Energy surface and minimum energy paths for Fréedericksz transitions in bistable cholesteric liquid crystals.

Physical review. E

Ivanov AV, Bessarab PF, Aksenova EV, Romanov VP, Uzdin VM.
PMID: 27176367
Phys Rev E. 2016 Apr;93:042708. doi: 10.1103/PhysRevE.93.042708. Epub 2016 Apr 27.

The multidimensional energy surface of a cholesteric liquid crystal in a planar cell is investigated as a function of spherical coordinates determining the director orientation. Minima on the energy surface correspond to the stable states with particular director distribution....

Friedel-Crafts Alkylation of Arenes with 2-Halogeno-2-CF3-styrenes under Superacidic Conditions. Access to Trifluoromethylated Ethanes and Ethenes.

The Journal of organic chemistry

Sandzhieva MA, Kazakova AN, Boyarskaya IA, Ivanov AY, Nenajdenko VG, Vasilyev AV.

J Org Chem. 2016 Jun 17;81(12):5032-45. doi: 10.1021/acs.joc.6b00419. Epub 2016 Jun 09.

The formation of the corresponding benzyl cations [ArHC(+)-CH(X)CF3] takes place under protonation of E-/Z-2-halogeno-2-CF3 styrenes [ArCH═C(X)CF3, X = F, Cl, Br] in superacids. The structures of these new electrophiles were studied by means of NMR and theoretical DFT calculations....

Trefoil-Shaped Outer-Sphere Ion Clusters Mediate Lanthanide(III) Ion Transport with Diglycolamide Ligands.

Journal of the American Chemical Society

Brigham DM, Ivanov AS, Moyer BA, Delmau LH, Bryantsev VS, Ellis RJ.
PMID: 29083173
J Am Chem Soc. 2017 Dec 06;139(48):17350-17358. doi: 10.1021/jacs.7b07318. Epub 2017 Nov 14.

Outer-sphere ion clusters are inferred in many important natural and technological processes, but their mechanisms of assembly and solution structures are difficult to define. Here, we characterize trefoil-shaped outer-sphere lanthanide chloride and nitrate ion clusters in hydrocarbon solutions formed...

Gravity resonance spectroscopy constrains dark energy and dark matter scenarios.

Physical review letters

We report on precision resonance spectroscopy measurements of quantum states of ultracold neutrons confined above the surface of a horizontal mirror by the gravity potential of Earth. Resonant transitions between several of the lowest quantum states are observed for...

Influence of dipolar interactions on the magnetic susceptibility spectra of ferrofluids.

Physical review. E

Sindt JO, Camp PJ, Kantorovich SS, Elfimova EA, Ivanov AO.
PMID: 27415368
Phys Rev E. 2016 Jun;93(6):063117. doi: 10.1103/PhysRevE.93.063117. Epub 2016 Jun 24.

The frequency-dependent magnetic susceptibility of a ferrofluid is calculated under the assumption that the constituent particles undergo Brownian relaxation only. Brownian-dynamics simulations are carried out in order to test the predictions of a recent theory [A. O. Ivanov, V....

The effects of polydispersity on the initial susceptibilities of ferrofluids.

Journal of physics. Condensed matter : an Institute of Physics journal

Camp PJ, Elfimova EA, Ivanov AO.
PMID: 25327692
J Phys Condens Matter. 2014 Nov 12;26(45):456002. doi: 10.1088/0953-8984/26/45/456002. Epub 2014 Oct 20.

The effects of particle-size polydispersity on the initial susceptibilities of concentrated ferrofluids are analyzed using a combination of theory and computer simulation. The study is focused on a model ferrofluid with a prescribed magnetic-core diameter distribution, a fixed non-magnetic...

Granulin, a novel STAT3-interacting protein, enhances STAT3 transcriptional function and correlates with poorer prognosis in breast cancer.

Yeh JE, Kreimer S, Walker SR, Emori MM, Krystal H, Richardson A, Ivanov AR, Frank DA.
PMID: 26000098
Genes Cancer. 2015 Mar;6(3):153-68. doi: 10.18632/genesandcancer.58.

Since the neoplastic phenotype of a cell is largely driven by aberrant gene expression patterns, increasing attention has been focused on transcription factors that regulate critical mediators of tumorigenesis such as signal transducer and activator of transcription 3 (STAT3)....

In the current work, we performed a systematic study of the CxHxP4-x (x = 0-4) series using an unbiased CK global minimum and low-lying isomers search for the singlet and triplet P4-C4H4 species at the B3LYP/6-31G** level of theory....

Martian meteorite launch: high-speed ejecta from small craters.
