    CMU Researchers Praised for Publication
    The world of minerals has many surprises. Searching for cheaper and non-toxic materials that provide high performance without compromising the environment is of paramount importance and complex minerals may be key to sustainable novel technologies.

    CMU researchers Andrew Supka, Rabih Al Rahal Al Orabi, and physics faculty member Marco Fornari, working in collaboration with experimental groups in France and Japan, have discovered ways to improve the properties of mineral Colusite to make it more efficient in transforming waste heat into useful electrical energy.

    Research in thermoelectric energy conversion has led to things such as mini-refrigerators, the source of energy that has kept the Voyager spacecraft alive since 1977, and devices that recover thermal energy losses in the automotive sector.

    The editor of the international edition of Angewandte Chemie wrote: "According to the evaluation of referees the results reported in your Communication are “highly important” or even “very important”. Less than 10% of our manuscripts receive such a positive review.” This paper (https://doi.org/10.1002/anie.201908579) follows work published recently in Advanced Energy Materials (https://doi.org/10.1002/aenm.201803249) and the Journal of the American Chemical Society (http://pubs.acs.org/doi/pdf/10.1021/jacs.7b11224). The combined impact factor of those journals exceeds 47.

    Machine Learning Applied to Materials Science
    Rajendra Joshi and an image representing his research A research article by Rajendra Joshi, a Science of Advanced Materials Ph.D. student from Nepal, was recently published in the journal, ACS Applied Materials and Interfaces.

    His research, supported by grants from the Department of Energy, proposes a method, based on machine learning, that “allows us to do a very quick evaluation of the voltage that a material will provide in a battery,” said CMU physics faculty member Juan Peralta. “Previously, testing materials was time consuming and expensive.”

    If a new material is found to provide useful a voltage, scientists and engineers can use that material to create new battery technologies, thus Rajendra Joshi’s work allows for quicker and cheaper development of real world devices such as laptop computers and cellular phones.

    The properties of a valuable hire
    Required CMU undergraduate physics course takes seriously the matter of employment
    Daniel HatcherDaniel Hatcher is graduating from Central Michigan University this spring with a master’s degree in physics and a graduate certificate in data mining. He has a job lined up at General Motors as a business intelligence data analyst. While he is happy for what his future holds, getting a master's degree is not what he had planned when he graduated from college in North Carolina with a bachelor's degree in physics. He wanted a job. "But I didn't know what I was doing: writing a resume, a cover letter, trying to get an interview," he said. "I was just sitting at my kitchen table, opening job applications, filling them out and sending them off." He said he applied for about 50 positions. "I heard back from one, which told me that I wasn't qualified and asked me if I knew someone who was. It was demoralizing." If he had been a physics undergraduate at Central, he might have gotten that job.

    Seeking keys to the universe
    CMU team runs experiment at superconducting cyclotron to help solve nuclear puzzle
    Alfredo Estrade at the cyclotronWhen two neutron stars collided in 2017 in a never-before-seen event, astronomers and astrophysicists were in seventh heaven, so to speak. Nuclear reactions from the exploding stars rained cosmic debris thought to be the source of gold, silver, platinum and uranium ­­­— heavy elements that astrophysicists say have enhanced the chemical composition of the universe. "My wedding band emerged from a neutron star merger," ScienceNews quoted Harvard theoretical astrophysicist Avi Loeb at the time. Understanding the conditions that create chemical elements is the goal of physics instructors such as Central Michigan University assistant professor Alfredo Estrade. But reproducing on Earth how these and other elements are created in the nuclear reaction of a stellar explosion is impossible — unless each step in the chain is studied separately, he said. To do that, a team of CMU faculty and students recently ran its experiment at one of the world's flagship nuclear science research facilities — the National Superconducting Cyclotron Laboratory on the campus of Michigan State University.

