Instrum. 81, 10D529 (2010); 10.1063/1.3494379 Measurement of electron temperature and density in an argon microdischarge by laser Thomson scattering Appl.A comparison of spectroscopic and Thomson scattering measurements of electron densities and temperatures in a transient expanding plasma flow Electron temperature T, and density n, in the source region of an electron cyclotron resonance discharge have been measured by incoherent Thomson scattering of the beam from a 0.5 J yttrium aluminum garnet laser. This is the first experiment in which this technique, routinely used on fusion plasmas, has been applied to a processing plasma. Measurements were made in an argon discharge at pressures from 0.3 to 2 mTorr and microwave powers from 250 to 1000 W. Velocity distributions were measured both parallel and perpendicular to the magnetic field and a slight anisotropy of electron temperature was observed for low-pressure discharges. Temperatures in the range of l-5 eV and densities in the range of 2-10x 10" rnd3 were measured. T, and n, were found to strongly depend on pressure but only weakly on the input power and discharge magnetic field. No deviations from a Maxwellian velocity distribution were observed.

A multilayer film consisting of glucose oxidase (GOx) and(2-aminoethyl)ferrocene (2-AF) as an electron mediator has been prepared on an Au electrode with the use of glutaraldehyde as a cross-linking agent The amount of GOx and 2-AF deposited on the electrode is varied by changing the concentration of 2-AF relative to that of GOx in the preparation bath, and the highest deposition is obtained at an optimum concentration of 2-AF. Interestingly, the molar ratio of 2-AF to GOx in the film is ~10, independent of relative compositions of 2-AF to GOx in

A novel amperometric glucose sensor was fabricated in which glucose oxidase and 2-aminoethylferrocene as an electron mediator were chemically bound to self-assembled 4-aminothiophenol monolayer on gold electrode with use of glutaraldehyde as a cross linking agent. The glucose sensor prepared under optimal conditions showed sensitivities more than 30 μA cm−2 for 20 mM of glucose.

The behavior of porous apatite- and wollastonite-containing glass-ceramic (AW) in the bone marrow cavity was investigated. Cylinders of porous AW (4 mm in diameter and 20 mm long, mean porosity of 70% and mean pore diameter of 200 microm) were implanted into the bone marrow cavity of rabbit femurs, and analyzed by chronological radiograms and by scanning electron microscopy one, three, six, and 12 months later. The pores of porous AW are interconnected and homogeneously distributed, and its compressive strength is nearly equal to that of human cancellous bone. Bone formed in the pores at the center of the material by one month and bonded to the material directly. The volume of newly formed bone in the material pores reached a peak at three months, and decreased gradually after six months. The trabecular structures of AW were gradually remodeled by newly formed bone, while AW-bone bonding was maintained during bone remodeling and material absorption. AW was absorbed continuously, and at six and 12 months the residual material corresponded to about 64 and 30% of the starting material, respectively. Porous AW may therefore be useful as an absorbable bone substitute.
