Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Mechanistic Insight Into Ionizable Cationic Lipid‐Mediated Endosomal Escape via Transient Lipid Complexes

Small, EarlyView.
Coarse‐grained simulations show that the formation of transient anionic–cationic lipid pairs regulates the rate‐limiting step for the lamellar‐to‐hexagonal phase transition in mixtures of anionic and cationic lipids mimicking the endosomal membrane after fusion with lipid‐based nanoparticles, thus playing an important role in the endosomal escape of ...

High‐Resolution Microlens‐Assisted Tunable n‐Type Optical Doping in Monolayer MoS2

Small, EarlyView.
The laser‐assisted microlens array processing (LAMP) technique enables sub‐diffraction, localized n‐type optical doping of monolayer MoS2 by utilizing self‐assembled microspheres as microlenses. Controlled sulfur vacancy formation under low‐power laser irradiation allows precise tuning of the carrier concentration.
