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 ...
Morphological modifications and surface amorphization in ZnO sonochemically treated nanoparticles
(2013-05-01)
Application of nanoscale materials in photovoltaic and photocatalysis devices and photosensors are dramatically affected by surface morphology of nanoparticles, which plays a fundamental role in the understanding of the ...
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 ...

Effect of Ball Milling Treatment on Thermal, Structural, and Morphological Properties of Phosphated Starches from Corn and Pinhão
(2020-03-01)
In the previous study, the effect of chemical modification with sodium tripolyphosphate on the properties of corn and pinhão starches was evaluated. However, physical modifications also confer specific characteristics on ...
Surface morphology and structural modification induced by femtosecond pulses in hydrogenated amorphous silicon films
(Amer Scientific Publishers, 2015-03-01)
This work investigates the modification, resulting from fs-laser irradiation (150 fs, 775 nm and 1 kHz), on the structure and surface morphology of hydrogenated amorphous silicon (a-Si:H) thin films. The sample morphology ...
Electromyographical, ultrasonographical and morphological modifications in semitendinous muscle after transposition as ventral perineal muscle flap
(Blackwell Publishing, 2005-09-01)
The aim of this study was to evaluate modifications occurring in semitendinous muscle after transposition as a ventral perineal muscle flap using electromyography, ultrasonography, and morphological studies. Ten male ...

Dental implants: Surface modification of cp-Ti using plasma spraying and the deposition of hydroxyapatite
(2003-03-13)
The commercial pure titanium (cp-Ti) is currently being used with great success in dental implants. In this work we investigate how the cp-Ti implants can be improved by modifying the metal surface morphology, on which a ...
