In Chapter One, Zahra Sayyar, Navideh Anarjan, Hoda Jafarizadeh Malmiri, and Aydin Berenjian discuss nanoemulsions and their low-energy and high-energy production methods. They also examine modern techniques for the identification of nanoemulsions and review their stability. Next, Chapter Two by Bogdan-Constantin Neagu and Gheorghe Grigoraş proposes the use of artificial intelligence techniques like clustering and fuzzy modelling to determine slow voltage variations among other things. In Chapter Three, Navideh Anarjan, Hamideh Vaghari, Hoda Jafarizadeh-Malmiri, and Aydin Berenjian explore bioreactor models applied to bioprocesses and solid-state fermentation processes in order to produce pertinent biomolecules for industrial applications. Akihiro Otsuka, PhD explores the correlation between fluctuating electricity rates and demand in Chapter Four. In Chapter Five, Samuel Olusegun David and Gulum Mert present a study wherein biodiesel production via waste cooking oil is examined. Oludolapo A Olanrewaju and Caroline C Olanrewaju review studies on energy consumption prediction through the application of neural networks, as well as machine and equipment processes, in Chapter Six. Lastly, Takeo Oku and Tatsuo Oku explore the development of carbon/copper-based materials through the addition of titanium in Chapter Seven.
