Kyle Anderson, Kerry Scott, Christina Bergonzo, Ioannis Karageorgos, Elyssia Gallagher, Venkata Tayi, Michael Butler, Jeffrey W. Hudgens
Previous reports present different models for the stabilization of the Fc—FcγRI immune complex. Although accord exists on the importance of L235 in IgG1 and some hydrophobic contacts for complex stabilization, discord exists regarding the existence of

Blood vessel-on-a-chip examines biomechanics of microvasculature

Paul Salipante, Steven D. Hudson, Styliani Alimperti
We use a three-dimensional (3D) microvascular platform to measure the elasticity and membrane permeability of the endothelial cell layer. The microfluidic platform is connected with a pneumatic pressure controller to apply hydrostatic pressure. The

Solvent-cast 3D Printing of Biodegradable Polymer Scaffolds

John Tolbert, Diana Hammerstone, Nathaniel Yuchimiuk, Jonathan Seppala, Lesley Chow
Three-dimensional (3D) printing is a popular technique to fabricate scaffolds for tissue engineering because of its ability to produce complex tissue-like architectures. Scaffolds are often 3D printed using biodegradable polymers like poly(caprolactone)

Analytical and Numerical Analyses for Two-Dimensional Stress Transfer

C H. Hsueh, P Becher, Lin-Sien H. Lum, Stephen A. Langer, W Carter
Both analytical modeling and numerical simulations were performed to analyze the stress transfer in platelet-reinforced composites in a two-dimensional sense. In the two-dimensional model, an embedded elongate plate bonded to a matrix along its length

c-Axis Oriented Epitaxial BaTiO 3 Films on (001) Si

V Vaithyanathan, J Lettieri, W Tian, A Kochhar, H Ma, A Sharan, A Vasudevarao, J. A. Aust, Y Li, Long-Qing Chen, P Zschack, Joseph Woicik
c-axis oriented epitaxial films of the ferroelectric BaTiO3 have been grown on (001) Si by reactive molecular-beam epitaxy (MBE). The orientation relationship between the film and substrate is (001) BaTiO3 // (001) Si and [100] BaTiO3 // [110] Si. The

Characterization of New 5M and 7M Polytypes of Niobia-Doped Ca 2 Ta 2 O 7

October 12, 2021

I E. Grey, Robert S. Roth, W G. Mumme, J Planes, Leonid A. Bendersky, C Li, J Chenavas
Two new calcium tantalate polytypes have been prepared in the system Ca2Ta2O7-Ca2Nb2O7. Their structures have been determined and refined using single crystal X-ray diffraction data and powder neutron diffraction data, and their dielectric properties have

Chemical Analysis of HfO 2 / Si (100) Film Systems Exposed to NH 3 Thermal Processing

October 12, 2021
Author(s)
Patrick S. Lysaght, Joseph Woicik, Daniel A. Fischer, Gennadi Bersuker, Joel Barnett, Brendan Foran, Hsing-Huang Tseng, Raj Jammy
Nitrogen incorporation in HfO2/SiO2 films utilized as high-k gate dielectric layers in advanced metal-oxide field-effect transistors (MOSFETs) has been investigated. Thin HfO2 blanket films deposited by atomic layer deposition on either SiO2 or NH3 treated
