Structural order in ultrathin films of the monolayer protected clusters based upon 4 nm gold nanocrystals: an experimental and theoretical studyStructural order in ultrathin films of the monolayer protected clusters based upon 4 nm gold nanocrystals: an experimental and theoretical study
(Royal Society of Chemistry, 2014-05)
The structural order in ultrathin films of monolayer protected clusters (MPCs) is important in a number of application areas but can be difficult to demonstrate by conventional methods, particularly when the metallic core ...
Chemiresistor Arrays Prepared by Simple and Fast Vapor-Phase Thiol Place-Exchange Functionalization of Gold Monolayer-Protected Cluster Films
(Wiley-VCH, 2016-08)
We describe a simple, versatile, and relatively fast method to alter the sensor selectivity of chemiresistors based on films of Au monolayer-protected clusters (MPCs) by varying their functionalization via vapor-phase thiol ...
Are 4-Mercaptobenzoic Acid self assembled monolayers on Au(111) a suitable system to test adatom models?
(American Chemical Society, 2012-12-04)
The adsorption of 4-mercaptobenzoic acid (MBA) has been studied on Au(111) by scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS), electrochemical techniques, and density functional theory (DFT) ...
New Findings for the Composition and Structure of Ni Nanoparticles Protected with Organomercaptan Molecules
(American Chemical Society, 2013-03-21)
Here we explore the synthesis of alkanethiolcoated Ni NPs following the one-phase reaction method by Brust et al.1 The reduction of NiCl2 with NaBH4 in the presence of dodecanethiol (C12SH) yields a complex product ...
Chemiresistive sensing with chemically modified metal and alloy nanoparticles
(Wiley, 2012-01)
This review describes the use of chemically-modified pure and alloy metal nanoparticles for chemiresistive sensing applications. Chemiresistors are materials that change their resistance in the presence of a particular ...

Bonding in Superatoms and Molecules made from. Analogs to Atoms and Simple Molecules and Related Concepts
(2017)
Recently, it has been shown that the superatom concept is intimately connected to
relevant tools of great chemical significance, such as the Lewis structure model and
the VSEPR theory, which has been employed to understand ...
Liquid-liquid microextraction based on a dispersion of Pd nanoparticles combined with ETAAS for sensitive Hg determination in water samples
(Elsevier Science, 2013-03-07)
A novel and highly efficient microextraction methodology based on the use of palladium nanoparticles (Pd NPs) was developed for the preconcentration and determination of Hg in water samples. Selective separation of the ...
