The Challenge
Graphene, a single-atom-thick film of graphite, has shown immense potential in various applications since its discovery in 2004. While its electrical and thermal conductivity made it attractive for electronics, its optoelectronic capabilities were initially overlooked. However, it soon became clear that graphene could serve as a transparent conducting electrode, offering comparable or better performance than indium tin oxide (ITO). Despite its potential, fabricating high-quality, large-area graphene films remains a challenge. This has hindered the practical application of graphene in optoelectronics and photonics, particularly in the field of plasmonics, which deals with the efficient excitation, control, and use of plasmons. The diffraction limit of light poses a fundamental challenge in photonics, but plasmonics helps address this by enabling light confinement at the nanoscale. Researchers at Purdue University, led by Alexander V. Kildishev, are leveraging simulation tools to overcome these challenges and bring graphene closer to practical applications.
About The Customer
The customer in this case study is the Birck Nanotechnology Center at Purdue University, led by Alexander V. Kildishev, an associate professor of electrical and computer engineering. The center is at the forefront of research in combining graphene with plasmonics to develop next-generation optoelectronic devices. The team is focused on leveraging the unique properties of graphene to create tunable photonic devices, particularly in the mid-infrared and near-infrared ranges. Their work involves both simulation and experimental testing to optimize the design and performance of these devices. The center is equipped with advanced computational tools and high-performance computing resources, allowing them to perform complex numerical modeling and simulations. The team is also exploring the potential of graphene in various applications, including night vision, thermal imaging, and biosensing. Their research aims to overcome the current limitations in graphene fabrication and pave the way for its practical use in a wide range of optoelectronic and photonic applications.
The Solution
To address the challenges in graphene fabrication and its application in plasmonics, the team at Purdue University is leveraging advanced simulation tools. They use COMSOL Multiphysics software to perform numerical modeling and optimize the design of graphene-based devices. By simulating graphene as a two-dimensional material, they achieve better agreement with experimental results. The team has demonstrated tunable graphene-assisted damping of plasmon resonances in nanoantenna arrays, which is crucial for designing tunable photonic devices in the mid-infrared range. These devices have applications in sensing and imaging, particularly in the detection of molecular vibrations. Additionally, the team has shown efficient dynamic control of Fano resonances in hybrid graphene-metal plasmonic structures at near-infrared wavelengths. This is important for telecommunications and optical processing. The predictive power of COMSOL Multiphysics models is vital for designing tunable elements for next-generation plasmonic and hybrid nanophotonic on-chip devices, such as sensors and photodetectors. These devices could be used in multicolor night vision, thermal imaging, and biosensing. The team is also exploring the potential of graphene in the quantum optics regime, which could lead to significant advancements in the science of light and the development of smaller, more efficient devices.

Hospital Inventory Management
The hospital supply chain team is responsible for ensuring that the right medical supplies are readily available to clinicians when and where needed, and to do so in the most efficient manner possible. However, many of the systems and processes in use at the cancer center for supply chain management were not best suited to support these goals. Barcoding technology, a commonly used method for inventory management of medical supplies, is labor intensive, time consuming, does not provide real-time visibility into inventory levels and can be prone to error. Consequently, the lack of accurate and real-time visibility into inventory levels across multiple supply rooms in multiple hospital facilities creates additional inefficiency in the system causing over-ordering, hoarding, and wasted supplies. Other sources of waste and cost were also identified as candidates for improvement. Existing systems and processes did not provide adequate security for high-cost inventory within the hospital, which was another driver of cost. A lack of visibility into expiration dates for supplies resulted in supplies being wasted due to past expiry dates. Storage of supplies was also a key consideration given the location of the cancer center’s facilities in a dense urban setting, where space is always at a premium. In order to address the challenges outlined above, the hospital sought a solution that would provide real-time inventory information with high levels of accuracy, reduce the level of manual effort required and enable data driven decision making to ensure that the right supplies were readily available to clinicians in the right location at the right time.
