PECVD silicon nitride photonic wire waveguides have been fabricated in a CMOS pilot line. Both clad and unclad single mode wire waveguides were measured at 1⁄4 532, 780, and 900 nm, respectively. The dependence of loss on wire width, wavelength, and cladding is discussed in detail. Cladded multimode and singlemode waveguides show a loss well below 1 dB/cm(More)
Water hyacinth (Eichhornia crassipes), an aquatic weed common to the subtropic/tropical regions, was utilized as an inexpensive lignocellulosic substrate for production of cellulase by Trichoderma reesei. The effects of process parameters like substrate pretreatment, substrate concentration, initial medium pH, mode of inoculation, and incubation temperature(More)
The present study aims at deposition of zinc phosphate coatings with the incorporation 9 of nano Titanium dioxide particles by chemical phosphating method. Zinc phosphate coatings were 10 developed on low carbon steel by using nano TiO2 in the standard phosphating bath. The Coated 11 low carbon steel samples were assessed for corrosion studies using(More)
