PMID: 24312684
Gastrointest Cancer Res. 2013 Jul;6(4):S2-9.

BACKGROUND: Pancreatic cancer is the fourth leading cause of cancer deaths in the United States. A minority of patients present with localized disease and surgical resection still offers patients the only hope for long-term survival. Locally advanced pancreatic cancer...

Using dark states for exciton storage in transition-metal dichalcogenides.

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

Tseng F, Simsek E, Gunlycke D.
PMID: 26704568
J Phys Condens Matter. 2016 Jan 27;28(3):034005. doi: 10.1088/0953-8984/28/3/034005. Epub 2015 Dec 24.

We explore the possibility of storing excitons in excitonic dark states in monolayer semiconducting transition-metal dichalcogenides. In addition to being optically inactive, these dark states require the electron and hole to be spatially separated, thus inhibiting electron/hole recombination and...

A complete high-to-low spin state transition of trivalent cobalt ion in octahedral symmetry in SrCo0.5Ru0.5O(3-δ).

Journal of the American Chemical Society

Chen JM, Chin YY, Valldor M, Hu Z, Lee JM, Haw SC, Hiraoka N, Ishii H, Pao CW, Tsuei KD, Lee JF, Lin HJ, Jang LY, Tanaka A, Chen CT, Tjeng LH.
PMID: 24410074
J Am Chem Soc. 2014 Jan 29;136(4):1514-9. doi: 10.1021/ja4114006. Epub 2014 Jan 15.

The complex metal oxide SrCo0.5Ru0.5O(3-δ) possesses a slightly distorted perovskite crystal structure. Its insulating nature infers a well-defined charge distribution, and the six-fold coordinated transition metals have the oxidation states +5 for ruthenium and +3 for cobalt as observed...

We have realized a reversible structure transformation of one-dimensional 1D K4CdCl6-type Sr3CoMO6 with the Co(2+)/M(4+) cation ordering into the two-dimensional 2D double layered Ruddlesden-Popper structure Sr3CoMO7-δ with a random distribution of Co and M (with M = Ru, Ir)...

Near-field sub-THz transmission-type image system for vessel imaging in-vivo.
