Effects of microalgal diet changes on resting egg surface morphology in Artemia franciscana Kellogg, 1906 from Chile

Oceanological and Hydrobiological Studies
Resting egg surface morphological variations usually occur among different Artemia species; however, in Artemia franciscana Kellogg, 1906 from Chile, which is a typical dweller of brackish and hypersaline inland lakes and coastal lagoons in America, the ...

SURFACE MORPHOLOGY OF PbTe/Si (100) FILMS SYNTHESIZED BY MODIFIED “HOT WALL” EPITAXY TECHNIQUE

Конденсированные среды и межфазные границы, 2018
. The narrow band gap lead chalcogenide semiconductors and related solid solutions are capable to detect effectively an infrared (IR) radiation in the wavelength range 3–25 μm. Due to the unique combination of the optimal dielectric permittivity, Seebeck

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Study on surface morphology of GaN growth by MOCVD on GaN/Si(111) template

, 2006
The surface morphology of GaN grown by MOCVD on GaN/Si template was studied. Rough morphology and deep pinhole defects on some surface areas of the samples were observed and studied.

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
