Stabilizing and structuring oil–oil interfaces by molecular brush surfactants
Aggregate, Volume 3, Issue 6, December 2022., 2022 Using the co‐assembly of polar molecular brushes and nonpolar oligomeric ligands, molecular brush surfactants (MBSs) form and assemble in situ at the DMF–octane interface via electrostatic interaction/hydrogen bonding. The binding energy of MBS to the interface is sufficiently high to support the compression, then to structure liquids.

Jamming-assisted Eavesdropping over Parallel Fading Channels [PDF]
arXiv, 2019 This paper advances the proactive eavesdropping research by considering a practical half-duplex mode for the legitimate monitor and dealing with the challenging case that the suspicious link opportunistically communicates over parallel fading channels. To increase eavesdropping success probability, we propose cognitive jamming for the monitor to change

Advanced Materials Technologies, EarlyView.A variable stiffness structure with shape morphing and shape memory capabilities made from layered textiles and 3D printing material is developed. Direct printing of cPLA on textile electrodes maximizes the electrodes' contact area. This work presents a new method for achieving variable stiffness in small segments of soft, deformable structures, using ...

Orbital Angular Momentum Active Anti-Jamming in Radio Wireless Communications [PDF]
arXivOrbital angular momentum (OAM), providing the orthogonality among different OAM modes, has attracted much attention to significantly increase spectrum efficiencies (SEs) and enhance the anti-jamming results of wireless communications. However, the SE of wireless communications is severely degraded under co-frequency and co-mode hostile jamming. Focused
