Optically Bound Rapid Plasmonic Nanorod Dimers: Anisotropic Dynamics Driven by Light‐Fluidic Cooperation

open access: yesLaser &Photonics Reviews, EarlyView.
Optically confined gold nanorods exhibit cooperative light‐driven dynamics, forming mobile end‐to‐end dimers with orientation‐dependent propulsion. Using structured laser traps and an opto‐thermo‐hydrodynamic model, we uncover how optical binding, polarization‐induced torque, and near‐surface hydrodynamics govern their motion.

REDUCING TORQUE AND DRAG IN EXTENDED REACH WELLS

open access: yes
Drilling an extended reach well acquires precise engineering in drilling the deviated and horizontal section of the well as there are a lot of technical problems that can appear in these sections. The biggest issues that appear in the deviated and horizontal sections of the well are high values of friction factor that leads to high values of torque and

Application of Non‐Isothermal Network Theory With Curved‐Channel Element Characteristics to Predict Melt Conveying in High‐Performance Single‐Screw Extruders

open access: yesJournal of Polymer Science, EarlyView.
This study presents a fast and accurate calculation tool to predict conveying of polymer melts in single‐screw extruders. Integrating generalized sub‐models into network theory allows to represent the complex screw shapes and material behavior more realistically. Tests on an industrial extruder show close agreement with experiments, outperforming older

Sliding Mode Control in Aerospace Applications: A Survey

open access: yesInternational 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 ...
