Use of Saponins as an Effective Surface Modifier in Cellulose Nanocomposites
(Taylor & Francis Ltd, 2012-01-01)
The present paper deals with the extraction of saponins from the pericarp of Sapindus mukorossi to use as compatibilizer in nanocomposites. The nanofibrils extracted from banana fibres are utilized as reinforcement of ...

Time-dependent induced potentials in convoy electron emission
(Elsevier Science, 2006-12)
We study the time-dependent induced potentials at the convoy electron position due to the self-interaction with a metal surface and to the shock wave created by the positive hole (vacancy) left. The time evolution of these ...
Enhancing pavement surface macrotexture characterization by using the effective area for water evacuation
(2016)
Adequate macrotexture characterization is an essential objective for transportation practitioners because primary pavement surface characteristics like friction, tire-pavement noise, splash and spray, and rolling resistance ...
Size and surface effects in the magnetic order of CoFe2O4 nanoparticles
(Elsevier Science, 2015-03)
In this work, we have focused on the size dependence of the magnetic properties and the surface effects of CoFe2O4 nanoparticles synthesized by high-temperature chemical method with diameter d~2, 4.5, and 7 nm, with narrow ...
Effect of temperature on the viscosity of cationic micellar solutions in the presence of added salts
(1987)
The effect of temperature on the viscosities of cetyltrimethylammonium salts (CTA X, X =Br-, NO3-, Tosylate) in the presence of added salts is presented. It was found that plots of 1n of relative viscosity vs 1/T was linear ...
