Tabler, Andreas; Häusser, Anette; Roduner, Emil (Elsevier, 2013-11)Various Cu/HZSM5-zeolites were prepared and their catalytic properties were investigated by productanalysis via GC/MS chromatography in order to trace down the mechanism of the gas phase one-stepoxidation of benzene to ...

Kittel, Tobias; Roduner, Emil (American Chemical Society, 2016)Metal oxide-supported nanoparticles of the platinum group metals Pt, Rh and Pd were studied at ambient temperature and atmosphere using Kelvin probe force microscopy. In all cases, the results reveal electron transfer ...
-
Roduner, Emil; Kittel, Tobias (American Chemical Society, 2016)Existing models for the analysis of Kelvin probe microscopy experiments are extended and used to analyze the experimental electrical potential profiles for a Pt/TiO2 model nanoparticle. The derived model reproduces in ...

Adegoke, Kayode Adesina; Radhakrishnan, Shankara Gayathri; Gray, Clarissa L.; Sowa, Barbara; Morais, Claudia; Rayess, Paul; Rohwer, Egmont Richard; Comminges, Clement; Kokoh, K. Boniface; Roduner, Emil (Royal Society of Chemistry, 2020-06)Formic acid is often assumed to be the first intermediate of carbon dioxide reduction to alcohols or hydrocarbons. Here we use co-electrolysis of water and aqueous formic acid in a PEM electrolysis cell with Nafion® as a ...
-
Roduner, Emil; Radhakrishnan, Shankara Gayathri (Royal Society of Chemistry, 2016)The Second Law of Thermodynamics is well known for determining the direction of spontaneous processes in laboratory, life and universe. It is therefore often called the arrow of time. Less often discussed but just as ...

Walker, J.A.; Mezyk, S.P.; Roduner, Emil; Bartels, D.M. (American Chemical Society, 2016)Relative diffusion coefficients were determined in water for the D, H, and Mu isotopes of atomic hydrogen by measuring their diffusion-limited spin-exchange rate constants with Ni2+ as a function of temperature. H and D ...
-
Roduner, Emil; Jensen, Christopher (MDPI Publishing, 2015)13-atom platinum nanoclusters have been synthesized quantitatively in the pores of the zeolites NaY and KL. They reveal highly interesting magnetic properties like high-spin states, a blocking temperature, and ...
-
Poetzsch, D.; Bach, T.; Zerpa Unda, J.E.; Roduner, Emil (Wiley, 2014-06)Methanol is considered a promising liquid fuel in context with electrochemical energy conversion and storage for mobile applications. It is shown here that a direct methanol fuel cell can be used for spontaneous charging ...
-
Roduner, Emil; Kruger, T.P.J. (Tjaart) (Elsevier, 2022-01)Understanding the origin of irreversibility in thermodynamics has been a fundamental scientific challenge and puzzle for nearly a century. Initially, the discussions related to classical thermodynamic systems, but recently ...

Roduner, Emil; Rohwer, Egmont Richard (Wiley Open Access, 2024-01)Ninety percent of the large interior, rural part of Africa is not an abundant user of fossil fuels and is not connected to an electricity grid. This limits habitability and leads to significant migration to larger cities ...
-
Keppeler, Melanie; Bräuning, G.; Radhakrishnan, Shankara Gayathri; Liu, X.; Roduner, Emil; Jensen, C. (Royal Society of Chemistry, 2016)Monodisperse Pt clusters of 132 atoms, supported on the zeolites NaY and KL and saturated with chemisorbed hydrogen, are investigated as well-defined model catalysts for reactions of CO, NO, O2 and ethene. CO reacts ...
-
Roduner, Emil (Elsevier, 2018-07)Electrochemical devices for energy conversion and storage applications have little in common with conventional electrochemistry. A significant advantage is the conversion of chemical into electrical energy and vice-versa, ...
-
Roduner, Emil (Royal Society of Chemistry, 2018)Properties of near-spherical metal clusters are best understood on the basis of the concept of conventional atoms. Their conduction electrons occupy cluster orbitals that remind of hydrogen-like orbitals since they have ...
-
Jensen, Christopher; Van Slageren, Joris; Jakes, Peter; Eichel, Rudiger A.; Roduner, Emil (American Chemical Society, 2013-11)Platinum clusters were prepared by ion exchange of a KL zeolite, followed by oxygen calcination and hydrogen reduction, and characterized by electron paramagnetic resonance (EPR) and hyperfine sublevel correlation ...
-
Roduner, Emil (MDPI, 2023-07-27)Spherical nanoclusters with countable member atoms and delocalized valence orbitals are superatoms with properties analogous to those of simple atoms. This is reflected, in particular, in their optical spectra and magnetic ...
-
Roduner, Emil; Rohwer, Egmont Richard (Springer, 2021-03)Since natural photosynthesis in our biosphere does not have the capacity to cope with the additional atmospheric CO2 due to combustion of fossil fuels, CO2 has to be actively removed. Efficient methods are currently being ...
-
Buyens, Dominique M.S.; Pilcher, Lynne A.; Roduner, Emil (Wiley, 2021-10)Rare anionic forms of nucleic acids play a significant biological role and lead to spontaneous mutations and replication and translational errors. There is a lack of information surrounding the stability and reactivity of ...
