Abstract
Toxic gases are used in different types of industries and thus, present a potential health hazard. Therefore, highly sensitive gas sensing materials are essential for the safety of those operating in their environments. A process involving electrospinning polymer solutions impregnated with transition metal ions are developed to yield nanofibers that are annealed to form graphitic carbon / nickel nanoparticle-based fibers for gas sensing applications. The performance of these gas sensors is strongly related to the ability to control the material parameters of the active material. As the formation of these nanostructures, which nucleate within solid carbon scaffolds, have not been investigated, the growth mechanisms are look to understand in order to exert control over the resulting material. Evaluation of these growth mechanisms are conducted through a combination of thermogravimetric analysis with mass spectrometry (TGA-MS), x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and x-ray photoelectron spectroscopy (XPS) and reveal nucleation of nickel at the onset of the polymer scaffold decomposition with subsequent growth processes, including surface diffusion, aggregation, coalescence and evaporation condensation, that are activated at different temperatures. Gas sensing experiments conducted on analyte gases demonstrate good sensitivity and response times, and significant potential for use in other energy and environmental applications.

Abstract
A theoretical study of the time-of-flight (TOF) distributions under pulsed laser evaporation in vacuum has been performed. A database of TOF distributions has been calculated by the direct simulation Monte Carlo (DSMC) method. It is shown that describing experimental TOF signals through the use of the calculated TOF database combined with a simple analysis of evaporation allows determining the irradiated surface temperature and the rate of evaporation. Analysis of experimental TOF distributions under laser ablation of niobium, copper, and graphite has been performed, with the evaluated surface temperature being well agreed with results of the thermal model calculations. General empirical dependences are proposed, which allow indentifying the regime of the laser induced thermal ablation from the TOF distributions for neutral particles without invoking the DSMC-calculated database.
