Tuning the structure and magnetic behavior of Ni-Ir-based nanoparticles in ionic liquids
(ROYAL SOC CHEMISTRY, 2018)
We report on a simple preparation of extremely small diameter (ca. 2 nm) Ni-Ir-based NPs using Ni(COD)(2) and [Ir(COD)OCH3](2) in 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (BMImNTf(2)). The prepared NPs ...
Toward Controlled Morphology of FeCu Nanoparticles: Cu Concentration and Size Effects
(AMER CHEMICAL SOC, 2018)
Bimetallic nanoparticles (NPs) can be tailored by varying the concentration of their constituent elements, resulting in novel structures and/or configurations, leading to interesting electronic, mechanical, and chemical ...
Simple voltammetric analyses of ochratoxin A in food samples using highly-stable and anti-fouling black phosphorene nanosensor
(PERGAMON-ELSEVIER SCIENCE LTD, 2018)
There are few reports on the electrochemical detection of ochratoxin A (OTA) using chemically modified electrode owing to the OTA poor electrochemical activity and strong fouling effect towards electrode surface. In this ...
Growth of Ni nanoclusters on irradiated graphene: a molecular dynamics study
(ROYAL SOC CHEMISTRY, 2018)
We studied the soft landing of Ni atoms on a previously damaged graphene sheet by means of molecular dynamics simulations. We found a monotonic decrease of the cluster frequency as a function of its size, but few big ...
Bending energy of 2D materials: graphene, MoS2 and imogolite
(ROYAL SOC CHEMISTRY, 2018)
The bending process of 2D materials, subject to an external force, is investigated, and applied to graphene, molybdenum disulphide (MoS2), and imogolite. For graphene we obtained 3.43 eV angstrom(2) per atom for the bending ...
Layer-by-Layer-Assembled AuNPs-Decorated First-Generation Poly(amidoamine) Dendrimer with Reduced Graphene Oxide Core as Highly Sensitive Biosensing Platform with Controllable 3D Nanoarchitecture for Rapid Voltammetric Analysis of Ultratrace DNA Hybridization
(AMER CHEMICAL SOC, 2018)
The structure and electrochemical properties of layer-by-layer-assembled gold nanoparticles (AuNPs)-decorated first-generation (G1) poly(amidoamine) dendrimer (PD) with reduced graphene oxide (rGO) core as a highly sensitive ...
Ion implantation in nanodiamonds: size effect and energy dependence
(NATURE PUBLISHING GROUP, 2018)
Nanoparticles are ubiquitous in nature and are increasingly important for technology. They are subject to bombardment by ionizing radiation in a diverse range of environments. In particular, nanodiamonds represent a variety ...
Catalytic effects of p-phenylene-bridged methylated binuclear ferrocenes on thermal decomposition of the main component of composite solid propellants
(ELSEVIER SCIENCE BV, 2018)
This contribution describes the catalytic activity of homobimetallic complexes derived from p-phenylene on the thermal decomposition of ammonium perchlorate (abbreviated as AP). The complexes, [CpFe-p-Ph-FeCp] (1), ...
Structural, electronic and catalytic properties of palladium nanoparticles supported on poly(ionic liquid)
(ELSEVIER SCIENCE BV, 2018)
The structural, electronic and support effect on palladium nanoparticles (Pd NPs) prepared by sputtering deposition and chemical reduction of a Pd(II) precursor in/on a poly(ionic liquid) (PIL) was investigated in the ...
Graphene Oxide Quantum Dots as the Support for the Synthesis of Gold Nanoparticles and Their Applications as New Catalysts for the Decomposition of Composite Solid Propellants
(AMER CHEMICAL SOC, 2018)
Graphene oxide quantum dot (GOQD) and reduced GOOD (rGOQD) were synthetized using a simple and straight methodology based on an oxidative treatment and sonication. GOQD and rGOQD were used as supporting agents for the in ...
