NO Reactions Inside Crystals

European Journal of Inorganic Chemistry, Volume 26, Issue 27, September 25, 2023., 2023
Solid‐state dicobalt complexes chemisorb the toxic greenhouse gas nitric oxide (NO) and facilitate its selective transformation in a solvent‐free reaction. In‐crystal dimetallic cooperativity is proposed. Depending on the counter anion present in the solid, a nitrite‐bridged dicobalt(II,III) or dicobalt(III,III) complex is synthesized in this gas‐solid

Influence of Framework n(Si)/n(Al) Ratio on the Nature of Cu Species in Cu‐ZSM‐5 for NH3‐SCR‐DeNOx

ChemCatChem, Volume 14, Issue 18, September 20, 2022., 2022
Copper‐containing zeolite: Changes in the zeolite preparation temperature result in the variation in the framework n(Si)/n(Al) ratio, and thus, the nature of copper species in the Cu‐containing ZSM‐5. Activity and selectivity of catalysts in NH3‐SCR‐DeNOx drop due to the presence of aggregated copper species.

[Ti(fpin)3]2−: a structurally characterized transition metal tris(perfluoropinacolato) complex

Zeitschrift für anorganische und allgemeine Chemie, Volume 647, Issue 18, Page 1815-1818, September 27, 2021., 2021
Abstract The reaction of TiCl3 ⋅ 3THF with perfluoropinacol (H2fpin), triethylamine and silver nitrite in acetonitrile yielded in the formation of the first tris(perfluoropinacolato) complex with a transition metal, (HNEt3)3[TiIV(fpin)3]NO2 (1). The compound was fully characterized with IR and UV‐vis spectroscopy as well as elemental analysis and ...

Mortadella sausage formulations with mechanically separated layer hen meat preblended with antioxidants Mortadela elaborada com cms de galinhas poedeiras pré-misturada com antioxidantes

Scientia Agricola, 2006
At the end of the laying cycle, layer hens can be used for production of mechanically separated meat (MSML) for sausage manufacture. However, mechanically separated meats are susceptible to lipid and pigment oxidation during storage, problems that could ...

Tomonaga-Luttinger Liquid in a Quasi-One-Dimensional S=1 Antiferromagnet Observed by the Specific Heat [PDF]

, 2005
Specific heat experiments on single crystals of the S=1 quasi-one-dimensional bond-alternating antiferromagnet Ni(C_9H_24N_4)(NO_2)ClO_4, alias NTENP, have been performed in magnetic fields applied both parallel and perpendicular to the spin chains.

The Red Color of Life Transformed – Synthetic Advances and Emerging Applications of Protoporphyrin IX in Chemical Biology

European Journal of Organic Chemistry, Volume 2020, Issue 22, Page 3171-3191, June 16, 2020., 2020
The use of the heme precursor protoporphyrin IX for biological applications has experienced a steep increase in recent years. Herein, we review possibilities for synthetic modification of this porphyrin scaffold and discuss its emerging key uses in the field of chemical biology. Protoporphyrin IX (PPIX) is the porphyrin scaffold of heme b, a ubiquitous
