On a tropical island, fossils reveal the past – and possible future – of polar ice
On a tropical island, fossils reveal the past possible future polar ice
2015/1/20
The balmy islands of Seychelles couldn’t feel farther from Antarctica, but their fossil corals could reveal much about the fate of polar ice sheets.About 125,000 years ago, the average global temperat...
Diurnal variations of polar organic tracers in summer forest aerosols: A case study of a Quercus and Picea mixed forest in Hokkaido, Japan
secondary organic aerosol isoprene 2-methyltetrols levoglucosan

We investigated the summertime formation of secondary organic aerosols (SOA) via the oxidation of isoprene, α/β-
pinene and β-caryophyllene in a Quercus crispula and Picea glehnii mast mixed forest l...
Swelling of Formamide-Montmorillonite Complexes in Polar Liquids
Donor Number Formamide Montmorillonite Osmotic Swelling Polar Liquids Swelling
2011/12/7
Abstract: A new osmotic-swelling system for montmorillonite with formamide (FA) is described. Water and a variety of polar organic liquids were used to swell FA-montmorillonite complexes. The post-swe...
Some Evidence Supporting the Existence of Polar Layers in Mixed-Layer Illite/Smectite
Differential Thermal Analysis Mixed-layer illite/smectite Polar layer
2011/12/28
The fraction <20 祄 of a bentonitic material was selected to study the transformation of smectite into illite under hydrothermal conditions. Powder XRD showed that the studied material was composed of ...
Calculation of Electrostatic Interlayer Bonding Energy and Lattice Energy of Polar Phyllosilicates: Kaolinite and Chlorite
Chlorite Electrostatic energy Interlayer bonding Kaolinite Lattice energy
2012/2/6
The electrostatic lattice energy of polar phyllosilicates can be calculated when a correction term Ecorr equal to −2鸬2/V is taken into account, where ?is the dipole moment of a slice d(001) and ...
Swelling of Montmorillonite in Polar Organic Liquids
Swelling Montmorillonite Polar Organic Liquids
2012/2/15
The crystalline and osmotic swelling of Na-, Cs-, Mg- and Ca-montmorillonite has been measured in dimethyl sulphoxide and in formamide, N-methyl formamide, dimethyl formamide, N-methyl acetamide and d...
