A TiN/HfN-coated tool (THN-HF(L)) was developed to improve the processing efficiency of machining austenitic stainless steel. Using scratch tests, this tool was compared with other film-coated tools, and its critical load showed the highest value. The THN-HF(L) tool, whose film was formed in the low bias voltage condition, has a longer tool life than conventional tools. In high-speed cutting (4 or 5 m/s), its tool life is over 20 km. Even though the THN-HF(L) tool's cutting distance surpasses that of conventional tools, adhesion is controlled, and flaking of the film coating on the cutting edge is not observed.

Since its emergence in April 2009, pandemic influenza A virus H1N1 (H1N1 pdm), a new type of influenza A virus with a triple-reassortant genome, has spread throughout the world. Initial attempts to diagnose the infection in patients using immunochromatography (IC) relied on test kits developed for seasonal influenza A and B viruses, many of which proved significantly less sensitive to H1N1 pdm. Here, we prepared monoclonal antibodies that react with H1N1 pdm but not seasonal influenza A (H1N1 and H3N2) or B viruses. Using two of these antibodies, one recognizing viral hemagglutinin (HA) and the other recognizing nucleoprotein (NP), we developed kits for the specific detection of H1N1 pdm and tested them using clinical specimens of nasal wash fluid or nasopharyngeal fluid from patients with influenza-like illnesses. The specificities of both IC test kits were very high (93% for the HA kit, 100% for the NP kit). The test sensitivities for detection of H1N1 pdm were 85.5% with the anti-NP antibody, 49.4% with the anti-HA antibody, and 79.5% with a commercially available influenza A virus detection assay. Use of the anti-NP antibody could allow the rapid and accurate diagnosis of H1N1 pdm infections. Copyright © 2011, American Society for Microbiology. All Rights Reserved.

Pd nanoparticles exhibit the abnormal behavior of the Pd lattice expanding as the size of the Pd nanoparticles decreases. We measured extended X-ray absorption fine structure of poly(N-vinyl-2-pyrrolidone)-protected Pd nanoparticles and confirmed that the Pd-Pd bond distance in small Pd nanoparticles with a diameter of less than 3 nm was elongated by 2% compared with that in Pd foil. The origin of the unusual bond elongation was discussed. © 2015 The Chemical Society of Japan.
