Electrolyte alkali metal cations have been shown to modify the activity and reaction intermediates, however, the exact mechanism is at question due to unexplained deviations from the cation size trend. Our X-ray absorption spectroelectrochemical results show that bigger cations shift the Ni2+/(3+δ)+ redox peak and OER activity to lower potentials (however, with typical discrepancies), following the order CsOH > NaOH ≈ KOH > RbOH > LiOH. Here, we find that the OER activity follows the variations in electrolyte pH rather than a specific cation, which accounts for differences both in basicity of the alkali hydroxides and other contributing anomalies. Our density functional theory-derived reactivity descriptors confirm that cations impose negligible effect on the Lewis acidity of Ni, Fe, and O lattice sites, thus strengthening the conclusions of an indirect pH effect. article_number: '6181' author: - first_name: Mikaela full_name: Görlin, Mikaela last_name: Görlin - first_name: Joakim full_name: Halldin Stenlid, Joakim last_name: Halldin Stenlid - first_name: Sergey full_name: Koroidov, Sergey last_name: Koroidov - first_name: Hsin-Yi full_name: Wang, Hsin-Yi last_name: Wang - first_name: Mia full_name: Börner, Mia last_name: Börner - first_name: Mikhail full_name: Shipilin, Mikhail last_name: Shipilin - first_name: Aleksandr full_name: Kalinko, Aleksandr last_name: Kalinko - first_name: Vadim full_name: Murzin, Vadim last_name: Murzin - first_name: Olga V. full_name: Safonova, Olga V. last_name: Safonova - first_name: Maarten full_name: Nachtegaal, Maarten last_name: Nachtegaal - first_name: Abdusalam full_name: Uheida, Abdusalam last_name: Uheida - first_name: Joydeep full_name: Dutta, Joydeep last_name: Dutta - first_name: Matthias full_name: Bauer, Matthias id: '47241' last_name: Bauer orcid: 0000-0002-9294-6076 - first_name: Anders full_name: Nilsson, Anders last_name: Nilsson - first_name: Oscar full_name: Diaz-Morales, Oscar last_name: Diaz-Morales citation: ama: Görlin M, Halldin Stenlid J, Koroidov S, et al.

However, the FIB systems proposed so far suffer from poor cycling performance. In this work, we report La2NiO4.13 with a Ruddlesden-Popper type structure as an intercalation-based active cathode material in all solid-state FIB with excellent cycling performance. The critical charging conditions to maintain the conductivity of the cell were determined, which seems to be a major obstacle towards improving the cycling stability of FIBs. For optimized operating conditions, a cycle life of about 60 cycles and over 220 cycles for critical cut-off capacities of 50 mAh/g and 30 mAh/g, respectively, could be achieved, with average Coulombic efficiencies between 95 – 99%. Cycling of the cell is a result of fluorination/de-fluorination into and from the La2NiO4+d cathode, and it is revealed that La2NiO4.13 is a multivalent electrode material. Our findings suggest that La2NiO4.13 is a promising high energy cathode for FIBs. article_number: '27' author: - first_name: Mohammad Ali full_name: Nowroozi, Mohammad Ali last_name: Nowroozi - first_name: Kerstin full_name: Wissel, Kerstin last_name: Wissel - first_name: Manuel full_name: Donzelli, Manuel last_name: Donzelli - first_name: Niloofar full_name: Hosseinpourkahvaz, Niloofar last_name: Hosseinpourkahvaz - first_name: Sergi full_name: Plana-Ruiz, Sergi last_name: Plana-Ruiz - first_name: Ute full_name: Kolb, Ute last_name: Kolb - first_name: Roland full_name: Schoch, Roland id: '48467' last_name: Schoch orcid: 0000-0003-2061-7289 - first_name: Matthias full_name: Bauer, Matthias id: '47241' last_name: Bauer - first_name: Ali Muhammad full_name: Malik, Ali Muhammad last_name: Malik - first_name: Jochen full_name: Rohrer, Jochen last_name: Rohrer - first_name: Sergei full_name: Ivlev, Sergei last_name: Ivlev - first_name: Florian full_name: Kraus, Florian last_name: Kraus - first_name: Oliver full_name: Clemens, Oliver last_name: Clemens citation: ama: Nowroozi MA, Wissel K, Donzelli M, et al.

