Optoelectronic Characterization and Properties of Single-walled Carbon Nanotubes in a Liquid Dispersion Form

open access: yesInternational Journal of Technology, 2023
Carbon nanotubes (CNTs) are very promising nanodevices due to their extraordinary electrical, thermal, and optical properties. However, as-grown single-walled CNTs (SWCNTs) contain a mixture of semiconducting and metallic species with great features ...

THE ROLE OF MONOVALENT IONS IN THE DETERIORATION OF SOME PHYSICAL PROPERTIES OF CALCAREOUS SOILS IN NORTHERN IRAQ [PDF]

open access: yesMesopotamia Journal of Agriculture
Twelve soil samples of different textures and carbonate minerals were selected from the great soil group (Calciortheds) in northern Iraq. In order to describe the effect of the concept of mono cations ratios (potassium and sodium) responsible for the ...

Distance-2-Dispersion: Dispersion with Further Constraints

open access: yes, 2023
The aim of the dispersion problem is to place a set of $k(\leq n)$ mobile robots in the nodes of an unknown graph consisting of $n$ nodes such that in the final configuration each node contains at most one robot, starting from any arbitrary initial configuration of the robots on the graph.

Frequency-Oriented Subsampling by Photonic Fourier Transform and I/Q Demodulation

open access: yesIEEE Photonics Journal, 2017
Subsampling can directly acquire a passband within a broad radio frequency (RF) range, avoiding down-conversion and low-phase-noise tunable local oscillation. However, subsampling suffers from band folding and self-image interference.
