Electroless Gold-Modified Diatoms as Surface-Enhanced Raman Scattering Supports
Porous biosilica from diatom frustules is well known for its peculiar optical and mechanical properties. In this work, gold-coated diatom frustules are used as low-cost, ready available, functional support for surface-enhanced Raman scattering. Due to the morphology of the nanostructured surface and the smoothness of gold deposition via an electroless process, an enhancement factor for the p-me...
متن کاملSurface Oxidation of Carbon Nanofibres
Carbon nanofibres of the fishbone and parallel type were surface-oxidised by several methods. The untreated and oxidised fibres were studied with infrared spectroscopy, thermogravimetric analysis and XPS. Oxidation in a mixture of concentrated nitric and sulfuric acid turned out to be the most effective method for creating oxygen-containing surface groups. This treatment results not only in the...
متن کاملDevelopment of Surface-Modified Polyacrylonitrile Fibers and Their Selective Sorption Behavior of Precious Metals
The purpose of this study was to design a powerful fibrous sorbent for recovering precious metals such as Pd(II) and Pt(IV), and moreover for identifying its selectivity toward Pd(II) or Pt(IV) from a binary metal solution. For the development of the sorbent, polyacrylonitrile (PAN) was selected as a model textile because its morphological property (i.e., thin fiber form) is suitable for fast a...
متن کاملDeformability of a Textile Reinforcement Modified with Nanofibres
Deformability of a textile fabric is studied experimentally using a) friction test, b) out-of-plane compression, and c) bending. These tests reveal that a grafting of the fabric with carbon nano-fibres can significantly deteriorate its deformability. Therefore an optimal CNF mass fraction should be chosen for a particular production case, to obtain a compromise between improved strength and dec...
متن کاملevaluation of surface roughness of polyacrylonitrile nanowebs
the objective of this research work is to evaluate the surface roughness of polyacrylonitrile (pan) nanowebs. for this purpose the nanowebs have been prepared in different concentrations of pan solution from 11 to 15% (by wt). surface roughness of nanowebs was evaluated by entropy algorithm (ent) as well as atomic force microscopy (afm) and then the results of two methods have been compared. to...
