Time-Domain Near-Infrared Spectroscopy and Imaging: A Review

open access: yesApplied Sciences, 2019
This article reviews the past and current statuses of time-domain near-infrared spectroscopy (TD-NIRS) and imaging. Although time-domain technology is not yet widely employed due to its drawbacks of being cumbersome, bulky, and very expensive compared to

Real‐Time Characterization of Polypropylene Jet Dynamics in Melt Electrospinning Using Laser Diffraction and Image Analysis

open access: yesAdvanced Engineering Materials, EarlyView.
This study uses real‐time laser diffraction image analysis to quantify fiber diameter changes and whipping behavior from the nozzle to the collector under varying electric field conditions. By capturing diffraction (scattering) intensity changes and bending angles, melt jet and whipping behavior are accurately assessed, supporting melt electrospinning ...

HomER: a review of time-series analysis methods for near-infrared spectroscopy of the brain.

open access: yesApplied Optics, 2009
Near-infrared spectroscopy (NIRS) is a noninvasive neuroimaging tool for studying evoked hemodynamic changes within the brain. By this technique, changes in the optical absorption of light are recorded over time and are used to estimate the functionally ...

Near-infrared LIF spectroscopy of HfF [PDF]

open access: yesJournal of Molecular Spectroscopy, 2012
The molecular ion HfF$^+$ is the chosen species for a JILA experiment to measure the electron electric dipole moment (eEDM). Detailed knowledge of the spectrum of HfF is crucial to prepare HfF$^+$ in a state suitable for performing an eEDM measurement\cite{Leanhardt}.

Sol–Gel Synthesis of Ca2.5Ag0.3Sm0.2Co4O9 Semiconducting Materials for Thermoelectric Applications in Aerospace Systems

open access: yesAdvanced Engineering Materials, EarlyView.
Ca2.5Ag0.3Sm0.2Co4O9 semiconductor materials are synthesized and produced in this study using the sol–gel and cold pressing techniques for thermoelectric generator applications. As template samples are added, the Seebeck coefficient and power factor values rise, peaking at 800 °C for Ca2.5Ag0.3Sm0.2Co4O9 at 274.47 μV K−1 and 0.58 mW mK−2, respectively.
