After PS cores were dissolved in solvent, hollow TiO2 PANI spheres formed, which could be further calcined to produce mesoporous hollow TiO2 spheres.
The silica and silicon discoid cores were dissolved in an 8% aqueous solution of hydrofluoric acid and in HF/NHO3, 3 1 v/v, respectively, followed by dialysis in aqueous solution at pH = 4 using Float-A-lyzer tubes (Spectrum Laboratories) with an MWCO of 20 000 g mol 1 for 2 days.
Once the nanocrystals in the core are dissolved completely, a hollow cavity structure would form.
First, the prism sheath area and then the prism core are dissolved, leaving the well-known honey comb appearance [ 74].
Further the poly methyl methacrylate) core was dissolved, leading to a tubular structure.
Hollow PdPt nanocages were prepared by applying potential cycling treatment on core shell Pd@Pt nanodendrites in 0.5 M sulfuric acid aqueous solutions, during which Pd core was dissolved and the Pd@Pt structure was transformed to hollow nanocages.
The weighted composite core was dissolved in 20 ml of 1.0 M HCl solution and sonicated over 2 h in an ultrasonic bath, then mixed with aniline HCl solution by magnetic stirrer.
Therefore, the Au core was dissolved using 1 mM KI and a BCA assay was performed to quantify the amount of HK2 bound to 3-BP.
New calculations suggest that Jupiter's icy, rocky core is dissolving twice as fast as scientists previously predicted, New Scientist reports.
That means the solid rock in Jupiter's core is dissolving into liquid, as the researchers report in a paper submitted to Physical Review Letters, although the exact rate of erosion is unknown.
