Research Corporation for Science Advancement Award goes to Dr. Adriana Banu!

Dr. Adriana Banu is one of the 2014 recipients of the Single-Investigator Cottrell College Science Award from the Research Corporation for Science Advancement to support her nuclear astrophysics research project entitled "Determination of Key Astrophysical Photonuclear Reaction Cross Section Towards Understanding the Origin of p-Nuclei". Several undergraduates from the Physics and Astronomy Department at JMU are heavily involved in the project!!!

Below is the abstract of the project:


The proposed research aims to contribute to enhancing the current state of fundamental knowledge on a forefront topic in nuclear astrophysics - the nucleosynthesis beyond iron of the rarest stable isotopes (the origin of the p-nuclei). More specifically, it is focused on constraining the origin of the p-nuclei through nuclear physics by investigating, as a first step, the cross section measurement of the ⁹⁴Mo(g,n)⁹³Mo reaction, a key photonuclear reaction for understanding the astrophysical p-process (the mechanism responsible for the origin of the p-nuclei). The experimentally unknown reaction cross section is proposed to be studied close to and above the neutron threshold with quasi-monochromatic photon beams at Duke University's High Intensity Gamma-ray Source (HIgS) facility, which is currently the most intense accelerator-driven g-ray source in the world. Total cross section measurements of the ⁹⁴Mo(g,n)⁹³Mo reaction with an energy threshold at 9.7 MeV will be performed at beam energies starting from above the neutron thresholds up to around 13 MeV in steps of 100 - 150 keV. A highly enriched target sample of the ⁹⁴Mo isotope is required. Neutrons from the (g,n) reaction will be detected using an assembly of 4pi ³He proportional counters developed at Los Alamos National Laboratories and presently available at HIgS-Triangle University Nuclear Laboratory (TUNL). 

CCTV Discussion Panel on the challenges for electric cars with Dr. Haraldsen

On Sunday February 16th 2014, Dr. Haraldsen (@JMU Physics) appeared on CCTV's World Insight to discuss the challenges that electric cars have to face. The major issues are cost, range, environmental savings. In the segment, it is discussed that, while the cost for some electric vehicles are becomes more reasonable for the average consumer, the range for the cheaper electric cars does not even come close to challenging conventional gasoline powered cars. Therefore, it is critical for research and development of more advanced battery technologies.

As for environmental savings, electric cars are highly dependent on the methods being used to produce electricity. Given that China, India, and the US are still very dependent on fossil fuels (coal, natural gas, and petroleum), the assertion that electric cars are zero emission is a fallacy. By charging your electric vehicle using coal and natural gas you are still producing massive amounts of carbon dioxide (CO2).

For example, the Tesla Model S ($70k - $100k) has the ability to travel around 255 miles on a single charge due to its large 85 kWh battery (initial charge). If you charge the Model S with electricity from coal (2.08 lbs. CO2/kWh), then you produce ~176 lbs. of CO2 and particulates. If you look at an average gasoline power vehicle with 30 mpg, then you use about 8.5 gallons of gasoline in a 255 mile trip. Given that gasoline, on average, produces 22 lbs. CO2/gallon, this gasoline powered vehicle will have released ~187 lbs of CO2 and particulates, which is about the same as the electric vehicle. If you have a Toyota Prius (~50 mpg), then that drops to 112 lbs. CO2 released. Furthermore, charging with natural gas (1.22 lbs. CO2/kWh) will help reduce the CO2 to 103 lbs., which puts it a slight bit better than the Prius. Therefore, if a country like China or the United States is serious about reducing carbon emissions, then there needs to be a planned move toward alternative, non-carbon producing power sources.

The main advantage of an electric car is that they are dependent on the source of electricity, and as the electric grid move toward more efficient and clearer energy sources, electric cars will become clearer as well.

Below are pictures from the discussion panel on CCTV News. Here is the video link for the discussion on electric cars.

Collaboration paper accepted to Journal of Physical Chemistry Letters!

