Spectroscopic analysis confirmed the formation of highly dispersed multi-valent Cu2O/CuO on the thiol-functionalized cellulose, resulting in a highly efficient copper catalyst. This catalyst demonstrated excellent performance in the oxidative coupling of various amines to imines, achieving yields of 39–99% within 10–30 min. A key advantage of this system is its reusability; the catalyst maintained remarkable stability and activity over ten reaction cycles with straightforward recovery.

The main problem is that direct measurement, from both quantitative and qualitative point of view is challenging. While there are methods to assess solution strength and wettability of ionic liquids with cellulose materials, the main challenge lies in the combination of a solid substrate and an applied liquid, limiting the number of accessible methods. We demonstrate in this paper that an in-situ solid-state NMR spectroscopical approach is capable of monitoring in real-time the mobility of ionic liquids in cellulose-based substrates. Specifically, we employ 1H → 13C cross polarization magic angle spinning (CP MAS) NMR spectroscopy to examine mobility changes over varying exposure times in paper samples treated with ionic liquids. Through this approach, we capture the temporal evolution of IL signals, which in turn provide insights into mobility changes of ILs and also allow for identifying changes in cellulose crystallinity. The approach allows for a simple, semiquantitative assessment of cellulose solubility in ionic liquids and is in principle applicable to other biomass materials as well.","lang":"eng"}],"status":"public","_id":"64009","user_id":"100715","extern":"1","language":[{"iso":"eng"}]},{"doi":"10.1039/D5CC04700E","title":"Solid-state polycyclotrimerization of diynes to porous organic polymers","volume":61,"date_created":"2026-02-07T15:47:03Z","author":[{"last_name":"Hutsch","full_name":"Hutsch, Stefanie","first_name":"Stefanie"},{"first_name":"Sven","last_name":"Grätz","full_name":"Grätz, Sven"},{"first_name":"Jonas","last_name":"Lins","full_name":"Lins, Jonas"},{"first_name":"Torsten","last_name":"Gutmann","full_name":"Gutmann, Torsten","id":"118165"},{"first_name":"Lars","last_name":"Borchardt","full_name":"Borchardt, Lars"}],"publisher":"The Royal Society of Chemistry","date_updated":"2026-02-17T16:16:36Z","page":"15622–15625","intvolume":" 61","citation":{"ama":"Hutsch S, Grätz S, Lins J, Gutmann T, Borchardt L.

Nonetheless, sodium-ion batteries (SIBs) are often composed of flammable and volatile carbonate-based liquid electrolytes. Polymer electrolytes have attracted significant attention as safer alternatives. Among polymer electrolytes, single-ion conductive polymer electrolytes (SIPEs) are considered particularly interesting because they can suppress dendrite growth, enabling high-performance (quasi)-solid-state sodium–(metal) batteries. In this work, a self-standing, flexible, quasi-solid-state SIPE is investigated, which is composed of sodium 4-styrene sulfonyl (trifluoromethanesulfonyl) imide (NaSTFSI), pentaerythritol tetrakis(3-mercaptopropionate) (PETMP) and pentaerythritol tetraacrylate (PET4A) blended with poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP). The SIPE membrane, including 50 wt% of molecular transporter, exhibits ionic conductivity of 1.4 × 10−5 S cm−1 and 1.3 × 10−4 S cm−1 at 20 °C and 90 °C, respectively, thermal stability up to 280 °C, electrochemical stability window up to 4.5 V vs. Na/Na+, and Na plating/stripping reversibility in symmetric Na‖Na cells. The manufactured SIPE implemented in Prussian White (PW)‖Na cells enables the delivery of 147 mA h g−1 of PW at 15 mA g−1 with a Coulombic efficiency of over 99%, which is comparable with the PW‖Na cells using liquid carbonate electrolyte, confirming the suitability of the designed SIPE for sodium–(metal) batteries."}],"status":"public","publication":"Journal of Materials Chemistry A","type":"journal_article"},{"date_updated":"2026-02-17T16:12:41Z","publisher":"John Wiley & Sons, Ltd","volume":17,"date_created":"2026-02-07T16:18:53Z","author":[{"first_name":"Till","full_name":"Wissel, Till","last_name":"Wissel"},{"last_name":"Rösler","full_name":"Rösler, Lorenz","first_name":"Lorenz"},{"last_name":"Brodrecht","full_name":"Brodrecht, Martin","first_name":"Martin"},{"first_name":"Mark V.","last_name":"Höfler","full_name":"Höfler, Mark V."},{"first_name":"Kevin","full_name":"Herr, Kevin","last_name":"Herr"},{"full_name":"Oliveira Jr., Marcos","last_name":"Oliveira Jr.","first_name":"Marcos"},{"first_name":"Vytautas","last_name":"Klimavicius","full_name":"Klimavicius, Vytautas"},{"last_name":"Ebert","full_name":"Ebert, Martin","first_name":"Martin"},{"first_name":"Hergen","full_name":"Breitzke, Hergen","last_name":"Breitzke"},{"last_name":"Hoffmann","full_name":"Hoffmann, Markus","first_name":"Markus"},{"full_name":"Buntkowsky, Gerd","last_name":"Buntkowsky","first_name":"Gerd"},{"first_name":"Torsten","last_name":"Gutmann","full_name":"Gutmann, Torsten","id":"118165"}],"title":"Novel Heterogeneous Pd Catalysts for Cross-Coupling Reactions in Biocompatible Media: Structural Insights from Solid-State NMR Techniques","doi":"10.1002/cctc.202401511","publication_identifier":{"issn":["1867-3880"]},"year":"2024","intvolume":" 17","page":"e202401511","citation":{"apa":"Wissel, T., Rösler, L., Brodrecht, M., Höfler, M.

