Terahertz metamaterial biosensor is a label-free affinity sensor that enhances the strength of local electromagnetic field. It extremely sensitive to changes in dielectric constant surrounding environment, thereby providing new method detecting micro or trace biological samples. In this work, highly terahertz refractive index absorber for sample proposed. The consists two concentric open metal ...

The imino-carbon double bond in the title Schiff base, C(26)H(24)N(4)O, has an E configuration. The 13-membered carbazolyl fused-ring (r.m.s. deviation = 0.056 Å) is nearly coplanar with five-membered pyrazole ring (r.m.s. deviation = 0.036 Å) [dihedral angle between the two systems = 10.4 (1)°]; the phenyl substituent is twisted by 51.1 (1)° with respect to the five-membered ring.

in this work, we investigate the transfer of some homological properties from a ring $r$ to its amalgamated duplication along some ideal $i$ of $r$ $rbowtie i$, and then generate new and original families of rings with these properties.

for a ring endomorphism $alpha$ and an $alpha$-derivation $delta$, we introduce a concept, so called skew $pi$-armendariz ring, that is a generalization of both $pi$-armendariz rings, and $(alpha,delta)$-compatible skew armendariz rings. we first observe the basic properties of skew $pi$-armendariz rings, and extend the class of skew $pi$-armendariz rings through various ring extensions. we nex...

Electric switching of reflection resonances at near-IR spectral range is experimentally demonstrated in a reflective metamaterial twisted nematic liquid crystal cell. Reflective metamaterial composed of nano-sized double-split ring resonator aperture is fabricated by a focused ion beam milling. Two-fold rotational symmetry of double-split ring resonators allows for two orthogonal polarization-d...
