    Notes:
    A multipole magnetic field was used to increase the ion density of an inductively coupled rf (13.5 MHZ) argon plasma for ionized magnetron sputtering of copper (Cu). Langmuir probe measurements showed an increase of plasma density over a factor of 2 with the application of the magnetic field. At an argon pressure of 15 mTorr and a rf power of 600 W, an ion density of 1.2×1012 ions/cm3 was achieved. When this plasma was applied to ionize the magnetron sputtered Cu vapor, a high emission intensity ratio from the Cu+ ion line to the Cu neutral line was observed from the optical emission spectroscopy, suggesting a high ionization fraction for the sputtered Cu vapor. © 1997 American Institute of Physics.

    Abstract The hardness, elastic modulus, and elastic recovery of nanostructured boride/nitride films 1–2 µm thick have been investigated by the nanoindentation technique under the maximum loads over a wide range (from 5 to 100 mN). It is demonstrated that only the hardness parameters remain constant at small loads (5–30 mN). The data obtained are discussed and compared with the parameters determined by other methods.

    Notes:
    Abstract Plasma source ion implantation (PSII) is a technique for modifying stafaces that places the object to he modified directly into a plasma and then negatively pulse biases the object so as to implant positive ions. If the voltage is high enough, X-rays can he generated by electrons that are also accelerated by the pulse. This work describes techniques for imaging and characterizing the X-rays A pinhole camera was used to image the X-rays being emitted as electrons collided with surfaces in the chamber. The images show that X-rays are generated at the chamber walls and near the target. The time dependence of these X-rays during each pulse was examined using a PIN diode X-ray detector. Then, using another X-ray sensor and pulseheight analyzer, the spectra of the emitted X-rays was determined. The object is to relate the X-ray intensity and spectrum to the temporal and spatial values of the implantation dose so that it may he used as a process monitor and a control sensor.

    Notes:
    Summary In previous studies, oxidants such as hydrogen peroxide (H2O2) or hydroperoxy fatty acids were shown to induce apoptosis in the CEM human T cell line as demonstrated by the cleavage of cellular DNA into a ∼ 180-base pair “ladder”. Oxidant-induced DNA fragmentation was detectable within 3 h and inhibitable by various antioxidants. In the present study, apoptosis is shown to also be induced by the addition of low doses (0.1–3 mM) of N-acetyl-L-cysteine (NAC), reduced glutathione (GSH) or cysteine. By contrast, higher concentrations (≥10 mM) of the same thiols displayed a paradoxical lack of toxicity. Thiol-induced apoptosis was completely prevented by the addition of BAPTA-AM, an intracellular calcium chelator, or by simultaneous treatment with 5 mM pyruvate which forms a thiazolidine complex with sulfhydryl compounds. Catalase or glutathione peroxidase, but not Superoxide dismutase, protected the cells from thiol-induced apoptosis demonstrating a role for H2O2. The ability of thiol compounds to either evoke or prevent oxidative stress implies a unique role for these agents in the control of apoptosis in lymphoid cells.
