Surfactants as a Tool for Coupling Light Into Hydrodynamic Flow: The Influence of Surfactant Hydrophobicity and Head Polarity

open access: yesAdvanced Materials Interfaces, EarlyView.
Reversible light‐induced gradients at solid–liquid interfaces enable controllable interfacial transport via light‐driven diffusioosmosis. We demonstrate directed particle manipulation based on dynamically generated concentration gradients. The mechanism is broadly applicable to cationic, anionic, and non‐ionic surfactants with varying hydrophobicity ...

Dielectric Strength of Porcelain

Transactions of the American Institute of Electrical Engineers, 1939
FUNDAMENTALLY, the voltage-time characteristic of insulation suggests the extending of studies for fullerboard and transformer oil1,2 to other insulation materials. Porcelain is considered in this investigation since it is used extensively for line and substation insulation, in apparatus design as bushings,3 and for other insulation.

DIELECTRICS ELECTRICAL STRENGTH

Yessenov Science Journal, 2023
Abstract. In human life, even in practice, solids play an important role. Metals, dielectrics, electrical engineering, semiconductors, electrons, magnets, conductors lying close to each other are all solids. It can be argued that the basis for the foundation of scientific and technological progress is a solid body.

Dielectric strength of transformer insulation

Electrical Engineering, 1937
This paper presents a summary of the results of over 2,000 tests on the dielectric strength of transformer oil and insulating material for impulse, switching, and 60-cycle voltages. From these tests the voltage-time characteristics of the 2 insulations tested may be established over the entire range from a fraction of a microsecond to more than one ...
