(Cation)2C2O4∙nSnPh2C2O4(n=1, 2; cation=Pr2NH2, MeNH3) AND SOME OF THEIR ADDUCTS: SYNTHESIS, INFRARED AND MOSSBAUER STUDIES

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2014
Three [SnPh2(C2O4)2]2- containing new adducts have been synthesized and characterized by elemental analyses, infrared and Mossbauer spectroscopy, the suggested structures being discrete, the SnPh2 residues octahedral cis or trans coordinated.

Electronic Structure and Bulk Spin Valve Behavior in Ca$_3$Ru$_2$O$_7$

, 2005
We report density functional calculations of the magnetic properties and Fermiology of Ca$_3$Ru$_2$O$_7$. The ground state consists of ferromagnetic bilayers, stacked antiferromagnetically. The bilayers are almost but not exactly half-metallic.

Vesignieite: a $S = \frac{1}{2}$ kagome antiferromagnet with dominant third-neighbor exchange [PDF]

, 2018
The spin-$\frac{1}{2}$ kagome antiferromagnet is an archetypal frustrated system predicted to host a variety of exotic magnetic states. We show using neutron scattering measurements that deuterated vesignieite BaCu$_{3}$V$_{2}$O$_{8}$(OD)$_{2}$, a fully ...

Using In Situ TEM to Understand the Surfaces of Electrocatalysts at Reaction Conditions: Single‐Atoms to Nanoparticles

Advanced Functional Materials, EarlyView.
This review summarizes recent advances in closed‐cell in situ TEM strategies for accurate determination of the activity and stability of single‐atom catalyst systems during operation. Operando conditions causing dynamic changes of SAC systems are highlighted and we explain why ensemble average‐based optical techniques may benefit from the technological

Bis[6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinato]nickel(II)–aqua[6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinic acid]dithiocyanatonickel(II) (1/1)

Acta Crystallographica Section E, 2008
In the title cocrystal, [Ni(C11H10N3O2)2]·[Ni(NCS)2(C11H11N3O2)(H2O)], both NiII ions are in disorted octahedral coordination environments. One NiII ion is coordinated by four N atoms and two O atoms from two tridentate 6-(3,5-dimethyl-1H-pyrazol-1 ...

GeAl2‐2xFe2xO3(OH)4 Nanotubes: New Electrocatalyst for Oxygen Evolution Reaction

Advanced Functional Materials, EarlyView.
Fe‐doped imogolite nanotubes are synthesized via a one‐step hydrothermal method with varying Fe substitution ratios x. Structural and spectroscopic analyses confirm homogeneous Fe incorporation while preserving tubular shape. Optimal doping at x = 0.05 enhances optical absorption, narrows band gap, reduces charge transfer resistance, and significantly ...
