Waste and agricultural residues offer significant potential for harvesting chemical energy with simultaneous reduction of environmental pollution, providing carbon neutral (or even carbon negative) sustained energy production, energy security and alleviating social concerns associated with the...

Hydrogen production based in the corrosion of light metals in water solutions is an interesting alternative. Among all of them, Mg is probably the most adequate metal for energetic purposes due to its high electron density and oxidation potential. A safe and environmental-friendly method of...

This study reports the development of a new system of IL (ionic liquid) with metal complex, chemically crosslinked, electrospun nanofibers based on PVDF (poly(vinylidene fluoride)) as a polymer matrix. The nanofibers were fabricated with different amounts of ionic liquid, PEG (polyethylene...

In this work, the layered compound of LiCo0.525Ni0.475O2, (LCNO) was prepared by self-propagating combustion reaction for the cathode of lithium-ion battery. We used self-propagating combustion reaction to prepare the compound of LiCo0.525Ni0.475O2, (LCNO) as a cathode material of lithium-ion...

In this paper, the morphology, chemical composition and reactivity of MCM-48 powders impregnated with Ni, Mo or both toward hydrodesulphurization (HDS) of thiophene were characterized. The reactivity of the catalyst was quantitatively compared with a standard industrial catalyst (from...

A non-linear model for time-dependent occupation of lattice gas sites is studied. A self-consistent approximation for the diffusion operator is proposed and studied in discrete and continual forms. It is shown that self-organization effects in the spinodal region lead to a spontaneous...

A simple hydrothermal growth process was developed to deposit conformal manganese oxide nanospheres with a diameter of 10 to 20 nm on mesoporous carbon paper. The coating of nanospheres increased the cyclic-voltammogramic response of carbon paper by a factor of 5 with a slight dependence on the...
