MEAM/LRSM Seminar: “Enabling Soft, Flexible 2D Materials and Sensors”
Low temperature synthesis of high quality 2D materials directly on flexible substrates remains a fundamental limitation towards realization of robust, strainable electronics possessing the unique physical properties of atomically thin structures. Here, we describe room temperature synthesis of uniform, stoichiometric amorphous MoS2, WSe2, and other transition metal dichalcogenides and subsequent large area (>5 cm2) photonic […]
MEAM Doctoral Dissertation Defense: “Additive Manufacturing and Mechanical Properties of Cellulose Nanofibril Materials”
Cellulose nanofibrils (CNFs) are a nanomaterial derived from plants that have high specific stiffness and strength, can be made into optically transparent materials, and are biodegradable. These properties make CNFs an attractive building block for bulk structural materials. However, CNFs are typically produced in aqueous suspension at low CNF weight fractions (<1 wt.%), which makes […]
MEAM Seminar: “A Multi-Scale Homogenization Model for the Viscoplastic Response of Polar and Sea Ice”
The rheology of polar ice evolves in response to weather and climate changes, by modifying its microstructure. While the experimental evidence for the dependence of rheological properties on the microstructure is well documented, there are only a few modeling efforts to capture the rheological behavior of polar ice, mostly by fitting continuum models to the […]
MEAM Seminar: “Effect of Nanoparticle Size on the Mechanical Properties of Nanoparticle (NP) Assemblies”
Nanoparticle assemblies (NPAs) have attracted tremendous interests of various research communities. The particle-size-effect on mechanical properties of NPAs is systematically studied. With decreasing the particle size d from 300 nm to 10 nm, the SiO2 NPAs become drastically harder (∼39×), stiffer (∼15×), and tougher (>3.5×). The results are consistent with the data scattered in the […]

MEAM Seminar: “Tribofilms at the Asperity Scale”
The presentation will start with an introduction to tribology. This term was first used in a 1965 UK government report which identified the economic loss due to preventable wear and poor friction performance. It helped bring together the diverse community of engineers and scientists that need to collaborate in order to tackle the complex interactions […]
