NanoSteels (The Newest Approaches Toward the Training and Applications of Nanotechnology in Mass Production of Nanostructure Steels) [PDF]

open access: yesFanāvarī-i āmūzish, 2010
The term NanoSteels is called to some special steels consisting of nanosize phases (i.e. ferrite, cementite, and austenite), grains, and carbides (e.g. vanadium and M2C) produced by nanotechnology.

Angle‐dependent X‐ray absorption correction in small‐ and wide‐angle X‐ray scattering: accounting for constrained scattering volume, beam profiles and capillary wall attenuation

open access: yesJournal of Applied Crystallography, Volume 59, Issue 5, Page 1374-1383, October 2026.
We present an improved numerical angle‐dependent absorption correction procedure for line‐collimated small‐ and wide‐angle X‐ray scattering measurements in thin‐walled quartz capillaries. The procedure accounts for the constrained illuminated volume, measured primary beam profiles and capillary‐wall absorption, enabling physically consistent data ...

Spectroscopy of hot subdwarf binaries

open access: yesOpen Astronomy, 2018
We present a status report of our spectroscopic analysis of subdwarf binaries consisting of a subdwarf and a F/G/K-type main-sequence companion. These systems selected from SDSS photometry show significant excess in the (infra-)red which can not be ...

Micro‐Galvanic Coupling Programs the Therapeutic Zinc Ion Window to Reconfigure Immune Cascades for Pro‐Regenerative Bone Healing

open access: yesAdvanced Science, Volume 13, Issue 50, 7 September 2026.
This study utilized alloy micro‐galvanic coupling design to regulate the release of essential elements, thereby programming immune responses and promoting regeneration. The sacrificial anodic process of Zn‐0.8Mg reduced Zn2+ release compared to the “large cathode‐small anode” coupling of Zn‐0.8Fe.

Grain Refinement During Severe Plastic Deformation and Similitude of Subgrain Formation: A Molecular Dynamics Study

open access: yesAdvanced Engineering Materials, Volume 28, Issue 15, 5 August 2026.
Molecular dynamics is used to investigate structure refinement during severe plastic deformation. The results show similitude with experimental data. Molecular dynamics simulations of severe plastic deformation of monocrystalline and polycrystalline samples by multiaxial compression of aluminum are carried out.

Bioresorbable Scaffolds for Coronary Arteries: Where Do We Stand Today?

open access: yesVIEW Medicine, Volume 1, Issue 1, August 2026.
Bioresorbable coronary scaffolds are moving from thick strut pitfalls to thinner, stronger, healing‐oriented designs. Integrating advances in materials, guided implantation with preparation, size, and postdilation steps, and resorption aligned to healing, we synthesize clinical evidence and chart a roadmap toward intelligent, transient platforms ...

A uniformly fine-grained Mg-Y-Nd-Zr magnesium alloy with simultaneously optimized strength and ductility processed by forging and ECAP

open access: yesMaterials Research Express, 2020
In this work, as-cast rare earth Mg-2Y-0.6Nd-0.5Zr alloy was successfully processed by forging at 350 °C and different numbers of passes of equal channel angular pressing (ECAP) along the Bc route.
