Mark Foster leads team developing a smart in-situ sensor to monitor 3D laser printing in real time

Mark Foster, HEMI fellow and associate professor in the Department of Electrical and Computer Engineering, has received funding via the Cohen Translational Engineering Fund to continue development of a sensor that will monitor 3D laser printing in real time with a goal of saving manufacturers time and money.

Foster is lead PI for the project, “SmartAM: A Smart In-Situ Sensor for Metal Additive Manufacturing Qualification and Defect Detection”. His team, consisting of Milad Alemohammad, a postdoctoral fellow, and Steven Storck, a senior materials scientist at the Johns Hopkins University Applied Physics Laboratory, has already created novel, high-speed spectroscopic sensors that can be integrated into laser powder bed fusion printing machines and provide real-time data so operators can correct defective layers as the object is being made.

The sensor was developed at the request of collaborators at JHU APL’s additive manufacturing center. The group also has received $250,000 in seed funding sponsored by the Army Research Laboratory and enabled by the MEDE+ AI-M program at the Hopkins Extreme Materials Institute and has taken part in the National Science Foundation’s I-Corps program through Johns Hopkins Technology Ventures.

Foster plans to use the award from the Cohen Translational Engineering Fund to continue to refine its sensors as well as develop a user dashboard.

Susanna Thon, Paulette Clancy, and Rama Venkatasubramanian join researchers from Morgan State University to establish innovative materials research center

HEMI Fellows Susanna Thon, associate professor in the Department of Electrical and Computer Engineering, Paulette Clancy, professor and head of the Department of Chemical and Biomolecular Engineering, and Rama Venkatasubramanian, team leader in Energy and Thermal Management at the Johns Hopkins University Applied Physics Laboratory, have collaborated with researchers at Morgan State University in an initiative designed to not only advance materials research but also to establish the first center of its kind at any Historically Black College or University.

Ramesh C. Budhani, professor of physics at Morgan State, has recently been awarded a $7.5 million grant from the U.S. Department of Defense (DoD) to found the Center for Advanced Electro-Photonics with 2D Materials. Thon and Clancy serve as co-PIs on the grant. Other key contributors to the project include Venkatasubramanian and David Shrekenhamer from the JHU Applied Physics Laboratory.

“Johns Hopkins is pleased to be a partner with Morgan State on this initiative. By furthering the relationship between our institutions via the Center for Advanced Electro-Photonics with 2D Materials, we are creating pathways of success for students while increasing our research capacity in the area of next-generation materials for a variety of applications,” said Thon. “We are especially excited about the potential to attract top-notch talent to Baltimore by combining the strengths of our two schools.”

Fundamental to the Center’s research operations will be its mission to train underrepresented diverse students by expanding talent pipelines within the technology workforce and defense sector. The exposure of students to specific technologies, and their accumulated experience attained at the newly created center, will increase proficiencies and marketability within private and public sector industries. The cornerstone of the applied experience made available through the Center’s research will be summer internships for both Morgan and JHU students, co-advising of PhD dissertations, and joint annual workshops. Additional funding from the grant will underwrite internships for 10 to 15 undergraduate students and five students from area high schools and community colleges.

“Through the establishment of this center, STEM students have a space to perform cutting-edge research on an emergent class of quantum materials and technologies for clean energy, electromagnetic sensing and information processing,” says Clancy. “They also have the opportunity to create lasting relationships with researchers outside of their home institution. The impact this center will have on the workforce within the materials research community will be significant.”

The DoD funding will provide vital resources in the realm of scientific research rooted in thin films and nanostructures of refractory metal dichalcogenides and layered materials of a semiconductor and thermoelectric material called bismuth telluride, which is often used as a topological insulator. These layered materials will be synthesized at Morgan. Subsequent highly critical stability calculations and growth kinetics modeling of the 2D materials, along with experimental device development, will be performed by JHU and APL researchers.

HEMI Fellow Muyinatu Bell Shines New Light on Photoacoustic Imaging

Muyinatu Bell wants to make surgery safer. A HEMI Fellow, assistant professor in the Department of Electrical and Computer Engineering, and director of the Photoacoustic and Ultrasonic Systems Engineering (PULSE) Lab, Bell utilizes her cross-disciplinary training to maximum effect. Her work’s potent combination of computer engineering, biomedical optics, and computer science is innovating photoacoustic imaging for better surgical tools which have a wealth of applications across surgery, cancer detection, and women’s health. These efforts have also won her a slew of recognitions including an MIT Technology Review Top 35 Innovators under 35 honor, and, in 2019, an Outstanding Young Engineer Award from the Maryland Academy of Sciences and the Maryland Science Center. Earlier this year, she was an invited Hot Topics speaker at the BiOS conference during SPIE Photonics West.

“I had a particular interest in integrating photoacoustic and ultrasound imaging systems with robotics,” says Bell who will be discussing her current research during the free SPIE.online webinar on 17 August, hosted by the Journal of Biomedical Optics. “I want to improve robotic surgery and to use robotics in new ways to enhance the type of imaging technology that we can provide. At the moment, we are developing novel signal-processing and beamforming techniques for both ultrasound and photoacoustic imaging, and we take those techniques and design novel prototypes — a specialized light-delivery system that attaches to surgical tools, for example — and we use these prototypes to improve image quality. We then integrate our innovations with commercially available ultrasound, laser, or robotic systems, creating a new system that’s the first of its kind to address a clinical challenge. We are always developing our work with the end goal of impacting patient care.”

HEMI Fellow Susanna Thon Receives NSF Career Award

Congratulations to HEMI Fellow Susanna Thon, who has been chosen by the National Science Foundation for its prestigious CAREER Award, which recognizes early-stage scholars with high levels of promise and excellence. Thon is an assistant professor in the Department of Electrical and Computer Engineering. Prof. Thon’s research is in the field of nanomaterials engineering for optoelectronic devices, with a specific focus on renewable energy conversion and storage. Her work applies techniques from nanophotonics and scalable fabrication to produce devices and materials with novel optical and electrical functionality.

Her CAREER project, “Finite-Absorption-Bandwidth Nanomaterials for Multijunction Photovoltaics and Narrow-Band Photodetectors,” has the potential to lead to a more efficient, usable, and cost-effective way of generating solar energy.

“The basic thrust of the project is, we came up with a new way to control the color of materials,” Thon said. “We drill periodic arrays of air holes into the absorbing materials called ‘photonic crystals’, and that changes how the materials absorb light. This is a way to perform ‘color tuning,’ so it is essentially a new strategy for controlling the color in these materials.”

Thon believes that these solar cells and light sensors could eventually help create a more efficient, usable, and cost-effective way of generating solar energy. She envisions a day when the cells and sensors could be made into paints that could be used on the exteriors of homes and other buildings to capture the sun’s energy, providing heating and cooling and powering appliances inside.

She predicts that much of the work on this project will focus on achieving the level of color tuning control needed to obtain optimal results—a challenge that she feels certain that she and her excellent team at Johns Hopkins can meet.

Congratulations, Prof. Thon!
