Now, they are investigating evidence of more damage when a group of cells breaks off from a colony and more follow, leading to large-scale metastasis.</p><p>Amit Pathak, a mechanical engineer at Washington University in St. Louis who specializes in mechanobiology, plans to take a closer look at various aspects of cell group behavior with a prestigious five-year, $1.9 million grant for early-stage investigators from the National Institutes of Health (NIH). The Outstanding Investigator Award provides support for research that falls within the mission of the National Institute of General Medical Sciences Maximizing Investigators' Research Award (MIRA) program. The funding gives an investigator flexibility to conduct research without specific aims.</p><p>Pathak, an assistant professor in mechanical engineering & materials science in the School of Engineering & Applied Science, plans to build on previous research into cell behavior in mechanically heterogeneous environments. His work centers around the epithelial-mesenchymal transition (EMT), or cells' transition from a group to independence. Epithelial cells, which are found in blood vessels and in the lining of various organs in the body, can change into mesenchymal cells, which are important in both embryonic development and cancer metastasis. Most healthy cells like to stay together, but in disease processes such as cancer, the integrity of the group is somehow compromised. In previous research, Pathak showed that the stiffer the tissues, the more likely EMT will take place.</p><blockquote>"We are very interested in tumor invasion and fibrosis," Pathak said. "In this project, we will look at how group cells behave in confinement, how they process the temporal information as to which environment they are coming from. We're looking at the mechanisms behind disease pathways and fundamental cell behavior to determine how that leads to disease outcome."<br/></blockquote><p>Pathak plans to study the role of confinement on group cells' behavior, measure how deeply cells feel and determine where memory is stored within the cell.</p><p>In the past five years, Pathak and his lab have created a computational model showing that epithelial cells are more likely to break off from their groups when in a confined environment. In addition, they studied the mechanical memories of grouped cells in both soft and stiff environments to show that cells maintain the properties they had in their previous environment before they move. His lab created a patent-pending device that allows them to measure how long the cells' memory lasts in the new environment. Most recently, his lab also found that a defect in tissue boundaries can lead normal cells to take on characteristics of diseased cells, such as cancer cells, and invade the surrounding tissue.</p><p>Pathak's lab conducts both computational modeling and experimentation, which expedites the discovery process. He is participating in the National Science Foundation-funded Science and Technology Center for Engineering Mechanobiology (CEMB), a collaboration between Washington University and the University of Pennsylvania.</p><SPAN ID="__publishingReusableFragment"></SPAN><p><br/></p><br/><br/><div class="cstm-section"><h3 style="margin-top: 0px; font-family: "open sans", sans-serif; font-size: 1.34em; text-align: center; border-bottom: 1px solid #b0b0b0; padding-bottom: 12px;">Amit Pathak</h3><div style="color: #343434;"><div style="text-align: center;"><img src="/Profiles/PublishingImages/Pathak_Amit.jpg?RenditionID=3" alt="" style="margin: 5px;"/></div><ul style="padding-left: 20px;"><li>Assistant Professor of Mechanical Engineering & Materials Science <br/></li><li>Expertise: Biomechanics, biomaterials, mechanobiology of the cell, and interactions between cells and extracellular matrices.<br/></li></ul><p style="text-align: center;"><a href="/Profiles/Pages/Amit-Pathak.aspx" style="background-color: #ffffff;">View Bio</a> <br/></p></div><div> </div></div>Amit Pathak LabBeth Miller2018-08-01T05:00:00ZResearchers are investigating evidence of more damage when a group of cells breaks off from a colony and more follow, leading to large-scale metastasis.<p>​<span style="color: #222222; font-size: 16px;">Pathak to study collective cell mechanobiology in complex matrices </span><br/></p>
