Advanced Engineering Materials, EarlyView.This article examines how build orientation, thickness, and loading rate affect the tensile and compressive properties of LS‐manufactured polyamide 12 12 parts. Through over 120 experiments, it reveals strong ductility anisotropy in tension, minimal compressive sensitivity, and significant thickness and strain rate dependencies.

Electrical and topological properties of oxides films grown thermally on InSe substrates [PDF]
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2010 The surface resistance dynamics of oxides grown thermally on InSe substrates in two crystallography planes is obtained. It is determined that resistance changes considerably only during the first 5 minutes of the oxidization period.

Magnetic surface topology in decaying plasma knots
New Journal of Physics, 2017 Torus-knot solitons have recently been formulated as solutions to the ideal incompressible magnetohydrodynamics (MHD) equations. We investigate numerically how these fields evolve in resistive, compressible, and viscous MHD. We find that certain decaying

A continuity property and surface topology [PDF]
Bulletin of the American Mathematical Society, 1973 Introduction. While studying global properties of spaces of retractions of 2-manifolds, the author was led to a continuity property for conformai mappings of simply connected domains with locally connected boundaries (§1, Theorem 2). Applications are given to the study of spaces of retractions (§2), spaces of retracts (§3), and the Dirichlet problem ...

Advanced Engineering Materials, EarlyView.Additive manufacturing (AM) transforms space hardware by enabling lightweight, high‐performance, and on‐demand production. This review outlines AM processes—powder bed fusion (PBF), directed energy deposition (DED), binder jetting (BJ), sheet lamination (SL), and material extrusion (ME)—applied to propulsion, satellite structures, and thermal devices ...

Applied Sciences, 2021 In the fabrication of semiconductors, chemical mechanical polishing (CMP) is an essential wafer-planarization process. For optimal CMP, it is crucial to monitor the texture of the polishing pad; this leads to homogenous planarization of wafers. Hence, we

Advanced Engineering Materials, EarlyView.This study explores the ablation efficiency and surface quality of laser‐treated stainless steel alloys (AISI 304, AISI 420, and AISI 316Ti) using an ultrashort pulsed laser and varying burst parameters (MHz, GHz, and Bi‐burst). Both ablation rates and surface quality parameters are determined, including isotropy surface roughness values, highlighting ...

, 2009 In layered single band systems, the interlayer conductivity depends on the orientation of the in-plane magnetic field and takes maximum values when the magnetic field is perpendicular to flat regions of the Fermi surface.
