Wavelength dependence of polyyne preparation by liquid-phase laser ablation using pellet targets

The amount of polyynes produced by Nd:YAG laser (355, 532, and 1064 nm) ablation of fullerene and graphite pellet targets was the largest for 1064 nm ablation, contrary to the powder target in the previous report. This result is believed to come from the difference in the main polyyne-production area in liquids in the optical cell, depending on the pellet and powder targets.     

Estimation of the lead–lag parameter between two stochastic processes driven by fractional Brownian motions

Statistical Inference for Stochastic Processes - In this paper, we consider the problem of estimating the lead–lag parameter between two stochastic processes driven by fractional Brownian...     

Nanosized gold clusters formation in selected areas of soda-lime silicate glass

Nanosized gold clusters were developed in a gold-doped soda-lime silicate glass after X-ray irradiation followed by annealing, which provided an alternative way of forming metallic nanoclusters in glass to ion implantation. The formation of gold nanoclusters can be controlled by irradiation time or annealing time.     

Fluorinated polysilanes. palladium-catalyzed disilane metathesis,double silylation of acetylenes,and the stereo chemical course

Fluorinated and angle-strained Si—Si compounds undergo palladium-catalyzed disilane metathesis and double silylation of acetylenes, the latter being stereospecific at silicon atoms.     

Silafunctional compounds in organic synthesis. 28. Conjugate addition of a hydroxymethyl anion synthon to α,β-enones

The title reaction has been achieved by a sequence of the copper-catalyzed conjugate addition of the (allyldimethylsilyl)methyl Grignard reagent, fluorodeallylation and the H₂O₂-oxidation of the carbon-silicon bond therein.
