1,7-Naphthodiyne: a new platform for the synthesis of novel, sterically congested PAHs
(Royal Society of Chemistry, 2016-03-17)The synthesis of an efficient precursor of the novel 1,7-naphthodiyne synthon is reported. Preliminary experiments demonstrate the usefulness of this platform for the synthesis of sterically congested polyarenes, such as ... -

10,000 years of climate control over carbon accumulation in an Iberian bog (southwestern Europe)
(Elsevier, 2019)The northwest region of the Iberian Peninsula is home to a unique ecosystem of bogs, which are particularly sensitive to projected climate change. In this context, the rate of carbon (C) accumulation in Chao de Veiga Mol, ... -

14N NMR spectroscopy study of binding interaction between sodium azide and hydrated fullerene
(MDPI, 2017)Our study is the first attempt to study the interaction between NaN3 and hydrated fullerenes C60 by means of a non-chemical reaction-based approach. The aim is to study deviations of signals obtained by 14N NMR spectroscopy ... -
18F-florbetapir PET as a marker of myelin integrity across the Alzheimer’s disease spectrum
(Springer, 2022)Purpose: Recent evidence suggests that PET imaging with amyloid-β (Aβ) tracers can be used to assess myelin integrity in cerebral white matter (WM). Alzheimer’s disease (AD) is characterized by myelin changes that are ... -
1D alignment of proteins and other nanoparticles by using reversible covalent bonds on cyclic peptide nanotubes
(Royal Society of Chemistry, 2021)Self-assembling cyclic peptide nanotubes are supramolecular structures whose diameter and external surface properties are precisely controlled. In this communication we describe a general strategy to align different molecules ... -
1D to 2D Self Assembly of Cyclic Peptides
(American Chemical Society, 2020)Despite recent developments in two-dimensional self-assembly, most supramolecular 2D materials are assembled by tedious methodologies, with complex surface chemistry and small sizes. We here report d/l-alternating cyclic ... -
(1RS,4RS,5RS)-Methyl 2-(3,5-dinitrobenzoyl)-2-oxa-3-azabicyclo[3.3.0]oct-7-ene-4-carboxylate
(International Union of Crystallography, 2009)In organic synthesis, the usual techniques as NMR, mass or infra-red spectrometry and elemental analysis are often not enough for the unequivocally determination of a structure of a compound. When it is possible to ... -

[2+1] Cycloaddition of Catalytic Ruthenium Vinyl Carbenes: A Stereoselective Controlled Access to (Z)- and (E)-Vinyl Epoxypyrrolidines
(American Chemical Society, 2016)Aza-alkynals undergo a cyclization reaction with diazo compounds in the presence of catalytic amounts of Cp*RuCl(cod) to afford vinyl epoxypyrrolidines, valuable building blocks for the synthesis of biologically active ... -
O 2-(3’-Hidroxi-2’-Piridil)Bencimidazol como sonda fluorescente para o estudo de reaccións de trensferencia protónica fotoinducida
(2017)A cuantiosa presenza de procesos de transferencia protónica en sistemas químicos e biolóxicos, fan do estudo da súa dinámica o obxecto de numerosas liñas de investigación actuais, especialmente centradas no emprego de ... -
A 2-transcript host cell signature distinguishes viral from bacterial diarrhea and it is influenced by the severity of symptoms
(Nature Publishing Group, 2018)Recently, a biomarker signature consisting of 2-transcript host RNAs was proposed for discriminating bacterial from viral infections in febrile children. We evaluated the performance of this signature in a different disease ... -
