Lim HH, Kurimura S, Noguchi K, Shoji I.
PMID: 25089446
Opt Express. 2014 Jul 28;22(15):18268-77. doi: 10.1364/OE.22.018268.

We analyze a solution of the heat equation for second harmonic generation (SHG) with a focused Gaussian beam and simulate the temperature rise in SHG materials as a function of the second harmonic power and the focusing conditions. We...

Borinium cations (R2B(+)) are of particular fundamental and applied interest in part due to their pronounced Lewis acidity which enables unique chemical transformations. Solid-state NMR spectroscopy of magic-angle spinning and stationary powdered samples of the dicoordinate boron cation in...

Recent findings that glial cell line-derived neurotrophic factor (GDNF), neurotrophin-3 (NT-3), and transforming growth factor a can protect the auditory hair cells from acoustic trauma or aminoglycoside ototoxicity in vivo raise the question of whether other neurotrophic factors can...

Magnetic Circular Dichroism (MCD) of Resonant Inelastic X-ray Scattering (RIXS) of 3d(5/2) --> 2p(3/2) decay (Ho Lalpha1) was measured at the Ho L(III)-edge in Ho3Fe5O12. The MCD-RIXS, in which the intermediate state has the 2p4f(n+1) configuration due to the...

Optical measurements of paired luminous rings in capacitive radio-frequency hydrogen discharges.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 1999 Nov;60(5):6007-15. doi: 10.1103/physreve.60.6007.

Optical measurements of paired luminous rings separated by a narrow dark gap have been conducted in capacitive radio-frequency (rf) hydrogen discharges. The lines of molecular H(2) are strongly excited at the ring emission compared with a weaker emission of...

Small-Angle X-Ray Scattering Studies on Nucleation Formation of Dextran Precipitation in the Presence of Boron.

Journal of colloid and interface science

PMID: 10684677
J Colloid Interface Sci. 2000 Mar 01;223(1):139-141. doi: 10.1006/jcis.1999.6656.

In the present study, the nucleation formation process of dextran precipitation in the presence of boron was investigated by small-angle X-ray scattering (SAXS) techniques. The formation mechanism of aggregates or nuclei is very important in the initial step of...

Rh-catalyzed [4 + 2] carbocyclization of vinylarylaldehydes with alkenes and alkynes leading to substituted tetralones and 1-naphthols.

Organic letters

Org Lett. 2007 May 24;9(11):2059-62. doi: 10.1021/ol0704587. Epub 2007 Apr 26.

Regio-, diastereo-, and enantioselective intermolecular [4 + 2] carbocyclizations of vinylarylaldehydes with alkenes and alkynes leading to substituted tetralones and 1-naphthols have been developed by using a cationic rhodium(I)/dppb or dppp complex as a catalyst.

Formation and self-breaking mechanism of stable atom-sized junctions.

Nano letters

Tsutsui M, Shoji K, Taniguchi M, Kawai T.
PMID: 18095741
Nano Lett. 2008 Jan;8(1):345-9. doi: 10.1021/nl073003j. Epub 2007 Dec 21.

The self-breaking mechanism of gold junctions is studied by investigating stability of the atom-sized contacts. The single atom contact lifetime increases from about 0.02 to 200 s upon decreasing the junction stretching speed, while at the same time, the...

Synthesis of isolable thiirane-2-thione (alpha-dithiolactone) from thioketene S-oxide.

Reaction of di-tert-butyl thioketene S-oxide with Lawesson reagent gave 3,3-di-tert-butylthiirane-2-thione in 88% yield. Oxidation of thiirane-2-thione with m-chloroperbenzoic acid afforded 3,3-di-tert-butylthiirane-2-thione S-oxide. The reaction of thiirane-thione was described.

PMID: 16946795
Appl Opt. 2006 Sep 20;45(27):7144-50. doi: 10.1364/ao.45.007144.

A wideband design is proposed for nonreciprocal phase shift magneto-optical isolators based on Mach-Zehnder interferometers. The wavelength dependence of nonreciprocal phase difference between the backward waves propagating in two interferometer arms is compensated for by that of reciprocal phase...
