The effects of nanoparticles on mouse testis Leydig cells in vitro.
We have indicated the possibility that nanoparticles such as diesel exhaust particles (DEP) and titanium dioxide (TiO(2)) may impair the male mouse reproductive system. In this study, to evaluate theExpand

High spatial resolution 3D analysis of materials using gallium focused ion beam secondary ion mass spectrometry (FIB SIMS)
Abstract The sharpness and high density of focused ion beams (FIB) enable micromachining of materials. When a gallium FIB is used as a primary beam for secondary ion mass spectrometry (SIMS), 2DExpand

A Novel Glucose Sensor with a Glucose Oxidase Monolayer Immobilized by the Langmuir–Blodgett Technique
A monomolecular layer of glucose oxidase (GOD) was immobilized on an SnO2 electrode via glutaraldehyde-bridged covalent bonding of GOD to the amino moieties of an octadecylamine Langmuir–BlodgettExpand

Characterization of individual complex particles in urban atmospheric environment
Abstract The origins of carrier particles of complex particles (iron-rich particles) collected from the urban atmospheric environment near to road traffic and a railroad were investigated from theExpand

Interaction between diesel exhaust particles and cellular oxidative stress
Abstract The cellular oxidative stress by the exposure of diesel exhaust particles (DEPs) was investigated by using a time of flight secondary ion mass spectrometry (TOF-SIMS) and a real time reverseExpand

Individual particle analysis for source apportionment of suspended particulate matter using electron probe microanalysis
Suspended particulate matter (SPM) has a complicated system of emission and transport, and a receptor model is required for apportioning the sources of SPM. We have developed a method for individualExpand

Specific heat and metal-insulator transition of (BEDT-TTF)2MZn(SCN)4(M=Cs,Rb)
We have studied thermal properties of (BEDT- TTF)2MZn (SCN)4(M=Cs, Rb) with special interest in the metal-insulator transition, which is drastically modified by the cooling condition, and mysteriousExpand
