Regioselective ring opening and isomerization reactions of 3,4-epoxyesters catalyzed by boron trifluoride
(American Chemical Society, 2011)
Efficient ring opening of 3,4-epoxyesters with alcohols to produce 4-alkoxy-3-hydroxyesters and their isomerization into 4-ketoesters using boron trifluoride as the catalyst are presented. Both transformations are simple ...
Impact of the Warhead of Dipeptidyl Keto Michael Acceptors on the Inhibition Mechanism of Cysteine Protease Cathepsin L
(American Chemical Society, 2023-10-03)
Cathepsin L (CatL) is a lysosomal cysteine protease whose activity has been related to several human pathologies. However, although preclinical trials using CatL inhibitors were promising, clinical trials have been ...
Structural and morphological studies of the dipeptide based L-Pro-L-Val organocatalytic gels and their rheological behaviour
(Royal Society of Chemistry, 2012-07)
Organocatalytic gels based on the dipeptide sequence L-Pro-L-Val have been studied by two different FTIR techniques. This suggests a different arrangement of the gelator molecules in the self-assembled fibers depending on ...
Vibrational Circular Dichroism Shows Reversible Helical Handedness Switching in Peptidomimetic l-Valine Fibrils
(American Chemical Society, 2012)
We elucidate the supramolecular organization in the form of microsize fibrils of gels formed by a l-Valine peptidomimetic compound. Analysis was based on circular dichroism spectroscopies, vibrational (VCD) and electronic ...
Dual Catalysis with an IrIII–AuI Heterodimetallic Complex: Reduction of Nitroarenes by Transfer Hydrogenation using Primary Alcohols
(Wiley, 2012-05)
A triazolyl-di-ylidene ligand has been used for the preparation of a homodimetallic complex of gold, and a heterodimetallic compound of gold and iridium. Both complexes have been fully characterized and their molecular ...
Selective and highly efficient dye scavenging by a pH-responsive molecular hydrogelator
(Royal Society of Chemistry, 2010)
A structurally simple low molecular weight hydrogelator derived
from isophthalic acid forms robust pH-responsive hydrogels
capable of highly efficient and selective dye adsorption.
EuIII-Doping of Lamellar Bilayer and Amorphous Mono-Amide Cross-Linked Alkyl/Siloxane Hybrids
(Wiley-VCH, 2010)
Two structurally different but chemically similar families of alkyl/siloxane mono-amidosil hosts, represented by m-A(x) [where x = 14 or 8 represents the number of CH2 groups of the pendant alkyl chains directly bonded to ...
Residence time distribution, a simple tool to understand the behaviour of polymeric mini-flow reactors
(Royal Society of Chemistry, 2012-09)
A simple method for the determination of the residence time distribution (RTD) of different polymer-based mini-flow reactors has been developed. The flow patterns have been adjusted employing the axial dispersion model, ...
Solid solutions of mixed metal Mn3−xMgxFe4(PO4)6orthophosphates: colouring performance within a double-firing ceramic glaze
(Elsevier, 2011-03)
Solid solutions of mixed metal Mn3−xMgxFe4(PO4)6 orthophosphates (x = 0, 0.5, 1, 1.5, 2, 2.5, and 3) were prepared for the first time (from coprecipitate powders calcined up to 1000 °C) and characterized by thermal analysis, ...
Quantum dot–polymethacrylate composites for the analysis of NOx by fluorescence spectroscopy
(Elsevier, 2012)
A new type of hybrid materials composed by core–shell (CdSe/ZnS) quantum dots adsorbed on polymethacrylate surfaces has been synthesized and characterized, specially by means of time-resolved fluorimetry. The ability of ...
