Red mud as a carbon sink : variability, affecting factors and environmental significance

, 2012
The capacity of red mud to sequester CO2 varied markedly due to differences in bauxite type, processingand disposal methods. Calcium carbonates were the dominant mineral phases responsible for the carbonsequestration in the investigated red mud types ...

Electrokinetic Stabilization of Formation Fines Using Surface Modified Polymer Silica Nanocomposites During Low Salinity Water Flooding for Enhanced Oil Recovery

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Fines migration induced by low salinity water flooding severely impairs reservoir permeability and injectivity presenting a critical challenge in enhanced oil recovery. This study aims to synthesize and evaluate a surface‐modified polymer‐silica nanocomposite to mitigate clay mobilization and preserve the hydrodynamic capacity of porous media.

Description of large, well‐preserved Enchodus specimens from the Bearpaw Formation of Alberta, Canada

The Anatomical Record, EarlyView.
Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Bite force estimates and morphological correlations of jaw muscles in parrots

The Anatomical Record, EarlyView.
Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.

Hydrocarbon cracking over red mud and modified red mud samples [PDF]

, 2016
The aluminum industry generates large quantities of red mud during the beneficiation of bauxite ore. The red mud is disposed of as a waste in dry or wet form.

Exceptional preservation informs the paleobiology of tapinocephalid dinocephalians

The Anatomical Record, EarlyView.
Abstract The tapinocephalid dinocephalian Moschops is one of the most iconic taxa of the middle Permian, yet its paleobiology remains one of the least well‐known. Here, we address some aspects of paleoneurology and paleobiology of Moschops using CT scanning of four well preserved skulls from the upper Abrahamskraal Formation of South Africa. Two of the

A new occurrence of tetrapod footprints from the Late Triassic of the Candelária Sequence, Brazil

The Anatomical Record, EarlyView.
Abstract The Hyperodapedon Assemblage Zone of the Candelária Sequence (Santa Maria Supersequence, Paraná Basin) preserves one of the most significant Late Triassic continental vertebrate assemblages in southern Brazil. Despite the relatively well‐documented body fossil record from this interval, ichnological records remain comparatively scarce.

Absorption of CO2 in a bubble column using red mud

REM: International Engineering Journal
In the industrial production of aluminum through the Bayer process, two main pollutants are generated, red mud and carbon dioxide (CO2). Conventional processes for treating polluting waste include the neutralization of red mud with hydrochloric acid (HCl)
