Use of plasma nitriding to improve the wear and corrosion resistance of 18Ni-300 maraging steel manufactured by selective laser melting

open access: yesScientific Reports, 2021
18Ni-300 maraging steel manufactured by selective laser melting was plasma nitrided to improve its wear and corrosion resistance. The effects of a prior solution treatment, aging and the combination of both on the microstructure and the properties after ...

Evolution of the ε and γ phases in biodegradable Fe–Mn alloys produced using laser powder-bed fusion

open access: yesScientific Reports, 2021
The key feature of Fe–Mn alloys is gradual degradability and non-magneticity, with laser power bed fusion (LPBF) parameters influencing the microstructure and chemical composition.

Stochastic linear scaling for metals and non metals [PDF]

open access: yes, 2005
Total energy electronic structure calculations, based on density functional theory or on the more empirical tight binding approach, are generally believed to scale as the cube of the number of electrons.

Environmental Chemistry and Ecotoxicology of Hazardous Heavy Metals: Environmental Persistence, Toxicity, and Bioaccumulation

open access: yesJournal of chemistry, 2019
Heavy metals are well-known environmental pollutants due to their toxicity, persistence in the environment, and bioaccumulative nature. Their natural sources include weathering of metal-bearing rocks and volcanic eruptions, while anthropogenic sources ...

Metal Metal

open access: yesArtilugio, 2023
METAL METAL es una pieza electroacústica creada en 2022. El material sonoro utilizado en la composición fue grabado durante la pandemia mundial de Covid-19. Aprovechando el aislamiento obligatorio, se realizaron sesiones de improvisación rítmica, tímbrica y textural con latas de aluminio. Estas se registraron con un grabador digital Zoom H4.

Metallic hydrogen [PDF]

open access: yesJournal of Physics: Condensed Matter, 2018
For over eighty years, scientists have been trying to produce lab-made metallic hydrogen, the holy grail of alternative fuels. In that process, diamond anvils must withstand pressures greater than those at the center of the earth—no mean feat. Recent research may have finally achieved hydrogen’s metallic state.

Study of the trace metal ion influence on the turnover of soil organic matter in cultivated contaminated soils [PDF]

open access: yes, 2006
The role of metals in the behaviour of soil organic matter (SOM) is not well documented. Therefore, we investigated the influence of metals (Pb, Zn, Cu and Cd) on the dynamic of SOM in contaminated soils where maize (C4 plant) replaced C3 cultures. Three

Self-organized pseudo-graphene on grain boundaries in topological band insulators [PDF]

open access: yes, 2016
Semi-metals are characterized by nodal band structures that give rise to exotic electronic properties. The stability of Dirac semi-metals, such as graphene in two spatial dimensions (2D), requires the presence of lattice symmetries, while akin to the ...

Toxicity, mechanism and health effects of some heavy metals

open access: yesInterdisciplinary Toxicology, 2014
Heavy metal toxicity has proven to be a major threat and there are several health risks associated with it. The toxic effects of these metals, even though they do not have any biological role, remain present in some or the other form harmful for the ...
