Carbon dioxide sequestration through silicate degradation and carbon mineralisation: promises and uncertainties

10.1038/s41529-018-0035-4

2018-04-04

Turning carbon dioxide (CO2) into rocks: controlling this process, which naturally operates at the Earth’s surface over geological timescales, is likely to represent a major technological challenge of this century. One of the recurring criticisms with the car...

Tracking the evolution of intergranular corrosion through twin-related domains in grain boundary networks

10.1038/s41529-018-0032-7

2018-04-03

Tailoring the grain boundary network is desired to improve grain boundary-dependent phenomena such as intergranular corrosion. An important grain boundary network descriptor in heavily twinned microstructures is the twin-related domain, a cluster of twin-rela...

Passivation behaviour of aluminium current collector in ionic liquid alkyl carbonate (hybrid) electrolytes

10.1038/s41529-018-0033-6

2018-03-29

The compatibility of current collectors with the electrolyte plays a major role in the overall performance of lithium batteries, critical to obtain high storage capacity as well as excellent capacity retention. In lithium-ion batteries, in particular with cat...

In situ electrochemical dissolution of platinum and gold in organic-based solvent

10.1038/s41529-018-0031-8

2018-03-21

In situ highly sensitive potential- and time-resolved monitoring of polycrystalline gold and platinum electrochemical dissolution in pure organic media is reported. This was achieved by successfully upgrading electrochemical flow cell coupled to inductively c...

Understanding the reactivity of CoCrMo-implant wear particles

10.1038/s41529-018-0029-2

2018-03-12

CoCrMo-based metal-on-metal hip implants experienced unexpectedly high failure rates despite the high wear and corrosion resistance of the bulk material. Although they exhibit a lower volumetric wear compared to other implant materials, CoCrMo-based implants ...

Time-dependent in situ measurement of atmospheric corrosion rates of duplex stainless steel wires

10.1038/s41529-018-0030-9

2018-03-07

Corrosion rates of strained grade UNS S32202 (2202) and UNS S32205 (2205) duplex stainless steel wires have been measured, in situ, using time-lapse X-ray computed tomography. Exposures to chloride-containing (MgCl2) atmospheric environments at 50 °C (12–15 M...

Chemical durability of peraluminous glasses for nuclear waste conditioning

10.1038/s41529-018-0028-3

2018-03-02

For the handling of high level nuclear waste (HLW), new glass formulations with a high waste capacity and an enhanced thermal stability, chemical durability, and processability are under consideration. This study focuses on the durability of peraluminous glas...

Integrated computational materials engineering of corrosion resistant alloys

10.1038/s41529-018-0027-4

2018-02-20

Structure, composition and surface properties dictate corrosion resistance in any given environment. The degrees of freedom in alloy design are too numerous in emerging materials such as high entropy alloys and bulk metallic glasses for the use of high-throug...

The role of titanium in the initiation of localized corrosion of stainless steel 444

10.1038/s41529-018-0026-5

2018-02-14

Titanium has been added to ferritic stainless steels to combat the detrimental effects of intergranular corrosion. While this has proven to be a successful strategy, we have found that the resulting Ti-rich inclusions present on the surface play a significant...

Structure of International Simple Glass and properties of passivating layer formed in circumneutral pH conditions
