Critical Thickness for Antiferroelectricity in PbZrO3.

Physical review letters

Mani BK, Chang CM, Lisenkov S, Ponomareva I.
PMID: 26371680
Phys Rev Lett. 2015 Aug 28;115(9):097601. doi: 10.1103/PhysRevLett.115.097601. Epub 2015 Aug 26.

Ferroelectrics and antiferroelectrics appear to have just the opposite behavior upon scaling down. Below a critical thickness of just a few nanometers the ferroelectric phase breaks into nanodomains that mimic electric properties of antiferroelectrics very closely. On the other...

Emergence of ferroelectricity in antiferroelectric nanostructures.

Mani BK, Herchig R, Glazkova E, Lisenkov S, Ponomareva I.
PMID: 27039877
Nanotechnology. 2016 May 13;27(19):195705. doi: 10.1088/0957-4484/27/19/195705. Epub 2016 Apr 04.

First-principles-based finite-temperature simulations are used to predict the emergence of ferroelectricity in antiferroelectric nanostructures made of PbZrO3. The phenomenon is expected to occur in antiferroelectric nanodots, nanowires, and thin films with good surface charge compensation and can be explained...

We report valence and conduction band densities of states measured via ultraviolet and inverse photoemission spectroscopies on three metal halide perovskites, specifically methylammonium lead iodide and bromide and cesium lead bromide (MAPbI3, MAPbBr3, CsPbBr3), grown at two different institutions...

Diode-Pumped Organo-Lead Halide Perovskite Lasing in a Metal-Clad Distributed Feedback Resonator.

Nano letters

Jia Y, Kerner RA, Grede AJ, Brigeman AN, Rand BP, Giebink NC.
PMID: 27331618
Nano Lett. 2016 Jul 13;16(7):4624-9. doi: 10.1021/acs.nanolett.6b01946. Epub 2016 Jun 24.

Organic-inorganic lead halide perovskite semiconductors have recently reignited the prospect of a tunable, solution-processed diode laser, which has the potential to impact a wide range of optoelectronic applications. Here, we demonstrate a metal-clad, second-order distributed feedback methylammonium lead iodide...

BACKGROUND: Addiction is a relapsing chronic condition in which psychiatric phenomena play a crucial role. Psychopathological symptoms in patients with heroin addiction are generally considered to be part of the drug addict's personality, or else to be related to...

Effect of conditioning and carcass posture on eating quality of mutton from old Bannur ewes.

Meat science

Dani NP, Mahendrakar NS, Rajalakshmi D, Dhanaraj S.
PMID: 22054987
Meat Sci. 1982 Jun;6(4):265-73. doi: 10.1016/0309-1740(82)90037-7.

Twenty-six mature ewes of an indigenous mutton breed, slaughtered and dressed conventionally, were used for the experiment described in this paper. The effect of three different conditioning temperatures and two methods of hanging posture on texture and palatability were...

Spectral element method and the delayed feedback control of chaos.

Physical review. E, Statistical, nonlinear, and soft matter physics

Tweten DJ, Mann BP.
PMID: 23214670
Phys Rev E Stat Nonlin Soft Matter Phys. 2012 Oct;86(4):046214. doi: 10.1103/PhysRevE.86.046214. Epub 2012 Oct 31.

A spectral element approach is introduced to determine the Floquet exponents (FEs) of unstable periodic orbits (UPOs) stabilized by extended delayed feedback control (EDFC). The spectral approach does not require solving time-dependent eigenproblems that existing methods require. Instead, the...

PMID: 22958592
Arch Public Health. 2012 Mar 16;70(1):4. doi: 10.1186/0778-7367-70-4.

BACKGROUND: In malaria endemic areas, fever has been used as an entry point for presumptive treatment of malaria. At present, the decrease in malaria transmission in Africa implies an increase in febrile illnesses related to other causes among underfives....
