To achieve net zero emissions has become an important goal over the coming decades. There are two prominent approaches to reaching this formidable and critical goal: finding all available clean energy technologies and utilizing CCUS (Carbon capture, utilization, and storage) to reduce the inevitable emissions. The primary scientific objective of the energy and environmental field is to understand better the influence of molecular-scale processes on macroscopic realistic cycles and mass transfer in the natural environment. It is essential to utilize a multidisciplinary/interdisciplinary approach to reveal molecular-level problems posed by complex energy and environmental systems, providing the information about chemical speciation, spatial distribution, and physical association needed to understand the processes leading to their formation or alteration. One main target is to establish a method to reveal unique information on the identity of minor phases and the speciation of ions in a solution medium. Mechanistic reactions for aqueous-mediated nucleation pathways with transient intermediates occurring in nanoscale dimensions are also needed to unravel these complexities.
