Under the assistance of magnetic field, the electron cyclotron resonance effect generates a high density plasma in a large spaceregion This offers an beneficial condition for large area diamond films deposition. By using a mixture of methane (CH4) and hydrogen (H2), a diamond film of 5 cm diameter has been grown on silicon substrate under the pressure about 3 Torr which is considerably lower than the pressure in all other methods recently used. In view of the spacial extent of the plasma, we see that it is possible to further increase the area of deposited diamond film. The growth condition of diamond film in gas phase deposition under the pressure of 0.5 to 50 Torr has been discussed on the basis of analyzing the optical emission spectrum of the plasma.

The sheet resistance Rs and tmperature coefficient o f resistance (TCR) ci (25-100°C) 'of amorphous NiggSi15B17 f i l m s have been measured. The structure of f i h s with Rs between 80-550R/sq. are more stable and have a lower TCR (10-6K-1-10-5K-1). may change I n t h i s mnge of Rs, TCR its sign, and the activation energy is much larger.

To solve black spot which is produced during the process of attaching GOS to TFT panel via OCA (optical clear adhesive), we investigated the difference of OCA from two suppliers. The result shows black spot has strong positive correlation with adhesive thickness. By monitoring thickness by SEM in volume production, we solve this problem completely.

BackgroundRoot-knot nematode Meloidogyne incognita infects root systems of many crops resulting in huge decrease of crop production. Nematicidal microorganisms provides a safe and effective strategy to control M. incognita infection. In order to find more microorganisms with high activity and new nematicidal metabolites, we collected the M. incognita infected tobacco rhizosphere soils (RNI) and non-infected tobacco rhizosphere soils (NS), and investigated their microbial community and network via metagenomics and metabolomics analysis. ResultsMicrobial networks of RNI soils were very different from the NS soils. Many nematicidal microorganisms were enriched in the NS soils, including some isolates such as Aspergillus , Achromobacter , Acinetobacter , Bacillus , Burkholderia , Comamonas , Enterobacter , Lysobacter , Microbacterium , Paenibacillus , Pantoea , Pseudomonas , Streptomyces and Variovorax. Enzymes analysis showed these nematicidal microorganisms can produce proteases, chitinase and lipases. The functions genes belonging to pathways of secondary metabolites biosynthesis and carbohydrate transport and metabolism were overrepresented in the rhizophere microbiota of NS soils comparing with the RNI soils. 102 metabolites contents were significantly different between the RNI and NS rhizosphere microbiota. 35 metabolites were overrepresented in the NS soils comparing the RNI samples, including acetophenone. Acetophenone showed high nematicidal (LC 50 = 0.66 μg/ml) and avoidance activity against M. incognita . A isolate of Bacillus amyloliquefaciens W1 with production of acetophenone can kill 98.8% of M . incognita . ConclusionsIn general, the rhizophere microbiota of NS soils could produce volatile materials, multiple enzymes and secondary metabolites against nematode. Collectively, the microbiota of NS and RNI rhizophere differed significantly in microbial network structure, community composition, function genes and metabolites. Collectively, combination of multi-omics analysis and culture-dependent technology is powerful for finding nematicidal microorganisms and metabolites from soil.
