Corrosion of Potential Canister Materials During Oxic to Anoxic Transient in Compacted Bentonite

Materials and Corrosion, EarlyView.
A comprehensive analytical approach was applied to investigate material degradation phenomena of cast iron and copper as potential canister materials for the safe disposal of high‐level radioactive waste, as well as compacted bentonite exposed to artificial water relevant for disposal. ABSTRACT The long‐term performance of the engineered barrier system

Comparison on the leaching kinetics of chalcocite and pyrite with or without bacteria

, 2010
The acid leaching, ferric leaching, and bioleaching of chalcocite and pyrite minerals were conducted in two sets of 3L stirred reactors The dissolution rates of copper and iron were correlated with leaching conditions In the acid leaching process, the ...

An Anisotropic Constitutive Model for Crushable Geomaterials Based on Non‐Stationary Critical State Line Concept

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT In this paper, the dependencies of granular soil behaviour on particle crushing and fabric anisotropy are formulated within a novel model based on bounding surface plasticity theory enriched by the non‐stationary critical state line (NCSL) concept.

Regulation mechanism and kinetic characteristics of pyrite oxidation mediated by aluminum-bearing minerals

Chemical Engineering Journal Advances
As the most prevalent metal sulfide mineral in mining environments, pyrite readily undergoes oxidation under surface conditions to generate acid mine drainage, resulting in a series of environmental pollution issues.

Sodium‐Based Battery Component Design: Imitating Lithium or Forging New Paths?

Small, EarlyView.
This Perspective elucidates the decisive yet underexplored impact of cation chemistry, Na+ vs. Li+ charge carriers, on the design, selection, and formulation of their corresponding battery systems, addressing common misconceptions and the pitfalls of overreliance on Li+ design principles. Leveraging the unique characteristics of Na+, it comprehensively

Microbial oxidation of Fe21 and pyrite exposed to flux of micromolar H2O2 in acidic media [PDF]

, 2013
At an initial pH of 2, while abiotic oxidation of aqueous Fe21 was enhanced by a flux of H2O2 at micromolarconcentrations, bio-oxidation of aqueous Fe21 could be impeded due to oxidative stress/damage inAcidithiobacillus ferrooxidans caused by Fenton ...

A century of structures: historical fidelity and computational fitness in the Inorganic Crystal Structure Database (ICSD)

Acta Crystallographica Section B, EarlyView.
Of 464 Inorganic Crystal Structure Database (ICSD) structures from 1913 to 1929, the vast majority are structurally sound, but a small number carry genuine topological errors whose corrective information exists in the database yet is invisible to automated queries.