They can be obtained from a variety of different polymer precursors via electrospinning. While some methods have been tested for post-carbonization doping of nanofibers with the desired ingredients, very little is known about carbonization of blend nanofibers from two or more polymeric precursors. In this paper, we report on the preparation, thermal treatment and resulting properties of poly(acrylonitrile) (PAN)/poly(vinylidene fluoride) (PVDF) blend nanofibers produced by wire-based electrospinning of binary polymer solutions. Using a wide variety of spectroscopic, microscopic and thermal characterization methods, the chemical and morphological transition during oxidative stabilization (280 °C) and incipient carbonization (500 °C) was thoroughly investigated. Both PAN and PVDF precursor polymers were detected and analyzed qualitatively and quantitatively during all stages of thermal treatment. Compared to pure PAN nanofibers, the blend nanofibers showed increased fiber diameters, strong reduction of undesired morphological changes during oxidative stabilization and increased conductivity after carbonization. article_number: '1210' article_type: original author: - first_name: Martin full_name: Wortmann, Martin last_name: Wortmann - first_name: Natalie full_name: Frese, Natalie last_name: Frese - first_name: Al full_name: Mamun, Al last_name: Mamun - first_name: Marah full_name: Trabelsi, Marah last_name: Trabelsi - first_name: Waldemar full_name: Keil, Waldemar last_name: Keil - first_name: Björn full_name: Büker, Björn last_name: Büker - first_name: Ali full_name: Javed, Ali last_name: Javed - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Elmar full_name: Moritzer, Elmar id: '20531' last_name: Moritzer - first_name: Andrea full_name: Ehrmann, Andrea last_name: Ehrmann - first_name: Andreas full_name: Hütten, Andreas last_name: Hütten - first_name: Claudia full_name: Schmidt, Claudia id: '466' last_name: Schmidt orcid: 0000-0003-3179-9997 - first_name: Armin full_name: Gölzhäuser, Armin last_name: Gölzhäuser - first_name: Bruno full_name: Hüsgen, Bruno last_name: Hüsgen - first_name: Lilia full_name: Sabantina, Lilia last_name: Sabantina citation: ama: Wortmann M, Frese N, Mamun A, et al.

Proton conductivity was studied by impedance spectroscopy, using a single crystal. By varying the relative humidity (70–95%), temperature (21–60 °C), and orientation of the crystal relative to the electrical potential, it was found that proton conduction occurs predominantly through the linear, unidirectional (1D) micropore channels of Co-MOF-74, and that water molecules inside the channels are responsible for the proton mobility by a Grotthuss-type mechanism. article_number: '1263' article_type: original author: - first_name: Ali full_name: Javed, Ali last_name: Javed - first_name: Ina full_name: Strauss, Ina last_name: Strauss - first_name: Hana full_name: Bunzen, Hana last_name: Bunzen - first_name: Jürgen full_name: Caro, Jürgen last_name: Caro - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 citation: ama: Javed A, Strauss I, Bunzen H, Caro J, Tiemann M.

Here, we present a versatile template-assisted synthesis of nanostructured tin dioxide thin films using cellulose nanocrystals (CNCs). We demonstrate that the structural features of CNC-templated tin dioxide films strongly depend on the precursor composition. The precursor properties were studied by using low-temperature nuclear magnetic resonance spectroscopy of tin tetrachloride in solution. We demonstrate that it is possible to optimize the precursor conditions to obtain homogeneous precursor mixtures and therefore highly porous thin films with pore dimensions in the range of 10–20 nm (ABET = 46–64 m2 g–1, measured on powder). Finally, by exploiting the high surface area of the material, we developed a resistive gas sensor based on CNC-templated tin dioxide. The sensor shows high sensitivity to carbon monoxide (CO) in ppm concentrations and low cross-sensitivity to humidity. Most importantly, the sensing kinetics are remarkably fast; both the response to the analyte gas and the signal decay after gas exposure occur within a few seconds, faster than in standard SnO2-based CO sensors. This is attributed to the high gas accessibility of the very thin porous film. article_type: original author: - first_name: Alesja full_name: Ivanova, Alesja last_name: Ivanova - first_name: Bruno full_name: Frka-Petesic, Bruno last_name: Frka-Petesic - first_name: Andrej full_name: Paul, Andrej last_name: Paul - first_name: Thorsten full_name: Wagner, Thorsten last_name: Wagner - first_name: Askhat N. full_name: Jumabekov, Askhat N. last_name: Jumabekov - first_name: Yury full_name: Vilk, Yury last_name: Vilk - first_name: Johannes full_name: Weber, Johannes last_name: Weber - first_name: Jörn full_name: Schmedt auf der Günne, Jörn last_name: Schmedt auf der Günne - first_name: Silvia full_name: Vignolini, Silvia last_name: Vignolini - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Dina full_name: Fattakhova-Rohlfing, Dina last_name: Fattakhova-Rohlfing - first_name: Thomas full_name: Bein, Thomas last_name: Bein citation: ama: Ivanova A, Frka-Petesic B, Paul A, et al.

