Nanoscale active tuning of the second harmonic generation efficiency in semiconductors from super-low to gigantic values

open access: yesNew Journal of Physics, 2022
Second harmonic generation efficiency (SHGE) strongly depends on the length of the interaction material along the beam propagation axis. Since a nanoscale interaction length is considered too short even in the optical wavelength scale, the attained SHGE ...

Insights into Nanoscale Wettability Effects of Low Salinity and Nanofluid Enhanced Oil Recovery Techniques

open access: yesEnergies, 2020
In this study, enhanced oil recovery (EOR) techniques—namely low salinity and nanofluid EOR—are probed at the nanometer-scale using an atomic force microscope (AFM). Mica substrates were used as model clay-rich rocks while AFM tips were coated to present

Extreme emulsification: formation and structure of nanoemulsions

open access: yesCondensed Matter Physics, 2006
Nanoemulsions are metastable dispersions of nanodroplets of one liquid that have been ruptured by shear in another immiscible liquid. The ruptured droplets are stabilized against subsequent coalescence by a surfactant.

A brief review on the recent development of phonon engineering and manipulation at nanoscales

open access: yesInternational Journal of Extreme Manufacturing, 2023
Phonons are the quantum mechanical descriptions of vibrational modes that manifest themselves in many physical properties of condensed matter systems. As the size of electronic devices continues to decrease below mean free paths of acoustic phonons, the ...
