Films of biodegradable blends polycaprolactone (PCL) and Pluronics F68 F127 were manufactured by an industrial thermo-mechanical process to be applied as potential delivery systems. The effects on the structure (mesophase organization), thermal mechanical properties investigated using differential scanning calorimetry (DSC), small-angle X-ray scattering (SAXS), diffraction (XRD), polarized optical microscopy (POM) tensile tests. addition affected crystallization changing relative amounts...
Nanostructured fluids containing anionic surfactants are among the best performing systems for cleaning of works art. Though efficient, their application may result in formation a precipitate, due to combination with divalent cations that might leach out from artifact. We propose here two new aqueous formulations based on nonionic surfactants, which non-toxic, readily biodegradable and insensitive presence ions. The properties water–nonionic surfactant–2-butanone (MEK) were assessed both...
Complex fluids composed of water, an organic solvent, and a surfactant have been recently employed as cleaning systems to remove hydrophobic materials, such polymeric coatings, from solid surfaces. The simultaneous presence surfactants solvent with good affinity for the polymer was proven necessary polymer's removal, but comprehension mechanism is poorly understood. In this Article, we investigated highlighting specific role each component in interaction film. particular, results quartz...
Complex fluids based on amphiphilic formulations are emerging, particularly in the field of conservation works art, as effective and safe liquid media for removal hydrophobic polymeric coatings. The comprehension cleaning mechanism is key to designing tailored this purpose. However, interaction between nanostructured polymer films still poorly understood. In study, we show how combination confocal laser scanning microscopy (CLSM) atomic force (AFM) provides interesting complementary insight...
Abstract The cleaning of artifacts must not alter the original properties objects. While use free solvents is risky, their confinement into polymeric networks can allow safe removal unwanted layers from artifacts. Recently, a methyl 2-methylprop-2-enoate (MMA)-based organogel was formulated as loaded with butan-2-one (MEK), and used to remove aged varnishes canvas paintings. However, this formulation enough retentive its on paper, where higher retentiveness needed avoid uncontrolled...
In this work, carbon black (CB) is added in small amounts (3–10% w/w) to green aqueous dispersions based on sodium oleate, guar gum, hyaluronate, or hydroxypropyl cellulose gels enhance their stability against mechanical and thermal stresses provide electric responsiveness an external voltage. Rheology, optical microscopy, angle X-ray scattering, conductivity measurements are performed compare the properties of CB-enriched formulations those pristine dispersions. Our results demonstrate that...
The Natural History Museum of Florence, and in particular "La Specola", houses several ceroplastics collections produced Florence the XVIII-XIX centuries by Clemente Susini co-workers. include models fruits plants, vertebrate invertebrate animals, over 1400 anatomical waxes. All are mainly constituted beeswax. Although extremely resistant, undergo a wide range degradation processes. Periodically, white crystalline efflorescence, commonly called "wax bloom", appears on surface objects...
The addition of azorubine to a viscoelastic aqueous dispersion sodium oleate (NaOL, 0.43 M, 13% w/w) and KCl (up 4% leads green gel-like system whose rheological behavior can be efficiently reversibly triggered from remote by using UV light. Rheology, Differential Scanning Calorimetry (DSC) measurements phase studies indicate that the original texture NaOL is significantly hardened upon irradiation for 8 hours in presence azorubine, showing seven hundred-fold increase viscosity. treatment...
Abstract Pharmacological chaperones (PCs) can restore correct enzymatic activity at sub‐inhibitory concentrations and are considered an emerging therapy for Gaucher Disease (GD). Amphiphilic PCs show more favourable cross‐membrane properties have a higher on cells than hydrophilic PCs. To investigate whether the biological of amphiphilic iminosugars is related to their state as monomers or micellar aggregates, we synthesized some novel N ‐alkylated performed physico‐chemical...
