Microstructure of 5keV gold-implanted polydimethylsiloxane

Microstructure of 5 keV gold-implanted polydimethylsiloxane

Solution processed polydimethylsiloxane/gold nanostar flexible substrates for plasmonic sensing.

Gold nanostars can display tunable optical properties in the visible and near IR, which lead to strong electromagnetic field enhancement at their tips. We report generalized application of gold nanostars for ultrasensitive identification of molecules, based on both localized surface plasmon resonance (LSPR) and surface enhanced Raman scattering (SERS). We address the requirements of plasmonic s...

Ferromagnetism and microstructure in Cr implanted p-type (100) silicon

The magnetic properties and microstructure of p-type Si (100) implanted with 1.0 × 1015 cm−2 of Cr ions at 200 keV have been investigated by a superconducting quantum interference device (SQUID) magnetometer, scanning electron microscope (SEM) and transmission electron microscopy (TEM). The magnetic hysteresis loops and saturation magnetization of 0.67–0.75 emu/g in a wide temperature range are...

Microstructure and Thermal Stability of Fe, Ti, and Ag Implanted Yttria-Stabilized Zirconia

Yttria-stabilized zirconia (YSZ) was implanted with 15 keV Fe or Ti ions up to a dose of 8 x 1016 at cm -2. The resulting "dopant" concentrations exceeded the concentrations corresponding to the equilibrium solid solubility of Fe2Oa or TiO2 in YSZ. During oxidation in air at 400 ° C, the Fe and Ti concentration in the outermost surface layer increased even further until a surface layer was form...

Graded Microstructure and Mechanical Performance of Ti/N-Implanted M50 Steel with Polyenergy

M50 bearing steels were alternately implanted with Ti⁺ and N⁺ ions using solid and gas ion sources of implantation system, respectively. N-implantation was carried out at an energy of about 80 keV and a fluence of 2 × 1017 ions/cm², and Ti-implantation at an energy of about 40-90 keV and a fluence of 2 × 1017 ions/cm². The microstructures of modification layers were analyzed by grazing-incidenc...
