Reinventar Valencia

open access: yes, 2008
Esta ponencia se plantea en el contexto de una Jornada de presentación de la Cátedra Ciudad que, con el nombre LA CIUDAD DE VALENCIA COMO OBJETO DE ESTUDIO podría, a su vez, entenderse como una aproximación a las actividades y, particularmente, a la investigación urbanística y arquitectónica que se pueda producir en el campo universitario en sinergia ...

RNA m1A methyltransferase TRMT61A promotes colorectal tumorigenesis by enhancing ONECUT2 mRNA stability and is a potential therapeutic target

open access: yesCancer Communications, EarlyView.
Abstract Background The role of N1‐methyladenosine (m1A) in cancer is poorly understood. Here we explored the function of RNA methyltransferase TRNA methyltransferase 61A (TRMT61A) in colorectal cancer (CRC) and its potential as a therapeutic target. Methods RNA m1A levels were assessed through liquid chromatography‐mass spectrometry.

Sustainable One‐Pot Synthesis of N‐Substituted Pyrroles Using a Multifunctional Cobalt‐Based Catalyst

open access: yesChemCatChem, EarlyView.
The one‐pot synthesis of N‐substituted pyrroles from nitrobenzene and 2,5‐hexanodione is first ever reported with >99% conversion and >99% chemoselectivity, in a green solvent, using a non‐noble metal‐based catalyst and hydrogen as a reductant under mild reaction conditions simultaneously.

Modulation of the Acidity of HY, HBETA, and HZSM‐5 Zeolites by Lanthanum Incorporation for Selective Gasoline Desulfurization in the FCC Riser

open access: yesChemCatChem, EarlyView.
Desulfurization in the FCC riser is achieved by modifying zeolite catalysts with La3+ ions, promoting H2S formation from thiophenic compounds while suppressing secondary reactions. This approach enhances gasoline quality by increasing selectivity for H2S and enabling efficient condensation and alkylation, supporting cleaner fuel production and ...

Evidences of the Stabilization for Weeks of the Benzyl Cation in Zeolites

open access: yesChemistryEurope, EarlyView.
The benzyl cation is plausibly formed inside zeolites after rearrangement of individually isolated tropylium cations at room temperature. The benzyl cation–entrapped zeolite is stable for weeks without any storage precaution, and a solid–state 13C nuclear magnetic resonance spectrum of this iconic carbocation could be recorded.
