Two styrene–bTwo styrene–butadiene–styrene block rubbers, one with 10wt% calcium carbonate filler (S6C), and one without (S6) were surface treated with UV radiation. The resulting surface modifications and adhesion properties with polyurethane adhesive were studied. The surface modifications produced on these…

Thermoplastic polyurethane (TPU) adhesives containing nanosilicas with different specific surface area and silanol group content were prepared and characterized by FTIR spectroscopy, differential scanning calorimetry (DSC), thermogravimetry (TGA), X-ray diffraction, plate-plate rheology, dynamical–mechanical–thermal analysis (DMTA), transmission electron microscopy (TEM), and…

The effect of adding Sn to Pt/CeO2–Al2O3 and Pt/Al2O3 catalysts was studied with X-ray photoelectron spectroscopy (XPS), 119Sn Mössbauer
spectroscopy, and adsorption microcalorimetry of CO at room temperature. Catalysts were reduced in situ at 473 (non-SMSI state) and 773 K

Two ethylene vinyl acetate (EVA) copolymers (12 and 20 wt% of vinyl acetate,VA,
content) have been treated with low pressure RF plasmas from non-oxidizing gases (Ar, N2) and oxidizing gases (air, a mixture of 4N2: 6O2 (v/v), O2 and CO2).…

A procedure to increase the adhesion of block styrene–butadiene–styrene (SBS) rubber consisting of the reactive grafting with maleic anhydride (MA) in the presence of an organic peroxide radical initiator is proposed. The influence of the reactive grafting on the surface…

Neurocysticercosis (NCC), which is caused by infection with the larval stage of the pork tapeworm (Taenia solium), is now recognized as a major cause of neurologic diseases in countries where the infection is endemic. Migration of persons from these countries…

The adoption of ISO 9000 has been justified in terms of the many benefits it generate, although problems may also arise. Such advantages and disadvantages lead to different reasons for seeking certification. Based on these reasons, this paper analyzed the…

Technological innovation requires a technical preparation in material, financial and human resources. However, without a clear corporate culture, the technical side of technological innovation will hardly develop in a satisfactory manner.
In this light, we analyze the origin of a…
