Hoffman, Anthony J., Sridhar, Aishwarya, Braun, Phillip X., Alekseyev, Leonid, Howard, Scott S., Franz, Kale J., Cheng, Liwei, Choa, Fow-Sen, Sivco, Deborah L, Podolskiy, Viktor A., Narimanov, Evgenii E., and Gmachl, Claire

Abstract:

We report on a novel class of semiconductor metamaterials that employ a strongly anisotropic dielectric function to achieve negative refraction in the midinfrared region of the spectrum, ~8.5–13 μm. We present two types of metamaterials, layered highly doped/undoped heterostructures and quantum well superlattices that are highly anisotropic. Contrary to other...

A taxonomic study of Mononchidae (Enoplida : Nemata) inhabiting cultivated areas of Thailand

Creator:

Buangsuwon, Dara Kanhasuwon

Abstract:

Eleven species of Mononchidae Chitwood, 1937 were found among the nematodes separated from 48 soil samples in Thailand and sent to Oregon State University. Six species are newly described and illustrated including Iotonchus bangkokensis, Iotopchus ainostomos, Iotonchus chantabunensis, Iotonchus ravonqensis, fotonchus thai-Iandensis, and Miconchus triodontus. Also reported is a description...
