    Notes: Abstract The electrochemical behaviour of a hydrogen/oxygen gas mixture at platinum electrodes in contact with a solid polymer electrolyte (Nafion 115) was studied in two modes: hydrogen enrichment and fuel cell. In the hydrogen enrichment (purification) mode, i/V(V being the applied voltage) characteristics were identified for the electrochemical cell arranged so that the gas mixture with varying ratios which contacts the anode was purified to pure hydrogen gas that was released at the cathode. In the fuel cell mode, V/i (V being the terminal voltage) characteristics were determined for the cell which utilized the gas mixture with varying ratio at the anode and pure oxygen at the cathode. The effect of the decrease in the mole fraction of hydrogen (χH2) on the current density or the terminal voltage was particularly severe for χH2〈0.6. The drop was analysed employing terms such as oxygen reduction current, oxygen adsorption and the change of e.m.f. (electromotive force) due to the decrease in the partial pressure of the hydrogen gas.

    Notes: Abstract The aim of this experimental study is to investigate the heat (mass) transfer of a rotating disk with an impinging circular jet. To facilitate the experiments, the naphthalene sublimation technique was employed. In order to analyze the results, measurements of the heat (mass) transfer of a stationary disk with an impinging jet and a rotating disk without jet impingement were also made. From the experimental results, it is found that the heat (mass) transfer are precisely divided into three regimes, namely the impingement dominated regime; the mixed regime and the rotation dominated regime. Correlation of Sherwood number of a rotating disk with jet impingement is also proposed in the present work.

    Notes: Abstract  The precision of transferred patterns are highly dependent on the quality of the mask in deep x-ray lithography. Many parameters, such as the critical energy of the synchrotron light, beamline optics and even the microstructure to be exposed should be considered in mask design. In this paper, the design rules and the boundary conditions for deep x-ray mask are discussed in general. The method of making a precision, multilayer mask using UV lithography technique is also described.

    Notes: Summary Conditions for the synthesis of synthetic peptide combinatorial libraries (SPCLs) from mixtures of amino acids were explored. In a one-pot synthesis, the effect of the starting concentrations of amino acids on the resulting library composition was studied, and the optimum balance of amino acids was determined. Protein sequencing, MALDI-TOF, and amino acid analysis were used for the evaluation of the libraries, and their relative merits are discussed. The effects of continuous-flow automated synthesis instrumentation in conjunction with polyethylene glycol-polystyrene (PEG-PS) graft supports and various cleavage cocktails on the successful synthesis of SPCLs were examined.

    Notes: Abstract  This paper describes the micromachining program status of the micromachining laboratory at the SRRC. A preliminary LIGA process has been established. Many joint projects with local and foreign institutes to develop devices for domestic industries have been started. The interests in the application of the LIGA technology is continuously growing in Taiwan. Two-millimeter ultra-deep microstructures have been achieved.

    Notes: Abstract  The centromere of maize chromosome 4 was previously localized to a 26-cM interval using molecular markers and B-A translocations. The objective of the present study was to refine the placement of the centromere using secondary trisomics. Two independently isolated secondary trisomics (having an isochromosome plus two normal homologs) for 4S were recovered. RFLP analysis of populations segregating for them placed the centromere of chromosome 4 between bnl15.45 and bnl7.20, two RFLP loci that are 5.4-cM apart on the UMC map and 11.5-cM apart on the BNL map.

    Notes: Abstract A new species of harpacticoid copepod, Neocervinia itoi (Cerviniidae), is described on the basis of females and copepodids collected from the Hatsushima cold-seep site in Sagami Bay, Japan. It is morphologically very close to its deep-sea congeners N. tenuicauda (Brotskaya, 1963) and N. unisetosa (Montagna, 1981). The new species differs primarily in the segmentation of the antennule and the endopod of both mandible and maxilliped, and in form and shape of the setae on leg 5. The presence of sensillar structures on the proximal part of the antennule is discussed. A key to the species of Neocervinia is presented.

    Notes: Abstract Ultramicrotomy is being used routinely as a sample preparation technique for transmission electron microscopy (TEM). TEM study of thin sections of a diketone-bis-benzocyclobutene composite reinforced with Celion (trademark of BASF Co.) carbon fibre revealed two types of periodic crack in the fibre. Coarse cracks were due to bending at knife tip in the early stage of the ultramicrotomy. Also, very fine cracks were observed near the fibre–matrix interface and believed to have been induced by the shear lags between the fibre and the matrix. A simple analysis indicated that the coarse and fine crack spacings could be used to obtain the compressive strength of the fibre and the ultimate shear stress at the fibre–matrix interface, respectively. The combination of ultramicrotomy and TEM provides a useful tool to explore the mechanical properties of a composite material on the submicrometre scale, in addition to the other microstructural and compositional information accessible by TEM.

    Notes: Abstract Protective coatings of CVD diamond have been bonded to infrared-transmitting optical windows of ZnSe with As-Se-S system chalcogenide glasses of which the refractive index is made to closely match that of diamond by the “optical brazing” process. To select optimal composition in the As-Se-S system, the Tg, Ts, reflective index and infrared-transmittance of the glass samples were measured. Measurement of transmittance with a Fourier transform infrared spectrometer after the brazing process confirmed that scattering losses were greatly reduced. Infrared transmittance of ZnSe windows with a thin film diamond coating bonded to chalcogenide glass was about 63%.
