Methanol tolerant electrocatalysts for the oxygen reduction reaction
(Springer, 2015)
Direct methanol fuel cells (DMFCs) represent an interesting alternative in obtaining electricity in a clean and efficient way. Portable power sources are one of the most promising applications of passive DMFCs. One of the ...
Characterization of anodes for lithium ion batteries
(Springer, 2015-08-14)
The lithium-ion batteries are energy storage systems of high performance and low cost. They are employed in multiple portable devices, and these require the use of increasingly smaller and lighter batteries with high energy ...
Electrochemical characterization of MWCNT Ni(OH)2 composites as cathode materials
(Springer, 2015-09-04)
The hydrothermal method was used to synthesize multi-walled carbon nanotube/nickel hydroxide composites (MWCNT/Ni(OH)2). The structure and morphology of the prepared materials were characterized by X-ray diffraction and ...
Searching for suitable catalysts for a passive direct methanol fuel cell cathode
(Elsevier, 2015)
Trimetallic PtMRu/C cathode catalysts with M ¼ Co or Fe obtained by an impregnation procedure using ethylene glycol and NaBH4 as reducing agent, with suitable activity for the oxygen reduction reaction (ORR) and improved ...
Encapsulación de compuestos biocidas en materiales silíceos mesoporosos
(Investigación Joven, 2015)
Se llevó a cabo la síntesis de materiales silíceos mesoporosos con diferentes grados de ordenamiento (SBA-15, MCF). Se estudió su uso como matrices estabilizadoras de un biocida comercial. Mediante adsorción/desorción de ...
Research on methanol tolerant catalysts for the oxygen reduction reaction
(Springer, 2015)
Direct methanol fuel cells (DMFCs) generate electricity in a clean and efficient way, so they are a valuable alternative to traditional environmentally harmful technologies. Portable power sources are one of the applications ...
Estudio de diferentes condiciones de síntesis para la obtención de zeolita NaA a partir de cenizas volantes
(Investigación Joven, 2015)
En este trabajo se propuso zeolitizar una ceniza volante industrial a través de un proceso hidrotermal. Para ello, se probó mejorar su reactividad sometiéndola a un pretratamiento de calcinación en presencia de compuestos ...
Evaluation of pH-sensitive poly(2-hydroxyethyl methacrylate-co-2- (diisopropylamino)ethyl methacrylate) copolymers as drug delivery systems for potential applications in ophthalmic therapies ocular delivery of drugs
(2015)
Smart polymers like pH sensitive systems can improve different pharmacological treatment. In this work the behavior of copolymers containing 2-hydroxyethyl methacrylate (HEMA) with different proportions of 2-(diisopropyl ...
Evaluation of pH-sensitive polyurethane 2-diethylaminoethyl methacrylate hybrids potentially useful for drug delivery developments
(2015)
Smart sensitive polymers have been used to improve processes in drug delivery. In this article, we evaluate the behavior of polyurethane/N,N-diethylaminoethyl methacrylate hybrids (PU/DEA) as pH- responsive polymers ...
Polyurethane Poly(2-(Diethyl Amino)Ethyl Methacrylate) blend for drug delivery applications
(2015)
A pH-sensitive blend of polyurethane (PU) and poly(2-(diethyl amino)ethyl methacrylate (PDEA) with good film-forming capacity was prepared from the corresponding aqueous dispersions. The polymer matrix was first characterized ...
