The aqueous synthesis method to prepare large cage mesoporous silica with cubic Fm3m structure is based on the use of EO106PO70EO106 triblock copolymer (F127) at low HCl concentrations, with no additional salts or organic additives. Here, emphasis is put on the low HCl concentration regime, ...
According to the results of electron diffraction reported in the literature this carbon allotrope has a space group Fm \(\bar{3}\) m (group number 225) with a lattice parameter of about 3.54–3.57 Å. Nevertheless, because of the closeness of its lattice parameter to that of diamond...

The composition was determined as Hg[sub 2]Re[sub 0.5]Ba[sub 4]Ca[sub 1.5]O[sub 8.5] and an univocal interpretation was found in terms of the high-symmetry space group Fm3m(225), with Z=2, (=6.70 g/cm鲁; the reliability factor was 5.0%. This phase, Cu-free and not ...
