Phase-field Method in Analysis of Nanocomposite Morphological Stability
Cu-Nb multilayer nanocomposite has prospective applications in nuclear industry because of its ability to self-heal from radiation damage. The goal of the study is to find a suitable joining method for the composite to produce industrial-scale pieces, free of defects threatening the ... Read More
Use of Simulation in the Development of Next-generation Measurement Standards for Radiation Dosimetry
Calibration of field instruments used in radiation treatment clinics is currently traceable to NIST primary standards via protocols involving static, flat-field radiation beams. By contrast, radiation beams prescribed for treating cancer incorporate temporal and spatial modulation ... Read More
Simulation of Radiation Dose from Diagnostic X-ray Beams
Direct realization of absorbed dose to water in diagnostic radiation via calorimetric methods poses many challenges since the thermal signal of interest may be less than a few microKelvin. In actual biological systems or structures, like the lung, there is the additional complication of ... Read More
Phase-sensitive Microcalorimetry for Study of Low-level Radioactive Sources
Microcalorimetry for standardizing activities of radionuclide samples entails measurements of input power heat flow from the sample cell, with the radioactive sample compared to the reference cell under balanced conditions. The measurement is susceptible to noise due to drift and 1/f ... Read More
Finite Element Analysis of Photoacoustic Response from Gold Nanoparticle
Photoacoustic (PA) imaging has matured into a clinical modality for tissue imaging and functional cancer cell research. It uses a pulsed laser to irradiate a region and generate a thermally-induced acoustic pressure wave that can be collected by an ultrasound transducer. The optical ... Read More
Convective Cooling of Electronic Components
The time-dependent fluid flow and thermal interactions have been solved for transient and steady state conditions of the conjugate heat transfer problem between the natural convective flow and heat sinks composed of arrays of pins. The increased ratio of convective to conductive heat ... Read More
Chemical Reaction Under Highly Precise Microwave Irradiation
Chemical reactions conducted under microwave irradiation have high reaction rates and high selectivity, but these reaction rates are not always reproducible. To achieve reproducibility, a solid-state microwave source with an ultra precise oscillator, high power amplifier module (HPA), ... Read More
Application of COMSOL Multiphysics® Pipe Flow Module to Develop a High Flux Isotope Reactor (HFIR) System Loop Model
Oak Ridge National Laboratory’s High Flux Isotope Reactor (HFIR) is the highest flux reactor-based source of neutrons for research in the United States. Thermal and cold neutrons produced by HFIR are used to study physics, chemistry, material science, engineering, and biology. Currently, ... Read More
Advancements in Carbon Dioxide and Water Vapor Separations Using COMSOL Multiphysics®
