Photonics of fungal cell wall
(Cornell University, 2021-04-22)
The cell wall serves as a mechanical protection for the fungi and controls the traffic of molecules entering the cell. However, the optical role of the cell wall has not been fully investigated. In this work, we use a ...
Short- and long-time diffusion and dynamic scaling in suspensions of charged colloidal particles
(American Institute of Physics, 2018-04-03)
We report on a comprehensive theory-simulation-experimental study of collective and self-diffusion in concentrated suspensions of charge-stabilized colloidal spheres. In theory and simulation, the spheres are assumed to ...
Modeling of disorder effects and optical extinction in three-dimensional photonic crystals
(American Physical Society, 2009-12)
We present three different methods for the modeling of disorder effects in three-dimensional photonic crystals. In order to reproduce experimental results, we apply a method based on a statistical distribution of sphere ...
A unique ionic liquid with amphiphilic properties that can form reverse micelles and spontaneous unilamellar vesicles
(Wiley VCH Verlag, 2012-12)
Catanionic surfactants: The synthesis of a new surfactant ionic liquid with unique properties is described. The formation of reverse micelles in benzene and large unilamellar vesicles, formed spontaneously without the help ...
Structural colour in Tersina viridis
(Sociedad Espanola de Optica, 2017-10)
The colour of birds' plumage is due to the presence of pigments as well as to frequency selective structural effects produced by the interaction of light with the photonic microstructure that constitutes the feather barbs. ...
Structural characterization of nanoemulsions stabilized with sodium caseinate and of the hydrogels prepared from them by acid-induced gelation
(Elsevier, 2020-04)
Hydrogels obtained by acidification with glucono-δ-lactone (GDL), starting from nanoemulsions formulated with different concentrations of sodium caseinate (1–4 wt%) or 4 wt% sodium caseinate and sucrose (2–8 wt%), were ...
Erythrocyte Senescent Markers by Flow Cytometry
(Scientific Research, 2019-06)
Background: Mature red blood cells lack protein synthesis and are unable to restore inactivated enzymes, damaged cytoskeleton and membrane proteins. An oxidation breakdown of band 3 is probably part of the mechanism leading ...
On the relationship between pH-dependent β-lactoglobulin self assembly and gelation dynamics
(Universiti Putra Malaysia. Faculty of Food Science & Technology, 2018-04)
There are a lot of works in literature about the size particle of β-lactoglobulin (β-lg) at different conditions and also about its rheological properties; however, there are not works which connect both results. The aim ...
In flow metal-enhanced fluorescence for biolabelling and biodetection
(Royal Society of Chemistry, 2020-09)
Escherichia colibacteria were determined by in flow cytometry with laser excitation and fluorescence detection applying ultraluminescent core-shell nanoparticles based on Metal Enhanced Fluorescence (MEF). Core-shell ...
Membrane adsorption or penetration differentially modulates β-galactosidase activity against soluble substrates
(Elsevier Science, 2002-01)
We investigated if in complex environments, like those where β-galactosidase activity is usually assayed, the kinetics of hydrolysis against soluble substrates could be modulated through enzyme-surface interactions. Kinetic ...
