We have investigated the stimulated Brillouin scattering (SBS) threshold of various types of fibers both theoretically and experimentally by utilizing Brillouin optical-time-domain reflectometer. The measured deviations of SBS threshold of less than 0 1 dB compared with the conventional method are demonstrated for standard single-mode fiber (SMF),(More)
2,4,6-Trichlorophenol (TCP) sulfonate esters undergo effective aminolysis under conventional heating and microwave irradiation; the reactivity of these species is such that chemoselective transformations of PFP sulfonate esters can be achieved.
A method is presented for the analysis of (2,4-dichlorophenoxy)acetic acid (2,4-D) in commercial formulations, together with concurrent detection and quantitation of related compounds. The method is based on direct gas-liquid chromatographic (GLC) analysis of the formulation to estimate the various esters present, and on an analysis of the total 2,4-D(More)
