Preparación y estudio del ácido N,N,N',N'- tetracarboximetiltiourea (ATMT) o ácido tiourea tetraacético
(Real Sociedad Española de Física y Química, 1976)
Se prepara un nuevo agente secuestrante o complexona de tipo poliaminopolicarboxílico, al que se ha denominado N,N,N',N'-tetracarboximetil-tiourea (ATMT) o ácido tioureatetraacético, con siete posiciones teóricas de ...

Alkane Metathesis over Immobilized Pincer-ligated Iridium Complexes: Effect of Support Nature
(Elsevier, 2023)
In this work, catalytic alkane metathesis has been evaluated as a suitable approach to upcycle hydrocarbons (polyolefins) at moderate temperatures. To this end, a pincer-ligated iridium complex (dehydrogenation catalyst) ...

Biochar Production from Cellulose under Reductant Atmosphere: Influence of the Total Pyrolysis Time
(Royal Society of Chemistry, 2023)
Today's rising energy costs, coupled with increasing energy demand, make it necessary to search for more efficient energy processes. In recent years, there have been increasing efforts to develop efficient catalysts based ...

A Genuine Germylene PGeP Pincer Ligand for Formic Acid Dehydrogenation with Iridium
(Royal Society of Chemistry, 2023)
We report an iridium system constructed around a long-tethered PGeP ligand that facilitates access to the less common germylene form, so far unreported for an ‘NHC-type’ Ge ligand. Its bonding is substantiated by computational ...

Cleavage of Carbon Dioxide C=O Bond Promoted by Nickel-Boron Cooperativity in a PBP-Ni Complex
(Wiley-Blackwell, 2023)
The synthesis and characterization of (tBuPBP)Ni(OAc) (5) by insertion of carbon dioxide into the Ni−C bond of (tBuPBP)NiMe (1) is presented. An unexpected CO2 cleavage process involving the formation of new B−O and Ni−CO ...

Charting a Path to Catalytic Upcycling of Plastic Micro/nano Fiber Pollution from Textiles to Produce Carbon Nanomaterials and Turquoise Hydrogen
(Royal Society of Chemistry, 2023)
Washing synthetic textile fibers releases micro/nano plastics, endangering the environment. As new filters and associated regulations are developed to prevent fiber release from washing machines, there emerges a need to ...

Electrical properties of bismuth ferrites: Bi2Fe4O9 and Bi25FeO39
(Elsevier, 2019)
Bi2Fe4O9 was prepared by solid-state reaction and the electrical properties measured by impedance spectro- scopy. After annealing in O2 at 900 °C, Bi2Fe4O9 is an electrically-homogeneous insulator. Its high frequency p ...
