The phenomenon of rapid industrialization and the subsequent rise in energy consumption have led to the exploitation of natural resources, specifically fossil fuels, for the purpose of power generation. The observed phenomenon leads to introduction a substantial quantity of carbon dioxide (CO2) as a greenhouse gas into the surrounding environment. The effects of CO2 emissions are one of today’s most pressing problems for society. In this context, there has been a lot of interest in the most recent advancement made in a comprehensive CO2 capture strategy. There are many different methods for separating and capturing CO2, including liquid absorption, adsorption on solid surfaces, chemical looping, gas phase separation, and hybrid processes like adsorption-membrane systems. Due to CO2 relatively stable dynamic state, interacting with other substances is complex. Therefore, it is necessary to create specific catalysts that can dissolve the CO2 bond and be used as a feedstock to create highly economical materials. Recently, there has been a lot of interest in using metal oxide-based processes to convert CO2 into other compounds. Metal oxides are essential to CO2 hydrogenation because they offer extra benefits like selectivity and energy efficiency. This book chapter focuses on iron oxide based materials and their utilization in the context of CO2 capture applications. Here, a curated literature review on iron oxide-based materials for CO2 capture application has been presented, and the various strategies used by scientists and industry to reestablish the equilibrium of CO2 in the environment have been analyzed.

The scientific community worldwide has been interested in nanoscience over the past few decades due to its potential applications in the energy, pharmaceutical, agricultural, electronics, medical diagnostics, and chemical industries, as well as in space exploration. These distinctive features of iron oxide nanoparticles (IONPs) can be explored for various additional applications, including medication delivery, biosensing, reusable catalysts, antibacterial and anticancer properties, MRI agents, and medical imaging. Therefore, it is essential to fabricate IONPs with the appropriate monodispersity, structure, size, and topology for the applications. The biofabrication of IONPs with the appropriate nature and structure utilizing microbial machinery is safer, faster, and more ecologically friendly than previous approaches. Many microorganisms have previously been investigated for their ability to fabricate IONPs. As a result, manufacturing IONPs using microorganisms is a novel approach that shows great promise. This chapter offers detailed information on several methods for producing IONPs utilizing microbial cells, as well as their multifunctional applications.

CRADLE-5 is the first pragmatic stepped-wedge trial of a Vital Signs Alert device in a low-income country, evaluating its effectiveness and scale-up across eight districts in Sierra Leone, where maternal mortality rates remain one of the highest globally. The study involved over 93,000 deliveries, trained 2,100+ health workers, and assessed outcome variations across districts and facilities.
Combustion of fossil fuels is one of the main sources of emissions of greenhouse gases such as CO2, CO, and NOx. In order to decrease the emissions of these harmful gases and alleviate their unfavorable consequences, it is crucial to shift toward clean and renewable energy technologies. Aside from the environmental importance, there are other reasons, such as fluctuations in the price of fossil fuels, restrictions in their resources, and the importance of energy diversification for shifting toward alternative and clean energy systems. In this chapter, some of the most conventional and developed renewable energy systems are introduced. Afterwards, the importance of shifting toward renewable energy sources and the development of clean energy technologies is discussed. Following that, the obstacles and challenges related to the development of renewable energy systems are provided. According to the provided data and designed plans by international organizations, it can be concluded that renewable energy systems would have a significant contribution in the future; however, there are some challenges, such as requirement for investment, lack of proper infrastructure, and absence of clear and effective policies in some countries and regions that can act as obstacles to the development of these clean systems.
