Low‐Energy Atomic Scattering: S‐Wave Relation Between the Interaction Potential and the Phase Shift

open access: yesAnnalen der Physik, EarlyView.
The validity of the on‐shell approximation for s‐wave scattering is examined across one, two, and three dimensions using exactly solvable model interaction potentials. By comparing exact and approximate s‐wave components of the interaction potential, the analysis reveals that the approximation improves with increasing momentum and decreasing ...

Micromechanical Modeling of the Elasto‐Viscoplastic Stress–Strain Response of α‐iPP

open access: yesJournal of Applied Polymer Science, EarlyView.
Micromechanical modelling of α‐iPP. ABSTRACT The mechanical properties of semi‐crystalline polymers are dictated by the individual characteristics of crystalline and amorphous phases and the complex interplay between them. Processing conditions can strongly influence micro‐structural features such as crystallinity and orientation of crystalline ...

Solid State Polymerization on Poly(Lactic Acid)‐Based Microcapsules: Process Parameters Adjustment in Order to Design Coumarin‐6 Encapsulation System

open access: yesJournal of Applied Polymer Science, EarlyView.
This work emphasizes solid state polymerization (SSP) as a modification tool for altering the properties of PLA microcapsules (MCs). Therefore, the SSP process is optimized in order to avoid particle aggregation, and its kinetics is studied. Also, loaded MCs are subjected to SSP, resulting in changing release rate.

Linear Matrix Inequality‐based design of distributed proportional‐integral‐derivative for the output consensus tracking in heterogeneous high‐order multi‐agent systems

open access: yesAsian Journal of Control, EarlyView.
Abstract This article addresses the cooperative output consensus tracking problem for high‐order heterogeneous multi‐agent systems via a distributed proportional‐integral‐derivative (PID)‐like control strategy and proposes two novel control methodologies for the tuning of the control gains, which do not require any assumption and/or limitation on agent
