It is found that polar and nonpolar orders of CH3NH3PbI3 can be distinguished from their distinct lateral piezoresponse, energy dissipation, first and second harmonic electromechanical couplings, and temperature variation, even though their difference in crystalline lattice is very subtle, and they ...

Nevertheless, the exact atomic structure of OIHPs is still unsettled, with two possible space groups, polar I4cm and nonpolar I4/mcm still hotly debated depending on the orienta- tions of polar ions such as MA+ 14. While many perovskite oxides are polar with strong ferroelectricity, the ...

thin films can also be obtained using a one-step solution process with an in situ nonpolar antisolvent washing treatment [3,4,9]. Toluene, chlorobenzene, boromobenzene, and iodobenzene have been used as the anti-solvent in the washing treatment process while a mixture of gamma-butyrolactone (...
For receptors, the preparation consisted of the elimination of ligands and ions co-crystallized, the addition of polar hydrogens, and the assignment of Kollman charges. In some receptors its main cofactors were conserved in their binding sites, i.e., the P450 heme in CYP51 and the Guanosine...
