Advanced Engineering Materials, EarlyView.This study presents rapid evaluation methods for scan strategies in powder bed fusion (PBF) of polymers with a NIR laser as an example for its application. It uses line buffer‐based calculations and point density fields to predict the performance of four different scan strategies. The methods show promising results in laser‐based PBF of polymer samples,

Advanced Engineering Materials, EarlyView.Periodic submicron features are fabricated on 304 stainless steel using single and double femtosecond laser pulses. By adjusting polarization, fluence, and inter‐pulse delay, 1D and 2D nanostructures are formed. Enhanced hydrophobicity and dense surface‐enhanced Raman spectroscopy hotspots enable analyte detection down to 10−10 M with good ...

Additive Manufacturing of Highly Alloyed Aluminum–Lithium
Advanced Engineering Materials, EarlyView.Al–Li alloys, promising for future lightweight constructions due to their low density and high stiffness, are limited to 9 at% lithium in commercial forms because of segregation issues. To overcome this traditional limitation, powder bed fusion with an ultrashort pulse laser is used.

Oscillatory bifurcation for semilinear ordinary differential equations
Electronic Journal of Qualitative Theory of Differential Equations, 2016 We consider the nonlinear eigenvalue problem \[u''(t) + \lambda f(u(t)) = 0, \quad u(t) > 0, \quad t \in I := (-1,1), \quad u(1) = u(-1) = 0, \] where $f(u) = u + (1/2)\sin^k u$ ($k \ge 2$) and $\lambda > 0$ is a bifurcation parameter.

Advanced Engineering Materials, EarlyView.Multilayering of TiN film with metallic Ti film is adopted to enhance the fracture resistance of TiN thin films. Plastic dissipation within Ti with process zone size of ≈250 nm, along with elastic–plastic mismatch driven changes to crack driving force enhances the crack growth resistance by ten times, enabling physics informed design of optimized ...

Advanced Engineering Materials, EarlyView.This study reveals how wave propagation in FG‐MEE nanoplates can be tuned via material gradients, porosity, and external fields. Using NSGT and Hamilton's principle, analytical solutions capture key dispersion behaviors. Findings highlight the potential of smart nanoplates for adaptive control in high‐performance applications like sonar and aerospace ...
