The original structure of the nanosized sample shows a mixture of cubic and monoclinic structure. Our results show that the cubic and most of the monoclinic structure turns into hexagonal structure above 10.35GPa. But a small proportion of monoclinic structure can be present up to the highest pressure  36.2GPa. When the pressure is released  the hexagonal structure partly reverts to monoclinic structure  so the sample shows a mixture of hexagonal and monoclinic structure. The structural transition from monoclinic to hexagonal structure is reversible. IOP Publishing Ltd.