Our first collaboration paper between Dr. Costel Constantin's group and Dr. Patrick Hopkins' group (from UVa) has been accepted into the Journal of Physical Chemistry Letters (see reference below). In this paper, we measured the thermal conductivity of solid, water insoluble thin films of bovine serum albumin and myoglobin proteins.  The measurements preformed in the temperature range 77 - 296 K indicate an anharmonic coupling of vibrations that is contributing to thermal conductivity.  Our own undergraduate, Chester Szwejkowski, is also a co-author on this work and he will join (as a graduate student!) Patrick's lab this Fall of 2014.  We wish him GOOD LUCK!

COE Award for Improving Undergraduate Physics Education

As a following up on the previous post on this national recognition of our department, we now have the official statement of why we were chosen.  From the American Physical Society:

James Madison University sustains a thriving physics department that has grown significantly over the past 15 years. The Department of Physics & Astronomy has developed a culture of engaging students in the education process through an emphasis on undergraduate research experiences, personalized attention and advising, hiring for mission, recruiting and outreach efforts, and an ongoing move to research-based pedagogies and assessment.  Especially notable are the range of program offerings to serve a broad student population, including tracks in applied physics and technical communication, in addition to strong teacher education efforts as a PhysTEC site.

Department Recognized

We received notice yesterday that Physics and Astronomy at JMU has been selected to receive the Improving Undergraduate Physics Education Award from the American Physical Society's Committee on Education.

The award will be announced at the APS April Meeting in Savannah, GA.  Along with the honor and a plaque, we will have recognition on the APS website, the AAPT eNNOUNCER and the APS Forum on Education Newsletter.

We are all very excited by this recognition. Previous recipients of this award are Colorado School of Mines, Kettering University, Massachusetts Institute of Technology, University of Wisconsin at LaCrosse, the Compass Project at UC Berkeley, Mount Holyoke College, University of Illinois at Urbana-Champaign, and Utah State University. This puts us in good company and we are proud to be among their number.

If you were looking for just one more reason to consider JMU as the place to come study physics, isn't this it?

Infrared power generation in an insulated compartment

Thermoelectric power generators can help harvesting infrared radiation from the sun and transform it into electricity.  These devices can produce a voltage difference linearly proportional to the temperature difference between the two junctions.  This phenomenon is known as the Seebeck effect.  JMU researchers lead by Dr. Scarel have found that, when infrared radiation activates a thermoelectric power generators, the Seebeck effect is violated.  The first results will soon be published in a paper accepted by Complexity:  Y. Schwab, H. S. Mann, B. N. Lang, J. L. Lancaster, R. J. Parise, A. J. Vincent-Johnson, and G. Scarel, “Infrared power generation in an insulated compartment”.  Complexity, in press (2013).  Undergraduate students played a key role in the research: Yosyp Schwab set up the data acquisition system and performed the data analysis, Harkirat Mann compared the data with those produced by the Seebeck effect, and finally Brian Lang explored diligently the literature to find similar and related experiments.  More is to come!

JMU undergraduates attending Conference Experience for Undergraduates (CEU13) in Newport News, VA

Bryan Isherwood (left) and Daniel Votaw (right) at the CEU13 poster presentation session

Every year in conjunction with the Fall meeting of the Division of Nuclear Physics of the American Physical Society takes place also the Conference Experience for Undergraduates (CEU). The goal of this event is to provide a "capstone" conference experience for undergraduates students who have conducted research in nuclear physics, by providing them the opportunity to present their research to the larger professional community and to one another. Additionally, it enables the students to converse with faculty and senior scientists from graduate institutions about graduate school opportunity.

This year the meeting took place 23-26 October 2013 in Newport News, VA, and JMU was represented by two of our physic majors, Bryan Isherwood (senior) and Daniel Votaw (junior), who do research in nuclear astrophysics under Dr. Adriana Banu's supervision. Moreover, both Bryan and Daniel have been awarded funding by the CEU13 review committee to attend the meeting for their high quality research accomplishments, which is remarkable taking into account the high number of applications (over 170) and a finite budget.

