Magnetically recoverable nano-catalysts in sulfoxidation reactions

open access: yesNanotechnology Reviews, 2017
The sulfoxidation of sulfides have received special attention in organic synthesis especially in medical chemistry because compounds containing S=O bonds (sulfoxides) are privileged structural scaffolds for building pharmacologically and biologically ...

Metal-organic frameworks as selective or chiral oxidation catalysts [PDF]

open access: yes, 2014
Since the discovery of Metal Organic Frameworks (MOFs) in the early 1990s, the amount of new structures has grown exponentially. A MOF typically consists of inorganic nodes that are connected by organic linkers to form crystalline, highly porous ...

The Electrochemical Oxidation of Organic Selenides and Selenoxides [PDF]

open access: yes, 1997
The electrochemical oxidation of alkyl and aryl selenides was investigated in acetonitrile. The oxidation of diphenyl selenide and di(4‐methylphenyl) selenide led primarily to the formation of their respective selenoxides, which were identified by ...

Are collapse models testable with quantum oscillating systems? The case of neutrinos, kaons, chiral molecules

open access: yes, 2013
Collapse models provide a theoretical framework for understanding how classical world emerges from quantum mechanics. Their dynamics preserves (practically) quantum linearity for microscopic systems, while it becomes strongly nonlinear when moving ...

Microcellular Poly (Ethylene‐Co‐Vinyl Acetate)/Lignin Nanocomposites for Soft Ferroelectrets

open access: yesAdvanced Engineering Materials, EarlyView.
Lignin valorization for advanced porous polymer nanocomposites development and an upscaling route for continuous manufacturing of soft ferroelectrets for energy harvesting are studied. This work examines the role of lignin and carbon nanotubes (CNT) in modifying the mechanical, dielectric, and ferroelectret properties of poly (ethylene‐co‐vinyl acetate)

Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

open access: yesAdvanced Engineering Materials, EarlyView.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

Biomimetic sulfide oxidation by the means of immobilized Fe(III)-5,10,15,20-tetrakis(pentafluorophenyl)porphin under mild experimental conditions [PDF]

open access: yes, 2013
This paper describes the oxidation of inorganic sulfide to sulfate, minimizing the formation of elemental sulfur. The described catalytic reaction uses dilute hydrogen peroxide at nearly neutral pH values in the presence of a bioinspired, heterogenized ...
