Polarity studies of single polyelectrolyte layers in polyelectrolyte multilayers probed by steady state and life time doxorubicin fluorescence
(Elsevier, 2022-02)
Hypothesis: Polarity in polyelectrolyte multilayers (PEMs) may vary from the inner to the top layers of the film as the charge compensation of the layers is more effective inside the PEMs than in outer layers. Doxorubicin ...
Extension of a classic thin double layer polarization theory of colloidal suspensions to include the stagnant layer conductivity
(American Chemical Society, 2011-07)
A rigorous extension of the classic Dukhin-Shilov thin double layer polarization theory including the stagnant layer conductivity is presented. Precisely the same assumptions and approximations made in the original theory ...
Amperometric glucose biosensor based on layer-by-layer films of microperoxidase-11 and liposome-encapsulated glucose oxidase
(Elsevier B.V., 2014-04-01)
An important step in several bioanalytical applications is the immobilization of biomolecules. Accordingly, this procedure must be carefully chosen to preserve their biological structure and fully explore their properties. ...
Estudo de dimensionamento de filtro lento retrolavável de camada simples (areia) e dupla camada filtrante (areia e antracito).
(Universidade Federal de Santa MariaBrasilUFSMUFSM Frederico Westphalen, 2023-07-10)
Backwashed slow sand filtration (FLR) is an excellent alternative for treating supply water in rural areas, on a household scale or for small communities. The present study aims to dimension the already consolidated FLR ...
Effect of different mini-volume colloid centrifugation configurations on flow cytometrically sorted sperm recovery efficiency and quality using a computer-assisted semen analyzer
(Wiley Blackwell Publishing, Inc, 2018-02)
Straws of sex-sorted sperm are usually packaged at a low concentration (e.g., ~2.1 × 106 sperm/ml) and cost significantly more than unsorted conventional semen from the same sire. In order to maximize the efficiency of ...
Microencapsulation of pink pepper essential oil: Properties of spray-dried pectin/SPI double-layer versus SPI single-layer stabilized emulsions
(2019-11-20)
Microencapsulation by spray drying of hydrophobic materials, such as pink pepper essential oil (Schinus terebinthifolia Raddi), relies on the efficient stabilization of the oil-in-water emulsion to be dried. Association ...
Single-layer dichroic filters for multifrequency receivers at THz Frequencies
(IEEE, 2020)
In this work, we report the design, construction, and characterization of two free-standing single-layer frequency-selective surface structures to be used as dichroic filters in the THz range. Their spectral responses are ...
Single and Multi-Layered Core-Shell Structures Based on ZnO Nanorods Obtained by Aerosol Assisted Chemical Vapor Deposition
(Centro de Investigación en Materiales Avanzados, 2015)
Burning Graphene Layer-by-Layer
(Nature Publishing Group, 2015-06-23)
Graphene, in single layer or multi-layer forms, holds great promise for future electronics and high-temperature applications. Resistance to oxidation, an important property for high-temperature applications, has not yet ...