Hydrogel micropatterns are fabricated by spreading the prepolymer mixture on the substrate, followed by UV photopolymerization through a micropatterned mask. The hydrogel is covalently bonded to the substrate surface. Al2O3 is produced by swelling the hydrogel in a saturated aluminum nitrate solution and subsequent thermal conversion/calcination. As a result, micropatterned porous Al2O3 microdots with heights in µm range and large specific surface areas up to 274 m2 g−1 are obtained. Hence, the hydrogel fulfills a dual templating function, namely micropatterning and nanoporosity generation. The impact of varying the photopolymerization time on the properties of the products is studied. Samples are characterized by light and confocal laser scanning microscopy, scanning electron microscopy, energy-dispersive x-ray spectrometry, and Kr physisorption analysis. article_number: '445601' article_type: original author: - first_name: Zimei full_name: Chen, Zimei last_name: Chen - first_name: Dirk full_name: Kuckling, Dirk id: '287' last_name: Kuckling - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 citation: ama: Chen Z, Kuckling D, Tiemann M.

To achieve highly ordered inverse opal structures, one important issue during the colloidal crystal templating procedure is to form a stable precursor network before the template loses its structural integrity at high temperature. Using poly(methyl methacrylate), PMMA, colloidal crystal templates, it is essential to consider the physical and chemical changes of the precursors induced by the changes of PMMA during the thermal conversion. For a systematic investigation of this matter, we synthesized a variety of metal oxide inverse opals from the respective metal nitrates, including Cr2O3, Ga2O3, Fe2O3, In2O3, CuO, CeO2, and ZnO, to compare the effect of various modifications of precursors on the structural and optical properties. When the nitrate precursors have a lower thermal stability than the PMMA template, we have modified the metal nitrates by chelating or by polyacrylamide gelation to form more stable precursor networks. article_type: original author: - first_name: Xuyang full_name: Zhang, Xuyang last_name: Zhang - first_name: Christian full_name: Weinberger, Christian id: '11848' last_name: Weinberger - first_name: Sabrina full_name: Amrehn, Sabrina last_name: Amrehn - first_name: Xia full_name: Wu, Xia last_name: Wu - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Thorsten full_name: Wagner, Thorsten last_name: Wagner citation: ama: Zhang X, Weinberger C, Amrehn S, Wu X, Tiemann M, Wagner T.

Two distinct conduction mechanisms are identified. Water-mediated conductance along the crystal surface occurs by mass transport, as evidenced by a high activation energy (0.54 eV). In addition, intrinsic conduction by proton ′hopping′ through the interior of the crystal with a low activation energy (0.31 eV) is observed. This latter conduction is anisotropic with respect to the crystal structure and seems to occur through a channel along the c axis of the orthorhombic crystal. Proton conduction is assumed to be mediated by sulfonate groups and non-coordinating water molecules that are part of the crystal structure. article_type: original author: - first_name: Ali full_name: Javed, Ali last_name: Javed - first_name: Thorsten full_name: Wagner, Thorsten last_name: Wagner - first_name: Stephan full_name: Wöhlbrandt, Stephan last_name: Wöhlbrandt - first_name: Norbert full_name: Stock, Norbert last_name: Stock - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 citation: ama: 'Javed A, Wagner T, Wöhlbrandt S, Stock N, Tiemann M.

