Modeling at multi-scales, to better understand strongly correlated materials in massively parallel ways
Materials are fundamental to all forms of technology; the examples are all around us.
Exploring EM wave behavior in metamaterials
Various materials can be used to control the path of light or any other type of electromagnetic (EM) wave. For example, the lenses in a pair of eyeglasses are shaped to achieve a desired optical function.
Evaluating organic materials for solar energy
Organic photovoltaic systems (OPVs) have generated considerable interest from researchers in recent years as materials relevant to harnessing renewable and sustainable sources of solar energy. OPVs are called "organic" because the substances are carbon-based, like the molecules of living things.
Investigating new opportunities for doping
Modern flashlights with bright, white LEDs probably use a mixed indium-gallium nitride alloy as semiconductor to convert electricity into light. A Blu-ray disk system also employs a blue InGaN-based laser. However, indium is becoming scarce and costly, sending researchers scurrying to find an alternative technology.
Devising production methods for graphene
Ohio State University researchers recently discovered potential keys to mass producing a specific pattern of graphite in a layer just one atom thick, signaling a breakthrough that could lead to “graphene” challenging silicon as the preferred material for manufacturing faster, more efficient computer chips.
Controlling nanometer-scale structures
Surprising behaviors often arise when small numbers of atoms and molecules are brought into close proximity. Such small aggregates offer a window into an intermediate state of matter between isolated atoms and bulk materials.
Calculating surfaces for graphene growth
The understanding of surface reconstructions has become essential as scientists seek to develop materials with tailored properties. For instance, researchers over the past few years have been searching for a process to mass-produce circuits using a material called graphene – a one-atom-thick layer of graphite – which displays unique electronic properties.
Creating organic magnets from elusive compounds
Fundamental research in chemistry has laid the foundations for the discovery and design of new materials with fascinating magnetic, electrical and optical properties, prompting inventions anywhere from faster computers to lighter long-range planes.
Lacks increasing fundamental understanding of disordered systems
Over time, the properties of polymer materials slowly change through a process known as aging. Aging can cause changes in volume, which may lead to cracks in a material, and alter mechanical properties, making it more brittle. Thus, aging can seriously impact the performance of polymer products used in a wide range of applications.
Jana investigating the potential of carbon nanotubes for industry
Carbon nanotubes (CNTs) attract great attention for their strong potential in applications involving aerospace/naval materials, nano-electrical products, optical devices, chemical sensors, catalyst supports, water/gas treatments, drug carriers and artificial tissues.
