In times of rethinking production processes and consumption habits to minimize the effects of global warming, it is crucial to find alternatives that lead to replacing fossil fuels by renewable materials. The development ...

New estimates are derived for the overall properties of linear solids with pointwise heterogeneous local properties. The derivation relies on the use of ‘comparison solids’ which, unlike comparison solids considered ...

Commercially pure grade 2 titanium in sheet form was processed by equal channel angular sheet extrusion (ECASE) up to two passes at room temperature. The ECASE process generated a heterogeneous state of deformation, mainly ...

In this work was investigated the catalytic potential of a new heterogeneous catalyst of stoichiometry Ca0.5K0.5TiCu0.25O3, with double perovskite structure, in the preparation of biodiesel via ethylic route. The catalyst ...

In the present article, kinetics of the photocatalytic oxidation (PCO) of nitric oxide (NO, as a typical air pollutant) is addressed. An extended Langmuir-Hinshelwood reaction rate model is proposed to describe the PCO of ...
