The synthesis and characterisation of some ortho-substituted phenoxyalkanoic acids and their derivatives [PDF]

open access: yesJournal of the Serbian Chemical Society, 2006
The synthesis of 2-phenoxyalkanoic acids (ethanoic, propanoic, butanoic) was realised by the reaction of ortho-hydroxybenzamide respectively N-phenyl-o-hydroxybenzamide with a-halogenated acids in aqueous sodium hydroxide solution.

Isaac Newton on the action at a distance in gravity: With or without God? [PDF]

open access: yes, 2019
The interpretation of Isaac Newton's texts has sparked controversy to this day. One of the most heated debates relates to the action between two bodies distant from each other (the gravitational attraction), and to what extent Newton involved God in this

On the road to unraveling the molecular functions of ether lipids

open access: yesFEBS Letters, 2019
Ether lipids are glycerolipids further classified into alkyl‐ether and alkenyl‐ether (also termed plasmalogens) lipids. The two ether lipid subclasses share the first steps of their synthesis. However, alkyl‐ether and alkenyl‐ether lipids differ in their

CO2 Recycling to Dimethyl Ether: State-of-the-Art and Perspectives

open access: yesMolecules, 2017
This review reports recent achievements in dimethyl ether (DME) synthesis via CO2 hydrogenation. This gas-phase process could be considered as a promising alternative for carbon dioxide recycling toward a (bio)fuel as DME. In this view, the production of

Tailoring the Properties of Functional Materials With N‐Oxides

open access: yesAdvanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

Multi‐Faceted Binder Enhancement via Slurry‐Applicable Thiol‐Ene Click Chemistry for Low‐Pressure‐Operable All‐Solid‐State Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Cross‐linked binders with enhanced resiliencies under low operating pressures are designed via in situ thiol‐ene click reactions within slurries. Cross‐linking improves the Young's moduli and elasticities of the styrene‐butadiene rubber binders, effectively mitigating interparticle delamination within the composite cathodes induced by volumetric ...

The multiple melting behaviour of immiscible poly(ether ether ketone)/poly(ether diphenyl ether ketone) blend

open access: yesPolymer, 1997
Poly(ether ether ketone)/poly(ether diphenyl ether ketone) blend containing 30wt% PEDEK was used to investigate the melting behaviour of immiscible PEEK/PEDEK blends. The results measured from differential scanning calorimetry (d.s.c.) and wide-angle X-ray diffraction (WAXD) showed that immiscible PEEK/PEDEK blends isothermally crystallized at a ...
