Forward Osmosis is a promising strategy for desalination processes, however some aspects have to be better characterized make it competitive with other affirmed technologies. One of these the selection draw agent, i.e., polymeric solution that has fulfill different requirements guarantee both high membrane performances and good regeneration process. Previous studies identified thermoresponsive copolymer known as PAGB2000 potential agent. However, in open literature there no information on...
Using colloids effectively confined in two dimensions by a cell with thickness comparable to the particle size, we investigate nucleation and growth of crystallites induced locally heating solvent near-infrared laser beam. The particles, which are "thermophilic," move towards spot solely because thermophoresis no convection effects, forming dense clusters whose structure is monitored using order parameters that gauge local density orientational ordering. We find ordering takes place when...
We investigate the rheo-mechanical properties of Mebiol Gel®, a thermosensitive gel-forming polymer extensively used as medium for cellular culture, using passive microrheology made either by standard dynamic light scattering or photon correlation imaging. In dilute limit, displays Newtonian behavior with an effective viscosity that decreases temperature, consistent peculiar aggregation mechanism characterized increase molecular weight simultaneous reduction aggregate size. By increasing...
Self-assembling peptides (SAPs) have been increasingly studied as hydrogel-former gelators because they can create biocompatible environments. A common strategy to trigger gelation, is use a pH variation, but most methods result in change that too rapid, leading gels with hardly reproducible properties. Here, we the urea-urease reaction tune gel properties, by slow and uniform increase. We were able produce very homogeneous transparent at several SAP concentrations, ranging from c=1g/L...
Abstract The intrinsic heterogeneity of bacterial niches should be retained in vitro cultures to represent the complex microbial ecology. As a case study, mucin‐containing hydrogels ‐CF‐Mu 3 Gel ‐ are generated by diffusion‐induced gelation, bioinspired on cystic fibrosis (CF) mucus, and niche challenging current therapeutic strategies. At breathing frequency, CF‐Mu exhibits G ′ ″ equal 24 3.2 Pa, respectively. Notably, structural gradients with gradual reduction oxygen tension across its...
The weak absorption of a laser beam generates in fluid an inhomogeneous refractive index profile acting as negative lens. This self-effect on propagation, known Thermal Lensing (TL), is extensively exploited sensitive spectroscopic techniques, and several all-optical methods for the assessment thermo-optical properties simple complex fluids. Using Lorentz–Lorenz equation, we show that TL signal directly proportional to sample thermal expansivity α, feature allowing minute density changes be...
Photon correlation imaging unveiled gelation kinetics and stress relaxation in colloidal filamentous gels, set by perfusion of ions. We observed a linear-in-time evolution the front, ionic-strength dependant rearrangement dynamics.
Abstract A distinctive feature of the biological substrates hosting bacterial niches is their intrinsic heterogeneity, which should be retained in vitro cultures to closely represent complex microbial ecology. Here, we design and characterise 3D providing bacteria with environments that possess structural heterogeneity spontaneous microscopic dynamics. As a case study, generate by diffusion-induced gelation mucin-based hydrogel (CF-Mu 3 Gel) bioinspired on cystic fibrosis (CF) mucus, niche...
The Brownian dynamics of a colloidal particle is consistently modified by the presence in solvent other particles comparable size, whose effects on diffusion coefficient cannot be attributed to change effective viscosity. So far, despite their impact subjects ranging from microrheology phoretic transport crowded environments, detailed experimental survey these still lacking. By exploiting peculiar properties fluorinated particle, we have performed an extensive dynamic light scattering (DLS)...