    Physics lab takes quantum leap
    New space allows students to help create new materials for super-fast electronics
    Central Michigan University physics faculty member Junjie Yang likens himself to a farmer. But instead of growing food, he is growing materials to power next-generation electronics and industry — and to empower CMU students to be the next leaders in those fields. Specifically, Yang is growing crystals from atoms, using physics and chemistry. His immediate goal is to create crystals that would be used to replace the current silicon wafers in computers and other electronics, making them much faster with greater memory. His dream is to grow new materials that would enable the control of both their electric and magnetic properties and operate at room temperature.

    Driving for a better fuel cell
    Energy Department grants power the work of an international team of CMU researchers
    Yazan MaseadehWhen Yazan Maswadeh, of Jordan, decided to pursue his Ph.D., he didn't search the web for universities, he looked for researchers who were doing work in his field of crystallography. "I was seeking high-level research. There are very few people in the world who are conducting this kind of research." That's how he found Valeri Petkov, a faculty member in Central Michigan University's physics department. "His research areas interested me," Maswadeh said. "So I just sent him an email saying that I am a student from Jordan who has just finished my master's degree in physics and my research interest is in atomic structural analysis. If you have a Ph.D. position, I would be a valuable component to your research." Petkov interviewed Maswadeh online and encouraged him to apply to CMU. "I did not have prior knowledge about CMU, or where it was located. But I thought 'I'll apply to this university.'" Now as a doctoral student in the Science of Advanced Materials program in CMU's College of Science and Engineering, Maswadeh is part of an international team of CMU researchers working to identify the weak points in fuel cells and give feedback to other researchers to improve them. The research is being funded by another $238,000 in a seven-year string of grants from the U.S. Department of Energy.

  • LIGO uncovers the birthplace of gold and other heavy elements in the death spiral of neutron stars
    Recent discoveries fuel CMU research

    Black Hole collision When the history books are written, the past year in physics will be one remembered by violent cosmic events and the birth of a new type of astronomy – one based on gravitational waves.

    It all started in 2016 with the first detection of a collision between black-holes by LIGO, the Laser Interferometer Gravitational-wave Observatory. As a result, the pioneers behind LIGO's development, Rainer Weiss, Kip Thorne, and Barry Barish, where awarded the 2017 Nobel Prize in Physics. LIGO allows us for the first time to feel --actually hear by means of an actual audible chirp-- the ripples caused to the very fabric of space time when compact objects such as massive black holes and neutron stars many times the mass of our sun merge spiraling into each other.

    But that discovery was just the tip of the iceberg. This week a collaboration of LIGO and other observatories announced the discovery of a merger between two neutron stars, a very exotic cosmic event that had long been predicted by astrophysics theories but never observed. In August 17th, just as the USA was preparing for a solar eclipse, a gravitational wave signal was felt by both LIGO and a similar European observatory (VIRGO), at the same time as a burst of gamma-rays was observed by the Fermi gamma-ray telescope. It looked like a neutron star merger event, so it triggered an alert for a number of survey telescopes that frantically started scanning the sky to find a smoking gun. When a new shiny bright object was found a few hours later in a galaxy far far away (NGC 4993), the astronomy community went into overdrive and every respectable telescope was pointed in that direction!

    A neutron star is likely the most dense and hard and stiff object in the universe; the mass of a star like the sun all packed into a sphere the size of Mount Pleasant! Scientists have long suspected that many of such beasts are not alone, but spend their life dancing around another neutron star partner for millions of years until their orbits become so close that they merge in a violent cosmic collision. After the ripples of the collision where detected by LIGO, optical telescopes observed a beautiful display of cosmic fireworks that shone 200 billion times brighter than our sun and quickly faded away in about a week: the fascinating event was baptized a Kilonova.

    The observation of the neutron star merger is a treasure of data to test physics and astrophysics theories, ranging from cosmology to nuclear physics question. One of the most important pieces of information relates to the origin of the chemical elements in our world, and has CMU Professors Alfredo Estrade and George Perdikakis (and the rest of the nuclear astrophysics community) particularly excited. Astrophysicists had long speculated that during a merger the conditions would be just right so the material spewed out by the collision – mostly neutrons – would rearrange itself in an act of stellar alchemy to create most elements beyond Tin in the periodic table. So astronomers where looking for them in the wreckage of the merger… and they found gold! Not just a bit of gold; Many Septillion - a billion quadrillions (or 10^24) - pounds of gold! Many many gold atoms in mint new condition; enough to make ten planets of pure and only gold with the mass of the earth… And not just gold; also the iodine of your Thyroid, the lead that might poison your water pipes, or the uranium in the core of nuclear power plants.

