1D and 3D Carbon Nanomaterials Derived from Zeolite‐Based Catalysts: Synthesis and Applications

Small Structures, Volume 7, Issue 3, March 2026.
Zeolites act as catalysts or catalytic templates to synthesize 1D and 3D carbon nanomaterials with uniform structures, enabled by their high surface area and uniform porous frameworks. The resulting carbon nanomaterials possess excellent surface area and electronic conductivity, supporting their use in energy storage, catalysis, electronics, gas ...

Controls on Iron‐Redox State in Martian Magmas Quantified by Mössbauer Spectroscopy, Colorimetric Wet Chemistry, and XANES Spectroscopy

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract To elucidate the relationship between oxygen fugacities (fO2) recorded in martian basalts and redox processes in the martian interior, superliquidus 100‐kPa furnace experiments on a composition similar to Humphrey (Adirondack basalt) were conducted at variable fO2 and temperature. Quenched glasses were analyzed by EPMA, Mössbauer spectroscopy,

Heat Transfer in Nuclear Waste Glasses: Measurements and Modeling of Thermal Radiation Properties

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
ABSTRACT We measured and modeled near‐infrared extinction of nuclear waste glasses from 300°C to 1150°C to enable predictive radiation heat transfer and thermal conductivity estimates. A composition‐ and redox‐informed model resolved contributions from key chromophores (Fe+2‐O‐Fe+3, V+4, free and bonded ≡Si‐OH groups) and, when present, spinel ...

Thermal decomposition of illite

Materials Research, 2004
The effect of heat treatment on illite in air at temperatures ranging from 750 to 1150 °C was studied using the Mössbauer effect in 57Fe. The dependence of the Mössbauer parameters and relative percentage of the radiation absorption area was measured as ...

New Heptacoordinated Organotin(IV) Complexes Derivatives of 2,6-diacetylpyridinebis(2-furanoylhydrazone), H2dapf, and 2,6-diacetylpyridinebis(2-thenoylhydrazone), H2dapt: Crystal and Molecular Structure of [Me2Sn(Hdapt]Br.H2O

Journal of the Brazilian Chemical Society, 1999
The reaction of the ligands H2dapf and H2dapt, with R4-mSnXm (m = 2, 3; R = Me, Ph and X = Cl, Br) led to the formation of eight new heptacoordinated organotin(IV) complexes, which were studied by microanalysis, IR, NMR and Mössbauer spectroscopy to ...