At what rate is work done by this machine?

In this video, there is an electric motor running at 200 rpm. It is connected to a series of gears each of which reduces the rotation rate by a factor of 50. After 12 such reductions, the last gear is turning at a rate of 1 rev/2.3 trillion years. Just for emphasis, this last gear is set in a block of concrete. 

So as an interesting exercise, at what rate is this machine doing work?

The Quest to Produce more Physics Teachers

Dr. Brian Utter  and colleagues have obtained a Physics Teacher Education Coalition (PhysTEC) grant to support, ultimately, the production of more well-qualified high school science teachers.  But this grant does more for our department and JMU students than encourage the production of much-needed teachers. It is giving our upperclassmen an opportunity to really learn physics by helping to teach it. It has spurred the reform of our introductory physics classes, making them more engaging and productive. It has brought a Teacher-in-Residence to the department to help connect our department to the College of Education, the prospective high school teachers, and give the TIR some experience outside the usual high school classroom.

The recent article in the Breeze give more details.

Physics Major Writes a Book

It isn't often that a freshman write a book that is published. It is even less often that this freshman is a physics major. Evan Meekins fits into this narrowly defined category.  He has written a young-adult fantasy novel called The Black Banner that will hit the stores nationwide next month. You can find more details on the Breeze.

More proof that physicists can do anything!

Time-lapse photography

This amazing time-lapse video is the result of the photographer, Shane Black, traveling over 13,000 miles and capturing over 10,000 photos. The results is remarkable. 

Producing More Physics Teachers

Dr. Utter and several of his colleagues in Physics, Psychology, and Education have been awarded aa $300,000 grant from the Physics Teacher Education Coalition. This grant is intended to make it possible for JMU to produce more qualified Physics teachers.  Along the way it is doing much more than simply generating more people interested in teaching physics. It is changing the way we teach physics in our department.

Check out the full article for all the details.

An example of a Heat Engine

A start-up company has designed and built a device to convert heat into electricity. By heating one end in a flame or over a burner and cooling the other end with a reservoir of water, a temperature difference is created by which electricity can be produced. Thermodynamics in action!

Amazing astronomy photos

The folks over at PetaPixel  held an astronomy photography contest and have now posted the winners. Above is the overall winner. The picture is described as

First up is the overall winner and winner of the Earth and Space category taken by Australian photographer Mark Gee and seen at the top. It’s called “Guiding Light to the Stars,” and it shows the Milky Way seemingly emerging from the light of a New Zealand lighthouse.

Truly larger than life

A. Einstein statue on the Washington mall.

One of the figures that looms larger than life in our nation's capitol is Albert Einstein. While we can't all be Einsteins, we can all make contributions to science and science education (in and out of the classroom). This photo was taken by Dean David Brakke.

Ever wonder what physicists do?

David Saltzberg, right, hosts his "Geek Of The Week," UCLA student Andrew Peck.

Professor David Saltzberg, UCLA has one of the cooler jobs in physics. He is the consultant for the award winning television show Big Bang Theory to make sure that all the science is correct. There is a great article about him and his role in the program on NPR today.

If you don't already have enough reasons to consider starting a career in physics JMU, maybe this helps.

JMU Plays Role in the APS/AAPT Physics Department Chairs Meeting

On May 30 and 31 this year, Steve Whisnant represented JMU as a a member of the steering committee for the annual Department Chairs Meeting. This meeting hosted jointly by the American Physical Society and the American Association of Physics Teachers give department chairs from across the nation to gather and share ideas.

The APS web site has all the details and several quotes from Steve about ideas we pursue at JMU for recruiting (that seem to be working!).

Anca Constantin's Search

There is also a story on the JMU banner page now about our own Dr. Anca Constantin and her research. This makes two stories that currently showcased that highlight the work of our faculty and students.

