Modeling materials with phase field crystal models [PDF]
, 2010 The phase field crystal (PFC) model is a novel approach for modeling phenomena on atomistic length and diffusive time scales. In this dissertation, we present new advances in the methodology of the PFC model and describe applications to solidification ...

Phase Field Modeling of Dendritic Growth on Spherical Surfaces
Frontiers in Materials, 2020 The spontaneous formation of a crystal phase is one of the most common and beautiful pattern formation mechanisms in nature. Different instabilities in the crystal interface may lead to the growth of ramified structures, known as dendritic crystal growth.

Revisiting phase diagrams of two-mode phase-field crystal models [PDF]
Computational Materials Science, 2016 In this work, phase diagrams of a modified two-mode phase-field crystal (PFC) that show two-dimensional (2D) and three-dimensional (3D) crystallographic structures were determined by utilizing a free energy minimization method. In this study the modified two-mode PFC model (presented by E. Asadi and M. Asle Zaeem, Comput. Mater. Sci. 2015) was used, in

Molecular Oncology, EarlyView.Combining osimertinib with the STING agonist ADU‐S100 activates innate and adaptive immunity to overcome the non‐inflamed microenvironment of Egfr‐mutant lung cancer. This combination increases NK and CD8+ T‐cell infiltration, associated with activation of the STING‐IRF3 pathway and local immunogenic cell death.

Electric-Driven Polarization Meta-Optics for Tunable Edge-Enhanced Images
Micromachines, 2022 In this study, we demonstrate an electrically driven, polarization-controlled metadevice to achieve tunable edge-enhanced images. The metadevice was elaborately designed by integrating single-layer metalens with a liquid-crystal plate to control the ...

Magnetic phase transitions in Gd64Sc36 studied using non-contact ultrasonics [PDF]
, 2013 The speed and attenuation of ultrasound propagation can be used to determine material properties and identify phase transitions. Standard ultrasonic contact techniques are not always convenient due to the necessity of using couplant; however, recently ...

Molecular Oncology, EarlyView.We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Eighth-order phase-field-crystal model for two-dimensional crystallization [PDF]
Physical Review E, 2010 We present a derivation of the recently proposed eighth order phase field crystal model [Jaatinen et al., Phys. Rev. E 80, 031602 (2009)] for the crystallization of a solid from an undercooled melt. The model is used to study the planar growth of a two dimensional hexagonal crystal, and the results are compared against similar results from dynamical ...
