Optical Simulation for Multi-Striped Orthogonal Photon-Photocarrier-Propagation Solar Cell (MOP³SC) with Redirection Waveguide

We have calculated optical fields for waveguide-coupled orthogonal photon-photocarrier propagation solar cell (MOP³SC)in which the photons propagate in the direction orthogonal to that of the photocarriers’. By e...

Molecular orientation effects in gas-surface dynamical processes

We report studies of chemical reactions on single crystalline Si surfaces induced by oriented molecular beams. We discuss the obtained steric effects on Si from the viewpoint of the strength of the gas-surface...

The electronic structure and magnetic property of μ-hydroxo bridged manganese porphyrin dimer

The electronic structure and effective exchange integrals (J _ab) between two manganese (III) ions of porphyrin dimer (PPMn(III)–OH–Mn(III)PP) were examined by using unrestricted hybrid DFT (UHDFT) methods. The ...

State-selection and orientation of CH radicals by an electric hexapole

A pure and high intense pulsed supersonic CH (X²Π ) radical beam source was developed via the C(¹D) + H₂ reaction. An electrostatic hexapole field was used to state-select CH radicals. The focusing curves for ...

M_J and collision energy dependent attenuation of Rg (³P₂) by CF₃Br

The total attenuation cross-section of Rg (³P₂) (Rg = Ar, Kr) by the collision with CF₃Br is measured as a function of the magnetic sub level M_J of Rg (³P₂) and the collision energy. For Ar (³P₂), the attenuat...

The azimuthal dependent oxidation process on Cu(110) by energetic oxygen molecules

We report a study on the oxidation process induced by a hyperthermal oxygen molecular beam (HOMB) on Cu(110) using X-ray photoemission spectroscopy in conjunction with a synchrotron radiation source. The o...

Characterization of an oriented metastable atom source based on a magnetic hexapole

The M_J-state selection of the metastable rare-gas (Rg*) was achieved by a magnetic hexapole that is composed of permanent magnets. The performance of the magnetic hexapole was examined by characterizing the velo...

The N-terminus of rodent and human MAD1 confers species-specific stringency to spindle assembly checkpoint

The spindle assembly checkpoint (SAC) guards against chromosomal mis-segregation and the emergence of aneuploidy. SAC in higher eukaryotes includes at least 10 proteins including MAD1-3, BUB1-3, and Msp1. A lo...

Multiwalled carbon nanotube AFM probes for surface characterization of micro/nanostructures

A multiwalled carbon nanotube (MWNT) probe was used as a scanning probe in an atomic force microscope (AFM) to obtain surface height maps of micro/nano structures. The surface height maps acquired by the MWNT ...

Local drug delivery system using ceramics: vacuum method for impregnating a chemotherapeutic agent into a porous hydroxyapatite block

We performed an experimental study on a new drug delivery system that employs a porous hydroxyapatite block (HAb) (composition: Ca₁₀ (PO₄)₆ (OH)₂) to conduct sustained release of a chemotherapeutic agent. To conf...
