Subdiffractional focusing and guiding of polaritonic rays in a natural hyperbolic material.

Nature communications

Dai S, Ma Q, Andersen T, Mcleod AS, Fei Z, Liu MK, Wagner M, Watanabe K, Taniguchi T, Thiemens M, Keilmann F, Jarillo-Herrero P, Fogler MM, Basov DN.
PMID: 25902364
Nat Commun. 2015 Apr 22;6:6963. doi: 10.1038/ncomms7963.

Uniaxial materials whose axial and tangential permittivities have opposite signs are referred to as indefinite or hyperbolic media. In such materials, light propagation is unusual leading to novel and often non-intuitive optical phenomena. Here we report infrared nano-imaging experiments...

PMID: 26467698
Org Biomol Chem. 2015 Dec 28;13(48):11645-50. doi: 10.1039/c5ob01959a. Epub 2015 Oct 15.

Annulation of 1-allyl-2-bromobenzene derivatives with internal alkynes using a hydrazone-palladium catalyst system proceeded smoothly and gave the corresponding polysubstituted naphthalene derivatives in good to high yields.

Interaction "nutrition-reproduction" in fish.

Fish physiology and biochemistry

Luquet P, Watanabe T.
PMID: 24233174
Fish Physiol Biochem. 1986 Oct;2(1):121-9. doi: 10.1007/BF02264080.

In wild fish, gonad maturation and spawning induce modifications in feeding behaviour and dynamics of body stores which are possibly responsible for metabolic disorders. Conversely, food manipulations can modify reproduction of captive female broodstock. A restricted diet during early...
