Surface force-mediated adhesion, i.e. via van der Waals forces, is critical for the direct bonding of bulk solids in the absence of an adhesive layer. However, no two surfaces are perfectly flat nor conformal and some have intentional patterns, which leads to imperfect adhesion, i.e. interface adhesion strength that is below its ideal strength. In […]
Molecular dynamics simulations allow for the visualization and analysis of atoms and molecules. The choice of boundary conditions in these simulations can impact the overall system, and is an important design decision. In particular, open boundary molecular dynamics simulations is one type of methodology that allows for the treatment of atomistic models with non equilibrium […]

Non-equilibrium phenomena are ubiquitous across material systems and of great technological relevance. Examples of such phenomena include diffusion processes in liquid and gases, viscoelasticity and plasticity in solids, and rheological behavior of colloidal and granular media. Despite their ubiquity and importance, the understanding of non-equilibrium phenomena remains in its infancy compared with classical equilibrium thermodynamics […]

With the advent of more capable and cheaper legged robots, robotic legged locomotion is becoming an increasingly attractive solution for locomotion and embodiment. Legs offer expanded capability over wheeled robots, albeit at the cost of complexity and efficiency. For example, walking robots explore rubble-filled caves, inspect industrial sites, move around human spaces (e.g., stairs), and […]

Unlike diseases with strong genetic predisposition, such as cancer, there exist no accurate personalized diagnostic tools for disorders such as Hypertensive Pregnancy Disorders (HPD) and its mechanism remain understudied. For the purpose of performing diagnostics, we require disease indicators (biomarkers) that are strongly correlated with the underlying condition, i.e. absolute vascular pressure for hypertension. Measuring […]
"Visualizing Genetics: Quantifying Gene Expression Through Genetic and Epigenetic Modifications" Abstract: Precise control over gene expression is essential for proper development of an organism. However, genes are regulated in a variety of ways, the mechanisms of which are not well understood. This thesis explores gene regulation at two different levels: genetic control and epigenetic control. […]

Materials with electroprogrammable stiffness and adhesion can enhance the performance of robotic systems but achieving large changes in stiffness and adhesive forces in real time is an ongoing challenge. Electroadhesive clutches can rapidly adhere high stiffness elements, although their low force capacities, high activation voltages, and inability to separate and turn off stiffness changes reliably […]

Lithium metal battery systems (LMBs) are being sought as an ultimate replacement to LIBs, potentially increasing the cell energy by over fifty percent due to the high capacity and low voltage of the metal anode. Analogous improvement in energy is possible with sodium metal batteries (NMBs) and with potassium metal batteries (KMBs), where existing ion […]
