Mass Spectrometric Identification of Au68(SR)34 Molecular Gold Nanoclusters with 34-Electron Shell Closing

Mass Spectrometric Identification of Au68(SR)34 Molecular Gold Nanoclusters with 34-Electron Shell Closing

Introduction

One of the important and interesting problems of modernization of catalysis is to study the causes of the catalytic-matic activity of nano-clusters of noble metals such as silver and gold on the surfaces oxides, in particular for catalytic reactions oxidation. Many researchers have made the mass spectrometric identification of Gold to determine its Gold Nanoclusters. This research paper presents an analysis of article Mass Spectrometric Identification of Au 68(SR) 34 Molecular Gold Nanoclusters with 34-Electron Shell Closing article written by Amala Dass.

Gold Nano-Clusters with 34-Electron Shell - Descriptive Analysis

Gold nano-clusters with 34-Electron closing shell exhibit remarkable properties, updates optics, catalysis, in the molecular chemical field. It also brought the answers to the challenges of miniaturization in electronics. Mass Spectrometric Identification shows that depositing nano-particles remote tunnel (1 nm) of a substrate, using a self-organized molecular layer of gold. This facilitates the identification of molecular nano-clusters such as Au25(SR)18, Au38(SR)24, and Au144(SR)59.

Molecular spectrum technology is becoming a key component of element structural analysis domain. Mass spectrometric identification presents an array of achievements that reach the general public, such as so-called AMOLED screens that have a growing number of mobile organic light emitting diodes (OLED), organic transistors (OFETs), etc. In order to incorporate molecular gold nano-clusters with 34-electron shell to current technology, it is essential must come to organize well-chosen organic molecules on gold surfaces, the substrate of choice for electronics. 

Gold nano-clusters are produced and incorporated into products and processes; they will inevitably enter the environment and come in contact with active chemical compounds. The novel properties of materials with at least one dimension smaller than 100 nanometers can cause it to behave differently from their bulk counterparts (Stevenson, 2008). These special characteristics and interactions are the reason that Gold nano-clusters with 34-Electron shell are advantageous for new or improved applications, as well as why they may interact with organisms and the environment in unexpected ways (Dass, 2009).

Some of these unpredictable impacts will be positive, and some will be potentially harmful. Regulators, companies, researchers, and the public agree that methods for assessing the relative safety of nonmaterial are needed immediately. The potential for negative impacts must be addressed if we are to realize the positive gains of Molecular Gold Nanoclusters with 34-Electron Shell. To this end, Mass Spectrometric ...
