This review provides an exhaustive overview of unsteady fields that can vary in one, two, or three dimensions of space, as a powerful tool to direct the self-assembly of magnetic colloids into structures with tunable properties. Unlike steady fields, unsteady (nonstationary) fields can overcome the limitations of classical dipolar interactions, leading to a much wider range of structures, ranging from dense crystalline aggregates to 3D spanning networks, or dynamic clusters. The ability to precisely control the amplitude, frequency, and field direction allows for fine-tuning the interplay of interparticle forces, resulting in controllable assembly pathways. This review analyzes how different types of unsteady fields influence the morphology and dynamics of the self-assembled structures.

This article explores the application of linear viscoelastic principles to soft glassy materials by employing the effective time theory that readjusts the material clock to address the time dependence associated with the same. We explore how the effective time domain approach validates key linear viscoelastic principles, including the Boltzmann superposition principle, convolution relation, time–temperature superposition, time–stress superposition, and the Fourier transform relationship between relaxation modulus and complex modulus.

The essential encapsulation strategies require further refinement for long-standing stability. Material engineering, including compositional tuning and defect passivation, has shown promise in enhancing intrinsic perovskite stability.
