A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

The Cloud Radiative Response to Surface Warming Weakens Hydrological Sensitivity

Geophysical Research Letters
Precipitation is expected to increase in a warmer global climate, yet how sensitive precipitation is to warming depends on poorly constrained cloud radiative processes.

Radiative Processes in Cool Coronal Condensations

Solar Physics
Abstract Increasing interest in understanding the formation and dynamics of cool coronal condensations like solar prominences leads to complex magneto-hydrodynamical (MHD) simulations which assume a variety of physical processes responsible for energy balance.

Isotope effect on the formation of CN by radiative association reactions

AIP Advances
The formation of CN and its isotopologue C15N through radiative association has been investigated. We considered two processes for the collisions of ground state C(3P) and N(4S) atoms (A2Π → X2Σ+ and b4Π → a4Σ+), as well as, for the first time, we ...

How two-dimensional are planet–disc interactions?

Astronomy & Astrophysics
Context. The ring and gap structures found in observed protoplanetary disks are often attributed to embedded gap-opening planets and typically modeled with simplified thermodynamics and in the 2D, thin disk approximation.

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Kinetic model of radiative recombination processes in 2H-MoS2 crystals

Moldavian Journal of the Physical Sciences, 2006
Steady-state photoluminescence (PL) measurements revealed 2H-MoS2 crystals. Two distinct radiative regions in the near infrared are performed. The first region consisting of several sharp lines is produced by bound excitons related to the halogen ...
