Journal ArticleDOI
Pattern formation and flow control of fine particles by laser-scanning micromanipulation
TL;DR: A novel micromanipulation technique is proposed for aligning fine particles on micrometer-scale spatial patterns and for moving the particles continuously along the formed patterns.
Journal ArticleDOI
Charge Carrier Dynamics of Standard TiO2 Catalysts Revealed by Femtosecond Diffuse Reflectance Spectroscopy
TL;DR: In this article, the dynamics of charge carriers generated by femtosecond UV (160 fs, 390 nm) excitation in five standard TiO2 photocatalytic powders (JRC-TIO-1, -2, -3, -4, and -5 supplied by the Catalysis Society of Japan) in a vacuum and air was investigated by means of time-resolved femto-cond diffuse reflectance spectroscopy, and discussed from the viewpoints of crystal structure (anatase and rutile), particle size, and surrounding condition around the
Journal ArticleDOI
Optical trapping of a metal particle and a water droplet by a scanning laser beam
TL;DR: In this paper, a scanning laser beam was used to trap a metal particle in water or a water droplet in liquid paraffin, which cannot be achieved by irradiation of a TEM00 mode focused laser beam.
Journal ArticleDOI

TL;DR: In this article, two new anil molecules exhibiting photochromism in the crystalline state, N-(4-hydroxy)-salicylidene-amino-4-(methylbenzoate) (2) and N-(3,5-di-tert-butylsaliclyidene)-4-aminopyridine (3), are obtained.
Journal ArticleDOI
Laser Fabrication and Spectroscopy of Organic Nanoparticles
TL;DR: This Account describes recent advances in laser technology both for the synthesis of organic nanoparticles and for their analysis by single nanoparticle spectroscopy and proposes "structural confinement" as an analogous paradigm fororganic nanoparticles.
