Emily Lakdawalla: “Speak Your Science- How to Give a Better Presentation”

Posted on by

In September, Emily Lakdwalla from The Planetary Society visited OSU and gave a talk on giving better presentations, scientific or otherwise. If you were unable to attend the colloquium her full presentation is now available on YouTube. For more information about Emily and her work, please visit The Planetary Society website.

Abstract: Bad presentation often gets in the way of great science. Professional meetings are an opportunity for scientists to communicate with potential collaborators, employers, or funders about their exciting work. Unfortunately, many people squander their opportunities in the spotlight by delivering confusing, boring, or just plain bad presentations. I’ll provide guidelines on how to prepare a conference talk that will educate and perhaps even entertain, whether your audience is one of skeptical peers or the general public. Much of the advice also applies to writing about your science.

CEM Researchers’ Theory First to Explain Phenomenon

Researchers Offer Explanation for Strange Magnetic Behavior at Semiconductor Interfaces

Discovery Could One Day Lead to Electronic Materials that Provide Both Computation and Data Storage

Prof. RanderiaCOLUMBUS, Ohio—They’re not exactly the peanut butter and jelly of semiconductors, but when you put them together, something magical happens.

Alone, neither lanthanum aluminate nor strontium titanate exhibit any particularly notable properties. But when they are layered together, they become not only conductive, but also magnetic.

In the current online edition of Nature Physics, researchers at The Ohio State University report the first-ever theoretical explanation to be offered for this phenomenon since it was discovered in 2004.

Understanding how these two semiconductors interact at their interface could someday lead to a different kind of material—one that provides a single platform for computation and data storage, said Mohit Randeria, co-author of the paper and professor of physics at Ohio State.

“The whole question is, how can you take two materials which do not conduct electricity and do not have magnetic properties, make a sandwich out of them and—lo and behold—at the interface tween them, charge begins to flow and interesting magnetic effects happen?” he said.

Brillson receives Interdisciplinary Research Award

Posted on by

CEM Faculty member Len Brillson was awarded, in conjunction with Profs. Wu Lu and Stephen C. Lee, a Lumley Interdisciplinary Research Award. The three professors, members of the Departments of Electrical & Computer Engineering (Brillson, Lu) and Biomedical Engineering (Lee), have worked together to research the use of Field-effect Transistors (FETs) as protein sensors for biomedical applications. The development of this technology may lead to faster and cheaper diagnostics in clinical, biotechnological, and environmental applications.

The Lumley Interdisciplinary Research award was established in honor of John H. Lumley, a 1927 graduate of ceramic engineering, in 2002 to recognize interdisciplinary research accomplishments of College of Engineering faculty and research staff.

Congratulations Len!

Article on Ferrimagnetic Epitaxial Films published in APL

Posted on by

A team of CEM researchers including Profs. Fengyuan Yang, Pat Woodward, David McComb, Hamish Fraser, & Patricia Morris, as well as student and staff researchers Jeremy Lucy, Adam Hauser, Hailong Wang, Jenni Soliz, Manisha Dixit, and R. Williams have published an article in Applied Physics Letters titled, “Buffer-layer enhanced structural and electronic quality in ferrimagnetic Sr2CrReO6 epitaxial films.”

The article describes how the structural and electronic qualities in Sr2CrReO6 epitaxial films were enhanced through the minimization of defect states, particularly at the substrate – film interface. Minimization of the defect states was achieved through epitaxial growth of the Sr2CrReO6 double perovskite on an insulating and non-magnetic double perovskite buffer layer, Sr2CrNbO6. Crystalline quality and Cr/Re ordering in this material are crucial for intrinsic behavior such as semiconductivity at room temperature.

CEM team’s research in IEEE Spectrum article

Posted on by

The work of one of CEM’s teams of researchers has caught the attention of the writers at IEEE Spectrum. The team led by Profs. Josh Goldberger, Roland Kawakami, and Jay Gupta is working on creating 2-D structures of germanium and studying the new material’s capabilities for transporting electrons. In July 2013, IEEE Spectrum published an article reviewing the latest research on 2D materials titled, “The Flat Menagerie”, in which the 2-D research team’s work is mentioned. An abstract can be viewed here.
