In this work the applicability of neopentasilane (Si(SiH(3))(4)) as a precursor for the formation of silicon nanowires by using gold nanoparticles as a catalyst has been explored. The growth proceeds via the formation of liquid gold/silicon alloy droplets, which excrete the silicon nanowires upon continued decomposition of the precursor. This mechanism determines the diameter of the Si nanowire...

We compared the structural and optical properties of gold films deposited on copper substrates by traditional fire-gilding method electroplating which are being adopted craftsmen in Kathmandu valley, Nepal. Atomic force microscopy (AFM) reflectance spectroscopy were employed to characterize surface morphology samples, respectively. In AFM images films, we observed that surfaces fire-gilded not ...

The goal of this article is to offer a series results related the existence and properties wavefront solutions for doubly nonlinear diffusion–reaction equations involving p-Laplacian operator in terms constitutive functions problem. These are derived from analysis singular Volterra integral that appear study monotone travelling-wave such equations. Our extend ones due B. Gilding R. Kersner case...

are independent of x ∈ R . One of the main results of [5] is the following. Theorem A. Assume 0 < q < 2 and u0 ∈ Cb(R ). Then ω = ω. It was known that Theorem A fails for the linear heat equation and, moreover, Gilding observed that it fails for q = 2. The aim of this short note is to show that the assumption q < 2 in Theorem A is actually necessary. Theorem 1. Assume q ≥ 2. Then there exists u...

Abstract This paper outlines the use of bidirectional reflectance measurements for characterisation and evaluation appearance changes in gilded surfaces caused by varnishing cleaning. Oil water gilding mock-ups representative a 15th-century panel painting were varnished, selection four varnish removal methods was applied. By measuring samples, their modelled evaluated according to perceptual gl...