    What we witnessed for the first time was a nucleosynthesis event that creates all those heavy elements that, after being ejected into the interstellar medium, will be recycled into new planets and stars, in a continuous cycle of galactic chemical evolution. This has confirmed that the bizarre theories about how the elements are formed might actually be correct! It will allow nuclear astrophysicists to test many details about theories on the origin of the elements – for example how the nuclear reactions that Prof Estrade and Perdikakis measure with experiments at accelerator labs contribute to the formation of gold and other heavy elements – and likely discover new surprises along the way.

    CMU student gets competitive fellowship
    Physics major devotes years to reaching coveted goal
    Reed Kolany​Reed Kolany, a physics major at Central Michigan University, certainly isn't one to stand around and wait for opportunity. Back when he was a CMU freshman, the Naperville, Illinois, resident decided he wanted to be a medical physicist. Not long after, he set his sights on a highly competitive fellowship offered by the American Association of Physicists in Medicine. He knew that as a freshman he'd likely be turned down. So Kolany decided to "build his resume" like fine masonry and wait to take his biggest swing as an upperclassman. And so, it happened. By the middle of his junior year the fellowship was his. Kolany was one of seven students in the country to land one.

    solar eclipseThe upcoming solar eclipse has some Central Michigan University faculty so pumped that they're hitting the road to catch the event in its full glory. The moon will cover 80 percent of the sun when the eclipse hits Michigan on Aug. 21. That sounds like a lot, but the difference between 80 percent and the full shot is huge, according to Axel Mellinger, an associate professor in CMU's physics department. "Some people have compared it to watching the Super Bowl from the parking lot versus being inside the stadium," he said.​

  • CMU nuclear astrophysics experiences around the world
    Nuclear astrophysics, as an interdisciplinary field, requires a coordinated effort from various areas in physics and astrophysics to answer its most challenging questions. Experimental and theoretical nuclear physics, astrophysical models, astronomical data, or atomic physics experiments, are some of the fields that contribute to our understanding of the stellar processes that enrich the chemical composition of the universe. This expertise is often scattered across distant institutions, and even different countries, and international workshops and conferences are essential to keep the field moving forwards. In recent months three graduate students from Central Michigan University had the opportunity to participate in such meetings. Panagiotis Gastis, and Stylianos Nikas attended the Astrophysical Nuclear Reaction Network School in Schmitten, Germany, to learn about modern computational tools in nuclear astrophysics. Neerajan Nepal participated in the Joint JINA/CEE Winter School on Nuclear Astrophysics in Shanghai, China, which aimed to bring together young researchers in the field from the US and China. Both of them presented talks about their research projects in these meetings. It was an enriching experience, not only through learning of new scientific tools and topics that apply to their own research projects, but also from the opportunity to expand their network of fellow scientists around the world.

  • CMU researchers study isotopes at national superconducting cyclotron
    In February 2015, CMU M.S. physics student Adam Bryce and physics professor Matthew Redshaw participated in an experiment at the National Superconducting Cyclotron Laboratory to measure the atomic mass of two radioactive carbon and oxygen isotopes. The isotopes that were studied have fewer neutrons than the stable carbon and oxygen atoms found in nature, so only live for a few minutes after they are created with the cyclotron accelerator. However, this is enough time to catch them in an ion trap and measure their atomic mass to a precision of a few parts-per-billion. The results have been used to study the so-called superallowed beta-decays that these isotopes undergo and contribute to tests of fundamental theories in physics, including the Standard Model of particle physics. The results were recently published in two papers in the high-impact physics journal Physical Review Letters.
