Clean enzymatic preparation of oxygenated biofuels from vegetable and waste cooking oils by using spongelike ionic liquids technology
(American Chemical Society, 2016)
The biocatalytic synthesis of oxygenated biofuels
(fatty acid solketal esters, FASEs) and biodiesel (fatty acid
methyl esters, FAMEs) was carried out by both the direct
esterification of fatty acids (i.e., lauric, ...
Ionic transport on composite polymers containing covalently attached and absorbed ionic liquid fragments
(Elsevier, 2016)
The ionic transport of five supported ionic liquid-like phases (SILLPs) based on 1-butyl imidazolium ion covalently attached to a polymeric matrix has been analysed by means of electrochemical impedance spectroscopy (EIS) ...
Synthesis and reactivity of phosphanide bridged 1,1´-bis(diphenylphosphino)ferroceno complexes [(RF)2Pt(µ-PPh2)2M(dppf)] [M= Pt,Pd]
(Elsevier, 2016-12)
Hetero-trinuclear complexes of formula [(C6F5)2Pt(μ-PPh2)2M(dppf)] [dppf = 1,1′-bis(diphenylphosphino)ferrocene, M = Pt (1), M = Pd (2)] were prepared by coupling between cis-[(C6F5)2Pt(PPh2)2]Li2 and cis-MCl2(dppf). ...
Site-selective symmetries of Eu3+-doped BaTiO3 ceramics: a structural elucidation by optical spectroscopy
(Royal Society of Chemistry, 2019-10-22)
Eu3+-Doped BaTiO3 ceramics with dopant contents between 0 and 10 mol% were prepared by sol–gel synthesis based on the nominal compositions (Ba1−3xEu2x)TiO3 and Ba(Ti1−xEux)O3−x/2, where two possible substitution mechanisms ...
Improvement in varistor properties of CaCu3Ti4O12 ceramics by chromium addition
(Elsevier, 2019-11-17)
The effect of chromium addition on the structure and electrical properties of CaCu3Ti4O12 is studied. Compositions based on the formula CaCu3Ti4-xCrxO12-δ (x = 0, 0.025, 0.050 and 0.075 mol%) are prepared by solid-state ...
Photoactive Hexanuclear Molybdenum Nanoclusters Embedded in Molecular Organogels
(American Chemical Society, 2019-07-05)
Hexanuclear molybdenum clusters are attractive species because of their outstanding photonic properties, and in the past they have been attached to a variety of supports such as organic polymers and inorganic nanoparticles, ...
Self-assembled multivalent (SAMul) ligand systems with enhanced stability in the presence of human serum
(Royal Society of Chemistry, 2019)
Self-assembled cationic micelles are an attractive platform for binding biologically-relevant polyanions such as heparin. This has potential applications in coagulation control, where a synthetic heparin rescue agent could ...
Synthesis of combretastatin A-4 O-alkyl derivatives and evaluation of their cytotoxic, antiangiogenic and antitelomerase activity
(Elsevier, 2013-12)
We here report the synthesis and biological evaluation of several combretastatin A-4 derivatives alkylated at the phenol hydroxyl group. Some of these derivatives contain an (E)-arylalkene fragment reminiscent of that ...
Stereoselective synthesis of a C1-C18 fragment of amphidinolides G and H
(Elsevier, 2013-04)
A stereoselective synthesis of a C1–C18 segment of the structure of the cytotoxic macrolides amphidinolides G and H is reported. The target compound was retrosynthetically disconnected into three fragments. In the synthetic ...
Synthesis and organogelating ability of bis-urea pseudopeptidic compounds
(Elsevier, 2013-03)
A large family of amphiphilic pseudopeptidic derivatives in which the aliphatic tails are connected to the pseudopeptidic moiety through urea functionalities have been prepared with excellent yields. The synthetic procedure ...
