Scientific reports

Ueno T, Saito K, Yano M, Ito M, Shoji T, Sakuma N, Kato A, Manabe A, Hashimoto A, Gilbert EP, Keiderling U, Ono K.
PMID: 27321149
Sci Rep. 2016 Jun 20;6:28167. doi: 10.1038/srep28167.

We have investigated the influence of multiple scattering on the magnetic small-angle neutron scattering (SANS) from a Nd-Fe-B nanocrystalline magnet. We performed sample-thickness- and neutron-wavelength-dependent SANS measurements, and observed the scattering vector dependence of the multiple magnetic scattering. It...

Phys Chem Chem Phys. 2017 Mar 29;19(13):8941-8961. doi: 10.1039/c6cp08856b.

Sum frequency generation (SFG) spectroscopy is widely used to observe molecular orientation at interfaces through a combination of various types of polarization. The present work thoroughly examines the relation between the polarization dependence of SFG signals and the molecular...

Efficient terahertz detection in a sheet cavity using a nonlinear optical parametric process.

Applied optics

PMID: 26192850
Appl Opt. 2015 Jun 10;54(17):5475-80. doi: 10.1364/AO.54.005475.

We designed and simulated a GaP-based sheet cavity structure for room-temperature THz wave detection via a nonlinear optical (NLO) parametric process, using photonic conversion from THz frequencies to the optical domain. The sheet cavity structure consisted of a GaP...

Boosting Sensitivity in Liquid Chromatography-Fourier Transform Ion Cyclotron Resonance-Tandem Mass Spectrometry for Product Ion Analysis of Monoterpene Indole Alkaloids.

Frontiers in plant science

Front Plant Sci. 2015 Dec 17;6:1127. doi: 10.3389/fpls.2015.01127. eCollection 2015.

In metabolomics, the analysis of product ions in tandem mass spectrometry (MS/MS) is noteworthy to chemically assign structural information. However, the development of relevant analytical methods are less advanced. Here, we developed a method to boost sensitivity in liquid...

J Clin Aesthet Dermatol. 2015 Jun;8(6):36-44.

BACKGROUND: In the early 1990s, the biological significance of light-emitting diodes was realized. Since this discovery, various light sources have been investigated for their cutaneous effects.STUDY DESIGN: A Medline search was performed on light-emitting diode lights and their therapeutic...

Design of a GaP/Si composite waveguide for CW terahertz wave generation via difference frequency mixing.

Applied optics

PMID: 24921119
Appl Opt. 2014 Jun 10;53(17):3587-92. doi: 10.1364/AO.53.003587.

We design a GaP/Si composite waveguide to achieve efficient terahertz (THz) wave generation under collinear phase-matched difference frequency mixing (DFM) between near-infrared light sources. This waveguide structure provides a strong mode confinement of both near-infrared sources and THz wave,...

Tetra-cationic pyrene derivative (Py(4+)) and tris(bipyridine)ruthenium(II) (Ru(2+)) were hybridized onto the surface of a synthesized clay. We observed the remarkable stimulation of excited Py(4+) emission quenching on the clay surface, with a very large apparent quenching rate constant (kq...

γ-Silylboronates in the chiral Brønsted acid-catalysed allylboration of aldehydes.