https://engineering.wustl.edu/news/Pages/WashU-materials-scientists-combine-supercomputers-to-create-new-strong-metallic-alloys.aspx897WashU materials scientists combine supercomputers, 3-D printers to create strong metallic alloys<img alt="tiny dots of individual candidate alloys" src="/news/PublishingImages/Flores%20research%202018.JPG?RenditionID=1" style="BORDER:0px solid;" /><div id="__publishingReusableFragmentIdSection"><a href="/ReusableContent/36_.000">a</a></div><p>Engineers looking to create high-performance metallic alloys that are resistant to corrosion, fatigue and wear while remaining strong often use a trial-and-error method to find the right combination of elements. Now, engineers at Washington University in St. Louis plan to use computational methods and additive manufacturing to find the best combinations, saving significant time and money.<br/></p><p>Katharine Flores, professor of mechanical engineering & materials science in the School of Engineering & Applied Science, will build on some foundational work in high-entropy alloys — single-phase substances of five or more metallic elements in relatively equal parts — to find new alloys for structural, load-bearing applications, such as in aircraft, power generators and energy storage devices. Instead of the time-consuming trial-and-error method, Flores will work with Rohan Mishra, assistant professor of mechanical engineering & materials science, who will use quantum-mechanical computation to identify combinations of elements that have the most promise. Once identified, Flores will synthesize the alloys using a laser-aided metal-on-<g class="gr_ gr_45 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" id="45" data-gr-id="45">mtal</g> deposition technique to create a library of potential alloys for further testing.<br/></p><p>With a three-year, $496,077 grant from the National Science Foundation, Flores and Mishra will use these methods to look for high-entropy alloys that can withstand high temperatures. Mishra will perform the computational calculations on some of the most powerful supercomputers to identify promising candidates from a large composition space. Then Flores will use her lab's technique to create a 2-D library, a one-inch square piece of metal on which about 100 tiny dots of individual candidate alloys can be fabricated. Flores' laser-deposition technique creates the library in about 30 minutes with just a few grams of material.<br/></p><p>The additive manufacturing technique is similar to polymer 3-D printing where the machine draws the material onto a surface layer by layer. However, Flores uses a laser to melt a small region of a base material, then adds up to four different powders to the melt.<br/></p><blockquote>"What we're doing with this research is changing the composition of the powders as we raster the laser across the surface, and there are a few ways we can do that," Flores said.</blockquote><p>"We can change the composition of the powder continuously to produce a gradient, or we can make individual dots with different compositions."<br/></p><p>While Flores has been doing similar work in bulk metallic glasses for several years, the high-entropy alloys are a new class of materials generating significant interest, she said. One particular attribute that is appealing is that the materials don't undergo phase separation, or become less homogenous at different temperatures as other metals do.</p><p> "On the calculation side, Rohan is going to identify combinations of elements that produce a single phase or produce an interesting combination of other phases," said Flores, who also is director of the university's Institute of Materials Science & Engineering. "He will tell us what combinations to try, then we will deposit those elements and do the microstructural characterization and mechanical property measurements to test the strength and stiffness and map out those properties."<br/></p><p>Once Flores' lab has the measurements, she will provide them to Mishra, who can feed them back into his computational model to improve his predictions. In addition, Mishra's team will use one of the world's most powerful microscopes at Oak Ridge National Laboratory to look at the structure of the materials at the atomic scale.<br/></p><p>In addition to accelerating the development of new alloys, the work will contribute to the growing field of additive manufacturing, which could be used to make complicated parts in a single manufacturing process.<br/></p><p>"When making a part for an airplane that has 20 different pieces that need to go together, if you can make it in one piece, you eliminate all of the fasteners, which means less weight, improved fuel efficiency and reduced manufacturing and maintenance time," she said.<br/></p><p>Previously, Flores' lab created 21 alloys with aluminum, cobalt, chromium, iron <g class="gr_ gr_49 gr-alert gr_gramm gr_inline_cards gr_run_anim Punctuation only-ins replaceWithoutSep" id="49" data-gr-id="49">and</g> nickel and tested them using X-ray diffraction, microscopy and nanoindentation, a method used to test the hardness and stiffness of materials. In research recently published in <em>Intermetallics</em>, the team found that the laser-deposition technique created alloys consistent with those created with traditional methods, showing that the technique is a highly efficient method that can speed up the process of identifying and refining the most promising compositions prior to creating larger quantities.<br/></p><SPAN ID="__publishingReusableFragment"></SPAN><p>Li M, <g class="gr_ gr_44 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" id="44" data-gr-id="44">Gazquez</g> J, Borisevich A, Mishra R, Flores K.
