A simple and efficient numerical model describing the processes of nucleation, growth and transport of multi-component nanoparticles is developed. The approach is conceptually similar to the classical method of moments but can be applied to co-condensation of several substances. The processes of homogeneous nucleation, heterogeneous growth, and coagulations due to Brownian collisions are consid...

Optical Emission Spectroscopy and Rutherford Backscattering Spectrometry are combined to determine condensation coefficients for plasma sputtering deposition. The method is applied for palladium deposition onto various substrates and condensation coefficients are found to lie between 0.4 and 0.9. PACS numbers: 81.15.Cd, 52.77.Dq Submitted to: J. Phys. D: Appl. Phys. § Corresponding author: Fax ...

Synthetic methods to obtain selectively sulfonated metallo phthalocyanines are compared. Both condensation and direct sulfonation procedures lead to mixtures of monoto tetrasulfonated products which are resolved by reverse phase liquid chromatography in buffered aqueous-methanol. The proportion of sulfonated derivatives is examined as a function of the starting reagents in the case of the conde...

The assembly of melamine and 2,5-dihydroxy-1,4-benzoquinone results in new "sheet-like" supramolecular crystals that by controlled thermal condensation can be converted to photoactive materials at relativity low temperatures. The condensation temperature alters the materials properties from polymer-like to carbon materials alongside their morphology and elemental ratio. This new method opens th...

The strongly correlated regime of the crossover from Bardeen-Cooper-Schrieffer pairing to Bose-Einstein condensation can be realized by diluting a system of two-component fermions with a short-range attractive interaction. We investigate this system via a novel continuous-space-time diagrammatic determinant Monte Carlo method and determine the universal curve Tc/epsilonF for the transition temp...

a series of n-substituted-2,4-thiazolidinedione derivatives (tzds) were prepared via n-alkylation of 2,4-tzd at position 3 using substituted benzyl halides. synthesized n-substituted-2,4-tzd was then substituted at position 5 with substituted aromatic aldehyde according to knoevenagel condensation method. structures of the compounds were elucidated using various spectral techniques viz. ir, 1hn...

In this paper, we propose an efficient method for tracking multiple objects, which deals with occlusion situations in an image. We use Shape from silhouettes method to reconstruct objects 3D position from images taken from different directions. Then we track the objects' reconstructed 3D positions by using mixed-state CONDENSATION algorithm. The experimental results show the robust tracking of ...

A rapid, clean, and highly efficient method for synthesis of dihydropyrano[3,2-c]chromene derivatives by one-pot, three-component condensation of aromatic aldehydes, malononitrile, and 4-hydroxycoumarin using DABCO as catalyst in solvent-free neat conditions is described. The present method has the advantages of mild reaction conditions, short reaction times, easy isolation of products, and exc...
