Organic photovoltaics (OPVs) can potentially provide a cost-efficient means of harnessing solar energy. However, optimum OPV performance depends on understanding the process–structure–property (PSP) correlation in organic semiconductors. In the w

In this paper, we study three dimensional microstructural evolution in a symmetric ternary three-phase eutectic alloy using phase-field simulations under directional solidification conditions. While previous studies have explored the influence of vol

In this paper, we explore the morphological evolution during two-phase growth in the Sn-Zn eutectic system, which has a particularly low volume fraction of the minority Zn phase. The reason for this choice is its exotic nature, as even with such a lo

Eutectic solidification gives rise to a wide range of microstructures. A commonly observed morphology is the periodic arrangement of lamellar plates with well-defined orientations of the solid–solid interface in a given eutectic grain. It is typica

Eutectics are self-organized composite materials that exhibit a wide variety of microstructural features. Besides intrinsic materials properties like interfacial energies or diffusivities as well as the nature of the phase diagrams, the process param

In this paper, we investigate three-phase eutectic growth during thin-film directional solidification of a model symmetric ternary eutectic alloy. In contrast to two-phase eutectics that have only a single possibility, ${\alpha}{\beta}{\alpha}{\beta}

Very thin metallic films are susceptible to dewetting upon thermal excursions, resulting in fragmentation and hence loss of structural integrity. Herein, 15 to 55 nm thick Cu films deposited on a Si substrate were isothermally annealed at 400 to 700
In this paper, we formulate a phase-field model for the computation of equilibrium configurations of multiple phases that arise out of a solid-state precipitate reaction, in the presence of coherency stresses. Here, we utilize the phase-field framewo

The synthesis of benzo[f]chromeno[3,4-b]quinoline-6-ones has been achieved via one-pot three-component reaction from substituted aromatic aldehydes, 3-aminocoumarins, and 2-naphthol in n-butanol using 10 mol % of N-tetrabutylammonium tribromide (TBAT

Eutectic solidification in ternary systems is a complex process involving the interaction of several material and process parameters resulting in the formation of intriguing patterns. Recently, we have observed the evolution of complex patterns in th
