Organoclay flocculation as a pathway to export carbon from the sea surface [PDF]
Scientific ReportsMarine microorganisms play a critical role in regulating atmospheric CO2 concentration via the biological carbon pump. Deposition of continental mineral dust on the sea surface increases carbon sequestration but the interaction between minerals and ...

Ambient Stable Triboelectric Nanogenerator Based on Conductive Filler Modified Silicone Rubber with Gas Barrier Encapsulation for Footstep Energy Conversion. [PDF]
Adv Sci (Weinh)A humidity‐tolerant triboelectric nanogenerator is developed using conductive carbon black‐modified silicone rubber and a flame‐retardant gas barrier layer. The device efficiently harvests footstep energy while maintaining stable output under 30–90% RH and over 1 million cycles.

Organoclay-polymer nanocomposites [PDF]
Zastita Materijala, 2014 The properties of polymer nanocomposites exceed the properties of common composite materials due to the nanoscale size and morphology of the fillers used. Particulate fillersare commonly used in polymers forimproved mechanical and thermal properties, as well as modified electrical properties and cost reduction.

Surface Structure of Organoclays [PDF]
Angewandte Chemie, 2004 The properties of organically modified clay minerals determine essentially the quality of polymer-clay nanocomposites. We investigate alkylammonium-micas with different alkyl chain length by molecular dynamics simulation as homogeneous mixtures and separated island structures on the mica surface (80 percent alkali exchange, 20 percent of the alkali ...

Effect of the loading of organomodified clays on the thermal and mechanical properties of a model dental resin [PDF]
Materials Research, 2016 Experimental dental resins composed of triethyleneglycol dimethacrylate, urethane dimethacrylate, ethoxylated bisphenol-A-dimethacrylate and bisphenol A glycidyl methacrylate containing an organoclay as filler were prepared by photopolymerization.

Behaviour of an organomontmorillonite-acetochlor formulation in drained wetland soils of the Hula Valley [PDF]
Mires and Peat, 2012 Weed control poses a real challenge to agriculture in general, and to agriculture on drained peatlands in particular. An understanding of the interactions between clay minerals and organic molecules has yielded effective preparations of herbicide ...

Remediation of Phenol-contaminated Aqueous Solutions by Synthesized Organoclay [PDF]
Iranica Journal of Energy and Environment, 2019 Phenol and its metabolites are among the hazardous organic compounds, due to their carcinogenicity, toxicity, long term persistence in the environment. The purposes of this study are the synthesis of organoclay as an adsorbent with high physicochemical ...
