Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Doctoral Thesis / Dissertation from the year 2016 in the subject Chemistry - Analytical Chemistry, grade: 82.5, Gujarat University, course: Chemistry, language: English, abstract: The aim of this research was to synthesize and study batch properties of zeolite synthesized from Bagasse fly ash and its derived zeolitic material. To achieve this, a study was carried out with the following objectives. To synthesize zeolites from Bagasse fly ash solution via microwave assisted hydrothermal synthesis process. To study the effect of adding electrolyte and electrolyte with sodium silicate to BFA solution towards the development of zeolitic material. To investigate the effects of adding sodium hydroxide and sodium hydroxide plus sodium meta silicate for activation of BFA. To examine the structural characteristic of the synthetic zeolite produced (i.e. morphology, physico-chemical and phases identification) via XRF, SEM, FTIR, PXRD, TGA, BET and BJH and to evaluate the sorption capacity of the synthesized zeolitic material using aqueous solution of aromatic compoundsResearchers in science and engineering have increased interest in finding low-cost adsorbents such as industrial sludge waste, biomass, husk, slag, carbon slurry, bagasse fly ash (BFA), etc. to remove inorganic and organic pollutants from wastewater. There are many researcher results which were done on BFA for the removal of pesticide, dye, phenol etc but during survey of literature no research work is done on the removal of aniline, nitrobenzene and para nitroaniline using BFA and its derived zeolitic materials. Zeolites are aluminosilicates crystalline materials which contain pores and cavities of molecular dimensions. Many occur as natural minerals, but it is the synthetic varieties which are among the most widely used sorbents.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book studies the evolution of scalar cosmological perturbations in the 1+3 Covariant Gauge-Invariant formalism for generic f(R) theories of gravity. It provides with a complete set of equations describing the evolution of matter and curvature fluctuations for a multi-fluid cosmological medium. It also deals with a specific model of a radiation-dust fluid universe described by barotropic equations of state where the perturbation equations are applied around a background solution of a specific toy model of gravity and looks at exact solutions for scales much smaller and much larger than the Hubble radius. 100 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -For a hundred years now, Einstein's General Relativity theory has played a pivotal role in our understanding of the Universe. But the recent realization of the accelerated cosmic expansion has put modern cosmology in crisis, mainly because this new realization implies most of the matter and energy content of the Universe exists in a not-yet-understood dark energy form. The existence of dark energy and dark matter (another little understood, non-luminous form of matter) has led to the conclusion that the general relativistic formulation of gravity does not provide a complete description of the Universe on large scales, and has therefore motivated the cosmology community in the search for new underlying physics. One possible modification of General Relativity comes in the form of f(R) theories of gravity. This book explores possible implications to cosmology of this class of modified gravitational physics. 196 pp. Englisch.…
