PMID: 28945410
Acc Chem Res. 2017 Mar 21;50(3):573-576. doi: 10.1021/acs.accounts.6b00560.

Materials are central to our way of life and future. Energy and materials as resources are connected, and the obvious connections between them are the energy cost of materials and the materials cost of energy. For both of these,...

On the origin of the lattice constant anomaly in nanocrystalline ceria.

Physical chemistry chemical physics : PCCP

Kossoy A, Feldman Y, Wachtel E, Gartsman K, Lubomirsky I, Fleig J, Maier J.
PMID: 16633592
Phys Chem Chem Phys. 2006 Mar 07;8(9):1111-5. doi: 10.1039/b513764k. Epub 2006 Jan 30.

The lattice parameter of nanocrystalline ceria films prepared by sputtering was monitored as a function of annealing temperature. Within the temperature range of 150-420 degrees C, an equilibrium with atmospheric oxygen is established within a few hours, whereas grain...

Origin of polarity in amorphous SrTiO3.

Physical review letters

Frenkel AI, Ehre D, Lyahovitskaya V, Kanner L, Wachtel E, Lubomirsky I.
PMID: 18233225
Phys Rev Lett. 2007 Nov 23;99(21):215502. doi: 10.1103/PhysRevLett.99.215502. Epub 2007 Nov 20.

Although neither SrTiO3 nor BaZrO3 has any polar crystalline polymorphs, they may form noncrystalline pyro- and piezoelectric phases [Adv. Mater. 19, 1515 (2007)10.1002/adma.200602149]. These phases and the similar phase of BaTiO3 have been called quasiamorphous. In this Letter, the...

The role played by oxygen plasma on Teflon: relevance to the concept of "cryptoelectrons".

Physical chemistry chemical physics : PCCP

Piperno S, Cohen H, Bendikov T, Lahav M, Lubomirsky I.
PMID: 22739684
Phys Chem Chem Phys. 2012 Aug 21;14(31):11185-6. doi: 10.1039/c2cp41505d. Epub 2012 Jun 28.

Dr Williams (AIP Adv., 2012, 2, 010701) suggested that cleaning Teflon by high pressure oxygen plasma may have affected our result that Cu(2+) and Pd(2+) ions can be absorbed but not chemically reduced by a Teflon surface rubbed by...

Solvent-Induced Crystal Polymorphism as Studied by Pyroelectric Measurements and Impedance Spectroscopy: Alcohols as Tailor-Made Inhibitors of α-Glycine.

Angewandte Chemie (International ed. in English)

Meirzadeh E, Dishon S, Weissbuch I, Ehre D, Lahav M, Lubomirsky I.
PMID: 29405549
Angew Chem Int Ed Engl. 2018 Apr 23;57(18):4965-4969. doi: 10.1002/anie.201800741. Epub 2018 Mar 15.

Metastable polymorphs commonly emerge when the formation of the stable analogues is inhibited by using different solvents or auxiliaries. Herein, we report that when glycine is grown in aqueous solutions in the presence of low concentrations of different co-solvents,...

How to interpret current-voltage relationships of blocking grain boundaries in oxygen ionic conductors.

Physical chemistry chemical physics : PCCP

Kim SK, Khodorov S, Chen CT, Kim S, Lubomirsky I.
PMID: 23640401
Phys Chem Chem Phys. 2013 Jun 14;15(22):8716-21. doi: 10.1039/c3cp00145h. Epub 2013 May 02.

A new model based on a linear diffusion equation is proposed to explain the current-voltage characteristics of blocking grain boundaries in Y-doped CeO2 in particular. One can also expect that the model can be applicable to the ionic conductors...

Anelastic and Electromechanical Properties of Doped and Reduced Ceria.

Advanced materials (Deerfield Beach, Fla.)

Wachtel E, Frenkel AI, Lubomirsky I.

Room-temperature mechanical properties of thin films and ceramics of doped and undoped ceria are reviewed with an emphasis on the anelastic behavior of the material. Notably, the unrelaxed Young's modulus of Gd-doped ceria ceramics measured by ultrasonic pulse-echo techniques...

Van Vleck paramagnetism in undoped and Lu-doped bulk ceria.

Physical chemistry chemical physics : PCCP

Varenik M, Zhang XD, Leitus G, Yavo N, Carmieli R, Wachtel E, Guo X, Lubomirsky I.

The magnetic properties of undoped, bulk CeO2 are not fully understood. In contrast to nanocrystalline ceria that exhibits paramagnetism attributed to Ce3+ at grain surfaces, bulk ceria is weakly paramagnetic, despite the absence of magnetic ions. In the present...

Comparative analysis of XANES and EXAFS for local structural characterization of disordered metal oxides.

In functional materials, the local environment around active species that may contain just a few nearest-neighboring atomic shells often changes in response to external conditions. Strong disorder in the local environment poses a challenge to commonly used extended X-ray...
