Influence of DMAc on Rheological and Thermal Behaviors of PA12 for Laser Powder Processability

Journal of Applied Polymer Science, EarlyView.
ABSTRACT The study investigated the influence of dimethylacetamide (DMAc) on the rheological behavior of molten polyamide 12 (PA12), its effects on powder morphology, and thermal properties to establish its processability for additive manufacturing. Both the storage modulus (G′) and loss modulus (G″) exhibited nonlinear viscoelastic behavior due to ...

A deforming‐mesh finite‐element approach applied to the large‐translation and free‐surface scenario of fused deposition modeling

International Journal for Numerical Methods in Fluids, Volume 95, Issue 2, Page 334-351, February 2023., 2023
A boundary‐conforming free‐surface finite element method applied to fused deposition modeling (FDM) is presented. Using a boundary‐conforming approach shows to have several advantages in an FDM simulation. In particular, boundary conditions, like heat fluxes or free‐surface, can be directly imposed on the boundary.

Durotaxis in viscoelastic fluids [PDF]

arXiv
Organisms often swim through fluids that are spatially inhomogeneous. If the fluids are polymeric, gradients in polymer concentration may lead to gradients in both fluid viscosity and elasticity. In this letter, we present theoretical results for the dynamics of active particles, biological or otherwise, swimming through spatially inhomogeneous ...

Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect

Advanced Physics Research, EarlyView.
This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

Mesoscale simulation model for odd fluids [PDF]

arXiv
A fluid, with broken time-reversal symmetry, would exhibit odd transport coefficients, such as odd viscosity, thermal conductivity and diffusion coefficient, which may fundamentally alter the fluid properties and significantly influence the structure and dynamics of immersed objects.

Stellar Physics and General Relativity

Astronomische Nachrichten, EarlyView.
ABSTRACT The general theory of relativity is currently established as the most precise theory of gravity supported by observations, and its application is diverse ranging from astronomy to cosmology, while its application to astrophysics has been restricted only to compact stars due to the assumption that the Newtonian approximation is sufficient for ...
