Synthesis of microporous/mesoporous core-shell materials with crystalline zeolitic shell and supported metal oxide silica core
(Royal Society of Chemistry, 2016-04)
An engineered material, possessing a hierarchical porosity in a shape selective manner, was synthesized by placing a microporous silicalite-1 shell over silica microspheres embedded with various guest species. Core materials ...
Structured Magnetic Core/Silica Internal Shell Layer and Protein Out Layer Shell (BSA@SiO2@SME): Preparation and Characterization
(2020-03-01)
Purpose: Magnetic nanoparticles are an interesting approach in the biomedical and biotechnological field. They can be used as a drug delivery system or in magnetic resonance imaging. However, these particles have the ...
Ostracode biofacies and shell chemistry reveal quaternary aquatic transitions in the Pozuelos basin (Argentina)
(Society for Sedimentary Geology, 2017-06-01)
Here we present the first use of calcareous microfossils to examine the late Quaternary paleoecology of the endorheic Pozuelos Basin (Argentina). Modern deposition in the basin centers on Laguna de los Pozuelos (LP),a shallow ...
Controlling the dominant magnetic relaxation mechanisms for magnetic hyperthermia in bimagnetic core-shell nanoparticles
(Royal Society of Chemistry, 2019-02)
We report a simple and effective way to control the heat generation of a magnetic colloid under alternate magnetic fields by changing the shell composition of bimagnetic core–shell Fe3O4/ZnxCo1−xFe2O4 nanoparticles. The ...
Theory of d 10 - d 10 Closed-Shell Attraction. III. Rings
(1998)
We study the dependence of the intramolecular M I-M I interaction on electron correlation effects in eight-membered rings of type [M 2(PH 2CH 2PH 2) 2] 2+, [M 2(NHCHNH) 2], [M 2(SCHS) 2] (M = Au, Ag, Cu), [Au 2(PH 2CH 2PH ...
Surface And Interface Interplay On The Oxidizing Temperature Of Iron Oxide And Au-iron Oxide Core-shell Nanoparticles
(Royal Society of Chemistry, 2016)
Topology of the electron density in open-shell systems
(American Chemical Society, 2010-01)
This work describes the decomposition of the electron density field of open-shell molecular systems into physically meaningful contributions. The new features that the open-shell nature of the wave function introduces into ...
Shell-mediated control of surface chemistry of highly stoichiometric magnetite nanoparticles
(Royal Society of Chemistry, 2020-07)
Magnetite (Fe3O4) nanoparticles are one of the most studied nanomaterials for different nanotechnological and biomedical applications. However, Fe3O4 nanomaterials gradually oxidize to maghemite (γ-Fe2O3) under conventional ...
A shell model for cross relaxation in elpasolite crystals: application to the 3P0 and 1G4 states of Cs2NaY1-xPrxCl6
(1995)
A model for cross relaxation in high symmetry systems is developed. The positions of all acceptor ions and all multipole-multipole interactions may be included. The geometric factors are explicitly considered. A feature ...
