Enhanced initial biodegradation resistance of the biomedical Mg-Cu alloy by surface nanomodification

open access: yesJournal of Magnesium and Alloys, 2023
Mg-Cu alloys are promising antibacterial implant materials. However, their clinical applications have been impeded by their high initial biodegradation rate, which can be alleviated using nanotechnology by for example surface nanomodification to obtain a

Influence of nanocrystalline nickel powder on oxidation resistance of spark plasma sintered Ni-17Cr6.5Co1.2Mo6Al4W7.6Ta alloy

open access: yesJournal of King Saud University: Engineering Sciences, 2020
An investigation was carried out to evaluate the isothermal oxidation behavior of nickel based superalloys at 1100 °C for 120 h. The alloys which were microstructured and nanostructured were developed by spark plasma sintering system.

Amorphous-crystalline Ni-Fe powder mixture: Hydrogenation and annealing effects on microstructure and electrical and magnetic properties [PDF]

open access: yesScience of Sintering, 2016
The hydrogenation of a crystalline Ni-Fe (80 wt.% Ni, 20 wt.% Fe) powder mixture leads to the formation of a mixture of Face Centered Cubic (FCC)-Ni and FCC-Fe phase nanocrystals embedded in an amorphous matrix.

Thermoelectric behavior of Bi2Te2.55Se0.45 with a tunable seebeck coefficient: A comparison between coarse needle-like structure and bulk nanostructured alloys

open access: yesJournal of Materials Research and Technology, 2023
In this study, we compare the thermoelectric properties of coarse-grained n-type Bi2Te2.55Se0.45 alloy prepared by induction melting with the bulk-nanostructured prepared by ball milling and hot-pressing techniques.

Nanostructured crystallization of casting alloys

open access: yesLitiyo i Metallurgiya (FOUNDRY PRODUCTION AND METALLURGY), 2022
Crystallization of casting alloys has been shown to be a nanostructured process. Microcrystals of phases in the temperature range of liquidus and solidus, during eutectic and peritectic reactions, are formed from nanocrystals of components A and B of alloys, their free atoms and atomic complexes.

Plan-View Preparation of TEM Specimens from Thin Films Using Adhesive Tape [PDF]

open access: yes, 2011
A simple plan-view sample preparation technique for transmission electron microscopy (TEM) specimens is proposed for thin films by tearing-off the film with adhesive tape. The demand for very thin samples is highest for nanostructured materials where the
