Abstract: Cancer diagnoses, and increasingly treatment options, are increasingly being aided by the development of new molecular imaging technologies. Central to the utility of these procedures has been the concurrent development of contrast agents that enable clinicians to clearly delineate tumor peripheries, determine pathologies, and develop personalized intervention strategies. One of the critical challenges faced in cancer bioengineering is the translation of compounds, including NPs, from the current small animal models, and cellular screening tools, to patients.

The study of ion conducting ceramics ushers in a new era of "chemically functional materials." This chemical functionality arises out of the defect equilibria of these materials, and results in the ability to transport chemical species and actively participate in chemical reactions at their surface. Moreover, this chemical functionality provides a promise for the future whereby the harnessing of our natural hydrocarbon energy resources can shift…

Aluminum nitride (AlN) thin films have come to dominate a significant subset of the piezoelectric microelectromechanical systems (piezoMEMS) device world despite exhibiting what can only be described as modest electromechanical properties. In recent years, the AlN-ScN system has received significant interest for its widely-reported increases in field-induced strain. Inspired by the massive property enhancements achievable near phase boundaries in oxide piezoelectrics and armed with high-throughput computational as well as experimental capabilities, we have embarked on a study to develop new…

EB1 – Room 1011, 911 Partners Way
Raleigh, NC 27695-7907 United States

Abstract: Molecular crystals have applications in nonlinear optics, organic electronics, and particularly in pharmaceuticals, as most drugs are marketed in the form of crystals of the pharmaceutically active ingredient. Molecular crystals are bound by dispersion (van der Waals) interactions, whose weak nature generates potential energy landscapes with many local minima that may be extremely close in energy. This often results in polymorphism, the crystallization of the same molecule in several different structures. Crystal structure may profoundly influence the physical and…

Abstract: This talk addresses how grain boundaries (GBs) migrate under a range of different driving forces. Our approach is based on a description of the motion of crystallographic line defects in GB,; i.e., disconnections. First, I will review the relationship between disconnections and the underlying bicrystallography; this relationship determines the set of all allowed Burgers vector and step heights (geometric properties of disconnections) for each GB {b,h}. Next, I will show how GBs move under no driving force and for…

Understanding Grain Boundaries through Crystallography Geometry and Statistics PROF. SRIKANTH PATALA Department of Materials Science and Engineering North Carolina State University Raleigh, NC 27695-7907 Friday, October 4 - 11:00am – EB1 1011 ABSTRACT: Grain boundaries are planar defects that are ubiquitous in engineering materials. In polycrystalline systems, a wide range of phenomena including diffusion, conductivity, failure resistance (corrosion, intergranular cracking, creep, embrittlement, radiation resistance) and thermal stability, depend on the properties of the internal interfaces. While the engineering of grain…

Speaker: Jodie Lutkenhaus Affiliation: Texas A&M Abstract: Sociopolitical pressure towards elemental cobalt drives the demand for new energy storage materials. Specifically, Li-ion battery cathodes contain lithium cobalt oxide (LCO) or lithium nickel manganese cobalt oxides (LNCM), for which some cobalt is obtained from politically sensitive geographical regions or by means of child labor. One solution towards this challenge is the translation of organic or metal-free electrodes to replace of cobalt-containing cathodes. Here, macromolecular radicals as redox-active electrodes for batteries are presented.…

Abstract: Finding more efficient gas−liquid scrubbing systems having lower parasitic energy penalties is important for the future deployment of carbon capture plants for large point source CO2 emitters. Minimization of the energy penalty using advanced solvents is one way to reduce the energy penalty. Non-aqueous, hydrophobic solvents are one type of solvent in which the physical properties of the solvent combined with low heats of absorption and low loading at high temperature, even with high CO2 pressure, result in promising…
