Impact of the surface hydrophobicity/hydrophilicity ratio on the catalytic properties of Ni nanoparticles/MCM-41 system used in the hydrogenation of acetophenone
(Elsevier Science, 2021-07-11)
Three nickel catalysts were prepared supporting pre-synthetized monodisperse Ni nanoparticles of 16 nm. As support, nanospheres of MCM-41 were used. Two batches of these supports were superficially modified by silylation ...
Adhesion study of cultured human lens capsule cells on hydrophilic intraocular lenses coated with polyethylene glycol
(Elsevier B.V., 2015-07-01)
PURPOSE: To evaluate the adhesion of human lens capsule cells on hydrophilic acrylic intraocular lenses (IOLs) coated with polyethylene glycol (PEG). SETTING: Department of Ophthalmology, Faculty of Medicine, Universidade ...
Primary and Secondary Stability of Implants with Hydrophilic Surfaces in the Posterior Maxilla: A Split-Mouth Randomized Controlled Clinical Trial
(2021-01-01)
Purpose: The aim of this split-mouth randomized clinical trial was to evaluate the primary and secondary stability of implants with hydrophilic surfaces in comparison to implants with conventional surfaces in the posterior ...
Chemical functionalization of polyamide 6.6 fabrics
(Elsevier Science BvAmsterdamHolanda, 2013)
Identification of cytoplasmic soluble antigens related to the major surface antigens of Leishmania braziliensis braziliensis and L. donovani chagasi
(Parasitol Res., 1990)
Abstract. This study describes the identification of aqueous-soluble antigens in Leishmania promastigotes immunologically and biochemically closely related to the major surface antigen. Proteins from surface-iodinated L. ...

Improvement of Cr-Co-Mo membrane surface used as barrier for bone regeneration through UV photofunctionalization: An in vitro study
(MDPI AG, 2017-07)
Although there are several studies of the ultraviolet (UV) light-mediated photofunctionalization of titanium for use as implant material, the underlying mechanism is not fully understood. However, the results of in vitro ...
Hydrophilization of PVC surfaces by argon plasma immersion ion implantation
(Kluwer Academic/plenum Publ, 2003-03-01)
Commercial polyvinylchloride (PVC) sheets were treated by plasma immersion ion implantation, PIII. Samples were immersed in argon glow discharges and biased with 25 kV negative pulses. Exposure time to the bombardment ...
Surface Morphological Modification of Crosslinked Hydrophilic Co-Polymers by Nanosecond Pulsed Laser Irradiation
(Elsevier Science, 2016-04)
This work reports an investigation of the surface modifications induced by irradiation with nanosecondlaser pulses of ultraviolet and visible wavelengths on crosslinked hydrophilic co-polymeric materi-als, which have been ...
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 ...
