Elemental dissolution of basalts with ultra-pure water at 340°C and 40 MPa in a newly developed flow-type hydrothermal apparatus
hydrothermal system water–basalt reaction elemental dissolution flow-type experiment sub-terrestrial microbial ecosystem
2017/4/11
To simulate the discharge zone of hydrothermal systems in the laboratory, we developed a flow-type hydrothermal
apparatus that can reproduce water–rock reactions at elevated temperatures and pressure...
Synthesis of Pure Zeolite X from Palygorskite Clay Using a Two-Stage Method
Palygorskite Clay Synthesis Two-Stage Method Zeolite X
2011/11/14
A natural mineral, palygorskite clay, was used to synthesize pure zeolite X via a two-stage method. The synthetic parameters, such as calcination, crystallization time, and SiO2/Al2O3 molar ratio, wer...
Reduction of Structural Fe(III) in Smectite by a Pure Culture of Shewanella Putrefaciens Strain MR-1
Clay Fe(III) reduction Metal-reducing bacteria Sediments Smectite Soils
2011/12/27
Abstract: Shewanella putrefaciens is a species of metal-reducing bacteria with a versatile respiratory metabolism. This study reports that S. putrefaciens strain MR-1 rapidly reduces Fe(III) within sm...
Retention of Cobalt by Pure and Foreign-Element Associated Goethites
Al-goethite Cd-goethite Co-extraction Co-sorption Cu-goethite Micropore diffusion Si-goethite
2011/12/27
Retention studies of the cobalt-goethite system were carried out using synthetic, star-shaped and lath-shaped pure, Al-, Cd-, Cu- and Si-associated goethites. Aluminium and Si are commonly occurring f...
A New Method of Dehydration for Pure Clay Materials using Peldri II
Critical point drying Freeze drying Mercury porosimetry Montmorillonite Peldri II SEM TEM
2011/12/30
A new chemical, Peldri II, is evaluated as a compound for drying soft clay materials. Peldri II, a fluorocarbon (1,1-difluorotetrachloroethane), is a solid at room temperature and is a liquid above 25...
Formation of Phyllosilicates and Zeolites from Pure Silica-Alumina Gels
Phyllosilicates Zeolites Pure Silica-Alumina Gels
2012/2/13
The hydrothermal aging of pure silica—alumina gels in presence of 10 ml of 0.1 N sodium hydroxide solution at 175, 150 and 130°C for 8–30 days led to the synthesis of zeolites and the phyllosilicates,...