When Dreams Become Real

There is a great article about one of our outstanding students, Devin Buennemeyer. I urge everyone to go read it. 

Incoming class of Physics majors

We are on track for another banner year. In Phys 105, we have a total of 43 enrolled! Three of these are already JMU students who are changing majors but the remainder are new students to the program. This is a significant increase from last year's record class of 34.  Shanil Virani is doing an excellent job with the recruiting and here we see the evidence.

May Commencement 2013

This spring saw a another fine group of students heading out into the world. Our graduating class this year was 14, a bit off our peak, but numbers in the pipeline suggest that this is about to turn around. We are proud of all of our students, large class or small.

We wish them all well and ask that they all keep in touch. And when they are rich and famous...donate!

SuperMoon on June 23?! Don't Believe the Hype!

At several of our FREE public Saturday afternoon shows this month at the John C. Wells Planetarium at JMU, we have been asked about claims made online regarding the "SUPERMOON" on June 23. Maybe you've seen this image online:

Some places have even gone so far to suggest that this "super moon" will cause natural phenomena such as severe weather or earthquakes!! My response? Don't believe the hype -- this is just bad science!!

Let's dig deeper. You may have seen images on Facebook or elsewhere stating that June's full moon will be the "largest and closest". While true you really couldn't tell the difference between June's full moon and any other month's full moon -- the effect is small! It certainly will not be as large as seen in the posters used to advertise the event! To demonstrate, here's an animated gif that a fellow planetarium colleague has created showing all the full moons in 2013.

Can you tell the difference? NOPE! So all this nonsense is just that! Don't believe the hype!!

NOTE: In a past blog post regarding a "Super Moon", while remaining skeptical of the whole notion, I stated that "... if this event gets people outside to enjoy our night sky that is slowly disappearing because of light pollution, then I think that's 'mission accomplished' ". I still support that idea, and in fact, I think every full moon is a beautiful site! Indeed it still amazes me today that we have sent 12 astronauts to walk on that body [and if you think it is wrong that we don't recognize that tremendous accomplishment, please sign my online petition!]. But since this meme keeps coming back again and again, it important that we debunk the bad science! 

So if you see this idea circulating amongst your social network, set them straight!

Infrared and thermoelectric power generation

On May 23 2013, the undergraduate students Yosyp Schwab, Harkirat Mann and Brian Lang presented new findings on radiative polaritons and thermoelectric and infrared power generation at the 91^th Annual Meeting of the Virginia Academy of Science,Virginia Polytechnic Institute and State University; Blacksburg (VA).  Here are the details of the two oral presentations:

Yosyp Schwab, H. S. Mann, and G. Scarel, “The signature of radiative polaritons: dielectric function and simulated spectra”

and

Harkirat S. Mann, Y. Schwab, B. N. Lang, A.E. Masters, and G. Scarel, “Fluctuations in thermoelectric and infrared power generation”.

On the other hand, under an extremely high humidity (!!! see photo) on May 15 Dr. Scarel presented some of the latest results of the Group at the Fudan University, Department of Microelectronics; Shanghai (China).  The title of the talk was: “Atomic layer deposited oxide films for infrared and nighttime solar cells”.

We hope to get more results during the summer!

 

Nanodays Event 2013!

Usually when the weather is nice people do not like to visit museums, but our Nanodays event had over 80 people visiting the Explore More Discovery Museum in Harrisonburg, VA.  This event gave the possibility to young K-12 kids to learn cool stuff about Nanotechnology!  I hope now they know why water cannot penetrate certain textiles, or why some metals like to have a "memory" of their own!

Spring Picnic 2013

On April 7 we once again descended on Purcell Park for the annual spring picnic. In addition to the usual soccer game there was a bit of slack-lining and shelter climbing. Oh yeah, there was good food provided by the cook, Costel Constantin. More pictures are found here.

The end of the semester is approaching fast (or slow, depending on your point of view). This is typically the last gathering of the majors before graduation. At least they can now study on a full belly.

