In this work, we report novel flexible polyvinylidene fluoride (PVDF) hybrid pressure sensors with good mechanical properties. Hybrid combinations of reduced graphene oxide (rGO) with different nano metal oxides -titanium ...

Nanocrystalline materials, those with grain size <100 nm, were found to have superior mechanical properties compared to their coarse-grained (CG) counterparts. However, these materials are not thermally stable because of ...

Erbium ions (Er3+) doped in a solid material enables the intra 4f shell transitions from its first excited state (4I13/2) to the ground state (4I15/2). The intra-4f shell transition at 1540 nm is of exceptional interest ...
