Amphoteric refraction at the interface between isotropic and anisotropic media [PDF]

open access: green, 2005
It is found that the amphoteric refraction, i.e. the refraction can be either positive or negative depending on the incident angles, could occur at a planar interface associated with a uniaxially anisotropic positive index media (PIM) or an anisotropic ...

Modeling Surface Recombination at the p-Type Si/SiO2Interface via Dangling Bond Amphoteric Centers [PDF]

open access: goldAdvances in Condensed Matter Physics, 2014
An integral model is proposed for recombination at the silicon/silicon dioxide (Si/SiO2) interface of thermally oxidized p-type silicon via Pb amphoteric centers associated with surface dangling bonds.

Surfactant evaluation for enhanced oil recovery: Phase behavior and interfacial tension

open access: yesOpen Chemistry, 2022
Surfactant flooding is one of the successful techniques employed in enhanced oil recovery (EOR) to extract the remaining original oil in place after primary and secondary recoveries are performed. Selection of the right EOR surfactant is an important but

THE EXPLANATON OF THE SELECTION OF BASIC DETERGENTS AND SECONDARY DETERGENTS FOR THE DEVELOPMENT OF FOAM MEANS WITH MINIMUM IRRITANT ACTION [PDF]

open access: yesAnnals of Mechnikov's Institute, 2019
Introduction. Modern detergents are different from those products which satisfied the needs of consumers of the last century (for example, they had a stable foam, a bright color due to synthetic dyes, sometimes rich liquorice smells, etc.).
