Doping ferroelectrics with carriers is often detrimental to polarization. This makes the design and discovery of metals that undergo a ferroelectric-like transition challenging. In this letter, we show from first principles oxygen octahedral rotations in perovskites are enhanced by electron doping, can be used as means strengthen structural polarization certain hybrid-improper -- compounds whic...

In order to understand the mechanisms involved in the extraction processes developed to separate minor actinides, the “ligand/metallic cation” complexes formed in the organic phases are characterized by electrospray ionization-mass-spectrometry (ESI-MS). This paper deals with the application of the ESI-MS technique to analyze americium complexes in organic solutions. Two extractant systems are ...

-The ESR spin probe, TEMPAMINE +, was used to study the interlamellar behavior of adsorbed organic cations on hectorites solvated with water, ethanol, and water-ethanol mixtures, and saturated with several monovalent and divalent metallic cations. The mobility and orientation of the probe was affected greatly by the solvent, and to a lesser extent by the predominant exchangeable cation on the s...

The electronic polarization energies, P 1⁄4 Pþ þ P , of a perylenetetracarboxylic acid dianhydride (PTCDA) cation and anion in a crystalline thin film on a metallic substrate are computed and compared with measurements of the PTCDA transport gap on gold and silver. Both experiments and theory show that P is 500 meV larger in a PTCDA monolayer than in 50 A films. Electronic polarization in syste...

By oxidation of P-keto acids, cyclopropanols, and acyl chromate complexes with tris(2-pyridinecarboxylato)manganese(III) (Mn(pic)g), a-keto, p-keto, and alkyl radicals are generated respectively, which react with olefinic compounds to afford intermolecular addition products in good yield. The cation radicals can be generated from a-stannylalkyl sulfides, (1 -stannylalkyl)amino compounds, and a-...

The metallic interface between insulating LaAlO3 and SrTiO3 opens up the field of oxide electronics. With more than a decade of researches on this heterostructure, the origin of the interfacial conductivity, however, remains unsettled. Here we resolve this long-standing puzzle by atomic-scale observation of electron-gas formation for screening hidden lattice instabilities, rejuvenated near the ...

Copper-succinate-layered hydroxide (CSLH), a new nanohybrid material, was synthesized as an inorganic-organic nanohybrid, in which organic moiety was intercalated between the layers of a single cation layered material, copper hydroxide nitrate. Microporous scaffold carbon material was obtained by thermal decomposition of the nanohybrid at 500 °C under argon atmosphere followed by acid washing p...

In a previous communication (1) it was shown that data obtained from transference experiments with alkali solutions of casein could be best interpreted on the assumption that the carriers of the current are alkali metal cations and casein anions. In the present studies on the transport numbers of solutions of casein with the alkali earth elements, the data appear to indicate that part of the me...
