Journal ArticleDOI
A critical appraisal of polymer-clay nanocomposites.
Biqiong Chen,Julian R. G. Evans,H. Christopher Greenwell,Pascal Boulet,Peter V. Coveney,Allen Bowden,Andrew Whiting +6 more
TL;DR: This critical review attempts to assess issues from the viewpoint of traditional composites thereby embedding these new materials in a wider context to which conventional composite theory can be applied.
Journal ArticleDOI
Molecular Dynamic Simulations of Montmorillonite–Organic Interactions under Varying Salinity: An Insight into Enhanced Oil Recovery
TL;DR: In this article, three mechanisms proposed to account for low-salinity enhanced oil recovery in sandstone reservoirs are investigated using molecular dynamic simulations, i.e., electric double layer expansion, multicomponent ionic exchange, and pH effects arising at clay mineral surfaces.
Journal ArticleDOI
Preparation of zinc oxide free, transparent rubber nanocomposites using a layered double hydroxide filler
Amit Das,De-Yi Wang,De-Yi Wang,Andreas Leuteritz,Kalaivani Subramaniam,H. Christopher Greenwell,Udo Wagenknecht,Gert Heinrich +7 more
TL;DR: In this article, a layered double hydroxide (LDH) mineral filler particle has been designed and employed in rubber vulcanization to prepare a more environmentally friendly rubber composite and morphological characterization, rheometric curing behavior, mechanical properties and uniaxial multi-hysteresis behaviors of the resultant rubber/LDH nanocomposite are studied.
Journal ArticleDOI
Towards a mechanistic understanding of carbon stabilization in manganese oxides
Karen L. Johnson,Graham Purvis,Elisa Lopez-Capel,Caroline L. Peacock,Neil D. Gray,Thomas Wagner,Christian März,Leon Bowen,Jesus J. Ojeda,Nina Finlay,Steve Robertson,Fred Worrall,H. Christopher Greenwell +12 more
TL;DR: In this article, the authors show that manganese oxide (Mn oxide) in a water treatment works filter bed traps dissolved organic carbon (OC) as coatings build up in layers around clean sand grains at 3%w/wC.
Journal ArticleDOI
Mineral surface chemistry control for origin of prebiotic peptides
TL;DR: It is shown that layered double hydroxides, a type of clay little studied despite its presumed prevalence on the early Earth, can facilitate the formation of small proteins.
