The data show that the shape effect in PET tumor imaging can be as large as 15% for ellipsoid phantoms with axis ratios of 2:1, volume of 1.15 cm3, and tumor-to-background activity concentration ratio of 9:1. This is ...

To develop LUAM in a methodical manner with minimal risk, a staged approach was devised whereby coupon-level mechanical testing and prototyping utilizing existing equipment was accomplished. Four key tasks have been ...

Unfortunately, embrittlement of the silicone mask was noticed during flat panel production, leading to a series of tests to determine the effect of EB irradiation on silicone mechanical properties. Using a constraining ...

Next, a modification of optofluidic fabrication is introduced to break the top-down symmetry observed in all of the original 3D particle shapes. By introducing the time dimension into our existing optofluidic fabrication ...

There is growing attention to additive manufacturing (AM) processes in industry and academia. Specifically, one metal AM process - laser powder bed fusion (LPBF) - is particularly attractive as it can directly produce ...

Although the first fuel cell was invented in 1839 by Sir William Robert Grove, practical fuel cells were not developed until the 1960’s as part of the Apollo program. Due to the high efficiency and simple energy conversion ...

Fiber-reinforced soft composites (FrSCs) are an emerging class of composites that are made up of polymeric fibers with specific material properties and hierarchical length-scales, embedded within another soft-polymer matrix. ...
