Variation of Physical Properties of Rigid Polyurethane Foams Synthesized from Renewable Sources with Different Commercial Catalysts

The aim of this study is to investigate the effect on the physical and mechanical properties of four different types of mortars after exposure to a sulfuric acid attack: (i) a

These base stations were powered with renewable energy sources (wind, solar and geother- mal) and, in addition, equipped with batteries as well as connected to the traditional

In this work, we compare the conversion, selectivity and stability on-stream in continuous flow regime of lab-synthesized and commercial palladium and

Bimetallic Pt:Pd catalysts with different molar ratios and 0.5 wt% overall metal load supported on sulfated zirconia catalysts (SZ) were synthesized and tested in

The extension of light absorption of the synthesized catalysts into the visible range was probably resulting from the presence of the photocatalytic composite, iron..

This work is intended first to establish the suitability of VIS/NIR reflectance spectra and PLSR to study the influence of different physical–chemical properties of these

This work is the study of the chemical complexity and the physical conditions of the molecular gas in three galaxies with different type of activity, in our sample we have a

EC_T (total transport energy consumption, the sum of both renew- able and non-renewable sources) and TNR_T (total non-renewable energy con- sumption in the transport sector)
