Abstract: The present invention provides the compound LiMn2--x-yNaxMyO4/Na1-zMnLizMtO2/Na2CO3, to be used as a positive electrode for rechargeable lithium ion battery, where M is a metal or metalloid, 0.0?x?0.5; 0.0?y?0.5; 0.1?z?0.5; 0.0?t?0.3; as well as the method for producing it. The synthesis process includes disolving or mixing the precursor metals and then calcining them in air or controlled atmosphere in a temperature range between 250° C. and 1000° C., and for a time range of 0.5 h to 72 h to obtain the composite proposed with the interaction of its three present phases, presenting a high retention capacity during repeated loading/unloading cycles and excellent discharge capacity both at room temperature and up to 55° C.

Abstract: A positive electrode of an active material of interconnected polycrystalline and porous particles for secondary battery has been developed to achieve greater diffusion, excellent specific capacity and life cycle. The active material of the positive electrode for secondary battery is obtained from a hot-pressing process to which the composite fiber membrane is subjected with the precursors of the active metals and the polymer, obtaining morphologies such as monocrystalline particles, two-dimensional plates, and bars.

Abstract: A method that allows storage, transport and delivery of fungal propagules in a polymer matrix corresponding to microfibers or nanofibers that carry totally or partially encapsulated propagules infectious between fibrous sheets or adhered on their surface with applications in different inoculation strategies in the field of agriculture, horticulture, forestry, ecological remediation, and related areas.

Abstract: The present invention is based on the application of heating resistors by a temperature regulation circuit in certain points of the catalyzer so that this comes into operation in the least time possible, reducing most of the amount of low molecular stability or environmentally harmful substances. Likewise, little tumult are added to each monolith duct to raise exhaust gas turbulence and increase the contact between the reduction and oxidation agent, whether it be platinum, palladium and rhodium.
