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

open access: yesAdvanced 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,

Kinetics of film growth in CVD reactions

open access: yes, 1999
Theoretical aspect of film growth kinetics is discussed. Two approaches : microstuctural and transport phenomena are presented. An original model defined by the simplified laminar boundary layer theory is suggested.

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

open access: yesAdvanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

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

open access: yesAdvanced 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 ...

Growth Kinetics of African Swine Fever Virus (Genotype II) Isolated from a Domestic Pig in Punjab, India

open access: yesJournal of Pure and Applied Microbiology
African swine fever (ASF), a deadly disease caused by African swine fever virus (ASFV), emerged in north-eastern India in 2020 and subsequently spread to several states, devastating swine herds due to the lack of commercial vaccines.

UNIVERSAL ASPECTS OF DOMAIN-GROWTH KINETICS.

open access: yes, 1986
Scaling properties of domain growth in a variety of two-dimensional model systems were investigated by computer simulation techniques. Physical realizations of the models include molecular monolayers adsorbed on solid surfaces.

Statistical properties of microbial phenotypes and colony growth [PDF]

open access: yes, 2012
Cells are the fundamental units of which all life forms are composed. To understand the elementary organization of life, it is therefore meaningful to start the investigation on the single cell level.Modern microscopy permits the examination of both ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

In0.49Ga0.51P growth on pre-patterned GaAs substrates by chemical beam epitaxy

open access: yes, 2015
We present a study on the growth of lattice-matched InGaP on patterned GaAs substrates by chemical beam epitaxy. An experimental analysis of the growth on planes [100] and [111]A as a function of growth temperature and pattern dimension is presented.
