Wheat grain hardness is a major factor in the wheat end-product quality. Grain hardness in wheat affects such parameters as milling yield, starch damage and baking properties. A single locus determines whether wheat is hard or soft textured. This...

A pyrrolo-tetrathiafulvalene cage: synthesis and X-ray crystal structure.

Organic letters

Org Lett. 2002 Nov 28;4(24):4189-92. doi: 10.1021/ol026816h.

[reaction: see text] A novel type of tetrathiafulvalene-cage 4 containing three monopyrrolo-tetrathiafulvalene units has been prepared employing a general and efficient synthetic approach. X-ray crystal structure analysis revealed that the cage is able to accommodate solvent molecules within a...

Statistical fluctuations of the magnetization are measured on the nanometer scale. As the experimental monitor we use the characteristic photoluminescence signal of a single electron-hole pair confined in one magnetic semiconductor quantum dot, which sensitively depends on the alignment...

PMID: 12869313
Philos Trans A Math Phys Eng Sci. 2003 Jul 15;361(1808):1363-74. doi: 10.1098/rsta.2003.1206.

Quantum information processing is performed with single trapped Ca(+) ions, stored in a linear Paul trap and laser-cooled to the ground state of their harmonic quantum motion. Composite laser-pulse sequences were used to implement SWAP gate, phase gate and...

Scalable multiparticle entanglement of trapped ions.

Nature

Häffner H, Hänsel W, Roos CF, Benhelm J, Chek-al-Kar D, Chwalla M, Körber T, Rapol UD, Riebe M, Schmidt PO, Becher C, Gühne O, Dür W, Blatt R.
PMID: 16319886
Nature. 2005 Dec 01;438(7068):643-6. doi: 10.1038/nature04279.

The generation, manipulation and fundamental understanding of entanglement lies at the very heart of quantum mechanics. Entangled particles are non-interacting but are described by a common wavefunction; consequently, individual particles are not independent of each other and their quantum...

Langmuir-Blodgett films of amphiphilic bis(tetrathiafulvalene) macrocycles with four alkyl chains.

Langmuir : the ACS journal of surfaces and colloids

Akutagawa T, Kakiuchi K, Hasegawa T, Nakamura T, Christensen CA, Becher J.
PMID: 15969416
Langmuir. 2004 May 11;20(10):4187-95. doi: 10.1021/la049950e.

Amphiphilic bis(tetrathiafulvalene) [bis(TTF)] macrocycles with four alkyl chains were fabricated as novel electrically active Langmuir-Blodgett (LB) films. Two TTF units were linked via [24]crown-8, [21]crown-7, and [18]crown-6 macrocycles, forming charge-transfer (CT) salts with 2,3,5,6-tetrafluoro-7,7,8,8-tetracyano-p-quinodimethane (F4-TCNQ) at the air-water interface...

BACKGROUND: Malaria is the leading cause of death among children less than five years of age in sub-Saharan Africa (SSA), however, precise estimates on the burden of malaria are lacking. The aim of this study was to describe temporal...
