Aerosol–Cloud Interaction at the Summit of Mt. Fuji, Japan: Factors Influencing Cloud Droplet Number Concentrations

Autor: Yoko Iwamoto, Ayami Watanabe, Ryota Kataoka, Mitsuo Uematsu, Kazuhiko Miura

Publikováno v: Applied Sciences, Vol 11, Iss 18, p 8439 (2021)

To investigate interactions between aerosols and clouds, the size and number concentrations of the cloud condensation nuclei (CCN) and the cloud droplets (CDs) were measured at the summit of Mt. Fuji (altitude 3776 m), Japan. The CCN number concentra

Wear reduction effect by applying DLC to sliding components of air-conditioning compressor

Autor: Yoshinori MORI, Yasutaka ITO, Yasuo YOSHII, Norihisa WATANABE, Kazuhiko MIURA

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 85, Iss 880, Pp 19-00297-19-00297 (2019)

DLC (Diamond-Like Carbon) has excellent tribological properties such as high hardness, low friction and high wear resistance. It is widely applied in industrial field. In order to prevent excessive wear, DLC is also applied to the vane which is the m

Detection of Aerosol Particles from Siberian Biomass Burning over the Western North Pacific

Autor: Momoka Yoshizue, Fumikazu Taketani, Kouji Adachi, Yoko Iwamoto, Yasunori Tohjima, Tatsuhiro Mori, Kazuhiko Miura

Publikováno v: Atmosphere, Vol 11, Iss 11, p 1175 (2020)

Carbonaceous aerosol particles emitted from biomass burning (BB) have a large impact on the global climate. In particular, tarball particles (TBs), which are spherical organic aerosol particles, account for a large proportion of aerosol particles fro