Department Video

Just before spring break this year, a video crew visited out department and spent the day interviewing and videoing us as we teach, engage students in research, and talk about our outreach programs. This video is part of a collection of videos make at physics departments across the country to be showcased on the APS TV YouTube channel. These videos are being promoted vigorously at the APS March Meeting in Baltimore, March 18-22, 2013.

As you can see from the APS YouTube site, we are one of 17 domestic and 1 international Physics Department being highlighted. There are few undergraduate only departments included, so we are especially proud of being an example of a such a department.

Enjoy the video and come for a visit some time to see it in person.

Symposium 2013

On March 16th, we held our annual Spring Symposium in which our students present their work from the previous year. This year there were 15 excellent presentations on a wide variety of topics spanning the universe from sub-atomic to galactic scales.

Our special guest this year, Dr. Dennis McNabb from Lawrence Livermore National Laboratory, gave a departmental colloquium on Friday afternoon and a public lecture Saturday evening in Wilson Hall. His public presentation was entitled: "Harnessing Fusion Power on Earth".


This year the symposium was held in the John C. Wells Planetarium and more photos are found here.

JMU Physics Awarded PhysTEC Grant to Support Physics Teacher Education

JMU is about to become one of the newest PhysTEC-supported sites in a nationwide effort to improve and promote the training of physics teachers. As high school physics enrollments continue to climb, only around a third of high school physics teachers have a major in physics or physics education. In fact, a 2010 American Association for Employment in Education report ranked physics as the subject with the highest demand for teachers out of 60 subjects considered. 

As the shortage continues, there is a pressing need for inspired teachers with a solid foundation of physics content and insight into the challenges and opportunities unique to physics pedagogy.

With a $300k grant from PhysTEC (Physics Teacher Education Coalition), JMU will become the newest comprehensive site to address this need. The award was announced in 2012 to fund efforts implemented starting in Fall 2013 and is coordinated by a project team that includes collaboration among faculty in Physics & Astronomy (Brian Utter, Scott Paulson, Mark Mattson), Psychology (David Daniel), the College of Education (David Slykhuis), and Harrisonburg High School (Andy Jackson). The overarching goal is to offer a program in which students can explore teaching as an option, gain teaching experience, learn about physics pedagogy, and engage with a community of fellow students. A few of the main PhysTEC elements that will be implemented in Fall 2013 include:

• Physics Pedagogy Course: A two-credit 200-level physics teaching methods course developed by JMU Psychology Professor David Daniel, an expert in the science of learning and STEM education, in collaboration with local physics teachers, will be offered each fall. The class focuses on Pedagogical Content Knowledge -- that is, the study of effective teaching strategies specifically in the context of physics education. Topics such as metacognition, scaffolding, technology, conceptual change, and pre-conceptions are discussed in terms of the challenges in teaching and learning physics.

• Teacher in Residence: Each year, an experienced high school physics teacher will work for a year in residence in the Department of Physics and Astronomy as a local expert in high school physics teaching. As a front-lines expert, the TIR will serve as a voice of experience in the pedagogy course, a mentor for students interested in pursuing teaching, a liaison with the College of Education, and a motivator and organizer for the JMU physics teaching community.

• Learning Assistant Program: Beginning in 2011, introductory physics courses included a new way to grapple with the sometimes challenging concepts that students encounter in learning physics. Undergraduate Learning Assistants (LAs) were hired to facilitate weekly tutorials that focus on conceptual stumbling blocks that many students encounter. “Tutorials in Physics,” based on the work of the Physics Education Research group at the University of Washington, focuses on common hurdles in learning physics. In weekly prep meetings, LAs anticipate the likely problems and discuss strategies for facilitating the discussions. While primarily intended to improve the learning of students in introductory physics, the LA program offers the ideal way for sophomore physics majors to get teaching experience (and get paid!).

