Competing redox reactions in Fe-containing AlO(OH) and Al2O 3 matrices: A combined investigation by Mössbauer, ESR spectroscopy and thermal analysis

Stößer, R.; Menzel, M.; Feist, M.; Nofz, M.; Renz, Franz (Bristol : IOP Publishing Ltd., 2010)

The investigation of iron-doped AlO(OH)/Al2O3 systems revealed that the combined employment of Mössbauer and ESR spectroscopies together with thermal analysis yields meaningful data with complementary information. This ...
Iron oxide colloid mobility as affected by solid matrix wetting properties

Carstens, J.F.; Bachmann, J.; Neuweiler, I. (Washington, DC : Soil Science Society of America, 2018)

The influence of porous media wettability on the mobility of colloids is mostly unknown. In the present work, organic-matter-coated goethite (OMCG) colloids were percolated through three saturated soil materials differing ...
Photoelectrochemical and theoretical investigations of spinel type ferrites (MxFe3-xO4) for water splitting: A mini-review

Taffa, Dereje H.; Dillert, Ralf; Ulpe, Anna C.; Bauerfeind, Katharina C.L.; Bredow, Thomas; Bahnemann, Detlef W.; Wark, Michael (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)

Solar-assisted water splitting using photoelectrochemical cells (PECs) is one of the promising pathways for the production of hydrogen for renewable energy storage. The nature of the semiconductor material is the primary ...
Process sequence of soil aggregate formation disentangled through multi-isotope labelling

Amelung, Wulf; Meyer, Nele; Rodionov, Andrey; Knief, Claudia; Aehnelt, Michaela; Bauke, Sara L.; Biesgen, Danh; Dultz, Stefan; Guggenberger, Georg; Jaber, Maguy; Klumpp, Erwin; Kögel-Knabner, Ingrid; Nischwitz, Volker; Schweizer, Steffen A.; Wu, Bei; Totsche, Kai U.; Lehndorff, Eva (Amsterdam [u.a.] : Elsevier Science, 2022)

Microaggregates (<250 µm) are key structural subunits of soils. However, their formation processes, rates, and transformation with time are poorly understood. We took advantage of multiple isotope labelling of potential ...
Properties and structure of magnetic alkali-borosilicate glasses prepared by induction melting

Naberezhnov, A.; Nacke, B.; Nikanorov, A.; Koroleva, E.; Vanina, P.; Alekseeva, O.; Tomkovich, M.; Andreeva, N. (Bristol : Institute of Physics Publishing, 2018)

In this contribution we present the first results devoted to studies of structure, morphology and magnetic properties of magnetic alkali-borosilicate glasses prepared by induction melting. This procedure permits to fabricate ...
The size-selective interaction of key and lock nanocrystals driven by depletion attraction at the nanoscale

Hinrichs, D.; Himstedt, R.; Dorfs, Dirk (Cambridge : Royal Society of Chemistry, 2018)

In this article, we study the size-dependent interactions of quasi-spherical nanocrystals with voids of concave nanoparticles of complementary sizes and shapes. Experimental insights into a system with key and lock particles ...