The amount of amine/carboxyl groups and vanillin/histidine methyl ester and thermal stability are determined by TGA and elemental analysis, while ICP-OES delivered the amount of palladium of the catalysts. The morphology is investigated by SEM and XPS and confirms the presence of coordinated palladium in the zero-oxidation state. Gas adsorption analysis is conducted, which indicates the presence of palladium clusters in one of the two catalysts, which is underlined by BSE images combined with EDX. A detailed 13C ssNMR and DNP-enhanced 15N ssNMR spectral analysis is presented, which provides ultimate proof of the successful syntheses of the catalysts. The coordination of the palladium onto the carrier material is shown by combining the NMR spectral results with the results of the other analytics.

Herein, we report on the use of zinc modified silicas as possible support materials for vanadium catalysts and the resulting consequences for the performance in the selective oxidation of methane to formaldehyde. After optimization of the Zn content and reaction conditions, a remarkably high space-time yield of 12.4 kgCH2O·kgcat−1·h−1 was achieved. As a result of the extensive characterization by means of UV–vis, Raman, XANES and NMR spectroscopy it was found that vanadium is in the vicinity of highly dispersed zinc atoms which promote the formation of active vanadium species as supposed by theoretical calculations.

Conducting this solid-state approach in a mixer ball mill with 4-Methylbenzonitrile, we synthesize Tris(4-methylphenyl)-1,3,5-triazine quantitatively in as little as 90 minutes. Just as fast, this mechanochemical method facilitates the synthesis of the covalent triazine framework CTF-1 using 1,4 Dicyanobenzene. Material characterization confirms its porous (650 m2 g-1) and crystalline nature. Adjusting the induced mechanical energy allows control over the obtained stacking conformation of the resulting CTFs - from a staggered AB arrangement to an eclipsed AA stacking conformation. Finally, a substrate scope demonstrates the versatility of this approach, successfully yielding various CTFs. This work presents, for the first time, the mechanochemical cyclotrimerization of nitriles. Utilizing Trifluoromethanesulfonic acid and a ball mill, both small molecules and large organic frameworks could be obtained. Screening the reaction of 1,4-Dicyanobenzene by various parameters, such as reaction time, frequency, or temperature, significant impacts on the porosity of the polymer and its crystallinity were revealed. image"}],"status":"public","_id":"63989","user_id":"100715","extern":"1","language":[{"iso":"eng"}]},{"user_id":"100715","_id":"63980","language":[{"iso":"eng"}],"extern":"1","type":"journal_article","publication":"Journal of Chemical & Engineering Data","status":"public","abstract":[{"text":"Density, viscosity, and self-diffusion coefficients are reported for octan-1-ol and the related ether-alcohols 2-pentoxy-ethan-1-ol, 3-butoxypropan-1-ol, 4-propoxybutan-1-ol, 5-ethoxypentan-1-ol, and 6-methoxyhexan-1-ol covering temperature ranges from 298.15 to 359.15 K. These new data reveal structure–property relationships affected by the presence and the position of the ether moiety in the molecular structure of the ether-alcohols. Compared to octan-1-ol, the presence of the ether moiety causes an increase in intermolecular hydrogen bonding interactions, resulting in higher densities. The increase in density is less pronounced for those ether-octanols that engage in intramolecular hydrogen bonding. As for the effects of the ether moiety on the dynamics, these are generally faster for the ether-alcohols compared to octan-1-ol, suggesting that hydrogen bonding between ether oxygen and hydroxy hydrogen is weaker compared to hydrogen bonding between two hydroxy groups. The activation energies obtained from an Arrhenius analysis are higher for translational motion than for momentum transfer for all alcohols. There are additional finer details across the ether alcohols for these activation barriers. These differences cancel out for the mathematical product of self-diffusion coefficient and viscosity (Dη). The effect of water impurities on the studied properties was also investigated and found to lead to small increases in densities for all alcohols. Viscosities decrease for octan-1-ol and 2-pentoxyethan-1-ol but increase for the other ether-alcohols that can engage in intramolecular hydrogen bonding.
