Synthesis and Characterization of Nano Y Zeolite Using MWCNT as Media for Crystal Growth
...Show More Authors

   The present research was conducted to synthesis Y-Zeolite by sol-gel technique using MWCNT (multiwalled carbon nanotubes) as crystallization medium to get a narrow range of particle size distribution with small average size compared with ordinary methods. The phase pattern, chemical structure, particle size, and surface area were detected by XRD, FTIR, BET and AFM, respectively. Results shown that the average size of Zeolite with and without using MWCNT were (92.39) nm and (55.17) nm respectively .Particle size range reduced from (150-55) nm to (130-30) nm. The surface area enhanced to be (558) m2/g with slightly large pore volume (0.231) km3/g was obtained. Meanwhile, degree of crystallization decreased to 120%.

El amor y la mujer en novela "La Voragine"
...Show More Authors

La vorágine es una novela insigne de la literatura colombiana e hispanoamericana que trata de manera singular el tema de la violencia. Este artículo propone una reflexión filosófica novedosa para abordar la violencia como objeto de conocimiento. Se plantea, en primer lugar, un nuevo enfoque a partir de la teoría literaria,enseguida se consideran aspectos del relato, tales como: la doble naturaleza del mundo, el absurdo y la dinámica autoproductiva de la violencia y con ayuda de varios autores, constatamos cómo estos mismos aspectos admiten nuevas aproximaciones. Este artículo nos lleva a pensar nuevas formas de ser y de actuar en el mundo a partir del modo como nos relacionamos con lo otro.

PABLO NERUDA "Premio Nobel" Y SUS ETAPAS LITERARIAS 1904_1973

Si Alfonso x el sabio y la Escuela de Traductores de Toledo habia hecho del castellana una lengua apta para la expresión cientifica, fue Pablo Neruda quien aplicó su sentido artistico para crear una poesia amorosa de caracter lileraria. Por lo tanto, pocos poetas han llegado ton populares come. Pablo Neruda, en el mismg tiempo: se comsidera esccitor de una abundante producción literaria ne sólo en su ciudad natal de (Chile), Sino ha sida uno de los padres de la poesia hispanoamericana contemporónea. Ademas la influencia que ejerció en el grupo de poetas de la Generación del 27, con los que empezó a relacionarse durante su estancia en Madrid, fue decisiva también para la poesia espańola. Esa era la razon principal que me hizo pe

La estructura y el Simbolismo en «Bodas de sangre»
...Show More Authors

Bodas de sangre es una tragedia en verso del escritor Federico García Lorca escrita en 1932, y estrenada el 8 de marzo de 1933 en el teatro Beatriz de Madrid con gran éxito tanto en España como en Hispanoamérica. Fue llevada al cine por Carlos Saura en 1981. Es una producción poética y teatral que se centra en el análisis de un sentimiento trágico. Desde la vida y la muerte, a lo antiguo y lo moderno, en la manera de ver la tragedia. Todo ello enmarcado en un paisaje andaluz trágico y universal.

   El tema principal que se trata en este drama es la vida y la muerte. Pero de un modo arcano y ancestral, en la que figuran mitos, leyendas y paisajes que introducen al lector en un mundo de

Antibiotics adsorption from contaminated water by composites of ZSM-5 zeolite nanocrystals coated carbon
...Show More Authors

The presence of antibiotic residues such as ciprofloxacin (CIPR) in an aqueous environment is dangerous when their concentrations exceed the allowable. Therefore, eliminating these residues from the wastewater becomes an essential issue to prevent their harm. In this work, the potential of efficient adsorption of ciprofloxacin antibiotics was studied using eco-friendly ZSM-5 nanocrystals‑carbon composite (NZC). An inexpensive effective natural binder made of the sucrose-citric acid mixture was used for preparing NZC. The characterization methods revealed the successful preparation of NZC with a favorable surface area of 103.739 m2/g, and unique morphology and functional groups. Investigating the ability of NZC for adsorbing CIPR antibioti

Characterization of (CIGS)/(CdS) Hetrojunction for Solar Cell
...Show More Authors

The CIGS/CdS p-n junction thin films were fabricated and deposited at room temperature with rate of deposition 5, and 6 nm secG1 , on ITO glass substrates with 1mm thickness by thermal evaporation technique at high vacuum pressure 2×10G5 mbar, with area of 1 cm2 and Aluminum electrode as back contact. The thickness of absorber layer (CIGS) was 1 µm while the thickness of the window layer CdS film was 300 nm. The X-ray Diffraction results have shown that all thin films were polycrystalline with orientation of 112 and 211 for CIGS thin films and 111 for CdS films. The direct energy gaps for CIGS and CdS thin films were 1.85 and 2.4 eV, respectively. Atomic Force Microscopy measurement proves that both films CIGS and CdS films have nanostru

The reaction of methyldopa with o-vanillin in refluxing ethanol afforded Schiff base and characterized through physical analysis with a number of spectra also the study of biological activity. The geometry of the Schiff base was identified through using (C.H.N) analysis, Mass, 1H-NMR, FT-IR, UV-Vis spectroscopy. Metal complexes of Cr3+, Mn2+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+ and Hg2+ with Schiff base have been prepared in the molar ratio 2:1 (Metal:L), (L = Schiff base ligand) except Hg2+ at molar ratio 1:1 (Hg:L). The prepared complexes were characterized by using Mass, FT-IR and UV-Vis spectral studies, on other than magnetic properties and flame atomic absorption, conductivity measurements. According to the results a dinuclear octahedral geo
