Speaker: Roozbeh Tabrizian, Univ. Florida

February 28 @ 11:00 am - 12:00 pm
EB1 – Room 1011, 911 Partners Way
Raleigh, NC 27695-7907 United States

Speaker: Roozbeh Tabrizian Affiliation: Univ. Florida Abstract: The Smart Connected World paradigm is based upon communication hardware that meet stringent requirements on performance, size, weight, and power consumption (SWaP). For example, the new wireless protocols (i.e. 5G and beyond) enforce extreme enhancement of spectrum use efficiency, bandwidth, and reconfigurability, which requires substantial transformation of available RF front-end modules. In this talk, I will discuss mixed-domain RF nano-systems that are realized at the intersection of semiconductor electronics, nano-acoustics, and atomic-layered ferroelectrics.…

Speaker: Dr. Sajeev Gupta, University of Akron

March 5 @ 11:00 am - 12:00 pm
EB1 – 3003, NC United States

Speaker: Dr. Rajeev Gupta Affiliation: University of Akron Abstract: High strength, lightweight, low cost, and corrosion resistant alloys are needed to meet the current demand for increasing the fuel efficiency of vehicles, decreasing the carbon emission, and increasing the service life of engineering components. However, the development of the alloys with properties beyond conventional limits has been hindered by the limited understanding of the structure/processing/property/performance relationship at various length scales, lack of manufacturing technologies to engineer desired microstructure, and exploration…

Speaker: Kenneth Graham, U of Kentucky

March 6 @ 11:00 am - 12:00 pm
EB1 – Room 1011, 911 Partners Way
Raleigh, NC 27695-7907 United States

Speaker: Kenneth Graham Affiliation: U of Kentucky Abstract: Organic thermoelectrics and perovskite solar cells are both promising technologies for generating electricity in a more sustainable manner. Organic thermoelectrics, which are typically based on doped π-conjugated polymers, provide a means of converting waste heat to electrical energy using low-cost and mechanically flexible devices. On the other hand, perovskite solar cells rely on low-cost and solution processable organic metal halide perovskites to efficiently convert solar energy to electrical energy. For both material…

Speaker: Dr. Siddhartha Pathak, Univ. of Nevada, Reno

March 19 @ 11:00 am - March 20 @ 12:00 pm
EB1 – 3003, NC United States

Speaker: Dr. Siddhartha Pathak Affiliation: Univ. of Nevada, Reno Abstract: Materials with modified surfaces – either as a consequence of a graded microstructure, or due to an intentional alteration of the surface – are of increasing interest for a variety of applications ranging from enhanced wear and corrosion resistance,  superiorthermal and biomedical properties, higher fracture toughness, and reduced stress intensity factors etc. Quantifying the resulting property gradations poses a significant challenge, especially when the changes occur over small (submicrometer) depths,…

Speaker: Connal Murray, IBM

March 20 @ 11:00 am - 12:00 pm
EB1 – Room 1011, 911 Partners Way
Raleigh, NC 27695-7907 United States

Speaker: Dr. Connal Murray Affiliation: IBM Abstract: The emergence of quantum computing has enabled new paradigms of solving problems considered intractable on classical computing platforms. A critical link in its implementation is the understanding of what constraints pose the greatest limitations on qubit performance. Qubit scaling follows different metrics than those associated with classical computing, driven by the requirement that the fragile states they possess can be retained for sufficiently long times. After a brief introduction into superconducting transmon qubits,…
