Effect of side chains on the dielectric properties of alkyl esters derived from palm kernel oil [PDF]
, 2011 Alkyl ester derivatives were synthesized from laboratory purified palm kernel oil. The steps in the synthesis involved transesterification of palm kernel oil to produce a methyl ester, followed by epoxidation and then the grafting of side chains by ...

Advanced Functional Materials, EarlyView.The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

Effect of different contents of nano-SiO2 particles on water diffusion behavior in insulating oil
AIP Advances, 2019 As an important component of the internal insulation system in a transformer, insulating oil will gradually age during the long-term operation of the transformer, which will lead to a degradation of its insulation performance.
