Clay materials useful as binding agents in green sandcasting and other molding processes are discussed, as well as methods of preparing such clay materials. The clay materials may be chemically treated. For example, a natural clay may be combined with one or more reducing agents, such that an...
Another study targeted the removal of crystal violet from water using a biosorbent prepared by the valorization of jujube shell wood (El Messaoudi et al.2017). The jujube core was initially crushed to extract the shell, which was then processed using procedures similar to those used for the bio...
New Method of Preparing Clay Samples for Differential Thermal Analysis A method of preparing clay samples for differential thermal analysis which permits the analysis to be made with the test and reference samples freely exposed to the furnace atmosphere is described. The data obtained when samples we...

In particular, the invention relates to methods and microorganisms are prevented and / or storage and / or generation of homolanthionine in the methionine pathway is reduc...
Preparation of polymer–clay nanocomposites and their properties An overview of the progress in polymer nanocomposites is presented in this paper with an emphasis on the different methods used for preparing polymer‐laye... Quang,T.,Nguyen,... - 《Advances in Polymer Technology》 被引量: 279发表...
3,892,655 to Hickson, which is incorporated herein by reference, describes a method of preparing a layer-type, trioctahedral, clay-like material. The layer-type material is prepared by hydrothermal crystallization from aqueous slurries of a mixture of hydrous silica, hydrous alumina, hydrous ...
The method involved preparing a solution of methacryloyloxyethyl phosphorylcholine monomer. Polylactic acid nanofibre mats were then immersed in this solution and exposed to ultraviolet light radiation. The results showed that the addition of poly(methacryloyloxyethyl phosphorylcholine improved the solubility of...
The new advance in the preparation of polymers/nano-clay by intercalation methods is summaried. According to different intercalation mechanism and intercalation ways , the intercalation methods are majorly classified into two categories, solution intercalation and melt intercalation. The new preparing method...
Some advances in measurement techniques, methods of preparing, installing and saturating specimens, and the measurement of the initial effective stress are discussed, with particular emphasis on potential sources of disturbance and methods to reduce this. The use of unconsolidated undrained tests and ...
Methods for preparing soil suspensions for counting Azotobacter chroococcum in vertisols by soil dilution and plating were investigated. Mechanical methods to promote disaggregation of soil and Azotobacter microcolonies by shaking soil suspensions with glass beads (10% w/v) or coarse sand (1-2 mm fra...
