Conferences and Presentations:

Prof. Kausik Sarkar (MAE) and his Ph.D. students, Amit Katiyar and Shirshendu Paul, attended the 164th Annual Meeting of the Acoustical Society of America, held October 22-25, in Kansas City. Amit presented a talk titled "Effects of damping on frequency dependent subharmonic threshold for contrast microbubbles," which showed that because of the enhanced damping of contrast microbubbles, the subharmonic threshold minimum for ultrasound contrast agents occurs at a frequency different from what was classically predicted in the bubble dynamics literature. Shirshendu's talk, "Echogenicity and release characteristics of folate-conjugated ELIPs for cytosolic delivery of cancer drugs," showed specialized sound-reflecting liposomes delivering cancer drug doxorubicin inside a breast cancer cell and showed that the delivery can be enhanced by ultrasound pulses.

At a separate event, Prof. Sarkar gave an invited talk on the research being pursued in his lab on ultrasound contrast agents and liposomes. He delivered the talk, titled "Encapsulated Microbubbles: From echocardiohgraphy to noninvasive blood pressure monitoring and targeted drug delivery," on October 26 at Drexel University's Department of Chemical and Biological Engineering.

Other News:

Prof. Michael Plesniak (MAE) was a member of the Technical Review Committee of the US Food & Drug Administration (FDA) Center for Devices and Radiological Health, Office of Science and Engineering Laboratories, Division of Solid and Fluid Mechanics in October 2012. The review was conducted as part of the Science Prioritization Process FY 2012-2014, which "seeks input from stakeholders in the Center, Agency, and experts outside the Agency so that the Office can begin to explore appropriate directions so as to undertake relevant and still value-added research."

Student News:

ECE doctoral student Marjan Nabili gave an oral presentation titled "Ultrasound-enhanced Delivery of Antibiotics and Anti-inflammatory Drugs into the Eye" at the Biomedical Engineering Society 2012 Annual Meeting, held October 24-17, in Atlanta, GA. Marjan’s advisor is Prof. Vesna Zderic.

Other News:

The GW Institute for Nanotechnology (GWIN) is pleased to announce the call for proposals from University faculty interested in nanotechnology research. This competition is primarily for junior faculty to help them establish an active research program. Funds may be requested for faculty summer support, equipment, supplies, and salary for postdoctoral researchers and research assistants. Funds must be used by June 30, 2013. Award can be up to $10,000. GWIN expects to fund one proposal. Proposals are due to Prof. Michael Keidar, GWIN director, by 5:00 pm, Thursday, November 8, 2012. Electronic submissions are required.

Guest Vignette:

This fall, GW’s Engineers without Borders chapter (EWB) teamed up with the D.C. professional chapter of EWB to volunteer for the 2012 Broadcom MASTERS competition. Broadcom MASTERS is a national STEM competition created by the Society for Science and the Public for middle school students around the country. From thousands of contestants who participated in science fairs around the United States, 30 finalists were selected to travel to Baltimore, MD, to showcase their projects and compete in STEM-related activities for a grand prize of $25,000.

A group of 16 GW students from EWB worked with the EWB’s D.C. professional chapter to design and facilitate an engineering challenge that relates to the water purification work EWB does in El Salvador. The group created a competition in which the middle school students worked in teams to determine the relationship between height and water pressure in order to find the elevations needed to successfully distribute filtered water from a communal tank to each house in a small village. The weekend in Baltimore allowed EWB members to encourage the top middle school students from around the country to stay involved in science and engineering and to use their knowledge and successes to help benefit others both locally and globally. If you are interested in learning more about Engineers without Borders at GW, please contact us at Professor Riffat serves as the faculty advisor for EWB.