These are just a few of the many plans that are part of our PhysTEC program. We’re excited about these and other opportunities for our students that will be enabled by our collaboration with PhysTEC and we’re looking forward to a great start in the fall!

For additional information on JMU PhysTEC or the Secondary Education Track in Physics, please contact Dr. Brian Utter (utterbc@jmu.edu). 

New Grant Awarded to Costel Constantin

Yesterday, in a small ceremony with President Jon Alger and Provost Jerry Benson, the second round of 4VA mini-grants were awarded. Last fall, Costel was among the first group to be awarded one of these. This time, he was the first at JMU to receive what is called a Step-up Grant. The mini-grants are $5,000 and intended to seed a new collaborative initiative with colleagues at other Virginia institutions. The Step-up grant is a good bit larger - $20,000.

More details are found here.

Congratulations to Costel on this big step forward in his research.

Radiative polaritons at JMU

Radiative polaritons are known since their theoretical description by Fuchs and Kliewer in the sixties.  However, the reason why they are radiative was not explained, the existence of the radiation emitted was not proved, and the frequency range of that radiation was never found.  Three undergraduate students at JMU with the help of collaborators at the University of Utah and Howard University have done all this: Anita discovered why radiative polaritons are radiative, and Yosyp discovered the existence of the emitted radiation.  Yosyp and Harkirat found that the "radiated" radiation exists in the microwave to far-infrared frequency range.  For more details see the paper:  A.J. Vincent-Johnson, Y. Schwab, H.S. Mann, M. Francoeur, J.S. Hammonds, and G. Scarel, “Origin of the low frequency radiation emitted by radiative polaritons excited by infrared radiation in planar La₂O₃ films”.  J. Phys: Condens. Matter 25, 035901 (2013).

Virginia Academy of Science - Undergraduate Research Meeting

On Saturday October 27 2012, the Virginia Academy of Science Fall Undergraduate Research Meeting took place at the Reynolds Community College in Richmond.  The JMU Undergraduate student in Physics Harkirat Mann presented a poster entitled "The origin of fluctuations in the heat and radiation excited Seebeeck effect".  Harkirat and his advisor, Dr. Govanna Scarel, describe an apparatus that will help understanding whether an environment free of humidity and heat variations aids in observing delicate voltage transients.  Harkirat will build the apparatus in the next months, and the results of the research will help him and his group to improve the research on harvesting infrared radiation by transforming it into electricity.

Intruguing non-linear phenomena discovered at JMU!

How is it possible that a voltage signal excited by infrared radiation decays as the excitation source remains on?  Anita Vincent-Johnson, who graduated in physics at JMU on May 2012, found that the strange phenomenon might be due to chaotic transport in a thermoelectric power generator interacting with infrared radiation.  The mystery is not fully unveiled and the team of Dr. Scarel continues the investigations.  The latest news were published today:

A.J. Vincent-Johnson, A.E. Masters, X. Hu, and G. Scarel, “Excitation of radiative polaritons by polarized broadband infrared radiation in thin oxide films deposited by atomic layer deposition”.  J. Vac. Sci. Technol. A vol. 31, 01A111 1-4 (2013).

Why Study Physics?

Why should you study physics? Maybe you want to have a job when you graduate -and- make a lot of money? Perhaps you want to go Medical School? How about Law School? Or maybe Business School? Did you know that acceptance into these very competitive programs is (largely) based on your performance on standardized tests like the MCAT, LSAT, & GMAT? Did you know that Physics majors have the highest scores on these tests? That they have the lowest unemployment rates when they graduate? That they have amongst the highest paying jobs with an undergraduate degree in Physics? Besides, PHYSICS IS FUN! Learn more by watching this short clip, and then learn more about the Physics and Astronomy program at James Madison University

Come learn more about Physics & Astronomy at our OPEN HOUSE this Saturday from 9am to noon! Meet students & faculty, tour our labs, watch really cool physics demos, and learn more about the department, our scholarships, and the process at 10am and 11am in Room 2212 in the Physics & Chemistry building!
