Covalent Functionalization of NiFe Layered Double Hydroxides using Tris(Hydroxymethyl)Aminomethane

Small, EarlyView.
Covalent functionalization of NiFe layered double hydroxides with tris(hydroxymethyl)aminomethane enables controlled growth, enhanced structural order, and improved processability. Temporary TRIS anchoring promotes stable water‐based inks and binder‐free electrode fabrication, leading to enhanced oxygen evolution activity and long‐term stability under ...

Insight into the evolution of the Tagish Lake carbonaceous chondrite by analysis of the oxygen isotopic composition of extracted water and Mössbauer spectroscopy [PDF]

, 2001
Analysis of oxygen isotopes in water from Tagish Lake together with Mössbauer Spectroscopy suggest some similarities to the CI group of meteorites but also suggest differences in the extent of parent body hydrothermal ...

2D Iron Oxide at the Graphene/SiC(0001) Interface

Small Methods, EarlyView.
2D iron oxide was successfully formed via intercalation of Fe and O into the graphene/SiC(0001) interface. Atomic‐resolution electron microscopy revealed that the 2D iron oxide is encapsulated by graphene and sharply interfaced with SiC. This material is suggested to exhibit antiferromagnetic behavior at low temperatures.

Cation Distribution in Natural Chromites from Oman

Sultan Qaboos University Journal for Science, 1996
Two specimens or natural chromite from the Oman ophiolite were studied using Mossbauer Spectroscopy (MS), X-ray Diffraction (XRD). and Scanning Electron Microscopy (SEM). The diffraction patterns obtained at room temperature showed that the two specimens

Spin relaxation in antiferromagnetic Fe–Fe dimers slowed down by anisotropic DyIII ions

Beilstein Journal of Nanotechnology, 2013
By using Mössbauer spectroscopy in combination with susceptibility measurements it was possible to identify the supertransferred hyperfine field through the oxygen bridges between DyIII and FeIII in a {Fe4Dy2} coordination cluster.