In the present study different dimensionless joining displacements are accounted for. The results show that high short-term tensile strength does not directly transfer to high long-term tensile strength. The morphology of the weld seam in the joined samples is examined by means of transmitted and reflected light microscopy. For the dimensionless joining displacements of 0.75 and 0.95, stretched spherulites are obtained. X-Ray diffraction can be used as a tool for qualitative and quantitative analysis and eventually for differentiation of samples of various joining displacements. author: - first_name: Andrea full_name: Wübbeke, Andrea id: '12504' last_name: Wübbeke - first_name: Volker full_name: Schöppner, Volker last_name: Schöppner - first_name: André full_name: Paul, André last_name: Paul - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Laura full_name: Austermeier, Laura last_name: Austermeier - first_name: Marcus full_name: Fitze, Marcus last_name: Fitze - first_name: Mingie full_name: Chen, Mingie last_name: Chen - first_name: Fabian full_name: Jakob, Fabian last_name: Jakob - first_name: Hans-Peter full_name: Heim, Hans-Peter last_name: Heim - first_name: Tao full_name: Wu, Tao last_name: Wu - first_name: Thomas full_name: Niendorf, Thomas last_name: Niendorf - first_name: Marie-Luise full_name: Röhricht, Marie-Luise last_name: Röhricht - first_name: Michael full_name: Schmidt, Michael last_name: Schmidt citation: ama: 'Wübbeke A, Schöppner V, Paul A, et al.

The materials possess fine-leaved structures at their particle surface (nanowall hollow micro spheres). Morphology control is achieved by citric acid used as an additive in variable relative quantities during the synthesis. The structure formation is studied by various time-dependent ex situ methods, such as scanning electron microscopy, x-ray diffraction, and Raman spectroscopy. The fine-leaved surface structure is characterized by high-resolution transmission electron microscopy techniques (HRTEM, STEM), using a high-angle annular dark field detector, as well as by differential phase contrast analysis. In-depth structural characterization of the nanowalls by drop-by-drop ex situ FE-SEM analysis provides insight into possible structure formation mechanisms.

However, the substitution of noble metals, which are almost exclusively used, by base metals remains a major challenge on the way to a more sustainable world.1 Iron is a dream candidate for this ambitious aim.2 But compared to noble metal complexes that show long-lived metal-to-ligand charge-transfer (MLCT) states, realization of emissive and photoactive iron complexes is demanding, due to the fast deactivation of charge transfer states into non-emissive inactive states. No MLCT emission has been observed for monometallic iron complexes before. Consequently, dual emission could also not yet be realized with iron complexes, as it is a very rare property even of noble metal compounds. Here we report the FeIII complex [Fe(ImP)2][PF6] (HImP = 1,1’-(1,3-phenylene)bis(3-methyl-1-imidazol-2-ylidene)), showing Janus-type dual emission by combining LMCT (ligand-to-metal charge transfer) with MLCT luminescence. The respective excited states are characterized by a record lifetime of τMLCT = 4.2 ns, and a moderate τLMCT = 0.2 ns. Only two emissive FeIII compounds are known so far and they show LMCT luminescence only.3,4 The unique properties of the presented complex are caused by the specific ligand design combining four N-heterocyclic carbenes with two cyclometalating groups, using the σ-donor strength of six carbon atoms and the acceptor capabilities of the central phenyl rings. Spectroscopically, doublet manifolds could be identified in the deactivation process, while (TD)DFT analysis revealed the presence of quartets as well. With three key advancements of realizing the first iron complex showing dual luminescence, a MLCT luminescence and a world record MLCT lifetime, the results constitute a basis for future application of iron complexes as white light emitters and new photocatalytic reactions making use of the Janus-type properties of the developed complex. author: - first_name: Matthias full_name: Bauer, Matthias id: '47241' last_name: Bauer orcid: 0000-0002-9294-6076 - first_name: Jakob full_name: Steube, Jakob id: '40342' last_name: Steube orcid: 0000-0003-3178-4429 - first_name: Ayla full_name: Päpcke, Ayla last_name: Päpcke - first_name: Olga full_name: Bokareva, Olga last_name: Bokareva - first_name: Thomas full_name: Reuter, Thomas last_name: Reuter - first_name: Serhiy full_name: Demeshko, Serhiy last_name: Demeshko - first_name: Roland full_name: Schoch, Roland id: '48467' last_name: Schoch orcid: 0000-0003-2061-7289 - first_name: Stephan full_name: Hohloch, Stephan last_name: Hohloch - first_name: Franc full_name: Meyer, Franc last_name: Meyer - first_name: Katja full_name: Heinze, Katja last_name: Heinze - first_name: Oliver full_name: Kühn, Oliver last_name: Kühn - first_name: Stefan full_name: Lochbrunner, Stefan last_name: Lochbrunner citation: ama: Bauer M, Steube J, Päpcke A, et al.
