Optimizing graphene oxide reduction via laser irradiation
(East Carolina University, 2017-01-04)
The present report discusses a single step method to reduce graphene oxide via laser irradiation. A computer numerically controlled laser engraver equipped with a 450nm laser diode was engineered to conduct this research. ...
A NEW ELECTRON SPECTROSCOPY SYSTEM FOR MEASURING ELECTRON EMISSION FROM FAST ION INTERACTIONS WITH ATOMIC, MOLECULAR, AND CONDENSED PHASE TARGETS
(East Carolina University, 2016-07-25)
A new electron spectroscopy system has been developed for measuring electron emission from gas and solid targets induced by fast ion impact. This system uses an ultrahigh-vacuum compatible cylindrical deflector analyzer, ...
Feasibility Study of Dual Energy Radiographic Imaging for Target Localization in Radiotherapy for Lung Tumors
(2014)
Purpose
Dual-energy (DE) radiographic imaging improves tissue discrimination by separating soft from hard tissues in the acquired images. This study was to establish a mathematic model of DE imaging based on intrinsic ...
A new assessment model for tumor heterogeneity analysis with [18]F-FDG PET images
(2016-01)
It has been shown that the intratumor heterogeneity can be characterized with quantitative analysis of the [18]F-FDG PET image data. The existing models employ multiple parameters for feature extraction which makes it ...
Resolving power of diffraction imaging with an objective: a numerical study
(2017-05)
Diffraction imaging in the far-field can detect 3D morphological features of an object for its coherent nature. We describe methods for accurate calculation and analysis of diffraction images of scatterers of single and ...
A solution method determining the effect of spin upon gravitational effects in the surroundings of a black hole
(East Carolina University, 2017-12-12)
Using the theory of General Relativity and quasi-normal modes (QNMs) from the Teukolsky equation as a source of quasi-periodic oscillations (QPOs) from black holes provides information about black hole mass and spin. This ...
