Discrete Element Method Modeling of an Extrusion Process with Recirculation for Dry Manufacturing of Lithium‐Ion Battery Electrodes

Batteries &Supercaps, EarlyView.
On a digitized laboratory extruder, discrete element method modelling is studied, considering two classes of particles representing aggregates of 1) active material and 2) binder and carbon material is studied. Various extrusion scenarios leading to the formation of filaments devoted to the 3D printing of lithium‐ion battery electrodes are studied. The

“The purpose of activism is to educate”: Young people's climate activism as and for education in the youth strike movement in England

British Educational Research Journal, EarlyView.
Abstract By skipping school for their cause, young climate strikers repeatedly demonstrated their priorities in 2019 and 2020. They regularly chose to sacrifice a day of their formal education in favour of collective action. This study asks what we can learn from the reflections of former youth strikers.

Symmetries of Three Harmonically-Trapped Particles in One Dimension

, 2012
We present a method for solving trapped few-body problems and apply it to three equal-mass particles in a one-dimensional harmonic trap, interacting via a contact potential.

Design and implementation of a 3D‐printed modular distillation tower for experimental teaching in chemical engineering

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Several authors have reported the disconnection between the skills, abilities, and attitudes of graduates from STEM careers with the current needs of the labour market. In science and engineering fields, research has found the need for interdisciplinary approaches that encourage meaningful learning.

Magnetic Resonance Guided Radiation Therapy (MRgRT) Prostate Motion and Margins

Journal of Medical Radiation Sciences, EarlyView.
This study evaluated intra‐fractional prostate motion during MR‐guided radiotherapy to determine appropriate PTV margins for prostate cancer. Analysis of 18 patients resulted in calculated margins of 3.2 mm (AP), 1.7 mm (LR), and 3.2 mm (SI), supporting the potential for margin reduction with MRgRT. ABSTRACT Introduction Systematic and random errors in

Anterolateral‐Thigh Fascia Lata Free Flap Versus Fibula Free Flap for Mandibular Osteoradionecrosis

The Laryngoscope, EarlyView.
The anterolateral thigh fascia lata “rescue” free flap has been employed as a novel tool in the treatment of advanced partial thickness mandibular osteoradionecrosis. Compared with the traditional fibula free flap for the same indication, the “rescue” flap provides similar outcomes in terms of disease resolution, superior functional outcomes, and ...

Machine Learning Prediction of Raster Angle Effects on Mechanical Properties of Extrusion‐Based Additively Manufactured Conductive Thermoplastic Polyurethane Composites

Macromolecular Materials and Engineering, EarlyView.
This study integrates machine learning (ML) and high‐fidelity experiments to model how raster angle influences the mechanical properties of fused filament fabricated conductive TPU composites. Using Poly6 and SVR models, the approach accurately predicts stiffness, strength, and ductility.

The dynamical fate of planetary systems in young star clusters

, 2015
We carry out N-body simulations to examine the effects of dynamical interactions on planetary systems in young open star clusters. We explore how the planetary populations in these star clusters evolve, and how this evolution depends on the initial ...

Study on the Shape Memory Performance of 4D‐Printed Auxetic Cellular Structures with Energy Absorption Application

Macromolecular Materials and Engineering, EarlyView.
4D‐printed auxetic cellular structures made from PETG demonstrate almost complete recovery of shape and mechanical properties after repeated loading. Two strategies successfully addressed the low shape‐fixity issue, the primary limitation of cold programming.
