Exploring the 5Cr steel as supercritical CO2 geothermal extraction pipeline from corrosion point of view: Effects of phase environment, temperature and Cl−

open access: yesJournal of Materials Research and Technology
The corrosion performance of 5Cr steel as injection/production pipeline material for Supercritical CO2 (S–CO2) geothermal extraction has been systematically investigated in both S–CO2 and H2O phases at 23 MPa. The results show that H2O phase induces more

Process mapping of laser surface modification of AISI 316L stainless steel for biomedical applications [PDF]

open access: yes, 2009
A 1.5-kW CO2 laser in pulsed mode at 3 kHz was used to investigate the effects of varied laser process parameters and resulting morphology of AISI 316L stainless steel. Irradiance and residence time were varied between 7.9 to 23.6 MW/cm2 and 50 to 167 µs

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

open access: yesAdvanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

CO2 Impact on FeCO3 Corrosion Product

open access: yes, 2021
Reduction of the emissions of CO2 and other greenhouse gases is a global challenge. Carbon capture and storage (CCS) is one of the most ready to use technologies applicable for industries such as biogas upgrading, cement, and in general, gas cleaning. Even though the technology is mature, optimization is still needed to reduce costly production losses ...

Tribo-corrosion properties of cobalt-based medical implant alloys in simulated biological environments [PDF]

open access: yes, 2007
Tribological problems and corrosion degradation have been recognized as essential risks for total joint replacements, especially for all-metal arthroplasty. Few studies have focused on the interactions between tribology and corrosion (tribocorrosion) for

A Termite‐Inspired Alternative to Cement

open access: yesAdvanced Functional Materials, EarlyView.
A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,

Role of direct microbial electron transfer in corrosion of steels [PDF]

open access: yes, 2009
It has recently been discovered that many microbial species have the capacity to connect their metabolism to solid electrodes, directly exchanging electrons with them through membrane-bound redox compounds,nevertheless such a direct electron transfer ...
