Scalable Two-Dimensional Materials Advance Future-Gen Electronics
For the first time, physicists have built a two-dimensional experimental system that allows them to study the physical properties of materials that were theorized to exist only in four-dimensional space.
A team of researchers from Penn State placed first at the Materials Research Society (MRS) iMatSci Innovators competition at the MRS 2017 Fall meeting in Boston. Their technology, called “LESS,” reduces the amount of flush volume required to remove solids and residue from toilet bowls by 90 percent and could improve hygiene and save significant water resources in water-scarce environments.
Providing safer drinking water to those in need may be a little easier. According to Penn State researchers, a new desalination technique is able to remove salt from water using less energy than previous methods.
Penn State’s investment in its interdisciplinary research institutes, including the Materials Research Institute (MRI), has created a culture of strong collaborations across disciplines. At Penn State, many researchers have the support of both their academic departments and the university-wide institutes, such as MRI. By encouraging crosscutting research, MRI and its sister institutes open up traditional silos of knowledge to the stimulus of other viewpoints and new ideas. This mingling of disciplines, often called “convergence,” brings together the physical and life sciences with engineering and computation to solve the most complex problems facing society today and in the future.
The foundations of crystal chemistry were developed in the early 1900s when scientists realized that a combination of factors including atomic/ionic radii, electronegativity difference, and preferred valence could be used with incredible success to understand and predict an enormous spectrum of crystalline solids. For 100 years, the materials community depended on this approach to guide material engineering efforts. This presentation introduces the concept of entropic stabilization, an orthogonal approach to materials design, where one uses configurational entropy to stabilize new crystals that “escape” conventional predictive power. We will demonstrate the ability to incorporate metal cations into “unusual” structural environments, and potentially realize new materials with interesting structures and physical properties.
How Stuff Moves in Turbulence: From Particles to Animals
Fluid turbulence is everywhere in the natural and engineered world: a complex tangle of vortices and eddies that span a wide range of length and time scales. However, from the point of view of objects and animals suspended in turbulence, this complexity is highly dependent on scale. Small, nearly-massless things are passive tracers, completely at the mercy of the surrounding flow; large, massive things can pass through even strong turbulence without being affected too much by it. In between, there is a continuum of spatiotemporal complexity where suspended matter is intermittently affected by turbulence. We will explore these intermediate scales and their physics, and discuss what they can teach us about both engineering and biology.
The 2DCC-MIP is focused on advancing the synthesis of 2D materials within the context of a national user facility.
The Materials Characterization Lab (MCL) is a fully-staffed, open access, analytical research facility charged with enabling research and educating the next generation of highly qualified researchers.
Our primary goal is to support internal and external users working in computer-based simulations of materials across the various length and time scales.
