Design and Manufacture of a Functional 3D-Printed Stirling Engine: A Case Study Involving Bound Metal Deposition of 17-4 PH

Campbell Q., Filiault M., Rooney K., Belding J., Ellis B.D., University of Maine, US

Bound metal deposition (BMD) is a recently commercialized additive manufacturing of metal (AMM) process in which metal powder-binder composites are printed, debound, and sintered. Although potentially offering significant costs savings compared to traditional AMM process, [...]

Thousand-fold speedup of discrete-particle-based computer-aided reactor design and scale-up

Lu L., Benyahia S., National Energy Technology Laboratory, US

Particulate matter is the second most manipulated material in industry after water and has been observed and studied by scientists and engineers since the earliest of human civilization. In fact, we commonly distinguish between the [...]

Leveraging the Nation’s Nanotechnology Research Centers: True interdisciplinary buildings foster a seamless transition from lab bench to consumer

Soueid A., Adams G., Schaeffer M., Riojas S., HDR Architecture, Inc., US

Successfully fostering emerging technologies requires diligence in continually assessing and evolving best practices resulting in process improvements. While nanotechnology is in many ways still considered an emerging field, it is rapidly becoming the corner stone [...]

Consistency of compact MOSFET models with the Pao-Sah formulation: consequences for small-signal analysis

Galup-Montoro C., Schneider M.C., Cunha A.I.A., Federal University of Santa Catarina, BR

Compact models for the MOSFET are based on the decomposition of the two-dimensional problem into two one-dimensional problems. Since a compact MOSFET model core consists of an input voltage equation, and an output current equation, [...]
