Stimuli-responsive colloidal crystals with reconfigurable structures and properties have garnered significant interest in fields focused on the development of on-demand optics, adaptive catalysts, as well as chemical and biological sensors. A variety of different assembly techniques have been developed to engineer colloidal crystals. However, most reported structures are static as...
There has been significant growth in applying composite materials for various engineering applications in the past several decades. Composites allow engineers to tailor material microstructures and constituents for desired structural properties that usually outperform traditional engineering materials such as alloys. However, due to the heterogeneous nature of composites' microstructure, composite...
Atrial fibrillation (AF) is the most common cardiac arrhythmia, and associated with increased risk for ischemic stroke and mortality. While the risk of stroke has been shown to be reduced with the use of oral anticoagulants like Warfarin, these medications are predictably linked with an increased risk of bleeding, and...
Early-stage oxidation and corrosion mechanisms of CoCrMo and NiCrMo alloys can be analyzed on the nanoscale by transmission electron microscopy. Both alloys are attractive for a broad array of applications such gas turbines and aircraft engine components as they are known for their excellent corrosion resistance and mechanical properties at...
Deformation in materials with a hierarchical microstructure is expected to be complex because of the interaction between the units that form such a microstructure. The complexity of deformation would be even higher when additional inelastic deformation modes are active in such materials, apart from traditional elastic and plastic deformation modes....
Polymer nanocomposites are a class of advanced materials comprised of soft polymer matrix and nano-filler inclusions. While it has been found qualitatively that enhancements of material properties could be achieved by dispersing inorganic nano-particles into organic polymer matrix, the intrinsic governing principles of such composite has not been thoroughly studied...
Recent studies have shown that many high profile studies in biology could not be reproduced, calling into questions the legitimacy of their findings. These reports have the potential to greatly jeopardize the credibility of scientists in the field as well as erode public confidence in the scientific enterprise. Computational research...
Segregation of polydisperse granular materials remains to be a challenging problem in many industrial processes. However, most studies have focused either on bidisperse (two different particle size species) materials, which are not representative of most real mixtures, or on polydisperse materials in an idealized simple geometry. Additionally, most studies have...
Rapid changes in global climate are pushing nations to reduce CO2 emissions and adopt clean energy technologies for renewable energy generation and storage. As wind and solar are implemented worldwide, a commensurate response in energy storage will need to be installed to meet fluctuations in peak energy demands and generation...
