Licochalcone B | Amyloid-β Inhibitor | MedChemExpress
Licochalcone B is an extract from the root of Glycyrrhiza inflate. Licochalcone B inhibits amyloid β (Aβ42) self-aggregation (IC50=2.16 μM) and disaggregate pre-formed Aβ42 fibrils, reduce metal-induced Aβ42 aggregation through chelating metal ions. - Mechanism
Aluminum in drinking water: Guideline technical …
The achievable residual aluminum concentration is also noted (e.g., <0.03 mg/L at temperatures <10 C and <0.05 mg/L at temperatures >10 C). Water utilities should thus aim to decrease total aluminum to <0.05 mg/L in filtered water (prior to fluoride or phosphorous addition) and further strive to achieve a target of <0.03 mg/L when temperatures are <10 °C (see Table 10).

Gypsum - Wikipedia
Gypsum is moderately water-soluble (~2.0–2.5 g/l at 25 C) and, in contrast to most other salts, it exhibits retrograde solubility, becoming less soluble at higher temperatures. When gypsum is heated in air it loses water and converts first to calcium sulfate hemihydrate, (bassanite, often simply called "plaster") and, if heated further, to anhydrous calcium sulfate (anhydrite).
