In recent years, experimental demonstration of ferroelectric tunnel junctions (FTJ) based on perovskite tunnel barriers has been reported. However, integrating these perovskite materials into conventional silicon memory technology remains challenging due to their lack of compatibility with the complementary...

Changing fire regimes in response to climate change are likely to have significant effects on terrestrial ecosystems and biogeochemical cycles. While effects of fire on some nutrient cycles have been quite well-studied, little attention has been paid to the...

Extracting entanglement from identical particles.

Physical review letters

Killoran N, Cramer M, Plenio MB.
PMID: 24785015
Phys Rev Lett. 2014 Apr 18;112(15):150501. doi: 10.1103/PhysRevLett.112.150501. Epub 2014 Apr 15.

Identical particles and entanglement are both fundamental components of quantum mechanics. However, when identical particles are condensed in a single spatial mode, the standard notions of entanglement, based on clearly identifiable subsystems, break down. This has led many to...

A series of charged and neutral four-center n-electron (4c-ne, n = 1-4) molecules based on the adamantane framework, but which include combinations of boron, nitrogen, and phosphorus atoms at bridgehead positions, were studied computationally at the B3LYP/6-31G* level of...

Nematic liquid crystals with a tetrafluoroethylene bridge in the mesogenic core structure.

Journal of the American Chemical Society

Kirsch P, Bremer M, Huber F, Lannert H, Ruhl A, Lieb M, Wallmichrath T.
PMID: 11389620
J Am Chem Soc. 2001 Jun 13;123(23):5414-7. doi: 10.1021/ja010024l.

A dramatic increase of the clearing temperatures of liquid crystals based on bis(cyclohexyl)ethane 1 by 50 to 70 K can be achieved by the perfluorination of the central ethylene link. Conformational analysis indicates that this effect is due to...

Asymmetric top rotors in electric fields: influence of chaos and collisions in molecular beam deflection experiments.

From spectroscopic studies as well as from the stability constants of their complexes with metal ions, it has been observed that substituted N-hydroxyacetoacetanilides do not enolize, because of strong hydrogen bonding in the hydroxamic moiety CH(3).CO.CH(2).CO.N(OH).R hindering the movement...
