Phase-field method (PFM) has become a mainstream computational method for predicting the evolution of nano and mesoscopic microstructures and properties during materials processes. The paper briefly reviews latest progresses in applying PFM to understand
We found that the metallic ground states appeared in the films grown at low temperatures. The electronic ground states were further investigated by the electronic-structure calculations. Results suggest that the electrical properties of Ti2O3 films were governed by the c/a ratio of the crystal ...
We believe that cellulose acts as a buffer alleviating the mechanical stress to which the element is subject during the lithium insertion/de-insertion process. In fact, an electrode made from nanometric Sb prepared in the absence of cellulose was found to perform poorly; thus the capacity ...
The metallic structures in this study are Ru x /Co x , Ru x /Pt x , and Ru x /Al x , each individual layer having a thickness of x = 10 nm. For comparability, each one of the four constituent metals was also produced as single-element sample with 10 nm layer thickness. ...
A modified semi-empirical foam deformation model is proposed to capture the oscillating hardening and softening mechanical behavior of ordered structures in the plateau stress region and is fit to all three lattice structures printed in this study. Finite Element Analysis (FEA) of the deformation ...
Helium is a noble gas that has the lowest boiling point of all elements and is the second lightest element in the universe. It’s also the only element that was discovered outside of Earth before it was found on our planet. Helium is used in a variety of applications, from filling ballo...

Metallic glass has the potential to replace palladium, an expensive element that is currently used in hydrogen systems. The lack of economically feasible energy storage systems is the main hindrance preventing hydrogen energy from scaling up to the industrial level. With the new development, the...
Element sulfur in nature is an insulating solid. While it has been tested that one-dimensional sulfur chain is metallic and conducting, the investigation on two-dimensional sulfur remains elusive. We report that molybdenum disulfide layers are able to serve as the nanotemplate to facilitate the for...
Its modular structure allows solving of different field equations in a fully coupled way with a staggered approach, using Fast Fourier Transform (FFT) and Finite Element (FE) based solvers provided by the PETSc numerical library21,118,171. The pre- and post-processing of DAMASK facilitates ...
