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 ...
Physical-chemical properties of M@Fe3O4 core@shell nanowires (M = Cu, Co, CoO)
(ROYAL SOC CHEMISTRY, 2019)
Interest in low dimensional magnetic systems has been growing due to the novel and dramatically differentiated effects of their physical properties, which give them special behaviors and uses in biomedical, environmental ...
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 ...
Using classical Cepheids to study the far side of the Milky Way disk: I. Spectroscopic classification and the metallicity gradient
(Chile. Universidad Mayor, 2020)
Context. Much of what we know about the Milky Way disk is based on studies of the solar vicinity. The structure, kinematics, and chemical composition of the far side of the Galactic disk, beyond the bulge, are still to be ...
Tri-functional oligomeric polyesters prepared from new dicarboxylic acids containing several amino acids residues by Higashi methodology: synthesis, characterization, and study of solubility and thermal behavior
(Chile. Universidad Mayor, 2021)
The synthesis of polyfunctional aliphatic oligomeric polyesters (poly(ether-imido-esters;PEIEs) containing several amino acid residues is described, and their thermal properties and solubility behavior were studied. The ...
Ethylene polymerization by binuclear chromium complex with tetrakis(pyrazolyl-methyl)benzene ligand
(Chile. Universidad Mayor, 2020)
The reaction of one equivalent of 1,2,4,5-tetrakis(pyrazolyl-methyl)benzene ligand (L) with two equivalents of Cr(THF)(3)Cl-3 in tetrahydrofuran has produced a binuclear neutral complex of general formula [Cr2L(THF)(2)Cl-6] ...
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), ...
