    Notes: X-ray photoelectron spectroscopy and Auger electron spectroscopy studies were performed for determining the chemical composition, compositional depth profile, and the chemical bondings of ferroelectric (Pb,La) TiO3 thin films deposited by a multi-ion-beam reactive cosputtering technique. It was found that the chemical composition of the films and the chemical bondings of lead in the near surface region are different from those in the "bulk'' region of the films. The films are Pb enriched and the lead atoms exist mainly in the forms of PbOads (i.e., oxygen-chemisorbed lead) and PbTiO3 in the near surface region, whereas in the bulk region, the chemical composition is in good agreement with stoichiometry and lead atoms exist in the form of PbTiO3. It is believed that the effect of Pb enrichment in the near surface regions is an intrinsic phenomenon of lead-contained thin films, which may be attributable to the oxygen-chemisorbed lead.

    Linkage mapping of microdissected clones from distal mouse chromosome 16 (1996)

    Notes: Abstract A total of 38 unique segments generated by microdissection of mouse chromosome 16 (MMU16), sequence independent amplification (SIA) and cloning were sequentially mapped on the distal portion of the chromosome with two mouse backross panels. Some reference markers from other sources were retyped in the panels and results integrated with those for our microdissected DNA segments. The clone map is most highly refined in its distal portion, which stretches from reference marker D16Mit71 to D16Mit5, and the highest density of clones is in the region defined by markers D16Mit5 and D16Mit141. This map on distal mouse chromosome 16 should be a useful tool for the mouse genome project and for studies of genes in the region.

    Analysis of region-specific library constructed by sequence-independent amplification of microdissected fragments surrounding weaver (wv) gene on mouse chromosome 16 (1994)

    Notes: Abstract The C3−C4 region of mouse chromosome 16 was microdissected and amplified directly by sequence-independent amplification (SIA). The SIA product was proved to originate from the microdissected region by fluorescence in situ hybridization (FISH) and was cloned into the PCR II vector (mean insert size 506 bp). Colony hybridization showed that about 59% of the clones contained either unique or low copy number sequences. Southern blot analysis of 100 unique clones demonstrated that 50 clones hybridized with single (33 clones) or multiple (17 clones) bands on blots of DNA from a hamster-mouse hybrid cell line that contains mouse chromosome 16, 13 clones hybridized with mouse but not with the hamster-mouse hybrid DNA, 19 clones contained repetitive sequences, and the remaining 18 clones failed to yield bands. One third of the 100 unique clones hybridized to human genomic DNA. Thirty-three clones were sequenced. None of them was found in GenBank. Our results demonstrate that this relatively simple method of microdissection and cloning can produce a library of good quality.

    Notes: Abstract A series of new types of semiconducting ceramic gas-sensing materials, Al2O3-based semiconducting ceramics, have been invented. Hydrogen and methane gas sensors have been made from these materials with different metal oxide additives. These gas sensors have various advantages, such as very good gas selectivity, nearly linear relationship between sensitivity and gas concentration, lower operating temperature, fast recovery time, and good anti-humidity property. The preparation and properties of these semiconducting ceramic gas sensors are presented in this paper.
