... practice and the approach followed in the BritishStandard is in terms of the sample preparation method employed. In Britain samples are air-dried prior to wetting to a range of moisture contents and testing while in Sweden an initially wet sample is selectively air-dried to achieve the desired range...

...) a small deviation between measured water content and target water content. The low thawing efficiency of ice-bentonite mixtures can be solved by using a microwave-assisted thawing method. This research can improve the sample preparation method used to produce compacted buffer/backfill materials for HLW...

... in the low-temperature Mössbauer spectra. The Mössbauer parameters observed were close to those of Fe oxyhydroxides, suggesting the presence of some kind of nanoparticles. These results show that the treatment with acetonic FeCl 3 solution is an effective method for introducing Fe into montmorillonite...

... the differences and similarities in the structure and reactivity of the pyrite surface resulting from each preparation method under similar experimental conditions. A comparison will determine the extent to which results and conclusions presented in such types of studies, which have used different pyrite...

... the samples. The different treatments of the bentonite samples may lead to different structural features. Clear differences between low-density samples prepared using different procedures were observed. The influence of the preparation methods was less, but still noticeable, for the high-density samples...

..., 1) were prepared by precipitation method using FeCl 3 ·6H 2 O, FeCl 2 ·4H 2 O, and NiCl 2 ·6H 2 O as precursors. The performed analyses show the dependence of the rate of formation of the spinel phase on the chemical composition. To obtain the exact conditions for a single-phase spinel material...

... of cyclical steaming and (steam) soaking proved to be highly effective in softening the sediment sample enough so that it could be cored for AMS-sample preparation. Using this new method, samples were prepared in about 90% less time and for only 10% of the cost of standard impregnation techniques. GeoRef...
