Large Molecular Weight Nitroxide Biradicals Providing Efficient Dynamic Nuclear Polarization at Temperatures up to 200 K

David Lyndon Emsley, Aaron James Rossini

A series of seven functionalized nitroxide biradicals (the bTbK biradical and six derivatives) are investigated as exogenous polarization sources for dynamic nuclear polarization (DNP) solid-state NMR at 9.4 T and with ca. 100 K sample temperatures. The im ...

Two-Phase Flow Boiling in a Single Layer of Future High-Performance 3D Stacked Computer Chips

John Richard Thome, Navid Borhani, Sylwia Szczukiewicz

The present study focuses on an experimental investigation of two-phase flow boiling in a silicon multi-microchannel evaporator, which emulates a single layer of a 3D stacked computer chip. The micro-evaporator is comprised of 67 parallel channels, each ha ...

The influence of sodium and potassium hydroxide on volume changes in cementitious materials

Karen Scrivener, Aditya Kumar

This research investigates the influence of alkali hydroxides on unrestrained volume changes. A detailed multi-method approach is used to characterize the progress of cement hydration, autogenous and drying volume changes (i.e., shrinkage), autogenous RH d ...

Biodegradable polylactide/hydroxyapatite nanocomposite foam scaffolds for bone tissue engineering applications

Pierre-Etienne Bourban, John Christopher Plummer, Claire Diane Delabarde

Supercritical carbon dioxide processing of poly--lactide (PLLA)/hydroxyapatite (nHA) nanocomposites was investigated as a means to prepare foams suitable as scaffolds in bone tissue engineering applications. For given foaming parameters, addition of nHA to ...

Two-phase frictional pressure drops in U-bends and contiguous straight tubes for different refrigerants, orientations, tube, and bend diameters: Part 2. New models (RP-1444)

John Richard Thome, Ricardo Lima

In the first part of this article (Silva Lima and Thome 2012b), new experimental frictional pressure drop data in U-bends were presented and discussed. The experimental data were obtained for R410A and R134a at two saturation temperatures (5 degrees C and ...

Capillarity in pressure infiltration: improvements in characterization of high-temperature systems

Andreas Mortensen, Raphaël Charvet, Ludger Weber, Alain Léger, Willy Dufour, Claudio Bacciarini, Noelia Rojo Calderon

In the pressure infiltration of metal matrix composites, molten metal is injected under external pressure into a porous preform of the reinforcing material. Equilibrium capillary parameters characterizing wetting for this process are summarized in plots of ...

Two-phase frictional pressure drops in U-bends and contiguous straight tubes for different refrigerants, orientations, tube, and bend diameters: Part 1. Experimental results (RP-1444)

John Richard Thome, Ricardo Lima

Over the years, much research has been conducted on two-phase flows in straight tubes because these tend, in length, to be predominant in two-phase systems. However, two-phase heat exchangers can also have singularity elements, where the most common type i ...

Boiling on a Tube Bundle: Part I-Flow Visualization and Onset of Dryout

John Richard Thome, Navid Borhani, Eugene van Rooyen, Francesco Agostini

A novel visualization method was developed and implemented in a refrigerant-flooded evaporator tube bundle. Specifically, a method to visualize the two-phase flow inside plain tube bundles was developed using a dummy tube with a tubular glass section for v ...

Modeling W-V and W-Ta Alloys for Fusion Applications: Phase Stability, Short-Range Order and Point Defect Properties

Nadine Baluc

We have performed density-functional theory (DFT) calculations of phase stability, formation energies of radiation defects in tungsten-based binaries W-Ta and W-V. These alloys are candidate for DEMO divertor applications because of their high melting poin ...
