis/NIR absorption spectroscopy as well as quantum chemical calculations."}],"status":"public","type":"journal_article","publication":"ChemCatChem"},{"citation":{"apa":"Weber, S., Zimmermann, R.

For this, two cellular solids having nested and non-nested structures are designed and additively manufactured via laser powder bed fusion. The primary objective is to design cellular solids which absorb a significant amount of energy upon impact loading without transmitting a high amount of stress into the cellular solids. Therefore, compression testing of the two cellular solids is performed. The nested and non-nested cellular solids show similar energy absorption properties; however, the nested cellular solid transmits a lower amount of stress in the cellular structure compared to the non-nested cellular solid. The experimentally measured strain (by DIC) in the interior region of the nested cellular solid is lower despite a higher value of externally imposed compressive strain. The second objective of this study is to determine the thermal insulation properties of cellular solids. For measuring the thermal insulation properties, the samples are placed on a hot plate; and the surface temperature distribution is measured by an infrared camera. The thermal insulating performance of both cellular types is sufficient for temperatures exceeding 100 °C. However, the thermal insulating performance of a non-nested cellular solid is slightly better than that of the nested cellular solid. Additional thermal simulations predict a relatively higher temperature distribution on the cellular solid surfaces compared to experimental results. The simulated residual stress shows a similar distribution for both types, but the magnitude of residual stress is different for the cellular solids upon cooling from different temperatures of the hot plate.</jats:p>","lang":"eng"}]},{"citation":{"chicago":"Pramanik, Sudipta, Dennis Milaege, Kay-Peter Hoyer, and Mirko Schaper. “Additively Manufactured Nested and Non-Nested Cellular Solids for Effective Stress Distribution and Thermal Insulation Applications: An Experimental and Finite Element Analysis Study.” <i>Crystals</i> 12, no. 9 (2022). <a href=\"https://doi.org/10.3390/cryst12091217\">https://doi.org/10.3390/cryst12091217</a>.","ieee":"S.

For this, two cellular solids having nested and non-nested structures are designed and additively manufactured via laser powder bed fusion. The primary objective is to design cellular solids which absorb a significant amount of energy upon impact loading without transmitting a high amount of stress into the cellular solids. Therefore, compression testing of the two cellular solids is performed. The nested and non-nested cellular solids show similar energy absorption properties; however, the nested cellular solid transmits a lower amount of stress in the cellular structure compared to the non-nested cellular solid. The experimentally measured strain (by DIC) in the interior region of the nested cellular solid is lower despite a higher value of externally imposed compressive strain. The second objective of this study is to determine the thermal insulation properties of cellular solids. For measuring the thermal insulation properties, the samples are placed on a hot plate; and the surface temperature distribution is measured by an infrared camera. The thermal insulating performance of both cellular types is sufficient for temperatures exceeding 100 °C. However, the thermal insulating performance of a non-nested cellular solid is slightly better than that of the nested cellular solid. Additional thermal simulations predict a relatively higher temperature distribution on the cellular solid surfaces compared to experimental results. The simulated residual stress shows a similar distribution for both types, but the magnitude of residual stress is different for the cellular solids upon cooling from different temperatures of the hot plate.</jats:p>","lang":"eng"}],"type":"journal_article","publication":"Crystals","language":[{"iso":"eng"}],"article_number":"1217","keyword":["Inorganic Chemistry","Condensed Matter Physics","General Materials Science","General Chemical Engineering"],"user_id":"48411","department":[{"_id":"9"},{"_id":"158"}],"_id":"41489"},{"status":"public","type":"journal_article","_id":"31019","user_id":"94","department":[{"_id":"163"}],"citation":{"apa":"Watt, F.
