Study of polypropylene surface modification by air dielectric barrier discharge operated at two different frequencies
(2012-10-18)
In this work, air dielectric barrier discharge (DBD) operating at the line frequency (60 Hz) or at frequency of 17 kHz was used to improve the wetting properties of polypropylene (PP). The changes in the surface hydrophilicity ...
Silica deposition on zirconia via room-temperature atomic layer deposition (RT-ALD): Effect on bond strength to veneering ceramic
(2022-05-01)
Purpose: To develop and to characterize a hybrid interface between yttria-stabilized zirconia (Y-TZP) transformed layer and silica-based nanofilm to enable a better bonding between Y-TZP and a veneering ceramic. Material ...

Modificação superficial do tecido de malha de ácido polilatico (PLA) por tratamento plasma
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia MecânicaTecnologia de Materiais; Projetos Mecânicos; Termociências, 2013-08-08)
Some fibrous materials, for having properties such as biocompatibility, strength
and flexibility, are of great interest for medical and pharmaceutical applications.
Among these materials, the fabric made from polylactic ...
Facile photocatalytic immobilization strategy for P-25 TiO2 nanoparticles on low density polyethylene films and their UV-A photo-induced super hydrophilicity and photocatalytic activity
(Elsevier Science, 2020-08)
Immobilization of TiO2-P-25 nanoparticles on low-density polyethylene films (LDPE) was successfully achieved through a simple and facile photocatalytic procedure leading to the polymer surface functionalization (generating ...
Polymorphism, crystallinity and hydrophilic-lipophilic balance of stearic acid and stearic acid-capric/caprylic triglyceride matrices for production of stable nanoparticles
(ELSEVIER SCIENCE BV, 2011)
There is an increasing interest in lipid nanoparticles because of their suitability for several administration routes. Thus, it becomes even more relevant the physicochemical characterization of lipid materials with respect ...
Hydrophile-lipophile balance (HLB) of n-alkane phosphonic acids and theirs salts
(Elsevier Science, 2008-03-05)
As a previous step in their application as emulsifiers, here we performed a study of the hydrophile-lipophile balance (HLB) properties of decyl (C10H21PO3H2), dodecyl (C12H25PO3H2), tridecyl (C13H27PO3H2) phosphonic acids ...
