Diethyl 4,4′-{[1,2-phenylenebis(methylene)]bis(oxy)}dibenzoate

open access: yesIUCrData
The title compound, C26H26O6, consists of two methylene(oxy)ethylbenzoate moieties in ortho position to a phenyl ring. The central phenyl ring is almost coplanar with one of the ethylbenzoate fragments, which guarantees an electron delocalization within ...

Miscibility of poly(ether ether ketone)/poly(ether diphenyl ether ketone) blends

open access: yesPolymer, 1996
Poly(ether ether ketone) and poly(ether diphenyl ether ketone) homopolymers are prepared by nucleophilic substitution routes. Miscibility of PEEK/PEDEK blends has been studied by wide-angle X-ray diffraction (WAXD) and differential scanning calorimetry (d.s.c.).

Comparative Wear and Friction Analysis of Sliding Surface Materials for Hydrostatic Bearing under Oil Supply Failure Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
Hydrostatic bearings excel in high‐precision applications, but their performance hinges on a continuous external supply. This study evaluates various material combinations for sliding surfaces to mitigate damage during supply failures or misalignment and to discover the most effective materials identified for enhancing the reliability and efficiency of

From aether theory to Special Relativity

open access: yes, 2013
At the end of the 19th century light was regarded as an electromagnetic wave propagating in a material medium called ether. The speed c appearing in Maxwell's wave equations was the speed of light with respect to the ether.

Influence of Temperature on Scratch and Wear Properties of Technical Thermoplastics: Implications for Material Selection

open access: yesAdvanced Engineering Materials, EarlyView.
The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of

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
