Results are presented of the elemental analysis of iron ore using laser-induced breakdown spectroscopy (LIBS). Calibration curves for calcium, silicon, magnesium, aluminium, and titanium were produced. The precision ranges from ≈2 to ≈25%. The de

Laser desorption Fourier transform ion cyclotron resonance positive- and negative-ion mass spectra are presented for dimethyl 8-acetyl-3,7,12,17-tetramethylporphyrin-2,18-dipropanoate. The 248-nm laser ionization thresholds for both positive and nega

Laser-induced plasmas are highly transient phenomena, lasting for several microseconds. The lines of a plasma spectrum do not appear simultaneously, and, furthermore, they exist for a range of lifetimes. Time-resolved laser-induced breakdown spectros

Results are presented of a study of the plasma induced by the irradiation of a steel target by an excimer laser (308 nm, 28 ns, 40 mJ/pulse). Plasmas were formed in atmospheres of air, argon, nitrogen, and helium, at pressures from 0.5 Torr to 760 To

This paper discusses ceramic powders produced by the photodecomposition of chloromethylsilanes using a pulsed excimer laser operating at 193 nm. These feedstocks are cheaper and easier to handle than SiH/sub 4/, the main feedstock used in earlier wor

Binding of proteins to polystyrene plates used in enzyme linked immunosorbent assays (Elisa tests) has been improved by three different methods using UV radiation from an excimer laser. The methods studied were: i) a high fluence method, where materi

Rapid-scan Fourier transform infrared (FTIR) spectroscopy is becoming a useful method for monitoring reaction kinetics. The excimer laser has recently appeared as a source of intense UV radiation for laser-assisted photochemistry. These two tools are
