Broadband, High-Frequency Permittivity Characterization for Epitaxial Ba1-xSrxTiO3 Composition-Spread Thin Films

June 24, 2021
Author(s)
Eric J. Marksz, Aaron Hagerstrom, Jasper A. Drisko, James Booth, Nate Orloff, Xiaohang Zhang, Naila Al Hasan, Justin Pearson, Ichiro Takeuchi
Next-generation millimeter-wave (> 30 GHz) telecommunications electronics must be compact, energy efficient, and have good thermal management. Tunable materials may play a role in meeting these requirements for millimeter-wave front-ends, but there are few

Effects of aluminum content on thermoelectric performance of Al CoCrFeNi high-entropy alloys

June 15, 2021
Author(s)
Md Abdullah Al Hasan, Jiaqi Wang, Seungha Shin, Dustin A. Gilbert, Peter K. Liaw, Nan Tang, W. L. N. C. Liyanage, Louis Santodonato, Lisa Debeer-Schmitt, Nicholas Butch
Introducing a non-regular distribution in the mass and bonding by including distinctly different elements can reduce the phonon transport even within structurally well-ordered materials. These distributions are a quality of all high-entropy alloys (HEAs)

Preservative Induced Polysorbate 80 Micelle Aggregation

June 1, 2021
Author(s)
Peter H. Gilbert, Zhenhuan Zhang, Ken K. Qian, David P. Allen, Norman J. Wagner, Yun Liu
Small angle neutron scattering (SANS) studies of a model pharmaceutical formulation reveal how formulation stability depends on the compatibility of individual components. Solutions of two common protein formulation excipients, polysorbate 80 (PS80), a

Late Stage Domain Coarsening Dynamics of Lamellar Block Copolymers

May 26, 2021
Author(s)
Jack F. Douglas, Maninderjeet Singh, Wenjie Wu, Vinay Nuka, Joseph Strzalka, Alamgir Karim
Block copolymer (BCP) phase separation is an intriguing phenomenon whose dynamics can be expected to differ significantly from that of the polymer blends due to constraint of chain connectivity that limits the ultimate scale of phase separation and the

Fabrication of 3D Printed Hydroxyapatite Composite Scaffolds for Bone Regeneration

May 19, 2021
Author(s)
Yoontae Kim, Eun-Jin Lee, Albert Davydov, Stanislav Frakhtbeyen, Jonathan Seppala, Laurence Chow, Tagaki Shozo, Stella Alimperti
Additive biomanufacturing has been adapted in a wide variety of biomedical and tissue engineering applications, including orthopedics. The ability to print biocompatible, patient-specific geometries with controlled porosity, mechanical strength has made

Graded Magnetic Materials

May 17, 2021
Author(s)
Lorenzo Fallarino, Brian Kirby, Eric E. Fullerton
Graded magnetic materials represent a promising new avenue in modern material science from both fundamental and application points of view. Over the course of the last few years, remarkable results have been obtained in (epitaxial) heterostructures based
