In situ control is a research area that focuses on controlling and manipulating materials or processes directly within their natural environment. This approach allows researchers to study and make real-time adjustments to systems without disrupting them or removing them from their original setting. In situ control is particularly important in fields such as materials science, chemistry, and biology, where understanding the behavior of materials or biological processes in their natural environment is crucial. This research area is advancing rapidly with the development of new technologies and techniques for real-time monitoring and control.
