Resin Bonding to a Feldspar Ceramic After Different Ceramic Surface Conditioning Methods: Evaluation of Contact Angle, Surface pH, and Microtensile Bond Strength Durability
(Quintessence Publishing Co Inc, 2011-12-01)
Purpose: To evaluate the surface pH, contact angle and microtensile bond strength (MTBS) of a resin-cement to feldspathic ceramic after various surface conditioning methods (SC).Materials and Methods: For pH measurements, ...
Treatment of PET and PU polymers by atmospheric pressure plasma generated in dielectric barrier discharge in air
(Elsevier B.V. Sa, 2010-06-25)
Plasma treatments are frequently employed to modify surface properties of materials such as adhesivity, hydrophobicity, oleophobicity etc. Present work deals with surface modification of common commercial polymers such as ...
Hybrid nanocomposites containing carboxymethylcellulose and silver nanoparticles
(2013-03-01)
Silver nanoparticles have high temperature stability and low volatility, and at the nanoscale are known to be an effective antifungal and antimicrobial agent. The present investigation involves the synthesis of silver ...
Biodegradation of a polylactic acid/polyvinyl chloride blend in soil
(Wiley-Blackwell, 2012-07-05)
This study investigated the microbial action in soil on poly(L-lactic acid) (PLLA) and polyvinyl chloride (PVC) films and a PLLA/PVC 7 : 3 blend, using Fourier transform infrared spectroscopy (FTIR), contact angle and ...
Detection of Sourgrass (Digitaria insularis) Biotypes Resistant to Glyphosate in Brazil
(Weed Sci Soc Amer, 2011-04-01)
Sourgrass is a perennial weed infesting annual and perennial crops in Brazil. Three biotypes (R1, R2, and R3) of sourgrass suspected to be glyphosate-resistant (R) and another one (S) from a natural area without glyphosate ...
Surface Modification of Polycarbonate by Atmospheric-Pressure Plasma Jets
(Institute of Electrical and Electronics Engineers (IEEE), 2012-11-01)
Plasmas have been frequently employed to modify material surface properties; however, many of these processes are not suitable for treating sensitive materials and biological objects that cannot withstand vacuum and/or ...
Reduction of bacterial adhesion to biocompatible polymer surfaces via plasma processing
(2011-12-01)
Plasma processing of the surfaces of biomaterials is interesting because it enables modification of the characteristics of a surface without affecting bulk properties. In addition, the results are strongly influenced by ...
