Centrosymmetry Breaking and Ferroelectricity Driven by Short-Range Magnetic Order in the Quadruple Perovskite (YMn(3))Mn(4)O(12).
Verseils M, Mezzadri F, Delmonte D, Cabassi R, Baptiste B, Klein Y, Calestani G, Bolzoni F, Gilioli E, Gauzzi A. Verseils M, et al. Inorg Chem. 2019 Oct 21;58(20):14204-14211. doi: 10.1021/acs.inorgchem.9b02298. Epub 2019 Oct 8. Inorg Chem. 2019. PMID: 31593448
By means of single-crystal X-ray diffraction, we give direct crystallographic evidence of a centrosymmetry breaking below T(S) = 200 K, concomitant with the onset of a commensurate structural modulation in the quadruple perovskite YMn(3)Mn(4)O(12). ...

New Twists of 3D Chiral Metamaterials.
Fernandez-Corbaton I, Rockstuhl C, Ziemke P, Gumbsch P, Albiez A, Schwaiger R, Frenzel T, Kadic M, Wegener M. Fernandez-Corbaton I, et al. Adv Mater. 2019 Jun;31(26):e1807742. doi: 10.1002/adma.201807742. Epub 2019 Feb 21. Adv Mater. 2019. PMID: 30790363 Review.
This statement is especially true for chiral metamaterials, as unlocking certain degrees of freedom necessarily requires broken centrosymmetry. While the field of chiral electromagnetic/optical metamaterials has become rather mature, the field of elastic/mechanical metamat …

Peculiar piezoelectricity of atomically thin planar structures.
Ghasemian MB , Daeneke T , Shahrbabaki Z , Yang J , Kalantar-Zadeh K . Ghasemian MB , et al. Nanoscale. 2020 Feb 6;12(5):2875-2901. doi: 10.1039/c9nr08063e. Nanoscale. 2020. PMID: 31984979 Review.
The origin of the enhanced piezoelectricity in such thin planes is attributed to the loss of centrosymmetry, altered carrier concentration, and change in local polarization and can be efficiently tailored via surface modifications. ...

Modeling of supramolecular centrosymmetry effect on sarcomeric SHG intensity pattern of skeletal muscles.
Rouède D, Recher G, Bellanger JJ, Lavault MT, Schaub E, Tiaho F. Rouède D, et al. Biophys J. 2011 Jul 20;101(2):494-503. doi: 10.1016/j.bpj.2011.05.065. Biophys J. 2011. PMID: 21767503 Free PMC article.
During proteolysis, experimental sarcomeric SHG intensity pattern exhibits decrease on intensity at the center of the sarcomere. An effective intra- and interthick filaments centrosymmetry of 320 25 nm, in agreement with ultrastructural disorganization observed at the elec …

Reactive oxygen species for therapeutic application: Role of piezoelectric materials.
Sengupta D, Naskar S, Mandal D. Sengupta D, et al. Phys Chem Chem Phys. 2023 Oct 4;25(38):25925-25941. doi: 10.1039/d3cp01711g. Phys Chem Chem Phys. 2023. PMID: 37727027 Review.
Among the various influencers, herein, piezoelectric materials driven ROS generation activity is primarily considered. Intrinsic non-centrosymmetry of piezoelectric materials makes them suitable for distinct dipole formation in the presence of external mechanical stimuli. …

Non-volatile electric-field control of inversion symmetry.
Caretta L, Shao YT, Yu J, Mei AB, Grosso BF, Dai C, Behera P, Lee D, McCarter M, Parsonnet E, K P H, Xue F, Guo X, Barnard ES, Ganschow S, Hong Z, Raja A, Martin LW, Chen LQ, Fiebig M, Lai K, Spaldin NA, Muller DA, Schlom DG, Ramesh R. Caretta L, et al. Nat Mater. 2023 Feb;22(2):207-215. doi: 10.1038/s41563-022-01412-0. Epub 2022 Dec 19. Nat Mater. 2023. PMID: 36536139
Application of orthogonal in-plane electric (polar) fields results in reversible non-volatile interconversion between the two phases, hence removing and introducing centrosymmetry. Counterintuitively, we find that an electric field 'erases' polarization, resulting from the …
