Polyurea-Functionalized Multiwalled Carbon Nanotubes [PDF]

, 2005
An in situ polycondensation approach was applied to functionalize multiwalled carbon nanotubes (MWNTs), resulting in various linear or hyperbranched polycondensed polymers [e.g., polyureas, polyurethanes, and poly(urea-urethane)-bonded carbon nanotubes].

Communication constrained robust guidance strategy using quantized artificial time delay based control with input saturation

IET Control Theory & Applications, 2021
This work proposes the use of a logarithmic quantizer to minimize the computational load on the onboard processor of missiles. The quantizer output discretizes the continuous guidance command to a finite set of predefined discrete levels.

Intensified antibunching via feedback-induced quantum interference

, 2017
We numerically show that time delayed coherent feedback controls the statistical output characteristics of driven quantum emitters. Quantum feedback allows to enhance or suppress a wide range of classical and nonclassical features of the emitted quantum ...
