Bonding of silicone rubbers on metal (2) physical chemistry ofadhesion tIn the previous paper of this series, three primer formulations were tested for the adhesion of two differentgrades of silicone elastomer on aluminum studs. The simple approach consisting at analyzing primers’chemical composition was not suitable to generate a formulation allowing “universal” adhesion of siliconeelastomer on metal. In the second part of this series, we studied more specifically the properties of theprimer films (topology, thickness and roughness, surface energy) and of the ...

Topological data analysis: A promising big data exploration tool in biology, analytical chemistry and physical chemistry a b s t r a c tAn important feature of experimental science is that data of various kinds is being produced at an unprecedented rate. This is mainly due to the development of new instrumental concepts and experimental methodologies. It is also clear that the nature of acquired data is significantly different. Indeed in every areas of science, data take the form of always bigger tables, where all but a few of the columns (i.e. variables) turn out to be ...

Comparison between performances of poly acryl amide as poly coagulant with mineral coagulants in two pre-treatment reactors on the effluent wastewater from desalination units of Mobin Petrochemical complexAbstractThe performance assessment of poly acryl amide and mixtures of it (10 and 15 gr/lit) which contain mineral coagulants (5, 10, 15 and 20 mg/lit) as auxiliary coagulants in pretreatment of petrochemical wastewater is considered, in this pilot scale experimental work. Major parameters in coagulation and flocculation such as total hardness, turbidity,amount of ...
