(author)During valve formation of the siliceous frustules of diatoms, bulk uptake of silicic acid and its subsequent transport through the cell is required before it can be deposited in the silica deposition vesicle (SDV). It has been assumed that transport takes place via silicon transporters (SITs), but if that were the case a control mechanism would...journal article 2010

(author)No-carrier added 31Si was produced by 31P(n,p)31Si in the nuclear reactor of the Delft University of Technology. Several methods were investigated to remove the side product 32P, and the chemical form of 31Si was investigated. All methods except one gave good results. Anion exchange with Dowex resin gave the best results in activity...journal article 2010
