	abstract = {A plane wave self-consistent field calculation was parallelized over two node cards of an IBM BlueGene/P supercomputer. A maximum speedup of 9x was measured in Virtual Node execution mode. The observed performance improvements are consistent with Amdahl{\textquoteright}s law for an algorithm that is approximately 89\% parallelizable.},

We utilized a 1 x 1 ZnO hexagonal wurtzite unit cell in a 4-atom bilayer configuration, with one Zn atom replaced by a Co atom. We found that the original lattice parameters of ZnO did not change appreciably upon Co alloying, and thus the structure remains robust. Similarly, minimal charge redistribution between the metals and oxygen is observed. Lastly, our calculations showed that the net magnetization of ZnO upon Co alloying is enhance significantly, much larger than that via doping. The results suggest that\&nbsp;<span style="font-size: 13.008px; line-height: 20.0063px;">Zn<span style="font-size: x-small;">0.5</span>(Co)<span style="font-size: x-small;">0.5</span>O</span>\&nbsp;as a ferromagnetic material is a potential candidate for advanced spintronic applications.</div>},

	abstract = {<div>This study aims to determine the dynamics of a spherical particle that is suspended in a fluid that is confined between two parallel moving walls. A simulation was done using the molecular dynamics software LAMMPS. It was observed that the particle tends to move toward the wall nearer to it and that its equilibrium displacement is approximately proportional to its initial distance from the center. It was also observed that increasing the wall velocity increases the magnitude of this lateral displacement.</div>},
