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 ...
Electrochemical in situ synthesis of polypyrrole nanowires
(ELSEVIER SCIENCE INC, 2019)
Modification with polypyrrole nanowires, PPy-nw, is accomplished directly upon the working electrode by electrochemical polymerization methods using mesoporous silica as a template. The silica template is prepared by a ...
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 ...
Size and temperature dependent magnetization of iron nanoclusters
(Chile. Universidad Mayor, 2020)
The magnetic behavior of bcc iron nanoclusters, with diameters between 2 and 8 nm, is investigated by means of spin dynamics simulations coupled to molecular dynamics, using a distance-dependent exchange interaction. ...
Utilization of industrial by-product fungal biomass from Aspergillus niger and Fusarium culmorum to obtain biosorbents for removal of pesticide and metal ions from aqueous solutions
(Chile. Universidad Mayor, 2020)
In this work, Aspergillus niger and Fusarium culmorum cell wall by-products were chosen as microbial sources for chitin and chitosan production. Both polysaccharides were characterized by FTIR and C-13-CPMAS NMR, but GPC ...
Rational Design, Synthesis and Evaluation of CD-Containing as a Prednisone Delivery Platform
(Facultad de Ciencias, 2018)
This study describes the in-silico rational design, synthesis and evaluation of cross-linked polyvinyl alcohol hydrogels containing γ-cyclodextrin (γ-CDHSAs) as platforms for the sustained release of prednisone (PDN). ...
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 ...
Inducing Porosity on Hollow Nanoparticles by Hypervelocity Impacts
(American Chemical Society, 2017)
The large surface-to-volume ratio of hollow palladium nanoparticles (hNPs) offers room to improve their hydrogen storage capacity as well as their catalytic activity. However, a less explored possibility is to use, in ...
