Electronic and Structural Properties of ABO3: Role of the B-O Coulomb Repulsions for Ferroelectricity.

Materials (Basel, Switzerland)

Miura K, Azuma M, Funakubo H.
PMID: 28879987
Materials (Basel). 2011 Jan 17;4(1):260-273. doi: 10.3390/ma4010260.

We have investigated the role of the Ti-O Coulomb repulsions in the appearance of the ferroelectric state in BaTiO3 as well as the role of the Zn-O Coulomb repulsions in BiZn0.5Ti0.5O3, using a first-principles calculation with optimized structures. In...

A metal to insulator transition in integer or half integer charge systems can be regarded as crystallization of charges. The insulating state tends to have a glassy nature when randomness or geometrical frustration exists. We report that the charge...

A Theoretical Investigation on CO Oxidation by Single-Atom Catalysts M.

ChemCatChem. 2017 Apr 07;9(7):1222-1229. doi: 10.1002/cctc.201601713. Epub 2017 Mar 16.

Single-atom catalysts have attracted much interest recently because of their excellent stability, high catalytic activity, and remarkable atom efficiency. Inspired by the recent experimental discovery of a highly efficient single-atom catalyst Pd

Observation of Magnetoelectric Multiferroicity in a Cubic Perovskite System: LaMn(3)Cr(4)O(12).

Physical review letters

Wang X, Chai Y, Zhou L, Cao H, Cruz CD, Yang J, Dai J, Yin Y, Yuan Z, Zhang S, Yu R, Azuma M, Shimakawa Y, Zhang H, Dong S, Sun Y, Jin C, Long Y.
PMID: 26340207
Phys Rev Lett. 2015 Aug 21;115(8):087601. doi: 10.1103/PhysRevLett.115.087601. Epub 2015 Aug 18.

Magnetoelectric multiferroicity is not expected to occur in a cubic perovskite system because of the high structural symmetry. By versatile measurements in magnetization, dielectric constant, electric polarization, neutron and x-ray diffraction, Raman scattering, as well as theoretical calculations, we...

Sexual Dimorphism in the Response of Mercurialis annua to Stress.

Metabolites

Orlofsky EM, Kozhoridze G, Lyubenova L, Ostrozhenkova E, Winkler JB, Schröder P, Bacher A, Eisenreich W, Guy M, Golan-Goldhirsh A.
PMID: 27128954
Metabolites. 2016 Apr 26;6(2). doi: 10.3390/metabo6020013.

The research presented stemmed from the observations that female plants of the annual dioecious Mercurialis annua outlive male plants. This led to the hypothesis that female plants of M. annua would be more tolerant to stress than male plants....

Modeling Molecular Systems at Extreme Pressure by an Extension of the Polarizable Continuum Model (PCM) Based on the Symmetry-Adapted Cluster-Configuration Interaction (SAC-CI) Method: Confined Electronic Excited States of Furan as a Test Case.

Journal of chemical theory and computation

Fukuda R, Ehara M, Cammi R.
PMID: 26574410
J Chem Theory Comput. 2015 May 12;11(5):2063-76. doi: 10.1021/ct5011517. Epub 2015 Apr 28.

Novel molecular photochemistry can be developed by combining high pressure and laser irradiation. For studying such high-pressure effects on the confined electronic ground and excited states, we extend the PCM (polarizable continuum model) SAC (symmetry-adapted cluster) and SAC-CI (SAC-configuration...

The TNM pN stage based on the number of metastatic lymph nodes is an independent prognostic factor in gastric cancer. Many studies have highlighted the phenomenon of stage migration and problems in comparing groups of patients with different numbers...

Notch Signaling and Maintenance of SOX2 Expression in Rat Anterior Pituitary Cells.

Acta histochemica et cytochemica

After publication of reports describing the presence of stem/progenitor cells among non-hormone-producing cells in the pituitary, the mechanism responsible for proliferation and differentiation generated considerable interest. Several studies have suggested that Notch signaling is involved. In the present study,...

Magnetoelectric multiferroics have received much attention in the past decade due to their interesting physics and promising multifunctional performance. For practical applications, simultaneous large ferroelectric polarization and strong magnetoelectric coupling are preferred. However, these two properties have not been...
