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 ...
Protein capped nanosilver free radical oxidation: role of biomolecule capping on nanoparticle colloidal stability and protein oxidation
(ROYAL SOC CHEMISTRY, 2018)
We studied the effect of human serum albumin protein capped spherical nanosilver on the nanoparticle stability upon peroxyl radical oxidation. The nanoparticle-protein composite is less prone to oxidation compared to the ...
Layer-by-layer assembled gold nanoparticles/lower-generation (Gn <= 3) polyamidoamine dendrimers-grafted reduced graphene oxide nanohybrids with 3D fractal architecture for fast, ultra-trace, and label-free electrochemical gene nanobiosensors
(ELSEVIER ADVANCED TECHNOLOGY, 2018)
Three layer-by-layer (LBL) assembled gold nanoparticles (AuNPs)/lower-generation (Gn <= 3) polyamidoamine dendrimer (PD) with reduced graphene oxide (rGO) as the core/mercaptopropinoic acid (MPA)/Au were successfully ...
A mechanistic approach for the optimization of loperamide loaded nanocarriers characterization: Diafiltration and mathematical modeling advantages
(ELSEVIER SCIENCE BV, 2018)
Oral bioavailability of loperamide is restricted by its limited absorption in the gastrointestinal tract due to its poor aqueous solubility and its P-glycoprotein (Pgp) substrate characteristic. In addition, ammonium ...
NANoPoLC algorithm for correcting nanoparticle concentration by sample polydispersity
(ROYAL SOC CHEMISTRY, 2018)
Variability in the polydispersity of colloidal nanoparticles results in significant differences in the total number of nanoparticles available for the determination of their concentration, which ultimately affects their ...
Regulation of developing myelin sheath elongation by oligodendrocyte calcium transients in vivo
(NATURE PUBLISHING GROUP, 2018)
How action potentials regulate myelination by oligodendrocytes is uncertain. We show that neuronal activity raises [Ca2+](i) in developing oligodendrocytes in vivo and that myelin sheath elongation is promoted by a high ...
Association between FTO (ns9939609) genotype and adiposity markers in Chilean adults [Asociación entre el polimorfismo rs9939609 del gen FTO y marcadores de adiposidad en población adulta chilena]
(Sociedad Médica de Santiago, 2018)
Background: Numerous studies have identified the role of Fat-mass-associated-gene (FTO) in the development of obesity. Aim: To investigate the association of FTO gene with adiposity markers in Chilean adults. Material and ...
