Vacuum condensates and `ether-drift' experiments [PDF]
Phys.Lett.A318:292-299,2003, 2003 The idea of a `condensed' vacuum state is generally accepted in modern elementary particle physics. We argue that this should motivate a new generation of precise `ether-drift' experiments with present-day technology.

Single-pass transformation of syngas into ethanol with high selectivity by triple tandem catalysis
Nature Communications, 2020 Direct synthesis of ethanol from non-petroleum carbon resources via syngas (CO/H2) is a highly attractive but challenging target. Here, the authors report a triple tandem catalytic system for single-pass conversion of syngas into ethanol with selectivity

On the formation and propagation of pulses in ether [PDF]
arXiv, 2021 In 1746 Euler publishes E88 -- Nova theoria lucis et colorum (A new theory of light and colors) in five chapters. This is an annotated translation of Chapter II - De formatione ac propagatione pulsuum (On the formation and propagation of pulses in ether), in which Euler considers that the propagation of light in ether is similar to the propagation of ...

Convenient method for preparing benzyl ethers and esters using 2-benzyloxypyridine
Beilstein Journal of Organic Chemistry, 2008 2-Benzyloxy-1-methylpyridinium triflate (1) is emerging as a mild, convenient, and in some cases uniquely effective new reagent for the synthesis of benzyl ethers and esters. This article provides a revised benzyl transfer protocol in which N-methylation
