Infrared (IR) spectroscopy is used extensively to characterize the chemical composition of trace evidence such as paints, fibers and adhesives as well as seized drugs and related chemicals. We have recently introduced the Thermo ScientificTM iSTM50 ATR module, a novel, extended-range attenuated total reflectance (ATR) module that is integrated into the NicoletTM iS50 FT-IR spectrometer. This in...

©2011 IEEE Plotting the individual components is shown in Fig. 11. Adding the pulses gives the solution for V 10, t 2 shown in Fig. 12. All of the results of the above examples were validated using the PSPICE circuit analysis computer program. Use of the exact lossless transmission line model in PSPICE for more complicated lossless transmission-line problems is highly recommended [1]. VI. Refer...

We report a widely tunable single-frequency linear-cavity erbium-doped fiber laser covering both the conventional wavelength band (C-band) and the long wavelength band (L-band). The laser has low threshold, high slope efficiency and high signal-to-noise radio. A large tuning range of over 100 nm is realized by optimization of the active fiber length.

In this work the 3D extrusion printing fabrication process for intricate structures is examined. Required support material normally is removed by brute force water jetting. We investigated the chemical dissolution of Fullcure 705 support material while minimally affecting Fullcure 720 structural material. From several solvents ethanol turned out to be the best with respect to selectivity and di...

High-strength low alloy steels (HSLA) have been designed to replace high-yield (HY) strength steels in naval applications involving impact loading as the latter, which contain more carbon, require complicated welding processes. The critical role of HSLA-100 steel requires achieving an accurate understanding of its behavior under dynamic loading. Accordingly, in this paper, we experimentally inv...
