Advanced Engineering Materials, EarlyView.A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Advanced Engineering Materials, EarlyView.Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Advanced Engineering Materials, EarlyView.Sustainability assessment requires methodologies that appropriately distinguish between additive and non‐additive material properties. A toxicity‐weighted scoring system is developed and applied that accounts for the disproportionate influence of highly toxic constituents through nonlinear weighting functions, providing more realistic estimates than ...

Design of a Multistable Finger Prosthesis with Programmable Metamaterials
Advanced Engineering Materials, EarlyView.This research article shows the development of a multistable programmble metamaterial for the use as a finger prosthesis. The material was designed on different hierarchical levels where the influence of geometrical parameters and combination of mechanical elements was explored.

When singular points determine quadratic systems
Electronic Journal of Differential Equations, 2008 When one considers a quadratic differential system, one realizes that it depends on 12 parameters of which one can be fixed by means of a time change.

BERNULLI DIFFERENTIAL EQUATION AND CHAOS
Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Modelûvannâ, 2013 Existence conditions of homoclinic orbits for some systems of ordinary quadratic differential equations with singular linear part are founded. A realization of these conditions guarantees the existence of chaotic attractors at 3-D autonomous quadratic ...

Quadratic Systems with Center and Their Perturbations
Journal of Differential Equations, 1994 By writing the general quadratic system on a plane having a singular point of center or focus type in the complex form (1) \(\dot z= (i+\lambda) z+ Ax^ 2+ Bz\bar z+ C\bar z^ 2\), \(\lambda\in\mathbb{R}\), \(A,B,C\in\mathbb{C}\), \(z= x+iy\), first, the author gives a simple algebraic proof of the classical Dulac and Kapteyn theorem: Theorem 1.

Investigating the Low‐Temperature Phase Stability of the Binary Ta–W System
Advanced Engineering Materials, EarlyView.Atomistic simulations show that the binary Ta–W system forms ordered intermetallic phases, B2‐TaW and D03‐TaW3, as 0 K ground states. Configurational entropy, however, lowers the free energy of the disordered bcc solid solution, which becomes the stable phase above about 400 K.
