PEAD/PEBDL Composites - Evaluation of the Exfoliation of Organophilic Clay Using the Nielsen Model and of the Mechanical, Optical and Permeability Properties
(Assoc Brasil PolimerosSao CarlosBrasil, 2010)
Composite and bi-layer films based on gelatin and chitosan
(Elsevier, 2009-02)
The aims of this work were: to develop composite, bi-layer and laminated biodegradable films based on gelatin and chitosan, to determine film barrier and mechanical properties and to characterize their microstructure. ...
Different oxides used as diffusion barriers in composite hydrogen permeable membranes
(Elsevier Science, 2006-04)
Composite Pd-Ag membranes supported on modified porous stainless steel substrates were prepared by sequential electroless plating. To improve the stability of the Pd-Ag alloy, two different intermediate layers of α-Fe2O3 ...
Effects of intergranular barrier fluctuations on the electrical conductivity of polycrystalline semiconductors
(Elsevier Science, 2018-11-15)
We studied the influence of intergranular barrier fluctuations on the electrical response of 3D semiconductor polycrystals. We first computed with a numerical simulation model the dispersion in the intergranular barrier ...
Gas permeability of bentonite barriers: development, construction and testing of a measurement system

Electroconvective flow induced by dielectric barrier injection in silicone oil
(Elsevier, 2013-01)
It has been demonstrated that dielectric barrier actuators can be used to induce electrohydrodynamics flows in air as well as in gas. These actuators are often called surface non-thermal plasma actuators in gas applications. ...
