High-Enthalpy Test Environments, Flow Modeling and in Situ Diagnostics for Characterizing Ultra-High Temperature Ceramics
We describe the test environments generated by two types of these ground test facilities – subsonic inductively coupled plasma tunnels and supersonic arc-jet tunnels – and discuss the important roles…

Synthesis of Carbon-Rich Hafnia Thin Films By Pulsed Laser Deposition
We explored direct synthesis of carbon-rich hafnia, which is known to form as a compact interlayer in the oxide scales of oxidized hafnium carbide.

Material Property Requirements for Analysis and Design of Uhtc Components in Hypersonic Applications
We explain the nature of the analyses, highlight the essential material properties that are required and why they are important, and describe the impact of property accuracy and uncertainty on…

Noninvasive Electrical Detection of Electron Spin Dynamics at the N Atom in N@C60
Here we use the Keldysh non-equilibrium Green’s function and establish a microscopic description of how spin dynamics, including resonance and relaxation, can manifest itself in the device conductance.

Load-Deformation Behavior of Nitinol Stents
In the work reported here, testing devices were designed and constructed to measure loads in stents undergoing tensile, bending, and torsional deformations.

7.2: High-Field Deuterium Ion Sources for Neutron Generators
We are facilitating the deployment of portable active neutron interrogation systems for field detection applications by developing a new atomic deuterium ion source for compact, accelerator-driven neutron generators.

Direct Detection of NO Produced By High-Temperature Surface-Catalyzed Atom Recombination
The surface-catalytic recombination of oxygen and nitrogen atoms to form nitric oxide was confirmed by the direct detection of product NO molecules, using single-photon laser-induced fluorescence spectroscopy.

Near-Ultraviolet and Blue Spectral Observations of Sprites in the 320-460 Nm Region: N(2) (2PG) Emissions
A near-ultraviolet (NUV) spectrograph (320–460 nm) was flown on the EXL98 aircraft sprite observation campaign during July 1998.

A New Look at Low-Energy Nuclear Reaction (Lenr) Research: a Response to Shanahan
These issues are addressed by the researchers who conducted the original work discussed in the Krivit and Marwan (K&M) review paper.

Studies of the Phosphorescence of Polycrystalline Hafnia
Persistent phosphorescence induced by ultraviolet light in polycrystalline HfO2 and enhancement of the phosphorescence by sintering are investigated.

The Effect of Stereochemistry on the Thermodynamic Characteristics of the Binding of Fenoterol Stereoisomers to the Beta(2)-Adrenoceptor
The binding thermodynamics of the stereoisomers of fenoterol, (R,R′)-, (S,S′)-, (R,S′)-, and (S,R′)-fenoterol, to the β2-adrenergic receptor (β2-AR) have been determined.
