Experimental investigation on recycling carbon dioxide into fuel using solar thermochemical cycle based on cerium oxide

Increasing in energy consumption that relies on fossil fuels has caused a crisis in energy sources availability and an increase in the amount of emissions such as carbon dioxide, emissions threaten life on earth due to global warming and climate change, this promotes many research movements in the areas of clean and renewable energy to reduce emissions and capture it from atmosphere. This research aims to convert carbon dioxide to fuel using solar energy, driven by the chemical reaction. The experiment investigates the possibility of converting CO2 into a flammable substance, 'fuel,' and adds economic value to it. The efficiency of converting solar energy into fuel in this experiment is (1.84%) for the first cycle and (1.06%) for the second cycle

Experimental study on pyrolysis of sugarcane bagasse for bioenergy production

Energy is the economic backbone. Nowadays, the demand for cheap and clean energy has become the primary and most priority of every country looking to develop while maintaining its environment. Energy demand is increasing continuously due to rapid growth in population and industrialization development. The major energy demand is provided from fossil fuel sources. There are increasing environmental problems associated with the current use of fossil fuels. The potential for biomass to supply much larger amounts of useful energy with reduced environmental impacts than fossil fuels is this study's aim. In this study, lab-scale pyrolysis was designed and fabricated to analyze syngas and bio-oil components from two sugar cane bagasse samples, the first sample from Kenana and the second sample from White Nile. The analysis of thermochemical and physical properties showed that the calorific value and density were equal to 41.67 MJ/kg, 1.07925 kg/m3 and 40.671 MJ/kg, 1.1309 kg/m3 for both bio-oil and tar, which proves that bio-oil would be an environmentally friendly alternative that can be used for transportation and different industrial sectors

Genitourinary Pathology (Including Adrenal Gland)

Our aims in constructing the Genitourinary Pathology chapter are to describe neoplasms of the adrenal gland, urothelial tract, kidney, penis, prostate, and testis in a manner that is both useful for the practicing surgical pathologist and that may be used as a reference for all students of urologic pathology. Whereas the text and figures describe the salient morphologic, immunohistochemical, and molecular attributes for each tumor type and encompass the latest classification schemes, the narrative integrates the clinical and pathological findings that are commonly encountered during surgical pathology sign-out of these cases. Accordingly, it is our hope that this chapter will serve as a guide for both general and subspecialized pathologists in contemporary practice
