Time-resolved in situ studies on the formation mechanism of iron oxide nanoparticles using combined fast-XANES and SAXS [PDF]

, 2015
The reaction of iron chlorides with an alkaline reagent is one of the most prominent methods for the synthesis of iron oxide nanoparticles. We studied the particle formation mechanism using triethanolamine as reactant and stabilizing agent.

Phase Stability Study of the Marcasite‐Structure Solid Solutions (Fe,TM)Sb2 (TM = Cr, Ni) Synthesized via Combinatorial Co‐Deposition and Antimonization

Advanced Engineering Materials, EarlyView.
Phase diagrams of transition‐metal di‐pnictides have been efficiently and quickly explored by combinatorial deposition of transition‐metal films and subsequent antimonization enabling the study of compounds with volatile elements. In (Fe,Ni)Sb2 and the (Fe,Cr)Sb2 substitution series, phase separation has been evidenced between class‐A and B marcasites ...

Influence of a Standard Heat Treatment on the Microstructure and Properties of Inconel X‐750 Produced by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Ni‐base superalloys produced using additive manufacturing (AM) have a different response to heat treatments when compared to their conventional counterparts. Due to such unpredictability, various alloys with industrial interest are currently overlooked in most prior AM research.

Versatile X-ray reflector extension setup for grazing-incidence experiments at SAXS facilities for liquid surface study

Journal of Synchrotron Radiation
Existing beamlines for in situ grazing-incidence small-angle scattering on liquids are either limited in angular range or incompatible with the large sample–detector distance required for submicrometre resolution.

Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components

Advanced Engineering Materials, EarlyView.
This study examines microstructurally graded 316L rectangular tube profiles fabricated via PBF–LB/M using a dual‐laser system. A 1 kW top‐hat and a 400 W Gaussian laser create distinct grain sizes and crystallographic texture. Mechanical properties are linked to microstructural evolution driven by processing conditions.

W‐Based Thin Film Metallic Glasses Doped with Ni, Zr, and B for Industrial Applications

Advanced Engineering Materials, EarlyView.
This work is the first to deal with a comprehensive comparison of two metallic glass systems, W–Zr–B and W–Ni–B, in terms of their suitability for specific industrial applications. Their mechanical and tribological properties are compared and discussed in combination with structural homogeneity on different types of technically relevant substrates and ...

Size and Concentration Determination of Colloidal Nanocrystals by Small-Angle X-ray Scattering

Chemistry of Materials, 2018
The accurate determination of the dimensions of a nano-object is paramount to the development of nanoscience and technology. Here we provide procedures for sizing quasi-spherical colloidal nanocrystals (NCs) by means of small-angle X-ray scattering (SAXS)

Optimized Strategy for Fabricating High‐Aspect‐Ratio Periodic Structures Over Large Areas Using ps‐Direct Laser Interference Patterning

Advanced Engineering Materials, EarlyView.
Picosecond direct laser interference patterning (DLIP) enables precise microstructure fabrication on stainless steel. Using a multiscan approach, high‐aspect‐ratio patterns are achieved. Fluence influences structure growth and homogeneity, with smaller periods yielding better uniformity.
