Microalgae could play an important role in the achievement of sustainability goals related to the generation of renewable energy and greenhouse gas (GHG) emissions. These photosynthetic microorganisms are able to capture CO2 and, therefore, can be used to produce biofuels such as ethanol, methane and green diesel. Other factors, such as their high growth rate, ability to use wastewater as a culture medium and the ability to grow on non-arable land makes them a potentially economical source of biofuel production on a large scale. This monograph introduces the reader to the basic and applied science of microalgal biofuel production. Chapters in the volume give information about bioethanol and biogas production from microalgal sources, the fermentation process, optimization of culture parameters and industrial applications of biomass projects. The book is a useful reference for biotechnology and environmental science graduates and professionals interested in biofuel production.

Solar Chimney Power Plants: Numerical Investigations and Experimental Validation summarizes the effect of the geometrical parameters of a solar chimney on the airflow behavior inside a solar chimney power plant. Chapters in this experimental handbook are presented in two parts with the goal of equipping readers with the information necessary to study and determine key factors which affect the performance of the solar chimney power plant. In the first part, the authors present a simulation developed by using computational fluid dynamics (CFD) modeling software ANSYS Fluent to model the airflow. The adopted CFD models include k-ɛ turbulence model, the DO radiation model and the convection heat flux transfer model. These models have been validated with anterior experimental results. In the second part, the simulated models are then tested with alternate geometric configurations of the solar chimney power plant. The numerical studies allow readers to consider ways to expand on the design optimizing of the solar chimney when constructing a prototype. Geometrical parameters include the height, the diameter of the chimney and the dimensions of the solar collector and their effect on the temperature and air pressure is documented to validate models used for experimental simulations. The handbook also includes a study of an experimental prototype, constructed at ENIS. The researchers have gathered data on the environmental temperature, distribution of the temperature, air velocity and the power output generated by the turbine, the solar radiation and the gap of temperature in the collector of the prototype.

Rapid Solidification Processing of molten metals and alloys has proved to be a reliable route for producing new and advanced materials. The Chill-Block Melt Spin (CBMS) technique is important because its simplicity, flexibility and perfection. High quality materials can be produced with lower costs, as compared to other routes, by refining the microstructure and trapping the nucleated (new) metastable phases. Melt-spun ribbons subsequently produced can then be consolidated to produce billets and sheets that can be used in many industries especially high-tech industries such as aerospace and racing automobiles. This book contains several perspectives about CBMS technology and should be a useful review for undergraduate and post-graduate metallurgy students.
