A PIV and CFD analysis of natural convection ice melting [PDF]

open access: yes, 2001
The melting of a vertical ice cylinder in water is investigated in this paper. The experiments were carried out in a water-filled cylindrical Perspex barrel with adiabatic walls for Rayleigh numbers of 0.22x108 and 0.475x108. The ice crystal is suspended

Onset of solid-state mantle convection and mixing during magma ocean solidification [PDF]

open access: yes, 2016
©2017. American Geophysical UnionThe energy sources involved in the early stages of the formation of terrestrial bodies can induce partial or even complete melting of the mantle, leading to the emergence of magma oceans. The fractional crystallization of

Eggshell‐Based Biochar for Superior Adsorption of Crystal Violet Dye and Fluoride From Wastewater

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Present study investigates the efficiency of eggshell biochar as a low‐cost and ecofriendly adsorbent for the simultaneous removal of fluoride ions and crystal violet (CV) dye from wastewater. The eggshell waste was pyrolyzed to produce biochar, which was thoroughly characterized and subsequently employed for contaminant adsorption.

The Creation and Evolution of Crystal Mush in the Upper Zone of the Rustenburg Layered Suite, Bushveld Complex, South Africa

open access: yesJournal of Petrology, 2019
The Upper Zone of the Rustenburg Layered Suite of the Bushveld Complex contains the world’s largest Fe–Ti–V ± P deposit and formed from the last major injection of magma into the chamber.

Flow-to-fracture transition in a volcanic mush plug may govern normal eruptions at Stromboli [PDF]

open access: yes, 2016
Stromboli is a model volcano for studying eruptions driven by degassing. The current paradigm posits that Strombolian eruptions represent the bursting of gas slugs ascending through melt‐filled conduits, but petrological observations show that magma at ...

Polyethylene–Cellulose Composites From Cellulose Xanthate Solutions

open access: yesJournal of Applied Polymer Science, EarlyView.
An approach for fabricating cellulose/LDPE composites through cellulose dissolution, LDPE dispersion, and subsequent hot‐pressing. ABSTRACT This study reports a processing route for fabricating cellulose/LDPE composites involving the dispersion of polyethylene powder in a cellulose solution, followed by regeneration to form a continuous cellulose ...

Mesozoic magmatism and granitic dome in the Wugongshan Massif, Jiangxi province and their genetical relationship to the tectonic events in southeast China [PDF]

open access: yes, 2001
In SE China, a Mesozoic granitic dome coeval to extensional tectonics is exposed in the Wugongshan massif. Its center is occupied by Mesozoic granitoids and granitic gneisses, and the E–W-trending Late-Paleozoic–Mesozoic Pingxiang and Anfu basins are ...

Improving Oxygen Barrier Performance of Polylactide Film by Using Bleached and Unbleached Nanocellulose From Grape Pomace

open access: yesJournal of Applied Polymer Science, EarlyView.
Bleached and unbleached nanocelluloses were produced from the exhausted grape pomace and applied as coatings on PLA substrates for sustainable food packaging. Unbleached nanocelluloses were more hydrophobic and amorphous than bleached ones. The resulting bio‐based bleached nanocellulose‐coated PLA films showed a 68% reduction in O2 permeability ...

Microstructural evidence for crystallization regimes in mafic intrusions: a case study from the Little Minch Sill Complex, Scotland [PDF]

open access: yes
The magma forming the 20 m thick crinanitic/picrodoleritic Dun Raisburgh sill, part of the Little Minch Sill Complex of NW Scotland, comprised a mafic carrier liquid with a crystal cargo of plagioclase and olivine (1 vol%).

Textural and chemical consequences of interaction between hydrous mafic and felsic magmas:an experimental study [PDF]

open access: yes, 2016
Mantle-derived, hydrous mafic magmas are often invoked as a mechanism to transfer heat, mass and volatiles to felsic plutons in the Earth’s crust. Field observations suggest that mafic, water-rich magmas often intrude viscous felsic crystal-rich mushes ...
