Effect of poling state of piezoelectric poly(vinylidene fluoride) films on C2C1...

[Excerpt] Skeletal muscles, comprising between 40-45% of an adult human body mass, are responsible for generating voluntary movement, postural support, breathing and locomotion. Severe injuries resulting in a muscle mass loss can lead to extensive and irreversible loss of muscle function [1]. In this sense, tissue engineering (TE) and regenerative medicine are growing fields of interest due to promising results...

Isomerisation of pinene oxide in the presence of an indenyl Molybdenum carbonyl...

Generative solutions: adaptation and flexibilization in housing as a qualified ...

Housing for all is back on the international agenda. The economic crisis forces researchers and architects to rethink the concept of living and adopt more flexible housing design strategies as an alternative to typologies that impose rules of coexistence and do not reflect the social dynamics of a community. The introduction of rules-based housing design strategies allows the implementation of more dynamic proc...

Application of an Indenyl Molybdenum Dicarbonyl Complex in the Isomerisation of...

The complex [{(Z5-Ind)Mo(CO)2(m-Cl)}2] (1) has been tested for the industrially relevant catalytic isomerisation of a-pinene oxide (PinOx) to campholenic aldehyde (CPA) in the liquid phase. PinOx conversion and CPA selectivity are strongly influenced by the solvent employed. Complete conversion of PinOx was achieved within 1 min at 55 1C or 30 min at 35 1C using 1,2-dichloroethane as solvent, giving CPA in 68% ...

Isomerization of alfa-pinene oxide in the presence of indenyl allyl dicarbonyl ...

The indenyl complexes IndM(η3-C3H5)(CO)2 (M=Mo (1), W (2)), (IndMe)Mo(η3-C3H5)(CO)2 (3) and (IndSiMe3)Mo(η3-C3H5)(CO)2 (4) display catalytic activity for the isomerisation of α-pinene oxide. Conversion reached 97% after 3 h at 35 °C in the presence of 1 and 1,2-dichloroethane as solvent, giving campholenic aldehyde in 56% yield. Solvent polarity and basicity appear to affect the reaction rate. Whereas the type ...

Molybdenum(II) Diiodo-Tricarbonyl Complexes Containing Nitrogen Donor Ligands a...

The molybdenum(II) tricarbonyl complexes [Mo(CO)3I2L n ] (n = 1, L = 2,2′-bipyridine, 4,4′-di-tert-butyl-2,2′-bipyridine; n = 2, L = pyridine, 4-tert-butylpyridine) have been examined as catalyst precursors for the epoxidation of the biorenewable olefin methyl oleate with tert-butylhydroperoxide. In situ oxidative decarbonylation of the precursors gives highly active and selective molybdenum(VI) catalysts, whic...

Molybdenum(VI) Catalysts obtained from eta3-Allyl Dicarbonyl Precursors: Synthe...

The oxidative decarbonylation of the η3-allyl dicarbonyl complexes [Mo(η3-C3H5)Cl(CO)2(L)] (L = 2,2′- bipyridine (bipy) (1), 4,4′-di-tert-butyl-2,2′-bipyridine (di-tBu-bipy) (2)) by reaction with aqueous tertbutylhydroperoxide (TBHP) or H2O2 gave the following compounds in good to excellent yields: the oxobridged dimers [MoO2Cl(L)]2O (L = bipy (3), di-tBu-bipy (6)) using TBHP(10 equiv.)/CH3CN/r.t.; the molybden...

Development of dioctadecyldimethylammonium bromide/monoolein liposomes for gene...

The artificial introduction of nucleic acids (NA) into mammalian cells (transfection) has become, in recent years, a well-established procedure in basic and applied research, which allowed the study of gene function and regulation. The advances in this area have made possible the use of these methods for gene-based medicines, which constitute alternative therapeutic approaches. One of the most prominent methods...

Oxido-bis¬[chlorido(4,4'-di-tert-butyl-2,2'-bipyridine-2N,N')dioxido¬molybdenum...

The title hydrate, [Mo2Cl2O5(C18H24N2)2]·0.2H2O, has been isolated as the oxidation product of [Mo(3-C3H5)Cl(CO)2(di-t-Bu-bipy)] (where di-t-Bu-bipy is 4,4'-di-tert-butyl-2,2'-bipyridine). A -oxide ligand bridges two similar MoCl(di-t-Bu-bipy)O2 units, having the terminal oxide ligands mutually cis, and the chloride and -oxide trans to each other. In the binuclear complex, the coordination geometries of the met...

Tailoring elastase inhibition with synthetic peptides

Chronic wounds are the result of excessive amounts of tissue destructive proteases such as human neutrophil elastase (HNE). The high levels of this enzyme found on those types of wounds inactivate the endogenous inhibitor barrier thus, the search for new HNE inhibitors is required. This work presents two new HNE inhibitor peptides, which were synthesized based on the reactive-site loop of the Bowman–Birk inhibi...
