Plasma nitriding of Al 99.5 [PDF]

Le Journal de Physique IV, 1993
Aluminium nitride (AlN) is a very interesting ceramic because of its combination of properties such as high thermal stability, high hardness and an unusual combination of high thermal and low electrical conductivity. But it is very difficulty to obtain an AlN layer on the aluminium substrates by thermochemical nitriding process.

Physical and tribological properties of Nitrided AISI 316 stainless steel balls [PDF]

, 2016
AISI 316 austenitic stainless steel balls (diameters 5.0 and 12.0 mm, typical hardness 250 HV0.3) and flat samples (20×20×2.0 mm) were nitrided by a pulsed glow discharge Ar/N2 plasma. Hardness of the ball surfaces was analyzed using Vickers indentation.

Microporous Microgel Assemblies Facilitating the Recruitment and Osteogenic Differentiation of Progenitor Cells for Bone Regeneration

Advanced Functional Materials, EarlyView.
There is a significant need for biomaterials with well‐defined stability and bioactivity to support tissue regeneration. In this study, we developed a tunable microgel platform that enables the decoupling of stiffness from porosity, thereby promoting bone regeneration.

Reevaluating the Activity of ZIF‐8 Based FeNCs for Electrochemical Ammonia Production

Advanced Functional Materials, EarlyView.
Though receiving much attention, the field of electrochemical nitrogen reduction reaction (eNRR) to ammonia is marked by doubts about whether this reaction is possible in aqueous media. This work sheds light on this question for iron single‐atom on N‐doped carbon (FeNC) catalysts—a class of well‐known catalysts that is also worth testing for the sister

Expanding Chemical Space of Nucleic Acid Nanoparticles for Tunable Antiviral‐Like Immunomodulatory Responses and Potent Adjuvant Activity

Advanced Functional Materials, EarlyView.
We introduce a nucleic acid nanoparticle (NANP) platform designed to be rrecognized by the human innate immune system in a regulated manner. By changing chemical composition while maintaining constant architectural parameters, we identify key determinants of immunorecognition enabling the rational design of NANPs with tunable immune activation profiles

The Microstructure and Wear Resistance of the Ti-assisted Hot Plasma Nitrided Layer

Medžiagotyra, 2019
In order to improve the wear resistance of the surface nitrided layer of 1060 aluminum matrix, the nitrogen containing thermal plasma Ti-assisted nitriding method was adopted to obtain the strengthening phases of AlN and TiN simultaneously. The influence
