EXPERIMENTS ON THE USE OF SILICIC ACID FOR STEROID CHROMATOGRAPHY

, 1956
Mixtures of pure sterols, and extracts of hydrolyzed urine, were chromatographed on columns of silicic acid. The results were observed spectrometrically using a sulphuric acid – methanol color reagent.

The influence of foliar applied silicic acid on N, P, K, Ca and Mg concentrations in field peas^*

Journal für Kulturpflanzen, 2016
Silicon (Si) is the second most abundant element after oxygen in soil. However, many field studies have shown that supplying crops with extra Si in form of finely dispersed SiO2 · n H2O (= silicic acid “dissolved” in water) suppresses plant disease ...

Silicic acid HPLC of cardiolipin, mono- and dilysocardiolipin, and several of their chemical derivatives.

Journal of Lipid Research, 1990
A silicic acid HPLC system in hexane-2-propanol-1 mM H3PO4 50:50:3.5 (v/v/v) is described for the analysis and/or purification of cardiolipin (CL), monolysocardiolipin (MLCL), dilysocardiolipin (DLCL), and several of their chemical derivatives ...

Effect of silicic acid gel on the determination of pH [PDF]

, 1934
The general purpose of this investigation, as well as many other investigations made on silicic acid gels at Union College, has been to obtain data which may help to formulate an idea of the gel structure and the process of setting of silicic acid gels ...

Silicon induces positive responses at the biochemical and gene expression levels in tomato plants inoculated with Fusarium oxysporum

Polibotánica
Tomato plants infested by Fusarium oxysporum (Fol) show limitations in yield and fruit quality. The application of silicic acid could be used as an alternative to mitigate damage caused by this pathogen.

Dialysis of silicic acid gels [PDF]

, 1947
The primary purpose of this investigation was to prove or disprove the existence of an equilibrium between polysilicic acid molecules and simple silicic acid molecules in a set silicic acid gel.

Composition of cabbage leaf phospholipids*

Journal of Lipid Research, 1960
An attempt has been made to resolve the phospholipids of cabbage leaf by chromatography on silicic acid. The components include phosphatidylglycerol and an unknown glycerolphospholipid.
