In Situ Observation of Oscillatory Growth of Bismuth Nanoparticles

Nano Letters, 2012
We study the growth of Bi nanoparticles in an engineered precursor-scarce environment in a liquid cell at an elevated temperature (180 °C) using transmission electron microscopy. Observation reveals dynamics of oscillatory growth of individual nanoparticles, pairwise Ostwald ripening and anti-Ostwald ripening and a global collective oscillation.

In situ approaches to establish colloidal growth kinetics

Journal of Colloid and Interface Science, 2004
A technique based on the back scattering phenomenon of dynamic light scattering has been employed to monitor the kinetics of gold and platinum metal nanoparticle growth and silver nanoparticle oxidation as well as in the determination of particle sizes ranging from 1 to 200 nm in diameter. The systems were chosen to examine the applicability of dynamic

In-situ Ellipsometry and in-situ Raman thin film growth monitoring

Optical Interference Coatings, 2004
Fast and reliable optical in-situ process diagnostics by spectroscopic ellipsometry and Raman scattering spectroscopy demonstrated. Applications: design and control of dielectric multilayer mirros for soft-x-ray applications and solar-cell absorber layers deposited within a roll-to-roll system.

In SituStudy of the Growth of Nanodots in Organic Heteroepitaxy

Physical Review Letters, 2006
We report the self-organization of organic nanodots with high crystallinity during the growth of organic heterostructures of Di-indenoperylene (DIP) onto copper-hexadecafluorophthalocyanine (F16CuPc), donor and acceptor molecules, respectively. The process is related to the Stranski-Krastanov growth mode, which is accompanied by a novel type of ...

In Situ and Ex Situ Observations of the Growth Dynamics of Single Perylene Nanocrystals in Water

Journal of the American Chemical Society, 2006
The growth dynamics of fluorescent perylene nanocrystals, which are fabricated by the reprecipitation method, was investigated using in situ and ex situ single-particle fluorescence measurements. A red shift in the emission maxima as the aging time increased was observed by single-particle fluorescence spectral measurements.

Growth Hormone Deficiency, Situs Inversus, Hypertrichosis and Brachydactyly

Journal of Pediatric Endocrinology and Metabolism, 2003
A 6 year-old female showed growth hormone deficiency, situs inversus totalis, short stature, blue sclerae, facial dismorphism, brachydactyly, developmental delay and hypertrichosis. The described phenotype represents a new syndromic situs inversus with a characteristic phenotype.

In-situ synthesis and growth of indium phosphide

Journal of Electronic Materials, 1983
The high partial pressure of phosphorus at the stoichiometric melting point of InP precludes the in-situ synthesis in the puller by simple admixture of indium and phosphorus. This paper describes a system that was considered for the in-situ synthesis and growth of InP single crystal, utilizing the phosphorus vapor injection method.

A Technique for In—Situ Detection of Growth Dislocations

MRS Proceedings, 1985
ABSTRACTA formidable obstacle to develop the optimal conditions for growing dislocation—free crystals has been the lack of a direct technique to monitor the perfection of the solid/liquid (S/L) interface during growth. Recently we have developed a technique which detects, in—situ, the emergence of dislocation(s) at the crystallization front. This novel

In-situ observation of crystal growth and the mechanism

Progress in Crystal Growth and Characterization of Materials, 2016
Abstract The spatial and time resolution in the measurements of growth rates and the observation of surface morphologies and the associated transport phenomena reflecting their growth mechanism have been developed because advanced microscopes and interferometers have attained nano-scale resolution.
