This paper tests the development of a silica fume-based material, capable to be used as a solid activator for the one-part geopolymerization of fly ash. Through a simple procedure, a mixture of silica fume, an amorphous and silicon-rich by-product, sodium hydroxide and water, is converted, after a low-temperature treatment, to a new powder product mainly containing sodium silicate (NaSiO). Two different treatment methods are tested for the synthesis of the solid activator: heat and microwave treatment.

The aim of this study was to investigate the effects of starch and natural filler resistant starch type 2 (RS2) particles concentration on the textural properties of corn starch hydrogels. Native starch (NS) hydrogels of 8%, 10%, 12%, and 15% w/v were prepared; in each of these dispersions, part of the NS was substituted with RS2 to a concentration of 2% or 10%.

Article Synopsis
- Scientists made a special compound called β-cyclodextrin with iodine and cobalt, and studied it using a method called FT-Raman spectroscopy at different temperatures.
- They found that there are two types of iodine units: one type doesn't interact with cobalt ions, while the other type does.
- The research showed that the shape and behavior of these iodine units change when heated, especially one type that becomes more organized at higher temperatures.
